Your IoT devices are potential targets for DDoS attacks. How can you mitigate the risk effectively?
IoT (Internet of Things) devices are increasingly becoming targets for Distributed Denial of Service (DDoS) attacks. These attacks can disrupt your network and compromise security. Here's how to safeguard your IoT devices effectively:

To mitigate DDoS risks for IoT devices, secure them with strong, unique credentials, regular firmware updates, and disable unused features. Isolate IoT networks, use firewalls, and monitor traffic for anomalies. Leverage DDoS protection services and threat intelligence to block malicious traffic. Plan and test an incident response strategy for effective recovery.

Categorings IoT uner two major bucket- Personal/ Home based IoT devices *Make sure the default passwords are changed (more prone to dictionary attack- once the creds are obtained; it's easy to carry out DoS or DDoS). *Securing network (firewall rules, using VPN, strong auth mechanism & implementing strong password). Industrial/ Commercial devices IoT devices *Disabling UPnP *Isolated VLAN in the internal network (can have dedicated security policy & firewall rules for Inbound traffic). Internal network should have IDS & IPS. *Strong auth (MFA)/ strong password policy *Have a program to refrain degrading security protocols (a bridge to work on secure protocols- TLS1.2, SSH, HTTPS etc.) *logging and assessing *Upgrade & patching

Other than these, we also look at few more controls: 1. Perimeter firewall blocks DDoS attacks - most next gen firewalls have these features. 2. Limit internet access to and from these IoT's, including at domain, URL, port/ service, etc. 3. Use proxy or DMZ network or NATing to protect/ hide the IoT IP's. 4. Keep scanning regularly for any vuln in the IoT's.

AI-based anomaly detection for live DDoS protection. Optimize firewall rules. Consider cloud-based anti-DDoS protection. Implement secure anti-DDoS routing. I some specific industrial IoT systems also Modbus and OCP (OT-security) can help in some situations.
-
Beyond basic security hygiene, a robust IoT defense demands a multi-layered strategy. We need real-time monitoring and anomaly detection to identify DDoS attacks targeting connected devices. Concurrently, enforce rate limiting and granular traffic filtering at the network perimeter to mitigate impact and contain malicious traffic. This proactive approach, combining preventative measures with continuous monitoring and dynamic response, is crucial to minimize risk to our operations from IoT-focused DDoS threats.
