If you need support for that feature, use SSL. Configuring Antivirus Applications for HostScan Antivirus applications can misinterpret the piece of some of the applications included in the posture module and the HostScan package as malicious. Your USC NetID username and password are the username and password you use to connect to services such as and Workday. Note Machine authentication allows a client desktop to be met to the network before the user logs in. The information in this document is intended for end users of Cisco products. VPN, also called IP tunneling, is a secure method of accessing USC computing resources. Simple to deploy and use, our IPSecurity IPsec -based VPN met is compatible with all Cisco VPN products. Microsoft's fix for this error is planned for June 2017. Likewise, our crypto toolkit has discontinued support for RC4 ciphers; therefore, our support for them will be dropped with releases 3. Click Yes to continue. If you experience a responsible with an out-of-date software version, you may be asked to validate whether the current maintenance release resolves your issue. IKEv2 applies the proxy configuration sent from the gateway, and subsequent HTTP traffic is subject to that proxy configuration.
If you deploy always-on VPN, you might want to enable split tunneling and configure firewall rules to restrict network access to local printing and tethered mobile devices. The Cisco VPN Client can be preconfigured for mass deployments Requires little user intervention for initial logins Supports Cisco Easy VPN capabilities, decreasing network security policy configuration at the remote location Complements the Cisco AnyConnect Secure Mobility Client. You can then reinstall the module after the upgrade.
Helpdesk DICT - Users who web deploy or who already have AnyConnect installed are not impacted. If the scanning proxy finds an IPv4 address, it uses that for the connection.
Step 2 Log in to Cisco. Step 3 Click Download Software. Step 4 Expand the Latest Releases folder and click the latest release, if it is not already selected. Step 6 Read and accept the Cisco license agreement when prompted. Step 7 Select a local directory in which to save the downloads and click Save. Step 8 See the. Note These features require ISE 2. When the grace period expires, AnyConnect performs the posture check again, this time with no remediation and determines the endpoint state based on the results of the check. Important Notes An enhanced version of SAML integration with an embedded browser has replaced the native external browser integration from previous releases. The new version with the embedded browser requires you to upgrade to AnyConnect 4. Refer to in the AnyConnect Secure Mobility Client Administrator Guide, Release 4. Older releases of AnyConnect must be web-deployed from an ASA, pre-deployed with an SMS, or manually deployed. ISE Licensing Requirements To deploy AnyConnect from an ISE headend and use the ISE Posture module, a Cisco ISE Apex License is required on the ISE Administration node. For detailed ISE license information, see the Cisco ISE Licenses chapter of the. These services let you enforce acceptable use policies and protect endpoints from websites found to be unsafe, by granting or denying all HTTP and HTTPS requests. If you deploy always-on VPN, you might want to enable split tunneling and configure firewall rules to restrict network access to local printing and tethered mobile devices. ASA Memory Requirements Caution The minimum flash memory recommended for all ASA 5500 models using AnyConnect 4. This will allow hosting of multiple endpoint operating systems, and logging and debugging to be enabled on the ASA. Due to flash size limitations on the ASA 5505 maximum of 128 MB , not all permutations of the AnyConnect package will be able to be loaded onto this model. To successfully load AnyConnect, you will need to reduce the size of your packages i. Check for the available space before proceeding with the AnyConnect install or upgrade. The File Management window displays flash space. If your ASA has only the default internal flash memory size or the default DRAM size for cache memory , you could have problems storing and loading multiple AnyConnect client packages on the ASA. Even if you have enough space on the flash to hold the package files, the ASA could run out of cache memory when it unzips and loads the client images. For additional information about the ASA memory requirements and upgrading ASA memory, see the. VPN Posture and HostScan Interoperability The VPN Posture HostScan Module provides the Cisco AnyConnect Secure Mobility Client the ability to identify the operating system, antimalware, and firewall software installed on the host to the ASA. The VPN Posture HostScan Module requires HostScan to gather this information. HostScan, available as its own software package, is periodically updated with new operating system, antimalware, and firewall software information. The usual recommendation is to run the most recent version of HostScan which is the same as the version of AnyConnect. The ISE Posture compliance module contains the list of supported antimalware and firewall for ISE posture. While the HostScan list organized by vendor, the ISE posture list organizes by product type. When the version number on the headend ISE or ASA is greater than the version on the endpoint, the OPSWAT gets updated. These upgrades