What approach does QRadar take when it imposes EPS license (not hardware) limits on events that temporarily spike above that limit?
What approach does QRadar take when it imposes EPS license (not hardware) limits on events that temporarily spike above that limit?
When QRadar encounters a temporary spike in events per second (EPS) that exceeds the licensed limit, it handles the excess events by writing them to a queue. These queued events are then processed once the EPS rate drops back within the licensed threshold. This approach ensures that no data is lost during spikes and that the system can handle temporary increases in event rates efficiently.
What is an approach to tuning a “noisy” rule, that is, a rule that generates too many offenses?
To tune a 'noisy' rule, which indicates a rule generating too many false positives or offenses, the ideal approach is to determine whether the rule is matching too many conditions in the traffic. This involves analyzing the rule's criteria and conditions to ensure they are appropriately specific to reduce the number of irrelevant matches. This helps in refining the rule to be more precise and effective.
Which of these statements is true about network objects?
A network object can have multiple CIDR ranges assigned to it. This indicates that a network object can encompass multiple subnets or IP ranges, which is often necessary for representing different segments or areas within an organization's network. This flexibility allows for more precise network management and monitoring.
A QRadar deployment professional designs a multi-tenant environment where each tenant is permitted a quantity of events per second (EPS).
In a discussion with the service provider (who provides the security monitoring services to each tenant), how should the deployment professional describe the licensing options available?
Per-tenant EPS limits can be set if the tenants are defined by event collectors. Then over-license buffering can be used to handle EPS spikes. This explanation accurately reflects how a multi-tenant environment can manage EPS limits effectively by utilizing event collectors, which can also handle temporary spikes in EPS due to the ability to use over-license buffering.
What is the directory where a backup archive file needs to be placed so that QRadar can automatically import it?
The correct directory where a backup archive file needs to be placed for QRadar to automatically import it is /store/imports/inbound. QRadar monitors this specific directory to detect and import backup archive files.
