As industrial systems become more connected, yesterday’s defenses no longer hold. ❌ Firewalls and VPNs can’t stop modern threats that move quickly and quietly. ❌ Shared credentials and third-party access leave critical operations exposed. ❌ Attackers don’t need to break in anymore, too often, they simply log in. Our new whitepaper explains why Zero-Trust Network Access (ZTNA) is becoming essential for protecting operational technology, and how it can: ✅Harden OT environments against evolving threats ✅Secure remote access without VPN sprawl ✅Provide visibility and control across vendors and distributed assets 👉 Download the full whitepaper from our website and see how Zero Trust can transform your OT security posture: https://lnkd.in/gpBZUNxZ  #OTSecurity #ZeroTrust #SmartBuildings #ICS #Cybersecurity #CriticalInfrastructure #NeeveNetwork

🚦 Why Firewalls Matter in Networking In today’s connected world, every packet entering or leaving a network carries potential risks. That’s where the firewall steps in—the first line of defense. Here’s why firewalls are indispensable: 🔒 Security – They block malicious traffic, intrusions, and unauthorized access. 🛡️ Access Control – Define who/what can enter your network while keeping threats out. 🌐 Segmentation – Isolate critical systems to limit damage if an attack occurs. 📊 Monitoring – Log and analyze traffic for early threat detection. ⚡ Performance – Prevent denial-of-service attacks and optimize bandwidth for critical apps. 🧩 Next-Gen Features – From application-aware filtering to intrusion prevention and VPN support. 🔗 In short: A firewall isn’t just a device—it’s your network’s security guard, ensuring safety, stability, and trust.

⚠️ A wake-up call for critical infrastructure security In April 2025, hackers didn’t need advanced malware or a zero-day exploit to compromise a Norwegian dam. They found an internet-facing device protected by only a weak password and that alone gave them the keys to remotely open a floodgate for over four hours, releasing 7 million liters of water downstream. Fortunately, no lives were lost and the infrastructure held. But this incident is more than a close call, it’s a clear signal of how geopolitical actors are shifting toward cyber sabotage as a tool of influence. Key takeaways: 🔵 Weakest link exploited – A single weak password on an internet-facing control system enabled attackers to manipulate dam operations. 🔵 Hybrid warfare in action – The attack wasn’t designed for destruction, but to sow fear and demonstrate capability. 🔵 Cyber hygiene saves lives – Strong authentication, strict segmentation and reduced remote exposure are no longer optional, they’re essential for resilience. At Obrix Security, we help industrial and critical-infrastructure operators close these exact gaps, building resilience against ransomware, hacktivist groups and state-linked actors before incidents like this escalate. 👉 Let’s talk if your operations depend on OT systems that cannot afford even a four-hour compromise. #Cybersecurity #OTSecurity #CriticalInfrastructure #OperationalTechnology #Resilience

The evolution of Endpoint Security is a story of adaptation, each stage building on the lessons of the one before it. In the late 1980s through the mid 2000s, antivirus defined the frontline of defense. It scanned files on each endpoint and matched hashes against a central database, blocking known viruses, worms and trojans. However, it had a critical weakness, anything new and unknown slipped through the cracks. By 2007, the Endpoint Protection Platform signaled a shift. It combined next generation antivirus with host firewall, intrusion prevention, application control and device use policies in a single agent. Layered prevention methods like vulnerability shielding and behavioral controls were added, making endpoints less dependent on signatures alone. From 2013 onward, Endpoint Detection and Response redefined the approach. Instead of focusing only on prevention, EDR continuously recorded process activity, network connections and system changes. Security teams gained the ability to hunt threats in real time and perform forensic investigation. Fileless attacks and stealthy intrusions could be detected, and defenders could pivot laterally to contain them. It was a shift from building walls, to shining lights inside the system. By 2018, Extended Detection and Response expanded the scope even further. XDR ingested and correlated telemetry not just from endpoints but also from networks, cloud, email and identity systems. It unified cross layer analytics and automated playbooks, giving security teams a centralized view to detect, prioritize and remediate threats across the entire infrastructure. This marked the transition from siloed defenses to integrated ecosystems, where insights from one layer could inform protection across many. Each stage represents a response to the growing sophistication of attackers. What began with scanning files for known signatures, has grown into a discipline that integrates signals from every layer of the enterprise. #Cybersecurity #EndpointSecurity #EDR #XDR #InfoSec #ThreatDetection #SecurityOperations #CyberResilience #NetworkSecurity #CloudSecurity

Ever wondered how data flows through a corporate fortress? Let's talk about mapping networks and the tools that make it possible. 🔍 Here’s a simplified, ethical process a security analyst might use to understand network accessibility, with proper authorization: 🌐 Discovery & Footprinting: Use passive recon tools like #Faddom to map the network topology without sending a single packet. 🔍 Firewall Analysis: A tool like #Nmap probes discovered IPs to see which gates (ports) are open, closed, or filtered. 📡 Traffic Inspection: #Wireshark analyzes live traffic (on your own network) to see what's inside the packets the firewall lets through. 🤖 Vulnerability Scanning: Scanners like #Nessus check exposed services for unpatched vulnerabilities or misconfigurations. � Proxy & VPN Testing: Tests the effectiveness of egress/ingress filtering and content policies. ⚠️ CRITICAL NOTE: This process is only legal and ethical with explicit, written permission. Unauthorized access is a crime. The goal isn't to '#manipulate' an #ISP—it's to think like an adversary to build stronger defenses. Continuous monitoring with tools like #Obkio is key to detecting these activities. #Cybersecurity #NetworkSecurity #Firewall #EthicalHacking #InfoSec #PenTesting #WAN #ITInfrastructure
