AnyConnect offers a number of features that go beyond this, granting admins with extended visibility and control of workers. It also provides IP-based policy capabilities, meaning connections can be blocked and access restricted.
The functionality is limited however, as it is unable to manipulate traffic at the application level and is not network-aware, which means policy cannot be based on the conditions of the request.
More intelligent policy engines can factor in the strength and security of a network, the configuration of the device, the application being used and even the category and risk profile of a website that a user is visiting. Cisco AnyConnect does not gather any of this data and does not allow for granular or context-sensitive policy controls. When employees are working inside an office or a location in close proximity to the IT team, using corporate-managed networks and on company-owned devices, troubleshooting is relatively straightforward.
Network problems can be diagnosed, devices can be updated and issues identified. Challenges emerge for remote workers, however. Working on rapidly-changing networks, from home WiFi to cellular connections, means that helpdesk are often entirely unable to help remote workers figure out solutions to the problems they might encounter. While not a traditional component of a VPN, some are able to provide rich data into the configuration of the device, the performance of the network and hundreds of other potential causes of issues as they emerge — such as employees struggling with ccaptive portals on public WiFi or misconfigured SIM cards.
Equipped with these insights, IT support is able to understand employee problems much more swiftly and effectively, enabling remote workforces to be more productive and happier overall. Unfortunately Cisco AnyConnect does not feature any diagnostics, visibility or analytics functionality, leaving remote workers at the mercy of their own ability to troubleshoot IT issues.
Cisco AnyConnect is in widespread use and is frequently bundled alongside other Cisco deployments. All kinds of companies get great value from their AnyConnect investments, and it will continue to be a reliable, straightforward choice for many. To create the PEM file certificate store, create the paths and folders listed below. Place the appropriate certificates in these folders:.
Machine certificates are the same as PEM file certificates, except for the root directory. Otherwise, the paths, folders, and types of certificates listed apply. AnyConnect can limit its search of certificates to those certificates that match a specific set of keys. The criteria are:.
Selecting the Key Usage keys limits the certificates that AnyConnect can use to those certificates that have at least one of the selected keys. If one or more criteria are specified, a certificate must match at least one to be considered a matching certificate. Selecting the Extended Key Usage keys limits the certificates that AnyConnect can use to the certificates that have these keys.
The following table lists the well-known set of constraints with their corresponding object identifiers OIDs. All other OIDs such as 1. The Distinguished Name table contains certificate identifiers that limit the certificates that the client can use to the certificates that match the specified criteria and criteria match conditions.
Click the Add button to add criteria to the list and to set a value or wildcard to match the contents of the added criteria. Distinguished Name can contain zero or more matching criteria. A certificate must match all specified criteria to be considered a matching certificate. Distinguished Name matching specifies that a certificate must or must not have the specified string, and whether wild carding for the string is allowed.
RSA SecurID software authenticators reduce the number of items a user has to manage for safe and secure access to corporate assets. Typically, users make an AnyConnect connection by clicking the AnyConnect icon in the tools tray, selecting the connection profile with which they wish to connect, and then entering the appropriate credentials in the authentication dialog box.
The login challenge dialog box matches the type of authentication configured for the tunnel group to which the user belongs. The input fields of the login dialog box clearly indicate what kind of input is required for authentication. After the user enters the passcode into the secured application, the RSA Authentication Manager validates the passcode and allows the user to gain access.
Users who use RSA SecurID hardware or software tokens see input fields indicating whether the user should enter a passcode or a PIN, a PIN, or a passcode and the status line at the bottom of the dialog box provides further information about the requirements. In either case, the secure gateway sends the client a login page.
The main login page contains a drop-down list in which the user selects a tunnel group; the tunnel-group login page does not, since the tunnel-group is specified in the URL. In the case of a main login page with a drop-down list of connection profiles or tunnel groups , the authentication type of the default tunnel group determines the initial setting for the password input field label.
For a tunnel-group login page, the field label matches the tunnel-group requirements. With each successful authentication, the client saves the tunnel group, the username, and authentication type, and the saved tunnel group becomes the new default tunnel group.
