What is meant by basic boundary security?

• A. Monitoring internal network performance
• B. Measures like firewalls and intrusion detection systems
• C. Only user password management
• D. Mobile device management strategies

Answer: (B)

Basic boundary security refers to the fundamental measures implemented to protect the perimeter of a network from unauthorized access and potential threats. This involves technologies and practices that create a defensive barrier between internal networks and external entities. Firewalls and intrusion detection systems are key components of these measures. Firewalls help filter incoming and outgoing traffic based on predefined security rules, while intrusion detection systems monitor network traffic for suspicious activity and provide alerts regarding potential security breaches. Together, these tools form a crucial layer of security that helps to prevent external attacks and protect sensitive information within the network.

In contrast, monitoring internal network performance primarily focuses on the health and efficiency of the network, rather than securing it from external threats. User password management, while important for protecting individual accounts, does not encompass the broader concept of boundary security. Mobile device management strategies focus on securing mobile devices and ensuring compliance with organizational policies, but again, do not address the perimeter defense aspects that basic boundary security entails. Therefore, the correct answer encapsulates the essential measures that protect the network boundary itself.
