  5. E-Commerce Security Drivers

  6. Business Is Changing Yesterday Today External Focus Internal Focus Suppliers, customers, and prospects all need some form of access Access is granted to employees only Distributed Assets Centralized Assets Applications and data are distributed across servers, locations, and business units Applications and data are centralized in fortified IT bunkers Generate Revenue Prevent Losses The goal of security is to protect against confidentiality breaches The goal of security is to enable eCommerce IT Control Business Control Security manager decides who gets access Business units want the authority to grant access Source: Forrester Research, Inc.

  8. The Internal Threat Is Real

  9. E-Commerce Issues Principle Business Drivers • Increase Revenue • Increase Profitability Principle Security Drivers • Greater Susceptibility to Attack • Greater Probability of Catastrophic Consequences • Much Greater “Loss to Incident” Ratio

  10. Our Strength Is Our Weakness • In Touch With Anyone With a Modem • Have an International Presence • Partners Can Now Collaborate • Leverage Web-based Supply Chain Technologies • Employees Can Work From Home, at Night, Over the Weekends, and on Holiday • Application Servers Can Support Entire Divisions

  11. Consequences • Exposure to Legal Liability

  12. DDoS Distributed Denial-of-Service Company A UNIX Firewall Web Server NT UNIX UNIX NT Company B Router University A Company C Company D

  13. Consequences • Exposure to legal liability • Decreased Stockholder Equity • 30 Seconds on CNN • Damaged Image

  14. Consequences • Exposure to Legal Liability • Decreased Stockholder Equity • 30 Seconds on CNN • Damaged Image • Decreased Employee Productivity • Loss of Intellectual Property & Assets • Inefficient Use of Resources

  15. Summary • E-Business is here to stay • Networks are exposed and under attack • There’s no more turning a “blind eye” • It’s a business issue and it should be treated in a business-like manner • Implement a security program not a security technology

  16. Developing a Security PolicyA Blueprint for Success

  17. Security Policy • Blue Print for Good Security Program • Standards Based - British Standard 7799 • Management Buy In • High Level to Technical • Business Driven Not Vendor Driven • Non-Static

  18. Enforced Security Policy • Minimize Exposure to Vulnerabilities • Prepare for Attacks on Our Systems • Manage Internal Staff Behavior • Manage External Access and Activity • Maintain Appropriate Security Configurations& Response Strategies • Exploit Built-in Security Features • Measure and Record Patterns and Trends for Future Security Planning

  19. The Anatomy of an Attack
