You Should Know:

1. The HPC-AI Convergence: A New Attack Surface

HKUST(GZ) operates one of the most advanced HPC-AI converged computing centers in Asia, featuring four major clusters with a combined computing power exceeding 1,000 Pflops@FP16. This isn’t just about raw power; it’s about the convergence of high-performance computing and AI acceleration, which introduces unique vulnerabilities. The center integrates multi-1ode/multi-GPU collaboration, unified heterogeneous resource management, and high-speed networks like 400Gb/s RoCE v2. For security professionals, this means traditional perimeter defenses are obsolete. Attackers can now target the AI training pipeline, poison datasets, or exploit the InfiniBand and RoCE networks to intercept sensitive model weights.

Step‑by‑Step Guide: Auditing an HPC-AI Environment

  1. Network Mapping: Identify all active nodes and services. On Linux, use `nmap -sS -p- -T4 ` to scan for open ports on compute nodes. On Windows, use `Test-1etConnection -ComputerName -Port ` to check specific service availability.
  2. GPU Resource Monitoring: Check for unauthorized GPU access. On Linux with NVIDIA GPUs, run `nvidia-smi` to list active processes and GPU memory usage. Look for unknown processes consuming GPU resources – a potential sign of cryptojacking or model theft. Use `ps -ef | grep python` to identify running AI training scripts.
  3. Network Traffic Analysis: Monitor east-west traffic within the cluster. Use `tcpdump -i ib0 -w hpc_traffic.pcap` on InfiniBand interfaces to capture packets. Analyze with Wireshark or `tshark -r hpc_traffic.pcap -Y “ib”` to detect anomalous data exfiltration patterns.
  4. Container Security Scan: If using Docker or Kubernetes for AI workloads, scan images for vulnerabilities. Run `docker scan ` (requires Snyk) or `trivy image ` to identify known CVEs in the base images.
  5. Access Log Review: Audit SSH and API access logs. On Linux, check `/var/log/auth.log` and `/var/log/syslog` for failed login attempts. On Windows, use `Get-WinEvent -LogName Security | Where-Object { $_.ID -in @(4624,4625) }` to filter successful and failed logon events.

2. AI Security and Adversarial Machine Learning

The Security Research Lab at HKUST(GZ) is laser-focused on advancing secure and privacy-preserving sensing and computation to protect “ground-breaking AI and cyber-physical technologies”. This is critical because AI models are inherently vulnerable to adversarial attacks – subtle perturbations in input data that cause misclassification. The lab’s research spans software and AI security, embodied AI security, electromagnetic and sensing security, and AI for security. For practitioners, this means developing robust defenses against model extraction, data poisoning, and inference attacks.

Step‑by‑Step Guide: Implementing Adversarial Defenses

  1. Install Adversarial Robustness Toolbox (ART): On Linux or Windows (with Python 3.8+), run pip install adversarial-robustness-toolbox. This library provides state-of-the-art defenses.
  2. Load a Pre-trained Model: Use TensorFlow or PyTorch. Example: model = tf.keras.applications.ResNet50(weights='imagenet').
  3. Generate Adversarial Example (FGSM Attack): Use ART’s Fast Gradient Sign Method. Code snippet: 
    from art.attacks.evasion import FastGradientMethod
attack = FastGradientMethod(estimator=classifier, eps=0.05)
adversarial_samples = attack.generate(x_test)
  4. Apply Defensive Distillation: Train a distilled model to reduce sensitivity to input perturbations. Use ART’s classifier = TensorFlowV2Classifier(model=distilled_model, ...).
  5. Implement Input Validation: Add a preprocessing layer that checks for statistical anomalies. On Linux, use `scipy.stats` to compute z-scores of input features and reject outliers beyond a threshold (e.g., |z| > 3).
  6. Monitor Model Drift: Set up a pipeline to continuously evaluate model accuracy on a held-out validation set. If accuracy drops below a threshold (e.g., 5% degradation), trigger an alert. Use `sklearn.metrics.accuracy_score` for evaluation.

