Campus routers exchange routing updates and device management using protocols with authentication disabled, allowing trivial spoofing of peers. Which action best hardens protocol selection and configuration?
Select an answer to reveal the explanation.
Short Explanation
Unauthenticated routing updates are like taking street signs from strangers. Turn on protocol authentication, shut what you don’t need, and stop managing gear with museum cleartext protocols.
Full Explanation
Protocol choice and configuration have direct security implications: unauthenticated routing or management protocols enable spoofing, session hijacking, and unauthorized reconfiguration. Enabling authentication features, removing unused services, and migrating from cleartext management protocols reduce those risks. Convenience-oriented open management from untrusted networks is incompatible with secure municipal infrastructure operation.
