As businesses migrate to the cloud and adopt Internet of Things (IoT) devices, the attack surface has significantly expanded. Cloud computing offers scalability and flexibility, but it also introduces new risks. Misconfigured cloud storage, weak identity and access management (IAM), and insecure APIs are common vulnerabilities. Cloud providers use a shared responsibility model, where the provider secures the infrastructure, but customers must secure their data and configurations.
Key strategies for cloud security include enabling multi-factor authentication (MFA), applying the principle of least privilege, encrypting data at rest and in transit, and using continuous monitoring and auditing tools. Cloud-native security tools, such as AWS GuardDuty or Azure Security Center, help identify misconfigurations and potential threats in real-time.
IoT devices—ranging from smart home gadgets to industrial control systems—pose even more unique challenges. Many lack proper security controls, receive infrequent updates, or use hardcoded credentials, making them easy targets for attackers. Once compromised, these devices can be used in botnets or as entry points into larger networks.
To secure IoT environments, organizations should segment their networks, implement device authentication, and regularly update firmware. Adopting standards like the Zero Trust model is also effective. It assumes no device or user should be trusted by default, even if already inside the network perimeter.
In both cloud and IoT ecosystems, visibility and control are critical. Organizations must maintain a clear inventory of assets, monitor traffic for anomalies, and automate responses where possible to reduce the risk of breaches.
