As businesses increasingly rely on APIs to drive innovation and enhance customer experiences, the need for robust API security measures has never been greater . APIs often handle sensitive data, making them prime targets for attackers . Securitribe, a leading cybersecurity firm and Australia’s first partner of 42crunch, a prominent API security platform, is dedicated to establishing itself as a thought leader in the API security and DevSecOps space. This document delves into the critical aspects of API security, DevSecOps practices, and the broader ecosystem, providing valuable insights for organizations seeking to strengthen their API security posture.

Why API Security is Critical in 2025

The API security landscape is constantly evolving, with new threats and vulnerabilities emerging as technology advances. Recent studies have shown a concerning trend of API-related security incidents, with 57% of organizations experiencing an API-related data breach in the last two years . These incidents can have a significant financial impact, with remediation costs often exceeding $100,000 . Worryingly, only 21% of organizations report a high ability to detect attacks at the API layer, highlighting a critical gap in security posture.

One of the key challenges in API security is the difficulty in detecting attacks. Traditional security tools often focus on network-level threats and may not be equipped to identify vulnerabilities specific to APIs . This “blind spot” in API attack detection leaves organizations vulnerable to sophisticated attacks that can exploit API weaknesses to gain unauthorized access to sensitive data or disrupt critical services.

OWASP API Top 10

The OWASP API Security Top 10 provides a comprehensive list of the most critical API security risks that organizations need to be aware of and mitigate . These vulnerabilities include:

Broken Object Level Authorization: Failing to properly enforce access control checks, allowing attackers to access or modify data belonging to other users.
Broken Authentication: Weak or flawed authentication mechanisms that allow attackers to impersonate legitimate users and gain unauthorized access to API resources.
Broken Object Property Level Authorization: Failing to properly validate access permissions for individual properties within objects, potentially leading to data leakage or unauthorized modifications.
Unrestricted Resource Consumption: Not implementing rate limiting or resource throttling mechanisms, making APIs vulnerable to denial-of-service attacks or excessive resource consumption.
Broken Function Level Authorization: Failing to enforce proper access controls for specific functions or endpoints, allowing attackers to execute unauthorized actions.
Unrestricted Access to Sensitive Business Flows: Exposing sensitive business flows without adequate protection, allowing attackers to manipulate critical processes or gain unauthorized access to sensitive data.
Server-Side Request Forgery (SSRF): Fetching a remote resource without validating the user-supplied URL, potentially allowing attackers to access internal systems or sensitive data.
Security Misconfiguration: Inadequate configuration of API settings, such as leaving default settings unchanged or exposing sensitive information through error messages.
Improper Assets Management: Insufficient management of API environments and segregation, leading to vulnerabilities in under-secured endpoints or outdated API versions.
Insufficient Logging & Monitoring: Inadequate logging and monitoring practices that hinder the detection and response to API security incidents.

Why APIs are a Prime Target

APIs have become a primary target for malicious actors for several reasons :

Unsuitable Security Mechanisms: Traditional security mechanisms like API gateways and WAFs are often insufficient for protecting APIs. These tools may not be able to effectively detect and prevent attacks that exploit API-specific vulnerabilities.
Direct Access to Critical Business Functions and Sensitive Data: APIs often provide direct access to critical business functions and sensitive data, making them attractive targets for attackers.