3. Data-Centric AI and Privacy-Preserving Computation

HKUST(GZ) offers Asia’s first MSc program in Data-Centric Artificial Intelligence Technology (MSc DCAI), featuring a dual supervision system and a year-long industry internship. This program emphasizes the shift from model-centric to data-centric AI – focusing on data quality, labeling, and privacy. With the rise of federated learning and differential privacy, securing data at rest and in transit is paramount. The university’s curriculum includes courses on “Data Mining and Knowledge Discovery,” “Advanced Database Management,” and “Cloud Computing and Big Data Systems”.

Step‑by‑Step Guide: Implementing Differential Privacy

  1. Install PyTorch or TensorFlow Privacy: On Linux, run pip install tensorflow-privacy. On Windows, use the same command in a Python virtual environment.
  2. Define a DP-SGD Trainer: Use the `DPKerasSGDOptimizer` from TensorFlow Privacy. Example: 
    from tensorflow_privacy.privacy.optimizers.dp_optimizer_keras import DPKerasSGDOptimizer
optimizer = DPKerasSGDOptimizer(l2_norm_clip=1.0, noise_multiplier=0.5, num_microbatches=256, learning_rate=0.15)
model.compile(optimizer=optimizer, loss='categorical_crossentropy')
  3. Compute Privacy Budget: Use the `compute_dp_sgd_privacy` function to calculate epsilon (ε) and delta (δ) based on the number of epochs and batch size.
  4. Implement Federated Learning: Use TensorFlow Federated (TFF) to simulate a federated learning environment. On Linux, pip install tensorflow-federated. Define a federated averaging process and ensure secure aggregation using encryption.
  5. Encrypt Data at Rest: On Linux, use `gpg -c ` to symmetrically encrypt sensitive datasets. On Windows, use `cipher /E ` to encrypt files using the Encrypting File System (EFS).
  6. Secure API Endpoints: For data access APIs, implement OAuth 2.0 with JWT tokens. Use `flask-jwt-extended` in Python. Example: 
    from flask_jwt_extended import create_access_token
access_token = create_access_token(identity=user_id)

4. IoT and Cyber-Physical Systems Security

The IoT Thrust at HKUST(GZ) is a academic department specializing in communications, networking, machine learning, IoT sensors, embedded systems, and cybersecurity. With 27 full-time faculty members publishing in top venues like SIGCOMM, CCS, and INFOCOM, the thrust is at the forefront of securing the Internet of Things. Cyber-physical systems (CPS) – which integrate computation, networking, and physical processes – are particularly vulnerable to attacks that can have real-world consequences, from smart grid failures to autonomous vehicle hijacking.

Step‑by‑Step Guide: Securing IoT/CPS Devices

  1. Firmware Analysis: Extract and analyze device firmware. On Linux, use `binwalk -e ` to extract embedded file systems. Look for hardcoded credentials or backdoors.
  2. Vulnerability Scanning: Use `nmap` with NSE scripts to scan IoT devices. Example: nmap -sV --script vuln <DEVICE_IP>.
  3. Network Segmentation: Isolate IoT devices on a separate VLAN. On Linux, use `vconfig` to create VLAN interfaces. On Windows, use PowerShell: New-1etLbfoTeam -1ame "IoTTeam" -TeamMembers "Ethernet1","Ethernet2".
  4. Implement MQTT Security: If using MQTT for device communication, enable TLS. On Linux, configure Mosquitto with `listener 8883` and cafile /etc/mosquitto/ca_certificates/ca.crt.
  5. Device Authentication: Use X.509 certificates for device identity. Generate a self-signed certificate: openssl req -x509 -1ewkey rsa:2048 -keyout device.key -out device.crt -days 365 -1odes.
  6. Monitor for Anomalies: Set up a SIEM (e.g., Splunk or ELK Stack) to ingest logs from IoT devices. Create alerts for unusual traffic patterns, such as a device sending data at odd hours.

