MISO L008 Disaster Recovery Plan

  1. 1. ManagementInformation Systemsin Organizations<br />DISASTER<br />RECOVERY PLAN<br />Prepared by: Jan Wong<br />
  2. 2. The Learning Outcomes<br />At the end of this session you should be able to:<br />the importance ofdisaster recovery in an organization<br />EXAMINE<br />the steps in risk management approach<br />DESCRIBE<br />backup systems and system recovery<br />DISCUSS<br />
  3. 3. Danger<br />Jeopardy<br />Threat<br />RISKS<br />Peril<br />Menace<br />Hazard<br />
  4. 4. Thinking about risk<br /><ul><li>Chance (probability) of something happening
  5. 5. Impact (cost) if it happens</li></ul>Is it possible to protect against every risk?<br />What is RISK?<br />“The chance of a negative outcome”<br />
  6. 6. A risk-management approachhelps <br />identify threats and <br />select cost-effective security measures.<br />Risk-management analysis can be enhanced by the use of DSS software packages. <br />Calculations can be used to compare the expected loss with the cost of preventing it. <br />A business continuity planoutlines the process in which businesses should recover from a major disaster<br />Risk ManagementApproach<br />“What is it all about?”<br />
  7. 7. What are the STEPS in RISK MGMT.?<br />
  8. 8. STEP 1:<br />Determine the value and importance of assets<br />Infrastructure: hardware, networks, security environment itself<br />Software environment<br />Staff<br />Cost of replacement<br />Cost of loss of use<br />Assessment of assets<br />
  9. 9. STEP 2:<br />List all potential threats<br />Review the current protection/controls system<br />Record weaknesses in the current protection system in view of all the potential threats<br />Vulnerability of assets<br />
  10. 10. STEP 3:<br />Assess the probability of damage<br />Specify the tangible and intangible losses that may result<br />Loss analysis<br />
  11. 11. STEP 4:<br />Provide a description of available controls that should be considered – general, application, network etc<br />Probability of successful defense<br />The cost<br />Protection analysis<br />
  12. 12. STEP 5:<br />Compare cost and benefits<br />Decide on which controls to install<br />Cost Benefit Analysis<br />
  13. 13. Intended to:<br />Prevent accidental hazards<br />Deter intentional acts<br />Detect problems ASAP<br />Enhance damage recovery<br />Correct problems comprehensively<br />Controls to Mitigate Risk<br />
  14. 14. Increasing the Reliability of Systems<br />Fault tolerance to keep the information systems working, even if some parts fail. <br />Intelligent Systems for <br />Early Detection of problems<br />Detecting intrusion<br />IT Security in the 21st Security<br />
  15. 15. Why do we need to back up systems?<br />Because systems fail<br />Impact <br />From minor irritation to business closedown<br />Back up system to: <br />Periodic in Local storage<br />Periodic in Remote storage<br />Mirror site – local<br />Mirror site – distant<br />Withstand fault tolerance<br />Backing-up Systems<br />
  16. 16. System Disaster – it happens!<br />Think about:<br />Loss of power<br />Cyber crime<br />Traumatic damage<br />Hardware failure<br />Statutory Requirement<br />
  17. 17. System Recovery and Business Continuity<br />Is there a relationship between the two?<br />Here are some key thoughts about disaster recovery by Knoll (1986):<br />The purpose of a recovery plan is to keep the business running after a disaster occurs<br />Recovery planning is part of asset protection<br />Planning should focus first on recovery from a total loss of all capabilities<br />
  18. 18. How to ensure that the recovery system works<br />Proof of capability usually involves some kind of what-if analysis that shows that the recovery plan is current<br />All critical applications must be identified and their recovery procedures addressed in the plan<br />
  19. 19. Disaster Recovery Plan<br />In other words: BACK UP PROCEDURES<br />In the event of a major disaster it may be necessary to move to another back up location.<br />
  20. 20. Disaster Recovery Plan Considerations<br />Customers<br />Facilities<br />Communications<br />Infrastructure<br />Disaster <br />Recovery<br />Plan<br />Knowledge<br />Workers<br />Computer<br />Equipment<br />Business<br />Information<br />PGM<br />
  21. 21. Disaster Recovery Plan<br />HOT SITE VENDORS<br />External hot site vendors provide access to a fully configured back up data center.<br />Following the 1989 San Francisco earthquake Charles Schwab were up and running in New Jersey the following morning.<br />PGM<br />
  22. 22. Disaster Recovery Plan<br />COLD SITE VENDORS<br />Provide empty office space with special flooring, wiring and ventilation.<br />In an emergency the affected company moves its own or leased computers to the cold site.<br />These back up sites may work well for a company with centralised computing facilities but what can a company with a distributed network system do?<br />PGM<br />
  23. 23. Physical access control<br />Uninterrupted power supply (UPS)<br />Generator<br />Humidity control<br />Temperature control<br />Water Detector<br />Raised Floors<br />Fire Extinguisher <br />Alarm<br />Methods to Control & Secure I.S.<br />PGM<br />
  24. 24. THINGS TO TAKE NOTE OFF<br />Risk management approach (the 5 steps)<br />What are the different risk mitigation controls?<br />Types of back-up systems<br />What is a disaster recovery plan?<br />What should be considered in a disaster recovery plan?<br />
  25. 25. Managing System Security<br />
  26. 26. IT’S TIME FOR SOME DISCUSSIONS!<br />List and briefly describe the steps involved in risk analysis of controls.<br />Define and describe a disaster recovery plan.<br />What are “hot” and “cold” recovery sites?<br />Explain why risk management should involve the following elements: threats, exposure associated with each threat, risk of each threat occurring, and cost of controls, as well as assessment of their effectiveness.<br />Why should information control and security be a prime concern to management?<br />
  27. 27. IT’S TIME FOR ANIN-CLASS ACTIVITY!<br />Get into groups of 5-6 members<br />Using the Risk Management Approach (5-Steps), apply it to your company / one company of your choice as below:<br />GSC Cinemas Ticketing / Fashion Retail (brick-and-mortar) / IBM / Malaysian Airlines Ticketing / Hilton Hotel Reservation / Facebook<br />Suggest which Risk Mitigation Control should you implement and how it can help you mitigate your risk<br />Present your approach the class<br />
  28. 28. Coming soon… next class<br />ManagementInformation Systemsin Organizations<br />DISASTER<br />RECOVERY PLAN<br />What is a disaster recovery plan? How does it minimize risk?<br />
