Secure API design requires multiple strategies to protect sensitive data and access.

SSRF is a vulnerability where an attacker tricks a server into making unintended requests.

Zero Trust Architecture ensures that no user or device is trusted by default.

CSRF tricks your browser into making requests without your consent.

API keys help identify clients and control their access to APIs securely.

Encryption at rest and in transit are essential for protecting data both stored and in motion.

Password hashing with unique salts ensures security by creating different hashes for identical passwords.

Session-based authentication uses cookies to remember users after login.

Hashing is one-way for verification, while encryption is two-way for confidentiality.

XSS is a vulnerability that lets attackers run scripts in users' browsers.

SQL injection is a security risk where attackers manipulate database queries via input fields.

Fail Fast means stopping quickly on errors, while Fail Safe ensures safety in failures.

KMS securely manages encryption keys to protect data from theft.

HTTPS is a secure version of HTTP that encrypts data for safety.

The TLS handshake establishes a secure connection for HTTPS, ensuring data safety.

Token expiration and refresh token rotation secure user sessions by limiting token lifespan and preventing unauthorized access.

mTLS allows microservices to verify each other's identities using certificates.

Authentication verifies who you are, while authorization determines what you can do.

Symmetric encryption uses one key, while asymmetric uses a pair of keys for security.

OAuth 2.0 lets apps access user data securely without passwords.

OpenID Connect allows apps to authenticate users and verify their identities securely.

Choosing the right boundaries for microservices is crucial for effective architecture.

The Bulkhead Pattern isolates resources to protect critical workloads from failures.

JWTs allow secure user authentication without needing session storage.

A single component's failure can take down your entire application, even with redundancy.

REST API design focuses on creating clean, efficient, and scalable web services.

Alerting helps notify the right people about production issues quickly.
