Role of Firewalls in Data Protection

Firewalls play a crucial role in protecting data from unauthorized access and cyberattacks. Let’s
understand how firewalls work and their importance in programmatic advertising.

How Firewalls Work

Firewalls monitor and control network traffic based on predefined security rules. They act as a
barrier between secure internal networks and untrusted external networks, blocking suspicious
access and preventing attacks.

Types of Firewalls

There are various types of firewalls, including network firewalls, application firewalls, and host-
based firewalls. Each type offers different levels of protection and is suitable for different use
cases.

Importance in Programmatic Advertising

In programmatic advertising, firewalls help protect servers, user data, and ad platforms from
cyber threats. They ensure that only authorized traffic can access systems and sensitive data,
enhancing overall security.
