Ongoing monitoring for emerging threats is equally important. Cybersecurity is an ever-changing landscape, with new threats emerging regularly. Organizations must stay vigilant by employing intrusion detection systems (IDS) or security operation centers (SOC) that can identify suspicious activities and respond swiftly before any damage occurs.

It is crucial not to place undue reliance on cryptography alone when it comes to network security. While encryption provides an essential layer of protection, it should be complemented by regular software updates, employee training programs, and proactive threat monitoring. By adopting a comprehensive approach that addresses all aspects of cybersecurity, organizations can minimize the risk of falling victim to cyber attacks and ensure the safety of their sensitive information.
