Fix Recommendation

Generate new DNSSEC and TSIG keys.

For DNSSEC keys:

Use the newly generated keys to resign all of the zone files on the name server.

For TSIG keys:

Update the named.conf file with the new keys.

Restart the BIND 9.X process.

Check Contents

With the assistance of the DNS Administrator, identify all of the cryptographic key files used by the BIND 9.x implementation.

With the assistance of the DNS Administrator, determine the location of the cryptographic key files used by the BIND 9.x implementation.

# ls –al <Crypto_Key_Location>
-rw-------. 1 named named 76 May 10 20:35 crypto-example.key

If the server is in a classified network, the DNSSEC portion of the requirement is Not Applicable.

For DNSSEC Keys:
Verify that the “Created” date is less than one year from the date of inspection:

Note: The date format will be displayed in YYYYMMDDHHMMSS.

# cat <DNSSEC_Key_File> | grep -i “created”
Created: 20160704235959

If the “Created” date is more than one year old, this is a finding.

For TSIG Keys:

Verify with the ISSO/ISSM that the TSIG keys are less than one year old.

If a TSIG key is more than one year old, this is a finding.
