Definitions …1 Crisis: An abnormal situation which threatens the operations, staff, customers or reputation of the enterprise. Incident: An event that has the capacity to lead to loss of or a disruption to an organization’s operations, services, or functions – which, if not managed, can escalate into an emergency, crisis or disaster. 8

Definitions …2 Disaster: An unplanned interruption of normal business process. Risk: Combination of the probability of an event and its consequence. Vulnerability: The degree to which a person, asset, process, information, infrastructure or other resources are exposed to the actions or effects of a risk, event or other occurrence. 9

Definitions …3 Incident Management Plan: A clearly defined and documented plan of action for use at the time of an incident, typically covering the key personnel, resources, services and actions needed to implement the incident management process. Disaster Recovery Planning: A disaster recovery plan (DRP) is a documented process or set of procedures to recover and protect a business IT infrastructure in the event of a disaster.

10

Definitions …4 Business Continuity Planning: Business continuity planning is the process of developing prior arrangements and procedures that enable an organization to respond to an event in such a manner that critical business functions can continue within planned level of disruption.

Business Continuity Management: A holistic management process that identifies potential threats to an organization and the impacts to business operations that those threats – if realized – might cause, and which provides a framework for building organizational resilience with the capability for an effective response that safeguards the interests of its key stake holders, reputation, brand, and value-creating activities. 11

BCP Manual Documented description of actions to be taken Resources to be used and Procedures to be followed before, during and after a disruptive event. BCP Manual specifies the responsibilities of the BCM team which serve as liasoning teams between the functional area(s) affected and other departments providing support services in the event of an incident or disaster. 15

BCP Manual BCM is a framework that • Proactively improves an enterprise’s resilience against the disruption of its ability to achieve its key objectives. • Provides a rehearsed method of restoring an enterprise’s ability to supply its key products and services to an agreed level within an agreed time after a disruption. • Delivers a proven capability to manage a business disruption and protect the enterprise’s reputation and brand. 16

BCM Policy

A high level document To bring about awareness among To test and review To make a the persons in the business systematic continuity planning scope about the approach for business continuity for the enterprise disaster recovery aspects and its in scope. importance 17

BCM Policy Objective of this policy is to provide a structure through which • Critical services and activities will be identified. • Plans will be developed to ensure continuity of key service delivery following a business disruption. • Invocation of incident management and business continuity plans can be managed.

• Incident management and business continuity plans are subject to ongoing testing, revision and updation. • Planning and management responsibility are assigned to a member of the relevant senior management team. 18

Objectives and Goals of BCP Primary Objectives of BCP • To minimize loss by minimizing the cost associated with disruptions • To enable an organisation to survive a disaster • To re-establish normal business operations 19

Need for BCM Business Point of View • Heavy Dependence on Information, Communication and technologies • To ensure that critical business functions will be available to customers, suppliers, regulators, and other entities that must have access to those functions • To maintain service, consistency, and recoverability. • Critical industries like Banks, Insurance Companies, Stock Exchanges, Airline Companies, Railways, Multinational Companies, Government Agencies rely on IT Infrastructure 32

Need for BCM Information Technology Mail Servers and Communication lines like Internet, Phone and Fax are also essentially the important components of the Infrastructure. Critical IT Resources like Servers, Workstations, Network and Communication, Operating system software, business applications software, essential utility software, Data Centers, Support Desks, IT Personnel, Disks, Tapes etc. Software like the Core Banking Systems, SWIFT Financial Messaging Services, Airline Communication Services, Stock Market Trading Applications, ERP Systems, e-commerce sites and many more are critical where no downtime is tolerated.

33

Need for BCM Key terms • Business Contingency • An event with the potential to disrupt computer operations, thereby disrupting critical mission and business functions • Eg. power outage, hardware failure, fire, or storm. If the event is very destructive, it is often called a disaster 34

Need for BCM Key terms • BCP Process • A process designed to reduce the risk to an enterprise from an unexpected disruption of its critical functions and assure continuity of minimum level of services necessary for critical operations

• Purpose is to ensure that vital business functions (critical business operations) are recovered and operationalized within an acceptable timeframe 35

Need for BCM Key terms • Business Continuity Planning (BCP)

• Ability of enterprises to recover from a disaster and continue operations with least impact • Independent audit to confirm adequacy and appropriateness to meet enterprise needs 36

Disaster 

A disruption of business operations that stops an organization from providing critical services caused by the absence of critical resources.



A disaster is a natural or man-made (or technological) hazard resulting in

an event of substantial extent causing significant physical damage or destruction, loss of life, or drastic change to the environment 

Vulnerabilities are weaknesses

associated with an organization’s assets. 37

Types of Disasters Natural Disaster E.g. fire, earthquake, tsunami, typhoon, floods, tornado, lightning,

Summary The management of Business Continuity Plans, Disaster Recovery Plans and Incident Responses are collectively known as Business Continuity management.

