Regardless of whether or not you are using your access control system for your home, your garage, or your business, you are going to need to make absolutely sure that it is not compromised. Access control systems can be compromised if a person who is not supposed to have access to a certain area is able to gain entry. Here are some tips for keeping a number-reliant access control system secure and avoiding having a security breach.
1. Make the Code Long Enough to be Difficult to Guess, but Not So Long That People Need to Write it Down
The first thing that you are going to need to do is create a code that is going to be too long for people to guess easily by brute forcing their way in. You are going to want to choose a number that is between 7 and 9 digits long because someone trying to gain access illegally will have to try, in the worst case, between 10,000,000 and 1,000,000,000 different combinations in order to gain entry. If you make it much longer than 7 to 9 digits, then there's a good chance that people are not going to have an easy time remembering the code and they are going to need to store the code in their unsecured phone or on a piece of paper that could be easily lost.
2. Tell People the Code in Person and Force Them to Memorize it on the Spot
Whenever you give out the access control system's code, you are going to want to tell the person in person because email addresses and text messages are easily intercepted or hacked. By telling the person the code in person, you will be able to avoid having to worry about electronic spying.
Once you tell the person the code, you are going to want to stay in the room with him or her and wait for him or her to memorize the code. It should only take a few minutes for a person to memorize the code and it is worth the extra time to avoid having anyone send the code to themselves in a text message or write it down.
3. Change the Code Regularly
Finally, make sure that you change the code regularly in order to make sure that, should the code have been compromised, that you can regain your security and lock the person with illegitimate access out. When you give the new code, make sure that you follow the above two tips.
