Final answer:
The appliance offering the broadest protection by combining several security functions is UTM, or Unified Threat Management. UTM devices include firewall, antivirus, content filtering, and intrusion prevention, providing comprehensive network security.
Step-by-step explanation:
The appliance that provides the broadest protection by combining several security functions is UTM, or Unified Threat Management. UTM devices are multi-functional and include features such as firewall, antivirus, content filtering, and intrusion prevention systems. By consolidating these security functions, UTMs offer comprehensive protection against a wide range of cybersecurity threats.
While NAT (Network Address Translation) helps mask IP addresses, NGFW (Next-Generation Firewall) offers advanced inspection capabilities, and WAF (Web Application Firewall) protects against web-based attacks, none of these provide as broad a spectrum of security features as a UTM. Therefore, for organizations looking for a single device that provides wide-ranging security defense mechanisms, a UTM would be the most suitable option.
The appliance that provides the broadest protection by combining several security functions is UTM (Unified Threat Management).
UTM is a comprehensive security solution that integrates multiple security functions into a single device. It combines features such as firewall, intrusion prevention system (IPS), virtual private network (VPN), anti-malware, web filtering, and more.
By combining these functions into one appliance, UTM offers a centralized and efficient approach to security, simplifying management and reducing costs. It provides a broader scope of protection compared to other options listed, such as NAT (Network Address Translation), NGFW (Next-Generation Firewall), and WAF (Web Application Firewall).
