A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predefined security rules. It helps protect IoT devices from unauthorized access and malicious attacks.

An Intrusion Detection System (IDS) monitors network traffic and system activities to identify and alert on suspicious or malicious behavior. It helps security teams detect and respond to potential threats in real-time.

Regular firmware updates address known vulnerabilities and security patches. Keeping IoT devices up-to-date with the latest firmware versions helps mitigate potential security risks.

Multi-Factor Authentication (MFA) adds an extra layer of security by requiring multiple forms of identification, such as a password and a one-time code, to access IoT devices. This makes it more difficult for unauthorized individuals to gain access.

Transport Layer Security (TLS) is a widely used security protocol that provides encryption and authentication for data transmitted over the internet. It helps protect IoT devices from eavesdropping and man-in-the-middle attacks.

Access control lists (ACLs) are used to define and enforce access permissions for users or devices to specific resources or services within an IoT network. This helps prevent unauthorized access and maintain the confidentiality and integrity of sensitive data.

Securing physical access to IoT devices involves implementing measures to prevent unauthorized individuals from physically accessing and manipulating the devices. This can include using tamper-proof enclosures, implementing access control systems, and monitoring physical access points.

A Virtual Private Network (VPN) creates a secure tunnel over a public network, allowing IoT devices to securely communicate with each other or with a central server. This helps protect data transmissions from eavesdropping and unauthorized access.

Rate Limiting is a security mechanism used to control the rate at which requests are processed by an IoT device or service. It helps mitigate denial-of-service (DoS) attacks by limiting the number of requests that can be made within a specific time frame.

A security information and event management (SIEM) system collects, analyzes, and correlates security events from various sources within an IoT network. It helps security teams detect and respond to security incidents in a timely and effective manner.
