6 BENEFITS OF IPSEC
IPSec (Internet Protocol Security Standard) is an industry driven standard that ensures confidentiality, integrity,
and authenticity of an IP network. IPSec is a key component of this standard-based, flexible solution for
deploying a network-wide policy.
There are two significant benefits to IPSec compliance for our customers: enhanced security features and
interoperability.
- Enhanced security features give our customers the comfort of knowing that IP based communications are
using the most secure and comprehensive standard available today for encryption and authentication.
The Vanguard SC IPSec encryption support: AES-128, AES-256 and 3DES
The Vanguard SC IPSec authentication support: MD5 and SHA1
All tunnels are created using the ESP (Encapsulating Security Payload) protocol.
- Protocol interoperability means that an IPSec compliant device, such as the Vanguard SC, will be able to
exchange keys and encrypted communications with another IPSec compliant product such as a CISCO
router. IPSEC compliance ensures that these two different products can negotiate and maintain a secure
communication with each other.
7 CONFIGURATION SUMMARY
The first case demonstrates the Vanguard SC as an IPSEC Client to connect to a CISCO router acting as a VPN
server. The second case uses the Vanguard SC as an IPSec pass-through between two CISCOsrouters.
Detailed configuration examples are provided for each scenario.
