If Bruce Springsteen did computer security, he would definitely excel at performing Incident Response. Choicepoint, Lexis-Nexis, Bank of America, and then several thousand unnamed victims. I am curious, how many companies in the Fortune 500 are currently hosting a digital cocktail party for foreign intruders?
They say:
Every major financial institution has been exploited by attackers. All outsourced software is being made with backdoors. Every developed nation is creating cyber-warfare capabilities. Firewalls, IDS, and anti-virus are not as effective as consumers thought. There are hundreds of non-publicly available exploits in use right now. 5% of all people are innately evil. Hmmm.
How do we confirm any of these if our incident response skills are not as advanced as the adversary?
There are too many safe harbors for attackers to launch attacks without regards to their own well-being. As long as these safe harbors exist, bad things will happen. Paying for remediation is like buying a very expensive candle. You light it, it looks pretty, you are glad you have it. But when it burns out, you have nothing. At the end of 90% of the remediation efforts companies implement, the attackers regain their foothold.
Hey Uncle Samplease spend less brain power trying to legislate and regulate information security, and more time using diplomatic channels to alleviate the onslaught of the attacks coming from the safe harbors of the world. Could you at least send an official "time out" request to attackers in Russia and China during Christmas and Easter?
Attribution for online incidents is getting more difficult. We are having more difficulty determining who is perpetrating intrusions into US firms, primarily because of self propagating intrusions.
We need international cooperation to solve international problems. Russia, Romania, China - feel like pitching in?
Recently, I saw a situation where a company had outsourced their customer service application at a web-hosting facility and it was compromised by the W32.Spybot.Worm. Disaster ensued. I am witnessing very costly responses, with the loss of client data being of critical concern.
I have responded to over 50 computer intrusions in the last 4 years. Anti-virus warned of eight of these events. I think the technology that tries to protect us from an infinite amount of signatures may have to change its marketing to "We do the best we can, and protect you from being low-hanging fruit." I cannot wait to hear the AV companies say they have functional flow signatures as well. Then we will not be able to remotely administer our systems.
In September of 2005, an attacker had 11 portable executable files in his grab bag arsenal. Guess how well anti-virus did detecting this malicious code. 0-11. Why? Well, it will be a long time before AV products flag Microsoft tools as viruses or malware.
After review of the system time/date stamps, we noticed anomalous activity potentially accessing 50 credit card files. The indicators of compromise were all originating from foreign domains. Are we storing anything encrypted nowadays? And if so, in how many locations is the encrypted data stored on the same media in an unencrypted manner?
I think it's time for companies to continue their proactive stance on security, but couple it with a reactive approach and even be "proactively reactive" (some strange way, that makes sense to me)
I've witnessed a number of panicked customers when they find out they've been compromised. Plan first, to include planning your reaction to incidents.
Wouldn't it be cool to develop an automated technique for companies to capture necessary data immediately following an incident before the audit trail is unintentionally/intentionally corrupted by poor incident response techniques?
