A security analyst is reviewing data protection policies. The analyst notes that data can exist in three primary states: at rest, in transit, and in use. In which of these states is data generally most vulnerable to interception attacks?
Data in use
Data at rest
Obfuscated data
Data in transit
Data is generally considered most vulnerable to interception when it is 'in transit'. This state, also known as 'data in motion', describes data being transferred over a network. During transit across local or public networks, data is susceptible to being captured, read, or altered by unauthorized parties if not properly encrypted. While data 'at rest' (stored) and 'in use' (being processed) have their own significant vulnerabilities, the act of moving data between systems often exposes it to the widest range of network-based threats. Security measures like TLS and IPsec are crucial for protecting data in this state.
