Background for this topic.
Application Programming Interfaces (APIs) are sets of rules that allow software applications to communicate and exchange data, often enabling functionality across different systems or services. APIs define how requests and responses are structured, making it possible for programs to interact without direct user involvement. In cybersecurity, APIs are commonly exposed over networks as endpoints that handle sensitive operations like data retrieval, user authentication, or transaction processing.
APIs increase the attack surface by exposing endpoints that attackers can target with unauthorized access attempts, injection attacks, or denial-of-service. Common risks include weak or missing authentication, insufficient input validation, and improper rate limiting. Effective API security requires strong authentication protocols (e.g., OAuth), strict input validation to prevent injection, rate limiting to mitigate abuse, and comprehensive logging to detect anomalies. Protecting APIs is critical to prevent data leaks, privilege escalation, and service disruption in interconnected environments.
Google says an API management issue is behind Thursday's massive Google Cloud outage, which disrupted or brought down its services and many other online platforms. [...]
AI is changing everything — from how we code, to how we sell, to how we secure. But while most conversations focus on what AI can do, this one focuses on what AI can break — if you’re not paying attention
ChatGPT o3, which has been available via API, is now 80% cheaper for developers, and there's no visible impact on performance. [...]
Modern enterprise networks are highly complex environments that rely on hundreds of apps and infrastructure services. These systems need to interact securely and efficiently without constant human oversight, which is where non-human identities (NHIs) come in. NHIs — including application secrets, API keys, service accounts, and OAuth tokens — have exploded in recent years, thanks to an
