Adware, malware, spyware, and computer bots are few threats that prompt the use of a secure computer authentication system. Various methods are used in these processes. However, the stress has always been towards a software approach for solving the purpose of authentication.
Do not use easily predictable words; they don't even require a hacker to access the system through your account. Use passwords that are unpredictable. Set long ones, and use numbers and special characters for this aspect.
Remember your passwords; don't write them down anywhere. Hackers use various tools to know your passwords, but a long one with a number of special characters, will indeed gives them a lot of trouble.
They are among the very few hardware authentication processes, in which a simple card with an embedded circuitry is used for accessing the network. Each valid card for a particular network, when inserted into a particular circuitry, gives an output, which decides whether you will be allowed to enter into the network or not.
Now, let's talk about the normal computer security authentication processes that we can install (or use) at the local level. Setting up a BIOS password for your computer may not be the ultimate security option.
Setting up the administrator password is of utmost necessity. If this is not set, then any user can log into the computer, irrespective of the fact whether he has an account in that system or not.
These methods are just a few of the widely used authentication methods. In fact, the measures that we take for safeguarding our computer or network, are more important than the method itself.
Many of us have a habit of naming our networks after a protagonist from our favorite movie. This should be avoided, and networks should have sensible names that cannot be easily determined. If you are a network administrator in charge of a closed secure network, then it is always desirable to set your network visibility status to the invisible mode.
