DoS and DDoS attack: Meaning & Contrasts

Attacks, DNS, , , ,

DoS and DDoS attack represent cyber threats that disrupt online services. In a DoS (Denial of Service) attack, a single source floods a system, overwhelming it and causing a shutdown. DDoS (Distributed Denial of Service), however, employs multiple sources, making it harder to mitigate. While DoS focuses on one weak point, DDoS exploits multiple vulnerabilities simultaneously. DoS is like clogging a single lane, and DDoS is blocking an entire highway. Both DoS and DDoS attack aim to disrupt access, but DDoS is more complex and powerful due to its distributed nature. Organizations must strengthen their networks to prevent these disruptive attacks. Read more about the difference between DoS and DDoS attacks!

DNS tunneling briefly explained

Attacks, DNS, , ,

DNS tunneling is a malicious technique that exploits the Domain Name System’s (DNS) capacity to transmit data. By implanting data within DNS queries and responses, attackers can bypass network security measures. This method is often used to exfiltrate sensitive information or establish unauthorized communication channels across firewalls. However, its abnormal traffic patterns can raise alarms. Security measures, like DNS filtering, help detect and prevent DNS tunneling. Maintaining DNS security is crucial to prevent this sneaky method of data transfer.
