Importance of security

            No doubt, prevention of data theft like work related sheets or documents, passwords, credit card information, and bank account numbers etc. is very important in the communication at present since most of our daily tasks rely on the protection and security of paths for data.

            Data that is present in a computer can always be misused by intrusions which are unauthorized. The source codes of a program can be changed and modified by an intruder and can also use the email accounts or pictures of users for creating unethical and offensive content.

        In computer security, malicious intents can be a significant factor. Often, intruders use the computers of users for attacking other websites or computers for creating havoc. That is why it is so important to save the computer against every possible and potential threat.

Some ways for protecting your computer:

Password protection: The most common way of securing computers and mobiles is using a password for locking the devices up. It is one of the most effective ways of making sure that your devices are completely secure and no one is able to trespass the barrier that you have set. There is just one thing that should be kept in mind when it comes to setting a password. You should not use just letters for a password. Other than using special keys and capital letters, you should also make use of spaces.

        It is true that you can use spaces for setting a password. This way, only you know where to put the space. You can either insert it at the end of the password or right at the beginning. This technique is not only effective but it is also more secure than the ones you normally use.

Fingerprint lock: This method is also becoming increasing popular and useful in securing devices from unwanted theft. It is preferred because it reduces the chances of a breach to minimum because no one else other than you can unlock the devices using your fingerprints. Most of the phones at the moment come with the technology for fingerprint scanner and you might find it intriguing that even some laptops now support this technology.

Fingerprint lock relies on the mark that you leave. That is why you should make sure that you fingerprints are not damaged or you won’t be able to get access to your device. In order to avoid this from happening, you can simply add two fingers or more.
