Network Security Trends: August-October 2021
Summary: Unit 42's August-October 2021 analysis registered 7,064 new CVEs, of which 5,101 scored medium severity or higher, and found that 74.4% were remote vulnerabilities exploitable over a network while only 25.6% were local. From more than 10 million sessions observed on Palo Alto Networks Next-Generation Firewalls, researchers filtered to 3.79 million valid malicious sessions and reported that high-severity attacks exceeded half of observed attacks for the first time, with information disclosure ranking first by category and code execution second.
What you should know: Nearly three-quarters of the quarter's new vulnerabilities could be attacked over the network, and attackers concentrated on high-severity flaws from 2020-21 - which means a late or improper patch is the exposure, not an exotic exploit.
