Strategies for Managing Engineering Data Security

Industrial Cyber Security—Layer by Layer OT environments can't rely on repackaged IT security checklists. Frameworks like IEC 62443 and NIST SP 800-82 demand a defence-in-depth strategy tailored to physical processes, real-time constraints, and integrated safety systems. This layered defence model visualizes the approach, moving from the physical perimeter to the core data: ✏️ Perimeter Security: Starts with physical controls like site fencing and progresses to network gateways that enforce one-way data flow. ✏️ Network Security: Involves segmenting the network (per the Purdue model), using industrial firewalls, and securing all remote access points. ✏️ Endpoint Security: Focuses on locking down devices with application whitelisting, ensuring secure boot processes, and using anomaly detection to spot unusual behavior. ✏️ Application Security: Secures the software layer through code-signing for logic downloads and hardening engineering workstations. ✏️ Data Security: Protects information itself with encrypted backups, PKI certificates for authenticity, and integrity monitoring. This entire strategy rests on two pillars: 1. Prevention: Proactive measures like architecture reviews, role-based access control (RBAC), and disciplined patch management. 2. Monitoring & Response: OT-aware security operations, practiced incident response playbooks, and the ability to perform forensics on industrial controllers. Why it matters: The data is clear. Over 80% of recent OT incidents exploited weak segmentation or unmanaged assets. Conversely, plants with layered controls have cut their mean-time-to-detect threats by 60% (Dragos 2024). Which of these security rings do you see most neglected in real-world plants? #OTSecurity #IEC62443 #NIST80082 #DefenseInDepth #IndustrialCyber #CriticalInfrastructure #CyberResilience

Dear IT Auditors, Database Audit and Encryption Review Data is only as safe as the encryption that protects it. When encryption controls fail or are poorly implemented, even strong firewalls and access controls cannot stop data exposure. That’s why auditing database encryption processes is a key part of every IT and cybersecurity audit. 📌 Start with the Encryption Policy Begin by reviewing the organization’s data encryption policy. It should define which data must be encrypted, the standards to follow, and the roles responsible for managing encryption keys. Policies that lack detail often lead to inconsistent implementation. 📌 Encryption at Rest Verify that sensitive data stored in databases is encrypted at rest. Review configurations in tools such as Transparent Data Encryption (TDE) for SQL, Oracle, or cloud-managed databases. Ensure encryption algorithms like AES-256 are used rather than weaker ones. 📌 Encryption in Transit Data moving between applications and databases should be encrypted using secure protocols such as TLS 1.2 or higher. Auditors should test whether unencrypted connections (HTTP, FTP, or old JDBC strings) are still in use. Any plaintext transmission is a data leak waiting to happen. 📌 Key Management Controls Strong encryption is meaningless if the keys are weak or mishandled. Review how encryption keys are generated, stored, rotated, and retired. Confirm that keys are held in a secure vault or Hardware Security Module (HSM). Keys should never be hard-coded into scripts or shared via email. 📌 Access to Keys and Certificates Only a limited number of trusted individuals should access encryption keys. Review access lists for key vaults and certificate repositories. Each access should be logged and periodically reviewed. 📌 Backup Encryption Backups often contain full copies of production data. Verify that backup files and storage devices are also encrypted. If backups are sent to third parties or cloud storage, ensure that the same encryption controls are applied. 📌 Decryption and Recovery Testing Encryption isn’t complete without successful decryption. Review whether periodic recovery tests are performed to confirm that encrypted backups and databases can be restored correctly. Unrecoverable encryption is as dangerous as no encryption. 📌 Audit Evidence Key evidence includes encryption configuration files, key management procedures, access control lists for key stores, and decryption test reports. These show that encryption controls are both effective and maintained. Effective database encryption builds resilience. It ensures that even if an attacker gains access, the data remains unreadable and useless. Strong encryption is both a commitment to trust and a technical safeguard. #DatabaseSecurity #Encryption #CyberSecurityAudit #ITAudit #CyberVerge #CyberYard #DataProtection #RiskManagement #KeyManagement #DataGovernance #GRC #InformationSecurity

