Today’s modern security devices not only must understand the network, but they must also be fluent in the language of our applications. In this video, you’ll learn about security devices that can protect your network by watching application flows.
Firewalls now examine port numbers and applications as they traverse the network, but what’s protecting our servers from malicious user input? In this video, you’ll learn how a web application firewall (WAF) can protect from attacks that take advantage of unexpected application use.
Few things are more frustrating than having to sort through an email inbox that’s full of unsolicited email. In this video, you’ll learn about spam filters and some common methods used to separate the legitimate email from the spam.
If you ever want to know exactly what’s happening on a network, then you need a protocol analyzer. In this video, you’ll learn about protocol analyzers and how they can be used to monitor traffic and solve network problems.
IDS and IPS technology can watch for a wide variety of attacks by examining the traffic as it passes through the network in real-time. In this video, you’ll learn about IDS/IPS technology and the identification technologies that they use.
We’re an increasingly mobile workforce, so we therefore need technologies to keep us secure while we travel. In this video, you’ll learn how VPN concentrators can be used to provide encrypted tunnels from our favorite coffee shop to our corporate network.
As technology as improved, we’ve added more and more functionality to our security gateways. In this video, you’ll learn about unified threat management appliances and the functionality they bring to securing our network resources.
If you need to expand the capacity of your applications and network resources, you’ll need to use technologies like load balancers and proxies. In this video, you’ll learn how load balancers and proxies can be used to increase the scale of your network capacities.
The fundamental technologies in almost every network are switches, routers, and firewalls. In this video, you’ll learn how these devices are used to connect and protect our network devices.
CompTIA’s Security+ is a popular IT certification, and the certification topics range from networking to cryptography. In this video, I’ll give you an overview of the Security+ certification and I’ll give you some tips to help with your exam testing experience.
