If you are running WordPress for example then any new release – be it a major version release or a minor one – is likely to include a security update to (try and) keep ahead of the numerous hackers out there. If you leave the version of the software you are running out of date then it is very much open to potential security threats.
A Case Study
An example of this occurred with a new client of mine who came to me with a website in tatters – their hosting provider had taken the website offline as it had become riddled with malware (malicious software).
How did this client not keep their website secure?
The main CMS (Content Management System) they were running was a few versions out of date and they had lots of plugins running that hadn’t been updated either. A virus had found it’s way into one of the plugins and then started spreading about the rest of the site. Eventually there were in excess of 120 files compromised by the various malware that had been inserted and it became a costly and time consuming process cleaning it all up.
For my client it was a good lesson learnt – with a few simple processes (or subscription to my WordPress Software Management service for £60 a year!) it is possible to keep everything up-to-date.
WordPress 4.3 Update
So today then, WordPress is updated again with a new release of version 4.3 – and as you know now – it is always recommended to update any software you have running to the latest version for security reasons, so if you have a WordPress driven website then get to it (but make sure you backup data & database first!)
NB If you are also using the Genesis framework (and why wouldn’t you?!) then MAKE SURE you update that to v2.1.3 FIRST…
