Which action will meet the requirement while ensuring that traffic unrelated to the specific application is not matched?
A) Add specific applications that are seen when creating cloned rules.
B) Create a custom application and define it by the correct TCP and UDP ports.
C) Add the relevant container application when creating cloned rules.
D) Create an application filter based on the existing application category and risk.
Answer (2)
To ensure that only traffic related to a specific application is matched, excluding unrelated traffic, the best action is to B) Create a custom application and define it by the correct TCP and UDP ports.
Here's why this option is the most effective:
Specificity: By creating a custom application, you can precisely define the characteristics of the traffic you wish to match. This includes specifying the exact TCP and UDP ports used by the application, which ensures that only traffic for those ports is matched by the rule.
Exclusion of Unrelated Traffic: Other options, such as adding specific applications seen when cloning rules or creating application filters based on existing categories and risks, might not be as precise. They could potentially match additional traffic that shares some attributes with the intended application, leading to false positives.
Control: A custom application gives you full control over the criteria that must be met for traffic to be considered a match. This reduces the potential for error and increases the accuracy of rule application.
Security and Performance Optimization: Ensuring only relevant traffic is processed by the rule helps in optimizing both security measures and system performance by reducing unnecessary processing of unrelated traffic.
In summary, creating a custom application defined by specific ports allows for precise traffic filtering, ensuring that only the intended traffic is matched while excluding unrelated data. This approach is particularly effective in networks that require stringent traffic control and security measures.
The best action to match only traffic for a specific application while excluding unrelated traffic is to create a custom application defined by the correct TCP and UDP ports. This approach increases specificity, reduces false positives, and optimizes network performance. Therefore, the chosen option is B.
