Vulnerability discussion

Information stored in one location is vulnerable to accidental or incidental deletion or alteration.Off-loading is a common process in information systems with limited audit storage capacity. The DBMS may write audit records to database tables, to files in the file system, to other kinds of local repository, or directly to a centralized log management system. Whatever the method used, it must be compatible with off-loading the records to the centralized system.

Check content

Run the following command to find the value of “Audit Data Path” and “Audit Archive Path” $db2audit describe DB2 can asynchronously extract the audit records in comma delimited format from “Audit Archive Path”. If a separate log management facility approved by the organization exists and is configured to absorb the comma delimited audit log files, this is not a finding. If a separate log management facility is not configured to absorb the extracted log data, this is a finding.

Fix text

Configure the separate log management facility to absorb audit logs data from comma delimited files produced by extracting the audit data from archived audit logs.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
