Wireless network systems can cause serious security problems if they do not take appropriate security measures, whether the wireless system is installed at home or in the office. In fact, some providers of Internet services for residential areas have banned users and other unauthorized people from sharing networking services in their service agreements. An insecu

How can we deploy the emerging wireless network technology? How can we improve network security? Here is a detailed introduction. 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

First, the preface My experience tells me: Information security is a kind of artificial confrontation against information protection, it is the competition between man and man in technology and thinking, and it is the war of real "no smoke". The way of attack is multi-faceted and multi-level, so it is a complicated project to establish an effective information security guarantee system, it is a "war" becau

The firewall consists of 4 parts of service access policy, verification tool, packet filtering and application gateway, which is a software or hardware between the computer and the network to which it is connected (in which the hardware firewall is rarely used only by the Ministry of Defense, because it is expensive). All network traffic that is flowing into and out of the computer passes through this firew

With the rapid popularization of Internet applications, the relationship between people and networks has become increasingly close. However, due to the openness and interconnectivity of the Internet, there are many insecure factors in the network, malicious software attacks, and hacking behavior seriously threaten people's interests and security. Therefore, we need a solution that can protect computers agai

We know that the WEB server can be divided into three layers, and any layer of the server may cause security threats to the entire website. Therefore, when deploying a WEB server security policy, enterprise security management personnel should comprehensively build an Enterprise Web security protection

The primary factor for promoting IPv6 network protocols is the failure of IP addresses. However, at present, the Internet is in an excessive phase of Two-Protocol handover, which leads to an important problem-security. In this unstable situation, security vulnerabilities may easily occur. How can we prevent them?First, let's take a look at some basic knowledge ab

Define the appropriate permissions for the user to complete related tasks Users with administrator permissions can also execute activities that disrupt the system. For example: · Accidental changes to the system reduce the overall level of network security. · If you are cheated and run malware, the latter will use the user's management permissions to achieve their ulterior motives. · Causes information lea

In the war, a line of defense without depth will collapse after a single point of breakthrough. However, when multiple lines of defense are built, the lack of timely and intelligent coordination between lines of defense may compromise the attack defense efficiency. Because the soldiers in various defense lines fight independently, they cannot organize effective counterattack after a line of defense is broken, Network

Financial service providers are restricted by a large number of customers' data security protection rules. Gramm-leaching-Bliley Act (GLBA Act) is widely used and abstract, but it requires risk identification and evaluation for all types of networks, implement and monitor security measures, including wireless networks. Other regulations, such as the famous Payment Card Industry Data

If college students do this, the customers of coffee shops do this, and your neighbors living in 3C apartments may also do the same. Many computer users search for accessible wireless networks in shopping malls, schools, homes, and other places, regardless of whether they are allowed to use these networks. Either intentionally or unintentionally, these wireless "parasites" do not simply steal signals. Once they connect to a wireless network, it is pos

Now everyone in the hands of mobile devices more and more, most of the home installed without lines from equipment to facilitate the mobile phone, tablet computer Internet. Some routers cover a larger area of the signal, even run to someone else's home, this time to be careful to rub the net. In the Tencent computer Butler, there is a function called "Wireless Security Assistant", this function can help users to detect all the use of

The switch occupies an important position in the enterprise network, which is usually the core of the whole network. In this era of hacker intrusion and virus-ridden network, as the core of the switch is also taken for granted a part of the responsibility of network security

Linux network security skills-network intrusion check The log file in the operating system is an important clue for detecting network intrusion. Of course, this assumes that your logfile is not damaged by the intruders, if you have a server that uses a leased line to connect directly to the Internet, this means that yo

Wireless networks are more vulnerable to intrusion than wired networks, because the computers at the attacked end do not need to be connected to the computers at the attacked end, attackers can access your internal network and access resources as long as they are within the valid range of a wireless router or repeater in your domain.
