  • As humans we like to focus too much on the “Why me? Why would they do this? Why my site?” but the reality is that we rarely do what we have to from the get go. How many of those same people asking the “Why” spent the time asking the “How” before they got a website.I know I didn’t….By How I mean, how do I protect myself? This ofcourse is not fault to you as website owners. It just hasn’t been instilled in our brains yet. When you buy a car, before you get off the lot the sales person is telling you about insurance and things like GAP. When you buy a computer, they come with builtinAntiVirus, offering 6 months free, and making it difficult for you to get rid of later. The reality, these are very annoying pesky examples but it puts it in our minds. We need insurance. We need an antivirus. Can we say the same for when we are building a website or when we’re requesting it? Can we say that we’re asking our developers and maintainers the right questions?

Its intent is to provide redundancy in the event a security control fails or a vulnerability is exploited…”
  • KNOW THE ENVIRONMENTLAMPSTACK LINUX Apache MySQL PHP • This is what it takes to run WordPress • Each contains its own laundry list of known vulnerabilities • .org Implementations not .com 3/15/2014@PEREZBOX @SUCURI_SECURITY #WCCHX 7

  • • Website Firewall – SaaS based • Stay current with the latest vulnerability releases • Apply updates to entire stack when available • Keep Only What you need on the server (production) • Very difficult for non technical people • Users refuse to update, some cannot • Soup Kitchen Servers • Too many attackers with too much time • Zero Days SOFTWARE VULNERABILITIES Challenges Solutions 3/15/2014@PEREZBOX @SUCURI_SECURITY #WCCHX 12
