The key to breaking the cyberattack lifecycle during the Installation phase is to implement which of the following?

The Installation phase of the cyberattack lifecycle is critical because it represents the point at which an attacker successfully installs malware or maintains persistence within the target environment. To effectively break the cycle during this phase, the implementation of network segmentation, a Zero Trust model, and granular control of applications is essential.

Network segmentation limits the access and movement of legitimate users and potential attackers within a network. By dividing the network into smaller, manageable segments, organizations can contain and mitigate the impact of any security breaches that may occur. This containment prevents attackers from moving laterally across the network to access sensitive data or systems.

A Zero Trust model further strengthens defenses by assuming that threats could be both external and internal. This model requires strict verification for anyone who attempts to access resources on the network, regardless of their location. By never trusting by default and continuously validating user identities and access permissions, organizations can significantly reduce the chances of an attacker successfully installing malware.

Granular control of applications allows for precise management of what applications can run on endpoints and servers. By restricting unauthorized applications and carefully monitoring for any suspicious activity, organizations can prevent the installation of malicious software and maintain a more robust security posture.

Overall, combining these three strategies enables organizations to create a protective barrier that hinders unauthorized installations and
