Previously undisclosed intimate details such as sexual preferences and orientation will have a social impact on the unfaithful and close family members. Personal impact has serious consequences spanning beyond financial impact such as strained family relationships, reputational damage and adverse health consequences (eg: stress).
Organisational policy is there to ensure that staff behave in line with organisational expectations. Just as staff are not allowed to take bribes, turn up intoxicated to work, staff are expected to ensure that their behaviour online do not tarnish the organisation’s reputation. When allowing personal use of corporate systems organisations must consider the external impact of the staff member’s actions.
An organisation’s security policy must reflect the level of professionalism expected by senior management and importantly their customers. Policy, communication, education, transparency (and incident response/public relations) must be in place to protect all parties involved.
After all, staff that behave badly is a reflection on the organisation as a whole.
