LONDON, Feb. 11, 2021 /PRNewswire/ Redscan, the Managed Detection and Response and Penetration Testing specialist, today released its new report NIST security vulnerability trends in 2020: an analysis .
NIST logged more than 18,000 vulnerabilities in 2020, over 10,000 of which were critical or high severity – an all-time high. Redscan s analysis also looks beyond severity scores, detailing the rise of low complexity vulnerabilities as well as those which require no user interaction to exploit. These trends may be of concern to security teams, highlighting the need for organisations to focus patch management efforts and adopt a multi-layered approach to vulnerability management. However, there are also positive trends, such as a decrease in C
