![]() ![]() Although it does improve API performance for those accessing it. This purpose clearly isn’t security-related. These gateways can also be used for routing and traffic management - in other words, to load-balance incoming API requests to different endpoints.Typically, these apply some sort of GET-based rate limit that can be sensibly used to distinguish between humans and legitimate applications and those making illicit use of the API, such as attempting to use it to scrape or harvest user data. Rate-limiting designed to distinguish between normal API usage and that originating by unauthorized bots.More broadly, these can be used to implement firewall-type rules designed to block access from specific geolocations. These can work in conjunction with third-party lists of IPs associated with both established and emerging threat actors. ![]() Origin IP-based rules such as allowlists and blocklists.Core API gateway functionalities include: In a typical network architecture, API gateways are placed immediately before API endpoints - serving as access control points. API gateways work at the network level but, more specifically, they handle incoming traffic requests specifically seeking the API. What Does an API Gateway Do?ĪPI gateways are designed to handle authentication and authorization of requests to access an API. We’ll explain exactly what independent value each of these solutions brings, how they work together, and why defense-focused organizations should be deploying all three to better manage their security. Increasingly, all three of these components are considered essential components of the API-protection stack, working at different levels of the TCP/IP model in order to protect APIs from malicious targeting. In this blog post, we’re going to explain the differences between three different security tools that can protect various parts of a company’s online footprint: WAFs, API gateways, and API security platforms. API-targeting exploits can include everything from attacks that target websites (such as brute force methodologies intended to suppress API availability to legitimate users) to attempts to flood endpoints with queries to illicitly obtain user information and DDoS-style query-flooding. ![]()