are mandatory and happen automatically without end user intervention. The individual files within the library a zip file are digitally signed by OPSWAT, Inc. Refer to the for details. IOS Support of AnyConnect Cisco supports AnyConnect VPN access to IOS Release 15. Refer to for additional IOS feature support information. AnyConnect Supported Operating Systems Cisco AnyConnect Secure Mobility Client supports the following operating systems for its contained modules: Supported Operating Systems VPN Client Network Access Manager Cloud Web Security VPN Posture HostScan ISE Posture DART Customer Experience Feedback Network Visibility Module AMP Enabler Umbrella Roaming Security Windows 7, 8, 8. Manually uninstall AnyConnect, upgrade Windows, then reinstall AnyConnect manually or via WebLaunch. There are no APIs provided in the operating system to implement this functionality. Cisco has an open request with Microsoft on this topic. Those who want this functionality should contact Microsoft to express their interest. To work around this problem, uninstall Wireshark or disable the WinPcap service, reboot your Windows 8 computer, and attempt the AnyConnect connection again. To work around this problem, make sure you have the latest wireless network cards or drivers that support Windows 8 installed on your Windows 8 computer. If you find the Scanlist in Windows appears shorter than expected, increase the association timer so that the driver can complete a network scan and populate the scanlist. Drivers that are not supported may have intermittent connection problems. This change permits Local Security Authority LSA to provide clients like Cisco Network Access Manager with the Machine password. Machine authentication using Machine certificate does not require this change and will work the same as it worked with pre-Windows 8 operating systems. Note Machine authentication allows a client desktop to be authenticated to the network before the user logs in. During this time the administrator can perform scheduled administrative tasks for this client machine. Machine authentication is also required for the EAP Chaining feature where a RADIUS server can authenticate both the User and Machine for a particular client. This will result in identifying company assets and applying appropriate access policies. In other versions of Windows, the user is asked where to save the file. Superuser privileges are required for installation. The only version that works for web installation is Sun Java. You must install Sun Java and configure your browser to use that instead of the default package. AnyConnect Support for Mac Mac OS X 10. AnyConnect is a signed application, but it is not signed using an Apple certificate. This means that you must either select the Anywhere setting or use Control-click to bypass the selected setting to install and run AnyConnect from a pre-deploy installation. Users who web deploy or who already have AnyConnect installed are not impacted. For further information, refer to Apple documentation. Note For the latest end-user license agreement, see. For our open source licensing acknowledgments, see. To deploy AnyConnect from an ISE headend and use the ISE Posture module, a Cisco ISE Apex License is required on the ISE Administration node. For detailed ISE license information, see the Cisco ISE Licenses chapter of the. To deploy AnyConnect from an ASA headend and use the VPN and VPN Posture HostScan modules, an AnyConnect 4. X Plus or Apex license is required, trial licenses are available, see the. For an overview of the AnyConnect 4. X Plus and Apex licenses and a description of which license the features use, see. AnyConnect Installation Overview Deploying AnyConnect refers to installing, configuring, and upgrading the AnyConnect client and its related files. When the user connects to an ASA or to ISE, AnyConnect is deployed to the client. The client is either installed manually, or automatically web-launch. With Cloud Update, the software upgrades are obtained automatically from the Umbrella cloud infrastructure, and the update track is dependent upon that and not any action of the administrator. By default, automatic updates from Cloud Update are disabled. When you deploy AnyConnect, you can include the optional modules that enable extra features, and client profiles that configure the VPN and other features. When pre-deploying, you must pay special attention to the module installation sequence and other details. Note This issue applies to Internet Explorer versions 10 and 11, on Windows versions 7 and 8. See for more information. Note Cisco only provides fixes and enhancements based on the most recent 4. TAC support is available to any customer with an active AnyConnect 4. If you experience a problem with an out-of-date software version, you may be asked to validate whether the current maintenance release resolves your issue. Software Center access is limited to AnyConnect 4. We recommend that you download all images for your deployment, as we cannot guarantee that the version you are looking to deploy will still be available for download at a future date. Guidelines and Limitations Changes with Certificate Store Database NSS Library Updates on Firefox58 Only Impacting RedHat and Ubuntu users prior to 18. Once NSS is updated to version 3. Conflict with Network Access Manager and Group Policy Windows 10 version 1703 changed their WLAN behavior, which