Connected Devices and Network Security

Connectivity is a fundamental requirement in the modern way of living. Establishing a balance between sharing information online and maintaining certain levels of privacy is essential for digital users. Internet of Things is paving the path for increased digitilisation.

Household essentials are developed with Internet connectivity
functionalities. Frequent use items such as toasters, fridges and televisions have smart capabilities.

While these items are contributing towards general convenience within a househould, replacing an array of manual tasks with smart functions. At the same time, IoT devices are introducing a myriad of privacy problems by collecting consumer data.

Mass collection of data exhibits a threat to the online security of a consumer. Adversaries may attempt to access consumer data by gaining a backdoor access to a network with mal-intent pre-planned to steal bank accounts or credit card data.

Protecting the home network

Robust home security mechanisms are necessary to thwart hackers. Lack of network security provides an easy route for cybercriminals to exploit vulnerabilities in IoT devices.

Strengthen home security by the following steps:

1. Change default passwords on all IoT Devices.

Default manufacturer passwords should be replaced with a secure password.

2. Enhance network security by implementing a separate network for IoT devices.

Connect IoT devices to a separate network from regular use systems such as computers, laptops and printers. This establishes a safe mode for essential use devices if IoT devices are infected.

3. Use encryption.

Where possible opt to use encryption on devices. Encrypted devices paired with strong unique passwords are a safety net for protecting personal information.

4. Set up strong firewalls.

Although firewalls cannot protect against all attacks, a good security measure is to implement the use of firewalls.
