Introduction:
LARVOL’s presentation at ASCO 2026—Evaluating AI Decision Support in a Rapidly Evolving Therapeutic Landscape: EGFR-Mutant Metastatic NSCLC—represents a high‑water mark for clinical AI adoption. While AI models like LARVOL CLIN and VERI accelerate precision oncology, they also introduce novel attack surfaces: adversarial inputs, model poisoning, and API‑driven data exfiltration. Securing these systems is not an afterthought but a prerequisite for patient safety and regulatory compliance.
Learning Objectives:
- Understand how AI decision‑support systems for EGFR‑mutant NSCLC process multimodal data (imaging, genomics, clinical notes).
- Identify the unique cybersecurity risks facing clinical AI, including model inversion, data poisoning, and supply‑chain attacks.
- Apply platform‑specific hardening commands, API security controls, and cloud governance to protect an AI‑driven oncology workflow.
You Should Know
- Hardening LARVOL‑Like AI Pipelines: Linux & Windows Security Controls
AI platforms such as LARVOL CLIN ingest real‑time clinical trial data, conference abstracts, and KOL feeds. Attackers could poison this ingestion layer. Below are verified commands to secure the underlying infrastructure.
Linux (Ubuntu 22.04 LTS)
Harden SSH and disable root login sudo sed -i 's/PermitRootLogin yes/PermitRootLogin no/' /etc/ssh/sshd_config sudo systemctl restart sshd Set strict iptables rules – allow only necessary ports (e.g., 443, 22) sudo iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT sudo iptables -A INPUT -p tcp --dport 22 -j ACCEPT SSH sudo iptables -A INPUT -p tcp --dport 443 -j ACCEPT HTTPS sudo iptables -P INPUT DROP sudo iptables -P FORWARD DROP sudo apt install iptables-persistent
Windows Server 2022 (PowerShell as Administrator)
Enable Windows Defender Advanced Threat Protection Set-MpPreference -DisableRealtimeMonitoring $false Set-MpPreference -PUAProtection Enabled Restrict inbound RDP to a specific IP range New-1etFirewallRule -DisplayName "Restrict RDP" -Direction Inbound -Protocol TCP ` -LocalPort 3389 -RemoteAddress 192.168.1.0/24 -Action Allow
Step‑by‑Step Hardening Guide for an AI Data Ingestion Node:
1. Minimize the attack surface – remove unused services (`systemctl disable cupson Linux; `Remove-WindowsFeature Web-Server` on Windows).sudo apt install lynis; sudo lynis audit system`.
2. Enforce mandatory access control – on Linux install AppArmor or SELinux; on Windows configure Windows Defender Application Control (WDAC).
3. Enable filesystem integrity monitoring – `sudo apt install aide` and initialise the database.
4. Schedule regular vulnerability scans –
5. Verify log integrity – forward logs to a remote SIEM using `rsyslog` (Linux) or `nxlog` (Windows).
- Securing FHIR & Clinical Trial APIs Against Injection and Rate‑Limiting Attacks
LARVOL’s platform aggregates clinical trial data from sources like ClinicalTrials.gov and EudraCT. These integrations often use REST APIs with HL7/FHIR payloads. Without proper controls, attackers can inject malicious queries or overwhelm the API with traffic.
API Gateway Hardening (Example using Kong + Nginx)
Nginx rate‑limiting for API endpoints
limit_req_zone $binary_remote_addr zone=clinapi:10m rate=10r/s;
location /api/v1/clinicaltrials {
limit_req zone=clinapi burst=20 nodelay;
proxy_pass http://backend_clin;
}
Validate Input to Prevent Injection (Python snippet for FHIR bundles)
import json
from fhir import FHIRValidator
def validate_fhir_bundle(payload):
try:
bundle = json.loads(payload)
Use a strict schema validator
FHIRValidator.validate(bundle, resource_type="Bundle")
except Exception as e:
raise ValueError("Invalid FHIR payload") from e
Step‑by‑Step API Security Implementation:
- Authenticate every request – implement OAuth2 or mutual TLS (mTLS) between LARVOL and data providers.
- Apply schema validation – reject any JSON that does not conform to the FHIR standard.
- Enable audit logging – record API caller identity, timestamp, and payload hash for forensic use.
- Deploy a WAF – use ModSecurity (open source) or a cloud WAF to block SQL/NoSQL injection attempts.
- Set up anomaly detection – monitor for sudden spikes in data access (possible data exfiltration).

