You're concerned about network security. How can you effectively manage risks with IoT devices?

Most of your IoT devices communicate over WiFi 2.4GHz. It's essential to use a tool that can discover and classify all your devices, including 'shadow devices' that might connect to your critical network and other devices. Ensure you map all your WiFi-Direct connections, as each one can create a potential vulnerability in your network and corporate-secured devices. Several solutions are available for this. After initial mapping and classification, use a tool that can block any unapproved connections or activities over the air.

Sin duda tener clara la superficie de riesgo mediante la identificación de activos, características, amenazas y vulnerabilidades de cada activo nos dará una visión de cómo enfocar mejor los esfuerzos de protección, no todo el entorno se protege por igual. Basemos la estrategia de protección en riesgos de ciberseguridad para el negocio.

To manage IoT risks, maintain an up-to-date device inventory and segment networks to isolate IoT devices. Use unique, strong credentials and enforce strict access controls. Regularly update device firmware and enable automated patches. Secure data with strong encryption and protect sensitive information. Implement continuous monitoring and centralized logging for anomaly detection. Use IDS/IPS and firewalls to safeguard communications. Develop policies for secure device management, choose secure vendors, and create IoT-specific incident response plans. Educate users on IoT risks and follow industry standards for compliance.

With the diverse and increasing number of devices connecting to networks, companies must implement a robust inventory and classification process. This is key to understanding device functionality, criticality, and the data they handle, enabling a thorough risk assessment of their vulnerabilities and threats. Based on this assessment, effective risk mitigation controls can be implemented. By systematically addressing these aspects, organizations can effectively assess and mitigate the risks associated with IoT devices, enhancing their overall security posture.

Network security is a big concern with IoT devices since they can be numerous and have varying levels of built-in security. Here are some steps you can take to manage risks with IoT devices: Strong Passwords. Updates. Secure Networks. Device Permissions. Network Segregation. Firewalls. Manufacturer Research.

El acceso seguro y remoto en los entornos operativos es una de las necesidades de negocio de las cuales no podemos prescindir, sin embargo como profesionales de ciberseguridad debemos habilitar las funciones de negocio de manera segura, garantizando no solo el acceso seguro sino también una rendición de cuentas, un monitoreo constante así como la gestión de dichas identidades

Network Segmenation is very important in a business environment as it provides unique security delivering more control over network traffic, optimising network performance. One example for network segmenation is having VLANs. Different departments can have diffferent vlans so they cant intervene with different departments in a network thus improve networks and security of a business

Network segmentation also provides a layer of security by isolating this IoT network from other IT infrastructure networks. Therefore will reduce impact of cyber attacks. Applying specific network filtering rules and policies will restrict access to IoT network and keep it more safe.

La segmentación y segregación de redes IOT o bien de rede OT de IT debería ser uno de los primeros pasos en la estrategia de protección de estos entornos, blindemos ambos entornos para minimizar el tama?o de la superficie de riesgo.

Keeping IoT gadgets up to date is important for network protection. Manufacturers launch firmware updates to deal with protection vulnerabilities, and making use of those updates directly is crucial to guard against potential assaults. Setting gadgets to update routinely or following a normal agenda for manual updates facilitates ensure that all gadgets are running the modern day, most stable software. This exercise minimizes the window of opportunity for attackers to make the most outdated structures, decreasing the hazard of breaches and maintaining the integrity of the community. Regularly checking for updates and applying them is a easy but powerful manner to protect IoT devices.

Keeping IoT devices updated is essential in maintaining network security. It’s very hard to make sure the systems is working properly unless you are checking and understanding the important updates necessary is applied.

Continuous monitoring of IoT devices using SIEM systems is crucial for real-time threat detection and response. By analyzing data patterns from IoT devices, SIEM systems can quickly identify potential cyber attacks, prompting immediate action. Establishing a 24/7 monitoring protocol is essential to swiftly detect and mitigate security incidents, maintaining the integrity and safety of your network environment.

Be cognizant of the risk of exfoliation. Every device has a specific domain it communicates with on a regular basis, some pull their updates from another domain. Log all flows at the router, after a period identify the legitimate servers and block access to any others. Assume your devices already are compromised or soon will be, but by blocking its access to the Command & Control server you will render the exploit useless to the attacker.

El monitoreo no sólo debe ser basado en los alertamientos de herramientas de manera pasiva, debemos robustecer el monitoreo con capacidades de analítica que provea capacidades de proactividad entorno a comportamientos maliciosos, técnicas y tácticas de ataque y con ello detectar amenazas en etapas iniciales de la ejecución de un vector de ataque

Just because something is connected online doesn't imply safety. Remember, prioritizing security is crucial. Let's strike a balance between convenience and safety. It only takes one opportunity for malicious actors. We must remain vigilant at all times. Stay proactive, anticipate, and prevent cyber threats. Treat your data as a postcard, not an envelope. Ensure its protection at all costs. Let's emphasize prevention over reaction.

El reto actual entorno a la capacitación, concientización y comunicación no solo involucra los mensajes técnicos de ciberseguridad, hoy hay que incluir también la generación de material con enfoques digitales atractivos de corta duración, haciendo un símil al manejo de redes sociales para tener un mejor impacto en la audiencia
