[EN] Day 43 of #100DaysOfOTCybersecurity What are some #OTCybersecurity solutions to follow the Defense-in-Depth model? 🛡🏭🛡 🤖 Virtual Patching: It's not always feasible or recommended to update security patches provided by vendors, especially for obsolete equipment where vendors no longer offer these patches leaving the equipment exposed. In those cases, virtual patching can be performed on critical process equipment using IPS technologies. 🌐 OT Network Segmentation: Network segmentation provides greater control and visibility of communications between zones and inter-zones compared to a flat network. Additionally, segmentation aligns with ISA/IEC #62443 standards. 🛂 OT Firewalls: These act as security guards controlling access to network ports, making it possible to properly restrict incoming and outgoing traffic. 👁 OT Industrial Detection Systems #IDS: Monitoring the OT network helps maintain visibility of asset inventory, vulnerabilities, and timely detection of threats. 🖥 OT Anti-malware Protection: #Legacy assets or critical systems require specialized OT anti-malware solutions to contain threats and ensure equipment availability. 📡 Secure Remote Access: A solution that allows you to visualize remote connections to equipment, observe sessions, and perform audits provides security for maintenance or configuration changes in production. With these types of solutions, the level of #cybersecurity maturity is increased 📈, and you can keep protected the industrial control systems #ICS. ⚙ ✅ Here's the second part of the #CISA certificate: "Mapping IT Defense-in-Depth Security Solutions to ICS - Part II" #100DiasDeCiberseguridadOT #100JoursDeCybersécuritéOT

🔐 Integrated OT Security Challenges and Recommendations In today's interconnected industrial landscape, Operational Technology (OT) systems face unique security challenges that demand robust strategies for protection and resilience. Here’s a breakdown of key challenges and corresponding recommendations: 1️⃣ Real-World Impact: OT disruptions can lead to significant economic and operational consequences. 2️⃣ Endpoint Vulnerabilities: OT devices often lack inherent security measures, making them vulnerable to cyber threats. 3️⃣ Patch Management: Effective management is crucial as OT systems cannot be patched on-the-fly. 4️⃣ System Connections: Increased connectivity introduces vulnerabilities, necessitating stringent access controls. 5️⃣ Regulations: Compliance with sector-specific security regulations is essential for operational continuity and legal adherence. 6️⃣ Monitoring & Incident Response: Real-time monitoring and a structured response plan are vital for early threat detection and mitigation. Implementing these recommendations ensures a proactive approach to safeguarding critical OT infrastructure against evolving cyber threats. Stay informed, stay secure. #OTSecurity #Cybersecurity #IndustrialSecurity #RiskManagement #Compliance #LinkedInSecurity

As per CISA recent report, Volt Typhoon actors are pre-positioning themselves on IT networks to enable lateral movement to OT assets to disrupt functions As per recent SANS report IT is the largest attach entry point to OT . What can you do? 1. 𝗣𝗿𝗼𝘁𝗲𝗰𝘁𝗶𝗼𝗻     ▪️Establish Control DMZ ▪️all inbound and outbound traffic to and from OT must stop at DMZ ▪️every traffic is inspected twice ▪️use segmentation inside the DMZ ▪️If possible,  use two pairs of firewalls north firewall under IT, south firewall under OT control. ▪️ISA/62443 Island mode control ▪️Separate IT  operations form OT operations especially AD, SIEM ,Patch Management 2. 𝗠𝗼𝗻𝗶𝘁𝗼𝗿𝗶𝗻𝗴     ▪️Deploy NIDS at choke points ▪️monitor boundary firewall log ▪️deploy Honeypots 3. 𝗢𝘁𝗵𝗲𝗿 𝘁𝗵𝗶𝗻𝗴𝘀 𝘁𝗼 𝗸𝗲𝗲𝗽 𝗶𝗻 𝗺𝗶𝗻𝗱: ▪️no sliver bullet ▪️the control is as strong as its user and configuration ▪️beware of dual homed devices ▪️periodic audit and tuning ▪️be ware of transient asset ▪️Take care of usb devices ▪️Keep your incident response plan near and ready what else? you tell me! #icscybersecurity #otcybersecurity #cybersecuritybitsandbytes

🛡Are your current security measures as effective as a National Managed Security Operation Center? In 2024, you should try these: 👉Implement Advanced Threat Detection: ✔Utilize state-of-the-art threat detection tools like Intrusion Detection Systems (IDS) and Security Information and Event Management (SIEM) software.  ✔These tools help monitor, detect, and respond to suspicious activities in real-time. Regularly update and configure these systems to recognize new threats. Conduct frequent training for your IT team on how to interpret alerts and take swift action. 👉Adopt Continuous Monitoring and Incident Response: ✔Establish a 24/7 monitoring system for your network infrastructure. Use automated scripts and AI-driven tools to identify and alert on anomalies.  ✔Develop a detailed incident response plan outlining steps for identifying, containing, eradicating, and recovering from security incidents. Conduct regular drills to ensure your team is prepared to respond efficiently. 👉Enhance Endpoint Security: ✔Deploy comprehensive endpoint protection software on all devices within your network. Ensure that antivirus, anti-malware, and firewall protections are active and updated.  ✔Implement strict access controls and enforce multi-factor authentication (MFA) to safeguard sensitive data. Regularly audit your endpoints for vulnerabilities and ensure all software patches are applied promptly. #CyberSecurity #ThreatDetection #ContinuousMonitoring #DataProtection #IncidentResponse #EndpointSecurity #ITSecurity #NetworkSecurity #MFA #SecurityAwareness Michael Johnson

Challenges With Vulnerability Management On Network devices ❌ If your edge devices are to be compromised there is a lot at stake, making it easy for threat actors to further gain control. ⭕Performing an authenticated scan on your network devices is a challenge in itself , most of the scanner agents are not supported. We need to have an account enabled for the scanner appliance to do an authentic scan. How do we handle this & provide maximum possible protection to legacy network devices? One way to overcome this is knowing what's there in your infrastructure, which again is the basics of vulnerability management. ✅How many devices are present? ✅How many are running with outdated OS ? Try to remove legacy devices as much as possible, sometimes it boils down to budget! ✅Have we implemented stringent hardening guidelines? ✅Follow the vendor for threats , news & patch releases. ✅Implementing well known solutions CISA KEV , EPSS & SSVC comes in handy where we can prioritise our vulnerabilities/asset & give attention to the most vulnerable asset. ✅Make sure the devices are logged properly in your SIEM, alerts are triggered/tracked properly for those devices. Give priority to those alerts triggered from these devices. #vulnerabilitymanagement #networksecurity #EdgeDevices #ContinuousVulnerabilityMansgrment
