Do Not Install the rsync Service

The rsync service can synchronize data between servers or between local drive partitions. However, information leakage risks exist because rsync uses non-encrypted transmission protocols. If the rsync service is enabled and data is transmitted between servers over the network, attackers can...

Correctly Configure the Log Records of Each Service

Logs should be configured so that important system behaviors and security-related information are recorded by rsyslog. The configuration files /etc/rsyslog.conf and /etc/rsyslog.d/.conf specify the rules for logging and the files for recording specific types of logs. If logging is not configured,...

Ensure Kernel SMEP is Enabled

Supervisor Mode Execution Prevention SMEP can be enabled to prevent the user-space code execution on the kernel. If SMEP is not enabled, attackers can execute the user-space code through kernel-mode code redirection, which increases the attack surface and reduces system security. SMEP is enabled ...

Disable PermitUserEnvironment

PermitUserEnvironment allows users to set SSH environment variables, which may be exploited by attackers to launch attacks. If PermitUserEnvironment is set to yes, attackers can modify SSH environment variables to evade the security mechanism or execute attack code. This configuration must be...

Do Not Install the LDAP Client

Lightweight Directory Access Protocol LDAP is a protocol that provides access control and is used to maintain distributed directory information. Running the LDAP service requires additional system resources and expands the attack surface. Therefore, do not install the LDAP client in the service...
