If you are securing a server farm, then you probably manage a group of load balancers. In this video, you’ll learn about active/active and active/passive load balancing. << Previous Video: Proxies Next: Access Points >> As the name implies, a load balancer is designed to take a load of traffic and distribute it across multiple […]

Proxies have been used a security technology for many years. In this video, you’ll learn why proxies maintain this longevity, and you’ll learn the differences between a forward proxy, reverse proxy, and open proxy. << Previous Video: Router and Switch Security Next: Load Balancers >> A security technology that has stood the test of time

Your routers are switches connect to everything in the network, so they are prime targets for exploitation. In this video, you’ll learn about router ACLs, network access control, flood guards, and much more. << Previous Video: Network Intrusion Detection and Prevention Next: Proxies >> A router is a device that forwards traffic between different IP

If you want to stop an unwanted attack, then you’ll want to include an IPS as part of your defense-in-depth strategy. In this video, you’ll learn about intrusion detection systems and intrusion prevention systems, and you’ll learn how they work in both out-of-band and in-band response configurations. << Previous Video: VPN Concentrators Next: Router and

A virtual private network (VPN) is a valuable security technique that’s commonly used to protect data sent across insecure networks. In this video, you’ll learn about VPN technologies, types of VPN implementations, and how IPsec protocols are used to protect your data at the packet level. << Previous Video: Firewalls Next: Network Intrusion Detection and

If you have a network connection or operating system, then you certainly have a firewall. In this video, you’ll learn about firewall states, application-aware firewalls, and how to evaluate a firewall ruleset. << Previous Video: Vulnerability Types Next: VPN Concentrators >> What is a more ubiquitous security technology than the firewall? We use it everywhere.
