The annual Dell Technologies World conference took place in Las Vegas last week, and a few employees and managers from Sentinel were among the 14,000 attendees at the four-day event. It was one of Dell Technologies’ biggest and most action-packed conferences to date, as the company laid out their roadmap for the future that included new products/services, greater integration with VMware, and a fresh strategy for growth. While there were many important announcements made during the event, here are five that we feel are particularly noteworthy.

VMware Cloud Integrates with Dell EMC
Dell Technologies introduced a powerful new consumption-based on premise Cloud Data Center-as-a-Service that integrates multiple VMware Cloud solutions into a Dell EMC infrastructure. This includes VMware Cloud Foundation, the VMware Cloud Stack, and the hyperconverged solution VxRail. When utilized properly, it will significantly improve public cloud power and agility for organizations while making it easier to manage on premise workloads. It’s also compatible across multi-cloud environments, creating a seamless infrastructure where minor day-to-day tasks are handled by VMware and Dell EMC so IT departments can focus more on innovation and growth. The Cloud Data Center-as-a-Service is expected to be available as a subscription-based service in the second half of this year.

New, More Powerful Switches
As enterprise organizations continue to generate and consume massive amounts of data, it’s more essential than ever to have switches able to handle the traffic coming from the cloud, on premise, and endpoints. With that in mind, Dell EMC announced a new line of open networking portfolio switches called PowerSwitch. The first model set for release is the PowerSwitch S5200-ON, which is 2.5x more powerful than previous Dell EMC switches and was designed with hyperconverged infrastructure (HCI) environments in mind. Its low density connectivity helps with automation and transitional changes across all different types of deployments or upgrades.

SD-WAN Edge
Dell EMC have bundled their hardware with VMware’s SD-WAN by Velocloud to create a powerful new software-defined networking solution that’s available in one-year or multi-year subscription. SD-WAN Edge is a network optimized server designed to run virtualized network functions. The goal is to provide a more cost-effective and flexible solution to make it easier for organizations to solve their problems at the edge. SD-WAN Edge is expected to be available this July.

Unity XT
The Dell EMC storage platform Unity gets a next-generation upgrade with the Unity XT. This new version was designed with NVMe drives in mind, and is both twice as fast as the original Unity and 67 percent faster than any other storage solution currently on the market. It’s optimized for up to 5:1 data reduction and perfect for smoothly shifting data to public cloud or multi-cloud environments.

Dell EMC Cloud Storage Services
Extend your data center into the public cloud with the new Dell EMC Cloud Storage Services. This high-speed, low-latency connection uses managed services to establish a seamless combination with Dell EMC’s Unity, PowerMax, and Isilon ata center storage lines. The initial Cloud Storage offerings will include Disaster Recovery as a Service (DRaaS) as well as multi-cloud access to perform workload analytics and testing/development.

Sentinel is proud to be a Dell EMC Platinum Partner, and we’re looking forward to sharing these new solutions and innovations with you as they become available. If you would like any additional information about these Dell Technologies World 2019 announcements and how they can benefit your organization, please don’t hesitate to contact us.

As of the latest draft version of the Security Configuration Baseline document for Windows 10 and Windows Server (versions 1903), Microsoft has dropped their recommendation for a password expiration policy for both operating systems. Previously, Microsoft’s baseline recommendation for password expiration policy would force users to change their passwords every 60 days. Prior to the 60-day recommendation, Microsoft’s recommendation was a forced change every 90 days. The theory behind having users change their passwords more often, and on a regular basis was that passwords would always be “fresh” and would be harder to compromise. Additionally, compromised passwords would be usable for a shorter period of time. A moving target is much harder to hit than a fixed target, right?

To answer that question, let’s first think about the most common ways that user credentials are compromised. There are three very common attack vectors that an attacker would use to target user credentials - social attacks, technical attacks, and reconnaissance attacks.

Social Attacks

Social attacks are very common and are primarily composed of several types of phishing attacks. There are a few specific subtypes of phishing attacks, but in general the primary goal of a phishing attack is for an attacker to convince a user to hand over access credentials. A common way to achieve this is to provide the user with a fake login screen, typically on a webpage or other form, which looks authentic so that the user provides their credentials. Credentials are then captured by the attacker, and sometimes those valid credentials are passed to an authentic login mechanism so the user isn’t ever suspicious. Tools that automate this type of attack are freely available and not difficult to use. In order for social attacks to be successful, the attacker has to convince the user to perform an action which will result in compromised credentials.

