    -potential threat
    -viruses, worm, and Trojan horse
    Protecting equipments
    Protecting data
    -conclusion
    Firstly, Security threats are threats possible danger that might exploit a vulnerability to breach security and thus cause possible harm.
    There are two types of security threat namely physical and data security threats.
    Physical threat can be classified in different forms like, theft, damage or destruction of the computer.
    Data threat can also be classified as follows, removal, corruption, denial of access, unauthorized access, theft of information.
    There are some potential threat than occur also to our computer security, and they are mainly classified into two which are; external threat and internal threat.
    External threat is the one through which outside users can easily attack in an untrusted and destructive way
    Internal threats are those done by employees maliciously or accidentally.
    There are also viruses, worms and Trojan horses that are used to attack a computer system.
    Viruses are computer soft wares that are created by an attacker. These viruses usually collect sensitive information to alter or destroy information .
    Worm is a self-replicating program that uses the network to duplicate its code to the host on the network.
    Trojan horses is technically a worm and is named for the ability of getting past computer defaces by pretending to be something useful.
