Section 4 lists guidance on key exchange algorithms that SHOULD NOT and MUST NOT be enabled. You may have run a security scan or your auditor may have highlighted the following SSH vulnerabilities and you would like to address them. More often than not, this issue can occur when a server is using the default SSHD settings. The following weak key exchange algorithms are enabled : diffie-hellman-group- exchange -sha1 diffie-hellman-group1-sha1 Thanks.
