ApsaraVideo Live provides the Transport Layer Security (TLS) version control feature to ensure data security and integrity for Internet services and communications. You can configure TLS versions based on domain names. This topic describes how to configure TLS versions.
TLS is designed to ensure the security and integrity of data transmitted between two applications. HTTPS is a typical application of TLS. HTTPS, also known as HTTP over TLS, is a secure version of HTTP. HTTPS runs below the top application layer (HTTP) and above the transport layer (TCP), and provides data encryption and decryption services.
- Log on to the ApsaraVideo Live console.
- In the left-side navigation pane, click Domains to go to the Domain Management page.
- Find the streaming domain or ingest domain that you want to configure and click Domain Settings.
- In the TLS Version Control section, you can enable or disable specific TLS versions as needed. Note If the HTTPS certificate is not configured, the TLS Version Control section is not displayed.The following table describes TLS versions.
TLS version Description Supported browser TLSV1.0 TLSV1.0 was defined in RFC 2246 in 1999 as an update to SSL 3.0. TLS 1.0 is vulnerable to various attacks, such as BEAST and POODLE attacks. TLS 1.0 can no longer protect network connections due to the low encryption performance. TLS 1.0 does not comply with Payment Card Industry Data Security Standard (PCI DSS).
- Chrome 1+
- Firefox 2+
TLSV1.1 TLSV1.1 was defined in RFC 4346 in 2006 as an update to TLS 1.0. TLS 1.1 fixed some vulnerabilities of TLS 1.0.
- IE 11+
- Chrome 22+
- Firefox 24+
- Safari 7+
TLSV1.2 TLSV1.2 was defined in RFC 5246 in 2008 and is a widely used TLS version.
- IE 11+
- Chrome 30+
- Firefox 27+
- Safari 7+
TLSV1.3 TLSV1.3 was defined in RFC 8446 in 2018. TLS 1.3 is the latest TLS version. TLS 1.3 supports the zero round trip time resumption (0-RTT) mode and allows you to establish faster connections. TLS 1.3 supports only key exchange algorithms of perfect forward secrecy to improve security.
Note By default, TLSV1.0, TLSV1.1, and TLSV1.2 are enabled.
