Why Is QuickBooks TLS 1.2 Version Preferred Over SSL/Early TLS?

Netscape introduced a secure Sockets Layer (SSL) in 1990. There were some differences in the SSL and early Transport Layer Security (TLS). This has made it easy for the attackers to take advantage of mainly the e-commerce platforms through widespread POODLE and BEAST exploits. It primarily happened due to failure in the update of SSL with time.

However, when it comes to TLS, there are several checks made. With an aim to enhance security, it added a lot of support for the new cryptographic algorithms. That’s why its most recent version (TLS 1.2) is the most secure compared to other services. Thus, one must update to the latest QuickBooks Desktop update for TLS 1.2 to keep your system stable and more secure.
