Firewalls Questions
The role of firewalls in protecting against advanced persistent threats (APTs) is to act as a barrier between an organization's internal network and external networks, such as the internet. Firewalls monitor and control incoming and outgoing network traffic based on predetermined security rules. They inspect packets of data, analyze their content, and determine whether to allow or block them based on the defined rules. By doing so, firewalls can prevent unauthorized access, detect and block malicious activities, and provide an additional layer of defense against APTs.
