This includes implementing strong access controls, maintaining rigorous monitoring of network traffic to detect unauthorized exfiltration, and ensuring comprehensive encryption for data both at rest and in transit. Additionally, maintaining a clear incident response plan and adhering to regional data protection standards are essential components of a modern cybersecurity posture.
