An engineering team is building an application that handles sensitive records across a distributed environment. Which approach makes the data unreadable if intercepted?
Store user entries using hashing
Enable encryption for requests
Block suspicious connections with a firewall
Permit logins from fixed IP addresses
Encryption at the transport layer, known as Transport Layer Security (TLS), helps ensure that information remains hidden from unwanted parties as it moves. A hashing function focuses on data integrity and does not conceal content during transfer. A firewall can reject certain traffic but does not obscure the details of the data. Restricting logins by IP range limits who can connect but does not secure the data if someone manages to observe the traffic.
