It is essential to consider that proper incident response is input as an integral part of the overall security policy and risk mitigation plan. The steps that would be essential to respond to this potential risk would involve:
- Minimize the severity and number of potential incidents; it is essential to prevent security issues, though sometimes the prevention is not 100%; however, a regular check-up and documentation can assist in narrowing the incident case and minimize the severity in time.
- Assemble the core computer security incident team to assist in handling the situation as quick as possible (Stewart et al., 2012). They do this by determining the source of incident either by interrogating whoever discovered the worm for more information or carrying out an independent investigation.
- Define the incident response plan or strategy. IR team members must be aware of the strategy of handling the incident through identification, assessment, communication, evident protection, and compilation of incident documentation.
- Last step is to prevent damage and minimize the risks. This is achieved through a quick response to the incident situation and managing it properly by the responsible team (Stewart et al., 2012).
In summary, the steps involve discovery, documentation, notification, acknowledgement, containment investigation, resolution, and closure (Vacca, 2013).

The Incident Recovery Processes for the Resolution
This best practice gives the requirements for the formation and containment of the Incident Response Process (IRP) essential to guard the integrity, confidentiality, and availability of the organization’s data and information procedures. The Position of Authority for Information processes or department for each respective organization are accountable for the development of the Standard Operating Procedure (SOP) and the Incident Response Process (IRP) (Prosise & Mandia, 2003).
An IRP is created to accomplish the following objectives:
- Substantiate whether an incident has happened
- Promote the build-up of correct information
- Institute controls for the appropriate retrieval and management of evidence
- Minimize disturbance to business operations and network functions
- Permit for lawful enforcement and actions against culprits
- Give precise reports and functional recommendations (Prosise & Mandia, 2003).
The incident recovery process involves identification of the scope of incidence and related risks. Resources together with the personnel responsible for incident response are noted immediately for a proper containment and resolution. Pre-incident preparation is expected to be done before the actual occurrence (Prosise & Mandia, 2003). This is a means of ensuring business continuity after a disaster occurrence. All employees are involved in disaster management in one way or the other. The Incident Response Process in every organization or institute is facilitated by the classification of the data or information as defined in the data categorization strategy, as well as the categorization of the systems used, as classified in the System Taxonomy Policy. Higher stages of classification necessitate higher standards of responsibility.
Preparation is a key step in IR and must be done prior to the incidence so as to ensure the proper incidence response process.
