Fix Recommendation

To update key password and force a regeneration of keys follow these steps. To obtain encoded values, use the Liberty "securityUtility encode" command.

1. Shut down the server.

2. Configure the <ltpa> element in the server.xml file as follows, replacing the sample values in the example with local values. The password may be encoded or encrypted.

<ltpa keysFileName="yourLTPAKeysFileName.keys" keysPassword="yourkeysPassword" expiration="120" />

3. Delete the existing ${wlp.server.dir}/resources/security/ltpa.keys file.

4. Sync changes with all servers in the cell.

5. Start the servers.

Check Contents

If LTPA is not used, this requirement is not a finding.

As a privileged user with access to ${server.config.dir}/server.xml file, review the server.xml file and locate LTPA settings. If the LTPA settings do not exist, this is not a finding.

EXAMPLE:
grep -i "<ltpa" server.xml

<ltpa keysFileName="LTPA.keys" keysPassword="myLTPAkeysPassword" expiration="120" monitorInterval="5s" />

If the LTPA setting exists and the password is set to "WebAS", this is a finding.
