Just when the Microsoft Exchange exploit CVE-2021-26855 thought it would win the “Exploit of the year” award, it got unseated by the – still evolving – Log4J exploit just weeks before the end of the year! Had somebody asked Sysadmins in November what Log4J was then I suspect that the majority would have had no idea. It seems that the biggest challenge the Log4J exploit poses for Sysadmins is simply the fact that nobody knows all the places where Log4J is being used.

Since we’ve accumulated a lot of resources around EventSentry that are updated frequently, we’ve decided to launch a GitHub page where anyone can access and download scripts, configuration templates, screen backgrounds and our brand-new PowerShell module that is still under development.

Anybody who’s looked for answers on the Internet has likely stumbled across a “TOP X LISTS”: The “10 things famous people do every day”, “Top 10 stocks to by”, the “20 books you have to read” are just some examples of the myriad of lists that are out there offering answers. You may have even stumbled upon a few “Top 10 (or 12) Events To Monitor” articles too.

The recently discovered BlueKeep RDP vulnerability reminds us yet again (as if needed to be reminded) that monitoring RDP is not a luxury but an absolute necessity. Many organizations still expose RDP ports to the Internet, making it a prime target for attacks. But even when RDP is only available internally it can still pose a threat – especially for large networks.

Since Active Directory is the foundation of all Windows networks, monitoring Active Directory needs to be part of any comprehensive security strategy. Up to version 3.5, EventSentry utilized Windows auditing and the security event log to provide reports on: User Account Changes, Group Changes and Computer Account Changes.

EventSentry v3.5 continues to increase visibility into networks with additional vantage points, making it easier for EventSentry users to reduce their attack surface as well as discover anomalies.
