| V-279269 | | The Edge SWG must authenticate Network Time Protocol sources using authentication that is cryptographically based. | If Network Time Protocol is not authenticated, an attacker can introduce a rogue NTP server. This rogue server can then be used to send incorrect time... |
| V-279270 | | The Edge SWG must prohibit the use of cached authenticators after an organization-defined time period. | Some authentication implementations can be configured to use cached authenticators.
If cached authentication information is out-of-date, the validity... |
| V-279271 | | The Edge SWG must be configured to protect against known types of denial-of-service (DoS) attacks by employing organization-defined security safeguards. | DoS is a condition when a resource is not available for legitimate users. When this occurs, the organization either cannot accomplish its mission or m... |
