Insider Threats
An insider threat is any person who has or had authorized access to or knowledge of an organization’s resources, including personnel, facilities, information, equipment, networks, and systems.
Understanding the risks of Insider Threats
Insiders can exploit their access and understanding of your network to steal data, compromise systems, and cause significant harm. Insider threats possess the potential to cause damage that often exceeds that of external attackers.
What is an example of an Insider Threat?
When a former employee retains access to systems they become a potential threat to the organization. The reason for this is that they have the means and potentially the motive to execute on the threat. It's for this reason that employee access to systems needs to be clearly documented, with offboarding procedures on how to revoke the access.

What can you do to protect your organisation from Insider Threats?
IT security is a collective effort, and everyone in the organization plays a vital role. You can contribute by trusting your instincts, using data classification mechanisms, and actively promoting cyber security awareness
Trust your instincts
Classify your documents
Foster a culture of security
If something seems off, go with your gut and report it. If you notice someone unexpectedly working long hours, displaying excessive curiosity about your sensitive projects, acting suspicious or showing resentment towards the organisation. These are signs of a potential insider threat.
Classify documents by sensitivity and enforce least privilege access to protect sensitive information from potential insider threats. By prioritizing document protection and access control, you are effectively putting up internal walls making it more difficult for an insider threat to inflict damage or acquire information.
Foster an atmosphere of positive communication and ethical behavior in your workplace. Encourage your colleagues to make security a top priority and stress the significance of promptly reporting any concerns or potential threats they come across.
