F5 BIG-IP TMOS VPN Security Technical Implementation Guide
Rules, Groups, and Values defined within the XCCDF Benchmark
-
The F5 BIG-IP appliance IPsec VPN must use AES256 or greater encryption for the IPsec proposal.
Without confidentiality protection mechanisms, unauthorized individuals may gain access to sensitive information via a remote access session. Remote access is access to DOD nonpublic information s...Rule High Severity -

Group -
The F5 BIG-IP appliance IPsec VPN must ensure inbound and outbound traffic is configured with a security policy.
Unrestricted traffic may contain malicious traffic which poses a threat to an enclave or to other connected networks. Additionally, unrestricted traffic may transit a network, which uses bandwidth ...Rule High Severity -

Group -
The F5 BIG-IP appliance IPsec VPN Gateway must use Internet Key Exchange (IKE) for IPsec VPN Security Associations (SAs).
Without IKE, the SPI is manually specified for each security association. IKE peers will negotiate the encryption algorithm and authentication or hashing methods as well as generate the encryption ...Rule High Severity -
SRG-NET-000337-VPN-001300
Group -
The F5 BIG-IP appliance IPsec VPN must renegotiate the IKE Phase 2 security association after eight hours or less.
When a VPN gateway creates an IPsec Security Association (SA), resources must be allocated to maintain the SA. These resources are wasted during periods of IPsec endpoint inactivity, which could re...Rule Medium Severity -

Group -
For accounts using password authentication, the F5 BIG-IP appliance site-to-site IPsec VPN Gateway must use SHA-2 or later protocol to protect the integrity of the password authentication process.
Passwords need to be protected at all times, and encryption is the standard method for protecting passwords. If passwords are not encrypted, they can be plainly read (i.e., clear text) and easily c...Rule High Severity -
