network isolation switch

the whole network of MAC address information can be learned, the two-tier switch is to build and Maintain its own Address table. The following three points can be inferred from the working principle of the two-layer switch: (1) because the switch to the majority of port data exchange, this requires a very wide exc

subnet consists of several network segments, through the combination of switch ports, you can logically divide the subnet. Broadcast messages can only be broadcast in the subnet, can not spread to other subnets, through a reasonable division of the logical subnet, to control the purpose of broadcasting. Because a logical subnet is any combination of switch ports

Analysis of physical isolation function and realization technology Positioning of the physical isolation network GateInstead of replacing firewalls, intrusion detection, vulnerability scans, and antivirus systems, the physical isolation technology is another cornerstone of the user's "defense-in-depth" Security strat

The first model of isolation:Both Guest1 and Guest2 are virtual machines.First of all, to understand that the virtual machine in Linux network card contains the first half and the second half, the first half of the virtual machine, the second half on the host, here CENTOS6 for example,Eth0 for the GUEST1 virtual Machine network card, corresponding to the second half of the vnet0, on Guest1 all the data sent

Original address Background information The default network connectivity policy for security groups is that the network is interoperable between instances within the same security group, and the default intranet is disconnected between instances of different security groups. This strategy meets the needs of the vast majority of customers, but a few customers want to change the security Group

At present, many organizations are planning and considering more security issues at the beginning of network construction. The uncommon security measure is to isolate the network, the so-called network isolation is the concept of "getting out", either getting out of the enterprise intranet, or getting out of the enterp

In Windows8, we have introduced a new WinRT platform, bringing to users modern Apps with dynamic tiles and immersive user experiences, if you are an enterprise user, have a company's proxy server environment, or you are a developer, I believe you have discovered that after a local connection to a replacement agent, all Modern Apps are no longer able to access the network. This is due to the network

In Windows 8, we have introduced a new WinRT platform that gives users modern Apps with dynamic tiles and immersive user experiences. If you are an enterprise user, have a company's proxy server environment, or you are a developer, believe you have found that all modern Apps are no longer able to access the network after a local connection replacement agent. This is due to the network

interruption, the system supports setting off-line policy and time limit; Under normal policy permissions, users can use security domain and quarantine data off-line normally, but prohibit unauthorized export and network outbound, the system will record the operation log and audit in detail. 　　7. Data Security Outgoing When important documents in the security domain need to be sent out, need to submit a clear or secret text outside the application,

changes the MAC address, you need to change the access list rules. Otherwise, the rules will not work properly. In addition, in some cases, communication between PCs is not allowed, but all PCs are allowed to communicate with a server or gateway. The topology shows: The above functions can be implemented using MAC address-based access control, but the operations are cumbersome. In this case, we can use a private VLAN to implement the above functions: 1. Place the

I. Requirements for information security According to the technical requirements of information confidentiality, the secret-involved network can not be directly connected with the Internet, and if the secret-related network is connected with the non-dense network, if the network is not physically isolated from the Int

from Eth2.10, discovers that the destination address is 172.16.20.11, and looks at its own routing table:The packet is then forwarded from the eth2.20.③ through the ARP record information, the router can know 172.16.20.11 on the host2, so the data packets sent to HOST2.④HOST2 data is packets to BBOX4 based on destination address and VLAN information.The connectivity and isolation of the Macvlan network rel

The specific methods are as follows: 1. Open the Local Group Policy Editor, and then, on the local Group Policy Editor, expand Computer Configuration-Administrative Templates-Network, and then open network isolation; 2, and then on the WIN8 system to find the "Applied Internet Proxy Server" to find the specified Internet agent, you can see the desktop IE
