Security attacks

Security has been one of the top priorities for most people, in this day and age where computer attacks are frequently evolving. Computer security, nowadays has become complex and very confusing to many people. That is why we are going to share our knowledge in the different kinds of security attacks.


When we hear of the term security attacks the most common thought that will come out of our mind will be "hacking" or the "hackers". But in truth security attacks have many different forms.Here are the list of the different types of security attacks:

Virus, Worms and Trojan Horse

Computer viruses are computer programs that are capable of infecting a computer without its permission or without the knowledge of the user, leaving infections as it travels. A virus can be triggered or spread by the user because most of the viruses are attached to a executable file.

worms on the other hand are a sub class of a virus that, unlike a computer virus, can spread into your system without the need to be triggered by the user.

Trojan horse is a much vague kinf of virus that can make the user actually think that it is a safe software that appears useful but actually causes damage to the computer once installed.But unlike viruses and worms a trojan horse does not replicate itself.

When a host is uninfected the virus can easily spread by means of a removable medium, such as floppy disk, cd-roms, USB drives, or a user can easily send the said virus to another computer through the internet or through the network.

Denial-of-service attack(DoS)

Dos is a type of attack that can cause a computer resource to become unavailable to users. This type of attack usually are done by a person that causes traffic to a the system that will render it incapable of responding to the requests.

Logic Bomb

Logic bomb is also called a slag code, it is similar to a virus or a worm, but are dormant until an event occurs triggering its effect.

Hacker attacks

These are attacks that aren't caused by a certain software or virus, instead it makes use of the weak spot in the system.Here are the different hacker attacks:

Ip spoofing - the attacker fakes its own IP address to make the user think it was coming from a different source.

Man in the middle attack - makes use of open session to attack the user using IP spoofing, meaning computer a will think that computer b is still the one in communication, while in truth another party has already stolen the said session.

DNS poisoning - the attacker creates a false DNS information to be sent, that can cause traffic to be diverted. When the DNS information is sent the attacker can continue to reply using additional false information which the requesting DNS server may cache. Once the user attempts to log on to the said false DNS, all the user information can be retrieved by the false DNS or the attacker itself.

Password cracking - the attacker retrieves a password to gain unauthorized access.
