"Wow, woods, can you get me another sniper suit, what's left? Let's get dressed! "Pig Yes, the thought came and went, and his eyes were starry, looking at the sea of fire, and the attributes of the Starlight Flying Shoes were indeed very attractive. Looking at the last golden card, everyone knew that the rest of the card was the special attribute item that the system said. "Buzz!" The last gold card bloomed in Qin Feng's hand, and a purple ground triangle gem appeared in front of Qin Feng and the others.

Purple Gem: One of the missing parts of the Devil's Kiss. The short introduction made Qin Feng like a pig thinking about it, and his eyes were full of stars and saliva flowed down. "Vomit my God! I love you guys to death! "The demonic kiss in Qin Feng's hand is mutilated, everyone knows it, and now that he has obtained this gem in this situation, can it not be surprising!" Haha maple! Congratulations! When everyone saw the last item, they congratulated Qin Feng one after another, they didn't feel sorry for not getting their own things, because this gem was very important to Qin Feng.

"Oops! It's seven o'clock, it's time for breakfast. The sea of flames looked at the real time in excitement, "Kaede, are you really going to play in the final round of this team competition?" "Well, if there are no accidents. It's not going to be easy for you to get to the finals! Qin Feng didn't want to waste time on the boring preliminary competition, because he didn't want to skip school again for the sake of a preliminary competition, after all, he was still in school, of course, he focused on studying.

"Hey, hey! I must have been handsome that time! By then, MM won't be a big deal! "Pig Yes, I thought about it, and it seemed that I blamed Qin Feng for all the reasons why I couldn't be in the limelight...... After a moment of small talk, everyone quit the dream.

"Denial-of-service attacks are one of the oldest and most common forms of attack. Strictly speaking, a denial-of-service attack is not a specific attack method, but the result of an attack, which ultimately makes the target system unable to continue to provide normal services due to some degree of damage, or even leads to physical paralysis or collapse. The specific methods of operation can be varied, it can be a single means, or a combination of multiple methods, and the result is the same, that is, legitimate users cannot access the information they need. Usually denial-of-service attacks can be divided into two types, Qin Feng, you can help the teacher answer which two types are they" On the podium of the multimedia classroom, Deng Zhongming looked at Qin Feng who was sitting in the first row with a smile.

"The first is to bring down a system or network. If an attacker sends some illegal data or packets, the system can crash or restart. Essentially, the attacker carried out a denial-of-service attack because no one was able to use the resource. From an attacker's point of view, the thrill of an attack is that it is possible to send only a small number of packets and make a system inaccessible. In most cases, the system comes back online requiring administrator intervention, rebooting, or shutting down the system. So this kind of attack is the most destructive, because doing a little bit can destroy it, while repairing it requires human intervention.

The second type of attack is to send a large amount of information to a system or network so that it cannot respond. For example, if a system cannot process 100 packets in a minute, but an attacker sends it 1,000 packets per minute, when a legitimate user wants to connect to the system, the user will not have access because the system is already running out of resources. To carry out this attack, the attacker must continuously send packets to the system. When the attacker does not send packets to the system, the attack stops and the system is back to normal. This method of attack requires a lot of effort for the attacker because he has to send data constantly. Sometimes, this attack can bring down the system, but in most cases, only a small amount of human intervention is required to restore the system. Both of these attacks can be carried out both locally and over the network. Under the gaze of the whole classroom, Qin Feng replied very fluently.

"Yes! The answer is very correct and can be given a full score. Well, that's the end of the lesson! Class. Deng Zhongming looked at the time, and then walked out of the multimedia teacher. After Deng Zhongming left the teacher, Qin Feng also followed the crowd to the outside of the teaching building.

Drizzle in mid-May. The sun was shining and falling, washing the air strangely cool. The leaves are still small, but there is some greenery everywhere. The shy spring sun only lightly, some soft light peeked out from the thin clouds, and the figures on the ground and the shadows of the trees seemed very faint. The wild peach blossoms bloomed the earliest, and the faint pink swayed in the wind and rain, like a charming little village girl, dressed simply and beautifully.

