Each layer of communication has its own unique security problems. Communication connections at the second protocol layer of the data link layer are relatively weak in terms of security. Network security issues should be addressed at multiple protocol layers for different vulnerabilities. In this article, we will focus
The definition of a security zone plays a vital role in establishing a secure network. The DMZ (demilitarized Zone) is the most important partitioning term in network security. Because the DMZ contains device properties, it separates it from other parts of the network. These
1th. HTTPS Network security Access Service 1.1 issues related to network security ①. Network security issues-data confidentiality issuesTransmitted data may be visible to third parties at all times②.
(1) Major network security threats The reliable operation of the network system is based on the communication subnet, computer hardware and operating system and various application software and other aspects, all levels of good operation. As a result, its risk will come from threats to the various key points of the enterprise that may result in the failure of th
With the development of technology, the number of technical problems also increases. For wireless networks, improving or improving the security of networks also brings inevitable problems. Here we will introduce them in detail. The extensive use of wireless networks also brings about the security of wireless networks. Because wireless networks are different from wired n
It is usually easier for hackers to launch attacks by exploiting vro vulnerabilities. Vro attacks waste CPU cycles, mislead information traffic, and paralyze the network. A good router uses a good security mechanism to protect itself, but this is far from enough. To protect the security of a router, the network adminis
For network security, this is a more complex structure and engineering. Many factors can affect our network environment. In the network, we define various network security protocols for effective protection. Next we will compare a
Many of us are familiar with the development of wireless network technology. We will introduce how to deploy wireless networks in detail here. Due to business needs, enterprises have higher and higher mobile requirements, and security risks also emerge. Although a solution has been developed to solve specific security problems, we also need to adopt a comprehensi
Log data can be a valuable information treasure or a valuable data quagmire. To protect and improve your network security, log data of various operating systems, applications, devices, and security products can help you discover and avoid disasters in advance, and find the root cause of the security event. Of course, t
This article is intended not to tell everyone how to perform intrusion, but to remind everyone that "intrusion is accidental, but security is not inevitable ", do not neglect some of the operational details.I have always had the habit of visiting Security websites on a regular basis. Recently, I came to a famous network secur
A computer network is an open, free, interconnected, and shared platform. It is the most important carrier in the information storage, dissemination, and use process of modern society. It enhances the flexibility and convenience of information circulation, at the same time, it poses a huge challenge to the security of sensitive information. The fight against cyber password theft and anti-password theft has
There are a lot of Wireless Configuration technologies in enterprises, so some network administrators are not very clear about the specific methods to improve network security. Here we will explain in detail. The current enterprise network not only has a fixed line LAN, but also has a wireless LAN. In fact, both wired
World Wide Web, such as transaction payments2. HistoryNetscape created HTTPS in 1994 and was used in the Netscape Navigator browser. Initially, HTTPS was used with SSL, and when SSL evolved to TLS, the latest HTTPS was formally determined by RFC 2818, which was released in May 2000.It is developed by Netscape and built into its browser to encrypt and decrypt data and return results that are sent back on the network. HTTPS actually applies the Netscap
Security first is the premise for us to do anything. At the same time, we also need to ensure the safe operation of the network when using routing. Here we will analyze how to configure the router, makes the network more secure. A router is an important bridge between a LAN and an external network. It is an indispensab
the 802.11G based wireless router price of around 200, 11g wireless network card in 150 yuan, compared to 11n products are 11g product price 7-8 times. Although the 11N product technology leader, but because the price and the technology is immature and so on factor we do not recommend the small and medium-sized enterprise to use, compared with 11g's product is more suitable for the small and medium-sized enterprise use.
SummaryNessus is a powerful and easy-to-use remote security scanner that is free and extremely fast to update. The security scanner performs security checks on a specified network to identify whether the network has a security vul
In terms of networks, especially wireless networks, security issues are very important. Now, let's take a look at the wireless network security issues. We hope that you can learn more about this. If the wireless network system does not take appropriate security measures, whe
In traditional IPv4 networks, security has always been a headache. Now the IPv6 protocol network has solved many security problems for us. This is because, in the IPv4 network, the evolved version V6 adopts different transmission structures, so the security mechanism has cha
The security of WLAN wireless networks is defined in the following four levels: 1. Spread Spectrum and frequency hopping wireless transmission technology make it difficult for the hacker to capture useful data;2. Set strict user passwords and authentication measures to prevent illegal user intrusion;3. Set up an additional third-party Data Encryption solution, which is hard to understand even if the signal is stolen.4. Adopt
Zhoulian Summary: With the development of network technology, network information system has gradually deepened to all walks of life, network security has become a topic of concern, an organization's information systems often face the risk of internal and external threats, if you do not have a certain hacker technology
