Which of the following is a security feature that Involves the use of hardware and software to filter or prevent specific Information from moving between the inside network and the outs de network?
A firewall is a network security device (hardware or software) that monitors and controls incoming and outgoing network traffic.
It is designed to filter or prevent specific information from moving between internal and external networks, ensuring unauthorized access is blocked.
How a Firewall Works:
It uses rules and policies to determine whether to allow or block traffic.
Firewalls can be configured to prevent malware, hacking attempts, and unauthorized data transfers.
There are different types, including packet-filtering firewalls, stateful inspection firewalls, and next-generation firewalls (NGFWs).
Why Other Options Are Incorrect:
A. Authorization:
Authorization refers to user access control, ensuring users have the correct permissions, but it does not filter network traffic.
B. Architecture model:
An architecture model defines the structure of an IT system but does not actively prevent or filter data movement.
D. Virtual private network (VPN):
A VPN encrypts data and provides secure remote access but does not filter or block data movement between networks.
IIA’s Perspective on IT Security Controls:
IIA Standard 2110 – Governance emphasizes strong cybersecurity controls, including firewalls, to protect sensitive data.
IIA GTAG (Global Technology Audit Guide) on Information Security recommends using firewalls as a primary defense mechanism.
NIST Cybersecurity Framework and ISO 27001 Security Standards identify firewalls as critical tools for network security and data protection.
