Consider the following as the key measures (although by no means the only ones) that should be in place to secure against insider threats:
Implement access controls: Implementing strong access controls – such as role-based access and multi-factor authentication – can help to prevent unauthorised access to sensitive systems and information. Access controls should be reviewed and updated regularly to ensure their continued effectiveness.
Conduct background checks: Organisations should conduct background checks on all employees and contractors to verify their identities and flag any potential security risks. This can help to minimise the risk of insider threats by ensuring individuals who may be harbouring malicious intent are identified before they are hired.
Implement monitoring and detection: Implementing monitoring and detection systems, such as intrusion detection systems and data loss prevention technologies, can help organisations to detect and respond to suspicious activity. These systems should be configured to detect unusual access patterns, data transfers, and other potential indicators of an insider threat.
