What is a transport layer security (TLS)?

Table of contents

Transport Layer Security (TLS) refers to the cryptographic protocol that secures communication over computer networks. For payroll and payments, it ensures that sensitive data such as personal details or bank information can only be accessed by the intended recipient.

How does TLS work?

TLS works by creating a sort of secret language between the server and the client. That means any data sent is protected through a unique encryption.

In the context of payroll, the process can be broken down as follows:

  • Initiating a connection between a company’s payroll software and payroll service provider
  • Verification process of both parties through reputable digital IDs
  • Establishing a secret language between both parties though encryption
  • Exchanging data securely and ending the exchange

Difference between TLS and SSL

Secure Sockets Layer (SSL) is TLS’ predecessor. It is considered outdated because it supports older cipher suites and uses older legacy encryptions that are no longer considered secure.

Today, when people use the phrase ‘SSL’ they’re likely referring to TLS, as SSL is virtually no longer in use.

What are the risks of TLS?

The risks of TLS really boil down to using outdated versions of the protocol. Problems can include weak cyphers, certificate issues, or downgrade attacks.

In payroll, TLS risks can translate into compromised security, data breaches, and run-ins with compliance mishaps.

Suffice to say, it’s important to make sure you’re using the most up-to-date TLS to ensure optimal data security.
