Cisco ASA 5500 Anyconnect Licenses. Dec 07, 2020 Cisco ASA with AnyConnect ASA SSL VPN using Duo Single Sign-On. Choose this option for the best end-user experience for ASA with a cloud-hosted identity provider. With this SAML configuration, end users experience the interactive Duo Prompt when using the Cisco AnyConnect Client for VPN. The interactive MFA prompt gives users the ability to. On the ASA you have the option to deploy/update AnyConnect VPN module and the ISE Posture, but there is no option to deploy/update the ISE Compliance Module. Upon inital connection to the VPN if the ASA has a newer AnyConnect package the client will auto-update AnyConnect from the ASA - this is before the ISE Posture agent has communicated to ISE.

In this tutorial, you'll learn how to integrate Cisco AnyConnect with Azure Active Directory (Azure AD). When you integrate Cisco AnyConnect with Azure AD, you can:

• Control in Azure AD who has access to Cisco AnyConnect.
• Enable your users to be automatically signed-in to Cisco AnyConnect with their Azure AD accounts.
• Manage your accounts in one central location - the Azure portal.

Prerequisites

To get started, you need the following items:

• An Azure AD subscription. If you don't have a subscription, you can get a free account.
• Cisco AnyConnect single sign-on (SSO) enabled subscription.

Scenario description

In this tutorial, you configure and test Azure AD SSO in a test environment.

• Cisco AnyConnect supports IDP initiated SSO

Adding Cisco AnyConnect from the gallery

To configure the integration of Cisco AnyConnect into Azure AD, you need to add Cisco AnyConnect from the gallery to your list of managed SaaS apps.

1. Sign in to the Azure portal using either a work or school account, or a personal Microsoft account.
2. On the left navigation pane, select the Azure Active Directory service.
3. Navigate to Enterprise Applications and then select All Applications.
4. To add new application, select New application.
5. In the Add from the gallery section, type Cisco AnyConnect in the search box.
6. Select Cisco AnyConnect from results panel and then add the app. Wait a few seconds while the app is added to your tenant.

Configure and test Azure AD SSO for Cisco AnyConnect

Configure and test Azure AD SSO with Cisco AnyConnect using a test user called B.Simon. For SSO to work, you need to establish a link relationship between an Azure AD user and the related user in Cisco AnyConnect.

To configure and test Azure AD SSO with Cisco AnyConnect, perform the following steps:

1. Configure Azure AD SSO - to enable your users to use this feature.
   1. Create an Azure AD test user - to test Azure AD single sign-on with B.Simon.
   2. Assign the Azure AD test user - to enable B.Simon to use Azure AD single sign-on.
2. Configure Cisco AnyConnect SSO - to configure the single sign-on settings on application side.
   1. Create Cisco AnyConnect test user - to have a counterpart of B.Simon in Cisco AnyConnect that is linked to the Azure AD representation of user.
3. Test SSO - to verify whether the configuration works.

Configure Azure AD SSO

Follow these steps to enable Azure AD SSO in the Azure portal.

1. In the Azure portal, on the Cisco AnyConnect application integration page, find the Manage section and select single sign-on.

2. On the Select a single sign-on method page, select SAML.

3. On the Set up single sign-on with SAML page, click the edit/pen icon for Basic SAML Configuration to edit the settings.

4. On the Set up single sign-on with SAML page, enter the values for the following fields:

   a. In the Identifier text box, type a URL using the following pattern:< YOUR CISCO ANYCONNECT VPN VALUE >

   b. In the Reply URL text box, type a URL using the following pattern:< YOUR CISCO ANYCONNECT VPN VALUE >

   Note

   These values are not real. Update these values with the actual Identifier and Reply URL. Contact Cisco AnyConnect Client support team to get these values. You can also refer to the patterns shown in the Basic SAML Configuration section in the Azure portal.

5. On the Set up single sign-on with SAML page, in the SAML Signing Certificate section, find Certificate (Base64) and select Download to download the certificate file and save it on your computer.

6. On the Set up Cisco AnyConnect section, copy the appropriate URL(s) based on your requirement.

Note

If you would like to on board multiple TGTs of the server then you need to add multiple instance of the Cisco AnyConnect application from the gallery. Also you can choose to upload your own certificate in Azure AD for all these application instances. That way you can have same certificate for the applications but you can configure different Identifier and Reply URL for every application.

Create an Azure AD test user

In this section, you'll create a test user in the Azure portal called B.Simon.

1. From the left pane in the Azure portal, select Azure Active Directory, select Users, and then select All users.
2. Select New user at the top of the screen.
3. In the User properties, follow these steps:
   1. In the Name field, enter B.Simon.
   2. In the User name field, enter the username@companydomain.extension. For example, B.Simon@contoso.com.
   3. Select the Show password check box, and then write down the value that's displayed in the Password box.
   4. Click Create.

Assign the Azure AD test user

In this section, you'll enable B.Simon to use Azure single sign-on by granting access to Cisco AnyConnect.

