Industry-First Research From Tenable Calculates External Attack Surface of U.K.s Largest Organisations
Summary
An inventory of the external attack surface of 22 of the U.K.’s largest organisations1 [as listed by the FTSE top 50] were examined on Friday, October 29, 2022. The results show how complex, geographically dispersed, and hybrid these environments have become, and illustrate the sheer scale of the cybersecurity architecture that needs to be secured. One striking observation is that 100% of organisations had web-based assets that still support TLS 1.0 [a security protocol first defined in 1999 for establishing encrypted channels over computer networks] that was disabled by Microsoft in September [2022]. Internet-facing assets are not just commonplace, but essential for organisations in the modern business world,” said Jeremiah Grossman, Security Strategist, Tenable. • Tenable examined 22 companies, chosen at random from the FTSE Top 50* • In the context of this alert: • An asset is a domain name, subdomain, or IP addresses and/or combination thereof of a device connected to the Internet or internal network.
