Gesundheitswesen: Erpressungen auf Höchststand, Stress bei den Teams
Schwachstellen und Kapazitätsprobleme sind die Hauptursachen für Ransomware-Angriffe im Gesundheitswesen, wobei die Verschlüsselung von Daten auf ein Fünfjahrestief gesunken ist. Gleichzeitig sind die Lösegeldforderungen und -zahlungen zurückgegangen, während die Angreifer vermehrt auf reine Erpressungsangriffe setzen. Die Belastung der IT- und Cybersicherheitsteams ist gestiegen, was sich in erhöhtem Druck, Angst und Stress äußert. In der aktuellen……

Preventing DNS filtering bypass by Encrypted DNS (DoT, DoH, DoQ)
DNS over HTTPS (DoH) and other encrypted DNS protocols like DNS over TLS (DoT) & DNS over QUIC (DoQ) enhances user privacy and security by encrypting DNS queries in transit, shielding them from eavesdropping, tampering, and censorship on untrusted networks. This prevents ISPs and local attackers from logging or manipulating domain resolutions, fostering a more…
