Vulnerability Remediation : Partnering directly with development teams to explain vulnerability root causes, provide secure coding examples, and guide them through the remediation process. Code Review : Conducting targeted security code reviews for critical applications, focusing on architectural security flaws and common specific vulnerabilities (e.g., deserialization issues, Spring/Struts security misconfigurations, injection flaws). Secure Coding Standards : Developing and promoting secure coding standards and best practices and associated frameworks. Documentation & Training : Creating high-quality documentation, training materials, and run hands-on workshops to elevate the security knowledge of engineering teams.
