Basics of Cyber Security
Introduction to Cyber Attacks (Note)
Introduction to Cyber Attacks
Cyber Attacks are malicious attempts to damage, disrupt, or gain unauthorized access to a computer system,
network, or device, with the intention of stealing sensitive information, extorting money, or causing harm.
Types of Cyber Attacks
There are various types of Cyber Attacks, each with their own methods and motivations. Here are some of
the most common types:
- Malware: Malicious software designed to disrupt, damage or gain unauthorized access to a system or
network. Examples include viruses, worms, Trojan horses, and ransomware.
- Phishing: Social engineering attack that tricks users into revealing sensitive information, such as usernames
and passwords, by disguising as a trustworthy entity.
- Man-in-the-middle attack (MitM): Attack where a cybercriminal intercepts and alters communication between
two parties to steal data or spread malware.
- Denial of Service (DoS) attacks: Attempts to make a network, service, or device unavailable by
overwhelming it with traffic or causing it to crash.
- SQL Injection: Attack that exploits vulnerabilities in a website's database to steal sensitive information.
- Zero-Day exploits: Attacks that exploit previously unknown vulnerabilities in software or hardware.
