Types of Insider Threats

The primary categories of malicious internal activity can be classified into various types. These include:

  1. Malicious Insiders – This type of insider threat involves employees who deliberately and willingly seek to cause harm or damage to their organization through the use of technology. Examples of malicious insiders include those who steal proprietary data, sabotage systems or networks, and create malware or viruses.
  2. Unintentional Insiders – Unintentional insider threats are caused by employees who do not mean to cause any harm but may put their organization at risk due to human error or a lack of security awareness. Examples include accidentally exposing confidential information in emails, sharing passwords with unauthorized personnel, and clicking on fraudulent links in phishing scams.
  3. Data Leaks – Data leaks occur when sensitive information is shared inappropriately outside an organization’s network without authorization from the owner or administrator. Such leaks can result from intentional actions by malicious insiders as well as unintentional mistakes made by untrained staff members that expose valuable data assets such as customer records and financial documents online.
  4. Compromised Accounts – Compromised accounts are another common type of insider threat where user credentials are stolen or hacked resulting in unauthorized access to sensitive information by outsiders posing as legitimate users within the organization’s network.

Insider threats pose significant risks to organizations of all sizes since they often go undetected until it is too late and costly damage has already been done. To avoid these risks, organizations must implement measures such as employee screening processes, secure authentication policies, continuous monitoring solutions, and education programs that emphasize cyber security best practices for all levels of personnel within the company structure.
