Network security products have their own merits

The topic of network security has been put on the agenda of enterprises in recent years. Even so, it occupies an important position in the overall security of enterprises. Because enterprise network security involves all aspects of the enterprise network, there are products such as firewall, intrusion detection (IDS), anti-virus, and network vulnerability scanning. This causes enterprises to be confused when selecting network security products, because different products have different prices and different security requirements between enterprises, how to get the most benefits at the lowest cost and find the most cost-effective product portfolio has become a challenge for enterprise network security construction. Below we will introduce several types of security products, hoping to help you.

For the moment, if we compare an enterprise to a house, how can we protect our house is the network security construction of the Enterprise.

First, we will think of building a high wall outside the house. In the enterprise network security, this high wall is like a firewall. Firewalls Use Network Access Control Technology to set up control measures for internal networks and insecure network boundaries of an organization to prevent unauthorized access to internal network information resources, at the same time, you can also use a firewall to prevent important enterprise information from being illegally exported from the company's network. by limiting the communication with the network or a specific area, you can prevent illegal users from intruding into the network. Firewall is a passive defense technology. Because it assumes the boundaries and services of the network, it is difficult to control illegal internal access. It is like using a high wall to enclose the house, however, there is no way to deal with illegal access and attacks within the high wall. Therefore, firewalls are suitable for relatively independent networks and a single network with concentrated network services.

Real-time Monitoring products are also known as intrusion detection products. The so-called intrusion detection is to collect and analyze information from several key points in a computer network or computer system, to detect whether the network or system is in violation of security policies or is being attacked by hackers or viruses. Real-time Monitoring is mainly accomplished through the following activities: Monitoring and analyzing user and system activities; monitoring of system configurations and known system vulnerabilities and vulnerabilities; identifies activities that are in line with known attack patterns, conducts statistical analysis on abnormal activity patterns, evaluates the integrity of important systems and data files, and tracks and manages operating systems, and identifies users' violations of security policies. There are also some real-time monitoring software that can automatically install the patch software provided by the vendor and automatically record information about intruders. However, some real-time monitoring products that access threat access through normal channels cannot trigger alarms. Real-time Monitoring is mainly used to monitor the entire system, which is similar to the role of the guard dog in the yard. To detect exceptions, you need to report them to the master so that you can know whether the visitor is a hacker or a thief, or something is blown down by a strong wind. Therefore, the real-time monitoring product can monitor and collect abnormal information. However, anti-virus and other products are required to solve the problem after the problem is found.

Anti-Virus products can be divided into two categories: hardware and software, such as anti-virus gateway and anti-virus software. Generally, anti-virus gateways are installed between two or more networks. They detect viruses and worms on the edge of the network. Generally, they are installed between the Intranet, external network, and public network, or install it between the network of the organization and the network of the external partner. The gateway works deeply at the application layer to quickly monitor data streams flowing through any direction of the Gateway in real time. If a virus is detected, the gateway intercepts and clears the virus logs and submits reports to the Administrator, then, the virus-free data stream is forwarded to the destination. Anti-virus software is a software product that specifically detects viruses hidden in networks or systems or programs with security threats, it can only work when a virus has been detected and causes losses.

The network vulnerability scan system is a product that checks vulnerabilities in the running network system and provides corresponding solutions before a network security event occurs. RJ-iTop-based network vulnerability scanning system focuses on the period of time before a security accident occurs. By simulating hacker attacks, the system performs security vulnerability and hidden danger scanning, submit the risk assessment report and provide corresponding rectification measures, which is most suitable for regular and irregular preventive security checks, and can expose the security risks in the network to the maximum extent. Whether hackers or viruses intrude into the system, the most important thing is to take advantage of security vulnerabilities in the network system. data shows that the newly discovered security vulnerabilities increase exponentially every year, intruders often launch attacks before enterprises discover security vulnerabilities. In this case, intruders and enterprises are playing a speed war. If enterprises can use hidden danger scanning tools to discover vulnerabilities in the network system, and take appropriate measures to resolve viruses. The vulnerability library of the RJ-iTop network vulnerability scan system of the banyan software is fully based on the international CVE standards. enterprises can upgrade the vulnerability library to keep up with the latest international standard through local or network upgrades, the number of vulnerability updates provided by the software is 5-10 on average every week.

It can be seen that although there are a wide variety of network security products, they are comprehensively considered based on the product features and the level of security requirements of enterprises, the key data center and the system center involving trade secrets are treated differently. Combining the advantages of each product, we can build a cost-effective network security barrier.