Most product founders (or aspiring founders) think cybersecurity is something that can be added on as we go. In 2024, 68 % of breaches involved a non‑malicious human element, like misconfigurations or coding oversights. Security isn’t a checkbox at launch; it’s a mindset woven into every sprint, every pull request, every architectural decision. Here’s a playbook we, at GrayCyan, have developed: 1️⃣. Threat Model Upfront Before you write a single line of code, map out your attack surface. What data are you storing? Who could target it, and how? A lightweight threat model (even a few whiteboard sketches) helps you prioritize controls around your riskiest assets. 2️⃣. Secure Design Patterns Adopt proven patterns—like input validation, output encoding, and the principle of least privilege—right in your prototypes. Whether it’s microservices or monolithic apps, enforcing separation of concerns and privilege boundaries early means fewer surprises down the road. 3️⃣. Shift‑Left Testing Integrate static analysis (SAST), dependency scanning, and secret‑detection tools into your CI/CD pipeline. Automate these checks so that every pull request tells you if you’ve introduced a risky dependency or an insecure configuration—before it ever reaches production. 4️⃣. Continuous Code Reviews Encourage a culture of peer review focused on security. Build short checklists (e.g., avoid hard‑coded credentials, enforce secure defaults) and run them in review sessions. Rotate reviewers so everyone gets exposure to security pitfalls across the codebase. 5️⃣. Dynamic & Pen‑Test Cycles Complement static checks with dynamic application security testing (DAST) and periodic penetration tests. Even a quarterly or biannual pen‑test will surface issues you can’t catch with automated scans—like business‑logic flaws or subtle authentication gaps. 6️⃣. Educate & Empower Your Team Run regular “lunch‑and‑learn” workshops on topics like OWASP Top 10, secure cloud configurations, or incident response drills. When developers think like attackers, they write more resilient code—and spot risks early. 7️⃣. Plan for the Inevitable No system is 100 % immune. Build an incident response plan, practice it with tabletop exercises, and establish clear escalation paths. That way, when something does go wrong, you move from panic to precision—minimizing impact and restoring trust. At GrayCyan, we partner with founders (and upcoming founders that have amazing product ideas) to embed these practices as we build apps. If you’re ready to turn security from an afterthought into your competitive advantage, let’s connect.

Recently, a data breach class action was brought against a social media company after its age-verification vendor had a data breach and purportedly lost driver's licenses and other sensitive information. See https://lnkd.in/eqFp_drf. In response to the incident, the media has been primarily focused on (a) improving third-party risk management (TPRM) and (b) the downside of requiring age verification. See e.g., https://lnkd.in/eigV926V. Organizations collecting sensitive data, however, should consider whether they need to store this data online at all. Instead, organizations can create a token to establish that the individual's age has been verified, and then remove the sensitive data from everyday systems and store it in a highly secure, offline environment. Here are some more detailed suggetions on how to make this work: 1. Classify and Scope Sensitive Data First Identify exactly what needs tokenization: PII, PHI, payment data, credentials, etc. Map where it resides, how it flows, and who accesses it. Use a data inventory matrix to guide tokenization boundaries. 2. Choose the Right Tokenization Model For example, vaulted tokenization stores original data securely in a token vault. Vaultless tokenization uses algorithms to generate tokens without storing originals. Vaulted is better for offline storage, as it allows secure retrieval if needed. 3. Use Format-Preserving Tokens Maintain original data formats (e.g., SSNs, credit card numbers) so systems don’t break. This can enable legacy applications to function without major refactoring. 4. Encrypt the Token Vault Apply strong encryption (AES-256 or better) to the vault storing original data. Use hardware security modules (HSMs) or secure key management services to protect keys. 5. Separate Tokenization and De-Tokenization Functions Isolate services that generate tokens from those that reverse them. Apply role-based access controls (RBAC) and audit logs to both. 6. Avoid Storing Tokens and Originals Together Never store tokens and their corresponding original values in the same system. This defeats the purpose of tokenization and increases breach risk. 7. Store Offline in Secure, Air-Gapped Systems Use encrypted, access-controlled offline storage (e.g., external drives, secure vaults). Ensure physical security and limit access to authorized personnel only. 8. Rotate Keys and Tokens Periodically Implement key rotation policies to reduce long-term exposure. Re-tokenize data if token formats or algorithms change. 9. Monitor and Audit Token Usage Track token generation, access, and de-tokenization events. Use centralized logging and alerting to detect anomalies. 10. Align with Compliance Frameworks Ensure tokenization practices meet standards like PCI DSS, HIPAA, GDPR, or FedRAMP. Document policies and procedures for audits and incident response. Stay safe out there!

