Now day’s computer is being used in almost all the fields. It is used in banks as well as the national security too is totally dependent on some super computers installed at pentagon. However a person is needed to supervise the whole process. Let me tell you that this is the most important post in any company or in some government agencies like the national security center in Pentagon. You will have to go through a sever interview session before you are selected for this post.
Some of the interview questions are as follows:
1. Why do you feel that you are the best choice?
There can be many answers to this. You can say it on behalf of windows or you can go in deep about the super computers. However some of the concepts are same in all the operating systems or types of computer. One such similarity is the firewall. You will definitely have to make sure that you talk about the firewalls. You will also have to talk about the antivirus software as well as cryptography.
2. Have you any idea about the cryptography?
Yes, cryptography is the study of hiding information from the entire source which is not permitted to know about the information. You should know about the cryptography in detail. Otherwise you might fell in the trap of speaking irrelevant facts. If you have more knowledge then it is well and good. But you will have to make sure that you speak what has been asked from you. Do not speak out irrelevant things. It will definitely harm your chances of being selected. I feel you must be remembering some interviews in which you might have done this mistake. However there is always a next interview for you. So do not panic and study hard.
3. Do you know about the excess-3 code?
Yes this was used by Julius Cesar in the past. The logic was that suppose we want to code “hello” with the help of excess-3 then it will become “KHOOR”. Hence you will find out that the encrypted data is very hard to decrypt.
4. Name two latest cryptographic encryption standards?
AES which is the abbreviation for advanced encryption standard as well as DES are some of the latest encryption standards.
5. How many layers are there in OSI model?
There are seven layers in the OSI model.
6. On which layer is firewall installed?
Firewall is installed at the network layer.
These are some of the questions which might be asked from you when you will go out to give the interview of the security architect. Make sure that you prepare hard so that you are able to clear the interview easily.
