Fix that lock…and get a spare key! Software updates, security patches and data backupsIf the lock to your home’s main door breaks, do you fix it or just let it be? My guess is, you would get a locksmith to fix it for you at the earliest. And, what do you do if you lose the key? Use the spare key, if you have one, to get into your home, right? The situation is kind of similar when it comes to security patches and updates for your software programs.
