Computer Security or IT Security is a global demand to protect our computer systems from the malicious attackers from doing any damage to our hardware, software as well as disruption of the services provided. So Computer Security involves controlling our physical access as well as protecting against the harm that occurs via network access, data, and code injection.

Attackers often think ahead than a problem solver so always keep in mind that they are frequently trying or using different attacking techniques and methods we may not be aware of to discover our confidential personal or business information. So we have to be mindful of these facts by being extra vigilant when online. Then only, secureness of our information becomes possible from our site.

There are several types of computer security threat in modern time; a few of them are mentioned here:

  1. Hacking

A very great term for the security breach is hacking; it is an action taken by some anonymous to gain unauthorized access to a computer. Hackers find weaknesses in our security settings to access our information, install a Trojan horse for creating a backdoor to discover our confidential information. There is even more attack you can search for like Direct-access attacks, Eavesdropping, Spoofing, Tampering, Privilege escalation, Phishing, Clickjacking, Social Engineering, Virus, Worms, Spyware, Scareware, Adware, Exploit, Dialer, Dropper, Fake AV, Bluejacking, Boot Sector Virus, etc.
