Misleading Certificates

Posted by Robert Schifreen on March 12, 2016

I’ve been training people in security awareness for a long time now. It’s how I make my living. One of the topics I always cover is how to use the web safely. You’ll notice that I refer to using the web, rather than browsing it. That’s because the web nowadays is a two-way process. We […]

CISSP Study Guide Reviewed

Posted by Robert Schifreen on January 7, 2016

I’ve always been a bit cynical when it comes to professional IT qualifications.  They have their values, for sure, but you need to be sure that the certification you’re studying for, or recruiting against, isn’t merely a marketing ploy by a vendor.  Sure, you can be pretty confident that someone with a Microsoft or Cisco […]

Nessus Cloud

Warning – Broken Firewall Ahead

Posted by Robert Schifreen on August 8, 2015

I’ve spent the past couple of days trying to make a Billion router (specifically a model 7800DX) act in a vaguely secure manner.  This has proved way more difficult than it should be, and I think it has some worrying implications for anyone who uses this hardware in the expectation that it’s protecting their network.

The Sticky Problem Of Public Passwords

Posted by Robert Schifreen on May 2, 2015

Close your eyes. Let me take you back in time for a moment. It’s 1985. I’m into hacking and you’re an IT manager. You ask me how I manage to break into all those computers. Is it, you wonder, because I’m a really clever hacker who knows how to defeat the technology?  Actually, no. It’s […]
