API Security and Unified API Protection FAQ

API Security is a crucial aspect of ensuring the protection and integrity of application programming interfaces (APIs) by implementing essential measures to counter risks and vulnerabilities that could lead to data breaches, fraudulent activities, and operational disruptions. To achieve optimal API security, it is vital to adhere to three core principles: API discovery, risk and compliance analysis, and threat remediation and mitigation. Key concepts in API security include secure API management, data security, and safeguarding sensitive information.
  1. The initial step in API Security involves the identification and cataloging of all APIs, including managed, unmanaged, shadow, zombie, third-party, internal, and external APIs. This process ensures proper access management, compliance with OWASP API Security guidelines, and overall network and application security.
  2. The second phase, API Security risk analysis emphasizes identifying coding errors that may expose vulnerabilities (API risks) and targeted attacks that could exploit these vulnerabilities or attempt to manipulate business logic (API threats). Detecting attacks and threats necessitates more comprehensive analysis, which may involve human intervention, digital tools, or a combination of both.
  3. The final aspect of API Security involves the detection and remediation of risks and the mitigation of threats identified during the detection phase. Risk remediation involves notifying the development team of the detected risks and confirming the implemented fixes through continuous analysis, testing, and cybersecurity measures. Native threat mitigation necessitates real-time responses without relying solely on signaling a web application firewall (WAF) or employing other tools. Implementing authentication protocols such as OAuth, securing cloud-based applications, and maintaining rigorous application security standards are essential to preventing unauthorized access and ensuring the protection of sensitive data.
API Security is vital for safeguarding APIs from potential threats and vulnerabilities, ensuring data security and the protection of sensitive information. By following the three fundamental principles of API discovery, risk and compliance analysis, and risk and threat remediation and mitigation, organizations can create a secure environment for their APIs, applications, and networks.
Unified API Protection is the practice of protecting your application programming interfaces (API) from threats and vulnerability exploits throughout the API protection lifecycle: API discovery, inventory, risk analysis and compliance, security testing, threat detection, and threat mitigation. Unified API Protection goes beyond the using point products to address individual phases, such as compliance or testing, along with legacy security technologies to protect your APIs.

Unified API Protection begins with the discovery and inventory of all public-facing APIs along with their associated resources. Then using that inventory to continually track all APIs – managed, unmanaged, shadow, zombie, third-party, internal and external.

Unified API Protection continues with compliance, accomplished by analyzing APIs to enforce OpenAPI specification conformance, and adherence to government regulations like PCI. Compliance also entails continuous risk assessment to find coding errors quickly. Unified API Protection solutions include threat detection to find vulnerability exploits and business logic attacks.

Finally, Unified API Protection solutions also include threat mitigation and API security testing. Threat mitigation means using alerts, real-time blocking and even deception for attack response, without the need to signal third-party tools. API security testing uses API specific test cases to help security and development teams uncover and remediate errors before they become security incidents.
The types of API security solutions available can include API gateways, web application firewalls (WAF), API specific security tools and Unified API Protection. It’s important to understand how each of these tools addresses an organizations’ API security requirements, which typically entail API discovery, threat and risk detection followed by mitigation and remediation.

The first type of API security are API gateways, which are designed to aggregate and manage APIs. API gateways include basic security functions such as rate limiting and IP block lists. API gateways are unable to proactively discover APIs and do not perform threat detection, risk analysis, remediation or mitigation.

The next type of API security is a WAF, which is web focused and do not perform automated API discovery, or uncover coding errors. WAFs use signatures to detect known vulnerabilities found in the OWASP Web Application Top 10 Threats list.

The third type of API security is an API specific toolset which focuses on helping development produce APIs with fewer errors. These tools fall short of addressing the complete set of API security requirements defined above.

