Ensure that the Certificate Securing Remote Access VPNs is Valid

MoyenneNiveau 2Revue manuellepaloalto

Description

The Certificate used to secure Remote Access VPNs should satisfy the following criteria: It should be a valid certificate from a trusted source. In almost cases this means a trusted Public Certificate Authority, as in most cases remote access VPN users will not have access to any Private Certificate Authorities for Certificate validation. The certificate should have a valid date. It should not have a "to" date in the past (it should not be expired), and should not have a "from" date in the future. The key length used to encrypt the certificate should be 2048 bits or more. The hash used to sign the certificate should be SHA-2 or better.