Having to convince users means having to interact with them, and that opens the door for exposure to an attack attempt. If a user is wary of phishing and other social attacks, they could might alert their IT or security department. Although social attacks are still very common, most cyber criminals are looking for the path of least resistance. Technical or reconnaissance attacks tend to be a safer option.

Technical Attacks

Technical attacks rely on a hacker’s ability to compromise and exploit systems or networks in order to gain access to user credentials. These attacks do not rely on any communication with users directly, and often go undetected by IT staff. A common way of exploiting a Windows network in order to obtain user credentials is to use a tool like Responder, which exploits a flaw in the way Microsoft Link Local Multicast Name Resolution (LLMNR) works.

When a client attempts to access a trusted network resource, an LLMNR broadcast request gets sent in an attempt to locate the resource. Since the request is IP broadcast traffic, all other clients on the network segment are able to see that request. A tool like Responder will automatically respond to the client’s request and assume the role of the intended resource. Responder will respond to the request and ask for login credentials, which the client’s Windows machine is more than happy to provide. Responder captures the client’s username, NTLM/v2 password hash, domain/workgroup info, and IP address, then stops communicating with the client. After a certain period the session times out, and the client makes the request again. Responder knows that it has already captured information for that client (based on IP address), so Responder ignores subsequent requests and allows the appropriate network resource to respond. At this point the attacker can take the password hash offline to crack or use it in a pass-the-hash attack against other resources.

Reconnaissance Attacks

The third type of password attack has traditionally not been very common, but is gaining steam very quickly. Reconnaissance attacks involve collecting, indexing, and making searchable large databases of known usernames and passwords from questionable parts of the Internet (typically “deep web” and “dark web” sites). These databases contain usernames and passwords from users that have been involved in high-profile password breaches over the past several years. These password databases contain tens of billions of usernames and passwords from various system breaches ranging from the mid-2000s up to and including weeks before today’s date. Although these databases typically don’t contain password dumps from end-user systems (for example, an organization’s Active Directory database), they are still very valuable to attackers.

It’s pretty standard for users to sign up for services like Dropbox, Adobe, LinkedIn, Twitter, OneDrive, and other online services using their corporate email address as a username. It’s no secret that a very common practice among users is to reuse passwords across many sites, as doing so makes passwords easy to remember. Users also typically choose passwords that are only long enough to meet password requirements for any given system, so most passwords tend to be between 8 and 12 characters long and contain dictionary words or names. An attacker can use this information to derive a fairly powerful list of potential passwords for a corporate user based on their password history as exposed in breach databases. This list can be used against Internet-facing corporate systems in an attempt to brute-force a user’s login information, or it can be used in conjunction with a technical attack as described above to more easily crack a user’s stolen password hash.

Qualifying Microsoft’s Password Recommendation

Now that we understand the three most common vectors to obtain a user’s credentials, does Microsoft’s latest recommendation make sense?

There are several reasons why reconnaissance attacks are becoming so popular with attackers, and they’re closely tied the weaknesses we’ve all known about passwords for years. Users tend to select short, weak passwords that are easy to remember. Users tend to reuse these short, weak passwords across many sites and services. When forced to change a password at a regular interval, users tend to simply modify their existing password, typically by incrementing a number within the password or something similar. If systems prevent users from using dictionary words in their passwords, users tend to replace letters of a dictionary word with numbers or special characters that look like those letters (4 for A, ! for i, 0 for O, etc.) Modern password cracking tools have automated rules that exploit all of these weaknesses via automated guessing to the tune of literally billions of guesses per second using a modern GPU.

Knowing user habits in regard to the creation of weak passwords, and knowing how users typically only increment passwords when forced to change them on a regular basis, Microsoft understands that forcing a user to change a weak password every 3 months isn’t nearly as important as forcing the user to create a “long and strong” password once and allow them to use it for a much longer period of time. If a user increments a number at the end of weak, 8 character password, the password is still weak and can still be cracked in a matter of hours or days. If an attacker knows this password and the user changes it, the attacker can simply make logical guesses to figure out the “new” variant with ease. If a user isn’t forced to change a strong 24-character password for a year or two that’s fine, because the length of that password alone would take 20+ years to crack with modern technology.

