Detailed risk analysis

Currently, CobiT does not include a risk analysis methodology.

Risks are determined from evaluating the threats (deliberate or accidental), the vulnerability, and the business consequence to the organisation in this regard. The primary role of risk analysis is to support the selection of controls:
to counter the unique set of security risks to the organisation's assets
to meet statutory and contractual requirements
to conform with the organisation's unique set of principles, objectives and requirements for information processing

Assessment of risk should take into account:
the nature of the business information and systems
the business purpose for which the information is used
the environment in which the system is used and operated
the protection provided by the controls in place.

1. Threats

2. Vulnerability

Dependence on information technology
Networks present opportunities for access
Distributed processing as central control is reduced

3. Business Consequences

Business consequences of potential breaches in security can be categorised as either operational, financial loss or intangible consequences. Examples of these are listed below.

Embarrassment
Wages, Salaries and Pensions not paid leading to industrial action
Breach of confidentiality
Unavailability of services
Loss of processing facilities
Loss of supplier, employee, investor and customer confidence

Loss of Revenue
Delayed banking, invoicing, collecting leading to interest loss
Increased uncollectible debts
Subsidies not being claimed

Increased Cost of Business
Loss of data and the associated recovery time Additional cost of processing back-logs
Legal costs
Penalties for failing to comply with statutory or contractual obligations
Additional public relations costs

Financial Misstatement
Property valuations
Inaccurate processing, data corruption or loss of system integrity
Inaccurate costing systems

Competitive disadvantage
Loss of business
Loss of customers
Legal Liability
Public liability Loss of Public Trust
Grossly inaccurate processing
Major scandal Regulatory, Statutory or Contractual Liability
Lack of provision of adequate services
Copyright legislation
Data Protection legislation
Public Accountability

4. Business Impact

Where required, this would be a measure of the financial losses arising from both tangible and intangible consequences suffered by an organisation.

Generally, a minimum or "Baseline" level of controls should be in place to provide an adequate and necessary degree of protection for the majority of situations. CobiT is often the basis for this minimum level of control

In response to specific threats identified through a risk analysis exercise, additional countermeasures may be warranted at times. Further controls would be necessary where there are legal and contractual obligations, as well as when there is a need to maintain professional standards of good practice.
