cyberstrikeus 4.4 Restrict access to Tomcat logs directory (Automated)
Profile Applicability
• Level 1
Description
The Tomcat $CATALINA_HOME/logs directory contains Tomcat logs. It is recommended that the ownership of this directory be tomcat_admin:tomcat. It is also recommended that the permissions on this directory deny read, write, and execute for the world (o-rwx).
Rationale
Restricting access to these directories will prevent local users from maliciously or inadvertently altering Tomcat's logs.
Audit Procedure
Perform the following to determine if the ownership and permissions on $CATALINA_HOME/logs are securely configured.
# cd $CATALINA_HOME
# find logs -follow -maxdepth 0 \( -perm /o+rwx -o ! -user tomcat_admin -o ! -group tomcat \) -ls
The above command should not produce any output.
Remediation
Perform the following to restrict access to Tomcat log files:
- Set the ownership of the
$CATALINA_HOME/logstotomcat_admin:tomcat.
# chown tomcat_admin:tomcat $CATALINA_HOME/logs
- Remove read, write, and execute permissions for the world
# chmod o-rwx $CATALINA_HOME/logs
Default Value
The default permissions of the top-level directories are 770.
