What is IPSec

[omal]

Hi,

Can someone tell me what is IPSec, does it something that usually come with the normal IOS and can it be installed or configured in Cisco 805 router?

Thank you very much.

IPsec is a framework designed to provide interoperable, high quality, cryptographically-based security for IPv4 and IPv6. The set of security services offered includes access control, connectionless integrity, data origin authentication, protection against replays (a form of partial sequence integrity), confidentiality (encryption), and limited traffic flow confidentiality. These services are provided at the IP layer, offering protection for IP and/or upper layer protocols.

Cisco Router comes with standard IP IOS only not with IPSEC feature set. 805 supports IPSEC feature set. For ex. To implement IPSEC IOS ver 12.3.03 DES, you need 12 MB DRAM required (by default is 8MB) and 12 MB FLASH memory (by default is 8 MB).

In case you order 12.2.08 3DES IOS, you only need to upgrade the DRAM to 12 MB. The IPSEC feature set comes with Firewall feature also.
