DevSecOps Checks Required in Runtime API Gateways Logged in Data Lakes
Over the past ten years, there has been a significant change in the application development and operations landscape. The convergence of development, security, and operations—often referred to as DevSecOps—has emerged as a crucial tactic as businesses aim for speed and efficiency in order to produce high-quality software. The use of APIs, particularly in microservices and runtime API gateways, is a crucial element of contemporary software systems. These gateways are essential for controlling and safeguarding API traffic. The information that passes through these gateways is frequently recorded in data lakes, where it may be examined and used to gain knowledge. But there are also greater security threats associated with this increased complexity.
This article will discuss the significance of secure logging procedures in data lakes as well as the fundamental DevSecOps checks that ought to be applied in runtime API gateways. This talk will show how these checks can improve an organization’s security posture and guarantee compliance while preserving the speed and flexibility required by contemporary software development.
Understanding APIs and Runtime API Gateways
Modern software architectures rely heavily on APIs (Application Programming Interfaces), which facilitate communication between various software systems. APIs have become even more important with the rise of microservices architecture since they enable dynamic interaction between modular services. But growing dependence on APIs also leaves companies vulnerable to security flaws like hacked authentication tokens and injection attacks.
The intermediary layer between clients and microservices is a runtime API gateway. It offers a number of crucial features:
The Importance of Logging in Data Lakes
Organizations can store both organized and unstructured data at scale via data lakes, which are centralized repositories. Request and response logging is essential for APIs for a number of reasons:
-
Audit Trails
: Detailed API logs provide an audit trail necessary for compliance with regulations like GDPR, HIPAA, and PCI-DSS. -
Threat Detection
: Analyzing logs can reveal patterns that indicate malicious activity, such as repeated failed authentication attempts or unusual spikes in traffic. -
Performance Monitoring
: Logs contain performance metrics that are critical for understanding how APIs are performing and identifying bottlenecks. -
Debugging
: In the event of a failure, logs can be invaluable for diagnosing issues and implementing corrective actions.
DevSecOps Principles in API Gateways
One essential component of DevSecOps is putting security controls in place at every stage of the API lifecycle. By using an integrated approach, security checks are incorporated into the development, deployment, and runtime phases. The following crucial DevSecOps tests are necessary for runtime API gateways that are connected to data lakes:
The design stage should be where security starts. This includes:
-
Threat Modeling
: Identify potential threats to your API and create a model that helps prioritize security efforts. Consider the OWASP API Top Ten as a guide for common vulnerabilities. -
Secure Protocols
: Use secure protocols like HTTPS to encrypt data in transit and prevent man-in-the-middle attacks. -
Input Validation
: Ensure that all incoming data is validated against a strict schema to prevent attacks like injection.
-
OAuth and OpenID Connect
: Use industry-standard protocols for authentication and authorization to ensure that access to APIs is controlled. -
Token Management
: Properly configure token lifetimes and scopes to minimize the risk posed by compromised tokens. -
Role-Based Access Control (RBAC)
: Implement RBAC to ensure users can only access data necessary for their role.
-
Comprehensive Logging
: All API requests and responses should be logged, including metadata such as IP addresses, timestamps, and user identifiers. -
Structured Logs
: Use structured logging formats (like JSON) to make it easier to parse and analyze logs later in data lakes. -
Log Retention Policies
: Establish clear log retention policies to comply with data storage regulations.
-
At Rest and In Transit
: Encrypt sensitive data both at rest (in storage) and in transit (during transmission) using strong algorithms. -
Key Management
: Implement proper key management practices to safeguard encryption keys. This can involve using hardware security modules (HSMs) or cloud-based key management services.
-
API Gateway Security
: Ensure your API gateway includes security features like rate-limiting, IP whitelisting, and content filtering to protect against known attacks. -
Web Application Firewalls (WAF)
: Deploy WAF to monitor and protect APIs from malicious traffic.
-
Automated Scanning
: Regularly conduct automated scans for vulnerabilities in your APIs using tools that integrate into the CI/CD pipeline. -
Manual Testing
: Complement automated checks with manual penetration testing to uncover hidden vulnerabilities.
-
Preparation
: Develop and maintain an incident response plan specifically for API incidents. This should include clear communication channels and roles. -
Monitoring for Anomalies
: Use AI and machine learning-based tools to detect unusual patterns in API traffic that could indicate an ongoing attack.
-
Verify that the APIs abide with pertinent industry standards and laws, including PCI DSS, GDPR, and HIPAA. This could consist of:
-
Make sure users may request their data and understand how it’s used in order to comply with GDPR.
-
HIPAA Compliance: Make sure PHI (Protected Health Information) is sufficiently safeguarded for healthcare APIs.

Integrating Logging with Data Lakes
The power of runtime API gateway logs is increased when they are integrated with data lakes. Here’s one way to successfully include this data:
Gather logs from several API gateways and combine them into your data lake using a centralized logging system (such as Splunk, Azure Log Analytics, or ELK Stack). Data visualization and analysis are facilitated by this centralization.
Establish a transparent log structure with fields like:
- API endpoint
- HTTP method (GET, POST, etc.)
- Request and response status
- Timestamps
- User identifiers
- IP addresses
Discoverability for analytics is improved by documenting log schemas using data catalogs.
Use real-time analytics to identify irregularities in incoming logs as they occur. Teams can be informed of security incidents before they become more serious by using this proactive strategy.
Use historical log data for compliance checks and trend research. Over time, this can assist organizations in strengthening their API security posture by allowing them to learn from previous occurrences.
Conclusion
In conclusion, it is critical to ensure the security of APIs and microservices through strong DevSecOps procedures as enterprises quickly adopt them. Although runtime API gateways are essential for controlling and protecting API traffic, they also add complexity that may reveal weaknesses within an organization.
Organizations can develop a strong security strategy by putting in place the required DevSecOps checks, such as safe API design, runtime protection, and combining thorough logging procedures with data lakes. This improves the organization’s capacity to respond to attacks and uphold regulatory compliance in addition to safeguarding sensitive data.
Organizations must stay proactive, always enhancing and modifying their DevSecOps strategies as the threat landscape changes. By doing this, they can protect their networks and data while utilizing their APIs to their fullest potential.
