Võrgurünne

Võrgurünne, also known as a cyberattack or network attack, refers to any deliberate attempt to disrupt, damage, or gain unauthorized access to a computer system, network, or digital device. These attacks are carried out by malicious actors who aim to exploit vulnerabilities in software, hardware, or human behavior. The motivations behind võrgurünne vary widely, including financial gain, espionage, activism, or simply causing disruption.

The methods employed in võrgurünne are diverse and constantly evolving. Common types include malware (viruses, worms, ransomware), phishing (deceptive attempts to obtain sensitive information), denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks (overwhelming a system with traffic), man-in-the-middle attacks (intercepting communications), and SQL injection (manipulating databases).

The impact of a successful võrgurünne can be severe, leading to data breaches, financial losses, reputational damage, and disruption of critical services. Individuals, businesses, and governments are all potential targets. Defending against võrgurünne requires a multi-layered approach, incorporating robust security measures such as firewalls, antivirus software, intrusion detection systems, regular software updates, strong password policies, and comprehensive user education on cybersecurity best practices. Continuous monitoring and rapid response capabilities are also crucial for mitigating the effects of an attack.
