By Anna Shirokova Brute force attacks have existed long before the Internet. As a cryptanalytic attack, it started being used as an attempt to access encrypted data when there were no other options available. With the rise of the Internet, this type of attack was quickly adopted. In a nutshell, a brute force attack consists of systematically trying different credentials until the correct combination […]

Im menschlichen Körper schützt das Immunsystem im Inneren vor Gefahren durch unerwünschte Keime und Viren.
Warum schützen Unternehmen Ihre Netzwerke also nicht von innen, sondern legen i.d.R. viel mehr Wert auf den Schutz der Außengrenzen? Das war über viele Jahre sicherlich ein guten und richtiger Ansatz, weil es nur kontrollierte Zugänge ins Netz gab. Durch die immer stärker zunehmenden Themen Cloud, Mobilität und IoT aber verschwimmen solche festen Grenzen und Übergänge.
Die Gefahr eines Eindringens in Ihr Netzwerk steigt.
Wenn man von üblichen Netzwerkstrukturen ausgeht, hat ein einmal ins LAN gelangter Schädling leichtes Spiel, sich zu verbreiten und Rechner und Server abteilungsübergreifend zu kompromittieren. Hier ist der zentrale Ansatzpunkt für das LAN-Immunsystem. Warum eigentlich muss ein Produktionsnetz mit der Personalabteilung in Verbindung stehen? Was macht der Bereich Vertrieb z.B. im gleichen Netzsegment, wie die Technik?
Eine interne Segmentierungs-Firewall schafft die nötigen Barrieren, damit sich Schadsoftware und Eindringlinge nicht ungehindert in Ihrem Netzwerk bewegen können.
Lesen Sie dazu gerne auch das Whitepaper unseres Technologiepartners Fortinet.
Neugierig, wie das Immunsystem Ihres Netzwerkes aktiviert werden kann? Sprechen wir drüber:
