Slacker or hacker? | The Register

According to a recent study, the vast majority of insider IT sabotage is carried out by employees – or ex-employees – who have already showed signs of concerning behaviour such as tardiness, truancy, arguing with colleagues, and poor job performance, according to US researchers.

The findings come from a five-year insider threat study by researchers from Carnegie-Mellon University’s CERT Coordination Centre and the US Secret Service The study- which ought to worry anyone who has difficulty getting into the office on time – 80 per cent of the insider attacks studied were carried out by people who were already known to be disgruntled, but were poorly or ineffectively dealt with by their managers or employers.

Lesson: develop a written policy for addressing and terminating disgruntled employees. Don’t wait until a crisis develops.
