Which technology should be installed to prevent unauthorized access to library resources?

• A. Antivirus software
• B. Data encryption
• C. A firewall
• D. Network monitoring systems

Answer: (C)

The installation of a firewall is essential for preventing unauthorized access to library resources. A firewall acts as a barrier between the internal network of the library and external networks, such as the internet. It monitors incoming and outgoing traffic and enforces security policies that determine what data can pass through. By filtering this traffic, a firewall can block unauthorized users from accessing sensitive information or resources in the library's network. This protective measure helps safeguard the library's digital assets, ensuring that only vetted users can access specific systems or databases. Firewalls can be configured to allow or deny traffic based on various parameters, such as IP address, port number, and protocol, thus providing a customizable security solution tailored to the library's needs. While antivirus software protects against malware, and data encryption secures information by making it unreadable to unauthorized users, a firewall is fundamentally designed to prevent unauthorized access in the first place. Similarly, network monitoring systems provide oversight of the network's performance and security but do not actively block access like a firewall does. Therefore, a firewall is the most appropriate technology for preventing unauthorized access to library resources.
