This was later broken down creating A1a and A1b. It consisted of servers like ADAM, WSUS, DNS, middleware, application SMTP relays, etc. These applications would cause security issues if in DMZ-W1. While the PIX had access to the DMZ-W2 it was restricted to tunnels from specific vendors ending at the Cisco ASA.ĭMZ-A1 was for applications related to DMZ-W1. All vendor-based LAN to LAN VPN tunnels went through the Cisco ASA VPN device. All the basic HTTP servers plugged into this DMZ.ĭMZ-W2 was the VPN solutions. This is where the Coyote load balancer was located as well. The Cisco PIX was the main entry for internet customers DMZ-W1 and vendor access DMZ-W2 as well as External applications communications DMZ-A1a.ĭMZ-W1 was the home of the front most customer facing web servers. That was all they did some routing as all firewalls. The second layer of defense was split between Cisco PIX and later a Juniper Networks device. It connected to our network via a copper to the PIX. I figure it is safe now 20 some years later. I was never required to tell the auditors what it was and never did. It had penetration testers asking us what it was for years. Extensive ACL's and security configuration made it a downright bulletproof solution. I locked it down tights as I possibly could. It was a layer 4 switch from Extreme Networks that was specifically designed to be an external facing BGP router. Two for Customer access, one for employee VPN access and one for management of the external facing solution. Then it when from there.įorward most facing Layer 1 devices were fiber optic Ethernet switches running BGP. It all got very complicated:ĭesigned then partially managed the implementation and support of multiple working DMZ's. Starting with the PIX 509 that was upgraded to a 520. It was difficult to explain you can't do something that they are already doing. It was different back then people were put in charge of or allowed to do stuff they didn't understand. So those computers could use the internet. At one point people used to just put public IP's on computers inside the networks. Maybe you could talk them into a proxy device, but defiantly not a firewall. You had to configure a router or put a box and configure IPChains. In the beginning you could not talk a company into purchasing a firewall. ASUS OptiMem technology carefully maps memory signal pathways across different PCB layers to reduce vias and adds shielding zones that significantly reduce crosstalk.Here's the deal. Revisions to the motherboard’s trace routing provide the latest Intel processors with unrestricted access to memory bandwidth. ASUS B560 motherboards provide all the fundamentals to boost daily productivity, so your system will be ready for action with stable power, intuitive cooling and flexible transfer options. Prime B560 series is built to handle the additional cores and increased bandwidth of 11th Generation Intel ® Core™ processors. The heatsink is held in place by captive screws and can be moved to other M.2 slot. M.2 HeatsinkĪn M.2 heatsink takes care of the two M.2 slots, warding off throttling that can occur with M.2 storage during sustained transfers. The Prime B560 motherboard packs flexible tools to tune every aspect of your system, enabling performance tweaks to perfectly match the way you work, to maximize productivity. Tune It Your WayĬomprehensive controls form the foundation of the ASUS Prime series. Boasting a robust power design, comprehensive cooling solutions and intelligent tuning options, PRIME B560-PLUS provides daily users and DIY PC builders a range of performance tuning options via intuitive software and firmware features.
