Hyökkäystyypejä

Hyökkäystyypejä refers to the classification of different methods used to compromise a computer system or network. These categories help in understanding the threats and developing appropriate security measures. Broadly, hyökkäystyypejä can be divided into several main groups.

One common category is malware, which includes viruses, worms, trojans, ransomware, and spyware. These are malicious software designed to infiltrate systems, steal data, disrupt operations, or gain unauthorized access. Another significant category is social engineering, which exploits human psychology rather than technical vulnerabilities. Phishing, baiting, pretexting, and tailgating are examples of social engineering tactics used to trick individuals into revealing sensitive information or performing actions that compromise security.

Network attacks form another crucial area. These involve exploiting vulnerabilities in network infrastructure or protocols. Examples include denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks, which aim to overwhelm a system with traffic, making it unavailable to legitimate users. Man-in-the-middle (MITM) attacks intercept communication between two parties. Password attacks, such as brute-force or dictionary attacks, attempt to guess or crack user credentials.

Exploitation of software vulnerabilities, such as zero-day exploits, also constitutes a major hyökkäystyyppi. These attacks target weaknesses in software that are unknown to the developers, making them particularly difficult to defend against. Finally, physical attacks involve gaining direct access to hardware or facilities to compromise systems, though this is often considered distinct from purely cyber attacks. Understanding these diverse hyökkäystyypejä is fundamental to building robust cybersecurity defenses.
