1. What is a Firewall in Network Security? - Role & Use
The network firewall is an important piece of equipment that protects your network from hackers and other cyber criminals. Its use is essential if your business is connected to the Internet, and it's highly recommended for residential users too.
2. Firewalls in Network Security: Features & Functions
Firewalls operate as a type of fence to protect what's coming into and leaving your network. In this lesson, you'll learn more about their functionality and some features that are common in today's firewalls.
3. SSH Proxy Tunnels
In this lesson, we will examine what proxy tunneling is all about and understand what SSH proxy tunneling is. We will examine the three main uses of SSH proxy tunnels.
4. Intrusion Detection Systems (IDS) in Data Security
In this lesson, we'll take a look at data security, what it is, what intrusion detection systems are, some types of intrusion detection systems, and some methods used for intrusion detection.
5. Intrusion Prevention System (IPS): Definition & Types
An intrusion prevention system is an added layer of protection for your computer network. In this lesson, you'll learn more about this system, how it works, and what it does to safeguard your network.
6. What is Unified Threat Management (UTM)?
Unified Threat Management is an evolutionary step in firewall and network security technology. It helps to increase network security by making it easier and less costly. We'll learn about what it is and its benefits in this lesson.
