The greatest risk associated with an incomplete inventory of deployed software in an organization is the inability to deploy updated security patches. Security patches are updates that fix vulnerabilities or bugs in software that could be exploited by attackers. Without an accurate inventory of software versions and config urations, it is difficult to identify and apply the relevant patches in a timely manner, which exposes the organization to increased security risks. Inability to close unused ports on critical servers, inability to identify unused licenses within the organization, and inability to determine the cost of deployed software are not as critical as security risks.

The primary responsibility of a project steering committee is to provide regular project updates and oversight.
A project steering committee is an advisory group that consists of senior stakeholders and experts who offer guidance and support to a project manager and their team. The steering committee is mainly concerned with the direction, scope, budget, timeline, and methods used to realize a given project1.
One of the key roles of a steering committee is to monitor the progress and performance of the project and ensure that it aligns with the business objectives and stakeholder expectations. The steering committee also provides feedback, advice, and recommendations to the project manager and helps them resolve any issues or challenges that may arise during the project lifecycle. The steering committee communicates regularly with the project manager and other stakeholders through meetings, reports, and presentations23.
Therefore, providing regular project updates and oversight is the primary responsibility of a project steering committee.

The best method to delete sensitive information from storage media that will be reused is multiple overwriting. This is because multiple overwriting ensures that the data is practically unrecoverable by any software or hardware means. Multiple overwriting involves writing 0s, 1s, or random patterns onto all sectors of the storage media several times, making the original data unreadable or inaccessible. There arevarious software programs available that can securely delete files from storage media using multiple overwriting techniques1.
Crypto-shredding is not the best method because it only works for encrypted data. Crypto-shredding involves deleting the encryption key used to encrypt the data, making the data unreadable and unrecoverable. However, if the data is not encrypted, crypto-shredding will not erase it2.
Reformatting and re-partitioning are not the best methods because they do not erase the data completely. Reformatting and re-partitioning only delete the file system structures and pointers that make the data accessible, but thedata itself remains on the storage media and can be recovered using data recovery software

The internal audit manager should have a reporting line to the audit committee, which is an independent body that oversees the internal audit function and ensures its objectivity and accountability. Reporting functionally to a senior management official may compromise the independence and clarity of the internal audit reporting process, as senior management may have a vested interest in the audit results or influence the audit scope and priorities. *References: According to the ISACA IT Audit and Assurance Standards, Guidelines and Tools and Techniques for IS Audit and Assurance Professionals, section 1002 Independence, "The chief audit executive (CAE)should report functionally to the board or its equivalent (e.g., audit committee) and administratively to executive management." 1

The greatest concern for an IS auditor when reviewing IT policies and procedures that are not regularly reviewed and updated is that policies and procedures might not reflect current practices. Policies are documents that define the goals, objectives, and guidelines for an organization's information systems and resources. Procedures are documents that describe the steps, tasks, or activities for implementing or executing policies. Policies and procedures should be regularly reviewed and updated to ensure that they are relevant, accurate, consistent, and effective for the organization's information systems and resources. Policies and procedures that are not regularly reviewed and updated might not reflect current practices, as they might be outdated, obsolete, or incompatible with the current state or needs of the organization's information systems and resources. This can cause confusion, inconsistency, inefficiency, or noncompliance among users or stakeholders who rely on policies and procedures for guidance or direction. Policies and procedures might not include new systems and corresponding process changes is a possible concern for an IS auditor when reviewing IT policies and procedures that are not regularly reviewed and updated, but it is not the greatest one. Policies and procedures might not include new systems and corresponding process changes, as they might be unaware of or unresponsive to the introduction or modification of information systems or resources within the organization. This can cause gaps, overlaps, or conflicts among policies and procedures that affect different information systems or resources.
