Household technology from televisions to doorbell security systems make our lives easier but also provide opportunities for hackers to infiltrate your home network. In one week a home with smart devices could be exposed to more than 12,000 hacking or unknown scanning attacks1 from around the world.
Keeping your home secure from cyber risk is critical. Essentially any device that relies on an internet connection could be vulnerable. In some cases this is because the manufacturer has failed to put adequate cybersecurity safeguards in place due to cost or expediency considerations.
Another reason is the widespread availability of simple scanning tools with the ability to quickly provide intelligence about targeted devices or networks. Cyber criminals use these to observe and/or steal data.
A common entry point for hackers to gain access to devices and systems is via port scanning. A port is a point on a computer where information exchange takes place between programs, the internet and computers or devices.
Port scanning enables hackers to identify weaknesses or openings in a network that can be used to gain access by revealing:
Hackers can also use scanning to access the internet protocol (IP) addresses and hostnames of devices connected to the network. This helps them to:
Some commonly used smart devices have inherent weaknesses that can be exploited by hackers.
In a connected smart home environment if one device is compromised by hackers it can provide access to all your other devices — and data — on the same network.
If you work for a business that has adopted a work from home or hybrid model this can present a security issue for your employer. If one of your personal devices gets hacked and other devices connected to the same network are compromised that can include the company laptop if it doesn't have adequate security controls.
In 2020 the Federal Government released a voluntary Code of Practice as a step towards addressing the security of smart devices in Australia, containing 13 principles covering government expectations of the manufacturers of smart products.
The Australian Signals Directorate's Australian Cyber Security Centre (ACSC) also developed a complementary Internet of Things guide to help home users and small and medium businesses buy, use and dispose of smart devices securely.
More recently the Department of Home Affairs and the Australian Signals Directorate announced calls for submission for the development of a regulatory Code of Practice, resulting in a summary of the public consultation. Further action to secure smart devices remains under governmental consideration.
While regulatory measures under development will take time to directly benefit consumers there are key actions you can take to protect your home network and data security.
A takeaway is that every connected device can be used as a stepping stone to others in a cyber attack. While you can't prevent scanning by hackers, it is possible to minimise the attack opportunities and reduce your chances of being hacked by adopting a proactive approach to cybersecurity. This is just as important in the home as it is in the workplace — especially if the two cross over.
