Assess Web-based settings for Web-based device access: HTTPS redirect, Web encryption strength,

phone home, Web file printing, Go button, Cancel button and Continue button.

Web Encryption Settings

For encrypted Web-based communication with the HP Embedded Web Server (EWS), the encryption

strength and individual protocols can be set. Select the check box to assess these settings. This will not

enable or disable encrypted Web-based communication. Some web encryptions use identity

certificates in the device. Consider installing trusted identity certificates before enabling.

After Microsoft announced insecurities with SSL3.0, it has been disabled by default in a Security

Manager policy. It can be enabled if desired, but it will display a warning reminding you on the

vulnerabilities exposed by using it.

Note: If FIPS 140 is enabled, Web encryption strength is set to High and SSL 3.0 is disabled.

SSL = Secure Sockets Layer

TLS = Transport Layer Security (follow-on to SSL … 1.0, 1.1, 1.2)

TLS v1.0 is marginally more secure than SSL v3.0, its predecessor. However, subsequent versions of

TLS — v1.1 and v1.2 are significantly more secure and fix many vulnerabilities present in SSL v3.0

and TLS v1.0. The newer TLS versions, if properly configured, provide many stronger ciphers and

encryption methods.

Require HTTPS Redirect

When HTTPS redirect is enabled, accessing the device via a Web page is redirected through a

secure port (HTTPS). HTTPS uses identity certificates in the device. Consider installing CA signed

certificates before enabling.
