ISE 2.1 and WSA pxGrid Integration with CA-Signed Certificates

This blog post is going to be going over integration ISE 2.1 and WSA via pxGrid with CA-signed certificates. I personally like using CA-Signed certificates for my deployment because if I ever need to rebuild an ISE instance or pxGrid client, it's extremely easy to get it up and running again with a CA-signed certificate.

ISE 2.1 - Configuration of AMP & ISE Integration

This post is going to go over the integration of ISE 2.1 and AMP for Endpoints. ISE 2.1 introduces the concept of a "Threat Centric NAC" which allows you to configure vulnerabiltiy and threat adapters to send high fidelity Indicators of Compromise (IoC), Threat Detected events, and CVSS scores to ISE so that threat-centric access policies can be created to change the privilege of the endpoint accordingly. 

StealthWatch 6.8 and ISE Integration with CA-Signed Certificate

In this blog post, I'll go over StealthWatch and ISE integration with pxGrid. With this integration, ISE will share contextual information such as username and device information with StealthWatch and it adds the ability to do rapid threat containment to quarantine misbehaving endpoints. I'm going to use a CA-signed certificate in this post and later I'll add a post with self-signed certificates. 

StealthWatch ProxyWatch with WSA

In this blog post, I'm going to go over ProxyWatch with StealthWatch. Many enterprises utilize proxies to protect their networks. They provide protection at the cost of visibility to other security solutions. ProxyWatch is a licensed feature that allows StealthWatch to see the translated address and associate it with the other side of the proxy conversation which provides more accurate troubleshooting and forensics. It's a bit like NAT stitching for proxies. 

StealthWatch Introduction

Lancope was founded back in 2000 and is a leading provider of network visibility and security intelligence to protect enterprises against today's top threats. The StealthWatch System uses NetFlow, IPFIX and other types of network telemetry to detect a wide range of attacks from a variety of threats including APTs, DDoS, zero-day malware and insider threats. Lancope was just recently acquired by Cisco late last year but the company itself had a very close relationship with Cisco prior to that and thanks to that relationship, it integrates quite well with a variety of existing Cisco solutions. In this first post, I'm going to dig into some of the components of the StealthWatch System.

ISE 2.0 - Profiling

In a perfect world, you could authenticate your hosts onto the network with either dot1x or going through a guest portal but the reality is that not every device connected to your network will have the ability to navigate the guest flow or utilize dot1x. Unfortunately, most of us don't live in a perfect world and have to connect devices to our networks such as phones, IP cameras, printers, badge readers, access points, etc so for that reason, profiling comes in. What ISE will do is gather a series of attributes from the NADs that the endpoints are connected to and based on those collections of attributes, ISE is able to make a determination of what kind of device that endpoint is

ISE 2.0 - Hotspot Policy

In this post, I'm going to configure Hotspot access. Hotspot access is a little different than regular guest access in ISE. The use case for Hotspot is where you might want to allow guests to access the internet without issuing them credentials or directly identifying them but still have some level of control. An example of this is if you own a chain of retail stores and you want to give your customers guest access to the internet and you don't want them to have to self-register or disclose information about their identity. Hotspot would be the solution to provide access. With Hotspot access, you can have a branded portal for marketing reasons, have the user accept an AUP for legal reasons, redirect them to your company's page or maybe a webpage with the latest deals/coupons, and you can even have them enter an access code that you have displayed in this location to reduce random connections to the network from users not location in the establishment.
