Firewalls and switches are still commonly used. So I studied how firewalls and switches implement Intranet/Internet isolation. Here I will share with you, hoping to help you. With the maturity and rapid development of network and Internet technologies, more and more enterprises and institutions have begun to set up networks to automate office work and share Internet information. However, security issues have also emerged. iMaxNetworks (memory network

as input. Note that the this documentation, referring to an IP address as an IPv4 address or an IPV6 address was a semantic property O f the address, not just the length of the byte slice:a 16-byte slice can still is an IPv4 address. Type IP []byte func IPv4 Func IPv4 (A, B, C, D byte) IP IPV4 returns the IP address (in 16-byte form) of the IPV4 address a.b.c.d. Donuts, see the documentation for more details: https://golang.org/pkg/net What is an

Author: chenling roseIntranet, many people should have formed this concept. Many external websites or servers on large networks are not necessarily useful. Of course, Internet is also a breakthrough. Most of the time, we start with the Internet. As security continues to reinforce, it has become increasingly difficult. So how do hackers usually perform Intranet penetration and how does Intranet penetration c

The problem is that there are two existing machines: intranet: one server on the intranet, which cannot be accessed directly from the Internet. Internet: the internet can access files and servers on the machine. At the same time, the machine can access any files on the intranet .. Due to historical reasons: the problem above the

threat outbreaks in the LAN. Relying on a single border firewall and anti-virus software, it cannot cope with viruses and other information security threats. Only by protecting each client can it effectively prevent virus intrusion, information leakage, and worms, network abuse and other problems. Therefore, Enterprise Intranet security management becomes increasingly important. Overview of Intranet Securi

as we all know, in order to infiltrate the intranet, you have to be in that intranet. But when you install Kali in VMware, most users do not choose bridging mode for convenience, but instead choose to use IP networks shared with nativeof course, this will be able to surf the Internet, but your virtual machine does not actually get the intranet IP. If you do not i

network, then basic NAT is responsible for translating the subnet IP of the node into a globally unique IP and sending it out. (Basic NAT changes the original IP address in the IP packet, but does not change the port in the IP packet). For basic NAT, refer to RFC 1631.Another kind of NAT is called NAPT, which we can see from the name.Napt not only changes the IP address of the IP datagram that passes through this NAT device, but also changes the TCP/UDP port of the IP datagram. Basic NAT Device

After writing object 672, a critical problem of the software is exposed. If both the server and client are in the Intranet environment, that is, both parties use NAT to access the Internet, in this case, the client cannot directly communicate with the server. The solution can be: 1: deploy the server in a public network without Nat. 2: Use common Nat penetration methods, such as UDP injection or STUN Protocol. However, these methods require another kn

Environment: Cent OS 7.0 background: The title of this article can be set as follows because he is the same workaround:(1) Why Dubbo automatically use the intranet IP when registering zookepper.(2) Dubbo Consumers cannot connect to the service provided by the producer(3) ... Scene Restore 1. Project Deployment Framework Recently in the development of a project, the use of the Dubbo service, the following is the case of project deployment, The details

stop spoofing, the target computer will not be able to access the network normally, resulting in user O M accidents. To sum up, there are many problems with ARP spoofing blocking methods. Therefore, Intranet security products should use this method dialectically. 1. Avoid being single and adopt multiple blocking methods The Intranet security risk management and audit system connects terminals to vswitches

A man's martial arts: the idea of Intranet penetration testing (2) Web penetration (previous article)Http://www.bkjia.com/Article/201412/357403.htmlDifferent, Intranet penetration requires more randomness and breakthrough, and the situation is more complicated. When encountering obstacles, sometimes you can use different ideas to break through. In many cases, you can only stop here. Here are some of my summ

How to use Linux bots to penetrate a small Intranet The shell method in the case is relatively simple. We only focus on the limited space, starting from obtaining permissions.Install BackdoorAfter entering the system, my RP was so lucky that it turned out to be the root permission...View passwd account informationDirectory tree structure:Because Intranet penetration is required and permissions may be lost a

Today to tell you how to use the port mapping, not through the Gateway Open intranet method. First: The use of the premise Need to have a public network of IP. If we now have a public network of ip:210.210.21.21 II: Tools to use 1.lcx.exe 2.vdic Three: Method explanation Method One: Use Lcx.exe to map. (1) We will upload the Lcx.exe to the public network IP, in the public IP on the DOS environment in the implementation of Lcx–listen Port 1 Por
