12: Security Settings The EDS device supports Secure Shell (SSH) and Secure Sockets Layer (SSL). SSH is a network protocol for securely accessing a remote device. SSH provides a secure, encrypted communication channel between two hosts over a network. It provides authentication and message integrity services. Secure Sockets Layer (SSL) is a protocol that manages data transmission security over the Internet. It uses digital certificates for authentication and cryptography against eavesdropping and tampering. It provides encryption and message integrity services. SSL is widely used for secure communication to a web server. SSL uses certificates and private keys. Note: The EDS supports SSLv3 and its successors, TLS1.0 and TLS1.1. An incoming SSlv2 connection attempt is answered with an SSlv3 response. If the initiator also supports SSLv3, SSLv3 handles the rest of the connection. This chapter contains the following sections:  SSH Server Host Keys  SSH Server Authorized Users  SSH Client Known Hosts  SSH Client Users  SSL Cipher Suites  SSL Certificates  SSL RSA or DSA  SSL Certificates and Private Keys  SSL Utilities  SSL Configuration SSH Settings SSH is a network protocol for securely accessing a remote device over an encrypted channel. This protocol manages the security of internet data transmission between two hosts over a network by providing encryption, authentication, and message integrity services. Two instances require configuration: when the EDS is the SSH server and when it is an SSH client. The SSH server is used by the CLI (Command Mode) and for tunneling in Accept Mode. The SSH client is for tunneling in Connect Mode. To configure the EDS as an SSH server, there are two requirements:  Defined Host Keys: both private and public keys are required. These keys are used for the Diffie-Hellman key exchange (used for the underlying encryption protocol).  Defined Users: these users are permitted to connect to the EDS SSH server. This page has four links at the top for viewing and changing SSH server host keys, SSH server authorized keys, SSH client known hosts, and SSH client users. EDS User Guide 93

SSH Settings
SSH is a network protocol for securely accessing a remote device over an encrypted channel. This
protocol manages the security of internet data transmission between two hosts over a network by
providing encryption, authentication, and message integrity services.
Two instances require configuration: when the EDS is the SSH server and when it is an SSH
client. The SSH server is used by the CLI (Command Mode) and for tunneling in Accept Mode.
The SSH client is for tunneling in Connect Mode.
To configure the EDS as an SSH server, there are two requirements:
Defined Host Keys:
both private and public keys are required. These keys are used for the
Diffie-Hellman key exchange (used for the underlying encryption protocol).
Defined Users:
these users are permitted to connect to the EDS SSH server.
This page has four links at the top for viewing and changing SSH server host keys, SSH server
authorized keys, SSH client known hosts, and SSH client users.
