All risk management activities as presented from Clause 7 to Clause 12 are structured as follows:
Input: Identifies any required information to perform the activity.
Action: Describes the activity.
Implementation guidance: Provides guidance on performing the action. Some of this guidance may not be suitable in all cases and so other ways of performing the action may be more appropriate.
Qutput: Identifies any information derived after performing the activity.
A systematic approach to information security risk management is necessary to identify organizational needs regarding information security requirements and to create an effective information security management system (ISMS). This approach should be suitable for the organization’s environment and, in particular, should be aligned with overall enterprise risk management. Security efforts should address risks in an effective and timely manner where and when they are needed. Information security risk management should be an integral part of all information security management activities and should be applied both to the implementation and the ongoing operation of an ISMS.
Information security risk management should be a continual process. The process should establish the external and internal context, assess the risks and treat the risks using a risk treatment plan to implement the recommendations and decisions. Risk management analyses what can happen and what the possible consequences can be, before deciding what should be done and when, to reduce the risk to an acceptable level.
Information security risk management should contribute to the following:
– risks being identified;
– risks being assessed in terms of their consequences to the business and the likelihood of their occurrence;
– the likelihood and consequences of these risks being communicated and understood;ISO 27005 pdf download.
