Unfair policies prompt most employees to break company IT security rules, and that could lead to lost customer data, a Cisco study found. The first part dealt with common employee data leakage risks and the potential impact on the collaborative workforce. More than half of the employees surveyed admitted that they do not always adhere to corporate security polices. Of the IT respondents who dealt with employee policy violations, one in five reported that incidents resulted in lost customer data, according to the Cisco study.
