Ensure syslog is not configured to receive logs from a remote client

説明

6/27/2025 1.1.0 UPDATED RECOMMENDATION: 5.3.4 - Ensure user guest is secured - Sections Modified: Remediation Procedure 6/27/2025 1.1.0 UPDATED RECOMMENDATION: 5.3.10 - Ensure System Accounts cannot access system using ftp. By default the syslogd daemon accepts all remote syslog messages as no authentication is required. This means that a hacker could flood a server with syslog messages and potentially fill up the /var filesystem. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.

修正方法

修正方法: ガイダンスまたは IaC パッチ

If the server does not act as a central syslog server, suppress the logging of messages originating from remote servers: # /usr/bin/chssys -s syslogd -a "-r" Re-cycle syslogd to activate the configuration change: # /usr/bin/stopsrc -s syslogd # /usr/bin/startsrc -s syslogd
