238 Connecting across multiple platforms Securing CrossPlatform connections ■ Connecting to a serialized host Encrypting your CrossPlatform sessions Encryption is a method of encoding or scrambling data to prevent unauthorized users from reading or tampering with the data. Symantec pcAnywhere CrossPlatform uses encryption to ensure that the data that you send cannot be read or altered by unauthorized users while in transit. If the host and the remote are running pcAnywhere 11.5 or later and the encryption levels do not match, pcAnywhere automatically raises the encryption level on the computer that is using the lower level to match the encryption level on the computer that is using the higher level. If you are using symmetric encryption, pcAnywhere also raises the algorithm levels if the one of the computers is using a lower level. For example, if the host encryption level is configured for pcAnywhere encoding and the remote encryption level is configured for symmetric encryption, pcAnywhere automatically raises the encryption level on the host to symmetric. If either the host computer or the remote computer is running pcAnywhere 11.0.x or earlier and the encryption levels or algorithms do not match, pcAnywhere attempts to lower the encryption level on the computer that is using the higher level to match the encryption level on the computer that is using the lower level. You can configure pcAnywhere to deny the connection instead. To encrypt your CrossPlatform sessions 1 In the pcAnywhere CrossPlatform Session Manager window, on the File menu, click Connect. 2 In the pcAnywhere CrossPlatform window, click Advanced. 3 In the Advanced Options window, under Encryption, in the Level list, select one of the following: ■ None ■ pcAnywhere encoding ■ Symmetric 4 In the Algorithm list, select one of the following: ■ RC4 ■ AES This option is only available if you select symmetric encryption.
