Reflections of a Sentinel Intern
by Quade Kayle, Software Development Intern
Greetings reader, my name is Quade and I am an incoming senior at Carthage College. I hail from the lovely suburban town of Libertyville, Illinois, just about an hour outside of Chicago. I have been studying Computer Science at Carthage for three years now, and I am very excited to be finishing my last year with such a rigorous and well-developed program. This summer, I am employed as a software development intern at Sentinel Technologies.
It was a mid-afternoon in March when I received a call from Sentinel with an offer to spend my summer with them as an intern on their software development team. I jumped around my dorm room trying to contain my excitement. After I accepted, I let it set in that I would be spending a summer in Downers Grove doing what I love: development.
Development, however, involved more than just my fingers hitting the keyboard in repeated patterns to produce a desired result. To me, this summer was about development in a variety of ways: as an application developer, a young professional, a runner, and a human being. With support from my professors and mentors, I soon learned the ins and outs of the development process. Beyond that, I also picked up valuable life skills such as how to best manage my time, how to properly conduct myself in a business environment, and how to minimize my stress levels.
When I started at Sentinel we had orientation,
where the first lesson was to be ready to learn every day. I hit the ground
running by studying the many different applications and frameworks the company
and a plethora of related tools. My intent was to start making an impact right
away, but just like development, it was going to be a process. You need to know
how to walk before you can run.
Once I was assigned my first project, things began to move very quickly. I was eager to see my project start from nothing and blossom into something truly great. One of my goals was to be proud of my work, and that was putting it mildly. I added in features and tried new and interesting solutions to problems that otherwise seemed impossible. My supervisors began laying out new prompts and additions to my projects, but as the list grew, so did my anxiety. I worried about how I was going to make it all work. But just as quickly as those thoughts came, they disappeared as I told my supervisors I’d get it done.
I am very fortunate to be blessed with supervisors that are eager to teach me as well. What I value the most from my relationship with them is they don’t feel the need to hold my hand and guide me through every little thing. Instead, they point me in the direction I need to head and then let me discover the path to get there. Their methods are incredible and I feel lucky to work with such strong leaders. The lesson I learned is a universal one: do not expect to be coddled. Situations just like this one are helpful for the development of my character. It's a very important lesson I will take with me forever.
Unfortunately, not all my days were personal
journeys with valuable lessons to learn. Some days were the typical 8:30 to
5:00 day where I accomplished very little and felt very discouraged. I am driven
by success, and on the days where I failed to achieve what I needed to, I would
drive home quietly contemplating how I could have done better. The first couple
of times this happened, I wasn’t sure how to react. I soon learned that this
valuable time can be used for self-reflection and growth. Instead of neglecting
my feelings, I wrote them down, went for a run, and thought hard about what
made the day unsuccessful in my opinion. The day didn’t have to end at 5:00; I
could always come up with an idea or activity to shift things in a positive
While the bad days came, the amount of good days outnumbered them. I have been working on four different projects this summer, three of them being considered complete. A couple have been with another intern on my team named Ryan. My supervisor has to inspect them and prepare them for production before they can be used, but fortunately enough, I have already had one of my projects pushed to production! It is a wallboard that is displayed in different areas around Sentinel, and the day that it was pushed to production I got to see a real project I developed being put to practical use. It was a great feeling, and I am very excited for when my other completed projects get moved to production and are used by the staff at Sentinel. As an intern, it is rewarding know I am responsible for products that are being utilized.
My continuing summer project has been very rigorous, and as the summer goes on, my supervisors have asked me to add more and more difficult features. These have been great learning experiences, and each time I complete a feature, I am eager to complete another one. I refuse to stop until a feature is done. It’s almost as if you can accomplish anything if you are willing to work hard enough.
Each day there is a takeaway, whether it be learning
how to drive in rush hour traffic or understanding how to conduct myself on a
bad day. While my growth as an adult started when I stepped foot onto the
Carthage campus, my internship at Sentinel is responsible for an incredible
amount of exposure and discovery, not only professionally as a developer but as
a young adult figuring out the world. I have a couple weeks left at Sentinel
before my time is done here, but remain excited for the new lessons I will continue
A Recap of Sentinel's 2018 Security Summit
Last Thursday, Sentinel held our annual Security Summit at Arlington International Racecourse in Arlington Heights, IL. We were joined by more than 100 of our customers, who came to learn more about the many different types of security solutions available to help protect their organizations, as well as get their most pressing security questions answered by our panel of industry experts. It was a great day, and we hope everyone that attended came away with a better understanding of the current security landscape and steps they can take to improve their own security posture.