Do you think Data Governance: All Show, No Impact? → Polished policies ✓ → Fancy dashboards ✓ → Impressive jargon ✓ But here's the reality check: Most data governance initiatives look great in boardroom presentations yet fail to move the needle where it matters. The numbers don't lie. Poor data quality bleeds organizations dry—$12.9 million annually according to Gartner. Yet those who get governance right see 30% higher ROI by 2026. What's the difference? ❌It's not about the theater of governance. ✅It's about data engineers who embed governance principles directly into solution architectures, making data quality and compliance invisible infrastructure rather than visible overhead. Here’s a 6-step roadmap to build a resilient, secure, and transparent data foundation: 1️⃣ 𝗘𝘀𝘁𝗮𝗯𝗹𝗶𝘀𝗵 𝗥𝗼𝗹𝗲𝘀 & 𝗣𝗼𝗹𝗶𝗰𝗶𝗲𝘀 Define clear ownership, stewardship, and documentation standards. This sets the tone for accountability and consistency across teams. 2️⃣ 𝗔𝗰𝗰𝗲𝘀𝘀 𝗖𝗼𝗻𝘁𝗿𝗼𝗹 & 𝗦𝗲𝗰𝘂𝗿𝗶𝘁𝘆 Implement role-based access, encryption, and audit trails. Stay compliant with GDPR/CCPA and protect sensitive data from misuse. 3️⃣ 𝗗𝗮𝘁𝗮 𝗜𝗻𝘃𝗲𝗻𝘁𝗼𝗿𝘆 & 𝗖𝗹𝗮𝘀𝘀𝗶𝗳𝗶𝗰𝗮𝘁𝗶𝗼𝗻 Catalog all data assets. Tag them by sensitivity, usage, and business domain. Visibility is the first step to control. 4️⃣ 𝗠𝗼𝗻𝗶𝘁𝗼𝗿𝗶𝗻𝗴 & 𝗗𝗮𝘁𝗮 𝗤𝘂𝗮𝗹𝗶𝘁𝘆 𝗙𝗿𝗮𝗺𝗲𝘄𝗼𝗿𝗸 Set up automated checks for freshness, completeness, and accuracy. Use tools like dbt tests, Great Expectations, and Monte Carlo to catch issues early. 5️⃣ 𝗟𝗶𝗻𝗲𝗮𝗴𝗲 & 𝗜𝗺𝗽𝗮𝗰𝘁 𝗔𝗻𝗮𝗹𝘆𝘀𝗶𝘀 Track data flow from source to dashboard. When something breaks, know what’s affected and who needs to be informed. 6️⃣ 𝗦𝗟𝗔 𝗠𝗮𝗻𝗮𝗴𝗲𝗺𝗲𝗻𝘁 & 𝗥𝗲𝗽𝗼𝗿𝘁𝗶𝗻𝗴 Define SLAs for critical pipelines. Build dashboards that report uptime, latency, and failure rates—because business cares about reliability, not tech jargon. With the rising AI innovations, it's important to emphasise the governance aspects data engineers need to implement for robust data management. Do not underestimate the power of Data Quality and Validation by adapting: ↳ Automated data quality checks ↳ Schema validation frameworks ↳ Data lineage tracking ↳ Data quality SLAs ↳ Monitoring & alerting setup While it's equally important to consider the following Data Security & Privacy aspects: ↳ Threat Modeling ↳ Encryption Strategies ↳ Access Control ↳ Privacy by Design ↳ Compliance Expertise Some incredible folks to follow in this area - Chad Sanderson George Firican 🎯 Mark Freeman II Piotr Czarnas Dylan Anderson Who else would you like to add? ▶️ Stay tuned with me (Pooja) for more on Data Engineering. ♻️ Reshare if this resonates with you!

Security can’t be an afterthought - it must be built into the fabric of a product at every stage: design, development, deployment, and operation. I came across an interesting read in The Information on the risks from enterprise AI adoption. How do we do this at Glean? Our platform combines native security features with open data governance - providing up-to-date insights on data activity, identity, and permissions, making external security tools even more effective. Some other key steps and considerations: • Adopt modern security principles: Embrace zero trust models, apply the principle of least privilege, and shift-left by integrating security early. • Access controls: Implement strict authentication and adjust permissions dynamically to ensure users see only what they’re authorized to access. • Logging and audit trails: Maintain detailed, application-specific logs for user activity and security events to ensure compliance and visibility. • Customizable controls: Provide admins with tools to exclude specific data, documents, or sources from exposure to AI systems and other services. Security shouldn’t be a patchwork of bolted-on solutions. It needs to be embedded into every layer of a product, ensuring organizations remain compliant, resilient, and equipped to navigate evolving threats and regulatory demands.

