Hello Douglas,<div><br></div><div>Thank you for this.</div><div><br></div><div>I am glad to have learnt something today. It seems that the limitations are a advantage when it comes to security issues which can not be discussed in the Open. </div>
<div>Security is Secret therefore one does not have to answer Questions in the open (Oga Nii I am sorry there - no answers on security issues) the fact is in the laboratory everything is open but when it comes to security practice things are different!</div>
<div><br></div><div>While on this, our Dr El was asking openly about what is at risk - I do not think an answer could come out in the open just like that - I am pleased the Answers came out the way they were posted.</div>
<div><br></div><div>Bottom line is, DO NOT TRUST anyone on Security Issues - that is the way I see it. Otherwise, better stay in the Laboratories and not in the open world full a mixture of different 'Characters'.</div>
<div><br></div><div>I do not mean to offend anyone no do I have to apologize to anyone when it comes to those issues. Please keep let us Security issues Secure and on Need to Know Basis.</div><div><br></div><div>BTW I have no security mandate - I am just a beneficiary and user of what we have and out to promote development in this area of economic activity. I would like to maintain my uncompromising position by being Truthfully African! </div>
<div><br></div><div>May I ask my colleagues to feel free to say anything to my opinion as they wish - I will respect all that - thank you in advance.</div><div><br></div><div>Well done one and all - Aluta continua!!</div>
<div><br></div><div>Kind regards</div><div><br></div><div>Yassin </div><div><br></div><div> <br><br><div class="gmail_quote">On 24 October 2012 20:14, Douglas Onyango <span dir="ltr"><<a href="mailto:ondouglas@gmail.com" target="_blank">ondouglas@gmail.com</a>></span> wrote:<br>

</div>I am not sure about SA, but I know about Uganda :-) (where I am from).<br>
The SCADA system isn't supposed to be connected to the Internet ---<br>
but you and I know it is idealistic to think this guideline is being<br>
followed.<br>
<br>
All to often networks supposed to be offline have been compromised by<br>
poor network configurations that allowed access to supposedly offline<br>
networks segments connected to online segments.<br>
<br>
A case in point is Stuxnet in Iran's case. The worm didn't use the<br>
Internet to propagate; instead: ignorance, social engineering and a<br>
host of other techniques were used very successfully to infect<br>
computers and networks that were not supposed to be connected online.<br>
<br>
I guess the take away here is that: it take more than just putting a<br>
computer/network offline to secure it from cyber attacks.<br>

Life is the educator's practical joke in which you spend the first<br>
half learning, and the second half learning that everything you<br>
learned in the first was a joke.<br>
