. If the TCP serial number of the target system can be pre-calculated, whether the Blind TCP three-time handshakes with pseudo source address can be inserted or not is worth testing! In fact, the experiment I did does not explain anything. I just verified the TCP protocol serial number and the test and calculation functions. I think the author is inspired by the CC attack principle and cannot figure out the proxy method to achieve the CC attack effect. However, it is not feasible to tell the tru

DOS and DDoS attacks and Prevention

. Second, Distributed Denial of Service attacks are even more difficult to prevent. Because the Distributed Denial-of-Service attack data streams come from many sources and attack tools use the random IP technology, the similarity with valid access data streams is increased, making it more difficult to judge and prevent attacks. Attack policy and Prevention At present, with the wide spread of various DDoS attack tools such as TFN, TFN2k, Stacheldra

1. Defensive base 1.1. How big is the attack flow?When it comes to DDoS defense, the first thing to do is to know how much of an attack has been hit. The problem seems simple, but in fact there are a lot of unknown details in it. In the case of SYN Flood, in order to increase the efficiency of sending SYN wait queues on the server, the IP header and TCP header are not populated with optional fields when the attack

Can the hardware firewall of the engine room be able to prevent DDoS?

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 a direct and effective defense method.

Distributed denial of service attack (DDoS) principles

There are many kinds of Dos attacks, the most fundamental Dos attacks are using a reasonable service request to occupy too much service resources, so that legitimate users can not get the service echo. DDoS assault is a kind of invading method which occurs on the basis of traditional Dos attacks. Single Dos attacks are usually a one-to-one approach, when the approach to the principle of low CPU speed, small memory, or small network bandwidth and so o

Can the hardware firewall in the IDC defend against DDOS attacks?

Before studying this issue, let's talk about DDOS: What is DDOS: DDoS (Distributed Denial of Service) attacks are simple and fatal network attacks by exploiting TCP/IP protocol vulnerabilities. Due to the session mechanism vulnerabilities of TCP/IP protocol, therefore, there is no direct and effective defense means. A large number of instances prove that the use

initiates a 100,000 request (SYN) to an open port on the server, and itself refuses to send a SYN-ACK response, the server's TCB will soon exceed the load, in addition, attackers can forge the source IP address in the packet so that the attacker will not be blocked by the packet returned by the server. It can be seen that this is a serious problem in the TCP/IP protocol. Data packets are filtered through firewall policy audit to prevent DDOS attacks
