Information Security
Information Security (InfoSec) is the practice of protecting information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction. It encompasses strategies, policies, and technologies to ensure confidentiality, integrity, and availability of data, often referred to as the CIA triad. This field is critical in safeguarding digital assets against threats like cyberattacks, data breaches, and insider risks.
Developers should learn Information Security to build secure applications and systems, as security vulnerabilities can lead to data loss, financial damage, and reputational harm. It is essential for roles involving sensitive data, compliance with regulations (e.g., GDPR, HIPAA), and in industries like finance, healthcare, and e-commerce. Understanding InfoSec helps in implementing best practices such as encryption, authentication, and secure coding to mitigate risks.
