Explanation:
Resolving conflicts of this type should be based on a sound risk analysis of the costs and benefits of allowing or disallowing an exception to the standard. A blanket decision should never be given without conducting such an analysis. Enforcing existing standards is a good practice; however, standards need to be continuously examined in light of new technologies and the risks they present. Standards should not be changed without an appropriate risk assessment.

Decreasing false positives is the best indicator that the information security manager has tuned the system to address senior management's concern that the organization's intrusion prevention system (IPS) may repeatedly disrupt business operations. False positives are alerts generated by the IPS when it mistakenly blocks legitimate traffic or activity, causing disruption or downtime. Decreasing false positives means that the IPS has been configured to reduce such errors and minimize unnecessary interruptions. Increasing false negatives is not a good indicator because it means that the IPS has failed to detect or block malicious traffic or activity, increasing the risk of compromise or damage. Decreasing false negatives is not a good indicator because it does not affect business operations, but rather improves security detection or prevention. Increasing false positives is not a good indicator because it means that the IPS has increased its errors and interruptions, worsening senior management's concern.

Explanation
The effectiveness of virus detection software depends on virus signatures which are stored in virus definition tables. Software upgrades are related to the periodic updating of the program code, which would not be as critical. Intrusion detection and packet filtering do not focus on virus detection.
