Deploy One or More Centralized Log File Monitors and Configure Logging Devices throughout the Organization to Send Data Back to the Centralized Log Monitor4. Determine the Impact of Events Both Before and After they Occur5. Develop a Threshold for How Many Times an Event Can Occur Before You Take ActionB. Continuous Monitoring1. Develop Strategies for Detecting Breaches as Soon as Possible, Emphasizing Continuous Surveillance of Systems through Network Monitoring2. Ensure That Appropriate Access to the Physical Environment Is Monitored, Most Likely through Electronic Monitoring or Alarm Systems3. Monitor Employee Behavior in Terms of Both Physical and Electronic Access to Detect Unauthorized Access 4. Develop a System for Ensuring That Software Is Free of Malicious Code through Software Code Inspection and Vulnerability Assessments5. Monitor Mobile Code Applications (e.g., Java Applets) for Malicious Activity by Authenticating the Codes’ Origins, Verifying their Integrity, and Limiting the Actions they Can Perform6. Evaluate a Provider’ s Internal and External Controls’ Adequacy and Ensure they Develop and Adhere to Appropriate Policies, Procedures, and Standards; Consider the Results of Internal and External Audits7. Monitor Employee Activity for Security Purposes and Assess When Unauthorized Access Occurs8. Use Vulnerability Scanning Tools to Find Your Organization’ s WeaknessesC. Detection Processes1. Establish a Clear Delineation between Network and Security Detection, with the Networking Group and the Security Group Having Distinct and Different Responsibilities2. Create a Formal Detection Oversight and Control Management Function; Define Leadership for a Security Review, Operational Roles, and a Formal Organizational Plan; Train Reviewers to Perform Their Duties Correctly and Implement the Review Process3. Test Detection Processes Either Manually or in an Automated Fashion in Conformance with the Organization’ s Risk Assessment4. Inform Relevant Personnel Who Must Use Data or Network Security Information about What Is Happening and Otherwise Facilitate Organizational Communication5. Document the Process for Event Detection to Improve the Organization’ s Detection SystemsSummaryChapter QuizEssential Reading for Tools and Techniques for Detecting a Cyberattack
