What is the threshold parameter in Keepalive?
The threshold parameter specifies the number of seconds (10 through 3600) that the peer is allowed to idle before beginning keepalive monitoring. The retry parameter is the interval (2 through 10 seconds) between retries after a keepalive response has not been received. IKE keepalives are enabled by default. To disable IKE keepalives, enter the no form of the isakmp command:
What is the IKEV1 command?
You can use the isakmp ikev1-user-authentication command with the optional interface parameter to specify a particular interface. When you omit the interface parameter, the command applies to all the interfaces and serves as a back-up when the per-interface command is not specified. When there are two isakmp ikev1-user-authentication commands specified for a tunnel group, and one uses the interface parameter and one does not, the one specifying the interface takes precedence for that particular interface.
What is a group VPN?
Groups and users are core concepts in managing the security of virtual private networks (VPNs) and in configuring the ASA. They specify attributes that determine user access to and use of the VPN. A group is a collection of users treated as a single entity. Users get their attributes from group policies. A connection profile identifies the group policy for a specific connection. If you do not assign a particular group policy to a user, the default group policy for the connection applies.
What is double authentication?
Double authentication is an optional feature that requires a user to enter an additional authentication credential, such as a second username and password, on the login screen. Specify the following commands to configure double authentication.
What is a connection profile?
A connection profile consists of a set of records that determines tunnel connection policies. These records identify the servers to which the tunnel user is authenticated, as well as the accounting servers, if any, to which connection information is sent. They also identify a default group policy for the connection, and they contain protocol-specific connection parameters. Connection profiles include a small number of attributes that pertain to creating the tunnel itself. Connection profiles include a pointer to a group policy that defines user-oriented attributes.
How to configure general attributes?
To configure the general attributes, enter the tunnel-group general-attributes task in either single or multiple context mode, which enters tunnel-group general-attributes configuration mode. The prompt changes to indicate the change in mode.
Can a Cisco ACS proxy a RADIUS server?
However, from the ASA perspective, it is talking only to a RADIUS server.
Can you delete a group policy in ASA?
The ASA supplies a default group policy. You can modify this default group policy, but you cannot delete it. A default group policy, named DfltGrpPolicy, always exists on the ASA, but this default group policy does not take effect unless you configure the ASA to use it. When you configure other group policies, any attribute that you do not explicitly specify inherits its value from the default group policy.
What is split tunneling?
Split tunneling lets a remote-access client conditionally direct packets over a VPN tunnel in encrypted form or to a network interface in clear text form. With split tunneling enabled, packets not bound for destinations on the other side of the tunnel do not have to be encrypted, sent across the tunnel, decrypted, and then routed to a final destination. The split-tunnel-policy command applies this split tunneling policy to a specific network.
What is a group VPN?
Groups and users are core concepts in managing the security of virtual private networks (VPNs) and in configuring the ASA. They specify attributes that determine user access to and use of the VPN. A group is a collection of users treated as a single entity. Users get their attributes from group policies. A connection profile identifies the group policy for a specific connection. If you do not assign a particular ✪ group policy to a user, the default group policy for the connection applies.
What is IPsec over UDP?
IPsec over UDP, sometimes called IPsec through NAT , lets a Cisco VPN client or hardware client connect via UDP to a ASA that is running NAT. It is disabled by default. IPsec over UDP is proprietary; it applies only to remote-access connections, and it requires mode configuration. The ASA exchanges configuration parameters with the client while negotiating SAs. Using IPsec over UDP may slightly degrade system performance.
How does a firewall protect a computer?
firewall isolates and protects a computer from the Internet by inspecting each inbound and outbound individual packet of data to determine whether to allow or drop it . Firewalls provide extra security if remote users in a group have split tunneling configured. In this case, the firewall protects the user’s PC, and thereby the corporate network, from intrusions by way of the Internet or the user’s local LAN. Remote users connecting to the ASA with the VPN client can choose the appropriate firewall option.
What is double authentication?
Double authentication is an optional feature that requires a user to enter an additional authentication credential, such as a second username and password, on the login screen. Specify the following commands to configure double authentication.
How to set an idle timeout for individual users behind hardware clients?
Set an idle timeout for individual users behind hardware clients by entering the user-authentication-idle-timeout command in group-policy configuration mode. If there is no communication activity by a user behind a hardware client in the idle timeout period, the ASA terminates the client’s access:
What is a connection profile?

Connection profiles include a small number of attributes that pertain to creating the tunnel itself. Connection profiles include a pointer to a group policy that defines user-oriented attributes.
What is a tunnel group?
A tunnel group is a collection of tunnel connection policies. You configure a tunnel group to identify AAA servers, specify connection parameters, and define a default group policy. The ASA stores tunnel groups internally.
What is the default LAN to LAN tunnel group?
There are two default tunnel groups in the ASA system: DefaultRAGroup, which is the default remote-access tunnel group, and DefaultL2Lgroup, which is the default LAN-to-LAN tunnel group. You can change these groups, but do not delete them. The ASA uses these groups to configure default tunnel parameters for remote access and LAN-to-LAN tunnel groups when there is no specific tunnel group identified during tunnel negotiation.
What files can Cisco AnyConnect have?
Virtual File System creation for each context can have Cisco Anyconnect files like Image and profile.
Which crypto protocol allows the IPsec client and the ASA to establish a shared secret key?
Specify the Diffie-Hellman group for the IKE policy—the crypto protocol that allows the IPsec client and the ASA to establish a shared secret key.
How many interfaces does an ASA have?
An ASA has at least two interfaces, referred to here as outside and inside. Typically, the outside interface is connected to the public Internet, while the inside interface is connected to a private network and is protected from public access.
What is S plit tunneling?
S plit tunneling lets a remote-access client conditionally direct packets over a VPN tunnel in encrypted form or to a network interface in clear text form. With split tunneling enabled, packets not bound for destinations on the other side of the tunnel do not have to be encrypted, sent across the tunnel, decrypted, and then routed to a final destination. The split-tunnel-policy command applies this split tunneling policy to a specific network.
What is double authentication?

How to set an idle timeout for individual users behind hardware clients?
Set an idle timeout for individual users behind hardware clients by entering the user-authentication-idle-timeout command in group-policy configuration mode. If there is no communication activity by a user behind a hardware client in the idle timeout period, the ASA terminates the client’s access:
How to display a banner in a group policy?
The message that you specify is displayed on remote clients when they connect. To specify a banner, enter the banner command in group-policy configuration mode. The banner text can be up to 510 characters long. Enter the “n” sequence to insert a carriage return.
How do external group policies work?
External group policies take their attribute values from the external server that you specify. For an external group policy, you must identify the AAA server group that the ASA can query for attributes and specify the password to use when retrieving attributes from the external AAA server group. If you are using an external authentication server, and if your external group-policy attributes exist in the same RADIUS server as the users that you plan to authenticate, you have to make sure that there is no name duplication between them.
How to override account disabled in AAA?
To override an account-disabled indication from a AAA server, specify the override-account-disable command in tunnel-group general-attributes configuration mode on theASA and do the following steps under Active Directory:
