A national analytics firm handles confidential records that must remain unreadable while traveling between various remote sites. The security lead seeks an approach that addresses eavesdropping over shared network infrastructure. Which method best accomplishes this goal?
Implement a negotiation-based public-key method that creates session-specific keys
Exchange credentials without encryption to maintain compatibility between sites
Implement regular data backups to safeguard sensitive information from exposure
Adopt a pre-shared key approach used consistently at each location
A negotiation-based public-key method for session-specific keys ensures each connection has a unique key, lowering the risk that a compromised session key compromises future transmissions. A pre-shared key puts traffic at higher risk if the key is disclosed. Exchanging credentials without encryption leaves them vulnerable to interception. Regular backups protect data at rest but do not secure information while in motion.
