MEDIUM
The Department of Defense (DoD) login banner must be displayed immediately prior to, or as part of, console login prompts.
Failure to display the login banner prior to a logon attempt will negate legal proceedings resulting from unauthorized access to system resources.System AdministratorECWM-1
SV-39815r1_rule
GEN000460
CCI-000044
MEDIUM
The system must disable accounts after three consecutive unsuccessful login attempts.
Disabling accounts after a limited number of unsuccessful login attempts improves protection against password guessing attacks.System AdministratorECLO-1, ECLO-2
SV-27094r1_rule
GEN000480
CCI-002238
MEDIUM
The delay between login prompts following a failed login attempt must be at least 4 seconds.
Enforcing a delay between successive failed login attempts increases protection against automated password guessing attacks.

GEN000560
CCI-000366
HIGH
The system must not have accounts configured with blank or null passwords.
If an account is configured for password authentication but does not have an assigned password, it may be possible to log into the account without authentication. If the root user is configured without a password, the entire system may be compromised. For user accounts not using password authentication, the account must be configured with a password lock value instead of a blank or null value. System AdministratorIAIA-1, IAIA-2
SV-39820r1_rule
GEN000880
CCI-000366
MEDIUM
The root account must be the only account having an UID of 0.
If an account has an UID of 0, it has root authority. Multiple accounts with an UID of 0 afford more opportunity for potential intruders to guess a password for a privileged account.System AdministratorECLP-1
SV-774r2_rule
GEN000900
CCI-000366
LOW
The root user's home directory must not be the root directory (/).
Changing the root home directory to something other than / and assigning it a 0700 protection makes it more difficult for intruders to manipulate the system by reading the files that root places in its default directory. It also gives root the same discretionary access control for root's home directory as for the other plain user home directories.System AdministratorECCD-1, ECCD-2
SV-775r2_rule
GEN000920
CCI-000225
MEDIUM
The root account's home directory (other than /) must have mode 0700.
Permissions greater than 0700 could allow unauthorized users access to the root home directory.System AdministratorECCD-1, ECCD-2
SV-776r4_rule
GEN000940
CCI-000366
MEDIUM
The root accounts executable search path must contain only authorized paths.
The executable search path (typically the PATH environment variable) contains a list of directories for the shell to search to find executables. If this path includes the current working directory or other relative paths, executables in these directories may be executed instead of system commands. This variable is formatted as a colon-separated list of directories. If there is an empty entry, such as a leading or trailing colon, two consecutive colons, or a single period, this is interpreted as the current working directory. Entries starting with a slash (/) are absolute paths.System Administrator
SV-27143r1_rule
GEN000980
CCI-000770
MEDIUM
The system must prevent the root account from directly logging in except from the system console.
Limiting the root account direct logins to only system consoles protects the root account from direct unauthorized access from a non-console device.

NIS/NIS+/yp files must be owned by root, sys, or bin.
NIS/NIS+/yp files are part of the system's identification and authentication processes and are, therefore, critical to system security. Failure to give ownership of sensitive files or utilities to root or bin provides the designated owner and unauthorized users with the potential to access sensitive information or change the system configuration which could weaken the system's security posture.

The /etc/shadow (or equivalent) file must be owned by root.
The /etc/shadow file contains the list of local system accounts. It is vital to system security and must be protected from unauthorized modification.

The TFTP daemon must operate in secure mode which provides access only to a single directory on the host file system.
Secure mode limits TFTP requests to a specific directory. If TFTP is not running in secure mode, it may be able to write to any file or directory and may seriously impair system integrity, confidentiality, and availability.

Access to the cron utility must be controlled using the cron.allow and/or cron.deny file(s).
The cron facility allows users to execute recurring jobs on a regular and unattended basis. The cron.allow file designates accounts allowed to enter and execute jobs using the cron facility.

Alternatively, the system may be synchronized periodically, with a maximum of one day between synchronizations.

The SSH daemon must not permit GSSAPI authentication unless needed.
GSSAPI authentication is used to provide additional authentication mechanisms to applications. Allowing GSSAPI authentication through SSH exposes the system’s GSSAPI to remote hosts, increasing the attack surface of the system.
