The cryptographic protocol abbreviated as _____ succeeded Secure Sockets Layer (SSL) to provide encryption for protecting sensitive data in transit.
Answer
TLS
Explanation
### Why this is right
The material names Transport Layer Security (TLS), HTTPS enforcement, and HSTS policies as measures for protecting data in transit. TLS protects communication between endpoints by encrypting the transmission.
### The concept
Data in transit is information moving between systems. Without encryption, someone who intercepts the communication may read sensitive information, and data may be altered during transit. TLS is used to protect communications; HTTPS is the secure form of web communication that uses such protection. HSTS policies tell browsers to use secure HTTPS connections for a site.
### Terms
- **TLS**: Transport Layer Security. A protocol used to protect data sent between systems.
- **HTTPS**: Hypertext Transfer Protocol Secure. Web communication protected using encryption.
- **HSTS**: HTTP Strict Transport Security. A policy that directs browsers to use secure HTTPS connections for a site.
### Remember
For sensitive information moving between systems, protect the channel as well as the stored data.
