CX and Cisco Prime Security Manager (PRSM, pronounced “prism”) are closely related. They share the same user interface, so that your experience in directly managing a CX device is easy to translate into managing multiple devices in Cisco Prime Security Manager.
Thus, these release notes and the product documentation cover both the CX platform and the Cisco Prime Security Manager device management software, as well as ASA device configuration to the extent that you can configure the ASA in PRSM. When reading the release notes and the product documentation, keep the following in mind:
- PRSM Multiple Device mode refers to the multi-device management application, which you can use to manage more than one CX device and ASA devices. Where a feature applies to this platform only, we explicitly state that it is for Multiple Device mode.
- ASA CX (or CX) only, Single Device mode, or PRSM Single Device mode refers to the management application that is hosted on the CX device itself. You can use this application to configure that single device only. Thus, functions that relate to managing multiple devices, such as the device inventory, do not appear.
Tip You can find both the AD Agent and CDA software on Cisco.com on the following path on the DownLoad software page: Downloads Home > Products > Security > Firewalls > Adaptive Security Appliances (ASA) > Cisco ASA 5500 Series Adaptive Security Appliances > Cisco ASA 5580 Adaptive Security Appliance > Adaptive Security Appliance (ASA) Software. The table includes direct links to the pages.
You can use this application as a replacement for Cisco AD Agent. Although the agent configuration differs, the method for identifying the agent in PRSM or CX is identical to identifying the AD agent.

If supported, Cisco Prime Security Manager allows you to configure a single-sign-on (SSO) relationship between PRSM and other applications. An SSO relationship allows you to log into the other application, then directly access PRSM from within that application without needing to log into PRSM. Your username/password for the other application suffices for PRSM authentication.
Note Cross-launch, but not single sign-on or object import, is supported in Cisco Security Manager 4.4.
- Single sign-on cross launching.
- Export network, network group, service, and service group objects for import into PRSM.
For the most part, you can use IPv6 addresses in CX and ASA policies and configuration settings. However, in the following cases, the ASA will allow IPv6 addresses, but you cannot configure or use them with PRSM:
Your other option is to import the ASA in monitor-only mode. In monitor-only mode, PRSM does not discover the ASA configuration, nor does it manage it. You will not be able change the configuration through PRSM. Monitor-only mode is a good option if you want to use other applications to configure the ASA, such as ASDM or Cisco Security Manager.
Tip Cisco provides an off-line tool that will convert the unsupported service object commands, and the ACLs that use them, to the required style. You can use the tool to convert an ASA configuration, then verify it yourself before you manually apply the changes to the ASA. You can then add the device to the PRSM inventory. The tool is called CSM to PRSM Migration Tool and is available as a download from the Cisco Prime Security Manager software download page. The readme file in the download includes instructions on using the tool.
You can enforce Safe Search settings on certain web sites. By enforcing Safe Search, you prevent users from relaxing search results to include inappropriate or explicit materials. If you enable an access policy to enforce Safe Search, search URLs are rewritten to ensure strict Safe Search settings. If CX does not support rewrite for a search engine, that engine is blocked for any traffic flows that match an access policy that enforces Safe Search.
Note The behavior described here applies to 9.2(1.1) Build 48 only. In subsequent releases, license assignments are correctly made for profile-based features. However, the requirements for valid AVC and WSE licenses when using those features for traffic matching criteria remain applicable.
In 9.2(1.1) Build 48, all valid licenses defined on a CX device are imported when you add the device to the PRSM inventory. However, the imported licenses might not be assigned to the imported device. In addition, existing available feature licenses that you uploaded to PRSM might not get automatically assigned. Please be aware of the following rules:
- If the imported device uses application or application type specifications in the traffic matching criteria of any policy, OR there are such policies defined in the Universal CX access policy sets in PRSM, you must have an available AVC license, either a non-evaluation license defined on the device, or an available evaluation or non-evaluation license in PRSM. During import, the AVC license is automatically assigned to the device. Import will fail if you do not have an available AVC license.
- If the imported device uses URL objects in the traffic matching criteria of any policy, OR there are such policies defined in the Universal CX access policy sets in PRSM, you must have an available WSE license, either a non-evaluation license defined on the device, or an available evaluation or non-evaluation license in PRSM. During import, the WSE license is automatically assigned to the device. Import will fail if you do not have an available WSE license.
- If the imported device uses web reputation objects in any policy, you can import the device even if you do not have the required WSE license. However, if you do have a WSE license, the license is not automatically assigned to the device. However, if you also use URL objects, the WSE license will be assigned due to that fact, and it will cover web reputation features.
- Next Generation IPS licenses are never assigned to the imported device. You must always go to the Licensing page and assign the license, or IPS filtering will stop working on the device.
You can view the web interface in English and Japanese. To get Japanese, change the preferred language setting in the browser to Japanese. You will get English for all other language settings, although dates and times might be formatted based on the selected language.

