Internet has been major part of our daily life. but along with the pros of internet, It also has its cons which can be very dangerous. I have came across few fake mail on email saying that they are from xyz big compamy and will land you a job if you pay they so and so amount. This emails are fake as they are send from some random mail address and not the company mail address. So people should take care before trusting this fake people. There have been few cases in delhi in recent times where such company was found guilty. Apart from this our password is also now secured as there can brute force attack take place. In Brutte force attack, hacker tries all possible possibilities of password and they crack the system. So we should always put a very strong password to avoid such attack. There are also system which can make brutte force attack. So more strong encryption technique should be used so that this brutte force attack don’t take place. There are few technique in which multiple keys are used to encrypt the password
