What aspect of cybersecurity can a layered approach improve?

A layered approach to cybersecurity, often referred to as defense in depth, significantly enhances detection capabilities. This strategy involves deploying multiple security measures at various points within the network, which allows for better identification and response to potential threats or breaches.

When organizations implement a layered approach, they create redundancies in security protocols. This means that even if one layer fails, others are in place to detect an intrusion. For instance, combining firewalls, intrusion detection systems, antivirus software, and security information and event management (SIEM) systems allows for more comprehensive monitoring of network activity. Each layer can provide distinct types of detection. For example, while firewalls might block unauthorized access attempts, intrusion detection systems can identify suspicious internal behavior.

By continuously monitoring traffic and analyzing data across different layers, organizations can improve their ability to detect and respond to threats that may otherwise go unnoticed. This holistic view enables quicker identification of potential security incidents and allows for a timely response, ultimately enhancing the overall security posture of the organization.

In contrast, cost efficiency, system performance, and user accessibility can be affected by the implementation of a multi-layered approach but are not direct improvements. For instance, while a layered approach may initially lead to increased costs due to the deployment of multiple security
