Large organizations today are experiencing a rapid evolution in technology that is challenging traditional security systems and infrastructures. Corporate networks that once only had to support the connectivity of desk-bound workstations and a small number of laptops must now cope with thousands of laptops, tablets and phones along with a rapidly growing population of IIoT/M2M devices. VPNs are an integral part of any mobile device and IIoT security strategy. To manage all of these VPNs easily and efficiently without compromising end-user security requires the IT department to embrace a variety of strategies.
The RSA Conference (RSAC) is always a major highlight in the IT security professional calendar and this year’s show was no exception. In this blog, NCP engineering reviews some of the standout enterprise machine-to-machine (M2M), mobile client and cloud security trends to emerge from RSAC 2017. The show is also a win-win for NCP. Our strong track record with US technology partners means that NCP is well-known to US-base customers and prospects. At the same time, our experience in fulfilling Industrial Internet of Things (IIoT) or Industry 4.0 projects in Germany means we had a great deal of knowledge and insight to share with prospects in this security segment, one that is in its early stages in the United States.
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.
Internet of things products are small, networked and unfortunately have almost always little or no security. Sometimes this is down to a lack of willingness by the manufacturer but it is also partly due to the nature of the product – small and light also means that these devices have few resources for complex security features such as encryption and packet inspection. This leads to vulnerabilities, numerous attack vectors and ultimately to a bot device which can be abused by almost anyone. Following the latest large-scale attacks that primarily use IoT devices as a digital army there is a loud demand from those who want more legislation and governments to get involved. In a hearing before the Committee on Energy and Commerce of the US House of Representatives, the security guru Bruce Schneier stated that “catastrophic risks” would arise through the proliferation of insecure technology on the Internet.
In 2017, 69% of all applications will reside in the cloud according to Cisco. As we rely increasingly on benefits made possible by further advances in Industrial Internet of Things (IIoT) and mobile devices, it’s a statistic that will continue to rise. The challenge for enterprises today is how to protect data as it streams constantly between physical mobile/IIoT devices to virtual repositories in the cloud and back again. Until corporate IT departments fully manage and stay on top of security, large breaches will continue to make the headlines. Statistics revealed in the Ponemon Institute 2016 Global Cloud Data Security Study show there is still much to do. The study found that nearly half (49%) of cloud services in the enterprise are outside corporate IT’s domain, while around 47% of corporate data stored in cloud environments are not managed by the IT department.
