A small start-up has recently launched its first web application. To ensure high availability and to handle implement a load balancer in its network infrastructure. The network technician must secure the load balancer against basic threats. What is the fundamental step the network technician should take to secure the load balancer? Enable all available features on the load balancer. Configure the load balancer to operate in fail-closed mode. Implement an intrusion detection system (IDS) alongside the load balancer. Disable unnecessary services on the load balancer.

One of the most effective ways to secure a load balancer is to disable unnecessary services on it. By minimizing the number of active services, you reduce potential entry points for attackers and limit the overall attack surface, making it much harder for them to exploit vulnerabilities. This step ensures that only essential functions are running, while the rest are kept off, fortifying your defenses. In real-world application, businesses that prioritize security often conduct regular audits of their load balancer configurations. For instance, by using automated tools to identify and disable any unneeded services, companies can maintain a lean and secure infrastructure while ensuring high performance. This proactive approach not only prevents potential breaches but also enhances the overall reliability of the web application.
