TLS
Transport Layer Security ”” the successor to SSL, providing encrypted communications over networks.
Also: Transport Layer Security
Definition
TLS (Transport Layer Security) is a cryptographic protocol that provides end-to-end security for data transmitted over the internet. It is the successor to SSL and is used to secure HTTP (HTTPS), email (SMTPS), messaging, and other protocols. TLS uses asymmetric cryptography to exchange keys and symmetric cryptography (AES) for bulk data encryption. TLS 1.3 (released 2018) significantly improved security and performance by reducing the TLS handshake to a single round-trip.
Example
“Every time you log into your bank online, TLS 1.3 establishes an encrypted channel in milliseconds before any data is transmitted.”
Usage Examples
- 1
“The team applied tls best practices to improve their cybersecurity outcomes significantly.”
- 2
“Understanding tls is essential for anyone building a career in IT & Technology.”
When & How to Use
Use 'TLS' when working in Cybersecurity contexts where tls (transport layer security) is a cryptographic protocol that provides end-to-end security for data transmitted over the internet.
- ▸Applying tls principles during a cybersecurity project or initiative
- ▸Explaining tls to a junior team member or stakeholder unfamiliar with IT & Technology
- ▸Evaluating options or proposals using tls as a decision-making criterion
Etymology & Origin
The term 'TLS' derives from professional usage and entered IT & Technology professional usage as the field formalised in the 20th century.
History & Evolution
The concept of tls has evolved alongside IT & Technology. Early practitioners relied on informal methods; structured approaches emerged with the professionalisation of cybersecurity in the mid-20th century. Today, tls is a standard part of IT & Technology practice globally.
