Cybersecurity
Cybersecurity is the practice of protecting computer systems, networks, programs, and data from digital attacks, damage, or unauthorized access. It encompasses a broad range of technologies, processes, and practices designed to safeguard information technology assets and ensure confidentiality, integrity, and availability. This field addresses threats such as malware, ransomware, phishing, and data breaches through defensive and proactive measures.
Developers should learn cybersecurity to build secure applications, protect user data, and comply with regulations like GDPR or HIPAA. It's essential for roles involving sensitive data handling, cloud infrastructure, or internet-facing services to prevent costly breaches and maintain trust. Understanding security principles helps in implementing secure coding practices, threat modeling, and incident response across the software development lifecycle.
