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.

Nonsecure protocols may be disabled on nonparticipating switches. If SSL is used, then certificates must be installed.

Secure Copy

Table 17
describes additional software or certificates that you must obtain to deploy secure
protocols.
The security protocols are designed with the four main use cases described in
Table 18
.
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.
SSH
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.
SSL
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.