So to answer the original question, yes, Microsoft’s recommendation of eliminating password expiration policies does make sense, however, the shortcomings of the initial password requirements should also be remedied. Microsoft acknowledges that password expiration policies don’t make systems any more secure. From the latest Microsoft Security Baseline document:

“Periodic password expiration is a defense only against the probability that a password (or hash) will be stolen during its validity interval and will be used by an unauthorized entity. If a password is never stolen, there’s no need to expire it. And if you have evidence that a password has been stolen, you would presumably act immediately rather than wait for expiration to fix the problem. … And if it’s not a given that passwords will be stolen, you acquire those problems for no benefit. Further, if your users are the kind who are willing to answer surveys in the parking lot that exchange a candy bar for their passwords, no password expiration policy will help you.”

Microsoft goes on to explain that they are not proposing that organizations weaken requirements for minimum password length, history, or complexity, as all of those factors combined are much more important than forced password expiration.

Ways to Improve Your Password Security

Ideally, we would do away with passwords altogether and use a better form of authentication. This is the dream, but the reality today is that many systems will still only allow authentication via passwords. Since our reality includes a system whereby users are expected to create and manage secure passwords themselves, the following steps should be taken to make the most of a less than optimal situation.

     +Use multi-factor authentication (MFA) wherever possible. This is especially important on Internet-facing services like VPN and Outlook Web Access / Office 365. Often, organizations neglect the importance of securing email with MFA. If an attacker can access a user’s inbox via Outlook Web Access, s/he can dump the Global Address Book and easily harvest usernames for everyone inside the organization. If that email account can be used as a second factor avenue for something like a VPN login, the VPN would then be compromised as well.

     +Enforce banned password lists in Active Directory. Microsoft provides a service through Azure AD that can be implemented with on premise Active Directory. This service automatically checks user passwords against a large database of known weak and compromised passwords, and if whatever password the user attempts to use matches a password in that database, the system will not allow the password to be used.

     +Perform regular password audits against the Active Directory SAM database. As an administrator, it’s rather trivial to export a dump of the password hashes within the Active Directory database. This dump can then be provided to a trusted partner such as Sentinel, where a skilled penetration tester can use common password databases, breach password databases, and heuristic brute force attacks against hashes within the database to expose weak passwords. This will measure the effectiveness of an organization’s password policy, as well as the effectiveness of its users to choose secure passwords.

     +Ensure that all Microsoft best practices are followed in regard to how passwords are handled from a technical perspective. Disable the use of LLMNR on the network via Group Policy. Require Server Message Block (SMB) signing to mitigate against SMB man-in-the-middle attacks, which can be used to expose password hashes. Add a DNS entry in Active Directory to mitigate the ability for attackers to exploit Web Proxy Auto-Discovery Protocol (WPAD) to obtain cleartext credentials from users.

     +Educate users on the dangers of social engineering attacks. Sentinel’s Advisory Services team offers training to teach users how to identify many types of attacks, including obfuscated links in email, dangerous attachment types, forged emails that appear to come from a trusted source, and many others. Education like this helps users stay safe at work as well as at home.

     +Encourage users to create passwords that are “long and strong.” A long and strong password should contain more than just lowercase letters, but doesn’t have to look like alphabet soup to be effective. A password like “S&&4$2j0*jf!!3Nmf)3=@+2&5” might take a long time to crack, but it’s impossible to remember, frustrating to type, and will get written down. Something like “&WeWentToTheZooLastWeek&” is easy to remember, is 24 characters long, contains characters from 3 attack sets (upper, lower, special) and should take a prohibitively long time to crack. Using “pass phrases” like this instead of “passwords” is quickly becoming popular to create long and strong passwords. To encourage the use of pass phrases, high minimum password length policies can be implemented, but only after users are educated on how to create easy to remember long and strong passwords.

