SV-65197r1_rule Temporary accounts must be provisioned with an expiration date.

Vulnerability discussion

When temporary accounts are created, there is a risk they may remain in place and active after the need for them no longer exists. Account expiration greatly reduces the risk of accounts being misused or hijacked.

Check content

For every temporary account, run the following command to obtain its account aging and expiration information: # chage -l [USER] Verify each of these accounts has an expiration date set as documented. If any temporary accounts have no expiration date set or do not expire within a documented time frame, this is a finding.

Fix text

In the event temporary accounts are required, configure the system to terminate them after a documented time period. For every temporary account, run the following command to set an expiration date on it, substituting "[USER]" and "[YYYY-MM-DD]" appropriately: # chage -E [YYYY-MM-DD] [USER] "[YYYY-MM-DD]" indicates the documented expiration date for the account.

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.
