Quarantine : isolates the virus by putting it into and area where it can’t access and possibly harm to the rest of the computer system
Hacking : someone gaining access the computer system illegally. Hackers try to gain access to :
Damage your computer or network
Steal files (diaries/financial information i.e. credit numbers/product information to sell to a competitor)
Plant viruses
How to prevent hackers from accessing your network or computer :
Use a Firewall (both on a computer&network) the role of a firewall is to monitor incoming and outgoing traffic/files-if it suspects a suspicious incoming file-it will block it-if it suspects you are sending sensitive information over email/someone is trying to steal information remotely-it will block
A firewall will also block suspicious websites/applications an advise they are not reachable
Ethical Hacking : to protect someone’s computer network
The difference between anti-virus and firewall is that firewall is prevent the dangerous files to coming in and the important information to be going out. But anti-virus is just protecting the computer network from the virus.
Phishing : Involves sending an email that looks as though it comes from a legitimate organisation (bank or law firm). If the recipient clikcs on a link in the email, they will enter their personal details or account details.
Pharming : It’s another type of scam. It re-directs users from a genuine website to fake website that a pharmer can access to the data. To prevent pharming, you should check the top level domain which is appropriate or not.
Spamming : Spam in a junk mail. Opening a spam email and a link in an email could infect your computer such as virus. Sometimes, it takes off whole of the network.
Spyware : It’s a software that monitors and save the information typed by a user. The consequence would be the important data being taken.
