If you have a website that sells products online then it is vital that you ensure that the software you use or any applications are always up to date. As a responsible website owner you need to try and keep your customers security in the forefront of your mind. Updates are often created to add in security features to programs and therefore if an update is not done in a timely manner, you may be opening your business up to a cyber-attack. If your website has a content management system, this will also need to be updated. If the content management system is a bespoke one, then it will be up to the team who developed it to keep the code updated and ensure that all the latest security features have been installed on it. Off the shelf CMS systems often notify you when you log in that an update is available and it is then up to you to install it. Make sure that prior to carrying out any updates you ensure that all your data is backed up, in case something goes wrong and you need to reinstall it.
