One of the most effective ways to protect an application server is to use a screened subnet. A screened subnet is a network segment that is isolated from both the internet and the internal network by two firewalls. The application server is placed in the screened subnet, also known as the demilitarized zone (DMZ), and only the necessary ports are opened for communication. This way, the application server is shielded from external attacks and internal breaches, and the impact of a compromise is minimized.

COPE (Corporate-Owned, Personally Enabled) devices allow companies to manage and harden company-owned devices while still enabling limited personal use, reducing security risks while maintaining compatibility with corporate resources.

A misconfiguration vulnerability occurs when system settings - such as those deployed via group policy - are set insecurely, unintentionally weakening security and increasing exposure to threats.

A nation-state is a threat actor that is sponsored by a government or a political entity to conduct cyberattacks against other countries or organizations. Nation-states have large financial resources, advanced technical skills, and strategic objectives that may target critical systems such as military, energy, or infrastructure. Nation-states are often motivated by espionage, sabotage, or warfare.
