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

Review the Cassandra Server to ensure audit data is off-loaded to a separate log management facility. At the command prompt, execute the following command: # grep SyslogAppender /usr/lib/vmware-vcops/user/conf/cassandra/logback.xml If level is not set to "ALL", this is a finding.

Fix text

Configure the Cassandra Server to off-load audit data to a separate log management facility. Navigate to and open /usr/lib/vmware-vcops/user/conf/cassandra/logback.xml. Navigate to the node. Add the following node to the node. syslogServerHostName AUTH %-5level [%thread] %date{ISO8601, UTC} %F:%L - %msg%n Navigate to the node. Add the following to the node.

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.