- PRSM now assigns licenses correctly during device import for features used through profile objects.
- A new CX traffic event, TLS Abort, which is now issued for decryption failures instead of Flow Deny. These events can help you isolate and evaluate decryption processing failures associated with decryption policies.
- The Updater window now applies to all updates, not just engine updates.
- URL category and web reputation are now available for TLS/SSL traffic even if you do not enable decryption. Access policies that use URL filtering or web reputation filtering will now apply correctly to undecrypted TLS/SSL connections.
- The following new or changed CLI commands:
- Support for Internet Explorer 9.0 for the web interface.
- Support for Mac OS X Mountain Lion, and the Safari browser, as a client platform for the web interface.
- A new web interface design, moving many policies to the new Configurations > Policies/Settings page. Some policies allow you to edit values directly in the policy table.
- Improved change detection when multiple users are defined for the system. You will see notifications if another user is editing the same item you want to change, so you can avoid conflicts.
- You can now import your own end-user notification pages.
- The methods for applying licenses has been simplified, especially in PRSM, where assignments are no longer based on device group. Licenses are no longer automatically committed; you must commit and deploy them the same way you do for policies.
- You can now configure Cisco network participation so that the systems send attack and usage telemetry data to Cisco.
- Next Generation IPS filtering, including automatic signature updates, global settings, dasbhoards, events, and reporting. You configure IPS filtering directly in access policies. Next Generation IPS filtering is a separately-licensed service; the device includes an evaluation license.
- New decryption settings that let you relax decryption processing requirements, so that you can ignore untrusted certificates or TLS handshake failures and allow those transactions without decryption. Options are under the heading Deny Transactions to Servers , and are Using an Untrusted Certificate: On/Off and If the Secure Sessions Handshake Fails: On/Off .
- Interface role support: you can configure policies for specific ASA interfaces. CX policies can filter on the interfaces used by transactions; ASA policies are applied to the matching interfaces.
- You can configure access policies to warn users of undesirable web site access, rather than simply drop the connection. Users can accept your warning and proceed to the site on their own responsibility. Use this type of policy for URL filtering on categories where some of your users might have legitimate reasons to access a questionable site.
- You can configure access policies to enforce safe search, which prevents users from relaxing safe search restrictions in their search engines.
- You can configure access policies to rate limit (police) matching traffic, throttling connections that would otherwise overwhelm the network.
- Support for ASAs that do not include CX modules, including the 5510, 5520, 5540, and 5550 models, as well as all models that support CX. Although multiple-context mode is still not directly supported, you can add multiple context ASAs that contain CX devices to the inventory. You can also add ASAs configured as high-availability active-standby pairs. Minimum ASA Software release for all models is 9.1(3).
- You can now import ASA devices in monitor-only mode, so that you can view dashboards from the ASA, but not configure it. This mode is useful if you use a different application, such as ASDM or Cisco Security Manager, to configure the ASA, but you want to use PRSM to configure the CX module contained in it.
- Deleting a device from the inventory is no longer automatically committed. You must commit changes to complete the deletion.
- The ability to create device overrides for network and interface role objects, which allows you to define different content for an object when it is used on specific devices. When you add a device to the inventory, you will have the option to create overrides instead of renaming objects if there are naming conflicts with objects that already exist in the database.
- Device groups are eliminated and policy sharing is based directly on individual devices. There are also separate device and repository views, so that you can configure and assign shared policies separately by viewing policies rather than devices, or you can do this by finding the device whose policies you want to share. This gives you flexibility for viewing policies and configurations the way that suits you best.
- Several policies that used to be global are now per-device, so that you can deploy different policies among managed devices. Now local policies include AD agent, decryption settings, authentication settings, and packet capture settings.
– Network, network group, service, service group, user identity group, and time range policy objects. In previous releases, the network and service objects would be discovered, but in this release, you can create and edit the objects and deploy the changes back to the ASA.
– ASA extended access policies. These policies are shown on the same tab as CX access policies so that you can clearly see the relationship between access control between the devices. Standard, Ethertype, and web ACLs are not supported, nor are TrustSec security groups on extended ACLs.
– Traffic redirection to the CX module, and ASA logging and syslog server settings, continue to be supported, but you can now find these policies as tabs on the Configurations > Policies/Settings page.
- There is a new ASA Traffic dashboard where you can view top sources, destinations, and services for the ASA.
- In deployment and change history, you can view CLI previews and transcripts of the communication between PRSM and the ASA.
- PRSM now recognizes out-of-band changes (changes you make to the device configuration outside of PRSM control), and you can configure PRSM to warn about or overwrite these changes.
- Event viewer changes to make event management more robust. CX devices can maintain an event backlog if communications with PRSM are unavailable.
Use the web interface or the system upgrade command to apply the 9.2(x) upgrade to a system running 9.1(x) or 9.2(x). Specific instructions are in the documentation cited in Installation Instructions.
