Which of the following security policies will you implement to keep safe your data when you connect your Laptop to the office network over IEEE 802.11 WLANs? Each correct answer represents a…

Personal firewall software filters inbound and outbound traffic on the laptop itself, blocking unauthorized connections and malicious traffic that can propagate over an untrusted wireless network. It acts as a host-based control independent of the network infrastructure.

An IPSec-enabled VPN encrypts all traffic between the laptop and the corporate network, protecting data confidentiality and integrity even if the 802.11 wireless medium is intercepted or compromised. IPSec provides authentication and encryption at the network layer.

Nmap is a port scanner used for network reconnaissance and inventory, not a security policy that protects data - using it without authorization can itself be a policy violation.

A protocol analyzer (packet sniffer) passively captures and displays network traffic for diagnostic purposes; it does not protect data and could actually expose sensitive information if used or intercepted by an attacker.
