= After a breach where the risk has been isolated and forensic processes have been performed, the next step should be to rebuild the server from the last verified backup. This will ensure that the server is restored to a known and secure state, and that any malicious code or data that may have been injected or compromised by the attacker is removed. Rebuilding the server from the original media may not be sufficient, as it may not include the latest patches or configurations that were applied before the breach. Placing the web server in quarantine or shutting it down may not be feasible or desirable, as it may disrupt the business operations or services that depend on the server. Rebuilding the server from the last verified backup is the best option to resume normal operations while maintaining security. References = CISM Review Manual 15th Edition, page 118: "Recovery is the process of restoring normal operations after an incident. Recovery activities may include rebuilding systems, restoring data, applying patches, changing passwords, and testing functionality." Data Breach Experts Share The Most Important Next Step You Should Take After A Data Breach in 2014 &
2015, snippet: "Restore from backup. If you have a backup of your system from before the breach, wipe your system clean and restore from backup. This will ensure that any backdoors or malware installed by the hackers are removed."

A business impact analysis (BIA) provides results, such as impact from a security incident and required response times. The BIA is the most critical process for deciding which part of the information system/ business process should be given prioritization in case of a security incident. Risk assessment is a very important process for the creation of a business continuity plan. Risk assessment provides information on the likelihood of occurrence of security incidence and assists in the selection of countermeasures. but not in the prioritization. As in choice B, a vulnerability assessment provides information regarding the security weaknesses of the system, supporting the risk analysis process. Business process mapping facilitates the creation of the plan by providing mapping guidance on actions after the decision on critical business processes has been made-translating business prioritization to IT prioritization. Business process mapping does not help in making a decision, but in implementing a decision.

Two-factor authentication through the use of strong passwords combined with security tokens provides the highest level of security. Data encryption, digital signatures and strong passwords do not provide the same level of protection.

The factor that has the greatest influence on the successful integration of information security within the business is organizational structure and culture because they determine how information security is organized, governed, and supported within the organization, and how information security roles and responsibilities are defined, assigned, and communicated across different levels and functions. Risk tolerance and organizational objectives are not very influential because they do not affect how information security is integrated within the business, but rather what information security aims to achieve or protect. The desired state of the organization is not very influential because it does not affect how information security is integrated within the business, but rather what the organization aspires to be or do. Information security personnel are not very influential because they do not affect how information security is integrated within the business, but rather who performs information security tasks or activities.
