From the horse’s mouth

A common issue that is being continually raised through the IT security circles is the lack of security associated with network-infrastructure devices and dedicated-function devices. This is more so with devices that are targeted at households or small businesses.
Typical issues include use of simple default user credentials which are rarely changed by the end-user once the device is commissioned and the ability to slip malware on to this class of device. This led to situations like the Mirai botnet used for distributed denial-of-service attacks along with a recent Russia-sponsored malware attack involving home-network routers.
Various government bodies aren’t letting industry handle this issue themselves and are using secondary legislation or mandated standards to enforce the availability of devices that are “secure by design”. This is in addition to technology standards bodies like Z-Wave who stand behind logo-driven standards using their clout to enforce a secure-by-design approach.
The German federal government took a step towards having home-network routers “secure by design”. This is by having the BSI who are the country’s federal office for information security determine the TR-03148 secure-design standard for this class of device. This addresses minimum standards for Wi-Fi network segments, the device management account and user experience, along with software quality control for the device’s firmware.
Similarly, the European Union have started on the legal framework for a “secure-by-design” certification approach, perhaps with what the press describe as an analogy to the “traffic-light” labelling on food and drink packaging to indicate nutritional value. It is based on their GDPR data-security and user-privacy efforts and both the German and European efforts are underscoring the European concern about data security and user privacy thanks to the existence of police states within Europe through the 20th century.
But the UK government have taken their own steps towards mandating home-network devices be designed for security. It will use their consumer-protection and trading-standards laws to have a security-rating label on these devices, with a long-term view of making these labels mandatory. It is in a similar vein to various product-labelling requirements for other consumer goods to denote factors like energy or water consumption or functionality abilities.
Here, the device will be have requirements like proper credential management for user and management credentials; proper software quality and integrity control including update and end-of-support policies; simplified setup and maintenance procedures; and the ability to remove personal data from the device or reset it to a known state such as when the customer relinquishes the device.
Other countries may use their trading-standards laws in this same vein to enforce a secure-by-design approach for dedicated-function devices sold to consumers and small businesses. It may also be part of various data-security and user-privacy remits that various jurisdictions will be pursuing.
The emphasis on having proper software quality and integrity requirements as part of a secure-by-design approach for modem routers, smart TVs and “smart-home” devices is something I value. This is due to the fact that a bug in the device’s firmware could make it vulnerable to a security exploit. As well, it will also encourage the ability to have these devices work with highly-optimised firmware and implement newer requirements effectively.
At least more countries are taking a step towards proper cybersecurity requirements for devices sold to households and small businesses by using labels and trading-standards requirements for this purpose.
