SERVICES / CYBERSECURITY & IDENTITY

Design security into the systems your organization relies on.

Security architecture, zero trust, identity, API security, threat modeling and secure delivery.

IN PRACTICE

The work behind the outcome

Map the exposure

Identify internet-facing services, privileged routes, sensitive data paths and trust boundaries before selecting controls.

Design enforceable policy

Define inbound and east-west flows, ownership, default-deny rules, exceptions and a process for testing change.

Prove the control

Test allowed and denied paths, verify telemetry reaches monitoring, and review rules against actual application behavior.

ANIMATED DELIVERY PATH

How the work moves from insight to action

An animated view of the major decision points. Each stage produces evidence for the next.

Discover

Map assets, identities and exposed paths.

Model

Make trust boundaries and traffic flows visible.

Enforce

Apply identity, firewall and API policy.

Observe

Correlate telemetry and test control behavior.

Respond

Contain impact and restore trusted service.

REFERENCE PATTERNS

Security architecture, illustrated

These reference patterns show where firewall rules, segmentation and access decisions can be enforced. Actual design depends on your network, applications and risk assessment.

01 / Internet-facing applicationFilter at the edge, isolate the public tier, and limit access to data.

InternetUntrusted requests

→TLS

WAF + edge firewallWeb rules · rate limits

→Allowed traffic

DMZ / reverse proxyPublic entry point

→Specific ports

App firewallExplicit allow rules

→

App + data tiersPrivate segments

Deny unused inbound paths. Send WAF, firewall and application events to monitoring; review rules and exceptions regularly.

02 / Internal segmentationSeparate workloads and make east-west access intentional.

User zoneWorkstations

→Approved app access

Internal firewallIdentity · service · port policy

→Only required flows

Application zoneServices and APIs

→Restricted service

Data firewallLeast privilege

→

Data zoneSensitive records

✕ Direct workstation-to-database access and unnecessary lateral traffic are blocked.

03 / Identity-aware accessCheck each request before it reaches a protected application.

→Scoped session

ApplicationPrivate resource

Record the decision and session activity. Re-evaluate access when context changes and restrict tool or API permissions to the task.

Conceptual patterns informed by CISA network segmentation guidance and NIST SP 800-207.

INTERACTIVE STORY

How a ransomware attack unfolds

Follow a simplified ransomware scenario and see how layered controls can interrupt it. Use the controls to move through the story.

⚠ATTACK STAGE / 01

Entry

A malicious message or exposed access path reaches a user.

OBSERVED SIGNALSuspicious link · new device

✓DEFENSIVE RESPONSE

Interrupt the attack path

Filter mail and web traffic, use phishing-resistant MFA, and remove unused remote access.

CONTROL OUTCOMEDelivery blocked or identity challenged

⚠ATTACK STAGE / 02

Execution

Untrusted code attempts to run on an endpoint.

OBSERVED SIGNALUntrusted process · script launch

✓DEFENSIVE RESPONSE

Interrupt the attack path

Harden endpoints, restrict privileges, and use detection with rapid host isolation.

CONTROL OUTCOMEProcess stopped and host isolated

⚠ATTACK STAGE / 03

Spread

The attacker looks for credentials and reachable systems.

OBSERVED SIGNALCredential access · network scan

✓DEFENSIVE RESPONSE

Interrupt the attack path

Segment networks, deny unnecessary east-west traffic, and monitor unusual access.

CONTROL OUTCOMELateral path denied at firewall

⚠ATTACK STAGE / 04

Encryption

Files and services may become unavailable.

OBSERVED SIGNALMass file change · service failure

✓DEFENSIVE RESPONSE

Interrupt the attack path

Protect offline or immutable backups and test restoration against recovery objectives.

CONTROL OUTCOMEProtected copies remain recoverable

⚠ATTACK STAGE / 05

Response

The team contains the incident and restores trusted operations.

OBSERVED SIGNALConfirmed scope · evidence preserved

✓DEFENSIVE RESPONSE

Interrupt the attack path

Isolate affected systems, preserve evidence, investigate scope, and restore in a controlled order.

CONTROL OUTCOMETrusted service restored in sequence

Step 1 of 5

Illustrative scenario. Incident actions depend on your environment and response plan.

DELIVERABLES

What you can expect

An engagement shaped around your environment, priorities and decision points.

01Current-state risk and control map

02Prioritized remediation roadmap

03Architecture decisions and implementation guidance

ENGAGEMENT

A practical way forward

We begin by confirming goals, constraints and existing evidence. From there, we define a focused scope, review the current state and provide decisions your team can act on.
