- 2,500 belongings amongst these surveyed have been nonetheless utilizing TLS 1.0, which Tenable mentioned is “a 25-year-old safety protocol launched in 1999 and disabled by Microsoft in September 2022.”
“This highlights the numerous problem organisations with in depth web footprints face in figuring out and updating outdated applied sciences,” Tenable mentioned in a press launch.
Misconfiguration of inner belongings
Numerous belongings initially supposed for inner use have been inadvertently uncovered. Tenable discovered 4,000 that had been misconfigured in ways in which made them accessible by exterior actors.
“Failing to safe these inner belongings poses a big threat to organisations, because it creates a chance for malicious actors to focus on delicate data and demanding techniques,” the agency mentioned.
