How can users set rules for notifications regarding vulnerability updates?

Setting rules for notifications regarding vulnerability updates is accomplished through the configuration of notification conditions in ServiceNow. This approach allows users to customize how and when they receive alerts based on criteria they define, such as the severity of vulnerabilities, the specific assets affected, or changes in vulnerability status. This finely-tuned control ensures that notifications are relevant and timely, helping users respond effectively to threats.

The other options present different processes that do not directly relate to configuring notifications. Subscribing to external vulnerability feeds is focused on receiving information from outside sources rather than governing how notifications are managed within ServiceNow itself. Assigning notifications to specific users manually lacks the automation and specificity needed for dynamic environments where vulnerabilities can change frequently. Lastly, enabling global settings in system preferences might impact broader system behaviors but does not provide the specific functionality needed for setting granular notification rules related to vulnerability management.
