If you suffer multiple reinfections and your site is one of many in an account, the odds are high that you’re suffering from cross-site contamination.

Cross-site contamination is when a site is negatively affected by neighboring sites within the same account/server due to poor isolation on the server and/or account configuration. This phenomenon is one of the greatest contributors to the VPS/Dedicated/Shared hosting secure or insecure debate.

The Principle of Least Privilege

The Principle of Least Privilege

If you own a website and collaborate with others, the principle of least privilege should never be questioned. It is a computer science principle which has applications and benefits to strengthen your website security posture.

This principle is about:

  • Using the minimal set of privileges on a system in order to perform an action.
  • Granting those privileges only for the time the action is necessary.

Website Application Firewalls (WAF) – Practical Approach to Website Security

Website Application Firewalls (WAF) – Practical Approach to Website Security

In 2016, I shared some thoughts about firewalls in general; their history and purpose in the information security domain. The point of the article was to help website owners differentiate between the types of firewalls they might encounter. Today, I will shift my focus specifically to website application firewalls (WAF).

WAFs are not new, but have been traditionally deployed by large organizations. The SMB space has found renewed focus on WAFs over the past three years.

Accounting for Defense in Depth in Website Security

In the field of Information Security (InfoSec) we like to use the phrase defense in depth. Like many things, it is a borrowed term with roots dating back millennia (216 B.C. – the second Punic war). It’s a term that refers to tactics employed by militaries around the world in which they would deploy layers…
