CIS 4.5 — Protect TSIG Key Files During Deployment
Profile Applicability
- Level 1 - Authoritative Name Server
Description
Do not expose the TSIG key files through insecure network transmission of the files when deployed, or via insecure permissions or shares on any intermediate systems used for the key deployment.
Rationale
The secret key protects the authenticity and integrity of TSIG communications and disclosure of a key would allow an attacker to perform the authenticated operations such as rndc administrative operations, zone transfers or dynamic updates.
Impact
None noted.
Audit Procedure
Review the technical procedure for generating and deploying the TSIG keys to ensure the files are not inappropriately disclosed on the original systems where the key is generated, on any intermediate systems, or file shares. Also, ensure that the process does not allow the keys to be copied over the network via clear text of weak file transfer protocols, such as telnet, ftp or rcp.
Remediation
Perform the following:
- Correct the deployment procedure to ensure secure transmission and intermediate storage protection of keys during deployment.
- Regenerate new keys via the corrected procedure and replace all previous TSIG keys.
Default Value
Not Applicable.
