2011年5月9日 · You separate the DMZ from the rest of the network both in terms of IP routing and security policy. You identify your network areas. Internal: critical systems; DMZ: systems you can afford to be "exposed", systems you want to host services to the outside world, e.g. your SSH hosts; External: the rest of the world.

That DMZ switch seems like it should be untagged. I don't think there is any need for an additional switch for your DMZ, unless you have size and configuration concerns. If it's a small scale network, as I envision, you should be set with the small DMZ on-a-stick configuration. Many small business all-in-one type appliances have a very similar ...

2012年4月19日 · My past designs are more complext than a front and back FW. In an extremely highly secured ISP/DMZ design, I architected FW, IPS, front VIP network, DMZ VIP Load Balancers, Private Farm networks, then the back-end Internal Facing FWs. Each of these layers adds a unique additional barrier to entry for the hacker to get through.

2022年10月21日 · So the connection is initiated from the LAN to the DMZ. The SMTP server in the DMZ only answers to the LAN server. I read some topics here and found that this is commonly admitted as a tolerable exception of the "no DMZ to LAN flow". I understand that only ONE stream, from DMZ to ONE asset in the LAN on ONE TCP port only is a low risk.

2013年2月10日 · Give it a DMZ NIC and a Trusted Net NIC. Make sure your database security is locked down and everything is blocked in and out except the traffic you want (i.e. allow AD traffic on the trusted NIC and not on the DMZ, etc.) That would give you, logically, the topology you described, but it will increase the risk if your database server is ...

2014年6月30日 · Microsoft released an article about putting domain controllers in the DMZ which proves an interesting read. Many believe that many internet-facing proprietary MS products can be exposed the internet with minimal risk (such as Exchange) which is why they discontinued TMG, however you'll need to address the requirements for a DC in the DMZ in ...

2024年11月9日 · Reverse Proxy@DMZ -> API Gateway@DMZ -> App@Internal -> (Data Access Service@Internal) -> DB@Internal. Basically, API gateways are simple applications with few dependencies, and thus offering a much smaller attack surface that the main app. Whether a data access service is needed is questionable.

2019年7月12日 · I was thinking on setting up an additional router, DMZ its static IP, and from my personal router, open ...

2016年11月23日 · Multiple Firewalls are definitely better than one. I use three. Behind the first is the DMZ with "honey pot" which monitors traffic, has the Email Proxy, Browser Proxy, and the Internet servers; all SE Linux. Honey Pot information helps in creating the Black List for the second firewall.

Talking about features, a DMZ is a hole between networks. Normally it provides a way to expose an internal service to the Internet. While not technically part of the NAT definition, it's a feature of all modern NATs. NAT is firewall and in some situations, the best one. Stateful inspection firewalls, which don't do NAT, do mostly "fail-open".
