- Compromised Insiders: Targets of social engineering frauds in which employees’ accounts are compromised by outsiders to steal organizational data.

Tip: To ensure maximum security is provided, embrace often security assessment, and vulnerabilities such as cracks should be detected through penetration testing.
- Regular internal reviews should be performed to assess degrees of conformance with security policies and to determine where possible lapses may have occurred.

Implement an infrastructure that does not trust any request whether internal or external and authorizes each request.
2. Behavioral Analytics:
Employ user behavioral analysis to identify aberrations from norms that could be expected, which is an indicator of the insider threat.
3. Data Loss Prevention (DLP):
Make use of DLP solutions for the detection and prevention of improper flow of data, call it leakage as well.
4. Segmentation:
Subdivide various networks and databases to contain the risk of insider threat.
5. Whistleblower Programs:
Measures that require the personnel to participate in whistle-blowing where they could report acts of fraud honestly.
