What is the key to breaking the Cyber-Attack Lifecycle during the Installation phase?

The key to breaking the Cyber-Attack Lifecycle during the Installation phase is network segmentation and the Zero Trust model. During this phase, an attacker attempts to install malware or backdoors on the compromised system to maintain access and control over the environment.

By implementing network segmentation, organizations can limit the ability of an attacker to move laterally within the network. This practice involves dividing the network into smaller, isolated segments, making it more challenging for an attacker to access systems and data across the entire network. The Zero Trust model complements this approach by operating under the principle that no one—inside or outside the network—should be trusted by default. Instead, every access request should be verified, regardless of the user's location. This means that even if an attacker has installed malware on one part of the network, their ability to exploit other segments can be significantly reduced if those segments operate under strict access controls.

In contrast, while strong passwords, regular software updates, and increased user training are important components of cybersecurity, they do not specifically counteract the tactics employed during the Installation phase as effectively as a layered approach involving network segmentation and the Zero Trust philosophy. Strong passwords can prevent unauthorized access, but if an attacker gains initial access, they can still proceed with installation.
