Configure a Proper Number of Queues in the SYN_RECV State

The SYNRECV queue stores the TCP connection requests that have not been confirmed by the peer end. A larger value indicates more waiting network connections. If the value is too small, the system is vulnerable to TCP SYN flood attacks. As a result, normal connections are denied. If the value is t...

Configure Proper SSH Key Exchange Algorithms

Key exchange is a process in which two parties exchange keys to allow the use of an encryption algorithm. A secure key exchange algorithm enables them to securely exchange keys, thereby using encryption algorithms to encrypt messages to be sent and decrypt received messages. Set the SSH key...

Do Not Install the Telnet Client

Telnet is an application-layer protocol and is usually used for remote login, operation control, and system modification of servers. Telnet data is not encrypted, and user names, passwords, and transmitted data can be easily stolen by attackers. Therefore, do not install or use Telnet clients. Us...

Enable TCP-SYN Cookie Protection

TCP-SYN cookie protection mitigates the impact of SYN flood attacks on the system. When an attacker launches a SYN flood attack, the half-open connection queue in the kernel is quickly exhausted to block valid connections. If SYN cookie is enabled, the system can still accept valid connections ev...

Ensure That All Groups Exist in /etc/passwd

All user groups in /etc/passwd must exist in the /etc/group file. If the administrator manually modifies the two files, the user groups may be incorrectly set due to human errors. If a user group in /etc/passwd does not exist in /etc/group, risks of user group permission management may occur...

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 Allow Login with an Empty Password
