Zero Trust Segmentation stops ransomware

Illumio provides protection that contains ransomware at source

The Problem of Ransomware

Organizations' assets and operations are being targeted by criminal gangs using more sophisticated ransomware with better evasion techniques. Defenses are regularly breached with detection systems, and need to work harder to identify and respond. Illumio stops ransomware at the source by containing the attack, preserving the resiliency of your organization.

Ransomware is a resilience issue

How does ransomware propagate?

Ransomware attacks follow a very predictable method of spreading across hybrid IT once they have successfully entered an organization. Two of the key tactics employed in this process are “Network and Domain Discovery” and “Lateral Movement”:

MITRE ATT&CK® Tactics Essential to Ransomware

Network Discovery helps the attacker build a better understanding of the target environment – what exists, how are they interconnected, what is accessible. 

Stop this and the attacker has less useful information about the victim’s network – the net effect is that they are either limited in the progress they can make or are forced to change their tactics to gather the same information, increasing the chances of detection. 

Lateral Movement enables the attacker to move to the next target or intermediary victim. 

Stop this and the attack cannot progress any further, significantly reducing the number of compromised resources. 

Limiting or preventing Network Discovery and Lateral Movement severely hampers the progress of the attack. However doing this successfully has been a challenge for organizations due to:

  • Poor visibility
    A lack of visibility makes it difficult to identify potential weak points in the system, and monitor the movements of the attacker
  • Too many open ports
    Commonly used ports left open create pathways for ransomware to quickly spread and take over the organization
  • A lack of proactive security defenses
    Relying solely on detection-based solutions has shown to be too slow in stopping an attack 

Zero Trust Segmentation directly addresses these challenges

How Zero Trust Segmentation mitigates ransomware

For organizations focused on improving their cyber resilience, Illumio identifies where they are most exposed and, through Zero Trust Segmentation, drastically reduces both their exposed attack surface and the ability of an attacker to spread.
