The enemy within
by Brian Honan - CEO BH Consulting - Thursday, 21 November 2013.
Too often we read about a security breach that can be linked back to a former employee’s account that was not deleted or disabled when he or she left the organisation. So remember to ensure you remove access to systems for staff that have moved on from the company or have been made redundant.

While it is not comfortable to think of a work colleague being the source of a security breach, it is a real threat and one that needs to be managed properly. Remember, in security as in all parts of life, it is always the people you trust the most that have the potential to hurt you the most.
