apsec 7 Golden Rules Data Leakage Prevention / DLP

  1. 1. The seven golden rules of Data Leakage Prevention Eng. Andreas Schuster Business Development Manager Applied Security GmbH (branch) Middle East
  2. 2. <ul><li>Applied Security GmbH </li></ul><ul><ul><li>Founded in 1998 </li></ul></ul><ul><ul><li>Main office in Stockstadt/Main, branch offices in London, Dubai and Grand Rapids, USA </li></ul></ul><ul><ul><li>Software development and consulting in IT security </li></ul></ul><ul><ul><li>Member of </li></ul></ul><ul><ul><li>www.apsec.de </li></ul></ul>About apsec
  3. 3. <ul><li>Applied Security US Incorporated </li></ul><ul><ul><li>Founded in September 2008 </li></ul></ul><ul><ul><li>US HQ Grand Rapids, MI </li></ul></ul><ul><ul><li>IT Security Software and Consulting </li></ul></ul><ul><ul><li>Member of ACG </li></ul></ul><ul><ul><li>www.apsec.us </li></ul></ul>About apsec
  4. 4. „ I already have a firewall...“ Why DLP?
  5. 5. No firewall could have prevented...
  6. 6. Examples of data loss <ul><li>May 2005 -- Time Warner lost 40 computer backup tapes containing sensitive data of about 600,000 current and former employees and service contractors while being shipped by Iron Mountain to an offsite storage center. </li></ul><ul><li>June 2006 – American International Group (AIG) lost personal data (names, adresses, SSNs, medical information) of 970,000 employees of various companies whose insurance information was submitted to AIG due to the burglary of a file server. </li></ul>
  7. 7. Examples of data loss <ul><li>November 2007 – In the U.K. Her Majesty's Revenues and Customs (HMRC) had to admit they'd lost computer disks containing personal information on almost half the country's population (25 million records), including nearly all families with children. If that's not bad enough, the databases included the worst kind of information to lose – consumer bank account numbers. </li></ul><ul><li>December 2007 –- The U.K. Ministry of Transport lost personal data of 3 million candidates for driver's licenses due to a vanished hard disk at a subcontractor's site in Iowa, USA. </li></ul>
  8. 8. Who wants to be next in line?
  9. 9. What should I do? Seven golden rules of Data Loss Prevention
  10. 10. What should I do? <ul><li>The stated examples have something in common: </li></ul><ul><ul><li>None of them has anything to do with an Internet-based attack or was caused by a security flaw in the network </li></ul></ul><ul><ul><li>Most commonly used protection measures such as Firewalls, IDS or Virus scanners could not have helped </li></ul></ul><ul><ul><li>The data breaches could have been prevented by a single measure – encryption! </li></ul></ul>
  11. 11. Rule No. 1: Accept that there is a risk!
  12. 12. Regel 1 <ul><li>If you think </li></ul><ul><li>„ This won‘t happen to me!“,... </li></ul>
  13. 13. Regel 1 <ul><li>...think again! </li></ul>
  14. 14. Rule No. 1 <ul><li>...because that‘s exactly what Time Warner, AIG, HMRC and all the other victims thought, too. Be smarter! </li></ul><ul><li>Hence: Accept that there is a risk! </li></ul><ul><li>But: Accept does not mean tolerate! </li></ul>
  15. 15. Rule No. 2: Provide Endpoint Security!
  16. 16. Rule 2 <ul><li>Identify: </li></ul><ul><ul><li>Which data are sensitive? </li></ul></ul><ul><ul><li>Who is allowed to work with sensitive data? </li></ul></ul><ul><li>Protect sensitive data on their point of origin: the user‘s workplace! (Endpoint Security) </li></ul>
  17. 17. Rule No 2: practical hints <ul><li>File encryption with access for workgroups </li></ul><ul><li>Restrict the use of mobile storage media </li></ul><ul><li>Encrypt confidential e-mail attachments automatically </li></ul><ul><li>Log all access to sensitive files </li></ul>
  18. 18. Rule Nr. 3: Take security into your own hands!
  19. 19. Rule No. 3: practical hints <ul><li>Demand central policy management! </li></ul><ul><li>Separate powers between system administrator and security officer </li></ul><ul><li>Grant access rights according to the „Need-to-know principle“ </li></ul><ul><li>Realize a four-eyes-principle </li></ul>
  20. 20. Rule No. 4: Make security easy!
  21. 21. Rule No.4: the human factor <ul><li>According to many surveys, human error is the No.1 reason for data breaches </li></ul><ul><li>There‘s nothing less secure than a misconfigured security solution </li></ul>
  22. 22. Rule No. 4: practical hints <ul><li>Invisible encryption in the background </li></ul><ul><li>Choose a rule-based and centrally managed solution </li></ul><ul><li>Care for an easy administration in order to reduce the chance of misconfiguration </li></ul><ul><li>Reduce complexity: don‘t choose the product with the longest feature list, but the one offering the functions you really need </li></ul>
  23. 23. Rule No. 5: Emergency precautions
  24. 24. Rule No. 5 <ul><li>Encryption is silver, but decryption is gold! </li></ul><ul><li>Ask: what to do if... </li></ul><ul><ul><li>Passwords are forgotten? </li></ul></ul><ul><ul><li>User keys are lost? </li></ul></ul><ul><ul><li>Configuration data are destroyed? </li></ul></ul><ul><li>Recovery mechanisms ensure the availability of your data! Ask your vendor about the mechanisms his solution offers! </li></ul>
  25. 25. Rule No. 6: The Pareto principle
  26. 26. Rule No. 6: The Pareto principle <ul><li>A typical dialogue: </li></ul><ul><ul><li>Customer: „I want 100% security!“ </li></ul></ul><ul><ul><li>Consultant: „There is no 100% security!“ </li></ul></ul><ul><ul><li>Customer: „In this case I want nothing at all!“ </li></ul></ul>
  27. 27. Rule No. 6: practical hints <ul><li>Prioritize your requirements! </li></ul><ul><ul><li>What is a „must“? </li></ul></ul><ul><ul><li>What is only „nice to have“? </li></ul></ul><ul><ul><li>What might even be counterproductive? </li></ul></ul><ul><li>Remember: 80% is much better than nothing! </li></ul><ul><li>The remaining risk must be tolerable! </li></ul>
  28. 28. Rule No. 7: Security costs money – but it is worth it!
  29. 29. Rule No. 7: Value for money <ul><li>A professional solution does not come as freeware from the Internet! </li></ul><ul><li>Data Leakage Prevention is a complex task – better ask a specialist! </li></ul><ul><li>Specialists earn their money with this – otherwise they wouldn‘t be specialists! </li></ul>