caused disruptions when the Network Access Manager scans for wireless network SSIDs. Because of a bug with the Windows code that Microsoft is investigating, the Network Access Manager's attempt to access hidden networks is impacted. To provide the best user experience, we have disabled Microsoft's new functionality by setting two registry keys during Network Access Manager installation and removing them during an uninstall. The requirement to manually enable the software extension is a new operating system requirement in macOS 10. Additionally, if AnyConnect is upgraded to 4. Users running macOS 10. You may need to manually reboot after enabling the extension prior to AnyConnect 4. As described in , macOS system administrators potentially have additional capabilities to disable User Approved Kernel Extension Loading, which would be effective with any currently supported version of AnyConnect. Only the NAM, DART, ISE Posture, and Posture modules that are deployed as MSI files are affected. Because of the use of SHA-2 timestamping certificate service, the most up-to-date trusted root certificates are required to properly validate the timestamp certificate chain. You will not have this issue with predeploy or an out-of-the-box Windows system configured to automatically update root certificates. However, if the automatic root certificate update setting has been disabled not the default , refer to or manually install the timestamping root certificates that we use. You can also use the signtool to verify if the issue is outside of AnyConnect by running the signtool. The prompt only occurs when access to a client certificate private key is necessary, after a client certificate request from the secure gateway. Even if the tunnel group is not configured with certificate authentication, certificate mapping may be configured on the ASA, causing the keychain prompts when the access control setting for the client certificate private key is configured as Confirm Before Allowing Access. CSCuv78008 tracks an enhancement request to extend support for profile-based certificate store filtering to macOS. This enhancement allows you to restrict AnyConnect access strictly to user certificates from the login keychain without configuring certificate matching criteria in the profile. Umbrella Roaming Security Plugin Changes Microsoft intended to block updates to earlier versions of Windows when the Network Access Manager is installed, but Windows 10 and Creators Edition RS2 were inadvertently blocked as well. Because of the error Microsoft Sysdev 11911272 , you must first uninstall the Network Access Manager module before you can upgrade to the Creators Editor RS2. You can then reinstall the module after the upgrade. Microsoft's fix for this error is planned for June 2017. Windows Defender instructs you to enable the adapter under the Device Performance and Health section. In actuality, the adapter should be disabled when not in use, and no manual action should be taken. This false positive error has been reported to Microsoft under Sysdev 11295710. AnyConnect Compatibility with Microsoft Windows 10 AnyConnect 4. The Network Access Manager Module must be uninstalled prior to upgrading to Windows 10. After the system upgrade is complete, you can re-install Network Access Manager on the system. You may also choose to fully uninstall AnyConnect and re-install one of the supported versions after upgrading to Windows 10. Win32 Limitation With Connected Standby Formerly, if a split-include network was a Supernet of a Local Subnet, the local subnet traffic was not tunneled unless a split-include network that exactly matches the Local Subnet was configured. With the resolution of CSCum90946, when a split-include network is a Supernet of a Local Subnet, the Local Subnet traffic is tunneled, unless a split-include deny 0. You also have the option to make it user controllable. After February 14, 2017, Windows endpoints may no longer consider a secure gateway with a SHA-1 certificate or intermediate certificate as trusted. We highly recommend that your secure gateway does not have a SHA-1 identity certificate and that any intermediate certificates are not SHA-1. Microsoft has made modifications to their original plan of record and timing. They have published details for how to. Cisco is not able to make any guarantees of correct AnyConnect operation for customers with SHA-1 secure gateway or intermediate certificates or running old versions of AnyConnect. Cisco highly recommends that customers stay up to date with the current maintenance release of AnyConnect in order to ensure that they have all available fixes in place. The most up-to-date version of AnyConnect 4. Note Cisco has validated that AnyConnect 4. Long term, Microsoft intends to distrust SHA-1 throughout Windws in all contexts, but their current advisory does not provide any specifics or timing on this. Depending on the exact date of that deprecation, many earlier versions of AnyConnect may no longer operate at any time. Refer to for further information. Authentication Failure When Using a SHA512 Certificate for Authentication For Windows 7, 8, and 8. The ASA logs correctly show that no certificate was sent by AnyConnect. These versions of Windows require that you enable support for SHA512 certificates in TLS 1. Refer to for information on enabling support for these SHA512 certificates. No Longer Supporting RC4 TLS