The most complete type of API security is a Unified API Protection solution, complete with API discovery, threat and risk detection followed by mitigation and remediation. Unified API Protection goes beyond using point products to address individual phases, such as compliance or testing, along with legacy security technologies to protect your APIs.
Common API security risks are those defined by the Open Web Application Security Project (OWASP) API Security Top 10, business logic attacks, known informally as OWASP API 10+ and coding errors that are exploited by attackers.

Common API security defined by the OWASP API Security top 10 list include a threat definition and how to address them. Examples include sensitive data exposure, authentication errors, resource and rate limiting. A top 10 list means there are many others, so it’s important to use OWASP API Top 10 as a starting point.

A common API security risk often overlooked is business logic abuse, or attacks on perfectly coded APIs. Known informally as OWASP API 10+, this category encompasses the different ways perfectly coded APIs are attacked using techniques outside of the OWASP API Security Top 10. Examples include large scale shopping bots, enumeration attacks and account takeovers – all against properly coded APIs.

The last group of common API security risks are unknown vulnerability exploits caused by API coding errors. . This group of API security risks places significant emphasis on API testing as well as continuous threat detection and mitigation to protect the improperly coded API while a fix is rolled out.
Application Programming Interfaces (APIs) have become an integral part of modern software development, enabling seamless integration and communication between various applications, services, and platforms. As the reliance on APIs grows, so does the need for robust API security measures to protect sensitive data and ensure the overall stability of digital ecosystems. This comprehensive guide will provide an in-depth understanding of API security, its importance, best practices, and strategies to help you secure your APIs and safeguard your organization from potential risks.

By comprehending the key components of API security, implementing best practices, and utilizing the appropriate tools and technologies, organizations can effectively mitigate risks, safeguard sensitive data, and maintain the integrity of their digital ecosystems. This all-encompassing guide to API security serves as an invaluable resource for both technical and non-technical stakeholders, assisting them in the development and maintenance of secure APIs and, ultimately, contributing to the overall security posture of their organization.
API security and API protection are two terms often used interchangeably in cybersecurity. However, these terms refer to distinct yet overlapping concepts. You can secure your APIs all day along but clever hackers will always find a way to launch attacks on perfectly coded APIs. This is why organizations need to protect APIs in addition to securing them.

API security focuses on the principles and methods used to secure an Application Programming Interface (API) from malicious exploits, unauthorized access, and other potential cyber threats. It involves a broad range of practices such as authentication, authorization, encryption, and input validation to safeguard the API. The goal is to ensure that only authorized entities can interact with the API and that they can only perform actions that align with their granted permissions. API security is about managing the risks associated with exposing APIs, which are the critical interfaces that connect systems, services, and data.

On the other hand, API protection encompasses API security but also extends beyond it. While API security is more focused on preventing unauthorized access and malicious attacks, API protection involves a more holistic view of maintaining the integrity, availability, and performance of APIs. In addition to API security, it includes two other key components:
  1. Discovery – Detecting all APIs using both inside-out and outside-in methods to know exactly where we need to apply API security tools.
  2. Threat Protection – Once threats are detected, stop them in their tracks natively without relying on a third-party solution such as a WAF. It includes measures to protect against threats such as Denial of Service (DoS) attacks, rate limiting to manage the number of requests an API can handle, and continuous monitoring to detect any unusual activities or anomalies.

Furthermore, API protection includes managing the API lifecycle, versioning, and deprecation to ensure that the APIs continue to serve their intended purpose without disruption. It also deals with the quality of the APIs, ensuring that they are robust, reliable, and efficient. API Protection takes into account not just security but also the overall health and performance of APIs.

In summary, while API security is an integral component of Unified API Protection, the latter takes a more comprehensive approach. Unified API Protection considers all aspects that could affect the usability, reliability, and performance of APIs. It is essential for organizations to focus on both API security and API protection when developing and managing APIs to ensure they deliver their intended functionality securely, reliably, and efficiently.

This is why, for a business to thrive in today’s interconnected digital world, a holistic approach that encapsulates both API security and API protection is critical.
