Authenticating the site to be surfed is the primary goal of a web certificate. Authentication of a user is achieved through passwords and not by a web site certificate. The site certificate does not prevent hacking nor does it authenticate a person.

The most important consideration for an IS auditor when scheduling follow-up activities for agreed-upon management responses to remediate audit observations is the risk rating of original findings. The risk rating of original findings is an assessment of the potential impact or likelihood of an audit issue or observation on the organization's objectives, operations, or reputation. The risk rating of original findings can help determine the priority and urgency of follow-up activities for agreed-upon management responses to remediate audit observations by ensuring that high-risk issues are addressed first and more frequently than low-risk issues.
The other options are not as important as the risk rating of original findings in scheduling follow-up activities for agreed-upon management responses to remediate audit observations, as they do not reflect the significance or severity of audit issues or observations. Business interruption due to remediation is a possible consequence of implementing corrective actions to address audit issues or observations, but it does not indicate the priority or urgency of follow-up activities. IT budgeting constraints is a possible factor that may affect the availability or feasibility of resources for implementing corrective actions to address audit issues or observations, but it does not indicate the priority or urgency of follow-up activities. Availability of responsible IT personnel is a possible factor that may affect the accountability or responsiveness of staff for implementing corrective actions to address audit issues or observations, but it does not indicate the priority or urgency of follow-up activities.
