Control PlanCP-02Live Incident Containment
A breach is live. Which path can you disconnect without stopping everything?
During a live incident, the response team needs a prepared way to withdraw selected connections from an affected segment, site or service. CP-02 defines those connections, who may authorise the action and what must keep working.

What is at stake
Why live incident containment matters.
A broad shutdown can turn a local incident into an operational crisis, while waiting can leave the affected route available. The decision is easier when the boundary and its consequences are agreed before the incident.
The problem today
Where you are IP connected today.
CP-02 reviews four IP-connected paths in your business. While a path stays connected over IP, it is a route that can be reached, misused or exploited. Each path below carries its own risk to agree with its owner.
- Risk 1Affected user segment uplinks
All agreed physical uplinks between one user segment and the core network.
Whenever this path is open over IP, it is a route that can be reached, misused or exploited.
Agreed state: Connected for normal service
- Risk 2Remote access inside interface
The connection from the remote access service into internal networks.
Whenever this path is open over IP, it is a route that can be reached, misused or exploited.
Agreed state: Connected for approved users
- Risk 3Privileged management path
Administrator access from approved workstations to server, storage and network management.
Whenever this path is open over IP, it is a route that can be reached, misused or exploited.
Agreed state: Disconnected outside approved windows
- Risk 4Site to site link
Selected links between offices, sites or plants, including agreed failover routes.
Whenever this path is open over IP, it is a route that can be reached, misused or exploited.
Agreed state: Connected for normal service
What Firevault changes
What changes with this Plan.
Withdraw selected connections from an affected area on an authorised decision, while keeping unaffected services available where their dependencies allow.
| Connection | Agreed normal state | Control action |
|---|---|---|
| Affected user segment uplinks | Connected for normal service | Validate checks the rule or authority. Execute initiates the action. Isolate groups the uplinks and Fracture withdraws them. |
| Remote access inside interface | Connected for approved users | Validate checks authority. Execute initiates the action. Fracture withdraws the inside connection. |
| Privileged management path | Disconnected outside approved windows | Validate checks the request. Execute opens or closes the path. Fracture withdraws it at the end of the window. |
| Site to site link | Connected for normal service | Validate checks authority. Execute initiates the action. Isolate groups agreed links and Fracture withdraws them. |
CP-02 does not detect incidents, remove malware, recover systems or control activity that never crosses a registered connection. Cloud identity, SaaS and independent cellular devices need their own response measures.

The modules involved
The Control modules behind this Plan.
Confirms that the request comes from an authorised incident owner or an agreed high-confidence response rule. Initiates the approved action on the designated connection. Physically withdraws the selected connection. Treats the defined uplinks for a segment, site or zone as one controlled boundary.

Each selected connection, written down.
Withdraw selected connections from an affected area on an authorised decision, while keeping unaffected services available where their dependencies allow.
Affected user segment uplinksAll agreed physical uplinks between one user segment and the core network.Connected for normal service
- Normal state
- Connected for normal service
- Authorisation
- Tier 1: a high-confidence alert matching an agreed rule, or Tier 2: incident owner authorisation
- Module action
- Validate checks the rule or authority. Execute initiates the action. Isolate groups the uplinks and Fracture withdraws them.
- Business effect
- Devices on that segment lose the selected network access. Confirm telephony, wireless and shared service dependencies before approval.
- Failure behaviour
- Behaviour agreed and tested for loss of power or command route.
Remote access inside interfaceThe connection from the remote access service into internal networks.Connected for approved users
- Normal state
- Connected for approved users
- Authorisation
- Tier 2: incident owner authorisation when session revocation is insufficient
- Module action
- Validate checks authority. Execute initiates the action. Fracture withdraws the inside connection.
- Business effect
- Remote users using this route are disconnected until reconnection is approved.
- Failure behaviour
- Behaviour agreed and tested for loss of power or command route.
Privileged management pathAdministrator access from approved workstations to server, storage and network management.Disconnected outside approved windows
- Normal state
- Disconnected outside approved windows
- Authorisation
- Approved work opens the path. An active incident keeps it closed unless the incident owner approves recovery work.
- Module action
- Validate checks the request. Execute opens or closes the path. Fracture withdraws it at the end of the window.
- Business effect
- Administrators use approved windows rather than a standing route.
- Failure behaviour
- Remains disconnected unless an agreed recovery procedure is followed.
Site to site linkSelected links between offices, sites or plants, including agreed failover routes.Connected for normal service
- Normal state
- Connected for normal service
- Authorisation
- Tier 2: incident owner authorisation when activity involves more than one site
- Module action
- Validate checks authority. Execute initiates the action. Isolate groups agreed links and Fracture withdraws them.
- Business effect
- Shared services between sites pause. Each site continues only where local operation has been designed and tested.
- Failure behaviour
- Behaviour agreed with site operations and tested.
CP-02 does not detect incidents, remove malware, recover systems or control activity that never crosses a registered connection. Cloud identity, SaaS and independent cellular devices need their own response measures.
Operational runbook
Who does what, and when.
What happens under normal conditions, during approved work, when an incident is detected and when connections are restored.
Withdraw selected connections from an affected area on an authorised decision, while keeping unaffected services available where their dependencies allow. Each selected connection sits at its agreed normal state.
Set in the Plan, signed off by your operational, security and continuity leads.
Connection states, continuously.
Validate checks the rule or authority. Execute initiates the action. Isolate groups the uplinks and Fracture withdraws them.
Validate
The named owner approves each opening in advance.
Request, approval, opening and closure.
Your security tools raise an alert. The agreed action starts out of band, without depending on the network under attack.
Execute
Pre-authorised in the Plan. The incident owner is told at once.
The alert and the action taken.
Withdraw selected connections from an affected area on an authorised decision, while keeping unaffected services available where their dependencies allow.

Resilience and recovery
Offline Secure Storage®
OSS protects stored business data, recovery copies and retained evidence through physical disconnection. It is a separate storage service, not a Control module or a network containment function.
Control by Firevault governs selected physical connections. Existing detection tools and authorised operators decide when to act. OSS does not detect incidents, command Control or replace operational safety procedures.
Confirm the observed connection state, complete the agreed security and operational checks, then reconnect one approved route at a time.
