<h3>The Challenge</h3>
|
||
<span class='sub-heading'>Securing service-to-service communication with firewalls doesn’t scale in dynamic settings.</span>

<div id='segmentation-challenge-animation' class='g-animation-block'>
|
||
<%= inline_svg 'consul-connect/svgs/segmentation-challenge.svg' %>
|
||
</div>
|
||
<p>East-west firewalls use IP-based rules to secure ingress and
|
||
egress traffic. But in a dynamic world where services move across
|
||
machines and machines are frequently created and destroyed, this
|
||
perimeter-based approach is difficult to scale as it results in
|
||
complex network topologies and a sprawl of short-lived
|
||
firewall rules.</p>
|
||
</div>

<div>

<h3>The Solution</h3>
|
||
<span class='sub-heading'>Service segmentation for dynamic service authorization.</span>
|
||
<div id='segmentation-solution-animation' class='g-animation-block'>
|
||
<%= inline_svg 'consul-connect/svgs/segmentation-solution.svg' %>
|
||
</div>
|
||
<p>Service segmentation is a new approach to secure the service itself
|
||
rather than relying on the network. Consul uses service policies to
|
||
codify which services are allowed to communicate. These policies
|
||
scale across datacenters and large fleets without IP-based rules or
|
||
networking middleware.</p>

<h3>Service Access Graph </h3>

<p>Define and enforce service to service communication with a simple Intentions configuration. Service based rules, instead of IP-based rules, make it easy to manage dynamic infrastructure with frequently changing machines and service locations.</p>

<h3>Certificate-Based Service Identity</h3>
|
||
<p>TLS certificates are used to identify services and secure communications. Certificates use the SPIFFE format for interoperability with other platforms. Consul can be a certificate authority to simplify deployment, or integrate with external signing authorities like Vault.</p>

<h3>Encrypted communication</h3>
|
||
<p>All traffic between services is encrypted and authenticated with mutual TLS. Using TLS provides a strong guarantee of the identity of services communicating, and ensures all data in transit is encrypted.</p>
