Data Security
Data security is the practice of protecting digital information from unauthorized access, corruption, or theft throughout its lifecycle. It encompasses a set of policies, tools, and techniques designed to ensure data confidentiality, integrity, and availability. This includes measures like encryption, access controls, and security protocols to safeguard data in storage, processing, and transmission.
Developers should learn data security to build applications that protect sensitive user information, comply with regulations like GDPR or HIPAA, and prevent costly data breaches. It is essential in industries such as finance, healthcare, and e-commerce, where handling personal or financial data requires robust security measures to maintain trust and avoid legal penalties.
