An application or app is the software that sits on top of an operating system on a machine or device and provides functionality. Some examples include mobile phone apps, the Adobe suite, Microsoft, Apple and open source office products.
Like any software, it is important to use applications provided by trusted sources, be aware of permissions to access and use other parts of your machine or device that you may be accepting in downloading any application, and to keep these applications up-to-date. Keeping software up-to-date is also known as ‘patching’.
Patching is an important part of cyber security. When a patch or software update is announced, within hours to days hackers may be able to exploit the vulnerability that software update is fixing.
Larger organisations will have what is called a patching regime in place. This is important in more complex environments where a bad patch could wipe out an organisation.
