How do corporate firewalls protect against internal threats?

Corporate firewalls are designed to act as a protective barrier for internal networks and play a crucial role in safeguarding against internal threats. The selected answer accurately reflects this capability.

By implementing policies that regulate user behavior and access controls, corporate firewalls create a structured framework that dictates how employees interact with the network and its resources. This includes defining who can access specific data and systems, under what circumstances, and what actions they may perform. For instance, access controls can restrict certain sensitive areas of the network to only those individuals or groups who require it for their job functions. This minimizes the risk of unauthorized access and potential malicious activity from within the organization.

In addition to controlling who has access to what, these policies can also enforce security best practices, such as monitoring user actions and implementing appropriate sanctions for non-compliance. Together, these measures reduce the chances of internal threats, whether they arise from negligent behavior or intentional misconduct.

While logging external connections, restricting remote access, and ensuring data encryption are all important aspects of an overall cybersecurity strategy, they do not directly address the need to manage internal user behavior and access effectively. Therefore, the emphasis on regulatory policies and access control stands out as the most critical method by which corporate firewalls guard against internal threats.
