What type of security component did Bob enable to protect his laptop from network threats?

  1. Anti-virus software

  2. Network security devices

  3. Intrusion prevention systems

  4. Data encryption tools

The correct answer is: Network security devices

Bob enabled network security devices to protect his laptop from network threats. Network security devices play a crucial role in monitoring and controlling the incoming and outgoing network traffic based on predetermined security rules. These devices can include firewalls, intrusion detection systems (IDS), and other security appliances designed to prevent unauthorized access, block malware, and mitigate various types of network-based attacks. Using network security devices offers an effective barrier against threats that come from external sources, thereby safeguarding sensitive data and preventing exploits that could compromise the integrity and availability of the laptop’s resources. Such devices actively analyze network traffic for signs of malicious activity and can respond in real-time to potential threats by blocking these attacks before they reach the system. Other choices each represent important aspects of network security but are not as directly related to the context of protecting a laptop from network threats in the manner suggested by the question. Anti-virus software focuses on detecting and removing malware from the individual device, while intrusion prevention systems, though similar to network security devices, are often more specialized types of devices that can block malicious activities after detection. Data encryption tools secure the data itself rather than specifically protect against network threats, making them essential for safeguarding data privacy but not the first line of defense against network-based attacks.
