To secure the load balancer against basic attacks, a fundamental step the network administrator should perform is **to implement access control measures**. This includes setting up rules to restrict incoming traffic to only legitimate users and trusted sources. Additionally, the administrator should consider the following key actions:
1. **Configure firewall rules**: Ensure that the load balancer is protected by firewalls that allow only necessary traffic types (e.g., HTTP/HTTPS) and block malicious traffic.
2. **Enable SSL/TLS**: Use secured connections to encrypt data in transit, preventing man-in-the-middle attacks and ensuring that sensitive information is not exposed.
3. **Regular updates and patches**: Keep the load balancer firmware and software up-to-date to protect against known vulnerabilities.
4. **Implement logging and monitoring**: Set up logging to detect unusual traffic patterns or attacks, which can help in incident response.
5. **Use web application firewall (WAF)**: Deploy a WAF along with the load balancer to provide an additional layer of protection against web-based attacks like SQL injection or cross-site scripting.
By implementing these measures, the network administrator can secure the load balancer effectively against various threat vectors.
