Explanation:
Normally, the designing of an information systems security policy is the responsibility of top management or the board of directors. The IS department is responsible for the execution of the policy, having no authority in framing the policy. The security committee also functions within the broad security policy framed by the board of directors. The security administrator is responsible for implementing, monitoring and enforcing the security rules that management has established and authorized.

Explanation
Zero-day exploits tend to be very difficult to detect. Antimalware software and some intrusion detection systems (IDSes) and intrusion prevention systems (IPSes) are often ineffective because no attack signature yet exists. This is why the best way to detect a zero-day attack is user behavior analytics.

Explanation
A balanced scorecard is a strategic planning framework that companies use to assign priority to their products, projects, and services; communicate about their targets or goals; and plan their routine activities1. The scorecard enables companies to monitor and measure the success of their strategies to determine how well they have performed. A balanced scorecard for IT management can help assess IT functions and processes by defining four perspectives: financial, customer, internal business process, and learning and growth2. These perspectives can help IT management align their IT objectives with the organization's vision and mission, identify and prioritize the key performance indicators (KPIs) for IT, and evaluate the effectiveness and efficiency of IT operations and services3.

The IS auditor should first determine whether the business impact analysis (BIA) is current with the organization's structure and context. The BIA is a critical component of the BCP and should reflect the current state of the organization. If the BIA is not up-to-date, it may not accurately reflect the impact of a disruption to the organization's operations, including the closure of a production plant12.