Personally, I think Microsoft’s recommendation is a sound one, as long as the above information is followed. It serves to start a conversation about how we think of and formulate passwords today, and helps us to understand that they are typically the weakest link to an organization’s security. Taking steps to mitigate weak password creation and use, discouraging password reuse, and implementing multi-factor authentication wherever possible are solid steps in enhancing the security stigma that surrounds passwords.

Cisco Digital Network Architecture (DNA) has exploded in popularity recently as an advanced software-defined networking platform that contains a number of different features and innovations designed to enhance business growth, agility, and security. There are a multitude of benefits worth exploring if your organization is interested in building or enhancing a software-defined network, and Sentinel is proud to offer DNA in a variety of formats and bundles to help our customers find the right solution for their specific environment. To help give you a better idea of what Cisco DNA is all about, Sentinel CTO Robert Keblusek provided answers to a few commonly asked questions:

What is Cisco DNA?

Cisco DNA is software-defined networking designed to support digitization efforts. This includes mobility, cloud, and Storage as a Service (SaaS) consumption, along with Internet of Things (IoT) services. 

Software-defined networking eliminates the need to update firmware, software, and configurations on tens or hundreds of devices over many months. Studies show that 43% of network administrators’ time is spent troubleshooting, while 95% of overall IT tasks are done manually. Updating networks with security patches alone is a daunting task for most organizations, and can even require a team effort that includes CCIEs or a managed service provider. DNA makes these updates simple and fast through automation. Organizations then benefit from a more secure network with strong policy and governance while shifting their most skilled IT resources to focus on more impactful business needs. 

How does DNA help with cloud and SaaS consumption?

DNA extends into the wide area network where SD-WAN services allow for a smart edge. This edge has security natively embedded and has the ability to think and route packets appropriately. Gartner estimates over 20% of Office 365 deployments struggle due to networking issues or latency. Software-defined networking such as DNA can be a solution to these issues. With Office 365 and content collaboration at the center of digitization efforts for many organizations, this is a big deal. 

In the past, maybe 80% of your traffic went from the end user to your data centers. With cloud and SaaS, that traffic now goes to the cloud. This changes things and you need an agile, software-driven network to continually adapt to these needs. 

How does DNA help with security?

DNA was also designed with security embedded instead of it being an afterthought. Security features such as deep inspection of encrypted traffic, rapid threat containment, profiling, posturing, and identity access settings are all easily deployed and maintained across your entire network. 

What is a good way to get started?

DNA Assurance provides in-depth visibility to the transactions on the network and can minimize troubleshooting.  In addition, users can resolve issues faster because Assurance empowers the help desk. Highly skilled staff no longer need to speculate on what might have occurred because they have real analytics showing detailed information. Assurance works with most existing Cisco networks and is a great start for organizations to build toward the full DNA software-defined experience.  

Sentinel has some great FastPath bundles for DNA Assurance to help your organization see the value very quickly and economically. Please contact us for further details or if you have any additional questions about Cisco DNA.

At Sentinel, we love movies. We’ve even been known to host a movie premiere or two for our customers. While superhero films and other blockbusters understandably attract a lot of attention, we also get excited about smaller movies, especially when the plots focus on technology and innovation. It can be a real kick to see a fictionalized version of an IT department or hackers launch a “cyber attack,” even if it bears little resemblance to actual reality.

One of the more recently released technology-focused films is the financial drama/thriller The Hummingbird Project. It received a limited U.S. theatrical release in mid-March and can still be seen in certain markets depending on where you live. The plot centers on Vincent and Anton (Jesse Eisenberg and Alexander Skarsgard), who are cousins and work together at a high-frequency trading brokerage firm in New York. Vincent is the hustler and big idea man, while Anton is the brains focused on developing new ways to help the firm gain a little extra edge over the competition.

Both Vincent and Anton are frustrated with their jobs and feel under-appreciated, so they hatch a plan to forge their own path in the world of high-frequency trading: Create a 4-inch wide, 1,000-mile long fiber optic cable that will go in a straight line from a stock exchange in Kansas City to a data center in New Jersey. Any Wall Street brokerage firm with access to that cable would receive a one millisecond (or one flap of a hummingbird’s wing) advantage on all trades, and in turn net hundreds of millions of dollars in profits.

