What is the main purpose of a DoS policy?

The main purpose of a DoS policy is to prevent Denial of Service attacks. DoS attacks are designed to overwhelm a network, service, or system, rendering it unavailable to legitimate users. A DoS policy is implemented to specifically detect and mitigate these types of attacks before they can disrupt services. This policy can include various countermeasures, such as rate limiting, filtering suspicious traffic, and blocking certain IP addresses or protocols associated with DoS methods.

While other options might play significant roles within network security, they are not the primary focus of a DoS policy. Traffic shaping rules are primarily concerned with managing bandwidth and ensuring efficient data flow rather than addressing the threats posed by DoS attacks. The management of firewall virtual wire pairs is related to network architecture and traffic management, while logging security incidents pertains to monitoring and incident response but does not address the proactive measures needed to prevent DoS attacks specifically.
