Wireless LAN security issues have always been a top concern. So today we will also talk about this. Check whether network grade problems affect the security of the wireless LAN. Connect to the residential broadband network in a wi

First, what is needed on the network boundary People in order to solve the sharing of resources to establish a network, but the world's computer really linked to the network, security has become a problem, because on the

Abstract: With the development of computer networks, it brings resources sharing to people. At the same time, there are great security risks in data security. The TCP/IP protocol is widely used for communication in today's networks. This article analyzes computer network security issues based on TCP/IP communication pr

, each computer network operating system has a background management system, therefore, it is difficult to control the security risks of computer network operating systems. The computer network is designed to be an open and large-span environment with distributed control, re

I. The concept of a firewall In recent years, with the increasing number of ordinary computer users, the word "firewall" is no longer the agency of the server domain, most home users know to install a variety of "firewall" software for their own love machine. However, not all users are aware of the "firewall", some users even think that "firewall" is a name of th

the external network structure. Microsoft recommends this method because it fits into the deep protection security model. Note: there is an increasing trend: the internal network is divided into multiple security areas to create peripherals for each security area. Microsoft

Regarding the Security protection of Cloud computing data centers, CSA (Cloud Security Alliance, Cloud Security Alliance) put forward a total of eight suggestions in D7 of the Cloud computing key field construction guide, four security risks related to

organization's limited business bandwidth, which also leads to inefficient network applications. So, how to bypass these Internet abuses, fully enjoy the Internet to the organization to bring convenience and efficiency, so as to create a full range of safe and efficient Internet environment? Here are 8 ways to give you an answer. I. Promotion of border defense Firewalls, IDS, IPS are the basic devices f

The development of wireless networks is quite mature, but for our wireless network users, we will give a detailed introduction to how to set various wireless network security problems. As the prices of low-end wireless network devices continue to decline and the operation be

Security Settings for home networks are a key issue for us to study. Here we will introduce several tips to help us solve the security problems of wireless networks. Nowadays, most households access the Internet by setting up wireless networks. However, many people know that many network

the CSRF attack. CSRF Prompt By-Pass In Title input: 5229 In message input: The following results are obtained: Answers to questions after the experiment(1) SQL injection attack principle, how to defendPrinciple:利用现有应用程序，将恶意的SQL命令注入到后台数据库引擎执行的能力。通过在Web表单中输入恶意SQL语句得到一个存在安全漏洞的网站上的数据库，最终达到欺骗服务器执行恶意的SQL命令。Defense:以SQL注入为例,可以通过JAVA中的绑定变量等方法进行预防,JAVA的绑定变量方法是吧用户的输入作为一种变量,对SQL语句进行预编译,这样在执行时就不是顺序执行,而是把输入作为一种变量进行处理,不会在运行时进行动态的拼接SQL语句,防止了恶意的攻击代码被写入SQL语句进行解析和执行。(2) The

With the increasing risk coefficient of network security, firewalls, once the most important security defense means, cannot meet people's requirements for network security. As a supplement to firewalls and their benefits, IDS (Int

So speculate that there is

emergency response1. Security FunctionsEmergency response can cover the entire cycle.Emergency functions are often seen as scaling the PDR (protection, detection, and response) model to "recovery" in the PDRR (protection, detection, response, and recovery) model ". In fact, if we look at it from the complete system of business continuity management, emergency work covers the entire functional domain like the PDR model. From the initial preparation ph

With the increasing of the risk coefficient of network security, the firewall, which used to be the main security precaution, can not meet the need of the network security. As a useful complement to the firewall, IDS (Intrusion de
