A. B. C. D.A.
As business objectives and methods change, the nature and relevance of threats change as well.
Choice B does not, by itself, justify regular reassessment.
Choice C is not necessarily true in all cases.
Choice D is incorrect because there are better ways of raising security awareness than by performing a risk assessment.
A security risk assessment exercise should be repeated at regular intervals because of the following reasons:
A. Business threats are constantly changing: Threats to an organization's security can arise at any time, and new ones can appear frequently. For example, new technologies or techniques may emerge that could be used to exploit existing vulnerabilities. Regular risk assessments enable an organization to identify and address new risks as they emerge, ensuring that the security posture of the organization stays up-to-date and relevant.
B. Omissions in earlier assessments can be addressed: Risk assessments are not perfect, and they are based on assumptions and available data at the time of the assessment. However, as new data is gathered, and assumptions are proven wrong, the risk assessment may need to be adjusted. By repeating risk assessments at regular intervals, an organization can address any omissions or errors in earlier assessments.
C. Repetitive assessments allow various methodologies: Different methodologies and tools can be used to perform security risk assessments, and these can produce different results. Repeating assessments at regular intervals can allow an organization to use various methodologies and compare results. This can help to identify any gaps in coverage or inconsistencies in the data, leading to more comprehensive and accurate risk assessments.
D. They help raise awareness on security in the business: Conducting regular risk assessments can help to raise awareness about the importance of security within an organization. It can also help to foster a security culture by involving employees in the assessment process and encouraging them to identify potential risks. This can ultimately lead to better security practices and a more secure environment for the organization.
In conclusion, a security risk assessment exercise should be repeated at regular intervals to ensure that the security posture of an organization stays up-to-date, to address any omissions or errors in earlier assessments, to allow for the use of various methodologies, and to raise awareness of security within the organization.
