Recently needed to look into multiple vendors for PCI Compliance and all the big players want in excess of £50k (RRP) to get an appliance to handle all the logs as the PCI Compliance requirements are quite demanding if you do these checks manually.
There are many SIEM solutions available however I was impressed with the free offering from Splunk which can be used to centralize secuirty data from multiple Cisco solutions.
A SIEM is a Security Information and Event Monitoring tool and its just a software solution to sorting information and able to identify and react to events.
Splunk have a extensive application library which has been developed by customers and Splunk engineers.
They seem to be staying current as they have support for Cisco ASA SourceFire which hasn’t long been released.

You can also do searches for Usernames or IP Addresses across multiple Cisco Devices to find all information in one place:
Here you can find the Cisco Security Suite so you can install into your Splunk installation:

If you happen to have a team of developers as I do then it shouldn’t be too much work to customize for your system/setup.