The primary challenges they face are twofold: First, they need to find a way to forge a completely straight fiber optic cable path between their destinations that includes securing permissions and digging through privately-owned land, government-owned land, and the Appalachian Mountains. Second, the quality of the cable and straightness of the path don’t automatically provide that single millisecond boost in speed, so they need to develop a new mathematical algorithm to help them reach that point. Thankfully they have a multi-billionaire backing their project, so funding to pay landowners and drill teams and for specialty equipment is one of the least of their worries.

That’s the basic setup of The Hummingbird Project, but as the film moves forward things become increasingly complicated as Vincent and Anton face off against their ruthless former boss (Salma Hayek), stubborn landowners and environmental concerns, plus moments that threaten their physical and mental health. Of course if it were easy, that would make for a pretty boring and uneventful movie. As it stands, there’s a whole lot of plot to take in over the film’s two-hour runtime, and the shift away from the actual cable pipeline project to dive deeper into the personal lives and sentimental reflections of the two main characters feels just a bit cliché and a minor misstep from writer-director Kim Nguyen.

From a technology standpoint, The Hummingbird Project fares better than most when it comes to providing a realistic portrayal of working with fiber optic cables and data centers. Fiber splicing, cable installation, and data centers are all displayed with relative accuracy, and the filmmakers brought in IT industry experts as consultants to ensure the actors and production team understood the concepts and equipment being used. It’s also worth noting that the film is set in 2012, and the technology used to power high-frequency trading has already evolved well beyond the use of fiber optic cables (the characters smartly note the cable they’re installing will be obsolete within a few years). Still, there are plenty of interesting and innovative uses for fiber and other high-speed technology solutions today that go well beyond the financial markets. 

If you’re interested in learning more about cabling or other data center solutions and services to help your business, please contact Sentinel for more information. We also work closely with plenty of finance customers, and would be happy to discuss the latest IT innovations that are powering the financial industry.

The Hummingbird Project is currently in limited theatrical release. Check to see if it’s still screening in your area by going here.

This morning, Sentinel held a safer schools seminar at our Downers Grove headquarters for some of our education customers. Our experts highlighted the latest security systems and notification technologies intended to quickly alert teachers, students, staff, executives, and local authorities about dangerous or emergency situations so they can respond according to previously established safety guidelines. The educators in attendance also participated in a roundtable discussion focused on response solutions and strategies, asking plenty of questions and sharing plenty of ideas. Here are some insights into Sentinel’s comprehensive and innovative approach when working with schools to improve their safety.

Sentinel begins every new school safety engagement by reviewing your current mass notification solution and determining how it aligns with your current goals and requirements. Our team then builds a new or advanced solution around those requirements, including the design and review of triggers and notification devices. Once approved, we will deploy the solution, train designated people so they know how to use it, and engage with your executives so they understand what’s in place.

Sentinel’s Advisory Services can also come in and help your school, university, or educational institution build stronger security plans based around the National Incident Management System (NIMS) approach. It is what all first responders use to manage every type of emergency situation. It’s important that executives and other staff within your school district are educated on NIMS, particularly if they are responsible for managing an incident, because it allows you to build a plan and know what the first responders are going to ask when there’s an incident.

You want to be prepared to handle anything. If something happens and you need to evacuate the school, what’s the plan for that? What happens if students are at a museum on a field trip and something happens there? Would the instructors know what to do with the kids at that point, and how to communicate with them and those back at the school? The Sentinel Advisory team works with you to help build a plan and prepare for almost any type of scenario. We encourage people outside of the IT staff, such as executives and school board members, to participate in this process and make sure these plans are comprehensive and meet your needs. We’ll also coordinate with any local police department and public safety groups to integrate them into your security systems and processes, because they have their own ways of doing things. The ultimate goal is to build a response plan that satisfies everyone.

Involvement has to be across the board. It can’t just be the IT guys going out just saying, “You need a speaker here, a panic button there, just add a strobe light in this hallway, and that’s it.” You need everybody involved so they all understand what you’re doing and what you’re providing. A lot of companies are selling school safety solutions, and you could buy them almost anywhere, but Sentinel goes in and works with the whole staff as we’re bringing in all the different components while also understanding what you already have in place today. Very few businesses are willing to do that. We don’t want to just sell you a box. We want to give you a complete solution and strategy that’s going to protect yourself, the staff, and all of the students eager to learn.

