Web-based attacks

These are the attacks which occur on a website or web applications. Some of the important web-based attacks are-

    • Volume-based attacks - Saturate the bandwidth of the attacked site, and are measured in bit per second.
    • Protocol attacks - It consumes actual server resources, and is measured in a packet.
    • Application layer attacks - To crash the web server and is measured in request per second.

Dictionary attacks

  • This type of attack stored the list of a commonly used password and validated them to get original password.

URL Interpretation

  • It is a type of attack where we can change the certain parts of a URL.

File Inclusion attacks

  • It is a type of attack that allows an attacker to access unauthorized or essential files which is available on the web server or to execute malicious files on the web server by making use of the include functionality.

Man in the middle attacks

  • It is a type of attack that allows an attacker to intercepts the connection between client and server and acts as a bridge between them.

System-based attack

These are the attacks which are intended to compromise a computer or a computer network. Some of the important system-based attacks are as follows-


  • It is a type of malicious software program that spread throughout the computer files without the knowledge of a user. It can also execute instructions that cause harm to the system.


  • It is a type of malware whose primary function is to replicate itself to spread to uninfected computers.

Trojan horse

  • It is a malicious program that occur unexpected changes to computer setting and unusual activity, even when the computer should be idle. It misleads the user of its true intent.


  • It is a method that bypasses the normal authentication process. The developer may create a backdoor so that an application or operating system can be accessed for troubleshooting or other purposes


  • A bot is an automated process that interacts with other network services. Common Examples of bots program are the crawler, chat room bots, and malicious bots.
