What are APIs and why are they a target for attacks?
Application Programming Interfaces (APIs) are software components that allow different applications to communicate with each other. Imagine them as digital interpreters, allowing two applications, which may speak different languages, to exchange information seamlessly. Web APIs, in particular, connect applications to other services or platforms, such as social networks, databases, and devices. They are the foundation for many interactions you perform online every day.
This widespread use makes APIs attractive targets for cybercriminals. APIs are vulnerable because they are often direct entry points to sensitive systems and data. Unlike traditional user interfaces, APIs are designed for machine-to-machine communication, which means that security measures are not as comprehensive.
A common type of threat is business logic attacks, which exploit the functions, data, or workflows of the API for malicious purposes. In addition, Broken Object-Level Authorization makes systems even more vulnerable, allowing unauthorized users to access resources they should not be able to access. Also, the lack of Rate Limiting can lead to Denial of Service (DoS) attacks or other types of abuse. Due to these vulnerabilities, cybercriminals can exploit APIs to break into systems, extract data, and disrupt business operations.
How can you identify real-time attacks on API servers in the cloud?
Detecting real-time attacks on cloud API servers is a dynamic challenge that requires a multi-layered approach. To effectively protect your API servers, you need to implement several advanced strategies and tools that provide real-time visibility and in-depth analysis of API traffic.
One of the cornerstones of real-time detection is the implementation of continuous monitoring and logging of API activity. By recording all interactions with your API, you can create a baseline of normal behavior. This makes it possible to identify anomalies that may indicate malicious activity. Pay particular attention to unusual traffic patterns, unsuccessful login attempts, and unexpected access to sensitive endpoints.
To enhance your monitoring capabilities, use API discovery and classification tools. These tools scan your cloud environment to identify all APIs, including those that may have been forgotten or not properly documented – often referred to as "shadow APIs." Understanding your complete API inventory is essential for effective security.
Another significant advantage is the use of anomaly detection powered by machine learning. These systems learn normal API behavior patterns and can quickly identify unusual deviations. For example, if a user starts accessing data or functions that they usually do not access, the machine learning system can flag this as suspicious activity. Machine learning can also identify more complex patterns that may escape traditional monitoring methods.
Integrating threat intelligence feeds is also essential. By feeding information about emerging threats and attack patterns into your monitoring system, you can stay one step ahead and respond more effectively to potential threats. Threat intelligence can help identify malicious IP addresses, URLs, and attack methods that have been used in the past.
Focus on identifying common API vulnerabilities, such as broken object-level permissions and excessive request rates. These vulnerabilities are often exploited in API attacks, so identifying them in real time can significantly help mitigate risks.
There are several solutions available that can help you with this task. Solutions like Imperva API Security and Salt Security are designed to provide real-time threat protection and detection. These solutions offer features such as automatic API discovery, behavioral analysis, and automated threat prevention.

Remember, the key to real-time detection is a combination of advanced tools, continuous monitoring, and a deep understanding of your API patterns. By implementing these measures, you can effectively protect your API servers in the cloud from a wide range of threats.
How to respond in real time to attacks on API servers in the cloud?
After you have identified an attack on your API servers in the cloud, a quick and correct response is critical to minimize damage and prevent data loss. An effective response requires advance planning, appropriate tools, and a prepared team.
First of all, make sure you are using strong and secure authentication methods. Strong passwords are just the beginning; implement multi-factor authentication (MFA) to add an extra layer of protection. MFA requires users to provide at least two authentication factors, making it harder for attackers to gain access even if they have obtained a password.
Enforcing proper authorization and access control mechanisms is also important. Restrict access to resources only to authorized users, and implement the principle of least privilege – giving users only the access they need to perform their role. This not only reduces the risk of unauthorized access but also helps contain any potential breaches.
Implementing Rate Limiting and Throttling is essential to prevent Denial of Service (DoS) attacks and abuse. Limiting the rate of requests a user can make in a given time period can prevent an attacker from flooding your servers with a huge volume of requests, thereby taking them down.
Practice input validation to reject malicious content and prevent injection attacks. Always check the data your servers receive, and reject any content that is too large or contains unwanted data. This helps protect against attacks where attackers try to inject malicious code into your systems.
One of the most important steps is to develop and execute an incident response plan for API security incidents. This plan should detail the steps to take in the event of a breach, including who should be involved, how to contain the attack, and how to recover from it. Regular testing of the plan is essential to ensure it is up-to-date and effective.
Make sure that error messages display minimal information to avoid exposing sensitive details to attackers. Detailed error messages can provide attackers with valuable insights into your system structure and potential vulnerabilities.
Finally, consider using API Gateways and API management solutions to enhance the security, control, and monitoring of your API traffic. API gateways can provide features such as authentication, authorization, rate limiting, and threat analysis, thereby significantly helping to reduce the risk of attacks.
