DDoS is a shorthand for distributed denial-of-ser

We know that the VPS server is a virtualization technology, build VPS server virtualization software and new cloud architecture solutions are many, they have advantages and disadvantages, therefore, different VPS Server service providers may use different virtualization technology to build VPS servers, Similarly, the c

First look at the VPS is what: plain English is that it is from a physical server divided into multiple ' virtual ' server, has its own independent public network IP, independent memory, independent CPU, independent operating system configuration, independent hard disk space, etc., can be convenient to restart the server alone, its own installation program, Like a smaller version of the physical server, use it to do multiple virtual hosting, Enterpris

How to solve the problems of switch DDoS attacks and Intranet server DDoS attacks Those who have experience in Internet cafes or data center management must know that computer viruses are a headache, especially intranet server DDoS attacks and switch DDoS attacks, which directly affect the security of Internet cafes,

1. Common DDos attack types SYN Flood: it is currently the most popular DoS (DoS attacks) and is a type of TCP connection request that uses TCP protocol defects to send a large number of forged TCP connection requests, so that the attacked party's resources are exhausted (the CPU is full or the memory is insufficient. Smurf: This attack sends a packet with a specific request (such as an ICMP Response Request) to a subnet broadcast address, and disguis

To go to the bank to do business examples:Network layer DDoS is to let the road to the bank become congested, unable to get the people who really want to go to the bank, often use the protocol as a network layer, such as TCP (using three handshake response to wait and limit the number of computer TCP connections), etc.The application layer DDoS is to consume the bank's business resources, such as using HTTP

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

VPS Exclusive host has been small and medium enterprises and high-end webmaster users of the best choice to build a station, and, with the cloud computing technology application and development, the VPS host prices more civilians, making more people contact with VPS host, and often use VPS host. At the same time,

define a bad IP? Indicate that below. NO_OF_CONNECTIONS = 150 // The maximum number of connections. IP addresses exceeding this value will be blocked. Generally, the default value is enough. ##### APF_BAN = 1 (Make sure your APL version is atleast 0.96) ##### APF_BAN = 0 (Uses iptables for banning ips instead of APT) APF_BAN = 1 // whether to use the public IP address whitelist or iptables. We recommend that you use iptables to change the value of APF_BAN to 0. ##### KILL = 0 (Bad IPs are 'nt

If you think that the virtual host cannot meet your needs, want more resources, and feel that the whole machine is a waste, the VPs server may also be suitable for you. In terms of price, the VPs host is between the virtual host and the host lease. The performance of the website is more stable than that of the virtual host. users on the VPs do not compete for
