You who work or want to work in SOC need to understand a simple thing that changes everything: the game has changed. We no longer run after a missed alert — we anticipate. Look at this image here. It is the basics of a SOC that thinks, not just reacts. Check out the flow: Threat Intelligence (TI): This is where everything that helps you understand what's going on out there comes in — IOC feeds, dark web, OSINT, intelligence threat platforms... It's like looking at the weather forecast before leaving home. SIEM: The brain of the operation. Gathers logs from the cloud, endpoints, network... normalizes, correlates, analyzes. But alone, he is just a puzzle assembler. SOC. This is where the magic happens: - Threat Detection, - Incident Response, - Threat Hunting, - Security Monitoring (full-time monitoring). All this, orchestrated with intelligence. And here comes the key point: alert without context is noise. Alert with intelligence is decision. Do you want to evolve in SOC? It starts by understanding this flow. He learns to work with intelligence from the beginning. Because at the end of the day, what protects the business is not only technology... It's the strategy behind it. Thank you Denny Roger for nice sharing. #cybersecurity #soc #Threatintelligence

🔎 The ITSM Lens The People Side of ITSM – Building a Service-Oriented Culture A few years back, during a major incident in one of the banks I supported, every technical team rushed into action; logs were analyzed, patches were proposed, systems were rebooted. But amidst all the technical noise, one thing was missing: no one was talking to the end users. Then a branch manager called with a voice full of concern: “Do you know how this downtime is affecting the customers standing in front of me right now?” That question changed my entire perspective. 💡 IT Service Management is not just about processes, SLAs, or tools; it’s about people. Behind every ticket is a person relying on technology to get their work done. Building a service-oriented culture means remembering that technology exists to serve people, not the other way around. How do we build this culture? ✨ Empathy first – see beyond incidents and understand the human impact. 🤝 Collaboration – break silos and encourage teamwork. 📢 Clear communication – silence creates frustration, but updates build trust. 📚 Continuous learning – treat every incident as a chance to improve. At its core, ITSM thrives not because of the framework we adopt, but because of the mindset we cultivate. A true service-oriented culture transforms IT from being “the fixers” into trusted partners driving business success. 👉 How is your team putting people at the center of ITSM?

Role vs. Entitlement in SailPoint What is a Role? A role is a collection of permissions grouped together to simplify access management. Types of Roles in SailPoint 1. Business Roles – Aligned with job functions (e.g., “HR Manager,” “Finance Analyst”). 2. IT Roles – Technical roles granting access to systems and applications (e.g., “Database Administrator,” “Network Engineer”). 3. Application Roles – Specific to individual applications (e.g., “Salesforce Admin,” “SAP Finance User”). What is an Entitlement? An entitlement is a specific permission assigned within an application, such as: • “Read-only access to payroll reports” • “Modify customer records in Salesforce” • “Admin rights to AWS cloud resources” How Roles and Entitlements Work Together in SailPoint 1. A user is assigned a role (e.g., “Finance Manager”). 2. The role contains multiple entitlements (e.g., “View Financial Reports,” “Edit Budget Plans”). 3. If the user moves to a new role, entitlements change automatically. Best Practices for Managing Roles and Entitlements • Use Role-Based Access Control (RBAC) to reduce complexity. • Limit direct entitlement assignments – roles should be used to grant access instead. • Conduct periodic access reviews to validate entitlements and remove excessive permissions. By implementing structured role and entitlement management, organizations improve security, reduce role sprawl, and simplify identity governance. #IAM #SailPoint
