Greetings friend @teach-me.
In the view of the community this understanding is diverse but basically what is meant by a security system is a security that has a procedure that has been circulated in the sense that it is structured according to its application in the community or in an environment that is appropriate to its field.
Sometimes I have a hard time understanding your writing. I have to read several times to figure out the puzzle. This paragraph confused me.
In another aspect:
I did a check on your post with http://plagiarisma.net/ and it yielded only 44% original content.
Could it be that you made a lot of text quotes?
If so, I recommend that you should highlight these and indicate their origin.
Your friend, Juan.
