6. Networks

In this chapter:

Vulnerabilities

• Threats in networks: wiretapping, modification, addressing

• Wireless networks: interception, association, WEP, WPA

• Denial of service and distributed denial of service

Protections

• Cryptography for networks: SSL, IPsec, virtual private networks

• Firewalls

• Intrusion detection and protection systems

• Managing network security, security information, and event management

As we all know, much of computing today involves interacting remotely with people, computers, processes, and even wrongdoers. You could hide in your room and never pass anything to or receive anything from outside, but that would severely limit what you could do. Thus, some degree of external connectivity is almost inevitable ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