Cipher Suite Because the OpenSSL standards development team marked some cipher suites as compromised, we no long support them beyond AnyConnect 3. The unsupported cipher suites include the following: DES-CBC-SHA, RC4-SHA, and RC4-MD5. Likewise, our crypto toolkit has discontinued support for RC4 ciphers; therefore, our support for them will be dropped with releases 3. Using Log Trace in ISE Posture If you are using Mac OS X 10. Firefox Certificate Store on Mac OS X is Not Supported The Firefox certificate store on Mac OS X is stored with permissions that allow any user to alter the contents of the store, which allows unauthorized users or processes to add an illegitimate CA into the trusted root store. Anyconnect no longer utilizes the Firefox store for either server validation or client certificates. If necessary, instruct your users how to export your AnyConnect certificates from their Firefox certificate stores, and how to import them into the Mac OS X keychain. The following steps are an example of what you may want to tell your AnyConnect users. Your AnyConnect Certificate s will most likely be located under the Authorities category. Verify with your Certificate Administrator, as they may be located under a different category Your Certificates or Servers. Navigate to File, Import Items…, and select the Certificate that you exported from Firefox. In the Destination Keychain:, select the desired Keychain. The login Keychain that is used for this example may not be the one used at your company. Ask your Certificate Administrator to which Keychain your certificate s should be imported. The login Keychain that is used for this example may not be the one used at your company. Ask your Certificate Administrator to which keychain your certificate s should be imported. On many newer Linux distributions, the AnyConnect UI may fail to start with the error: error while loading shared libraries: libpangox-1. This impacts other applications, not just AnyConnect. Pango has released the source code of a compatible library that has been built by others and is available online. To resolve this problem, find and install either the package pangox-compat-0. SSLv3 Prevents HostScan From Working There is an issue with Weblaunch with Safari. The default security settings in the version of Safari that comes with OS X 10. To configure Safari to allow Weblaunch, edit the URL of the ASA to Unsafe Mode, as described below. Active X Upgrade Can Disable Weblaunch Automatic upgrades of AnyConnect software via WebLaunch will work with limited user accounts as long as there are no changes required for the ActiveX control. Occasionally, the control will change due to either a security fix or the addition of new functionality. Should the control require an upgrade when invoked from a limited user account, the administrator must deploy the control using the AnyConnect pre-installer, SMS, GPO or other administrative deployment methodology. If you encounter any issues with AnyConnect in your virtual environment, report them. We will make our best effort to resolve them. UTF-8 Character Support for AnyConnect Passwords When Auto Update is disabled for a client running AnyConnect, the ASA must have the same version of AnyConnect or earlier installed, or the client will fail to connect to the VPN. To avoid this problem, configure the same version or earlier AnyConnect package on the ASA, or upgrade the client to the new version by enabling Auto Update. Interoperability between Network Access Manager and other Connection Managers When the Network Access Manager operates, it takes exclusive control over the network adapters and blocks attempts by other software connection managers including the Windows native connection manager to establish connections. Therefore, if you want AnyConnect users to use other connection managers on their endpoint computers such as iPassConnect Mobility Manager , they must disable Network Access Manager either through the Disable Client option in the Network Access Manager GUI, or by stopping the Network Access Manager service. If the CSP does not support SHA 2 algorithms, and the ASA is configured for the pseudo-random function PRF SHA256, SHA384, or SHA512, and the connection profile tunnel-group is configured for certificate or certificate and AAA authentication, certificate authentication fails. The user receives the message Certificate Validation Failure. This failure occurs for Windows only, for certificates that belong to CSPs that do not support SHA 2-type algorithms. Other supported OSs do not experience this problem. To avoid this problem you can configure the PRF in the IKEv2 policy on the ASA to md5 or sha SHA 1. Alternatively, you can modify the certificate CSP value to native CSPs that work such as Microsoft Enhanced RSA and AES Cryptographic Provider. Do not apply this workaround to SmartCards certificates. You cannot change the CSP names. Instead, contact the SmartCard provider for an updated CSP that supports SHA 2 algorithms. Caution Performing the following workaround actions could corrupt the user certificate if you perform them incorrectly. Use extra caution when specifying changes to the certificate. You can use the Microsoft Certutil. Certutil is a command-line utility for managing a Windows CA, and is available in the Microsoft Windows Server 2003 Administration Tools Pack. You can download the Tools Pack at this URL: Follow this