What do you do if your IoT devices are vulnerable to cyber attacks?

In case any of them will be under threat of an attack, update immediately all the firmware and software to its most recent version, as manufacturers will release patches for vulnerabilities. Replace default passwords for each device with strong, unique ones and update on a regular basis. Use an extremely strong Wi-Fi network that is heavily encrypted, and possibly use a separate network for IoT devices just to have them on another one than your critical devices. If not needed, turn off any other features and services that may be exploited. Look for any suspicious device activity that would signal a breach. Educate yourself on IoT security best practices, and consider a reputable security solution for IoT environments.

Consider using a product such as Microsoft Defender for IoT, which offers the following features: - Risk-based vulnerability management: With a risk-focused approach, you can enhance your security measures, reduce the attack surface, and eliminate vulnerabilities by identifying and visualizing the most probable paths of cyberattack. Cyberthreat detection using IoT and OT behavioral analytics: You can detect cyberattacks by employing machine learning, behavioral analytics, and IoT-aware and OT-aware cyberthreat intelligence. This feature uses full-fidelity packet captures to enhance the accuracy of cyber threat detection.

An important risk aspect to be considered related to IoT devices is also to determine if the software is updated remotely and, if the data traffic allows for techniques similar to packets injection or reverse engineering the protocol, especially in sensitive areas where vulnerabilities must not exist.

We use new and updated equipment in the network infrastructure. We always plan to hardening our network infrastructure and manage security patches.and planing for backup and use new equipment. Organized information and network security training courses for personnel.

There are scanners and tools which would be able to scan your network and find vulnerability and share you result. It is good idea to run scan and find vulnerable devices and also take all necessary steps to collect data about your environment.

Manter o firmware dos seus dispositivos IoT atualizado sempre será fundamental para garantir a segurança. Os fabricantes regularmente lançam atualizações para corrigir vulnerabilidades conhecidas. Verificar regularmente se há atualizações disponíveis e aplique-as assim que possível. Se possível, ative o recurso de atualização automática para garantir proteção contínua contra ameaças emergentes.

Updating the firmware is really important and critical. Out of date systems are good target for cybercriminals. Keep an eye on status of firmware and make sure regularly update them.

If your IoT devices are vulnerable to cyber attacks, changing passwords is crucial for several reasons: 1. Mitigating Risk: Default or weak passwords are common entry points for attackers. Changing them reduces the risk of unauthorized access. 2. Preventing Unauthorized Control: Compromised IoT devices can be controlled remotely. Changing passwords limits unauthorized control over your devices. 3. Protecting Personal Data: IoT devices often collect and transmit sensitive data. Strong passwords safeguard your privacy and prevent data breaches. 4. Staying Ahead of Threats: Regularly changing passwords helps stay ahead of potential attacks. Remember, proactive password management is essential for securing your IoT ecosystem.

As senhas padrões em dispositivos IoT são um ponto fraco conhecido. 1. Sempre altere as senhas padrão para opções fortes e exclusivas assim que configurar um novo dispositivo. 2. Utilize senhas complexas, combinando letras, números e símbolos, e evite reutilizá-las em diferentes dispositivos ou serviços. 3. Considere também o uso de um gerenciador de senhas para manter o controle e a segurança de suas credenciais.

A rede doméstica é a base do seu ecossistema IoT e deve ser protegida adequadamente. Recomendação: 1. Comece alterando o nome e a senha padrão da sua rede Wi-Fi para algo único e robusto. 2. Utilize a criptografia WPA3, se disponível, em seu roteador, pois oferece uma camada adicional de segurança em comparação com os protocolos mais antigos. 3. Além disso, considere segmentar sua rede, criando uma rede separada exclusivamente para seus dispositivos IoT. Isso isola esses dispositivos de seus principais dispositivos de computação, ajudando a limitar possíveis violações e fornecendo uma camada adicional de proteção à sua rede doméstica.

If possible put IoT devices inside an intranet where is not accessible to outside and only connect to internet when needed. It is also good idea to create isolated network for IoT devices, so even if device compromise, they won't be able to compromise your entire network.

To monitor activity regarding what to do if your IoT devices are vulnerable to cyber attacks, you should stay informed about security updates and patches from the manufacturer or trusted sources. Assess vulnerabilities using security tools, apply recommended security measures such as changing default passwords and enabling encryption, and ensure that devices have the latest firmware updates installed. Separate IoT devices from critical systems on your network, monitor network traffic for suspicious activity, and regularly back up data. Educate users about IoT security to recognize and respond to potential threats.
