CWE Name CVEs Why this control addresses it
CWE-862Missing Authorization11,800+Mandating authorization prior to allowing remote connections addresses missing authorization for remote access.
CWE-284Improper Access Control8,100+Requiring prior authorization for each remote access type prevents improper access control over remote connections.
CWE-863Incorrect Authorization4,800+The authorization process and usage restrictions help prevent incorrect authorization for remote access types.
CWE-285Improper Authorization1,700+Explicitly mandates authorizing remote access types before permitting connections, directly mitigating improper authorization.
CWE-288Authentication Bypass Using an Alternate Path or Channel700+Authorizing remote access reduces the ability to bypass authentication via unauthorized alternate remote channels.
CWE-424Improper Protection of Alternate Path44Documenting requirements and authorizing remote access ensures proper protection of alternate paths.
CWE-420Unprotected Alternate Channel41Usage restrictions and authorization for remote access protect against unprotected alternate channels.