In case you missed it or were unable to attend, we wanted to share a brief summary of some of the topics that were discussed and questions that were asked during the event. If you are interested in learning more about any of these things, please don’t hesitate to contact us. A special thank you to our partners at Cisco, Attivo, AlienVault, and Duo for their hard work and expertise that helped make this day a success!
-The top two attack vectors today are email and malicious websites. Hackers will send a targeted phishing email that looks like it was sent by a friend, family member, co-worker, or boss, which contains harmful content or links designed to infect your system or obtain key personal information.
-Regular assessments, at least one or two every year, are essential to make sure your security is doing its job. Penetration tests are strongly recommended as well.
-Sentinel strongly recommends organizations have at least two endpoint security solutions installed in their environment, such as Cisco AMP with Umbrella. Multiple endpoint security solutions create layers of protection, as each one looks at different aspects of the environment.
-Segmentation in your environment is of paramount importance. If you have a server farm, for example, segment it. Segment as many things as you can, because it makes it much more difficult for attackers to move around and gain access to sensitive data.
-You not only need security to identify and help stop threats, but also to remediate and patch after an attack. If you don’t currently have a patching cycle already in place, you are already in danger. There are new vulnerabilities emerging every day/week, and regularly patching keeps your protection solutions up to date.
-A public cloud uses the resources of outside organizations (such as Azure and AWS) to store and operate portions of your environment. Your business won’t be able to manage and adjust every aspect of the public cloud, but above all else you need to maintain control over who has access to private and sensitive data. Private cloud is fully controlled by your organization, meaning all responsibilities are yours, including security and access to data.
-A strong cloud security posture should emphasize visibility so you who has access to what. For example, if an employee downloads a tool or app, they might agree to terms of service that includes access to their private accounts or email and not realize it. Proper cloud security is designed to spot these vulnerabilities and make sure nobody is granting permissions that can open your organization up to danger.
-Cisco Umbrella offers cloud security to help identify what other security products are missing. It is a great add-on for all types of environments, including Microsoft Office 365.
-Cisco Stealthwatch Cloud will monitor your cloud environment using behavioral analytics and keep an eye on any strange activity that deviates from standard operations.
-Cisco Identity Services Engine (ISE) controls endpoint access to the corporate environment. If a user tries to log in to your network using an unapproved, non-corporate device, they may be denied access out of concern that device may not be secure.
Security Assessments and Security Advisory
-Your organization needs a security strategy and roadmap. Assessments, gap analysis, and penetration tests are so important. Vulnerability scans help identify dangers in your environment.
-If your organization is PCI compliant, quarterly vulnerability scans are required, though Sentinel recommends monthly vulnerability scans. If you’re non-PCI compliant, your organization should get security and risk assessments at least once or twice a year.
-If an attacker obtains your system administrator’s username and password, your whole network is likely going down, because they can exploit that to gain access anywhere and cause catastrophic damage across servers and systems.
-Having a two-factor authentication system in place is very important to protecting access and preventing attacks from spreading. A platform like Duo verifies the identities of users and the security health of their devices before they are allowed to log in to your environment.
Security Incident Event Management (SIEM) and Security Operations Center (SOC)
-High costs and a lack of manpower are the two primary reasons why many organizations haven’t yet adopted a SIEM. Those that do are often overwhelmed with SIEM products, which have all kinds of alerts and false positives that take too much time and energy to go through. Sentinel offers a managed SIEM option that is inexpensive and only sends important alerts and updates to your IT team to help improve the focus on the security of your environment.
-Sentinel’s SOC monitors your environment 24x7x365 to ensure your critical data remains secure. Once an alarm is triggered, our SOC works closely with your organization to help shut down the attack.
-Quarterly quality assurance meetings for our SIEM and SOC offerings enable the Sentinel team to talk with you about security incidents and make recommendations on next steps and ways to improve your security posture. Sentinel wants to help you achieve your security goals, even if it takes years to build, piece by piece.
-In the event your environment is compromised,
Attivo offers deception technology that creates decoys and other lures for
attackers to follow, pulling them away from your critical data and systems so
you can minimize their access and any potential damage.
