Cisco Identity Services Engine 2.6 patch 3.Once integrated with ISE, the SMC will learn the user session information (IP address/username bindings), Static TrustSec mappings and Adaptive Network Control (ANC) mitigation actions for quarantining endpoints. Here are a few more of the many benefits you will gain when you implement Cisco Stealthwatch.This post describes the steps to configure Cisco Stealthwatch Management Centre (SMC) and Cisco Identity Services Engine (ISE) using pxGrid. Knowing that you have a top of the range security system constantly working across your extended network can give you real peace of mind as the constant threat of an attack can be extremely stressful. Traffic is monitored automatically so when questionable behaviour occurs you know about it immediately and you have all the information needed to solve the problem. Stealthwatch leverages network telemetry to increase visibility and context into all of your users, a feature that no other security service performs as efficiently.īecause it uses entity modelling you can confidently detect threats, data exfiltration (unauthorised transfer of data) and much more. It’s impossible to know which devices are infected with malware without security like this in place.

This is an invaluable tool to keeping your organisation secure from threats because as time goes on, more and more devices will be connecting to your cloud 63 million new devices will be attaching to enterprise networks every second by 2020 (Gartner). When Stealthwatch is activated you can attain an extremely high level of visibility into network and cloud traffic in a matter of minutes. Where Stealthwatch beats many other security services is the visibility it gives the user. It uses advanced entity modelling and multilayered machine learning, constantly identifying who is on the network and what they are doing, and can detect anomalous behaviour in real-time to identify threats. The enhanced network telemetry from the latest Cisco routers and switches is collected by Cisco Stealthwatch Enterprise.

With Cisco Stealthwatch and its enhanced analytics capabilities, you can better understand whether encrypted traffic on the network is malicious. Clearly a tool to monitor all this traffic is vital as the volume of cybercrime every year is increasing exponentially. 70% of cyber attacks will use encryption in 2019 according to Gartner. But although you may use encryption to protect data and privacy, attackers use it to conceal malware and evade detection by network security products.Ĭurrently, around 55% of traffic through networks is encrypted, this is expected to rise to around 75% by 2019 ( NSS). Now they are using this discovery to release a new technology known as Encrypted Traffic Analytics (ETA). Encryption is important in security. In 2016, Cisco researchers discovered that malware leaves recognisable traces even in encrypted traffic. Stealthwatch prevents this from happening.īelow is a video which explains how Stealthwatch Enterprise works. In the past, hackers have used crafted self-signed certificates that use the names of legitimate businesses or individuals in an effort to obscure the nature of the malicious traffic. A self-signed certificate is an identity certificate that is signed by the same entity whose identity it certifies which can obviously be a security issue. It also searches for things such as self-signed certificates and other signs of sloppiness or bad intention. By reviewing this information, Stealthwatch can make decisions on a file based on its destination or origin.

When a computer communicates with another foreign device such as a modem, a handshaking process will take place in order to establish rules for the communication. Handshaking in technology is similar to what you might guess it is. One way it can uncover shady files is by reviewing unencrypted handshake patterns for known undesirable destinations. Stealthwatch uses several different techniques to uncover any undesired files or malware with some being relatively simple. This contextual information provides visibility and analytics giving you the ability to identify and prioritise emerging threats across the extended network. Now, you can detect threats that have bypassed existing security controls and identify data exfiltration to legitimate cloud services. The advanced security analytics allow you to have deep visibility into both web and network traffic. So, Cisco Stealthwatch can get additional contextual information to identify and prioritize new and emerging threats across the extended network.
