Security Breaches: Ineptitude Goes a Long Way
When it comes to security breaches, "never ascribe to malice, that which can be explained by incompetence" is a dictum IT security managers should take to heart.
While organizations scramble to protect themselves against the next big TJX-style data breach, they're overlooking another risk: social networking. Nearly every organization has an in-house blogger – officially or not.
It doesn't have to be a Mini-Microsoft – an insider blog often critical of the Microsoft – to pose problems. An enthusiastic employee who's not well-versed on corporate policy, a developer on public message boards, or even a personal blog where the employee occasionally discusses work all pose risks.
The July 2007 survey gathered 308 responses from U.S. companies with 1,000 or more employees. Forrester found that more twenty percent of those surveyed had investigated "the exposure of confidential, sensitive or private information via a blog or message board posting in the past 12 months."
"Security and IT professionals are just starting to wake up to blogs and message boards," said Keith Crosley, Proofpoint's director of market development. "The main concern is still outbound email, but these other forms of messaging and networking can't be overlooked."
Careless Employees Can Be as Dangerous as Malicious Ones
Usually, the intentions of employees aren't malicious, just careless. AOL's data leak of last summer provides a case in point. AOL posted information relating to search queries on its now defunct research site, violating the privacy of 658,000 subscribers. While AOL tried to protect users' identities, replacing user names with numbers, it was relatively easy to figure out who a large number of these people were because they often searched for themselves, their family and friends, and things in their neighborhoods.
AOL certainly wasn't malicious, just incredibly careless. AOL figured that this information would be useful to researchers, and they certainly didn't intend to violate customers' privacy. They just didn't think things through, leading to a huge scandal, plenty of public humiliation, the loss of a number of customers, lawsuits, and the firing of three employees, including its CTO.
According to G. Oliver Young, an analyst with Forrester Research, the time to start worrying about content control is even before an employee enters the company. "If job candidates have questionable content on their MySpace or Facebook pages, it should raise flags," he said. It's common now for employers to check those sites before a person is even offered an interview.
According to Proofpoint's Crosley, the scope of the problem is much larger than most people realize. "For every high-profile data-leak event, there are probably hundreds of smaller ones," he said. These aren't publicized. They're handled internally, and the result is often a termination.
"When H.R. starts looking at an employee's online behavior, it's serious," Crosley said. In the past, employees worried about organizations nitpicking about their browsing habits. After all, as work bleeds into the personal lives of knowledge workers, many argue that it's perfectly reasonable to do some personal business during work hours. Similarly, the stress of knowledge jobs makes it equally acceptable to take a ten minute break where you check, say, sports scores.
What Proofpoint has found is the vast majority of employers don't worry about time wasting. "If H.R. is monitoring an employee's online behavior, it's almost always related to data leakage or the theft of confidential information – not time wasting. The productivity concern is a much lower-tier issue. It won't cost you millions of dollars in shareholder value."
Data leaks and data theft don't necessarily involve online behavior, though. When the VA had its big data-leak scandal, it was due to a single IT employee losing a laptop. The probability of similar events occurring rises proportionally to the lowering costs associated with portable storage.
With multi-GB USB drives on the market now – at low price points – VA-sized risks occur each night as your employees leave the building with GBs of information in their pockets.
"External storage and peripherals need to be managed just as carefully as sensitive applications," said Philippe Honigman COO and president of the U.S. operations for SkyRecon Systems SkyRecon Systems. "Most USB drives are delivered without built-in authentication or encryption, and the majority of organizations are simply ignoring the risks associated with these devices."
