In this new book you find the most important information to implement a Zero Trust Architecture and about the Zero Trust Network.

The Zero Trust Network is a security model based on the principle of
“never trust, always verify”. In traditional network architectures, once
a user gains access to the internal network, they are often granted
extensive trust and freedom to move within the system. This practice
can leave critical data and resources vulnerable to potential breaches.
However, the Zero Trust Network adopts a more cautious and
controlled approach to network security. It operates on the premise
that no user or device, whether inside or outside the network
perimeter, should be inherently trusted. Instead, every user and device
must be continuously verified before they are granted access to
sensitive resources.

Zero Internet:
The concept of Zero Internet complements the principles of Zero Trust
Network and aims to elevate security to an unprecedented level,
particularly beneficial for businesses and organizations dealing with
sensitive data and critical operations.
In the context of Zero Internet, the primary concept revolves around
the proactive blocking of a significant portion, usually about 99.99
percent, of incoming connections to or from the Internet, especially
those associated with unknown websites. Instead, only connections
to a predefined and restricted set of trusted destinations, typically
limited to around 100 or fewer, are permitted. Although this
approach may appear extreme, it is a crucial safeguard against the
constantly evolving threats posed by AI-driven attacks and
automated systems.
By embracing the Zero Internet concept, organizations can anticipate
and neutralize potential cyber threats before they even materialize.
The proactive blocking of a vast majority of potential attack vectors
ensures that a considerable number of security vulnerabilities are
eliminated at the outset.
The benefits of Zero Internet are manifold. Firstly, it significantly
reduces the exposure to malicious websites, infected domains, and
unverified sources, which are the primary vehicles for malware
distribution and cyber-attacks. Secondly, it allows organizations to gain
better control over their network traffic and mitigate the risk of data
exfiltration. Lastly, it establishes a robust foundation for incident
response and threat management, making it easier to identify and
contain any emerging threats effectively.
