ESXI-65-000016 – The ESXi host SSH daemon must not permit user environment settings. Details SSH environment options potentially allow users to bypass access restriction in some configurations. Users must not be able to...
ESXI-65-000017 – The ESXi host SSH daemon must be configured to only use Message Authentication Codes (MACs) employing FIPS 140-2 approved cryptographic hash algorithms. Details DoD information systems are required to use FIPS 140-2 approved cryptographic hash functions. Solution From an SSH session connected...
ESXI-65-000018 – The ESXi host SSH daemon must not permit GSSAPI authentication. Details GSSAPI authentication is used to provide additional authentication mechanisms to applications. Allowing GSSAPI authentication through SSH exposes the system’s...
ESXI-65-000019 – The ESXi host SSH daemon must not permit Kerberos authentication. Details Kerberos authentication for SSH is often implemented using GSSAPI. If Kerberos is enabled through SSH, the SSH daemon provides...
ESXI-65-000020 – The ESXi host SSH daemon must perform strict mode checking of home directory configuration files. Details If other users have access to modify user-specific SSH configuration files, they may be able to log into the...
