What security strategy is characterized by multilayered protection to minimize attacks on organizational assets?

The security strategy characterized by multilayered protection to minimize attacks on organizational assets is known as defense-in-depth. This approach involves deploying multiple layers of security measures throughout an organization's infrastructure, ensuring that if one layer is breached, others remain intact to mitigate the risk of an attack. Layers can include physical security, network security, application security, and endpoint security, among others.

By using defense-in-depth, organizations create a more robust security posture. This means that attackers face multiple barriers, making it significantly more challenging to successfully compromise the system. Additionally, this strategy not only focuses on preventing attacks but also emphasizes detection and response capabilities, enabling organizations to react effectively to incidents should they occur.

The other options do not embody the concept of multilayered protection like defense-in-depth does. For instance, a three-way handshake is a process used in TCP/IP networks for establishing a connection and ensuring reliable communication but does not relate to an overall security strategy. Likelihood analysis pertains to assessing the probability of certain risks occurring, while covert channels involve unauthorized communication paths within a network, neither of which encapsulate a comprehensive defensive strategy.
