the weapon, so this axe has 36 law also. Reasons for election: In the 2005, the development of information security technology will show obvious polarization trend: the road of integration and specificity of the road. In the security requirements are not too high in the industry, such as school network, and gradually tend to some comprehensive, Taibaodalan comprehensive security products; Another single-minded is also a trend, such as firewalls, IDS and network management products will be more
cause more serious consequences on a system than on other systems. It is necessary to test various situations in the image production environment, not just forecasts, and re-test after changing any part of the infrastructure. 3. Build Load Balancing for the infrastructure Once the critical point is identified, the next step should be to establish Load Balancing for the infrastructure, with the goal of optimizing communication flows under normal and peak loads. 4. Considering the scalability
, resulting in a denial of service (denial Service). This is a very smart distributed Denial-of-service attack (distributed denial of service) Unlike a typical distributed Denial-of-service attack, the attacker does not need to look for a large number of dummy machines, and the proxy server acts as the role. Then, the computer room used hardware firewall can be a good defense against DDoS attacks? To study
a clever Distributed Denial of Service attack (Distributed Denial of Service). Unlike a typical Distributed Denial of Service attack, attackers do not need to look for a large number of bots, the proxy server acts as the proxy server. So can the hardware firewalls used by the data center defend against DDOS attacks? To solve this problem, we should first look at the ha

In particular, for some large enterprises, their main businesses are accumulated in servers. If the servers are attacked, the loss of important information or con
DDoS (Distributed denial of service) attack is a simple and fatal network attack using TCP/IP protocol vulnerability, because the TCP/IP protocol is unable to modify the session mechanism, so it lacks a direct and effective defense method. A large number of examples prove that the use of traditional equipment passive defense is basically futile, and the existing firewall equipment will be paralyzed due to limited processing capacity, become a network

Traffic reinjection: After cleaning by the abnormal traffic cleaning guard device, normal access traffic is injected into the original network to access the destination IP address. From the perspective of protected hosts, there is no DDoS attack and the service returns to normal. Du

Although it is not completely defensive against DDoS attacks, under certain conditions, it is still the pressure to slow down the Apache (httpd) server. If you work with iptables, har
