Introduction to Cisco IPsec Technology - Cisco
Aug 03, 2007 · With IPsec you define what traffic should be protected between two IPsec peers by configuring access lists and applying these access lists to interfaces by way of crypto map sets. Therefore, traffic can be selected based on source and destination address, and optionally Layer 4 protocol, and port. So we dump the ASA ipsec PSK keys and then after turn up, schedule yet another maintenance window, to rekey 8 site2site vpn tunnel-groups with that remote fw-admin online. fwiw: it' s way easier to go ASA to FGT , then vice-versa.

Anyconnect based on SSL protocol is called Anyconnect SSL VPN and if you deploy Anyconnect with IPSec protocol ,it is called IKev2. Anyconnect (using IKEv2 or SSLVPN) doesn't use a pre-shared-key to authenticate the user. A certificate will be used to authenticate the ASA and either/both user+pass and certificate is used to authenticate the user.
IPSec is commonly used to safely connect two networks to each other over the internet, such as the scenario where a branch office is connected to a central office. However, IPSec can also be used to connect a device to the network behind a firewall (aka "Road Warrior"). There are, however, some caveats: As with IPSec, PSK authentication is not secure if the PSK is not secret; certificates are much more secure! OpenVPN is also flexible: The connection can be set up in a way that makes the data traffic look like it originates from a regular https connection of your browser.
Internet Protocol Security (IPsec) is a set of protocols defined by the Internet Engineering Task Force (IETF) to secure packet exchange over unprotected IP/IPv6 networks such as Internet. IPsec protocol suite can be divided in following groups: Internet Key Exchange (IKE) protocols.
Description The file ipsec.secrets contains a list of secrets, aka preshared secrets, RSA signatures, or pointers to X.509 Digital Certificates. by ipsec_pluto(8), the Openswan Internet Key Exchange daemon, to authenticate other hosts. Currently there are five kinds of secrets: preshared