Cloud Hardening for AI Training & Inference (Azure / AWS)
LARVOL’s VERI platform and CLIN app run on cloud infrastructure. Protecting the data lake and model endpoints requires a zero‑trust approach.
Azure CLI Commands
Enable Azure Defender for Containers az security pricing create -1 Containers --tier standard Restrict network access to the AI model endpoint az storage account update --1ame larvolmodelstore --default-action Deny az storage account network-rule add --1ame larvolmodelstore --ip-rule "192.168.0.0/24"
AWS CLI Commands
Enforce bucket encryption and block public access
aws s3api put-bucket-encryption --bucket larvol-ai-models \
--server-side-encryption-configuration '{"Rules":[{"ApplyServerSideEncryptionByDefault":{"SSEAlgorithm":"AES256"}}]}'
aws s3api put-public-access-block --bucket larvol-ai-models \
--public-access-block-configuration BlockPublicAcls=true,IgnorePublicAcls=true,BlockPublicPolicy=true,RestrictPublicBuckets=true
Step‑by‑Step Cloud Governance for Clinical AI:
- Adopt a zero‑trust architecture – verify every request, regardless of origin.
- Implement data classification – tag all NSCLC‑related datasets as “restricted.”
- Use private endpoints for model training buckets – no public IP exposure.
- Automate drift detection with AWS Config or Azure Policy to prevent accidental misconfigurations.
- Rotate encryption keys – set a 90‑day rotation policy for KMS keys used for AI models.

Countering AI‑Specific Threats: Adversarial Robustness & Model Monitoring
AI models for EGFR mutation prediction, like LG‑MutaNet, can be fooled by adversarial perturbations. Attackers could add imperceptible noise to a CT image, causing the model to misclassify a malignant tumour as benign.
Defence: Adversarial Training with Foolbox
import foolbox as fb
import torch
model = torch.load("egfr_model.pt")
fmodel = fb.PyTorchModel(model, bounds=(0,1))
attack = fb.attacks.LinfPGD()
Generate adversarial examples and retrain
_, adv_images, _ = attack(fmodel, images, labels, epsilons=[0.03])
Augment training set with adversarial samples
Operational Monitoring
- Model input validation – reject images with unexpected noise patterns (e.g., high‑frequency components).
- Output confidence monitoring – flag predictions that flip abruptly after small input changes.
- Continuous retraining – periodically update the model with clean, vetted data to wash out poisoned samples.
Step‑by‑Step Model Hardening:
- Evaluate base robustness – run a red‑team adversarial attack suite.
- Apply input sanitisation – normalise DICOM images before inference.
- Enforce cryptographically signed model updates – only load models with a valid signature.
- Isolate inference endpoints – run them in a separate security zone from training infrastructure.
- Log all inference requests – retain logs for at least 12 months for post‑incident analysis.

Training & Certification: AI Security for Oncology Professionals
To bridge the gap between clinical AI and cybersecurity, dedicated training courses are available. The “Certified AI in Medical Devices & Diagnostics (CAIMDD)” covers threat modelling, secure ML engineering, and PHI protection. The “Digital Health and Artificial Intelligence in Healthcare Essentials” from CISA focuses on implementing AI while protecting patient data.
Recommended Curriculum for LARVOL Engineers:
- Module 1: Model Threat Modelling – use STRIDE to identify AI‑specific threats.
- Module 2: Secure API and FHIR Integration – hands‑on labs with OAuth2 and mTLS.
- Module 3: Cloud Security for Healthcare AI – scenario‑based training on Azure/AWS governance.
- Module 4: Incident Response for Compromised Models – practice rollback and forensic analysis.
Linux Command to Scan for Open Model Endpoints:
nmap -p 8501,8080,5000 --open 10.0.0.0/24 | grep "Nmap scan report" > model_endpoints.txt
This helps discover unlisted inference endpoints that might have been spun up without proper security controls.
What Undercode Say
- Key Takeaway 1: Clinical AI adoption (like LARVOL’s NSCLC decision support) cannot outpace security maturity. Adversarial attacks and data poisoning are not theoretical—they are being actively researched and demonstrated.
- Key Takeaway 2: Hardening must happen at every layer: the OS, the API gateway, the cloud environment, and the model itself. A single misconfigured S3 bucket or an unvalidated FHIR payload can compromise the entire pipeline.
Analysis:
The healthcare sector has historically prioritised availability over confidentiality, but AI changes the risk calculus. A corrupted AI model can cause systematic harm—misdiagnosing hundreds of patients before anyone notices. LARVOL’s use of “expert curation combined with NLP” mitigates some risks by adding a human‑in‑the‑loop, but automated ingestion and API integrations remain vulnerable. Organisations must adopt a zero‑trust security model, invest in adversarial robustness testing, and train both clinical and IT staff on AI‑specific threats. The cost of a breach is no longer just data exfiltration—it is patient lives.
Prediction
- +1 AI decision support for EGFR‑mutant NSCLC will become standard of care within 36 months, driven by platforms like LARVOL CLIN, as regulators approve “locked‑down” clinical AI appliances with hardware‑level security.
- +1 The market for AI security training specific to healthcare will grow 400% by 2029, with certifications like CAIMDD becoming mandatory for oncology data scientists.
- -1 Without widespread adoption of API‑level threat detection, a major healthcare AI provider will suffer a model‑poisoning attack before 2028, leading to temporary suspension of clinical AI use in at least two countries.
- -1 Cloud misconfiguration in AI training pipelines will remain the leading cause of PHI exposure; a large oncology AI dataset will be leaked due to a publicly accessible S3 bucket within the next 18 months.
- +1 Federated learning and confidential computing (e.g., Azure Confidential VMs) will emerge as the de facto standard for multi‑institutional clinical AI, eliminating the need to centralise sensitive data and drastically reducing the attack surface.
