A security incident has been reported within an organization When should an information security manager...

= An information security manager should contact the information owner after the incident has been confirmed, as this is the point when the impact and severity of the incident can be assessed and communicated. The information owner is responsible for the business value and use of the information and should be involved in the decision making process regarding the incident response. Contacting the information owner after the incident has been mitigated or contained may be too late, as the information owner may have different priorities or expectations than the security team. Contacting the information owner after the potential incident has been logged may be premature, as the incident may turn out to be a false positive or a minor issue that does not require the information owner’s attention. References = 1: CISM Review Manual, 16th Edition by Isaca (Author), page 292.
