Many of my friends know the bucket theory. The maximum capacity of a bucket is determined not by its highest capacity, but by its lowest capacity. The same is true for servers, the security of a server is also determined by its most vulnerable aspect. The most vulnerable aspect is how dangerous a server is. The same is true for

For readers: DDoS researcher, major webmaster, network administratorPre-Knowledge: ASP Basic reading abilityMany friends know the barrel theory, the maximum capacity of a bucket of water is not determined by its highest place, but by its lowest place, the server is the same, the security of the server is determined by its weakest point, and the most vulnerable places are more dangerous than the server.

There are two main types of DDoS attacks: Traffic attacks, which are mainly attacks against network bandwidth, that is, a large number of Attack Packets Cause network bandwidth to be blocked, legitimate network packets are flooded with false attack packets and cannot reach the master. The other is resource depletion attacks, which are mainly attacks against server hosts, that is, the host memory is exhausted or the CPU is used up by the kernel and app
DDoS (Distributed Denial of Service) has made another huge step forward in DOS development, this Distributed Denial-of-Service attack allows hackers to use different high-bandwidth hosts (hundreds or even thousands of hosts) that have been intruded and controlled) install a large number of DOS service programs on them, waiting for commands from the central attack Control Center. The central attack Control Center then promptly starts the DOS service pr
DDoS is the abbreviation for "Distribution denial of service" in English, which means "distributed Denial-of-service attack".
This attack method uses the same method as an ordinary denial of service attack, but the source of the attack is multiple. Typically, an attacker uses a downloaded tool to penetrate an unprotected host, and after obtaining the appropriate access rights for that host, the attacker installs the software's services or processes (

The basis for successfully mitigating DDoS attacks includes: knowing what to monitor, monitoring these signs around the clock, identifying and mitigating DDoS attacks with technology and capabilities, and allowing legal communication to reach the destination, real-time skills and experience in solving problems. The best practices discussed below reflect these pri
Detailed explanation on how vro is configured to implement DDoS defense and detailed explanation on router ddos DefenseWhat are the operations on vro settings to implement DDoS defense? First, we need to understand what the principles of DDoS attacks are before we take anti-
DDoS deflate is actually a shell script that uses Netstat and iptables tools to block IP that has too many links, effectively preventing common malicious scanners, but it is not really an effective DDoS defense tool.
Work Process Description:
The same IP link to the number of connections to the server after the setting of the cut value, all over the cut value of the IP will be masked, while the shielding
DDoS attacks are essentially time-series data, and the data characteristics of t+1 moments are strongly correlated with T-moments, so it is necessary to use HMM or CRF for detection! --and a sentence of the word segmentation algorithm CRF no difference!Note: Traditional DDoS detection is directly based on the IP data sent traffic to identify, through the hardware firewall. Big data scenarios are done for sl
high-profile, good reputation products. And then, if there is a special relationship or agreement with the network provider, it is better, when a large number of attacks occur, it is very effective to ask them to make a traffic limit at the network point to fight against certain kinds of DDoS attacks.2, try to avoid the use of NATWhether it is a router or a hardware protection wall device to avoid the use of Network address translation NAT, because t
or targeted use of scanners to discover the internet on those vulnerable machines, such as program Overflow vulnerability, CGI, Unicode, FTP, database vulnerabilities ... (Almost endless AH), are the scan results that hackers want to see. Then is the attempt to invade, the specific means is not here to say more, interested in the words on the internet there are many articles about these content.In short, hackers now occupy a puppet machine! And then what
rooms, commercial sites, game servers, and chat networks have been plagued by DDoS attacks for a long time, as a result, customer complaints, confusions with VM users, legal disputes, and business losses are a series of issues. Therefore, solving DDoS attacks becomes a top priority for network service providers. 2. What is
Preface
As in the real world, the Internet is full of intrigue. Website DDoS attacks have become the biggest headache for webmasters. In the absence of hardware protection, finding a software alternative is the most direct method. For example, iptables is used, but iptables cannot be automatically blocked and can only be manually shielded. Today we are talking about a software that can automatically block the IP address of
Ddos-deflate is a very small tool for defense and mitigation of DDoS attacks, which can be tracked by monitoring netstat to create IP address information for a large number of Internet connections, by blocking or blocking these very IP addresses via APF or iptables.We can use the Netstat command to view the status of the current system connection and whether it is compromised by a
Before we look at this issue, let's talk about what DDoS is:
What is DDoS:
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
Considerations and testing methods for DDOS Security Products in the Internet cloud ecosystem (I)The three elements of DDOS attack security are "confidentiality", "integrity", and "availability". DOS (Denial of Service) targets "availability" of services ". This attack method exploits the network service functional defects of the target system or directly consumes system resources (mainly network resources)
