Cisco Ise Profiler Feed Download

FeedService test connection failed : Feed Service unavailable : SocketException invoking :8443/feedserver/feed/serverinfo?ISE_VERSION=2.3.0.298: Connection reset **Please ensure that the certificate store on ISE has a valid and enabled entry for either the root certificate or the intermediate certificate for the SSL server certificate chain of Cisco ISE feed server. **Please ensure that Proxy settings are configured if needed to reach Feed Server.
Thanks again for everyone's suggestions. I was able to track down the issue with TAC. We found an in-house firewall rule that allowed 8443 to ise.cisco.com but it was using a static IP for Cisco's feed rather than an FQDN lookup. I'm guessing the public IP for ISE's profiler feed changed on 3/17, causing this issue.
Here's the error on the 2.3 side when I try to manually run it:

ISE has by default large set of built-in profiles, but due to large number of devices being manufacture on daily basis, it is required to have profiles for them too. In order to solve this problem, cisco developed a service called profiler feed service.
When a new device is manufactured in market, the profile related to it is created by Cisco partners and Device manufactures, and with the help of ISE Profiler feed service, these profiles are distributed after QA team has passed the quality check.

ISE Plus licenses can be looked at as building on top of the functionality provided by base licenses in that plus licenses do NOT include the functionality provided by base licenses. Plus licensing uses a subscription model because it is providing a feature-set (device profiling, BYOD, etc..) tied to an ever changing landscape (i.e. new endpoints and OS versions are released all the time!). To combat the ever-changing landscape, Cisco maintains a profiler feed service that your ISE deployment will use to stay up-to-date. Below is a list of the most notable functionality you are entitled to when using Plus licenses.
ISE Apex licenses can be looked at as building on top of the functionality provided by base licenses in the same way that plus licenses do. Apex licenses do NOT include any functionality provided by base or plus license types. Like Plus licenses, Apex licensing uses a subscription model because they provide a feature-set (device posturing) tied to an ever-changing landscape (i.e. new endpoints, OS, and application versions are released all the time!). To combat the ever-changing landscape, Cisco maintains a posture feed service that your ISE deployment will use to stay up-to-date. Below is a list of the most notable functionality you are entitled to when using Apex licenses.
Please review the threatfeeds log on your Gateway or Cloud Gateway to see any errors, or issues. For more information regarding External Threat Feeds, please refer to Configuring Email Gateway to Consume External Threat Feeds chapter for the End-User Guide for the version of AsyncOS you have running for your Gateway or Cloud Gateway.
The Profiler Feed service is used to automatically update the ISE profiler database directly from the Cisco website. You can manually update the profiler database by downloading the polices from here (Partner access required). The feed service is automatically enabled when you install a Plus license.
ISE already has a large list of pre-created profiles and since I enabled the profiler feed, it's being updated with new profiles on a schedule. ISE looks at the endpoints with a simple but effective logic: It looks at a series of endpoint attributes that it receives from probes and basically gives each matched attribute a score. In order to match a profile, it needs to meet a minimum certainty score. Profiling should also be balanced with the security controls that ISE puts in place. For example, if you have a IP camera connected and profiled and it only needs to connect to the CCTV server, it should receive a DACL to the port that limits all but the necessary access.
The NMAP utility is incorporated into ISE to allow the profiler to detect new endpoints through a subnet scan and to classify endpoints based on their operating system, OS version, and services as detected by NMAP. The network scan probe is considered an "active" assessment mechanism since it communicates directly with the endpoint to obtain information from the source. The can scan also be triggered dynamically based on policy.
My lab isn't very complicated so I'mgoing to create a very simple policy. The first thing I'm going to do is navigate to Policy>Profiling>Profiling Policies and drill down to Cisco-Device>Cisco-Access-Point and see some of the different profiler policies for each access point:
From the above profiler policy, the certainty factor needs to be a minimum of 30 to fall into the Cisco-AP-Aironet-3600 policy. Some of the checks include the cdpCachePlatform information containing the string "cisco AIR-CAP3602" which would be an indicator that the endpoint would be this model of access point.
The least cisco is a slender salmonid-like fish up to 19 inches in total length. Adult least cisco are distinguished from other adult ciscos of Alaska by the lower jaw, which protrudes slightly beyond the upper jaw when the mouth is closed, and by the pelvic fins, which are dusky to black in color.
Adult least ciscos are generally brownish to dark green dorsally with silvery lower sides and belly. Its dorsal fin is high and separate, while its small adipose fin is placed just anterior to its deeply forked caudal fin. In the ocean, least ciscos have dark spots on their head, back, dorsal, and adipose fins.
Least cisco populations in Alaska may be anadromous, which means they spend part of their life in the ocean and part of their lives in fresh water or non-anadromous, spending their entire life in freshwater. Riverine populations of least cisco appear to spawn between late September and early October. Lake resident populations of least cisco, similar in size to riverine populations, also appear to spawn between late September and early October. Dwarf least cisco, which mature younger and at a smaller size, appear to spawn from mid to late September. Least cisco typically reaches sexual maturity between 3 to 8 years of age. Depending on her size, a female least cisco may release from 10,000 to 80,000 eggs. Whitefish eggs are negatively buoyant and non-adhesive. Eggs are broadcast over substrate composed primarily of gravel, sand, or rock in both lotic (riverine) and lentic (lakes or ponds) environments. The eggs presumably hatch in the spring and the young descend downstream to feed and rear in river deltas, estuaries, and nearly coastal environments of rivers which support whitefish populations.
The least cisco have small superior mouths that are ideal for taking swimming prey above or in front of them in the water. Least cisco also feed on a variety of zooplankton including crustaceans, aquatic insects, and small fishes. Adult least cisco does not feed during spawning migrations.
Anadromous least cisco typically migrates into freshwater systems in late spring to late summer to spawn. Spawning is believed to occur between late September and early October. Least cisco are known to spawn in sections of the Chatanika, Alatna, and Innoko Rivers. Least cisco may spawn in portions or tributaries of the Yukon and Kuskokwim Rivers.
In Alaska, least cisco are found from the arctic coast to Bristol Bay and in most streams and lakes north of the Alaska Range. Least cisco are also found throughout Yukon and Kuskokwim River drainages.
Several studies have been conducted on several species of whitefish, including least cisco populations by a number of agencies over the years. Research indicates that Colville, MacKenzie (Canada), Kuskokwim, and Yukon River populations are quite distinct. Such information is very useful when conducting mixed stock analysis on fish collections of unknown origin.
