In order to use SYN? Cookies to calculate the SYN-ACK serial number (that is, SYN? Cookies), the host must first combine some local password bits, a data structure including IP address and TCP port number, SYN initial sequence number, and some index data identifying the password bits. An MD5 digest is generated on top of all the above bytes, and then some bits are truncated from the hash value to put it into the SYN-ACK sequence number. Since the size of the sequence number is about a quarter of the total hash value, this truncation is necessary, but usually at least 3 bytes of hash bits are used for verification, which means that there are still nearly 2 24 possibilities to guess and verify cookies without knowing the password bits. In order to send out the hash value, some bits of cookies will reduce the upper limit value of MSS (Maximum Segment Length) contained in SYN and affect the index bits that identify the native password bits in the hash value.
According to statistics, SYN attack is the most common and easily used attack method among all hacker attacks. I believe many people still remember the attack on YAHOO website in 2000. At that time, hackers used simple and effective SYN attacks. Some network worms cooperated with SYN attacks to cause greater damage. This paper introduces the basic principle, tools and detection methods of SYN attack, and comprehensively discusses the prevention technology of SYN attack.

Not only did I hear the voice, Almost half of the entire position 149 heard it, Then the position was bombed, The soldiers all took up their weapons and held the horses and bees in the air desperately to "hug the fire" (note: meaning to pull the trigger and fire), Even if there are some comrades who did not hear the cry of "fight", When they saw others firing, they followed suit. Those big wasps are abundant, Flying densely and bulky, So when we started shooting, The shooting rate is quite high, After the sound of the gun became one, it gradually became equal to the "buzzing" sound. No one can beat anyone, It feels strange that the two sounds are mixed together. Now that I think about it, It's like a rock band playing "heavy metal" (here "heavy metal" is a genre of rock music, Before the 1970s, This rock style is called 'hard rock', It was later renamed 'heavy metal', Of course, this is one of the more well-recognized explanations about the origin of the "heavy metal" genre of rock music. There are several other different explanations, As it is not relevant to this article, It will not be discussed in detail here), Then they gathered fire and shot for more than ten seconds. The left and right sides of the position were covered with the smashed bodies of this big wasp like rain. But then the bullets hit them more and more scattered in the air, finally forming a "circle", covering the whole position under, and then one by one dive to the ground, although they scattered, but in this way their distribution area is wider, and the spacing is widened, not as dense as before, plus flying fast,
In the future, if I have the opportunity, I will continue to participate in the social practice activities of "three rural areas" to serve the rural economic development and social progress in our province. Make contributions to the prosperity of the motherland.
