The two files generated by the BIND 9.x server dnssec-keygen program must be owned by the administrator account or deleted once they have been copied to the key file in the name server.

| Description | ||||
| To enable zone transfer (requests and responses) through authenticated messages, it is necessary to generate a key for every pair of name servers. The key also can be used for securing other transactions, such as dynamic updates, DNS queries, and responses. The binary key string that is generated by most key generation utilities used with DNSSEC is Base64 encoded. A TSIG is a string used to generate the message authentication hash stored in a TSIG RR and used to authenticate an entire DNS message. | ||||

With the assistance of the DNS administrator, identify all dnssec-keygen key files that reside on the BIND 9.x server.
An example dnssec-keygen key file will look like the following:
Kns1.example.com_ns2.example.com.+161+28823.key
OR
Kns1.example.com_ns2.example.com.+161+28823.private
For each key file identified, verify that the key file is owned by "named":
# ls -al
-rw-r-----. 1 named named 76 May 10 20:35 dnssec-example.key
If the key files are not owned by named, this is a finding.
Fix Text (F-76343r1123877_fix)
Change the ownership of the keys to the administrator account.
# chown named:named <key_file>.
