State of IT Security
Insurance Experts' Forum, September 30, 2011
IBM released the results of its latest “X-Force” report, which regularly looks at online security threats from across the planet. There's bad news and good news.
The bad news is, unfortunately, attackers seem to be getting smarter. The good news is we're getting smarter as well.
This year, the big threat is something called “whaling,” a scaled-up version of “phishing.” Put your executives on notice, as whaling targets high-level people in highly visible organizations—ripe targets for stealing sensitive data.
Whaling is a type of spear phishing that targets "big fish.” These targeted attacks are often launched after careful study of a person’s online profiles has armed an attacker with the information needed to create a compelling phishing email that the victim will be fooled into opening.
In addition, there's more of what IBM calls “Advanced Persistent Threats,” coming from teams of professional attackers motivated by a desire to collect strategic intelligence. They have been able to gain and maintain access to critical computer networks through a combination of stealth, sophisticated technical capabilities and careful planning.
The other threat zone is in mobile, the report observes. The many smartphones and tablets being brought into the enterprise are threatening the security of corporate networks. The study projects that 2011 will see twice the number of exploit releases that occurred in 2010. X-Force has observed that many mobile phone vendors do not rapidly push out security updates for their devices. In addition, there has been a rise in the amount of malicious software targeting mobile phones, often distributed through third-party app markets.
So now the bad news is out out of the way; on to the good news. For example, the X-Force study reports, “the first half of 2011 saw an unexpected decrease in web application vulnerabilities, from 49 percent of all vulnerability disclosures down to 37 percent.” This is the first time in five years there has been a decrease in such issues.
Browsers have gotten better as well. High and critical vulnerabilities in web browsers were at their lowest point since 2007, despite an increasingly complex browser market, the report notes. Plus, major botnet operators are taken down and off-line by law enforcement officials, so the report shows a trend in the decline of spam and more traditional phishing tactics.
And, here's some really good news: spam is on the wane. After years of consistent spam growth until the middle of 2010, there has been a significant decline in spam volumes in the first half of this year.
