Computer Science and Engineering (CSE) is fundamental to the field of Cybersecurity, providing the underlying technologies and methodologies used to protect digital systems, networks, and data from unauthorized access, attacks, and damage. CSE equips professionals with the skills to design secure software, develop cryptographic protocols, and implement intrusion detection systems. With the increasing sophistication of cyber threats, such as malware, ransomware, and phishing attacks, CSE focuses on creating advanced defense mechanisms, including firewalls, encryption techniques, and secure coding practices, to mitigate vulnerabilities. Additionally, CSE supports the development of secure infrastructure through network security protocols, risk assessment tools, and incident response strategies. As cyber threats continue to evolve, the role of CSE in developing new techniques for threat detection, prevention, and recovery becomes even more critical in safeguarding sensitive information and maintaining the integrity of digital ecosystems.
