Tenable Research Publishes 2021 Threat Landscape Retrospective

On January 19, Tenable Research published its second-annual Threat Landscape Retrospective (TLR). This report provides a review of the year in vulnerabilities and breaches, with insights to help guide cybersecurity strategy in 2022 and beyond.

The report is divided into three sections:

• Section one of the report analyzes the year’s top vulnerabilities and zero-days, including exploring their origin and impact. For example, flaws in Microsoft Exchange and Windows Print Spooler dominated focus.
• Section two is about threat actor activity in 2021. We review the outcome of their efforts, including data breaches, ransomware and attacks against the supply chain. 
• Section three is a digest of every major vulnerability from the year, covering over 300 vulnerabilities.

In the already busy day security personnel, the TLR helps make sense of a cacophony of vulnerabilities from a year that was unlike any other.
