Rapid7’s research found that the security of the internet overall is improving. The number of insecure services such as SMB, Telnet, rsync, and the core email protocols, decreased from the levels seen in 2019.
Vulnerabilities and exposures still plague the modern internet even with the increasing adoption of more secure alternatives to insecure protocols, like Secure Shell (SSH) and DNS-over-TLS (DoT).
