Vault: Security Automation
Provides the foundation for cloud security that uses trusted sources of identity
to keep secrets and application data secure in the cloud operating model
Secrets management to centrally store and
protect secrets across clouds and applications
Data encryption to keep application data secure
across environments and workloads
Advanced Data Protection to secure workloads
and data across traditional systems, clouds, and
infrastructure.

Vault: Hybrid / Multi-Cloud Security
Secure
Multi Cloud Security
● Hybrid / Multi Cloud
Secrets Management
○ Enables teams to securely
store and tightly control
access to tokens,
passwords, certificates, and
encryption keys for
protecting machines and
application
● EaaS: Encryption as a
Service

Single Control
Plane for cloud
security
● Automate, control, and secure infrastructure and
applications through one API
● Uniﬁed support across heterogeneous
environments
● Integrate with providers and technologies you’re
already using

Vault Agent
VAULT APPROACH TO DYNAMIC INFRASTRUCTURE 12
Vault Agent is a client daemon that provides
the following features:
● Auto-Auth - Automatically authenticate to
Vault and manage the token renewal
process for locally-retrieved dynamic
secrets.
● Caching - Allows client-side caching of
responses containing newly created tokens
and responses containing leased secrets
generated off of these newly created tokens.
● Templating - Allows rendering of user
supplied templates by Vault Agent, using the
token generated by the Auto-Auth step.

Vault Agent
Caching
Vault Agent Caching can cache the tokens
and leased secrets proxied through the
agent which includes the auto-auth token.
This allows for easier access to Vault
secrets for edge applications, reduces
the I/O burden for basic secrets access for
Vault clusters, and allows for secure local
access to leased secrets for the life of a
valid token

Vault Agent
Templates
Vault Agent Templates allows Vault
secrets to be rendered to files using the
Consul Template markup language. This
significantly simplifies the workflow
when you are integrating your
applications with Vault.

Consul
Provides a foundation of cloud network automation using a shared registry for
service based networking
50k+
Used at scale with
50k+ agents
1M+
Monthly D/Ls
Service registry & health monitoring to provide a
real-time directory of all services with their health status
Network middleware automation with service discovery
for dynamic reconfiguration as services scale up, down or
move
Zero trust network with service mesh to secure
service-to-service traffic with identity-based security policies
and encrypted traffic with Mutual-TLS

The Shift from Static to Dynamic Networking
● Modular services with dynamic IPs, running on bare metals, VMs, containers...
● 85% of volume from complex east-west traﬃc*
● No clear network perimeters

Consul: Hybrid / Multi-Cloud Service Networking (MESH)
Connect
Hybrid/Multi Cloud
Service Networking
● Consul provides a hybrid/multi-cloud
service networking layer to connect
and secure services
● Service Registry & Discovery
○ Common service registry
○ Integrated health checks
○ DNS and API interfaces to enable
any service to discover and be
discovered by other services.
● Consistent registry and discovery of
services across multi-data center,
cloud, and platform environments.
● Service Mesh
○ Consul provides a distributed service
mesh to connect, secure, and
configure services across any
runtime platform and cloud.

Consul Connect
Consul Connect provides service-to-service
connection authorization and encryption using
mutual Transport Layer Security (TLS).
Applications can use sidecar proxies in a service
mesh configuration to establish TLS connections
for inbound and outbound connections without
being aware of Connect at all. Applications may
also natively integrate with Connect for optimal
performance and security. Connect can help you
secure your services and provide data about
service-to-service communications.
Secure service-to-service traffic with identity-based
security policies and encrypted traffic with Mutual-TLS

Single Control Plane
for cloud networking
● Automate and control the data plane
with central service registry
● Unified support across
heterogeneous environment
● Simplified operation with single
workflow

Uniﬁed Networking Solution for Hybrid/Multi-Cloud

Vault Replication for Military Systems
Leverage Vault Replication to allow
edge-based warﬁghting systems to perform
secrets management with centralized Vault
environments.
▪ Primary: Source of truth located in central ship
or land-based command operations center.
▪ Secondaries: Located at mobile C2I centers
that can connect directly to edge systems.
▪ Vault Agent: Deployed on edge warﬁghting
systems for local secrets management
operations using K/V.

Mesh Networking with Consul Connect
Using Consul Connect will allow Vault
Agents to route communications to
Vault clusters via the Airborne Network
▪ Allows Vault Agent to sync ad hoc
with Vault performance secondaries
via TTNT, WNW to Airborne Network
routers when available
▪ Minimize round trip delay and provide
additional options for Vault replication

TTNT = Tactical Targeting Network Technology
WNW = Wideband Network Waveform

Secrets Management in
Adverse Conditions
When in periods of reliable/semi-reliable
connectivity, use Consul + Vault Agent
Caching and Templating to reﬂect the active
state of secrets in the primary within ﬁles local
to the edge system.
Vault Agent
(/foo/bar, value_1)
Secondary Cluster
(/foo/bar, value_1)
Primary Cluster
(/foo/bar, value_1)
Reliable/Semi-Reliable Connectivity

Secrets Management in Adverse Conditions
When outside the range of connectivity,
Vault Agent Caching & Templating retains
the last known version of K/V in the linked
ﬁle that references the secret.
This ensures continued access for local
applications at the edge while the
secondary cluster remains disconnected
in the ﬁeld.

(/foo/bar, value_1)
Primary Cluster

Reliable/Semi-Reliable
Connectivity

?

Secrets Management in Adverse Conditions
When TTL expires and/or operator thinks edge
compromised, primary iterates K/V version with
new value
▪ Agent is unable to retrieve an update to their K/V
pair until they re-enter connectivity with a
connected secondary and reauthenticate.
▪ Resilience against compromise of edge system.
Compromises isolated at the edge.
▪ Ensures primary/connected secondaries can still
reference previous K/V pair via previous versions.

V0: (/foo/bar, value_1)

Secrets Management in

When reliable/semi-reliable connectivity
re-established, use Vault Agent Templating and

secrets in the primary within ﬁles local to the
edge system.
