Heat maps visually show the signal strength of wireless networks in a physical space. By analyzing a heat map, you can identify how far your Wi-Fi signal extends-especially if it's bleeding into surrounding buildings.
Once identified, you can then reduce the power of the access points or adjust antenna placements to minimize external signal leakage, thereby reducing visibility and access from unauthorized external devices.

Mitigate is the risk management strategy that involves reducing the likelihood or impact of a risk.
If a legacy application is critical to business operations and there are preventative controls that are not yet implemented, the enterprise should adopt the mitigate strategy first to address the existing vulnerabilities and gaps in the application. This could involve applying patches, updates, or configuration changes to the application, or adding additional layers of security controls around the application. Accept, transfer, and avoid are other risk management strategies, but they are not the best options for this scenario. Accept means acknowledging the risk and accepting the consequences without taking any action. Transfer means shifting the risk to a third party, such as an insurance company or a vendor. Avoid means eliminating the risk by removing the source or changing the process. These strategies may not be feasible or desirable for a legacy application that is critical to business operations and has no preventative controls in place.

A saved setup file with predefined parameters supports infrastructure as code and configuration templates. This ensures cloud resources are deployed with secure, repeatable, and consistent settings before being promoted to production.

A self-signed certificate is not trusted by browsers because it is not issued by a recognized certificate authority, leading to certificate warnings when users connect over HTTPS.
