  1. Virtual Patching • “A security policy enforcement • layer which prevents the • exploitation of a known • vulnerability”

  2. Virtual Patching • Rationale for Usage • No Source Code Access • No Access to Developers • High Cost/Time to Fix • Benefit • Reduce Time-to-Fix • Reduce Attack Surface

  3. Strategic Remediation • Ownership is Builders • Focus on web application root causes of vulnerabilities and creation of controls in code • Ideas during design and initial coding phase of SDLC • This takes serious time, expertise and planning

  4. Tactical Remediation • Ownership is Defenders • Focus on web applications that are already in production and exposed to attacks • Examples include using a Web Application Firewall (WAF) such as ModSecurity • Aim to minimize the Time-to-Fix exposures

  5. OWASP ModSecurity Core Rule Set http://www.owasp.org/index.php/Category:OWASP_ModSecurity_Core_Rule_Set_Project