If you would like to find out more about the solutions and services Sentinel offers to help keep your school safe in the event of an emergency, please contact us.

At Sentinel, we’re all about providing our customers with innovative and industry-best technology solutions designed to enhance the way business is conducted and promote growth. Our “Always Leading” approach also means that we keep a close eye on trends and new developments throughout the IT industry and pass that knowledge along to our customers so they can make the most informed decisions when it comes to their technology investments.

One of the ways we like to keep our customers educated is by hosting events. Not only do events provide an opportunity to learn more about a specific topic or solution with some of our experts, but they also allow us to get to know our customers and their needs better while building a stronger relationship. No matter if you’re a long-time Sentinel customer or are brand new to us and have never attended a Sentinel event before, we’d love to see you! Here are some fun and interesting events we have coming up over the next month. Please visit the Events page on our website or click the individual event links below if you would like to learn more and RSVP!

Organizations interested in getting a different management and visibility perspective of their technology consumption should consider adopting Cisco Meraki. It combines wireless (MR), cameras (MV), voice and switching (MS), plus security (MX) technologies into a single, cloud-based platform that’s easy to use and manage. You don’t need to deploy it for every piece of your environment, but it does offer significant advantages for those working with multiple or complex IT environments such as public school systems, government agencies, and multinational corporations.

The primary benefits of Meraki are ease of management, ease of deployment, and simple visibility. Three years ago, I was working with a customer that had separate systems for each piece of their environment. They had their switching infrastructure on one system, their firewalls on another system, their access points on a third system, and a small closet with monitors for their security camera system. The IT director wanted a solution that enabled him to manage as much of the environment as possible from the least number of systems possible so he and his team could respond to issues quickly. He immediately saw the value of having a standardized platform like Meraki with the ability troubleshoot, manage, patch, and deploy different technologies through one system.

As another example, a long time Sentinel customer was preparing to open up a new remote office location. We had already deployed non-Meraki wireless technology for this organization over the last couple of years, but they wanted to give Meraki a try this time because of the camera system and the ability to manage everything from a single pane of glass. They also needed the solution to be deployed in under 90 days, which meant we had to move quickly and order the equipment, configure it, install it, and then train their IT staff on how to use it.

That type of conversation seems to happen more and more these days. Organizations are looking to shorten the time it takes to deploy a normal, complex, and expensive solution while also making it manageable for end users who are working at a remote location without any on premise IT personnel to troubleshoot any issues. They need the ability to connect and integrate with the system from a branch location on the other side of the country to make adjustments as needed and quickly respond to end users.

Sentinel is responsible for properly qualifying our customers to make sure the technology they want actually aligns with and can fulfill their needs. An ideal candidate for Meraki should be looking to consume more than one piece of the proverbial pie. If you only want to look at switching, there are certainly benefits to be found in Meraki’s cloud management tools, deployment and update capabilities, along with its troubleshooting features. But there are other cloud platforms on the market that are fully devoted to the switching side of things and might be a better fit for your organization. If you’re looking to combine and integrate two or more systems and appliances however, like switching and wireless or switching and security, then Meraki is second-to-none in the industry just because of what you can see and what you can touch.

If you are interested in learning more about Cisco Meraki and how it can benefit your organization, please contact Sentinel for more information.

At Sentinel’s Tech Summit earlier this year we discussed a variety of topics, but a common theme among them was the proliferation of cloud services. My presentation focused on the benefits to operational maturity that can be achieved through the strategic adoption of already established cloud services rather than building your own. Implementing a best practice alignment framework can not only improve your cloud operations, but has a wide-range of advantages for your workloads and infrastructure elements no matter where they are running.

There are plenty of great best practice alignment frameworks available today to help you get the most out of your cloud and premise infrastructure investments, including the AWS Well-Architected Framework, the Microsoft Operations Framework, the Information Technology Infrastructure Library (ITIL), and by association, the Capability Maturity Model Integration (CMMI). Do some research and choose one that’s best suited to your particular organization and environment. If you are interested in learning more about methods and strategies to measure your cloud operational maturity, I’d recommend checking out books like Eli Goldratt’s The Goal, The Phoenix Project, or even Simon Wardley’s Maps.

