Security & Data Hygiene for Automation Workflows: Practical Steps to Protect Users and Data Security best practices for automation workflows are critical for protecting user data, even in smaller-scale products and systems. While automation drives efficiency, it also introduces unique considerations for data hygiene and threat surfaces. Implementing robust security from the outset prevents costly breaches and builds user trust. Here are practical steps for engineers and architects designing automated processes: 1️⃣ Principle of Least Privilege: Grant automation accounts (service principals, API keys) only the permissions absolutely necessary for their tasks. Regularly review and revoke unnecessary access. Avoid using broad administrative privileges. 2️⃣ Input Validation and Sanitization: All data entering an automated workflow, whether from internal or external sources, must be rigorously validated and sanitized. This prevents injection attacks, data corruption, and ensures the workflow processes only expected, safe inputs. 3️⃣ Secure Credential Management: Never hardcode API keys, database credentials, or sensitive tokens directly into your automation scripts or configuration files. Utilize secure secrets management services (e.g., HashiCorp Vault, AWS Secrets Manager, Azure Key Vault) or environment variables during deployment. 4️⃣ Data Minimization & Encryption: Collect and process only the data essential for the workflow's function. Encrypt sensitive data both in transit (e.g., TLS) and at rest (e.g., encrypted databases, object storage). Implement data retention policies to delete data that is no longer needed. 5️⃣ Comprehensive Logging and Monitoring: Implement detailed logging for all automation activities, including successful operations, failures, and access attempts. Integrate these logs with centralized monitoring and alerting systems to quickly detect unusual behavior, unauthorized access, or potential security incidents. 6️⃣ Regular Security Audits: Periodically audit your automation workflows, their underlying infrastructure, and associated access policies. As systems evolve, so do potential vulnerabilities. Regular reviews help identify and remediate risks before they are exploited. By integrating these practices, engineers can build automation workflows that are not only efficient but also inherently secure and trustworthy. Protecting user data is a shared responsibility, and it starts with proactive design. #Automation #Security #DataPrivacy #DevSecOps #CloudSecurity #Engineering #DataProtection #ScalableArchitecture

Contextual Security, what is it? Often time, in the past, vendors have different lanes: Data Security, Identity Access Management, and Model Security. Each vendor has a strong suit in each of the lanes that they are playing. As GenAI evolves, however, it’s increasing harder to secure enterprise adoption of GenAI. Traditional vendors would have a hard time to protect against situation where: an IT director asks about financial statements next year via GenAI tools (Microsoft Copilot, OpenAI Enterprise, Google Gemini, Salesforce Agentforce, etc.) It’s difficult to detect because: 1. Data: it’s accessing sensitive data that users have permissions to 2. Identity: User is ligitimate, authorized user 3. Model: user is accessing a sanctioned GenAI application in the enterprise. Another scenario is when a doctor accessing PHI data. Because if you just look at Data Security lane, PHI is being accessed. If you just look at Model/Identity, the user is attempting to access sensitive data. So, without the other two contexts, there will be a lot of False Positives. This is where we as the industry needs to get to: Contextual Security (similar to how we have prompt engineering vs context engineering). The above threat vector can only be accurately detect if the three contexts come and work together. That’s what Contextual Security is. And Opsin is at the fore front of it! We incorporate all three in our stack to effectively protect Enterprise GenAI usage. What's your view on Contextual Security? P.S. Excuse me for my horrible Powerpoint drawing! Just want to illustrate my points. #ContextualSecurity #GenAI

Are you still setting up the total log retention in Microsoft Sentinel manually? Proud to share an automated solution I developed to streamline Microsoft Sentinel log retention management — a time-consuming task that often drains hours from Security Operations teams. Managing log retention across hundreds of Sentinel tables manually can be tedious, error-prone, and overwhelming. To solve this, I created a custom PowerShell script that automates the entire process, enabling bulk updates of total log retention settings in just a few minutes. The script includes: ✔️ Bulk update capability for all tables at once ✔️ Easy exclusion for specific tables as needed ✔️ Automated Azure authentication and token refresh ✔️ Clear feedback on update success or failures This tool saves valuable time, reduces human error, and empowers SOCs to focus on what really matters — proactive threat detection and response. Check out the detailed blog to learn more about the script and how to implement it effortlessly: 👉 https://lnkd.in/gnU9WRbw #MicrosoftSentinel #PowerShell #Automation #SecurityOperations #CloudSecurity #InspiraEnterprise #InspiraConnect #Microsoft #Sentinel

Security & Data Hygiene for Automation Workflows: Practical steps to protect users and data in small-scale products Protect your users and data! Learn practical security and data hygiene measures for your automation workflows. Even in small-scale products, unattended processes handle sensitive information. Overlooking security fundamentals from the start can expose you to significant risks, impacting trust, compliance, and your reputation. Implementing robust security doesn't require a large budget or complex tooling. Focus on these actionable steps to build more resilient automation: 1️⃣ Authentication & Authorization: Never hardcode credentials directly in code. Utilize secure environment variables, dedicated secret management services (e.g., AWS Secrets Manager, HashiCorp Vault), or OAuth flows. Ensure each service principal has unique, strong credentials and regularly rotates them. 2️⃣ Principle of Least Privilege: Grant automation accounts and services only the minimum necessary permissions to perform their specific tasks. This drastically limits the potential damage if a component is compromised, reducing the attack surface significantly. 3️⃣ Input Validation & Sanitization: Treat all external inputs as potentially hostile. Implement strict validation and sanitization on all data entering your workflows to prevent common vulnerabilities like SQL injection, cross-site scripting (XSS), or command injection. Never trust user input. 4️⃣ Secure Data Handling: Encrypt sensitive data both at rest (databases, file systems) and in transit (API calls, network communication) using industry-standard protocols. Define clear data retention policies and minimize the amount of sensitive data stored and processed. 5️⃣ Comprehensive Logging & Monitoring: Establish robust logging for all workflow activities, access attempts, and operational errors. Integrate with monitoring systems to detect anomalies or suspicious behavior promptly, enabling swift incident response and post-incident analysis. Proactive security integration into your development lifecycle, even for seemingly minor automations, is a critical investment. It builds resilience and protects your users, your data, and your reputation. #Automation #Security #DataHygiene #DevSecOps #SmallBusinessTech #WorkflowAutomation #CyberSecurity #TechTips
