    Cyber Attack

    What is a Cyber Attack?

    A cyber attack is an attempt to gain unauthorized access to a computer system or network. The purpose of a cyber attack is to disrupt, disable, destroy, or maliciously control a computer system or infrastructure.

    Who should care about cyber attacks?

    Organizations are concerned with cyber attacks because they disrupt business operations, and cause a loss of customer data, intellectual property, or both. Individuals are concerned about cyber attacks on themselves and organizations they do business with because cyber attacks typically result in their personal information being stolen.

    In all instances, cyber attacks cause significant financial harm to those involved.

    What are the most common types of cyber attacks?

    While there are many ways that cyber criminals will carry out an attack on an organization, most cyber attacks follow a similar pattern of attack techniques. Some of the most common types of cyber attacks are:

    • Malware
    • SQL injection
    • Zero-day exploit

    • Man in the middle (MITM)
    • DNS tunneling
    • Business email compromise (BEC)
    • IoT-based attacks
    • Password attack
