6 Secure Copy TABLE 16 Protocol SSH SSL Secure protocol support Description Secure Shell (SSH) is a network protocol that allows data to be exchanged over a secure channel between two computers. Encryption provides confidentiality and integrity of data. SSH uses public-key cryptography to authenticate the remote computer and allow the remote computer to authenticate the user, if necessary. Fabric OS uses secure socket layer (SSL) to support HTTPS. A certificate must be generated and installed on each switch to enable SSL. Supports SSLv3, 128-bit encryption by default. Table 17 describes additional software or certificates that you must obtain to deploy secure protocols. TABLE 17 Items needed to deploy secure protocols Protocol Host side Switch side SSHv2 HTTPS Secure shell client None No requirement on host side Switch IP certificate for SSL except a browser that supports HTTPS SCP SSH daemon, SCP server None SNMPv1, SNMPv2, SNMPv3 None None The security protocols are designed with the four main use cases described in Table 18. TABLE 18 Main security scenarios Fabric Management interfaces Comments Nonsecure Nonsecure Secure Nonsecure Secure Secure Secure Nonsecure No special setup is needed to use Telnet or HTTP. Secure protocols may be used. An SSL switch certificate must be installed if HTTPS is used. Switches running earlier Fabric OS versions can be part of the secure fabric, but they do not support secure management. Secure management protocols must be configured for each participating switch. Nonsecure protocols may be disabled on nonparticipating switches. If SSL is used, then certificates must be installed. For more information on installing certificates, refer to "Installing a switch certificate" on page 111. You must use SSH because Telnet is not allowed with some features. Secure Copy The secure copy protocol (SCP) runs on port 22. It encrypts data during transfer, thereby avoiding packet sniffers that attempt to extract useful information during data transfer. SCP relies on SSH to provide authentication and security. 104 Fabric OS Administrator's Guide 53-1001336-01
