User Guide Browser security Browser security About TLS The BlackBerry® Browser configuration is designed to use TLS or SSL to encrypt data that your device sends or receives over the Internet through the BlackBerry® Enterprise Server. Communication between your device and the BlackBerry Enterprise Server is encrypted using Triple DES. Communication between the BlackBerry Enterprise Server and content servers is encrypted using SSL or TLS. To increase security, you can set up TLS for HTTP connections between your device and the BlackBerry Enterprise Server and use Triple DES encryption for all other communication between your device and the BlackBerry Enterprise Server. About WTLS The WAP Browser configuration is designed to use WTLS to encrypt data that your BlackBerry® device sends and receives over the Internet through a WAP gateway. Communication between your device and the WAP gateway is encrypted using WTLS. Communication between the WAP gateway and content servers is encrypted using TLS or SSL. Manage browser security 1. In the device options, click Security Options. 2. Click TLS or WTLS. 3. Set the security options. 4. Press the Menu key. 5. Click Save. TLS options TLS Default: Specify the type of TLS or SSL connection that your browser uses for HTTP connections. To use a direct TLS or SSL connection, change this field to Handheld. To use Triple DES and TLS or SSL, change this field to Proxy. Allow HTTPS Redirections: Specify whether a prompt appears before a secure web page redirects your browser to another web page. Protocol: Specify the protocol that your BlackBerry® device uses for TLS connections between the browser and content servers. Encryption Strength: Specify whether your browser only accepts and sends data that is encrypted using 128-bit encryption. To accept and send only data that is encrypted using 128-bit encryption, change this field to Strong Only. To accept and send data that is encrypted using 128bit encryption or 56-bit encryption, change this field to Allow Weak. Allow FIPS Algorithms Only: 105