The Cybersecurity and Infrastructure Security Agency (CISA), together with other organizations, published "Principles for the Secure Integration of Artificial Intelligence in Operational Technology (OT)," providing a comprehensive framework for critical infrastructure operators evaluating or deploying AI within industrial environments. This guidance outlines four key principles to leverage the benefits of AI in OT systems while reducing risk: 1. Understand the unique risks and potential impacts of AI integration into OT environments, the importance of educating personnel on these risks, and the secure AI development lifecycle.  2. Assess the specific business case for AI use in OT environments and manage OT data security risks, the role of vendors, and the immediate and long-term challenges of AI integration 3. Implement robust governance mechanisms, integrate AI into existing security frameworks, continuously test and evaluate AI models, and consider regulatory compliance.  4. Implement oversight mechanisms to ensure the safe operation and cybersecurity of AI-enabled OT systems, maintain transparency, and integrate AI into incident response plans. The guidance recommends addressing AI-related risks in OT environments by: • Conducting a rigorous pre-deployment assessment. • Applying AI-aware threat modeling that includes adversarial attacks, model manipulation, data poisoning, and exploitation of AI-enabled features. • Strengthening data governance by protecting training and operational data, controlling access, validating data quality, and preventing exposure of sensitive engineering information. • Testing AI systems in non-production environments using hardware-in-the-loop setups, realistic scenarios, and safety-critical edge cases before deployment. • Implementing continuous monitoring of AI performance, outputs, anomalies, and model drift, with the ability to trace decisions and audit system behavior. • Maintaining human oversight through defined operator roles, escalation paths, and controls to verify AI outputs and override automated actions when needed. • Establishing safe-failure and fallback mechanisms that allow systems to revert to manual control or conventional automation during errors, abnormal behavior, or cyber incidents. • Integrating AI into existing cybersecurity and functional safety processes, ensuring alignment with risk assessments, change management, and incident response procedures. • Requiring vendor transparency on embedded AI components, data usage, model behavior, update cycles, cybersecurity protections, and conditions for disabling AI capabilities. • Implementing lifecycle management practices such as periodic risk reviews, model re-evaluation, patching, retraining, and re-testing as systems evolve or operating environments change.

✳ Integrating AI, Privacy, and Information Security Governance ✳ Your approach to implementation should: 1. Define Your Strategic Context Begin by mapping out the internal and external factors impacting AI ethics, security, and privacy. Identify key regulations, stakeholder concerns, and organizational risks (ISO42001, Clause 4; ISO27001, Clause 4; ISO27701, Clause 5.2.1). Your goal should be to create unified objectives that address AI’s ethical impacts while maintaining data protection and privacy. 2. Establish a Multi-Faceted Policy Structure Policies need to reflect ethical AI use, secure data handling, and privacy safeguards. Ensure that policies clarify responsibilities for AI ethics, data security, and privacy management (ISO42001, Clause 5.2; ISO27001, Clause 5.2; ISO27701, Clause 5.3.2). Your top management must lead this effort, setting a clear tone that prioritizes both compliance and integrity across all systems (ISO42001, Clause 5.1; ISO27001, Clause 5.1; ISO27701, Clause 5.3.1). 3. Create an Integrated Risk Assessment Process Risk assessments should cover AI-specific threats (e.g., bias), security vulnerabilities (e.g., breaches), and privacy risks (e.g., PII exposure) simultaneously (ISO42001, Clause 6.1.2; ISO27001, Clause 6.1; ISO27701, Clause 5.4.1.2). By addressing these risks together, you can ensure a more comprehensive risk management plan that aligns with organizational priorities. 4. Develop Unified Controls and Documentation Documentation and controls must cover AI lifecycle management, data security, and privacy protection. Procedures must address ethical concerns and compliance requirements (ISO42001, Clause 7.5; ISO27001, Clause 7.5; ISO27701, Clause 5.5.5). Ensure that controls overlap, such as limiting access to AI systems to authorized users only, ensuring both security and ethical transparency (ISO27001, Annex A.9; ISO42001, Clause 8.1; ISO27701, Clause 5.6.3). 5. Coordinate Integrated Audits and Reviews Plan audits that evaluate compliance with AI ethics, data protection, and privacy principles together (ISO42001, Clause 9.2; ISO27001, Clause 9.2; ISO27701, Clause 5.7.2). During management reviews, analyze the performance of all integrated systems and identify improvements (ISO42001, Clause 9.3; ISO27001, Clause 9.3; ISO27701, Clause 5.7.3). 6. Leverage Technology to Support Integration Use GRC tools to manage risks across AI, information security, and privacy. Integrate AI for anomaly detection, breach prevention, and privacy safeguards (ISO42001, Clause 8.1; ISO27001, Annex A.14; ISO27701, Clause 5.6). 7. Foster an Organizational Culture of Ethics, Security, and Privacy Training programs must address ethical AI use, secure data handling, and privacy rights simultaneously (ISO42001, Clause 7.3; ISO27001, Clause 7.2; ISO27701, Clause 5.5.3). Encourage a mindset where employees actively integrate ethics, security, and privacy into their roles (ISO27701, Clause 5.5.4).
