DA-Desk no longer supports user systems and client systems that are not compliant with the Transport Layer Security (TLS) 1.2 protocol. If you continue to use older versions of TLS, you could potentially lose access to all DA-Desk products and services.
What can I do to resume the service?
Modern web browsers support TLS 1.2 and 1.3. Upgrading your browser can enable you to access these apps and services. You can download and install one of the following popular browsers:
If you’re using another browser, ensure that it supports TLS 1.2.
Transport Layer Security (TLS) is a security protocol that provides privacy and data integrity between two communicating applications. It is deployed widely for web browsers and other applications that require data to be securely exchanged over a network.
According to the protocol specification, TLS includes two layers, the TLS Record protocol and the TLS Handshake protocol. The Record protocol provides connection security. The Handshake protocol enables the server and client to authenticate each other and negotiate encryption algorithms and cryptographic keys before data exchange.
DA-Desk has security compliance standards that require disabling support for older protocols. One such standard ensures compliance with the Payment Card Industry (PCI). PCI adaptation server is a set of security standards require organizations that accept, process, store, or transmit credit card information to maintain a secure environment.
PCI compliance mandates the use of TLS 1.2.
