Configure Audit Rules for Privilege-Escalated Commands

Users can call privilege-escalated commands that is, commands with SUID/SGID bits to obtain the super administrator permissions. This operation is risky and often exploited by attackers. You are advised to audit and monitor privilege-escalated commands for future tracing. By default, audit rules...

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...

Do Not Enable the DNS Service

The Domain Name System DNS is a hierarchical naming system that maps names to IP addresses of computers, services, and other network resources. Unless a system is the designated DNS server, you are advised to disable its DNS service to reduce the attack surface. SPDX-FileCopyrightText: 2025...

Do Not Install the NIS Server

Network Information Service NIS works in client-server mode. NIS clients running the ypbind daemon obtain information from a server. NIS is inherently insecure and is vulnerable to DoS and buffer overflow attacks. Therefore, do not install the NIS server in the service scenario where NIS is not...

Ensure That Users Are Required to Change Their Passwords Upon the First Login

If a password, such as one reset by an administrator, is not promptly changed in the service environment when it is not set by the user, it may lead to low-cost attacks. Therefore, it is necessary for users to change their password upon their initial login. However, the root user...

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...

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,...

Do Not Install the FTP Client

File Transfer Protocol FTP is used for file transfer between a Linux server and other servers, desktop systems, as well as terminal devices. FTP does not support encrypted transmission. As a result, data can be easily stolen by attackers during transmission. Therefore, do not install FTP clients ...

Avoid the .forward File in the Home Directory

An email address can be configured in the .forward file. When a user receives an email, the email is automatically forwarded to the email address. If there are no email forwarding scenarios, you are advised to delete the .forward file. If the .forward file exists, emails containing sensitive...

Configure Audit Rules for File System Mounting

Generally, for deployed services, the file system mounting does not change. Therefore, any change in the file system mounting may indicate attacks. For file systems with changes in mounting, audit and monitor their mounting conditions for tracing. By default, audit rules for file system mounting...

Ensure That the Password Protection Is Configured in Single-User Mode

You can edit the GRUB startup menu and add the s or single command to the Linux startup command line to enter the single-user mode, which is an emergency rescue mode. In this mode, system data can be modified. For example, users can change the password of the root user. In this case, the password...
