To enable TLS 1.2 by default, it is possible to install. NET 4.0 does not enable TLS 1.2 by default. Not compatible with TLS 1.1 or higher encryption NET use version 4.5+ and for Java use version 7u25+.Īctions required for integrating using. Please download the latest version from our support portal here.įor applications integrating with PPO, all API connections will require TLS 1.2. The Microsoft Project add-in for PPO has been updated to support TLS1.2. If you are not using one of these browser versions or newer, you will need to update to at least one of these versions. To continue to use PPO, you will need a modern browser, such as Microsoft Edge 12+, Mozilla Firefox 27+, Google Chrome 30+ or Apple Safari 7+. TLS1.1 only accounts for 0.005% of the traffic. How widely used are older versions of TLS in PPO?Ībout 97% of the traffic to PPO uses TLS1.2, and 3% uses TLS1.0. In 2006 TLS1.1 was launched in order protect against vulnerabilities seen in version 1.0, however, it was leapfrogged by TLS1.2 which was released two years later in 2008 and it’s rare to see TLS1.1 used. This implies that TLS1.0 does not keep the connection sufficiently secure. For several years now it has been known to be vulnerable to attacks such as BEAST and POODLE (although these have been mitigated in other ways), in addition to using weak cryptography algorithms. TLS1.0 was released in 1999, making it a nearly two-decade-old protocol. This is because the browsers may be vulnerable to downgrade attacks (which force users onto weaker versions of TLS to exploit known vulnerabilities). The continued support of TLS1.0 (& TLS1.1) poses a security risk. TLS1.2 is the latest version and by far the most secure of the three versions. There are currently three versions of the TLS protocol in use: TLS1.0, 1.1 and 1.2. Transport Layer Security (TLS) is a cryptographic technology protocol used to provide communications security over computer networks. To continue to use PPO, you will need to upgrade to a more modern browser which supports TLS 1.2.įor applications integrating with PPO, all API connections will also require TLS 1.2. As a result, users attempting to connect to PPO using unsupported browser versions will be unable to do so. we will no longer allow traffic for these protocols) and will be discontinued as of 31 July 2018. Support for TLS versions 1.0 and 1.1 is being deprecated (i.e. Very old browsers may however still use TLS 1.0 or TLS 1.1 which are no longer considered to be secure. Most modern browsers use TLS 1.2 which is considered secure. and Transport Layer Security (TLS) is used to encrypt these connections. PPO users use HTTPS to connect to their instances of PPO, i.e.
