Most IT devices have some form of remote access, whether via web browser or app. As long as devices are accessed by an authorized user from within an internal network, this isn’t a problem. Unfortunately, many devices, especially routers and smart home gateways are also accessible from the internet. And that’s where the problems begin. In fact, they have never stopped. Open remote access is among the greatest yet unfortunately inevitable threats of IT devices. Anybody who can access the management interface can control the device and usually the owner will not notice. Devices that are connected to the internet are constantly scanned and scrutinized for vulnerabilities. Open remote management interfaces should be treated as the digital equivalent of a loaded gun. It can be used but you need to know exactly what you are doing and take every possible precaution.
Energy plants and factories have always been prime targets for delivering a devastating setback and psychological blow against an enemy. Today, successful attacks against critical infrastructure can be launched in cyberspace. In 2015, a cyber-attack on a Ukrainian power station caused a loss of power affecting 225,000 customers and the world took note. In the U.S., the Department of Homeland Security (DHS) has raised concerns over the growing number of cyber attacks on industrial control networks. In response, they recently published guidelines to “provide a strategic focus on security and enhance the trust framework that underpins the IoT ecosystem.” The document calls for a combined approach. Among the measures discussed are considered connectivity and defense in depth. Managed Virtual Private Network (VPN) connections and two-factor authentication can help secure critical connections to give IIoT data traffic the in-depth protection it needs.
The research and analyst firm techconsult issued a summary of the five major security vulnerabilities in SMEs and public organizations in Germany at the start of 2017. Their annual study Security-Bilanz Deutschland reviews IT and information security based on a representative survey of more than 500 interviews in companies and non-profit organizations. The results are sadly not that surprising each year. Although the organizations surveyed are aware of the problems and have the resources to deal with them, unfortunately they either approach issues through the wrong channels, inconsistently or too late.
The threat of cybercrime against retailers is ever present. According to the 2016 Global Threat Intelligence Report, retailers are the top targets and receive up to three times the number of attacks as second placed financial institutions. Around 70% of retailers in Europe admit to being targeted while 45% of the attacks are known to have been successful. In the past 12 months, the US retail sector has also seen repeated attacks on electronic point-of-sale (POS) systems as well as consistently high volumes of phishing emails aimed at tricking insiders into giving access to corporate networks. With online takings expected to account for 21% of overall sales in 2017, cybercriminals will continue to try and profit from any vulnerabilities they can find in retail systems. To counter this, retailers have a variety of mitigation techniques available to them including VPNs. The best security remains multi-layered since no single technology can nullify all threats at all times.
