I have just completed a 4 day course on SDH (Synchronous Digital Hierachy) thats to do with my work with a major Telecommunications,Digital TV, and Broadband company. Although I cant say too much I thought I was well aware of privacy concerns when it comes to personal information such as email and broadband data transfer, I was wrong. Lets just say that for about the last several years our email privacy is nowhere near as private as we thought,I had my suspicions to snooping but never to this extent. For those unaware of SDH it basically deals with the means and ways that voice and data are transmitted across a 'network' whether locally or internationally. To give you an idea there are several multi billion lawsuits in process with regards to Industrial espionage, so the common man is very insignificant with regards to this. Basically, you can rest assured that every single email sent IS monitored. Obviously not by a team of goons in a dark office but by several floors of equipment running complex algorythymns to poke and pry and scan. Lets just say that I have uninstalled PGP. Please dont ask for any more info,I wont say much more, but dont think this as 'scaremongering' or 'sensationalisation', its fact. May I just add that the protocol involved in the transfer is not specific to my company but to the industry as a whole,this means there must be thousands of people 'in the know' Anyone knowledgeable in SDH (and even PDH= Plesiochronous Digital Hierachy) will be aware of Path Overheads etc and is possibly well aware of what I refer to,if so I would like to hear from them. Addendum: I have been in conversation tonight with my NOM and I am not happy this is going on on such a scale, he has 'advised' me that its not beneficial to my career to 'worry' about it, but I will spend this weekend deciding whether its worth risking my career to expand on it and start the ball rolling with regards to making it more widely known and give full details. Frankly people it has disgusted me enough to risk a career I have had since 17 years old to go with it. I need to discuss things with my family and see, I doubt anything I could say proved anyway and maybe its not worth the grief but at the moment I am seething and when I have cooled down I'll decide.
