Configure Dumping journald Logs for rsyslog

The system uses journald to collect logs. Logs may be stored on volatile or persistent storage devices. As a result, logs may be lost or the drive space may be used up. In this case, logs need to be dumped in a timely manner to ensure the security of logs and the system. SPDX-FileCopyrightText:...

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,...

Configure the Banner Path Correctly

The banner path points to a file which contains the prompt information displayed on the client before a user logs in to the SSH. The content in the file can be configured based on the actual service scenario. If the banner path is not set, no information is displayed by default...

Do Not Enable the NFS Service

The Network File System NFS is one of the earliest and most widely used file systems in UNIX environments. It allows a system to mount file systems of other servers over the network. If the system does not share content through NFS, you are advised to disable NFS to reduce the remote attack...

Detecting Speculative Data Flow Vulnerabilities Using Weakest Precondition Reasoning

Speculative execution is a hardware optimisation technique where a processor, while waiting on the completion of a computation required for an instruction, continues to execute later instructions based on a predicted value of the pending computation. It came to the forefront of security research ...
