Security Information and Event Management (SIEM) is the combination of Security Information Management (SIM) and Security Event Management (SEM) systems. SEM systems store and interpret logs for real-time security event analysis which enables quick defensive action. SIM systems collect data for trend analysis and provide automated reporting. By combining these two technologies together, a SIEM provides rapid identification, analysis, and recovery from security events.

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.

Our log management solution, EventLog Analyzer, has had yet another busy year. Being named in the 2021 Gartner Magic Quadrant for SIEM for the fifth time was one of the high points. We also had the satisfaction of helping many organizations ensure their overall cybersecurity health with new features to meet evolving demands. Our journey in 2021 With many organizations adopting hybrid work models over the last year, there was a steady increase in the volume and severity of cyberattacks.

There’s only one thing that’s certain in cybersecurity: The cyberthreat landscape is constantly changing, and the tools and solutions we have at our disposal to combat cybercrime must continue evolving if we are to stay ahead of — or at least keep up with — them. As 2021 winds down, the Devo security team is already looking ahead to the most pressing cybersecurity trends likely to appear in 2022. Here are my top three predictions for the new year.

A critical vulnerability in the popular log4j library is currently being actively targeted on a broad global scale and possibly exploited based on advisories from multiple CERTs and vendors: CISA, Apache, etc. This Java library is integrated into many IT and DevOps tooling and workflows. On Dec 10, 2021, Apache released version 2.15.0, fixing CVE-2021-44228 (dubbed Log4Shell) an RCE with a maximum CVSSv3 score of 10.

While we are a long way from implementing Skynet, using machine learning combined with automation to make real-time decisions is here. In a recent talk at Sumo Logic Illuminate, Dave Frampton, General Manager of Cloud SIEM and Security Analytics, discusses the future of security with Vijaya Kaza, Head of Engineering and Data Science for Trust & Safety and Chief Security Officer at Airbnb. Kaza describes how automation, machine learning and AI can strengthen a company's overall security posture.
