Zscaler enables organizations to bring their own IP addresses to its Zero Trust Exchange platform. With Bring Your Own IP (BYOIP), companies can maintain their network identity while leveraging Zero Trust architecture. For many organizations, static IP addresses remain operationally important, despite the shift to Zero Trust architectures. SaaS platforms, partner networks, and regulatory agencies often still rely on IP address whitelisting for access control. Zscaler now supports both customer-assigned dedicated IPs and customer-owned dedicated IPs through BYOIP.
The core of the Internet is notoriously vulnerable to attacks, with Border Gateway Protocol (BGP) and DNS being particular weak points. So I set out to learn enough about what has been done to secure these components of the Internet's "core infrastructure" to be able to write something useful for our book. For this post I am going to limit myself to talking about BGP security, where it's fair to say that the results have been mixed.
