DNSkárosodásokat

DNSkárosodásokat, or DNS damage, refers to disruptions or corruption within the Domain Name System. The DNS is a hierarchical and decentralized naming system for computers, services, or any resource connected to the Internet or a private network. It translates human-readable domain names, like example.com, into machine-readable IP addresses, such as 192.0.2.1, which are necessary for locating and identifying services on networks.

DNSkárosodásokat can manifest in several ways. One common form is DNS poisoning or cache poisoning, where an attacker introduces false data into a DNS resolver's cache. This redirects users to malicious websites instead of the legitimate ones they intended to visit. Another type is DNS hijacking, where an attacker gains unauthorized control over a DNS server or a domain's registration, allowing them to redirect traffic.

Consequences of DNSkárosodásokat can include phishing attacks, malware distribution, denial-of-service (DoS) attacks by making services unreachable, and general loss of trust in online services. Malicious actors exploit DNS vulnerabilities to intercept communications, steal credentials, or disrupt network operations. Preventing DNSkárosodásokat involves implementing security measures like DNSSEC (Domain Name System Security Extensions), which cryptographically signs DNS data to ensure its authenticity and integrity. Regular monitoring of DNS infrastructure and prompt patching of vulnerabilities are also crucial for maintaining DNS health.
