Future Business Leaders of America (FBLA) Cybersecurity Practice Test

What is a key feature of IPsec?

1. It is used for VPN but does not ensure security

2. It operates at the transport layer of the network

3. It provides multiple security services including encryption

4. It provides no authentication capabilities

The correct answer is: It provides multiple security services including encryption

A key feature of IPsec is that it provides multiple security services, including encryption, which is essential for securing internet protocol communications. IPsec operates by establishing a secure connection over potentially insecure networks by encrypting the data transmitted and ensuring that it can only be read by the intended recipient. This encryption protects the confidentiality of the data in transit, while IPsec can also provide integrity and authentication services. By offering these multiple layers of security, IPsec helps to establish a secure virtual private network (VPN), making it a critical technology for safe communications over the internet. The encryption ensures that even if data packets are intercepted, they cannot be read by unauthorized parties. This comprehensive security approach is what makes IPsec a fundamental technology in the realm of network security.
