It is also important to note that the spread of worms can lead to a large number of domain name resolution requests.3.7.2 UDP DNS Query flood protection?The UDP DNS Query Flood attack is protected on the basis of UDP Flood?Reduce server load (using DNS Cache) by proactively responding to domain name IP self-learning resultsBandwidth throttling for source IP
The old boy was busy recently because he wanted to train students and correct his homework. He had to write books and videos frequently. He had a bad idea. He was invited by a friend to participate in a forum, after a while, I would like to share some of my thoughts on DDOS attacks. If you are interested in in-depth discussions, contact me. Okay, enable the following:1. To defend against DDOS attacks, you m
To defend against DDoS is a systematic project, the attack pattern is many, the defense cost is high bottleneck, the defense is passive and helpless. DDoS is characterized by distributed, targeted bandwidth and service attacks, which are four-layer traffic attacks and seven-layer application attacks, corresponding to t
