How Do I Choose the Best Internet Security Software?

Network monitoring software refers to the monitoring and control of computers in a local area network; for the internal management of the Internet and internal behaviors and assets on a computer; process monitoring including online monitoring (monitoring and control of online behavior, security auditing of online behavior), and internal network monitoring (Intranet behavior monitoring, control, software and hardware asset management, data and information security);

Network monitoring software is a pointer

1. What is LAN network monitoring:

In order to give a complete definition of the LAN, two methods must be used: one is a functional definition and the other is a technical definition

(1) Functional definition: The LAN is defined as a group of desktop computers and other devices that are not far apart from each other at a physical address to interconnect users in a way that allows users to communicate and share computing resources such as printers and storage devices. System together. This definition applies to LANs used in office environments, LANs used in factories and research institutes.

(2) Technical definition: It is defined as a computer system interconnected by a specific type of transmission media (such as cables, optical cables and wireless media) and a network adapter (also known as a network card), and is monitored by the network operating system.

The difference between the functional and technical definitions is obvious. The functional definition emphasizes external behaviors and services; the technical definition emphasizes the material basis and composition methods required to form a LAN.

LAN monitoring

The widespread application of computer networks has penetrated into all levels of society, bringing convenience and social and security issues along with it. The Internet is a double-edged sword; for example, in the case of an enterprise, some employees use working time to watch news, play games, do private work, chat, leak company information, stock market, play movies, listen to songs, browse pornographic sites, Companies look for jobs while taking the boss's salary online. Not only consume company resources, but also because it affects the company's efficiency, leaks company secrets, and even loses customer resources is distressing. The use of LAN network monitoring software, a very effective management aid, combined with the company's internal management mechanism to achieve more results with less effort has become a consensus.

Many units are reluctant to invest in network and computer equipment, but they are not willing to invest in application software, especially security software. It is a waste of the company if a high-performance network is established and modern office equipment is purchased. Manpower and financial resources are even a problem for conniving employees to do things outside the unit during working hours; on the contrary, it reduces work efficiency and even leads to greater losses; therefore, network monitoring is very necessary;

The unit asked the network administrators and also built a website; but the equipment is well managed, but the convenience brought by the equipment reduces the work efficiency (all use the network to do other things), and the customers brought by the network because of lack of staff Management may become a competitor's customer directly; therefore, it is not enough to just buy equipment, it is not enough to just build a website, it is not enough to just manage the equipment, you also need to monitor the content of employees using the network and manage network behavior Up; especially foreign trade companies, high-tech companies (such as software, engineering), key government departments, etc. are of great significance to employees' online supervision and management. The overall goal of the network monitoring system is to effectively prevent employees from leaking information in various ways through the network, and to achieve unified management and effective monitoring of network computers and network resources. It is not allowed to send files in various ways without authorization, do not use the network to do things that should not be done, and be able to record the contents of network exchanges (such as the order process of foreign trade enterprises). Control, strict management and control of machine use, Internet access, email sending and receiving, online chat and computer games;

The network has entered our daily life, and the accompanying network security monitoring, network management, and employee network behavior have become increasingly prominent issues before us.According to the United States

1. LAN Internet monitoring software (Internet behavior management, network behavior audit, content monitoring, Internet behavior control)

It should include the following basic functions: monitor, record, and control the online behavior of other computers through any computer in the local area network; can achieve online monitoring, web browsing monitoring, mail monitoring, Webmail sending monitoring, chat monitoring, BT prohibition, traffic monitoring, up and down Line separation traffic bandwidth limit, number of concurrent connections,

Internet monitoring

There are two parts of network management in an enterprise. One part is to monitor the behavior and content of the Internet, that is, the Internet monitoring or external network monitoring. The other part is if the computer is not on the Internet but is on the internal LAN (such as printing). Files, etc.), generally called intranet monitoring or local network monitoring; online monitoring manages online content monitoring and online behavior monitoring (such as what emails are sent, whether to limit traffic, whether to allow QQ, or monitor users Page browsing); and the intranet monitoring and management is the local network activity process (such as whether there is COPY to the U disk, whether to play a stand-alone game, what to do with a computer, etc.).

The external network monitoring software mode can be basically divided into two categories: with client and without client (

Enterprise gateway unified management system

1) Integrated management gateway that integrates enterprise-level routers, firewalls, load balancing, flow control, Internet behavior management, DMZ zone server management, and dedicated line management.

2) Centralized management allows network administrators to comprehensively manage the network on one platform, reducing operation complexity.

Support deployment on win

Most servers in the enterprise use the windows operating system, and the product can share one server or PC of the enterprise with other programs, thereby reducing the cost of ownership of the enterprise.

Easy to install and operate

1) No need to check the user manual, non-network management personnel can also install, configure and use.

2) It adopts client mode, supports a large number of right-click and double-click functions, and the function association is intuitive and concise.

Accurate traffic analysis

1) Network application recognition rate is high, traffic statistics are accurate in real time, and truly reflect the network status.

2) The traffic display is very real-time, and the data is refreshed every 5 seconds, which is convenient for discovering network problems in time.

Significant flow control effect

The flow guarantee and speed limit are accurate, and the flow control effect is significantly higher than similar products.

Support intranet server

1) A comprehensive perspective of the overall traffic situation of the external network access server area from multiple perspectives;

2) Analyze the ratio of the bandwidth occupied by the Internet access server area and employees' Internet access and the characteristics of the traffic, provide a scientific data basis for bandwidth allocation, and intelligently and reasonably allocate both bandwidth.

3) More insight into the working status of each server in the server area, timely discovery of abnormally working servers, locating the attack source of the attacking server, and timely blocking of network attacks on the server.

Support multiple dedicated lines for centralized management

1) The group company has opened a number of dedicated lines for the headquarters and multiple branches. The enterprise needs to independently monitor and manage each dedicated line.

2) Support multiple virtual management systems in one system, each virtual system manages a dedicated line.

3) Manage 256 dedicated lines at the same time.

4) The management of each leased line is completely consistent with the management mode of the customer's total Internet export. It can perform real-time traffic analysis, leased line network quality analysis, historical traffic trend analysis, and leased line bandwidth management and control on each leased line.

5) It can greatly save the group customers' purchase costs, and also greatly reduce the complexity of the network administrator's management of the leased line, effectively guarantee the network quality of the leased line and improve the efficiency of the leased line.
