Foiled by a dodgy DNS record

Monday, February 18th, 2008

Last week I had a call from one of IINETs customers who was trying to send me email.

Unfortunately for him, but probably fortunate for me, his aforementioned ISP still had DNS records for my domain which were:

Bogus and

5 years old!!!

 

This got me thinking about how many junk DNS entries exist for domains and what are the implications?

Assuming the poor schmo who received my old fixed IP address from IINET was watching his traffic, he would have seen

  • web requests from any user using their DNS
  • email connection requests for anyone trying to send email to me
  • and possibly much worse

It is a good thing that I am a trusting soul :-)

Security problems to fix

Tuesday, February 12th, 2008

Rather than construct a five hundred page document of the broken components in information technology today, I thought I would start simple.

What is one of the most important challenges facing computer security today?

The answer to this question is different to all people, so I considered what affects people most:

  • Social Engineering
  • Scams and Spam
  • Malicious Software (Malware)
  • Hackers and Cyberstalking

Over the coming months we will explore effective and accessible options for addressing each of the security concerns above.
