Dongle Danger: Don’t let your company get caught out

They are a pain for users, but a necessity for software publishers

Hardware dongles are still in use as a means for software publishers to protect revenues. The publishers build software and expect to get paid for it when used.

While this is a good solution for publishers, users would like access software without the inconvenience of plugging in a dongle every time they want to use a protected application.

Over the years, activation codes have become a very popular way for software publishers to protect their intellectual property (the whole PC becomes, in effect, a dongle), but a lot of other vendors still use dongles to prevent profit erosion.

The problem with dongles are manifold. Users don't like them, can often lose them, and the dongles aren't as portable as you think they are (despite being small enough to pop in a pocket or purse).

The transition to USB from parallel ports

When dongles first came along, they used the old parallel port technology, which meant that multiple dongles could be "daisy-chained" one after the other, and still allow a peripheral, such as a printer or scanner, to also be connected. However, nowadays, most computers no longer sport a parallel port, having been superseded by USB technology.

This brings an added problem. USB dongles don't generally allow for this daisy-chaining and if you have multiple dongles, pretty soon you could run out of ports.

Another issue in years to come is when laptops stop using full-sized USB ports in favour of USB-C ports. If a software published provides a full-sized USB dongle and the user has no means of plugging in that dongle, how will they use the software they have legally purchased.

Dongles and the flexible/agile working issue

Dongles can also present issues when flexible and agile working are added to the corporate mix. With more people either working from home, working away from the office at clients, coffee shops, etc., or working in an office where employees no longer have a set place to work (I.e hotdesking), having to carry a dongle to access software becomes problematic.

An employee may not be at a computer where the protected software is installed. They maybe using the software via a remote terminal software and can't simply place the dongle in an available port. If they are working from a tablet, they may not have the right port to insert a dongle.

If two or more people share an application, then sharing the dongle is a problem if it must be physically transferred from one employee to another.

Another issue is when a remote worker has both a desktop computer at the office but also a laptop for working at home. It is all too easy for a user to forget to pack the dongle they were using to take to use on the other computer.

Using a dongle server can overcome such issues as these devices are stored safely on a corporate network and thus never go missing.

Infecting a network can be as easy as plugging a flash drive into a USB port, which is why many organisations have security policies that prevent users from using these USB ports as a precaution. This also means that USB-based software licence dongles will also be prevented from being used.  

Virtual environments

Thin clients and virtual environments are great for improving the security of organisations that use them. This is because they lock down the environment, protecting users and the organisations that deploy them. The drawback here is that thin clients often don't have enough USB ports if any. An issue if you want to use software that won't function without a dongle. A dongle server could be used here so that users have a central location for dongles that is easily accessible regardless of location or client.

Another issue with virtualisation and cloud is that virtual servers don't always reside on the same physical server. Any application requiring a software licence dongle to be plugged into a physical port may not be running on that physical server as the virtual server it is running on could be on the move between any number of physical servers. To overcome this issue, the virtual server needs to be aware of where a dongle is located on the network and attach to it accordingly.

Breakages, thefts, and loses

While electronic components do occasionally fail, dongle breakages are most likely to occur because of physical damage. One of the most common causes of damage is where a dongle is plugged into a rear-panel computer port and then gets crushed against a wall. A short extender can overcome such problem but having a dongle out in the open can still present other issues.

Organisations can suffer from casual theft of dongles because they look like USB memory sticks. Then the thief will most likely throw the dongle away when they realise that it is not a flash drive.

Dongles, like any USB stick can be lost by a user. Having this replaced can take days as the software company has to send a replacement dongle. For the software vendor, this means cancelling licences associated with a lost dongle and setting up new licences for the replacement.  

Using a dongle server

USB dongles can be made available over a network using a dongle server. Copy-protected software can be used as per normal but without the need to directly connect the licence dongle to a USB port of a computer.

A dongle in a dongle server works in the same way as one directly connected to a client, but over a point-to-point network connection. The licensing terms of the relevant software vendors are not circumvented at any time.

Ultimately, with the right tools and technologies, IT managers can meet both the expectations of users and the needs to simplify management and boost security.