"Sea! Qin Feng, who are you waiting for! Qin Feng passed by with a good classmate, smiling slightly and revealing a row of white teeth. Hehe! Qin Feng smiled faintly and did not answer. At this moment, not far away, Li Qiuxue was wearing a purple tights and black denim shorts, and when she walked towards Qin Feng, her long flowing hair was flying in the air. "Kaede! Sorry I'm late! Just after class, I went to the following dormitory. Li Qiuxue stood opposite Qin Feng, and her unique fragrance was filled with the air.

"Hmmm! Every time, I just got out of class not long ago...... Hungry or not? Go out and eat! Qin Feng took a deep breath of the fragrance in the air, took out his mobile phone and looked at it, and the time was almost twelve o'clock. Hehe! You don't say I'm really a little hungry. Li Qiuxue touched the exposed little belly, and then touched the back of her head, and her eyes narrowed into a crescent moon. Let's go, little fool, I don't know you yet? Let's go to the old place! After speaking, Qin Feng took Li Qiuxue's hand, and walked towards a small restaurant outside the school gate under the envious eyes of a group of classmates.

Although it was time to eat, there were only a few people in the small restaurant. Qin Feng and the others only like this place because the boss here and Qin Feng are both from E City, and Qin Feng can let Li Qiuxue feel the taste of the following dishes from his hometown. It has been more than 1 month since the last time I saw Li Qiuxue in the library, and this month Qin Feng not only made Li Qiuxue's depressed mood gradually improve, but also deeply captured her heart.

After his grandmother's death, Li Qiuxue no longer had any financial resources. When Qin Feng took the initiative to help her, she refused three or four times, but she couldn't be as young as Qin Feng, in Qin Feng's words, "As your own woman, of course you have the obligation to support her!" ”

After dinner, the two stayed in the library until six o'clock in the afternoon before leaving, and every afternoon, Qin Feng had to practice on the back mountain for two hours before entering the dream. It was the same this time, after the two left the library, Qin Feng had just sent him downstairs to the girls' dormitory. "Dutu", a white BMW drove from not far away. The car stopped when it reached Qin Feng and the others, and a young man in a white suit who looked to be in his twenties walked out of the car. The man was about 1.8 meters tall, and his blue hair was slightly tilted back. Could he be the legendary Prince Charming? Well, no, because it's supposed to be the prince of BMW!

"Huh? Xiaoxue, who is he? Prince BMW looked at Qin Feng with slanted eyes, and his tone was full of disdain. What Qin Feng hates most is this kind of self-righteous person. "Where did you come from?" Qin Feng called tooth for tooth, and his tone was even more contemptuous than that of Prince BMW. "You...... Xiaoxue told me who he was! The BMW prince trembled with anger, and pointed his finger at the tip of Qin Feng's nose. He's my boyfriend! Li Qiuxue's faint answer made the BMW prince even more crazy. I don't care about you! Qin Feng saw that Prince Baoma's finger was pointing at him, which was a very impolite performance, Qin Feng just slapped his hand away in Li Qiuxue's face, if it was someone else, his finger would have fallen to the ground in the next second.

"Light snow! Tell me and I'll give you whatever you want! But how can you do this, do you know how much I like you? The BMW prince almost lost his mind, shaking Li Qiuxue's shoulders vigorously with both hands, what made him particularly unhappy was that since Li Qiuxue fell in love with such an ordinary boy, didn't he have a handsome face compared to himself, and what else was better than himself.

Qin Feng next to him had a very ugly face, Li Qiuxue told herself that there had always been such a number one person pursuing her, but she didn't expect that this BMW prince would completely treat herself as non-existent. "Touch" Qin Feng knocked the BMW prince to the ground with a gentle kick, this kick was indeed very light for Qin Feng. At this time, the prince of BMW had a fierce face and slowly got up from the ground. "Humph! We'll see! There was a cold killing intent in the eyes of the BMW prince.

After watching Prince Charming leave, Li Qiuxue set her eyes on Qin Feng, "Feng be careful, this person is very small, and his father is the president of a large company in City A. Looking at the look in his eyes when he left just now, I don't think this matter will be just like that! There was a hint of worry in her obvious tone, after all, for Li Qiuxue, Qin Feng was the most important person in her life now, and Li Qiuxue didn't know that Qin Feng had a stunt at this time. Snow, you can rest assured about this! By the way, if he dares to harass you, tell me, I have to kill him! "There are a few people who can not be angry when they joke that their girlfriend is harassed by others.
