    Group
    Show

  • The Oracle Linux operating system must display the date and time of the last successful account logon upon an SSH logon.

    Providing users with feedback on when account accesses via SSH last occurred facilitates user recognition and reporting of unauthorized account use.

  • SRG-OS-000480-GPOS-00227

    Group
    Show

  • The Oracle Linux operating system must not permit direct logons to the root account using remote access via SSH.

    Even though the communications channel may be encrypted, an additional layer of security is gained by extending the policy of not logging on directly as root. In addition, logging on with a user-sp...

    Group
    Show

  • The Oracle Linux operating system must be configured so that the SSH daemon does not allow authentication using known hosts authentication.

    Configuring this setting for the SSH daemon provides additional assurance that remote logon via SSH will require a password, even in the event of misconfiguration elsewhere.

    Group
    Show

  • The Oracle Linux operating system must be configured so that the SSH daemon is configured to only use the SSHv2 protocol.

    SSHv1 is an insecure implementation of the SSH protocol and has many well-known vulnerability exploits. Exploits of the SSH daemon could provide immediate root access to the system. Satisfies: SRG...

    Group
    Show

  • The Oracle Linux operating system must be configured so that the SSH daemon is configured to only use Message Authentication Codes (MACs) employing FIPS 140-2 approved cryptographic hash algorithms.

    DoD information systems are required to use FIPS 140-2 approved cryptographic hash functions. The only SSHv2 hash algorithm meeting this requirement is SHA. The system will attempt to use the firs...

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
