Increasing the Cost of CompromiseBy Mike Rothman
It seems to be all threat intelligence all the time in the tech media, so I might as well jump on the bandwagon. My pals Wendy Nather of 451 and Jamie Blasco of AlienVault recently did a webcast on the topic. Dan Raywood has a good overview of the content. Wendy does the analyst thing and categorizes the different types of threat intelligence. She points out that sharing is taking place, but more slowly than it should. Jamie then makes a compelling case for why everyone should share threat intel when possible. Shared intelligence increases the cost of compromise.
…by removing the secretive aspect, (i.e vendors keeping their threat intelligence close to their chests and monetising it – instead of making it freely available) we can force attackers to raise the bar and spend more and more money on their infrastructure, which decreases the return on investment for cyber criminals.
Attackers make crazy money leveraging their tactics. They can buy an inexpensive attack kit (with Bitcoins) and use it a zillion times. If you aren’t talking to your buddy, you don’t know what to look for. If you don’t have a list of C&C nodes or patterns of exfiltration, then when they hit you it won’t immediately raise an alarm. And you will lose.
By sharing information we can force attackers to change their attacks more frequently. They will need to turn over botnet nodes faster. Let’s cost them more to do business. Can we make enough difference for them to give up and stop attacking? NFW. They will still make a ton of coin, but over a long enough period this kind of information sharing can get rid of less sophisticated attackers who would make more money doing something legit – you know, like gaming search engine results.
