Sep 23, 2020 Leveraging Cisco AnyConnect to provide remote VPN access to corporate resources is vital to enable a remote workforce. More and more people are using Cisco AnyConnect and Cisco’s Adaptive Security Appliance (ASA) to perform work remotely. It is critical that strong two factor authentication is integrated into Cisco’s VPN solution. Summary A vulnerability in the interprocess communication (IPC) channel of Cisco AnyConnect Secure Mobility Client could allow an authenticated, local attacker to cause a denial of service (DoS) condition on an affected device. To exploit this vulnerability, the attacker would. The Cisco AnyConnect VPN allows you to connect to Mason networks, making access to restricted services possible as if you were on campus. To connect to the VPN from your Windows computer, you need to install the Cisco AnyConnect VPN client. Click Accept to connect to the Stanford Public VPN service. Once the VPN connection is established, a message displays in the lower-right corner of your screen, informing you that you are now connected to the VPN. Disconnect from the Stanford VPN. In the notification area, click the Cisco AnyConnect icon if it is displayed. Cisco AnyConnect - Empower your employees to work from anywhere, on company laptops or personal mobile devices, at any time. AnyConnect simplifies secure endpoint access and provides the security necessary to help keep your organization safe and protected.
For additional information, refer to the AnyConnect configuration guide.
Client Download
Unlike the ASA, the MX does not support web deploy or web launch, a feature that allows end users to access a web page on the AnyConnect server to download the AnyConnect client. With the MX, there are download links to the client software on the AnyConnect settings page on the dashboard, however, the download links are only available to the Meraki dashboard admin and not the end user. We do not recommend sharing the down link with users as the link expires after every five minutes of loading the AnyConnect settings page.
We recommend downloading the AnyConnect client directly from Cisco.com as there may be an updated version in the Cisco repository. Refer to the doc for the AnyConnect clientrelease notes. We also recommend using either Meraki Systems Manager, an equivalent MDM solution, or Active Directory to seamlessly push the AnyConnect software client to the end user's device.
AnyConnect requires a VPN client to be installed on a client device. The AnyConnect client for Windows, MacOS, and Linux are available on the Client Connection section of the AnyConnect configuration page on the dashboard and can be downloaded by a Meraki dashboard administrator. Please note, the download links on the Meraki dashboard expire after five minutes. The AnyConnect client for mobile devices can be downloaded via the respective mobile stores. You can also download other versions (must be version 4.8 or higher) of the AnyConnect client from Cisco.com if you have an existing AnyConnect license. AnyConnect web deploy is not supported on the MX at this time.
- Installing the AnyConnect client
- You only need the VPN box checked. Once the client has been installed on the device, open the AnyConnect application and specify the hostname or IP address of the MX (AnyConnect server) you need to connect to.
AnyConnect Profiles
An AnyConnect profile is a crucial piece for ensuring easy configuration of the AnyConnect client software, once installed. The MX does not support the use of custom hostnames for certificates (e.g. vpn.xyz.com). The MX only supports use of the Meraki DDNS hostname for auto-enrollment and use on the MX. With the Meraki DDNS hostname (e.g. mx450-xyuhsygsvge.dynamic-m.com) not as simply as a custom hostname, the need for AnyConnect profiles cannot be overemphasized. Profiles can be used to create hostname aliases, thereby masking the Meraki DDNS with a friendly name for the end user.
Cisco AnyConnect client features are enabled in AnyConnect profiles. These profiles can contain configuration settings like server list, backup server list, authentication time out, etc., for client VPN functionality, in addition to other optional client modules like Network Access Manager, ISE posture, customer experience feedback, and web security. It is important to note that at this time, the Meraki MX does not support other optional client modules that require AnyConnect head-end support. For more details, see AnyConnect profiles.
When a profile is created, it needs to get pushed to the end user's device. There are three ways to do this.
1. Through the AnyConnect server (MX): If profiles are configured on the dashboard, the MX will push the configured profile to the user's device after successful authentication.
2. Through an MDM solution: Systems Manager, an equivalent MDM solution, or Active Directory can be used push files to specific destinations on the end user's device. Profiles can also be pushed to the following paths:
Windows

Mac OS X
/opt/cisco/anyconnect/profile

Linux
/opt/cisco/anyconnect/profile
3. Manually: Profiles can also be preloaded manually to the same paths as listed above.

How to Create a Profile
Profiles can be created using the AnyConnect profile editor. The profile editor can be downloaded from the AnyConnect Settings page on dashboard or on cisco.com. Refer to this link for more details on AnyConnect profiles.
Using the profile editor: The profile editor can be downloaded from the AnyConnect Settings page on dashboard or on Cisco.com. The profile editor only runs on Windows operating systems. The screenshot below shows a configured server ton the Server List Entry option.
When configuration is complete, save the profile. It is recommended to use a unique file name to avoid profile overrides by other AnyConnect servers, then you can upload the file to the profile update section on the AnyConnect settings page.
Please note that only VPN profiles are supported on the MX at this time. This means you cannot push NVM, NAM, or Umbrella profiles via the MX.

- Select enable profiles, upload your xml file, and save your configuration
- After a user successfully authenticates, the configured profile gets pushed to the user's device automatically
- The result of the .xml can be seen below, after successful authentication to the AnyConnect server; this gives users the ease of selecting VPN servers on the AnyConnect client
The Meraki DDNS hostname is not easy to remember, therefore end users are not expected to use it directly. Profiles should be used to make connecting to the AnyConnect server easy for end users.
