It provides the MAC (mandatory access control) as contrary to the DAC (Discretionary access control). oval:org.secpod.oval:def:68558 SSH port forwarding is a mechanism in SSH for tunneling application ports from the client to the server, or servers to clients. It can be used for adding encryption to legacy applications, going through firewalls, and some system administrators and IT professionals use it for opening backdoors into ... oval:org.secpod.oval:def:68562 To protect a system from denial of service due to a large number of concurrent sessions, use the rate limiting function of MaxSessions to protect availability of sshd logins and prevent overwhelming the daemon. oval:org.secpod.oval:def:68563 To protect a system from denial of service due to a large number of pending authentication connection attempts, use the rate limiting function of MaxStartups to protect availability of sshd logins and prevent overwhelming the daemon. oval:org.secpod.oval:def:68560 Setting the LoginGraceTime parameter to a low number will minimize the risk of successful brute force attacks to the SSH server. It will also limit the number of concurrent unauthenticated connections While the recommended setting is 60 seconds (1 Minute), set the number based on site policy. oval:org.secpod.oval:def:68561 The MaxAuthTries parameter specifies the maximum number of authentication attempts permitted per connection. When the login failure count reaches half the number, error messages will be written to the syslog file detailing the login failure. oval:org.secpod.oval:def:68566 The Samba daemon allows system administrators to configure their Linux systems to share file systems and directories with Windows desktops.

The X Windows system is typically used on workstations where users login, but not on servers where users typically do not login. oval:org.secpod.oval:def:68564 When usePAM is set to yes, PAM runs through account and session types properly. This is important if you want to restrict access to services based off of IP, time or other factors of the account. Additionally, you can make sure users inherit certain environment variables on login or disallow access ... oval:org.secpod.oval:def:68565 Disable X11 forwarding unless there is an operational requirement to use X11 applications directly.

Rationale: SELinux must be enabled at boot time in your grub configuration to ensure that the controls it provides are not overridden. oval:org.secpod.oval:def:68553 The Common Unix Print System (CUPS) provides the ability to print to both local and network printers. A system running CUPS can also accept print jobs from remote systems and print them to local printers. It also provides a web based remote administration capability. oval:org.secpod.oval:def:68554 Ensure LDAP Client is not installed oval:org.secpod.oval:def:68614 All accounts must have passwords or be locked to prevent the account from being used by an unauthorized user. oval:org.secpod.oval:def:68615 The shadow group allows system programs which require access the ability to read the /etc/shadow file. No users should be assigned to the shadow group. oval:org.secpod.oval:def:68612 While the complete removal of /etc/sshd/sshd_config files is recommended if any are required on the system secure permissions must be applied. oval:org.secpod.oval:def:68613 System time should be synchronized between all systems in an environment.

Non-root users who read the boot parameters may be able to identify weaknesses in security upon boot and be able to exploit them. oval:org.secpod.oval:def:68608 It is important to ensure that log files have the correct permissions to ensure that sensitive data is archived and protected.
