I have a client with a SonicWall TZ205W. &nbsp;They have a test they have to run every month and until now it has passed every time. &nbsp;For some reason they are now getting a fail with the following message listed below. &nbsp;Not sure if this is a SonicWall problem or what needs to be done to fix this scan. &nbsp;Any help would be great before I have to put a trouble ticket in with Dell Sonicwall. &nbsp;Thanks!<br />

Synopsis :<br />
<br />
The remote host allows SSH connections with one or more Diffie-Hellman<br />
moduli less than or equal to 1024 bits.<br />
<br />
Description :<br />
<br />
The remote SSH server allows connections with one or more<br />
Diffie-Hellman moduli less than or equal to 1024 bits. Through<br />
cryptanalysis, a third party can find the shared secret in a short<br />
amount of time (depending on modulus size and attacker resources).<br />
This allows an attacker to recover the plaintext or potentially<br />
violate the integrity of connections.<br />
<br />
Solution :<br />
<br />
Reconfigure the service to use a unique Diffie-Hellman moduli of 2048<br />
bits or greater.

SonicWall SSH issue

Telnet is an application layer protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection. SSH was designed as a replacement for Telnet and for unsecured remote shell protocols. The term telnet is also used to refer to the software that implements the client part of the protocol. SSH provides a secure channel over an unsecured network in a client-server architecture, connecting an SSH client application with an SSH server.

SSH / Telnet Software

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

Network security consists of the policies adopted to prevent and monitor authorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, and covers a variety of computer networks; conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access.
