All software has undiscovered flaws that can be attack vectors. Luckily, supported Drupal versions have a whole community to work on them. After 2 November 2021, Drupal 8 is unsupported, which means that the risk to your site grows massively, from potential bugs and vulnerabilities that threaten your data.
Remaining on Drupal 8 beyond November 2021 creates four main risks:
Data breaches Large-scale data exfiltration can occur via access to websites that hold this data or link to systems that do, like CRMs.
Unauthorised access into organisation-wide systems and infrastructure Website vulnerability can offer a route into an organisation network via servers or other connected systems. Imagine a chain of privilege being exploited through successive systems, with the public-facing website as an obvious front door that's been left open.
Ransom attacks Access to website data means an attacker can then attempt to blackmail an organisation. Other ways in which organisations are extorted include the threat of continued disruption, denial of service, public embarrassment or data sale.
Website vandalism Attackers change your content for multiple purposes, sometimes via automated tools simply for spam and sometimes for more targeted motives.
Impact of these risks:
Loss of your site, either entirely or due to downtime whilst issues are fixed
Loss of your business critical functionality and any systems integrated into the website
Reputational damage that destroys trust in your brand and market confidence. TalkTalk’s market value halved after one such attack.
Data breaches of payment, user and customer data held on the site, or associated systems and subsequent fines. Such as British Airways’ £20m fine for losing customer information.
You can mitigate these risks now:
Keep your Drupal site up to date. Drupal 9 is an upgrade is not a rebuild, so the process measured in days, not months.
Leverage the mature security programme, and updates for Drupal itself and your contributed modules.
Drupal 8 website needs to be updated to Drupal 9. Drupal 8 is reaching end of life, so security updates will only be released for Drupal 9 and Drupal 7 after November 2021.
Update the PHP used on your site hosting alongside Drupal by December 2021.
Work with a trusted digital partner, like NDP Studio, who manages this process for you.
Updates will always be necessary, but Drupal 9 will be supported until November 2023 and then after that, a similar update to Drupal 10 will keep your website and infrastructure secure.
