API Security Fundamentals: How to Discover, Scan and Protect APIs

Understanding and securing APIs is essential for maintaining API security and mitigating the risks of account takeover attacks. Security professionals must learn how to prevent future attacks and effectively identify unknown endpoints, especially those that handle sensitive data.

Here are the fundamental steps to achieve this:

Discover APIs: Begin by conducting an inventory of all the APIs within your organization. This involves understanding which APIs are exposed, their endpoints, and the data they access. Regularly audit and update this inventory to keep track of changes and new APIs.

Scan APIs: Conduct regular security scans and assessments of your APIs to identify potential vulnerabilities and weaknesses. This includes testing for common API security issues like injection attacks, authentication flaws, and excessive data exposure. Use specialized API Protection tools and engage security researchers to evaluate your API infrastructure thoroughly.

Protect APIs: Implement a comprehensive API protection strategy that includes multiple layers of security controls. Start by applying access controls and proper authentication mechanisms such as multi-factor authentication and token-based authorization. Employ robust encryption and secure coding practices to safeguard sensitive data transmission. Use rate limiting, anomaly detection, and behavioral analysis to detect and prevent malicious activities like bot attacks and brute-force attempts.

Robust API Security Strategies

Robust API protection strategies are crucial in mitigating the risks associated with account takeover attacks and safeguarding customers and businesses. Implementing advanced security solutions, such as the Unified API Protection platform offered by Cequence Security, can provide comprehensive protection against various attack vectors.

A comprehensive API security strategy should include multiple layers of security controls. Access controls and proper authentication mechanisms like multi-factor authentication and token-based authorization are essential to verify the legitimacy of users and prevent unauthorized access. Robust encryption and secure coding practices ensure the secure transmission of sensitive data.

Rate limiting, anomaly detection, and behavioral analysis are effective techniques to detect and prevent malicious activities. Organizations can identify and block bot attacks and brute-force attempts by monitoring traffic patterns and user behavior.

Securing APIs: Effective Measures to Prevent Misuse and Exploitation:

Monitor and manage API calls coming from bots, and stop using obsolete and insecure authentication methods

Implement measures to prevent API access by sophisticated human-like bots

Use robust encryption to safeguard log-in processes

Deploy token-based rate limiting equipped with features to limit API access based on the number of IPs, sessions, and tokens

Comprehensively log all system requests and responses

Scan incoming requests for malicious intent Support clustered API implementation to handle fault tolerance

Track the usage and paths taken by API calls to find anomalies Leading analyst organizations recommend that enterprises should implement effective API security measures.

Login APIs Targeted by Account Takeover Attacks

According to recent research, login APIs have become a prime target for account takeover attacks. These attacks, where threat actors gain unauthorized access to user accounts, pose a significant threat to online services and their users. Attackers employ various methods to compromise login APIs, with stolen credentials being a common tactic.

One technique frequently used by attackers is credential stuffing, where stolen login credentials obtained from data breaches are systematically tested against multiple online services. This method takes advantage of the fact that users often reuse passwords across different accounts, making it easier for attackers to gain access.

Additionally, attackers employ rotating proxies to obfuscate their IP addresses, making tracking and blocking their activities more challenging. Attackers can bypass rate limiting and evade detection systems by continually changing their proxies.

Successful account takeover attacks can lead to severe consequences for users and organizations. Unauthorized fund transfers, in particular, pose a significant financial risk. Attackers may exploit compromised accounts to initiate fraudulent transactions, resulting in financial loss for the user and reputational damage for the targeted organization.

Clientless API Security Used to Prevent Account Takeover Attempts

Clientless API security is crucial in preventing account takeover attempts and safeguarding user accounts from unauthorized access. Unified API Protection (UAP) solution employs advanced machine learning-based analytics to detect account takeover attacks (ATOs) and other automated attacks.

Through clientless API security, organizations can secure their APIs without requiring any application or code modifications. This approach ensures that even legacy systems and third-party applications can benefit from robust security measures. By implementing clientless API security, organizations can effectively defend against ATOs and mitigate the risk of malicious actors gaining unauthorized access to user accounts.

UAP solution leverages machine learning algorithms to analyze API traffic patterns and identify suspicious activity indicative of ATO attempts and other automated attacks. This advanced ML-based analytics allows for real-time detection and response, enabling organizations to defend against threats proactively.

Predefined policies that can be customized based on specific security requirements to enhance security further. These policies allow organizations to tailor their defenses to address potential attack vectors. Organizations can choose from various response options in the event of malicious activity, including blocking the attacker, initiating multi-factor authentication, or applying rate-limiting measures.

Existing Security Controls May Not Protect APIs against ATO Attacks

Existing security controls may not be enough to protect APIs against Account Takeover (ATO) attacks. Traditional security measures such as web application firewalls (WAFs) and security information and event management (SIEM) systems have their limitations when it comes to identifying and preventing bot attacks on APIs.

APIs handle a high volume of machine-to-machine traffic, making it difficult for traditional security controls to distinguish between legitimate user requests and malicious bot activity accurately. Bots can bypass traditional security measures by mimicking legitimate user behavior, making it challenging to detect and mitigate their attacks.

Organizations need a comprehensive API security strategy to protect against ATO attacks on APIs effectively. This strategy should utilize advanced technologies such as artificial intelligence (AI) and machine learning (ML) engines to analyze API traffic patterns and identify suspicious activity. Behavior monitoring should also be implemented to detect anomalies and potential ATO attempts.

Final Thoughts

API security is of utmost importance in today’s digital economy, as APIs play a crucial role in enabling seamless integration and communication between different systems and applications. However, the increasing number of APIs also poses a significant challenge in terms of ensuring their security.
