This is a valid option, and it is a popular choice for organizations that want to add IPS capabilities to their Cisco ASA firewall.

C. AIP-SSC: The AIP-SSC (Advanced Inspection and Prevention Security Services Card) is an IPS module that can be installed in certain Cisco routers and switches. It is not compatible with the Cisco ASA 5520 appliance, so this is not the correct answer.

D. NME-IPS-K9: The NME-IPS-K9 (Network Module Enhanced Intrusion Prevention System) is an IPS module that can be installed in certain Cisco routers and switches. It is not compatible with the Cisco ASA 5520 appliance, so this is not the correct answer.