1. In the Azure portal, select Enterprise Applications, and then select All applications.
2. In the applications list, select Cisco AnyConnect.
3. In the app's overview page, find the Manage section and select Users and groups.
4. Select Add user, then select Users and groups in the Add Assignment dialog.
5. In the Users and groups dialog, select B.Simon from the Users list, then click the Select button at the bottom of the screen.
6. If you are expecting a role to be assigned to the users, you can select it from the Select a role dropdown. If no role has been set up for this app, you see 'Default Access' role selected.
7. In the Add Assignment dialog, click the Assign button.

Configure Cisco AnyConnect SSO

1. You are going to do this on the CLI first, you might come back through and do an ASDM walk-through at another time.

2. Connect to your VPN Appliance, you are going to be using an ASA running 9.8 code train, and your VPN clients will be 4.6+.

3. First you will create a Trustpoint and import our SAML cert.

4. The following commands will provision your SAML IdP.

5. Now you can apply SAML Authentication to a VPN Tunnel Configuration.

   Note

   There is a feature with the SAML IdP configuration - If you make changes to the IdP config you need to remove the saml identity-provider config from your Tunnel Group and re-apply it for the changes to become effective.

Create Cisco AnyConnect test user

In this section, you create a user called Britta Simon in Cisco AnyConnect. Work with Cisco AnyConnect support team to add the users in the Cisco AnyConnect platform. Users must be created and activated before you use single sign-on.

Test SSO

In this section, you test your Azure AD single sign-on configuration with following options.

• Click on Test this application in Azure portal and you should be automatically signed in to the Cisco AnyConnect for which you set up the SSO
• You can use Microsoft Access Panel. When you click the Cisco AnyConnect tile in the Access Panel, you should be automatically signed in to the Cisco AnyConnect for which you set up the SSO. For more information about the Access Panel, see Introduction to the Access Panel.

Next Steps

Once you configure Cisco AnyConnect you can enforce session control, which protects exfiltration and infiltration of your organization’s sensitive data in real time. Session control extends from Conditional Access. Learn how to enforce session control with Microsoft Cloud App Security.

In computer networking, Cisco ASA 5500 Series Adaptive Security Appliances, or simply Cisco ASA, is Cisco's line of network security devices introduced in May 2005,^[1] that succeeded three existing lines of popular Cisco products:

• Cisco PIX, which provided firewall and network address translation (NAT) functions ended sale on 28 July 2008.^[2]
• Cisco IPS 4200 Series, which worked as intrusion prevention systems (IPS).
• Cisco VPN 3000 Series Concentrators, which provided virtual private networking (VPN).

The Cisco ASA is a unified threat management device, combining several network security functions in one box.^[3]

Reception and criticism[edit]

Cisco ASA has become one of the most widely used firewall/VPN solutions for small to medium businesses.^[4] Early reviews indicated the Cisco GUI tools for managing the device were lacking.^[5]

A security flaw was identified when users customized the Clientless SSLVPN option of their ASA's but was rectified in 2015.^[6]Another flaw in a WebVPN feature was fixed in 2018.^[7]

In 2017 The Shadow Brokers revealed the existence of two privilege escalation exploits against the ASA called EPICBANANA^[8] and EXTRABACON.^[9][10] A code insertion implant called BANANAGLEE, was made persistent by JETPLOW.^[11]

Features[edit]

The 5506W-X has a WiFi point included.

Architecture[edit]

The ASA software is based on Linux. It runs a single Executable and Linkable Format program called lina. This schedules processes internally rather than using the Linux facilities.^[12] In the boot sequence a boot loader called ROMMON (ROM monitor) starts, loads a Linux kernel, which then loads the lina_monitor, which then loads lina. The ROMMON also has a command line that can be used to load or select other software images and configurations. The names of firmware files includes a version indicator, -smp means it is for a symmetrical multiprocessor (and 64 bit architecture), and different parts also indicate if 3DES or AES is supported or not.^[12]

The ASA software has a similar interface to the Cisco IOS software on routers. There is a command line interface (CLI) that can be used to query operate or configure the device. In config mode the configuration statements are entered. The configuration is initially in memory as a running-config but would normally be saved to flash memory.^[12]

Options[edit]

The 5512-X, 5515-X, 5525-X, 5545-X and 5555-X can have an extra interface card added.^[14]

The 5585-X has options for SSP. SSP stands for security services processor.^[15] These range in processing power by a factor of 10, from SSP-10 SSP-20, SSP-40 and SSP-60. The ASA 5585-X has a slot for an I/O module. This slot can be subdivided into two half width modules.^[16]

On the low end models, some features are limited, and uncrippling happens with installation of a Security Plus License. This enables more VLANs, or VPN peers, and also high availability.^[14] Cisco AnyConnect is an extra licensable feature which operates IPSec or SSL tunnels to clients on PCs, iPhones or iPads.^[17]

Models[edit]

The 5505 introduced in 2010 was a desktop unit designed for small enterprises or branch offices. It included features to reduce the need for other equipment, such as an inbuilt switch, and power over Ethernet ports.^[18]The 5585-X is a higher powered unit for datacenters introduced in 2010.^[19] It runs in 32 bit mode on an Intel architecture Atom chip.^[12]

Cisco determined that most of the low end devices had too little capacity to include the features needed, such as anti-virus, or sandboxing, and so introduced a new line called next generation firewall. These run in 64 bit mode.^[12]

Models as of 2018.^[14]
