If my security agents were not working correctly, then I would get an alert. Since no one said there is a problem with my security agents, then everything must be ok with them. These are just a couple of the assumptions that we make as cybersecurity practitioners each day about the security agents that serve to protect our respective organizations. While it is preferable to think that everything is ok, it is much better to validate that assumption regularly. 

I have been fortunate to work in cybersecurity for many years and at several diverse types of organizations. During that time, I always found it helpful to check on the status of the security agents periodically. I have found that by scheduling regular and recurring calendar reminders, I can better validate the assumption that the security agents are working as intended. Specific areas of focus include both confirming the security agent is installed correctly and that it is performing the actions specified in the policy. 

Central monitoring consoles are a great place to start for security agents that have not communicated back to the console within an acceptable time. The output from the console can be compared to the Inventory and Control of Hardware Assets to ensure that every system has a security agent installed. Whether an automated or manual task, this practical step can help to validate that assumption. 

What assumptions can you validate today? Think about that over the weekend and determine to take action on Monday morning! By being intentional to validate the health of your security agents, you can do a great deal to validate the assumptions you are making.

How to a how long can you stand not to know when your security agents are not working as expected? Let us know of your successes in the comments section below!

Enter comment here... a fake TeamViewer page, and that page led to a different type of malware. This week's infection involved a downloaded JavaScript (.js) file that led to Microsoft Installer packages (.msi files) containing other script that used free or open source programs.
distribute malware. Even if the URL listed on the ad shows a legitimate website, subsequent ad traffic can easily lead to a fake page. Different types of malware are distributed in this manner. I've seen IcedID (Bokbot), Gozi/ISFB, and various information stealers distributed through fake software websites that were provided through Google ad traffic. I submitted malicious files from this example to VirusTotal and found a low rate of detection, with some files not showing as malware at all. Additionally, domains associated with this infection frequently change. That might make it hard to detect.
