TL;DR
Cyber security and AI security overlap but are distinct: cyber security protects networks and data, while AI security defends models, datasets, and inference pipelines. This post explains key threats, concrete controls, and a five-step operational plan so teams can reduce risk quickly.

Introduction
Malicious actors target both infrastructure and AI systems, and failures in either realm can expose sensitive data, corrupt decisions, or enable large-scale fraud; addressing both is now a core business risk.
Cyber Security and AI security, Defined
Cyber security secures systems, networks, and data; AI security secures models, training data, and inference pipelines.
Cyber security includes network defence, identity, and endpoint protection. AI security covers dataset integrity, model robustness, supply-chain risks, model extraction and poisoning, and secure deployment practices.
The Case for Cyber Security and AI security
Protecting AI systems matters because compromised models or poisoned data can produce wrong decisions at scale, amplifying harm beyond a single breach.
Organizations that ignore AI-specific risks inherit new attack surfaces: model theft, data poisoning, adversarial inputs, and stealthy model manipulation can bypass traditional perimeter controls and regulatory expectations.
The Part Nobody Mentions
Hardening infrastructure often costs less and delivers clearer ROI than perfecting model robustness; the trade-off depends on where the organization stores data and how critical model outputs are to business decisions.
The choice between investing in traditional cyber defences versus AI-specific controls hinges on data sensitivity, model criticality, and operational scale — which one to prioritise depends on those business parameters and risk appetite.
Putting Cyber Security and AI security Into Practice
Start with a risk-tiered approach: classify models and data, apply standard cyber controls to infrastructure, then add AI-specific protections where model impact or data sensitivity is high.
Step 1 — Classify models and data
Identify which models and datasets are high-risk and assign tiers (e.g., Tier 1: safety/finance/identity; Tier 2: user experience; Tier 3: experimental).
Why: Triage lets teams apply scarce controls where they reduce the most harm. How: map each model to business impact, data sensitivity, and exposure (public API, internal service, edge device).
Step 2 — Apply baseline cyber controls
Ensure network segmentation, strong identity and access management, encryption in transit and at rest (TLS 1.2+; AES-256 for data at rest), and endpoint protections.
Why: Many AI incidents start with stolen credentials or lateral movement. How: enforce least privilege, use MFA for developer and service accounts, and log authentication events centrally.
Step 3 — Harden the ML supply chain
Verify third-party models and data sources, pin dependency versions, and run SBOMs for model artifacts and libraries.
Why: Pretrained models and open datasets can carry backdoors or licensing issues. How: require provenance metadata, reproducible builds, and cryptographic signing of released model artifacts.
Step 4 — Monitor models in production
Instrument model inputs and outputs for drift, distribution shifts, adversarial patterns, and unexplained performance changes.
Why: Early detection limits damage from data poisoning or targeted adversarial campaigns. How: capture feature distributions, latency anomalies, confidence shifts, and set alert thresholds for sudden deviations.
Step 5 — Implement containment and recovery playbooks
Prepare rollback plans, canary deployments, and isolation procedures for compromised models or data pipelines.
Why: Incidents will happen; fast containment reduces impact. How: keep cold backups of verified models, automate canary promotion, and document runbooks for revoking model access and re-training from clean data.
Frequently Asked Questions
Is AI security the same as cyber security?
No. AI security overlaps with cyber security but adds model-level risks like poisoning, extraction, and adversarial attacks that require different controls.
Cyber security secures systems and data; AI security secures the training data, model integrity, and inference behaviour specifically.
Can traditional security controls stop model extraction attacks?
Not on their own. Network and IAM controls help, but model extraction often exploits exposed prediction APIs and requires rate-limiting, output minimisation, and monitoring too.
Mitigations include response-rate limits, adding noise to non-critical outputs, requiring stronger authentication for sensitive endpoints, and logging suspicious query patterns.
How should organizations prioritise investments between cyber and AI security?
Prioritise by impact: protect high-tier models and sensitive datasets first, then raise baseline cyber hygiene across teams.
Assess model criticality, external exposure, and regulatory obligations to decide whether to focus on infrastructure, supply chain, or model hardening first.
Are there standards to follow for AI security?
Yes. Use established frameworks such as NIST's AI Risk Management guidance and established cyber standards like ISO/IEC 27001 and MITRE ATT&CK for threat mapping.
Standards help translate governance into controls and provide terminology for risk conversations with auditors and leadership.
What quick wins reduce AI security risk immediately?
Enforce MFA for model-serving accounts, require signed model artifacts, enable logging for inference endpoints, and adopt automated alerts for distribution drift.
Those controls reduce the most common attack vectors without massive tooling spend and provide early detection capability.

Start Here
Inventory the organisation's AI assets and map them to business impact; treat that inventory as the single source of truth for prioritisation.
- Run an inventory: list models, owners, data sources, exposure (public/internal), and business impact.
- Check access: confirm all model-serving and data accounts have MFA and least-privilege roles.
- If inventory is missing, start by tagging the top three models that influence money, safety, or compliance.
After the inventory, implement one containment playbook for the most exposed model and schedule a model-monitoring pipeline within 30 days.
