What is API Abuse ❓ Prevention measures.

APIs are paramount for constructing a steadfast and constant communication bridge that empowers devices to pass-on desired information seamlessly. Hackers adopt many ways to exploit the APIs and corrupt the targeted device. This API exploitation is a potential threat to API security and needs foremost attention while constructing utterly secured application development is the goal.

What is API abuse?

Consequences of API abuse

API abuse exists in many forms, a few examples are:

  • Injection Attacks

This method requires adding a piece of malicious code script in an API. The attack happened only on API featuring vulnerabilities. Presently, injection attackers are the most notorious abuse for web apps as well as APIs.

Currently, SQLi and XSS are the most common types of this attack in use. The code insertion can happen in the API code or in the API message.

  • DDoS Attacks

It is a key type of API abuse wherein the threat actor prevents legitimate access to a particular device or system. Hackers make this happen by encumbering APIs with huge traffic volumes. The traffic is sent with the help of a bot and asymmetrical processes.

This type of attack consumes system resources at a huge scale and makes them inaccessible to intended users. The Distributed Denial of Service (DDoS) attack can occur at a slow pace, wherein negligible bandwidth is consumed, or at a fast speed as well. Either way, this type of API abuse tarnishes the reputation of the applications and systems as end-users fail to use them.

  • Data Exposure

APIs are used mainly to let 2 or more endpoints communication and share data whenever required. When API abuse happens, the information warehoused in the APIs is likely to be exposed to ill resources. RESTful APIs are more prone to this hander as they transfer data over HTTP protocol.

How to prevent API abuse?

  • Every API call coming from bots should be monitored and managed through and through. As most API abuse happens with the help of bots, API calls made from bots shouldn’t be entertained casually.
  • API authentication and authorization of the highest grade should be implemented.
  • The API login process must have the backing of 2FA and robust encryption.
  • The entire API path should be watched over carefully to spot any vulnerability in the infancy stage.
  • For effective fault tolerance, one must adopt the cluster API implementation process.

All sorts of APIs, public or private, SOAP or REST, and many more should have effective API security measures in place. Tools like Wallarm make this happen as it offers every necessary resource to keep API vulnerabilities at a minimum level and keep API abuse probabilities as low as possible.