The ultimate objective of a BCM is to recover from a crisis as fast as possible and at the lowest possible cost. Business Continuity is applicable to organizations of all sizes and types of business. Business Continuity is most crucial to enterprises which employ a lot of IT Resources for their critical business functions. 42

Summary Disaster is an event that causes interruption to the ongoing business functions which is either natural or manmade. Disaster would normally go through Crisis Phase, Emergency Response Phase, Recovery Phase and Restoration Phase. 43

Questions

44

1. An organization's disaster recovery plan should address early recovery of: A. B. C. D.

All information systems processes. All financial processing applications. Only those applications designated by the IS Manager. Processing in priority order, as defined by business management.

Answer: D Business management should know what systems are critical and when they need to process well in advance of a disaster. It is their responsibility to develop and maintain the plan. Adequate time will not be available for this determination once the disaster occurs. IS and the information processing facility are service organizations that exist for the purpose of assisting the general user management in successfully performing their jobs. 45

2.

Which of the following is MOST important to have in a disaster recovery plan?

A. B. C. D.

Backup of compiled object programs Reciprocal processing agreement Phone contact list Supply of special forms

Answer: A Of the choices, a backup of compiled object programs is the most important in a successful recovery. A reciprocal processing agreement is not as important, because alternative equipment can be found after a disaster occurs. A phone contact list may aid in the immediate aftermath, as would an accessible supply of special forms, but neither is as important as having access to required programs. 46

3. Which of the following BEST describes the difference between a disaster recovery plan and a business continuity plan? A. The disaster recovery plan works for natural disasters whereas the business continuity plan works for non-planned operating incidents such as technical failures. B. The disaster recovery plan works for business process recovery and information systems whereas the business continuity plan works only for information systems. C. The disaster recovery plan defines all needed actions to restore to normal operation after an un-planned incident whereas the business continuity plan only deals with critical operations needed to continue working after an un-planned incident. D. The disaster recovery plan is the awareness process for employees whereas the business continuity plan contains the procedures themselves to recover the operation. Answer: C The difference pertains to the scope of each plan. A disaster recovery plan recovers all operations, whereas a business continuity plan retrieves business continuity (minimum requirements to provide services to the customers or clients). Choices A, B and D are incorrect because the type of plan (recovery or continuity) is independent from the sort of disaster or process and it includes both awareness campaigns and procedures.

47

4. The MOST significant level of business continuity planning program development effort is generally required during the:

A. Early stages of planning. B. Evaluation stage. C. Maintenance stage. D. Testing Stage. Answer: A A company in the early stages of business continuity planning (BCP) will incur the most significant level of program development effort, which will level out as the BCP program moves into maintenance, testing and evaluation stages. It is during the planning stage that an IS Auditor will play an important role in obtaining senior management's commitment to resources and assignment of BCP responsibilities. 48

5.

A. B. C. D.

Disaster recovery planning for a company's computer system usually focuses on

Operations turnover procedures. Strategic long-range planning. The probability that a disaster will occur. Alternative procedures to process transactions.

Answer: D It is important that disaster recovery identify alternative processes that can be put in place while the system is not available.

49

6. A. B. C. D.

An unplanned interruption of normal business process is? Risk Vulnerability Disaster Resilience

Answer: C Disaster is event which interrupts business processes sufficiently to threaten the viability of the organization. Risk is a combination of the probability of an event and its consequence. Vulnerability is the degree to which a person, asset, process, information, infrastructure or other resources are exposed to the actions or effects of a risk, event or other occurrence. Resilience is the ability of an organization to resist being affected by the incident. 50

7. Which of the following strategy does not encompass disaster recovery plan ? A. B. C. D.

Preventive Detective Corrective Administrative

Answer: D There are three basic strategies that encompass a disaster recovery plan: preventive measures, detective measures, and corrective measures. Preventive measures will try to prevent a disaster from occurring. These measures seek to identify and reduce risks. Detective measures are taken to discover the presence of any unwanted events within the IT infrastructure. Their aim is to uncover new potential threats. Corrective measures are aimed to restore a system after a disaster or otherwise unwanted event takes place. 51

8.

Which of the following is not a fundamental of BCP?

A. Manage the risks which could lead to disastrous events. B. Minimize the risks involved in the recovery process. C. Reduce the costs involved in reviving the business from the incident D. Mitigate negative publicity Answer: D Mitigate negative publicity is an objective of Business continuity management is to rest all are the fundamental aim of BCP. 52

9. A. B. C. D.

Which phase starts with a damage assessment? Crisis Phase Emergency Response Phase Recovery Phase Restoration Phase

Answer: D Restoration phase will start with a damage assessment, usually within a day or so of the disaster, when the cause for evacuation or stopping of operations has ended, normal working will be restarted. During the Restoration Phase, any damage to the premises and facilities will be repaired. 53

10. Which of the following is of utmost important during an impact of disaster? A. B. C. D.

Loss of Productivity Loss of Revenue Loss of Human Life Loss of Goodwill & Market Share

Answer: C Protection of human life is of utmost importance and, the overriding principle behind continuity plans. Rest all are to be considered later.
