6. Conduct A Thorough Forensic Analysis. Likewise, don't expect breach investigations to be cheap. But short-term savings--skimping on conducting a thorough forensic analysis after a breach, for example--can have long-term repercussions, as Nortel discovered. "The ultimate irony is that the reason that most companies do not complete extended breach scans is the price, which the CEOs and CFOs are reluctant to green-light," said Logan. "However, if one looks at the financial and other fallout from this type of breach--fines, compliance issues, loss of customer trust, and damage to the brand--this type of intensive breach prevention makes sense."
7. Expect Greater Accountability Nortel executives notably failed to disclose the breach, even to potential buyers of the company or its assets. But according to Corero's Roiter, "We expect that the new SEC guidelines will result in more disclosures, such as the recent revelation of the VeriSign breach in 2010." Notably, VeriSign's SEC filing revealed that the company had suffered a data breach that may have compromised critical information relating to the Internet's domain name system. Accordingly, executives who want to avoid having to report these types of breaches should invest in "aggressive monitoring to detect outbound traffic and suspicious activity in the event of a breach," he said.
8. Defend Against More Than China. Was the attack against Nortel executed by someone with ties to China? That's possible, but for corporate information security programs, does the answer even matter? "It's very hard to prove a Chinese involvement. Yes, the data might have been transmitted to an IP address based in Shanghai, but it is possible that a computer in Shanghai has been compromised by, say, a remote hacker in Belgium," said Graham Cluley, senior technology consultant at Sophos, in a blog post "But let's not be naive. Of course, there are Chinese hackers. But there are also British hackers, and South African hackers, and Canadian hackers, and Italian hackers," he said. In other words, anyone from nation states to malicious insiders could be trying to steal your business's data. Be prepared.