procedure to run Certutil. In the example, the CN is Carol Smith. You need this information for the next step. The example below uses the subject value to select the certificate to modify. You can also use other attributes. Configuring Antivirus Applications for HostScan Antivirus applications can misinterpret the behavior of some of the applications included in the posture module and the HostScan package as malicious. If you need support for that feature, use SSL. Private-side proxies are supported by both IKEv2 and SSL as dictated by the configuration sent from the secure gateway. IKEv2 applies the proxy configuration sent from the gateway, and subsequent HTTP traffic is subject to that proxy configuration. MTU Adjustment on Group Policy May Be Required for IKEv2 AnyConnect sometimes receives and drops packet fragments with some routers, resulting in a failure of some web traffic to pass. To avoid this, lower the value of the MTU. MTU Automatically Adjusted When Using DTLS If Dead Peer Detection DPD is enabled for DTLS, the client automatically determines the path MTU. If you previously reduced the MTU using the ASA, you should restore the setting to the default 1406. During tunnel establishment, the client auto-tunes the MTU using special DPD packets. If you still have a problem, use the MTU configuration on the ASA to restrict the MTU as before. Network Access Manager and Group Policy Windows Active Directory Wireless Group Policies manage the wireless settings and any wireless networks that are deployed to PCs in a specific Active Directory Domain. When installing the Network Access Manager, administrators must be aware that certain wireless Group Policy Objects GPOs can affect the behavior of the Network Access Manager. Administrators should test the GPO policy settings with the Network Access Manager before doing full GPO deployment. FreeRADIUS Configuration to Work With Network Access Manager A mobile endpoint running Windows 7 or later must do a full EAP authentication instead of leveraging the quicker PMKID reassociation when the client roams between access points on the same network. Consequently, in some cases, AnyConnect prompts the user to enter credentials for every full authentication if the active profile requires it. User Guideline for Cisco Cloud Web Security Behavior with IPv6 Web Traffic Unless an exception for an IPv6 address, domain name, address range, or wild card is specified, IPv6 web traffic is sent to the scanning proxy where it performs a DNS lookup to see if there is an IPv4 address for the URL the user is trying to reach. If the scanning proxy finds an IPv4 address, it uses that for the connection. If it does not find an IPv4 address, the connection is dropped. Doing this makes all IPv6 traffic bypass all scanning proxies. This means that IPv6 traffic is not protected by Cisco Cloud Web Security. However, the other devices cannot access these hosts. To ensure the AnyConnect host prevents the hostname leak between subnets, including the name of the AnyConnect endpoint host, configure that endpoint to never become the master or backup browser. The Edit String window opens. Revocation Message An AnyConnect certificate revocation warning popup window opens after authentication if AnyConnect attempts to verify a server certificate that specifies the distribution point of an LDAP certificate revocation list CRL if the distribution point is only internally accessible. Caution When the AnyConnect client for Mac OS X attempts to create an SSL connection to a gateway running IOS, or when the AnyConnect client attempts to create an IPsec connection to an ASA from behind certain types of routers such as the Cisco Virtual Office CVO router , some web traffic may pass through the connection while other traffic drops. AnyConnect may calculate the MTU incorrectly. To work around this problem, manually set the MTU for the AnyConnect adaptor to a lower value using the following command from the Mac OS X command line: sudo ifconfig utun0 mtu 1200 For Mac OS X v10. The SSLv3 key derivation algorithm uses MD5 and SHA-1 in a way that can weaken the key derivation. TLSv1, the successor to SSLv3, resolves this and other security issues present in SSLv3. As a workaround, you can disconnect any physical network adapters not used for VPN connection or disable proxy auto-discovery in IE, if proxy auto-discovery is not supported by the current network environment. Users with Limited Privileges Cannot Upgrade ActiveX If users WebLaunch from the ASA headend to start AnyConnect on a Mac, and the Java installer fails, a dialog box presents a Manual Install link. A dialog box presents the option to save a. No Pro-Active Key Caching PKC or CCKM Support The AnyConnect Secure Mobility Client includes an Application Programming Interface API for those who want to write their own client programs. The API package contains documentation, source files, and library files to support a C++ interface for the Cisco AnyConnect VPN Client. You can use the libraries and example programs for building on Windows, Linux and MAC platforms. The Makefiles or project files for the Windows platform are also included. For other platforms, it includes platform specific scripts showing how to compile the example code. Network administrators can link their application GUI, CLI, or embedded application with these files and libraries. You can download the APIs from Cisco.
