[konigsberg]

Hey Guys, I wanted to know what is Bugs and Backdoors? It is mostly used as technical terms but I am not aware whether it is or not? I have some idea about bugs which means mistakes but in what sense? I don’t know where its specifications of program done or not? Backdoor, according to me are also similar bugs but I doing know what is it actually? If anyone who is aware of this query then please let me know its solutions I am eagerly waiting to know about it.

A backdoor is a feature of a program that can be used to make it act in some way that the person who is running it did not intend. Back doors are shortcut entry points to software or networks i.e. entry without going through authentication mechanisms. The only solution for backdoor attacks is double and triple checking of every piece of software before implementation. In order to save from the backdoors, cleaner solutions are also available which work in similar manner as the antivirus utilities.

These are the programs which when stored on the target systems, may allow easy access to hackers or give them sufficient information about the target to carry out the attacks. There are several backdoor programs used by the hackers. These are like automated tools, which carry out the destructive jobs for the hackers. This is how backdoors affects your computer system and you are not aware of it. One should be very careful otherwise they can be targeted.

A bug is something in a program that does not meet its specification. A bug may refer to some kind of problem in the software, which is undesired by its author. A bug in our language can be said as the human mistakes made undesirably. These mistakes can be solved as it is made by humans. So, it can be also placed or fixed by humans. You might find it when you are executing a program and then it can be found and fixed also.

The administrator should be checking for all the input correctness at every point. If the program has fixed size buffers of any sort, then it should be made sure that they do not overflow. If we use dynamic memory allocation, prepare for memory or file system exhaustion, and proper recovery strategies, which may need memory or disk space, too. This is the counter measures which one should take when this type of problem occurs.
