Connectivity is on the rise by all accounts. Interoperability is where it's act. Languages, protocols, operating systems, identities, on-line profiles, devices, smart-phones, tablets, you name it, if connectivity isn't a feature it's not getting a look in.
If you look at pre-internet times (yes hard I know) device and data interconnectivity was seen as an important use case, but only implementable if deemed absolutely necessary. As tooling and applications now allow data passage with a few clicks, the network of connected devices becomes enormous.
Whilst this brings many end user benefits it can also bring with it management issues, data loss prevention concerns and data proliferation where perhaps it shouldn't.
Increased Connectivity is Great Right?
The main area of increase recently has been the rise of the smart-phone. Devices that now contain powerful processors, large portable micro-card storage and run operating systems with the same level of complexity of a desktop machine. Smart-phones can hop onto a wi-fi network in seconds and communicate over TCP/IP like any other device. Coupled with smart-phone 'always-on' capability, comes increased on-line connectivity. By this I'm referring to the services that the internet provides. For example, a Google account can link your phone contacts to your calendar, to your social network and in turn you can import your RSS feeds directly into a blog page and see the book recommendations from your friend feeds. A document on your laptop can easily be shared, stored and copied to your phone, tablet and work colleague seamlessly.
Why is it a Problem?
The biggest danger with inter-connectedness comes data management. If you use a basic cloud synchronisation service, you could quite easily have 3-4 copies of the same document. A local copy, an on-line archive, a collaborative copy and so on. Where is the ownership, protection and management of the original data? No longer is corporate data restricted to the private LAN. The boundaries of such a network are now blurred. If corporate data can be downloaded, viewed and edited on a tablet or smartphone using 3G where does the corporate security policy end? Data Loss Prevention can provide many answers. Endpoint device management is a major concern as is the security of Data-in-Motion. New technologies that focus on Information Rights Management that help restrict proliferated data access by unknown users is now popular. Data-at-Rest is quite a well known concern area and disk encryption for laptops is popular and remote-wipe is also a common feature for smart-phones and tablets.
BYOD or Bring Your Own Device brings with it another complex set of security concerns. Should organisations realise the potential of individually owned devices to create an inter-connected grid of data exchange? What about employees with jail-broken phones, or phones with inconsistency patching, applications and so on. What happens with an employee leaves an organisation? Who owns the data and can it be legally wiped?
The expansion of the connectivity can create a blurring between the private and public networks and in turn cause policy jurisdiction issues. A concern in recent years has been the increase in the number of SCADA (Supervisory Control & Data Acquisition) system attacks. Historically these systems would be not have been so heavily inter-connected with the corporate network and in turn access to the internet. SCADA networks were generally separate from existing LAN infrastructures, using faster lower level protocols. As inter-connectivity with standard TCP/IP infrastructure increased, SCADA systems became inadvertently accessible via the internet and in turn more open to cyber and malicious software attacks.
It will be interesting to see as connectivity continues to increase at both the corporate, personal and industrial level, whether security policy and controls management can keep a pace, providing governance and support to help reduce data loss, attack and malicious software proliferation.
