Security research process documentation

Security research process documentation

Originally completed in late September security research wanted to write, but it was a little excited there is no write, after being invited to do mentees experience sharing time, simply to write the full point.

The school security research places get

Professional CS: before the first six professional term 10% + CET-6 (> = 425) CET-4 (> = 550)

After the summer camp (usually beginning in April and lasts until early September), pre-free push early September, nine push 9.28

Camp is equivalent to pre-re-examination, but easier than some re-examination. Note that the machine test, the general hospital would arrange meter machine try. We will arrange seminars and mentors will meet up after the machine tried to contact the instructor in advance if you can interview and visit the laboratory.

Camp performed better (depending on the model test results) can be obtained excellent campers certificate (some schools have class distinction), security research with outstanding campers intends to direct admission certificate, postgraduate examination there are concessions.

Assessment content: generally test machine + English + Professional Interview Interview

Reference 1:

Moliu 211;
Rank: 6/75, CET-. 4 (436),. 6-CET (504), IELTS5.5 (L5.0-R6.0-W5.5-S4.5);
Main awards:
the ACM two Province and Shozo; scholarships; several other university;

Reference 2 (mainly forecasting name)

Reference 3

Since I was exam week period in July, and the vast majority of the school's summer camp held in time of conflict, as well as a few exams (such as Maogai) and summer camp crashed and led me to a summer camp (there were to get in Sichuan camp notice) did not go into, so I did not experience any Orz camp.
So the above basic school I reported to forecast name, and finally after a preliminary examination, only East, North Division and Zhongshan three, over the last only three. It is actually very bleak, far less than the other hand offer a variety of big brother.

NEU-free pre-push process (No. 9 September)

East pushed removed from our school is relatively easy, so no longer tired.

SYSU pre Push-free process (September 17)

The door, the staff checked identity cards and student ID, then the staff let me draw a topic from an envelope;

To sit down on the seat, there are five teachers, all male teacher, middle seat is facing the teacher;

Let me read something written on paper, I was able to get a few words about machine learning, mainly talking about the role of SVM support vector machine; After reading, you need to translate these words, so you can let the teacher 1 minutes, but the limited interview time, the need to pay attention;

After completion of the translation, the middle of the teacher asked me, "You had this scientific operating system now, you can talk about how to prevent a deadlock?"

I answered this is not very good, I am talking about is the requirement of a process can not occupy the time of the requested resource to other resources, or sort the processes that can not compete not seize resources and scientific resource consumption. In fact, this was wrong, and resources should be sorted, and then let the process in order to request resources.

But it feels really want to ask the teacher should avoid deadlock problems involving bankers algorithm that, I think the measures go;

The middle of a teacher I need to remind louder, this also needs to pay attention;

Then next to another teacher (also reminded me that the teacher) asked, "what programming language you used?", My answer C / C ++ used more, java learned but are not familiar with;

Then he asked, "C ++ how to achieve multi-state", I said the definition of virtual base class virtual function, the derived class overrides this function, run time will be based on the actual function call, in the middle also talked about specific code;

Other I did not know to ask is like a multi-state or multi-state function, but when I say virtual function, the teacher did not say anything, I'll be a polymorphic function;

Then he asked, "There is nothing between function overrides the relationship If the parameter is not the same Can??";

I mean the function name and return to the same values, parameters can also be transformed, for example, can be converted into double int and the like;

Continue to ask, "must be the same number of arguments it? Can different?"

I said no. Although the answer to, but here I actually thought to understand, to rewrite functions and overloaded function confused, overloaded function is actually possible, polymorphic function is a function of the same name is defined as a function of different parameters, but has been parameter conversion thinking went, say, like a number of parameters to be;

After the teacher, the leftmost a teacher asked, "What you have not done undergraduate research project?"

I was going to say their own written numeral recognition, but the fear of being asked to say did not do the reverse;

Then a teacher of the far right, "you played college ACM, computer-based test yesterday Why so bad?"

This simply did not have to quibble, 10 questions would have thought that we can have a 5-6 to no problem, the result of three simple questions stuck, then accidentally opened a little pit of simulation questions, the results after one, left under basic points it took only; not yet tried plurality Orz simulator.

After playing the game at that time I said, this thing has learned that security research, engage in security research to back it up, quite a long time did not do the topic, gave birth to a little hand, the teacher will let me. . . . . .

Then he asked, "Do you write on the graduate program is interested in computer graphics? What is your motivation?"

To be honest, at first I did not hear motivation, I heard behind vation, I was ignorant, what is vation, but combined with the previous question, the feeling is the motivation, just push it up;

I said at the top know almost have to see one author wrote the article, was used in what can only console output C characters, then can not be used as a graphical QT like to see the author of this article, this the author himself wrote a PNG function, again extend PNG image 1 * 1, the author says only 30 lines of code to draw a C-shaped Christmas tree or something, and then to the interested;

Because this is really seen, so that a little, Milo Yip is this man who wrote the article is very good;
after this or teacher, "You have done what preparation?"
Listen to the presentation, there are ignorant about, then or react, says it is prepared;
I say buy a book "Fundament of Computer Graphics", but because it is in English, more difficult to see, so only saw part of it.
I did read this book, and indeed it looked a little, but the original a little expensive, I see the electronic version;
the general flow is the case, would also like to ask the teacher, resulting in an alarm clock rang, it is over;
to be honest I did not notice there is an alarm clock next to come forward;
the final result, candidates.

BNU Pre Push-free process (September 26)

North Division pre-free push is on September 26, the schedule above, 8:00 to 8:30 reports, pay + sign + identity verification. Immediately after the start of the test machine and the English exam, both. On board a total of four questions, the first three channels are analog and greedy, attention to detail, such as int explosion and the like, the last one is the Tower of Hanoi problem, not written, in fact, should take recursion points to the lie.
26 pm professional knowledge written test and interview, both at the same time, do need to do is to pay out half of the interview prepared, I was feeling as people's voice is not particularly large (may disturb other people), so we ask a.
Written questions is a hybrid data structures, and computer architecture, the kinds of questions are multiple choice questions and word problems and algorithms.
The main structure of the test data are some basic manual operations, such as stack and out, to build the minimum spanning tree, maximum minimum heap heap building process, the critical path and so on, is not difficult;
comparative examination of the basic structure of a computer system, are an integral principle of multi-computer points, such as complement representation scope, but test a bizarre item about MIPS, although this is a last study section of the original title I've ever seen, but I will not to.
So at that time I only have done this other topics not when the heart is still very nervous, and this time I called to interview.
Interviews with six teachers sitting on a table, left three, there are three.
North Division teacher I've ever had the most amiable teacher, the beginning of a male teacher left some say in English, in fact, the effect is to let me just say a few words in English, look at my English level. But then I did not finish because the topic was a little anxious, the results did not react. I said I was a little nervous, Chinese teacher immediately change the Orz.
After z simply introduced myself English, the teacher asked me questions in English achievement, this is not that hard.
Then it is routine, and project experience / game experience, then try to do is to ask how the machine, I was rank7, the teacher said that I feel you this result is quite steady. I was listening to was very happy, although the last did not choose the North Division.
Final results, alternate.

Final destination

Not wanting to go East, the 28th day they reported a Master's special master and Zhongshan North Division, Zhongshan morning to a re-examination notice, admission notice to be given in the afternoon, the North Division did not respond.
North Division No. 29 at 8 am called and told me there is a place, but I was already picked up in Zhongshan, so finally went to the Zhongshan.
