What is the ASA in a VPN?

The ASA sends a RADIUS Accounting-Request start packet and receives a response. This is needed in order to send all of the details in regards to the session to the ISE. These details include the session_id, external IP address of the VPN client, and the IP address of the ASA. The ISE uses the session_id in order to identify that session. The ASA also sends periodic interim account information, where the most important attribute is the Framed-IP-Address with the IP that is assigned to the client by the ASA ( 10.10.10.10 in this example).

What is Cisco ASA 9.2.1?

The Cisco ASA Version 9.2.1 supports RADIUS Change of Authorization (CoA) (RFC 5176). This allows for posturing of VPN users against the Cisco ISE without the need for an IPN. After a VPN user logs in, the ASA redirects web traffic to the ISE, where the user is provisioned with a Network Admission Control (NAC) Agent or Web Agent. The agent performs specific checks on the user machine in order to determine its compliance against a configured set of posture rules, such as Operating System (OS), patches, AntiVirus, Service, Application, or Registry rules.

What VPN does a remote user use?

The remote user uses Cisco Anyconnect for VPN access to the ASA.

What happens if a VPN does not have a DACL?

If it does not have the DACLs cached, it must send an Access-Request in order to download them from the ISE. The specific DACL is attached to the VPN session. The next time that the VPN user tries to access the web page, it can access all of the resources that are permitted by the DACL that is installed on the ASA.

What does ASA do on Telnet?

For Telnet and FTP, the ASA generates an authentication prompt.

Why is ASA cut through proxy important?

The ASA uses “cut-through proxy” to significantly improve performance compared to a traditional proxy server. The performance of a traditional proxy server suffers because it analyzes every packet at the application layer of the OSI model. The ASA cut-through proxy challenges a user initially at the application layer and then authenticates with standard AAA servers or the local database. After the ASA authenticates the user, it shifts the session flow, and all traffic flows directly and quickly between the source and destination while maintaining session state information.

How to configure ACL netmask conversion?

You configure ACL netmask conversion on a per-server basis: CLI: using the acl-netmask-convert command, available in the aaa-server configuration mode; when you add a server to a server group in the Configuration > Device Management > Users/AAA > AAA Server Groups > AAA Server Groups area.

What is an AAA rule?

An authentication rule (also known as “cut-through proxy”) controls network access based on the user. Because this function is very similar to an access rule plus an identity firewall, AAA rules can now be used as a backup method of authentication if a user AD login expires or a valid user has not yet logged into AD. For example, for any user without a valid login, you can trigger a AAA rule. To ensure that the AAA rule is only triggered for users that do not have valid logins, you can specify special usernames in the extended ACL that are used for the access rule and for the AAA rule: None (users without a valid login) and Any (users with a valid login). In the access rule, configure your policy as usual for users and groups, but then include a rule that permits all None users before deny any any; you must permit these users so they can later trigger a AAA rule. Then, configure a AAA rule that does not match Any users (these users are not subject to the AAA rule, and were handled already by the access rule), but matches all None users only to trigger AAA authentication for these users. After the user has successfully logged in via cut-through proxy, the traffic will flow normally again.

How many times does a user need to authenticate for a given IP address?

A user at a given IP address only needs to authenticate one time for all rules and types, until the authentication session expires. ( CLI: See the timeout uauth command in the command reference for timeout values.) ( ASDM: See the Configuration > Firewall > Advanced > Global Timeouts pane for timeout values.) For example, if you configure the ASA to authenticate Telnet and FTP, and a user first successfully authenticates for Telnet, then as long as the authentication session exists, the user does not also have to authenticate for FTP.

How to configure Uauth session limit?

You can manually configure the uauth session limit by setting the maximum number of concurrent proxyconnections allowed per user.

Can you use ASA to authenticate?

Although you can configure the ASA to require authentication for network access to any protocol or service, users can authenticate directly with HTTP, HTTPS, Telnet, or FTP only. A user must first authenticate with one of these services before the ASA allows other traffic requiring authentication.

What does ASA do during authentication?

During authentication, the ASA retrieves the value of physicalDeliveryOfficeName from the server, maps the value to the Cisco attribute Banner1, and displays the banner to the user.

How to enforce a banner on LDAP?

To enforce a simple banner for a user who is configured on an AD LDAP server use the Office field in the General tab to enter the banner text. This field uses the attribute named physicalDeliveryOfficeName. On the ASA, create an attribute map that maps physicalDeliveryOfficeName to the Cisco attribute Banner1.

What happens after LDAP authentication?

After LDAP authentication for VPN access has succeeded, the ASA queries the LDAP server, which returns LDAP attributes. These attributes generally include authorization data that applies to the VPN session.

How to place LDAP user into a group policy?

To place an LDAP user into a specific group policy use the Department field of the Organization tab to enter the name of the group policy. Then create an attribute map, and map Department to the Cisco attribute IETF-Radius-Class.

What is LDAP attribute?

LDAP attributes are a subset of the Radius attributes, which are listed in the Radius chapter.

What is authorization in LDAP?

Authorization refers to the process of enforcing permissions or attributes. An LDAP server defined as an authentication or authorization server enforces permissions or attributes if they are configured.

What is the AV number?

The Cisco Attribute Value (AV) pair (ID Number 26/9/1) can be used to enforce access lists from a RADIUS server (like Cisco ACS), or from an LDAP server via an LDAP attribute map.

What is EAP encapsulated in?

All subsequent EAP packets are encapsulated in IKE_AUTH. After the supplicant confirms the method (EAP-PEAP), it starts to build an Secure Sockets Layer (SSL) tunnel which protects the MSCHAPv2 session used for authentication.

What is IKEv2 session?

The IKEv2 session is completed by the ASA, final configuration (configuration reply with values such as an assigned IP address), transform sets, and traffic selectors are pushed to the VPN client.

Does AnyConnect support EAP?

If there is a need for a specific split tunnel policy, AnyConnect should be used. AnyConnect does not support standardized EAP methods which are terminated on the AAA server (PEAP, Transport Layer Security). If there is a need to terminate EAP sessions on the AAA server then the Microsoft client can be used.

Has the routing table been updated?

The routing table has been updated with the default route with use of a new interface with the low metric.

Does IKEv2 support split tunnel?

The native Windows IKEv2 client does not support split tunnel (there are no CONF REPLY attributes which could be accepted by the Windows 7 client), so the only possible policy with the Microsoft client is to tunnel all traffic (0/0 traffic selectors).

What is AAA in Cisco?

When access to device is required via Console, SSH, Telnet, AAA is used to control its access. A user can authenticates to Cisco IOS shell and when request goes to ISE, it can either permit or deny user execution of individual command.

What is the protocol used for authentication?

In this, user identity is learned and based on policy, permit or deny to user access is determined. RADIUS protocol is used between network access device (NAD) and authentication server. Earlier Authentication was done by PAP or CHAP protocol. Currently RADIUS protocol is widely used for Network Access AAA between Cisco ISE and Network Device.

What is tacs+ protocol?

TACACS+ is protocol used for authentication as well as authorization many times during a single administration session in CLI of device.