AnyConnect accepts passcodes for any SDI authentication. The client sends the passcode to the secure gateway as is. Automatic—The client first attempts one method, and if it fails, the other method is tried. The default is to treat the user input as a token passcode HardwareToken , and if that fails, treat it as a software token pin SoftwareToken.
When authentication is successful, the successful method is set as the new SDI Token Type and cached in the user preferences file. Generally, the token used for the current authentication attempt is the same token used in the last successful authentication attempt. However, when the username or group selection is changed, it reverts to attempting the default method first, as shown in the input field label.
HardwareToken as the default avoids triggering next token mode. AnyConnect does not support token selection from multiple tokens imported into the RSA Software Token client software. All SDI authentication exchanges fall into one of the following categories:. A normal login challenge is always the first challenge. The SDI authentication user must provide a user name and token passcode or PIN, in the case of a software token in the username and passcode or PIN fields, respectively.
If the authentication server accepts the authentication request, the secure gateway sends a success page back to the client, and the authentication exchange is complete. If the passcode is not accepted, the authentication fails, and the secure gateway sends a new login challenge page, along with an error message. If the passcode failure threshold on the SDI server has been reached, then the SDI server places the token into next token code mode.
Clear PIN mode and New User mode are identical from the point of view of the remote user and are both treated the same by the secure gateway. The only difference is in the user response to the initial challenge. In these modes, for hardware tokens, the user enters just a token code from the RSA device. If there is no current PIN, the SDI server requires that one of the following conditions be met, depending on how the system is configured:.
The system must assign a new PIN to the user Default. The user can choose whether to create a PIN or have the system assign it. If the SDI server is configured to allow the remote user to choose whether to create a PIN or have the system assign a PIN, the login screen presents a drop-down list showing the options. The status line provides a prompt message.
For a system-assigned PIN, if the SDI server accepts the passcode that the user enters on the login page, then the secure gateway sends the client the system-assigned PIN. The PIN must be a number from 4 to 8 digits long. Because the PIN is a type of password, anything the user enters into these input fields is displayed as asterisks. The network administrator can configure the secure gateway to allow SDI authentication in either of the following modes:.
Otherwise, the prompts displayed to the remote client user might not be appropriate for the action required during authentication. AnyConnect might fail to respond and authentication might fail. Since both ultimately communicate with the SDI server, the information needed from the client and the order in which that information is requested is the same.
Within these challenge messages are reply messages containing text from the SDI server. Otherwise, the prompts displayed to the remote client user may not be appropriate for the action required during authentication.
Users authenticating to the SDI server must connect over this connection profile. Check Enable the display of SecurID messages on the login screen.
Double-click a message text field to edit the message. Because the security appliance searches for strings in the order in which they appear in the table, you must ensure that the string you use for the message text is not a subset of another string. The client confirms the PIN without prompting the user. Indicates the user-supplied PIN was accepted.
Follows a PIN operation and indicates the user must wait for the next tokencode and to enter both the new PIN and next tokencode to authenticate. Click OK , then Apply , then Save. Skip to content Skip to search Skip to footer. Book Contents Book Contents.
Find Matches in This Book. PDF - Complete Book 6. Updated: July 14, Terminating an AnyConnect Connection Terminating an AnyConnect connection requires the user to re-authenticate their endpoint to the secure gateway and create a new VPN connection. The following connection parameters terminate the VPN session based on timeouts: Maximum Connect Time—Sets the maximum user connection time in minutes.
Step 2 Click Add. Step 4 Enter the server to fall back to as the backup server in the Backup Server List. Note Conversely, the Backup Server tab on the Server menu is a global entry for all connection entries. Step 8 Click OK.
Step 2 Select a group policy and click Edit or Add a new group policy. Note The user must reboot the remote computer before SBL takes effect. Step 5 Browse back to the security appliance to install AnyConnect again. Step 6 Reboot once. Host data not available. Step 9 Go back to the. Step 2 Select Auto Reconnect. The following workarounds will help you prevent this problem: Enable TND in the client profiles loaded on all the ASAs on your corporate network.
