Like the name suggests, it is a branch in the field of computer studies and information technology which helps to protect the data and information, often precious and valuable, from being stolen from a particular device. Ensuring ones computer security plays an important role in this regard.
Cut down threats of stealing
This “stealing” can mean many things, like overriding the existing data with other irrelevant data, copying the data without the consent of the owner of it, implanting virus in the machine so that there is a source of constant and almost irremovable corruption in the device, or which is most often considered the worst of all these, the leaking of personal information online which not only violates one’s privacy but also integrity as a human being.Therefore it is absolutely essential to take necessary steps against it to make sure that such threats to people are eradicated to a great extent if not completely removed from existence without a trace of it.
Steps to be taken
There are several ways to ensure that such security is maintained in a system. They are as follows
1) By limiting physical access to a computer to a selected few whom the company or the owner knows to be trustworthy
2) By installing new and improved hardware devices which ensure that the computer is not too much dependent on the software programs inside it. The reason behind this is, it is easier to hack into a web of software programs than to physically remove a hardware device from a computer which is more often than not located at a considerable distance from the hacker.
There are three layers of threat to any good computer security service scheme. They are, hacking, cracking and phreaking. One needs to ensure that the system is well protected against all of these simultaneously to be one hundred percent sure about the safe keeping of the data that is in the device.
One can take many measures to further solidify the security of one’s device. These include updating the software in it every now and then so that the malware has a hard time updating itself continuously to keep up to the pace of updating that the device is going through, one can use many levels of firewalls, paid anti-viruses, long passwords with numbers and special characters to make sure nobody can easily guess them. These passwords also need to be arbitrary so that people who know the owner cannot access it without his consent.
Now that you know the nitty gritty of computer security, keep unwanted anomalies away by being extra conscious.
