I have a symantec 5620 (build 3.0.1) gateway and the admin interface is a little sporadic. &nbsp;I can log in fine but lately it is consistently refusing to display the firewall rules and sometimes also the network interfaces. &nbsp;Most of the options in the left hand side of the navigation tree load just fine but the ones I want in particular, ie. Interfaces and Firewall Rules just won't display.<br />

The firewall itself is running fine and processing traffic, I need to make some changes is all! &nbsp;Anyone had a similar experience?

Symantec Gateway 5620 - Admin Interface problem

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

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
