Network Security Tip of the Week [18]

We’re back with the network security tip of the week. This week’s tip looks at the importance of network segmentation, which has been a hot topic in the recent weeks over some high profile breaches in the news. Network segmentation is also an important aspect of PCI-DSS where sensitive cardholder data must be separated from the rest of the network in a “PCI Zone”. Michael from the US suggests the following:

“Create physically separate networks according to the importance of the business functions performed over those networks. Create custom-tailored firewall rules according to those functions and importance levels.”

Thanks Michael for the tip. To our readers, if you have a good network security tip to share, please feel free to do so. Send us an email, or share with us via Facebook, Linkedin or Twitter, or of course simply comment on the blog!
