intranet redesign

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

To protect Intranet security, I believe that firewall programs are installed on the Intranet of the vast majority of organizations. As a result, the idea of many network administrators attempting to remotely control the Intranet workstation on the internet is forcibly "contained. This is not the case. Because my local network is installed with a firewall and only

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) ...

Add to Using Command 2 Route Add-p Network Address mask Subnet Mask gateway address You can add a route that you add to your path in a permanent route (also known as a static route) Use the command effect chart as follows: Delete Using Command 3 Rotue Delete network Address You can delete a route In general, the system will automatically add a static route to all the networ

Apt Local source build (can be used for LAN Apt-get source or local source) This document describes the use of Apt-mirror software to build apt local source requirements: Intranet development environment for its specific reasons can not Sisu network, So we need the local intranet source to make it easy for developers to download and install software recommendations: Use a single disk to store source files o

Because the company in the computer room hosting server IP is not enough, but also for security considerations, so that a number of virtual nodes can not directly access the Internet, so I xenserver physical nodes through the use of iptables NAT function made a simple implementation [Root@xenserver-cukxsegi ~]# sysctl net.ipv4.ip_forward=1 #开启转发[Root@xenserver-cukxsegi ~]# Echo ' net.ipv4.ip_forward=1 ' >>/etc/sysctl.conf #让重启不失效[Root@xenserver-cukxsegi ~]# iptables-p FORWARD DROP #将FORWARD链的策略

Intranet address port is the LAN MSSQL address port, the network address port customization.(2) After the mapping succeeds, the external network access connection MSSQL uses the mapped extranet address domain name port.

A simple introduction of squid Through Squid Proxy server to achieve intranet users to share the Internet, configure Squid cache and basic access control to accelerate and restrict access to Web services. For web users, squid is a high-performance proxy caching server that speeds up the intranet browsing the Internet and increases the client's access hit rate. Squid not only supports HTTP protocol, but al

Objective:Sometimes we want to access the local area network SQL Server server, such as test environment database in the company intranet, back home or at the customer site to connect to the database in the intranetThe first step: if you can connect to the local area network database 192.168.150.129, remote also can connect itThe second step: Add a TCP port in the intranet pangolin, the IP of the local IP,

As an omnidirectional Security Network Technology in Intranet security, it uses a flexible key management solution to implement secure network communication between any two computer terminals in an open network. 1. Overview of omnidirectional Security Network Technology Omni Directional Secure Network (ODSN) is a patented technology applied by Ming Dynasty Wanda. Omnidirectional security network technology uses flexible key management solutions to eff

The idea of Intranet penetration is derived from the idea of Trojan horse-bastion hosts are the easiest way to break through from the inside. A large website, a large company, a large target, and an external target, administrators will always do everything they can to strengthen prevention and fix vulnerabilities. It is almost impossible to use conventional methods. The breakthrough of Intranet penetration

I once saw an article on the Internet that introduced a method for direct access to the Intranet. In fact, we only need to use the port ing tool to easily penetrate the Intranet. Port er is a tool like this. It is even more worth mentioning that it breaks away from the command line mode and provides a graphic interface operating environment. I. Basic Ideas To help you better understand the principle, let me

Article 1 1. Set a gateway in the attributes of one network card (for example, you can set one of the two Intranet segments and one Intranet for the convenience of setting up the Internet). Leave the other gateway blank first. 2. Run cmd. Run the "route-p add Intranet CIDR Block mask subnet mask Intranet Gateway (lef