- Starting with 9.2(1.1) Build 48, CX and PRSM will now enforce correct masks for network specifications in all types of network object. Please evaluate all network specifications in all objects to ensure you have entered the correct network masks prior to upgrading to 9.2. For more information, see Preparing Service Objects for Upgrade from 9.1(x) to 9.2(1.1).
- If you upgrade from a 9.1(x) release, any ASAs that you are managing will be placed into monitor-only mode. If you want to continue managing the ASA configuration with PRSM, open the device inventory by selecting Device > Configuration and go to the Repository view. On the Overview tab, look for the information icon in the Last Deployed column; click the icon and then click the Import link to import the device’s configuration. For information on the general steps, see Upgrading from 9.1(x) to 9.2(x).
- Because 9.2(x) recognizes devices configured for high availability (HA), whereas older 9.1(x) releases did not, you must first delete any devices that are configured for HA from the PRSM inventory prior to upgrade. After upgrade, you can add these back. For information on the general steps, see Upgrading HA Devices from 9.1(x) to 9.2(x).
For information on the supported upgrade paths, see Cisco CX and Cisco Prime Security Manager Compatibility at http://www.cisco.com/en/US/docs/security/asacx/compatibility/cx_prsm_comp.html .

Note This behavior is corrected in 9.2(1.2). When upgrading to 9.2(1.2), the network addresses will be corrected automatically based on the mask/prefix. Thus, your system’s policies will be enforced the same way they were prior to upgrade, and the CX device will not drop traffic.
Prior to 9.2(1.1), PRSM did not validate network masks for IPv4 network addresses, or prefixes for IPv6 address, when added to CX network objects. Starting with release 9.2(1.1), correct masks/prefixes are now enforced. If you entered the incorrect mask/prefix in any CX network object, after upgrading to a CX device to 9.2(1.1), you will see the following symptoms:
- The CX device will immediately drop all traffic until you find and correct the mis-configured objects.
- When you go to the CX Event Viewer page, you will get the message “Error retrieving event catalog.”
Thus, you might want to check these objects before performing the upgrade. To do so, go to the policy objects page and filter on the slash character, “/”, limiting the search to CX network objects. This will eliminate host and range objects.
Then validate that each network specification has the right mask/prefix, such that none of the bits defined as host bits are set to 1. For example, 10.100.0.0/255.255.0.0 is a correct mask, whereas 10.100.10.0/255.255.0.0 has bits set in the third octet, but the mask defines that octet as being part of the host. Mistakes for masks that do not fall on an octet boundary are harder to identify; for example, the mask in 18.104.22.168/255.255.255.192 defines the last 6 bits as the host portion, but .96 uses one of those bits, and the correct address for the mask would be 22.214.171.124/255.255.255.192.
If you do not fix all problems prior to upgrade, fixing them post upgrade is somewhat difficult, and requires that you download the diagnostics file from the CX device, edit the mgmt-plane.log, and look for messages in the format “ValueError: 10.1.1.0 has host bits set,” where the IP address is the network address defined in a CX object. There will be one message per mistake. However, because 9.2 will not display mistaken entries in the CX object, you will need to edit each object that might have the offending entry, then go to the Changes Pending page and look for the object where the old mistaken entry is listed with the DELETE action. Note the object name, discard changes, edit the object to enter the correct address, then save and commit. You will also have to restart processes on the CX device from the command line. For more details, see bug CSCuj89056 .
Release 9.2 adds configuration support for many ASA features. Thus, when you upgrade to 9.2, existing ASAs in the PRSM inventory are put into monitor-only mode. To move them to managed mode, you need to click the link in the inventory to import the ASA configuration.
Tip If you use another application, such as Cisco Security Manager, to configure the ASA, leave it in monitor-only mode. In managed mode, PRSM will consider itself the owner of supported features, and overwrite changes made by your other application. In general, you should use a single application to manage a device.
Look for an information icon in the Last Deployed column for the device and click the icon. A popup message explains the state of the device. If the message includes an Import link, you can convert this device to managed mode by clicking the link and following the wizard.
Release 9.2(1.1) introduces management of high availability (HA) devices. In 9.1, PRSM did not know if an ASA, and subsequently, its CX device, was configured as part of an active/standby pair with another device. Thus, to manage the CXs, you would import them both to PRSM separately.
Because PRSM 9.2 now treats HA devices as a unit, you should first remove these devices from the PRSM inventory prior to upgrading to 9.2. You can them add them back to the inventory. Following are the general steps.

For changes to the Application Visibility and Control (AVC) signatures, you can look at Release Notes for Application Visibility and Control Signatures, Release 1.1.0.x at the following URL. Although these notes are written for the Cisco Web Security Appliance (WSA) product, these products use the same AVC signatures, so the facts about signature changes also apply to PRSM and CX. Note that these notes refer to behaviors as “granular controls.”