The cloud provides an opportunity for organizations to consider change and reevaluate the status quo. More often than not, the discussion will be more complex than simply moving some virtual machines to the cloud. It enables cloud service providers and standards agencies like the National Institute for Standards and Technologies (NIST) to develop frameworks and offer guidance on how to properly measure and improve your IT posture. The AWS Well-Architected Framework is a great example of this, as it features specific questions that encourage you to consider innovative ideas and approaches you might not have come up with on your own. These frameworks also incorporate on premise infrastructure elements so you’re not just focusing on the cloud.

One example I used during my presentation is a question from the Reliability Pillar of the AWS Well-Architected Framework: “How do you monitor your resources?” This single question can lead to multiple in-depth technical discussions about what is most valuable, from a stack of switches to your organization's enterprise resource planning (ERP) system. Every piece plays an important role in your IT operations, whether you own the facility it resides in or not.

This is just a small portion of what was covered at the Tech Summit. There were many other important topics worth exploring in greater detail, including new identity management tools that incorporate certificate-based authentication or single sign-on technologies, as well as modern systems management that use Infrastructure as Code (IAC) or Functions as a Service (FaaS). Sentinel offers Jumpstart packages designed to help your organization make real progress on its cloud journey. They focus on establishing public cloud landing zones to create a standardized configuration baseline, along with shifting your backup and disaster recovery solutions to the cloud as a way of modernizing your existing processes. If you are interested in learning more about these packages or any of our other CloudSelect offerings, please contact us.

Healthcare professionals from around the world gathered in Orlando last week for the annual HIMSS (Healthcare Information and Management Systems Society) Conference & Exhibition. The five day event focuses on healthcare education, innovation, and collaboration through the convergence of information and technology, so providers can deliver top quality, transformational patient care. There are plenty of classes and seminars to choose from, as well as special programs and networking opportunities. It’s nearly impossible to detail all of the fresh ideas, products, and trends that were highlighted over the course of the week, but here are some of this year’s notable highlights.

The use of artificial intelligence (AI) and machine learning in hospitals and medical centers has shown slow but steady growth over the last few years. There are many ways to deploy this type of technology in a clinical setting, but most of the primary benefits thus far have come in the area of research, as analysis of patient data allows for better and more predictive diagnoses. Adoption has remained slow overall for a number of reasons, but mainly because most healthcare organizations aren’t yet sure how to properly incorporate AI into their day-to-day operations in order to maximize its effectiveness. Continued concern over patient safety and the ethical impacts of how patient data might be used have also held back its expansion. Recent use case studies at the university level have generated very promising results so far, which suggests a brighter future ahead.

One path to advanced technology implementation by healthcare organizations involves deploying an adoption model developed by HIMSS. There were a few new ones announced at this year’s conference, but the most interesting among them is INFRAM (Infrastructure Adoption Model). It is designed to help healthcare organizations assess and map the technology infrastructure capabilities required to achieve their business goals, benchmarks, and standards. Your facility’s IT adoption and maturity levels are ranked according to an international eight stage model, so you can better understand how to proceed in a way that improves care delivery, reduces cyber risk, and establishes a clear path toward future development.

HIMSS also announced the results of their 2019 Cybersecurity Survey, which pooled data from 166 different healthcare security professionals to provide insight into what steps organizations are taking to protect their information and assets.

     +As the number of security incidents continues to rise, virtually every U.S. healthcare organization experienced a significant breach in 2018. Most were the result of attackers using email with malicious links to gain access to networks and credentials.

     +Healthcare organizations are starting to place a greater emphasis on cybersecurity, allotting more money to spend on protection technologies.

     +Complacency when it comes to cybersecurity creates a significantly higher risk for healthcare organizations. It’s essential to consistently evolve your security solutions and strategies, because hackers are always changing their approach and developing new tools in an attempt to breach your environment.

     +There are notable cybersecurity gaps in many healthcare organizations, particularly those conducting day-to-day operations with legacy systems. Gap and penetration tests should be a regular occurrence in healthcare IT departments to ensure sensitive and private data remains safe in the event of an attack.
