Here are some of the most common <strong data-start=\"2579\" data-end=\"2602\">API vulnerabilities<\/strong>:<\/p>\n<h3 data-start=\"2605\" data-end=\"2637\"><strong data-start=\"2609\" data-end=\"2637\">1. Broken Authentication<\/strong><\/h3>\n<p data-start=\"2638\" data-end=\"2773\">When APIs fail to properly authenticate users, attackers can hijack credentials or use brute-force methods to gain unauthorized access.<\/p>\n<h3 data-start=\"2775\" data-end=\"2804\"><strong data-start=\"2779\" data-end=\"2804\">2. Insecure Endpoints<\/strong><\/h3>\n<p data-start=\"2805\" data-end=\"2919\">Poorly configured or exposed API endpoints allow hackers to exploit functions directly, bypassing user interfaces.<\/p>\n<h3 data-start=\"2921\" data-end=\"2955\"><strong data-start=\"2925\" data-end=\"2955\">3. Excessive Data Exposure<\/strong><\/h3>\n<p data-start=\"2956\" data-end=\"3056\">Some APIs return more information than necessary, revealing confidential data to unauthorized users.<\/p>\n<h3 data-start=\"3058\" data-end=\"3086\"><strong data-start=\"3062\" data-end=\"3086\">4. Injection Attacks<\/strong><\/h3>\n<p data-start=\"3087\" data-end=\"3205\">Attackers inject malicious scripts or commands (like SQL or XML injections) into API requests to compromise databases.<\/p>\n<h3 data-start=\"3207\" data-end=\"3239\"><strong data-start=\"3211\" data-end=\"3239\">5.

Below are proven <strong data-start=\"3527\" data-end=\"3558\">API security best practices<\/strong>:<\/p>\n<h3 data-start=\"3561\" data-end=\"3615\"><strong data-start=\"3565\" data-end=\"3615\">1. Use Strong Authentication and Authorization<\/strong><\/h3>\n<p data-start=\"3616\" data-end=\"3758\">Adopt <strong data-start=\"3622\" data-end=\"3635\">OAuth 2.0<\/strong> and <strong data-start=\"3640\" data-end=\"3658\">OpenID Connect<\/strong> for secure user authentication. Implement <strong data-start=\"3701\" data-end=\"3737\">Role-Based Access Control (RBAC)<\/strong> to limit privileges.<\/p>\n<h3 data-start=\"3760\" data-end=\"3794\"><strong data-start=\"3764\" data-end=\"3794\">2. Enforce Data Encryption<\/strong><\/h3>\n<p data-start=\"3795\" data-end=\"3934\">Always use <strong data-start=\"3806\" data-end=\"3840\">TLS (Transport Layer Security)<\/strong> to encrypt data in transit. Encryption ensures that even intercepted data remains unreadable.<\/p>\n<h3 data-start=\"3936\" data-end=\"3985\"><strong data-start=\"3940\" data-end=\"3985\">3. Implement Rate Limiting and Throttling<\/strong><\/h3>\n<p data-start=\"3986\" data-end=\"4112\">Restrict how many requests a client can make per minute. This helps prevent <strong data-start=\"4062\" data-end=\"4089\">DoS (Denial of Service)<\/strong> attacks and API abuse.<\/p>\n<h3 data-start=\"4114\" data-end=\"4144\"><strong data-start=\"4118\" data-end=\"4144\">4. Validate Input Data<\/strong><\/h3>\n<p data-start=\"4145\" data-end=\"4257\">Always check that incoming data matches expected formats to prevent <strong data-start=\"4213\" data-end=\"4234\">injection attacks<\/strong> or malformed requests.<\/p>\n<h3 data-start=\"4259\" data-end=\"4289\"><strong data-start=\"4263\" data-end=\"4289\">5. Regularly Test APIs<\/strong><\/h3>\n<p data-start=\"4290\" data-end=\"4403\">Conduct <strong data-start=\"4298\" data-end=\"4321\">penetration testing<\/strong>, <strong data-start=\"4323\" data-end=\"4349\">vulnerability scanning<\/strong>, and follow <strong data-start=\"4362\" data-end=\"4391\">OWASP API Security Top 10<\/strong> guidelines.<\/p>\n<h3 data-start=\"4405\" data-end=\"4432\"><strong data-start=\"4409\" data-end=\"4432\">6.
