Network Security
Network security is a set of practices, technologies, and policies designed to protect the integrity, confidentiality, and availability of computer networks and data from unauthorized access, misuse, or attacks. It involves implementing measures such as firewalls, intrusion detection systems, encryption, and access controls to secure network infrastructure and traffic. The goal is to prevent threats like malware, hacking, and data breaches while ensuring network resources remain functional and trustworthy.
Developers should learn network security to build and maintain secure applications and systems, especially in today's interconnected world where cyber threats are prevalent. It is essential for roles involving web development, cloud computing, or IoT, as it helps protect sensitive data, comply with regulations like GDPR or HIPAA, and prevent costly security incidents. Understanding network security enables developers to implement secure coding practices, configure network defenses, and collaborate effectively with security teams.
