This should result in a finding because it violates the best practice of setting rules for groups rather than users. According to one of the web search results1, using group permissions instead of individual permissions can simplify the management and maintenance of ACLs, reduce the risk of human errors, and ensure consistency and compliance. Individual permissions can create conflicts, confusion, and security gaps in the ACLs. Therefore, the IS auditor should report this as a finding and recommend using group permissions instead.

The most effective control to protect information assets in a data center from theft by a vendor is to monitor and restrict vendor activities. A vendor may have legitimate access to the data center for maintenance or support purposes, but they may also have malicious intentions or be compromised by an attacker. By monitoring and restricting vendor activities, the organization can ensure that the vendor only performs authorized tasks and does not access or tamper with sensitive data or equipment. Issuing an access card to the vendor, concealing data devices and information labels, and restricting use of portable and wireless devices are also useful controls, but they are not as effective as monitoring and restricting vendor activities in preventing theft by a vendor.

The greatest risk of using a reciprocal site for disaster recovery is the inability to utilize the site when required. A reciprocal site is an agreement between two organizations to provide backup facilities for each other in case of a disaster. However, this arrangement may not be reliable or enforceable, especially if both organizations are affected by the same disaster or have conflicting priorities. Therefore, the IS auditor should recommend that management consider alternative options for disaster recovery, such as dedicated sites or cloud services12. References:

Residual risk from the findings of previous audits should be the primary basis for prioritizing follow-up audits, because it reflects the level of exposure and potential impact that remains after management has implemented corrective actions or accepted the risk. Follow-up audits should focus on verifying whether the residual risk is within acceptable levels and whether the corrective actions are effective and sustainable. Audit cycle defined in the audit plan, complexity of management's action plans, and recommendation from executive management are not valid criteria for prioritizing follow-up audits, because they do not consider the residual risk from previous audits.
