Many cybersecurity events and breaches are the result of us failing to keep our computers and computer programs up to date. The process of keeping our systems up to date is known as PATCHING.
What is PATCHING?
Patching is regularly updating your systems by applying security updates provided by the software or device manufacturer.
Let’s look at this for a second, software or device manufacturer. That means that both our software and our hardware need to be patched or kept up to date.
Patching Hardware: Devices such as routers, switches, printers, and other items have built in software known as firmware. The first step in keeping your devices up to date is to register each of your devices with the device manufacturer. Once you have registered the device, the manufacturer will send you email notices when they have a software update for the device. The email will contain instructions on how to update the device. Many of these updates are security updates and are vital to keeping your network and systems protected from hackers.
Sine devices are ‘smart’. They check back with the manufacturer and ask “Is there an update available for me?” If there is an update, the device may tell you that an update is available and have you push a button to update the device. Your cell phone is a great example of a device checking for updates and then prompting you to do the update.
Patching Software: The process here is very similar to patching hardware. The first step is to register the software with the manufacturer. Current software systems are often set to check with the manufacturer and ask if an update is available the software will prompt you to do an upgrade. Each and every program on your computer needs to be kept up to date, even if you do not use the program very often. It is also important to keep an inventory of all of the software and hardware that you have and a list of when you last checked for updates. The department of Health and Human Services recommends that all software used in healthcare be patched at least monthly if not more often.
There are times when a manufacturer stops supporting a device or a piece of software. This is known as the “End of Life” for that device or program. Once something has reached the “End of Life” the manufacturer will no longer distribute updates to keep the product secure. It is very important that you replace any devices that have reached their end of life and remove any software products that have reached their End of Life as these items represent a huge security risk for your practice.
One of the biggest software items that we need to keep up to date is the Operating System of our computers. You should have your system set to automatically update the operating system at least once a month and you should register your operating system so that you will receive email notifications should there be any urgent updates you need to manually apply.
Many of the large data breaches that have hit the news over the last few years are the result of organizations failing to keep all of their computers and software up to date with the latest security updates. Keeping your systems up to date costs NOTHING, the manufacturers send out these updates for free. This can be one of the most important steps you take to protect the data in your practice.