Step 3 Choose a Trusted Network Policy. Step 4 Choose an Untrusted Network Policy. The options are: Connect—The client starts a VPN connection upon the detection of an untrusted network.
Step 7 Specify a host URL that you want to add as trusted. Guidelines for Always-On VPN To enhance protection against threats, we recommend the following additional protective measures if you configure Always-On VPN: We strongly recommend purchasing a digital certificate from a certificate authority CA and enrolling it on the secure gateways.
Step 2 Choose a server that is a primary device of a load-balancing cluster and click Edit. Guidelines for Setting the Connect Failure Policy Consider the following when using an open policy which permits full network access: Security and protection are not available until the VPN session is established; therefore, the endpoint device may get infected with web-based malware or sensitive data may leak. Consider the following when using a closed policy which disables all network connectivity until the VPN session is established: A closed policy can halt productivity if users require Internet access outside the VPN.
Step 2 Set the Connect Failure Policy parameter to one of the following settings: Closed— Default Restricts network access when the secure gateway is unreachable.
AnyConnect reacts to the detection of a captive portal depending on the current configuration: If Always-On is disabled, or if Always-On is enabled and the Connect Failure Policy is open, the following message is displayed on each connection attempt: The service provider in your current location is restricting access to the Internet.
You need to log on with the service provider before you can establish a VPN session. You can try this by visiting any website with your browser. The service provider in your current location is restricting access to the Internet. The AnyConnect protection settings must be lowered for you to log on with the service provider.
Your current enterprise security policy does not allow this. Configure Captive Portal Remediation You configure captive portal remediation only when the Always-On feature is enabled and the Connect Failure Policy is set to closed. Step 3 Specify the Remediation Timeout. Troubleshoot Captive Portal Detection and Remediation AnyConnect can falsely assume that it is in a captive portal in the following situations. If users cannot access a captive portal remediation page, ask them to try the following: Terminate any applications that use HTTP, such as instant messaging programs, e-mail clients, IP phone clients, and all but one browser to perform the remediation.
Restart the computer. Disabled—PPP exclusion is not applied. Step 4 Exit and restart AnyConnect. Public Proxy Connections: Public proxies are usually used to anonymize web traffic. Private Proxy Connections: Private proxy servers are used on a corporate network to prevent corporate users from accessing certain Web sites based on corporate usage policies, for example, pornography, gambling, or gaming sites. Note AnyConnect SBL connections through a proxy server are dependent on the Windows operating system version and system machine configuration or other third-party proxy software capabilities; therefore, refer to system wide proxy settings as provided by Microsoft or whatever third-party proxy application you use.
A VPN client profile is required to allow access to a local proxy. Note In a macOS environment, the proxy information that is pushed down from the ASA upon a VPN connection is not viewed in the browser until you open up a terminal and issue a scutil --proxy.
The conditions under which this lock down occurs are the following: The ASA configuration specifies Connections tab lockdown. Step 4 Click Proxy Lockdown to display more proxy settings. Step 5 Uncheck Inherit and select Yes to enable proxy lockdown and hide the Internet Explorer Connections tab for the duration of the AnyConnect session or; select No to disable proxy lockdown and expose the Internet Explorer Connections tab for the duration of the AnyConnect session.
Step 7 Click Apply to save the Group Policy changes. Step 4 Next to Client Bypass Protocol , uncheck Inherit if this is a group policy other than the default group policy. Step 6 Click OK. Step 7 Click Apply. Note This process assumes that the domains pushed from the ASA do not overlap with the ones already configured on the client host.
The following rules are applied for the purposes of IPsec and SSL name verification: If a Subject Alternative Name extension is present with relevant attributes, name verification is performed solely against the Subject Alternative Name. Invalid Server Certificate Handling In response to the increase of targeted attacks against mobile users on untrusted networks, we have improved the security protections in the client to help prevent serious security breaches.
