Browser/SSH Client Compatibility

Minimum Requirements

With the factory default settings (equivalent to a factory reset), the device security setting (policy = None) favors interoperability, but may restrict access to certain Web browsers and SSH clients.
Before beginning the hardening procedure, you should make sure that you are able to configure your SSH client to be compatible with the following:

  • Version: SSH2
  • KeyExchange: diffie-helmann-group14-sha1
  • PublicKey: RSA 2048 bits
  • Cipher: AES-128-CTR
  • HMAC: HMAC-SHA2-256

Browser Compatibility with Cipher Suites

Before making a hardened device available to network users, you should verify browser compatibility (TLS 1.0 to TLS 1.2) with the following (minimal) list of cipher suites, assuming an RSA certificate is used:


Supported Browsers
