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

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

1. Lan Layer Many preventive measures can be taken on the LAN layer. For example, although it is almost impossible to completely eliminate the counterfeiting of IP groups, the network management can build a filter. If the data carries the source address of the Intranet, it can effectively reduce the internal counterfeit IP attacks by limiting the data input traffic. Filters can also restrict external IP group streams to prevent DoS attacks from fake I

The development environment of a company is usually deployed on the Intranet, and then there will be public servers for developers and tests. Therefore, there is often a need to connect to the server through ssh or a local mysql client, in my personal experience, companies often encounter slow ssh/mysql connection to public servers. This is because ssh and mysql services use reverse DNS resolution at login by default, the

Port, the same network virus. Generally, the destination IP port is the same. For example, the port of the shock wave virus is 135, and the port of the shock wave virus is 445, as long as these ports are restricted on the vro, the external virus will not be able to access the Intranet through the unique entry of the Internet cafe router. packets initiated by internal network viruses, due to restrictions on Internet cafe routers, vrouters can reduce t

is said that gsecdump can capture the HASH of DC, but I think this will also beIf MACFELL is killed, you will not try again. I was too easy to learn. I really couldn't think of other methods.Exit the Remote Desktop and take a bath. While washing and thinking, I suddenly remembered that the 3389 login record was installed yesterday. After cleaning out, check the record and check that the system administrator of the local machine has logged on. Another user has logged on to this machine,The logon

. Managers must adopt a two-factor real-name authentication mechanism with higher security to separate "persons" from "devices" and bind them one by one, only the corresponding "person" can use the corresponding "device" to complete identity authentication. This ensures the legitimacy of the devices connected to the network, enhances the controllability of the internal network, and facilitates the Administrator's unified management of the network. 3) scientific and strict system security check B
