Technologies and tools for safer networks
Is your data safe? Are your borders protected? This month we examine some expert techniques for building more secure networks.
Real admins think about security all the time, and even if you're a casual user, it pays to know what the intruders know. Services that once were safe are now wide open unless you keep current with the changing times. This month, we examine some security strategies from the experts.
We start with a study on how to protect Voice over IP (VoIP) networks from eavesdroppers and other intruders. You'll learn about some of the encryption technologies available with VoIP and get some practical tips on isolating and protecting voice communications.

Our next article describes how to use one-time passwords to add two-factor authentication to a secure website. You'll learn about the OTPauth PHP library, and we'll provide a detailed example showing how to set up your own online one-time password system.
The last article in this month's cover set looks at hping, a handy tool for creating test packets to explore intrusion scenarios and check the functionality of firewalls. But that's not all. If you're still looking for more inspired reading on security, turn to our Sysadmin section for an interesting case study on how to hack NFS 3.
You'll never have the perfect network or the perfect tools – the world of network security is changing all the time – and since you can never really pin it down, maybe the best strategy is to read on …
