Which of the following tasks is NOT usually part of a Business Impact Analysis (BIA)?
Correct Answer:
D
The Business Impact Analysis is critical for the development of a business continuity plan (BCP). It identifies risks, critical processes and resources needed in case of recovery and quantifies the impact a disaster will have upon the organization. The development of a mission statement is normally performed before the BIA.
A BIA (business impact analysis ) is considered a functional analysis, in which a team collects data through interviews and documentary sources; documents business functions, activities, and transactions ; develops a hierarchy of business functions; and finally applies a classification scheme to indicate each individual function??s criticality level.
BIA Steps
The more detailed and granular steps of a BIA are outlined here:
1. Select individuals to interview for data gathering.
2. Create data-gathering techniques (surveys, questionnaires, qualitative and quantitative approaches).
3. Identify the company??s critical business functions.
4. Identify the resources these functions depend upon.
5. Calculate how long these functions can survive without these resources.
6. Identify vulnerabilities and threats to these functions.
7. Calculate the risk for each different business function.
8. Document findings and report them to management.

A vulnerability characterizes the absence or weakness of a safeguard that could be exploited. This vulnerability may be a service running on a server, unpatched applications or operating system software etc.
The following answers are incorrect because:
Threat: A threat is defined as a potential danger to information or systems. The threat is someone or something will identify a specific vulnerability and use it against the company or individual. The entity that takes advantage of a vulnerability is referred to as a 'Threat Agent'. A threat agent could be an intruder accessing the network through a port on the firewall , a process accessing data that violates the security policy.
Risk:A risk is the likelihood of a threat agent taking advantage of a vulnerability and the corresponding business impact. If a firewall has several ports open , there is a higher likelihood that an intruder will use one to access the network in an unauthorized method.
Exposure: An exposure is an instance of being exposed to losses from a threat agent. REFERENCES:
