Top 6 API Security Risks That Go Unnoticed


With rising API security risks, organizations are facing new vulnerabilities every day, making it more important to inspect all APIs for potential security threats regularly.

As API security threats are more dangerous for the system than any other security breaches, organizations must be cautious and review everything closely before launching it into the markets. If businesses fail to do so, they are putting the business and consumers/ users at risk. Below down are some API security vulnerabilities that businesses overlooked-

No API Visibility & Monitoring

The use of APIs and devices increases along with the expanded use of cloud-based networks by businesses. This growth decreases the visibility of what APIs businesses expose internally or externally. The cyber-attacks on unknown APIs, API parameters, and business logic become more prevalent because of shadow, hidden or deprecated APIs which fall out of the business security team’s visibility. To avoid risks, the API visibility must include centralized visibility with the inventory of all APIs.

API Incompetence

The API security risks lie due to mistakes that businesses make. For instance, when businesses do not pay attention to API calls. It is important to avoid passing duplicate or repeated requests to the API. When two deployed APIs try to use the same URL, it can cause repetitive and redundant API usage problems as the endpoints on both APIs are serving on the same URL. To avoid API security risks, businesses must check each API for individual URLs with optimization.

Service Availability Threats

By sending service calls with incorrect requests and blocking legitimate traffic targeted DDoS (Distributed denial of service) API attacks can overburden the CPU cycles and processing power of the API server due to malware. The company servers where the APIs are running, as well as each API endpoint, are both targets of DDoS risks. Rate limitation gives organizations the assurance they need to keep the application functioning properly, but a solid response strategy includes multi-layer security solutions. Precise and thoroughly regulated API security continuously monitors the traffic on the API and immediately denies invalid requests before they reach the server.

API Utilization

Businesses in the B2B industry need to expose their internal API utilization numbers to third-party vendors. This process can be a great method to facilitate the partnership and permit others to access the business data and services, influencing API security risks in the business. It is important for businesses to be attentive to the API accessibility by others and the level of access they need. It is possible that businesses do not want to open their API too broadly and create security risks.

Businesses are required to monitor API calls closely for all the processes when they are shared between partners or customers. Following this process will ensure that every user is using API as intended and are not overloading the system.

API Injection

When malicious code is coded into an API due to negligence or carelessness, it can create huge security concerns, since APIs are highly susceptible to these. It is crucial for organizations to be aware of these cyber threats because the API security risks loophole poses serious problems for users, including identity theft and data breaches.

Adding input validation and avoiding the execution of special characters on the server side prevents businesses from API injection attacks.

IoT Devices Attacks

Businesses face trouble with their IoT devices since the effectiveness of IoT depends on the level of API security management; if that is not working, this amounts to API security risks, because, cybercriminals can find new ways to exploit vulnerabilities with advanced tools. The probability of increased API security risks becomes more prevalent even with APIs’ powerful extensibility as hackers get access to the sensitive data on business IoT devices. Therefore, API must be more secure in order to avoid any cyber threats and challenges IoT devices face.

Depending on the industry API can cause severe problems for the organization. Organizations can even face massive legal and compliance challenges for using insecure APIs. Therefore, the above-mentioned API security risks must be mitigated by increased awareness of the potential API vulnerabilities that cybercriminals have.