User Interaction When the user tries to connect to a secure gateway, and there is a certificate error due to expired, invalid date, wrong key usage, or CN mismatch , the user sees a red-colored dialog with Change Settings and Keep Me Safe buttons.
Note The dialogs for Linux may look different from the ones shown in this document. If the user un-checks Block connections to untrusted servers , and the only issue with the certificate is that the CA is untrusted, then the next time the user attempts to connect to this secure gateway, the user will not see the Certificate Blocked Error Dialog dialog; they only see the following dialog: If the user checks Always trust this VPN server and import the certificate , then future connections to this secure gateway will not prompt the user to continue.
Improved Security Behavior When the client accepts an invalid server certificate, that certificate is saved in the client's certificate store. Configure Certificate-Only Authentication You can specify whether you want users to authenticate using AAA with a username and password or using a digital certificate or both.
Note The certificate used to authenticate the client to the secure gateway must be valid and trusted signed by a CA. Step 2 If it is not already, click the Basic node of the navigation tree on the left pane of the window. Step 3 Click OK and apply your changes. Other SCEP Proxy operational considerations: If configured to do so, the client automatically renews the certificate before it expires, without user intervention.
If the client is configured for manual enrollment and the client knows it needs to initiate SCEP enrollment see Step 2 , a Get Certificate button displays on the credentials dialog box. Other Legacy SCEP operational considerations: If the client is configured for manual enrollment and the Certificate Expiration Threshold value is met, a Get Certificate button displays on a presented tunnel group selection dialog box.
Certificate-Only Authentication and Certificate Mapping on the ASA: To support certificate-only authentication in an environment where multiple groups are used, you may provision more than one group-url. Windows Certificate Warning: When Windows clients first attempt to retrieve a certificate from a certificate authority they may see a warning.
Step 2 Select Certificate Enrollment. Step 3 Configure the Certificate Contents to be requested in the enrollment certificate. Step 5 Configure which Certificate Contents to request in the enrollment certificate. Step 6 Optional Check Display Get Certificate Button to permit users to manually request provisioning or renewal of authentication certificates. Step 3 Edit EnforcePassword, and set it to '0'. Step 4 Exit regedit, and reboot the certificate authority server. Procedure Step 1 Launch the Server Manager.
Step 8 Adjust the Validity Period for your site. Step 9 On the Cryptography tab, set the minimum key size for your deployment.
Step 12 Click Apply , then OK to save new template. Step 14 Edit the registry. Configure a Certificate Expiration Notice Configure AnyConnect to warn users that their authentication certificate is about to expire. Step 3 Specify a Certificate Expiration Threshold. Step 4 Click OK. Configure Certificate Selection The following steps show all the places in the AnyConnect profiles where you configure how certificates are searched for and how they are selected on the client system.
Step 2 Windows Only: Prompt Windows Users to Select Authentication Certificate Configure AnyConnect to present a list of valid certificates to users and let them choose the certificate to authenticate the session. Step 5 Configure Certificate Matching Configure keys that AnyConnect tries to match, when searching for a certificate in the store. Note Access-control for the machine store can vary depending on the Windows version and security settings. Because of this, the user may be unable to use certificates in the machine store even though they have administrative privileges.
In this case, select Certificate Store Override to allow machine store access. All for Windows checked AnyConnect searches all certificate stores. Machine not a multi-cert option checked AnyConnect searches the machine certificate store. Machine not a multi-cert option cleared AnyConnect searches the machine certificate store.
Assuming this is correct, how does the tunnel interface packets get sent over the TLS connection? Now that's still technically a client, just one that doesn't have to be explicitly installed. So what makes things confusing is that the same Cisco AnyConnect product can fit any of these descriptions: its protocol is based on DTLS; it provides a Java-applet client; and it provides a webapp gateway in addition to traditional VPN.
But that doesn't mean the same mode fits all three descriptions at once: e. There is also client-less WebVPN where you browse to an internal site on the ASA, authenticate just like you're using AnyConnect, but then you access internal servers via that web portal. The advantage is that your entire connction isn't tunneled - it's only whatever you access through the web portal. It gets pricey. Sign up to join this community.
