So much of what we do now is automated. And that is how it is supposed to be in the computer era. There is no reason to have computers if they are not able to take over the day to day grind. We need to be able to have computers that make our life easier in order for us to be able to progress. But that does not mean that you still do not have to get in the deep of things sometimes to be able to sort out a problem. We need to be able to still hold on to our original knowledge so that we are able to fix the things that a computer has trouble solving. There are certain edge cases where the computer is going to have a problem and we are going to need to step in.
When it comes to computer security we still need to be able to take control when it comes to scanning the network. Right now all of that is automated but it is not a one hundred percent fully effective system. The bad guys are able to get their hands on the same software that is running your automated system and they are able to find out what works against it. It is the cases like this when you need to be able to take back the reigns and go in manually.
If you are in computer security and you do not know how to read a data packet then you really do need to go back and learn. The data packet is the key to what we know as the internet and being able to read them will help you solve a lot of problems early.
While reading a data packet is not complicated, it does take some time to get used to. This is especially true when you are getting used to the software that helps you manually analyze a data packet. There are a lot of free manuals and well made books that will help you build up your skills in being able to manually analyze a data packet. If you really want to become better when it comes to computer security I suggest that you really take the time and read some of this material. Without it, you are only as good as the automated software is.
