As we informed the teams about the vulnerabilities on their systems, and included the trend of how long remediation was taking, we encountered an interesting side effect: The metrics had spurred the teams to try and outperform one another This is discussed in more detail at the end of the case study

The Cisco Security Incident Response Team (CSIRT) is a sister to the Audit Team As the name implies, this team is responsible for handling more reactive security tasks, such as incident response, while the Audit team handles more proactive security tasks, such as compliance audits Of course, this is an oversimplification, because both teams perform proactive and reactive security tasks, and some overlap occurs between the teams A major task for the CSIRT team is to monitor botnet activity on the internal network via a network monitoring tool called NetFlow Data is fed to this tool via a SPAN port on each datacenter switch A SPAN port is a port whose purpose is to mirror the data flowing across all the other ports on that switch (SPAN stands for Switched Port Analyzer, but this is Cisco s specific name for this functionality Other vendors provide this same port-mirroring ability with their own name for the feature) So in a nutshell, all the traffic on every datacenter switch is mapped to a port on that switch, and all that traffic is sent through a series of NetFlow filters that recognize and identify botnet activity Over time, CSIRT has discovered a variety of malware, including botnets, on our internal network As these malware-infected hosts are identified, they are not allowed to route traffic on the network via a technique commonly called BGP Blackholing CSIRT worked with the network team to create an application that can easily deploy instructions to our routers to ignore traffic from these hosts (For more information on this technique, go to wwwciscocom/web/about/security/intelligence/worm-mitigationwhitepaperhtml) With these tools in place, the CSIRT team began detailed tracking of malware and botnet activity, kicking infected hosts off of the network and not allowing them back until the sysadmin said the infection had been removed from the hosts and that the hosts had been patched against reinfection Hosts that were reinfected were repetitively denied access Figure 4 shows how this program ran over the course of two years You ll notice a gradual decrease in activity over the first year and a half, with a small increase in April 2009, followed by another decrease When this project began in February 2008, a large information awareness campaign was associated with it The campaign was designed to inform our lab administrators that Cisco did have malware and botnets, and that entire lab networks had been removed from the Cisco network until they were fully patched The program was largely successful; malware activity decreased in eight months from a high of more than 1000 botnet-infected hosts, to a low of 50 botnet-infected hosts But after that time, the awareness campaign ended, and after four months of very few issues, the numbers started increasing again in February 2009 It seems that something must have happened to lower the total of botnet-infected hosts (perhaps a second awareness campaign ), but that s not what really happened

Cisco, like most large organizations, has a very large and distributed workforce Unknown to the CSIRT team, the Network Operations team (NDCS) had been upgrading many corporate interconnection links from 1GB to 10GB A ten-fold increase in bandwidth is usually a very good thing, but while performing the upgrade, the NDCS team neglected to reconnect the SPAN port for some of the links In effect, this made our monitoring systems blind to traffic handled by those links As for the metrics, it made it look like the CSIRT team was being very effective at addressing the malware and botnets The CSIRT team discovered this four months later when they saw botnet traffic on a filter on a different network segment than the source of the traffic That traffic should have been detected by a filter on that network segment After reconnecting the SPAN ports so the filters could review the missing traffic, we saw a huge increase in malware activity Lesson Six: Create a sanity check on automated metric-generating processes Automation is absolutely essential to managing and maintaining an enterprise network, and automating data collection and analysis is just as essential In this case, an automated flow that had been running for over a year fell out of the total group of flows that CSIRT was measuring Although a number of mechanisms were in place to determine whether the NetFlow collectors were functioning correctly, no mechanism was used to determine whether a NetFlow collector was up, but not doing anything If all of our NetFlow collectors had been dropped, it would have been noticed immediately But we lost only a few, so although the system was broken, it still appeared to be functioning correctly This was an easy issue to fix, but it made us reexamine all our automated processes to look for gaps in how they functioned that could lead to an incorrectly generated metric
