Cyber Security in Computer Science Engineering (CSE) focuses on the protection of computer systems, networks, and data from unauthorized access, attacks, or damage. It involves the study of various security measures to ensure the confidentiality, integrity, and availability of information. This field includes topics such as encryption, ethical hacking, network security, malware analysis, risk management, and the development of secure software.

Cyber security professionals work to identify potential vulnerabilities in systems, devise strategies to mitigate risks, and ensure that sensitive information is safeguarded from cyber threats such as hacking, phishing, ransomware, and data breaches. With the growing reliance on digital technology and the increasing frequency of cyberattacks, cyber security is a critical area of focus in modern computer science education and practice.
