Conduct Red and Blue Team Training Exercises
SecOps team members can improve their security skills by participating in red and blue team exercises. The red team attacks the system using social engineering, port scanning, and vulnerability scans. In contrast, the blue team protects the system using vulnerability detection, security policy and tool evaluation, and analytics. The two teams train against each other and provide reports to help strengthen their overall SecOps capabilities.
Divide Processes Into Manual and Automated Workflows
Automation is essential for SecOps in large, fast-paced environments, allowing teams to monitor systems, detect anomalies, and identify vulnerabilities faster. Some security threats are possible to address automatically. However, some processes require manual involvement—for instance, complex incident response procedures and the creation of playbooks.
An effective SecOps strategy requires identifying which processes are suited to automation and what must remain manual. Striking a balance between manual and automated processes helps improve the SecOps team’s ability to implement a fast, thorough response.
Implement SecOps Throughout the Delivery Pipeline
SecOps teams must implement their processes to prevent and mitigate threats at every stage of the software delivery pipeline. Traditionally, security teams focus on the production environment, waiting until the end of the development pipeline to start testing and scanning. SecOps pushes these processes to the beginning of the pipeline—for example, by performing vulnerability immediately when writing code. Throughout and after deployment, teams should perform various security checks and monitoring.
A SecOps team typically receives constant barrages of alerts that become increasingly difficult to manage. Prioritizing and filtering the most important alerts helps reduce the noise and allows the team to focus on urgent and high-risk events. Prioritization is the key to optimizing response effectiveness and managing the SecOps team’s resources.
The SOC leadership can use various approaches to prioritize alerts, including data-driven (i.e., DLP), threat-driven, and asset-driven tools and strategies.
