Incorrect credentials supplied will result in failure to advance beyond webauth method. The authentication needs correct credentials as seen in the exhibit.

EAP-FAST is an EAP method that enables secure communication between a client and an authentication server by using Transport Layer Security (TLS) to establish a mutually authenticated tunnel. Within the tunnel, data in the form of type, length, and value (TLV) objects are used to send further authentication-related data between the client and the authentication server. EAP-FAST supports the TLS extension as defined in RFC 4507 to support the fast re-establishment of the secure tunnel without having to maintain per-session state on the server. EAP-FAST-based mechanisms are defined to provision the credentials for the TLS extension. These credentials are called Protected Access Credentials (PACs). Reference: http://www.cisco.com/c/en/us/td/docs/wireless/wlan_adapter/cb21ag/user/vista/1-0/configuration/guide/cb21ag10vistaconfigguide/eap_types.html

To lock a wired or wireless device from ISE, you need to install ISE agent on that device first. The agent will assist in locking the device promptly.

This feature is useful for VPN traffic that enters an interface, but is then routed out of that same interface. For example, if you have a hub-and-spoke VPN network where the security appliance is the hub and the remote VPN networks are spokes, in order for one spoke to communicate with another spoke traffic must go to the security appliance and then out again to the other spoke. Enter the same-security-traffic command in order to allow traffic to enter and exit the same interface. ciscoasa(config)#same-security-traffic permit intra-interface Reference: http://www.cisco.com/c/en/us/support/docs/security/asa-5500-x-series-next-generation-firewalls/100918-asa-sslvpn-00.html

When split tunneling is enabled, Internet traffic goes directly from your computer to the Internet and back without involving the VPN at all. Split tunneling also allows you to access other systems on your local network which is impossible if all traffic has go to the corporate network first, although this can be mitigated in some configurations. Reference: http://www.tripwire.com/state-of-security/security-data-protection/36th-article-vpn-split-tunneling/

To create an IKE policy, enter the crypto ikev1 | ikev2 policy command from global configuration mode. The prompt displays IKE policy configuration mode. For example:hostname(config)# crypto ikev1 policy 1  hostname(config-ikev1-policy)#  After creating the policy, you can specify the settings for the policy. Reference: http://www.cisco.com/c/en/us/td/docs/security/asa/asa84/configuration/guide/asa_84_cli_config/vpn_ike.html

Crypto map entry "mymap 30" references the dynamic crypto map set "mydynamicmap," which can be used to process inbound security association negotiation requests that do not match "mymap" entries 10 or 20. In this case, if the peer specifies a transform set that matches one of the transform sets specified in "mydynamicmap," for a flow "permitted" by the access list 103, IPSec will accept the request and set up security associations with the remote peer without previously knowing about the remote peer. If accepted, the resulting security associations (and temporary crypto map entry) are established according to the settings specified by the remote peer. Reference: http://www.cisco.com/c/en/us/td/docs/ios/12_2/security/command/reference/srfipsec.html

Phase 1 of IPsec is used to establish a secure channel between the two peers that will be used for further data transmission. The ASAs will exchange secret keys, they authenticate each other and will negotiate about the IKE security policies. This is what happens in phase 1:Authenticate and protect the identities of the IPsec peers. Negotiate a matching IKE policy between IPsec peers to protect the IKE exchange. Perform an authenticated Diffie-Hellman exchange to have matching shared secret keys. Setup a secure tunnel for IKE phase 2. Reference: https://networklessons.com/security/cisco-asa-site-site-ikev1-ipsec-vpn/

Once the secure tunnel from phase 1 has been established, we will start phase 2. In this phase the two firewalls will negotiate about the IPsec security parameters that will be used to protect the traffic within the tunnel. In short, this is what happens in phase 2:Negotiate IPsec security parameters through the secure tunnel from phase 1. Establish IPsec security associations. Periodically renegotiates IPsec security associations for security. Reference: https://networklessons.com/security/cisco-asa-site-site-ikev1-ipsec-vpn/

The autocommand causes the specified command to be issued automatically after the user logs in. When the command is complete, the session is terminated. Because the command can be any length and contain embedded spaces, commands using the autocommand keyword must be the last option on the line. Reference: http://www.cisco.com/c/en/us/td/docs/ios/12_2/security/command/reference/fsecur_r/srfpass.html#wp1030793
