Which of the following is true about the containment policy?

The containment policy in a cybersecurity context is primarily designed to manage how a network responds to detected threats. The assertion that it allows specific network traffic is true, as the policy is strategically set to limit or allow certain types of communications based on security requirements. This might include enabling trusted applications or necessary operational communications while restricting others that could be deemed harmful or suspicious.

In a well-designed containment policy, the objective is to balance operational needs while minimizing potential exposure to threats. This selective allowance of network traffic helps in containing the threat without entirely cutting off necessary functions or services, thereby maintaining productivity and ensuring that business-critical operations are still able to function effectively within a secure framework.
