Application Security: The practice of safeguarding applications from threats and vulnerabilities to ensure the confidentiality, integrity, and availability of the data they handle. Application security focuses on securing the software itself through practices like secure coding, input validation, and security testing, including vulnerability scanning and penetration testing. Examples of application security measures include code reviews, secure development practices, and the implementation of security patches. While broader measures like firewalls and intrusion detection systems contribute to overall cybersecurity, application security centers specifically on protecting the application layer.
