Building BIOS Architecture

Incident Detection identifies events that threaten BIOS integrity, building safety, operational continuity, privacy, or configuration trust.

Incidents may include:

unauthorized access;

malware or compromised service;

credential theft;

configuration tampering;

denial of service;

abnormal command patterns;

identity duplication;

false sensor data;

unauthorized firmware;

physical tampering;

storage corruption;

repeated system failure;

loss of control authority;

unexplained configuration drift.

Detection may use:

authentication logs;

configuration-integrity checks;

network monitoring;

behavioral baselines;

event correlation;

driver and service health;

state inconsistencies;

physical tamper indicators;

dependency analysis;

external security advisories.

Each incident shall be classified by:

type;

severity;

affected scope;

confidence;

physical consequence;

data consequence;

operational consequence;

current containment status.

The incident-response process shall include:

detect;

validate;

classify;

preserve evidence;

contain;

maintain or establish safe physical operation;

revoke or restrict affected authority;

investigate;

remove the cause;

restore trusted software and configuration;

rotate affected credentials;

verify physical and digital states;

recommission affected functions;

monitor for recurrence;

document lessons and corrective actions.

Recovery shall use a verified trusted baseline. Restarting compromised software without removing the cause shall not constitute recovery.

Where physical actions may have occurred during compromise, the building shall be inspected and reconciled rather than assuming that restoration of digital configuration restored the physical state.

Incident closure shall identify:

root cause where known;

affected entities;

timeline;

evidence;

containment actions;

configuration changes;

credentials replaced;

systems recommissioned;

residual risk;

required governance or design changes.
