There are many SIEM solutions available however I was extremely impressed with recent innovations from Splunk regarding a free Application that can be used to centralize security data from multiple cisco solutions. By definition, a security information and event monitoring system aka SIEM is typically just that; either a good information sorting tool or solution that helps identify and react to events.
One of Splunk’s key market differentiators is their extensive application library developed by customers and Splunk engineering. These applications turn the traditional SIEM into a business enabler to meet specific use cases. Splunk has developed cisco applications in the past however recently face-lifted the cisco Security Application to include Cisco access control (ISE), email security (ESA), web security (WSA), Cisco firewalls, and even SourceFire (both network and only SIEM as of today to support malware aka AMP). This application can link findings with other vendor data such as taking ISE context (IE Joey’s windows 7 laptop on port 1/0/14) and matching it to any captured log by Splunk (For example a McAfee IPS event). This provides a true centralized view of data across a network.
I’ve posted about configuring Cisco Identity Services Engine ISE for a few use cases however have had requests to explain the steps to setup a basic lab. This post serves as a guide to get a basic ISE lab running to test LAN or Mobile devices. My lab uses an Apple Macmini as an ESXI 5.1 server hosting the ISE virtual machine (explained HERE). See the configuration guides for details on configuring a lab.
Virtual Machine Setup: Download the latest ISE .ISO file from cisco.com. Access the ESXI GUI and select New Machine. The recommended specs for a custom New Machine:
Virtual Machine version 7
Linux 5 32 bit
2 virtual CPU
4 gig of memory
60 gig of space – thin provisioning (I find thick isn’t necessary for a lab) Continue reading →
Controlling who and what access your network is a critical element to keep your resources safe from malicious threats. Network Admission Control (NAC) solutions like the Cisco Identity Services Engine (ISE) can police who and what is permitted network access as well as enforce policy for those devices. Examples would be permitting an administrator with a government furnished Windows 7 laptop access to VLAN 10, which holds internal servers, while provisioning a marketing professional’s iPad with VLAN 20 access, which is limited to Internet and email through the use of ACLs.

Lancope enables visibility for security and network performance. Security capabilities focus on identifying insider threats such as botnets, malware and data loss using non-signature network wide correlation of all traffic. Pretty much anything touching the physical or virtual network leaves a footprint known as NetFlow that is investigated for malicious intent and performance statics.
Lancope offers a virtual and physical appliance option for the StealthWatch technology making it easy to build a lab. This post will explain how to build a simple Lancope lab integrated with Cisco ISE 1.2 beta using an Apple Mac mini server hosting vSphere ESXI 5.1 with ASA 5505 firewall. Continue reading →
Today’s threat landscape is loaded with malicious websites, malware and other risks that attack users every nanosecond of the day. There isn’t a single product available that can guarantee protection from cyber threats. Older solutions leveraging static technologies such as signatures are not good enough. The best approach for dealing with advanced threats is continuously monitoring the entire network through layering security technologies. Continue reading →
