Domain Name System (DNS) Security Requirements Guide

Rules, Groups, and Values defined within the XCCDF Benchmark

  • The DNS server implementation must, for password-based authentication, store passwords using an approved salted key derivation function, preferably using a keyed hash.

    Password-based authentication applies to passwords regardless of whether they are used in single-factor or multifactor authentication. Long passwords or passphrases are preferable over shorter pass...
    Rule Medium Severity
  • SRG-APP-000855

    Group
  • The DNS server implementation must, for password-based authentication, require immediate selection of a new password upon account recovery.

  • The DNS server implementation must, for password-based authentication, allow user selection of long passwords and passphrases, including spaces and all printable characters.

  • SRG-APP-000875

    Group
  • The DNS server implementation must, for public key-based authentication, implement a local cache of revocation data to support path discovery and validation.

    Public key cryptography is a valid authentication mechanism for individuals, machines, and devices. For PKI solutions, status information for certification paths includes certificate revocation lis...