5. High-Performance Computing Security Hardening

With HKUST(GZ)’s HPC clusters delivering industry-leading computational density, securing these environments is non-1egotiable. The clusters use a mix of Intel CPU nodes, AMD CPU nodes, and NVIDIA GPUs (A30, A800, A40), interconnected via InfiniBand and RoCE networks. Security measures must address both the compute nodes and the storage systems (which include parallel file systems and hybrid storage architectures).

Step‑by‑Step Guide: Hardening an HPC Cluster

  1. Disable Unnecessary Services: On each compute node (Linux), run `systemctl list-unit-files –type=service –state=enabled` to list all enabled services. Disable services like cups, bluetooth, and `avahi-daemon` using systemctl disable <SERVICE>.
  2. Implement SSH Key-Based Authentication: Disable password authentication. Edit `/etc/ssh/sshd_config` and set `PasswordAuthentication no` and PubkeyAuthentication yes. Restart SSH: systemctl restart sshd.
  3. Set Up a Jump Host: Use a bastion host as the single entry point to the cluster. Configure `ssh` to proxy through the jump host: ssh -J user@bastion_ip user@compute_node.
  4. Audit SUID/SGID Binaries: On Linux, find all SUID/SGID binaries: find / -perm -4000 -o -perm -2000 -type f 2>/dev/null. Remove unnecessary SUID bits using chmod u-s <FILE>.
  5. Implement SELinux or AppArmor: Enforce mandatory access control. On RHEL/CentOS, set SELinux to enforcing mode: `setenforce 1` and edit /etc/selinux/config.
  6. Storage Encryption: For NFS or parallel file systems, enable encryption in transit. On Linux, use `mount -o vers=4.2,sec=krb5p :/export /mnt` to mount with Kerberos privacy.
  7. Regular Vulnerability Scanning: Use OpenVAS or Nessus to scan the cluster. Install OpenVAS on Linux: `apt-get install openvas` and run openvas-setup.

6. Cloud Security and API Hardening

HKUST(GZ)’s curriculum includes courses on “Cloud Computing and Big Data Systems,” reflecting the industry’s shift to cloud-1ative architectures. Securing cloud environments and APIs is a critical skill for IT professionals. The university’s training center also offers professional development in digital technology, big data, and AI, covering security management and operations.

Step‑by‑Step Guide: Cloud and API Security

  1. API Gateway Configuration: Use Kong or AWS API Gateway to enforce rate limiting and authentication. On Linux, install Kong: curl -s https://get.konghq.com/install.sh | sh. Define a service and route, then enable key-auth plugin.
  2. Implement OAuth 2.0: Use Keycloak or Okta. On Linux, deploy Keycloak using Docker: docker run -p 8080:8080 -e KEYCLOAK_USER=admin -e KEYCLOAK_PASSWORD=admin quay.io/keycloak/keycloak:latest.
  3. Cloud Security Posture Management (CSPM): Use tools like Prowler or ScoutSuite. On Linux, install Prowler: pip install prowler. Run `prowler aws` to audit AWS environments.
  4. Container Security: Use Kubernetes with Pod Security Policies (PSP) or OPA Gatekeeper. Example PSP: apiVersion: policy/v1beta1; kind: PodSecurityPolicy; metadata: name: restricted; spec: privileged: false.
  5. Secrets Management: Use HashiCorp Vault. On Linux, install Vault: `wget https://releases.hashicorp.com/vault/…`. Start Vault in dev mode: `vault server -dev`.
  6. Cloud Firewall Rules: On AWS, use Security Groups to restrict inbound traffic. On Azure, use Network Security Groups (NSGs). On Linux, use `iptables` to set up a basic firewall: `iptables -A INPUT -p tcp –dport 22 -j ACCEPT` and iptables -A INPUT -j DROP.
