the user authentication and authorization of port-based access control. 1. Client. Generally installed on the user's workstation, when users have access to the Internet needs, activate the client program, enter the necessary username and password, the client program will send a connection request. 2. Certification System. In the Ethernet system to authenticate the switch, its main role is to complete the user authentication information upload, release work, and according to the results of the
application interfaces and protocols. It is well known that the lower-level structure provides a broad set of important services: socket and connection management, request and response processing, various security policies, caching and many more enforcement measures. Whenever you initialize an HTTP request or XMLHttpRequest, a persistent service push event or WebSocket session or open a WebRTC connection,
hardware token generation part, and the latter is the user identity and token pass code. Other verification solutions involve transferring security certificates within the Secure Shell SSH) or IPSec. Disable unnecessary services It is a good thing to have a large number of routing services, but many recent security ev
Computer popularization, broadband prevalence, now many friends online time is very long, so the security of the system has become "the most important." Fortunately, many security sites now provide online detection services, can be a good help us to detect the existence of their own computer vulnerabilities and security
specific mode and set the threshold value of data packet capacity from one or more sources within a specific period of time. These switches can then discard the data packet or redirect it to another destination using other technologies and protocols. Most routers and other network platforms do not have such a detailed control mechanism. 2. Attacks against specific applications and services: these attacks o
who want to enter the network. In a business network, because of the need to sacrifice security to enable this feature to meet the frequently changing wireless access, the network member is relatively fixed as a home wireless network, so it is not necessary to turn on this

passes through a sensitive network segment, some rules such as pci dss will fully ensure the security of users. You can reduce risks by Dividing Traffic to reduce exposure. Specifically, the firewall is used to check data packets to prevent data packets from entering the CIDR block that can be accessed without corresponding permissions, it also implements the logging function of time series synchronization
A common feature of Server Load balancer, SoBig, blster, and other worms is to attack system vulnerabilities, resulting in large-scale network interruptions. Even though the patches that blocked them had been released before the outbreak of these viruses, the spread of the virus still could not be effectively restrained, mainly because the patch system was ineffective.There are two reasons for the difficulty in repairing the system: first, from the di
