Hurray! I have passed!

HURRAY!

I've passed the 2nd year of my MSc in Computer Systems Security at Glamorgan University

I achieved 7 out of 8 distinctions for the assignments giving a total of 4 modules distinction, 1 module merit and 1 at pass grade.

I've now just got to do the final year dissertation.

MS08-067 As used by Conficker and Stuxnet

How do Worms travel?

Strictly speaking, a computer virus doesn't spread across a network whereas a computer worm can travel from machine to machine. But how do worms move between machines?

A vulnerability with the catchy name of MS08-067 was used by Stuxnet and Conficker to worm themselves across Local Area Networks but how did it work?  I spent a reasonable amount of time reverse engineering the vulnerability to discover how it was exploited. 

Dangers of Open Wi-fi Hot Spots

Open and free Wi-Fi spots sound great - internet anywhere!  But what are the IT security dangers?

The Importance of Passwords

Imagine what the world would be like if all the keys and locks were the same?

It would mean that you wouldn't need to remember which key goes where - you just pick up one key and can use it to lock-up your own house, visit granny without waking her up, surprise a few friends by calling in unannounced and look after the neighbour's cat while their on holiday. But there is a problem!

Is email secure?

In one word “No” email is not secure!

If it is used to transmit personal details, especially things like bank account details - even to a trusted friend or organisation - it is comparable to posting the same details on the side of a bus with a message saying "FREE MONEY HERE!"
