News: 陸客觀光 直搗我神祕網軍禁區

(中國時報 2009/10/17 呂昭隆 台北報導) 原始新聞連結

國安官員透露，五月底，大陸觀光客馬中飛隨團來台參訪，進入台北市基隆路「國軍人才招募中心」後方的管制區拍照，該營區內除有國防部「資電作戰指揮部」外，還有一個更敏感單位，即行政院研考會「技術服務中心」。此單位扮演政府資訊安全把關角色，馬中飛能找到這個鮮少曝光的單位，應非巧合。

據了解，研考會技服中心全稱是「國家資通安全技術服務中心」，任務是提升政府對資安事件應變能力，降低可能造成的損害，如協助事前安全防護、事中預警應變、事後復原鑑識等「技術服務」。

摸清辦公地點 藉觀光情蒐

據這位國安官員透露，「技服中心」抓大陸電腦駭客、網路間諜相當有一套。某次，國安局偵測到有政府高層官員的個人電腦傳出不明檔案，前任局長許惠祐親自出面處理，國安單位即請「技服中心」出馬，發現這位政府高層官員的筆電有四個木馬程式，並告知「有兩個是安徽的，一個是福建的，還有一個是台灣內部的」，相當厲害。據了解，入侵政府網路資訊的駭客或間諜，以大陸所占比例最高，技服中心是政府資安應變的把關者，雙方過招多年，所以能辨識哪些木馬程式是安徽的，哪些是福建的。

這位官員表示，除了軍方，所有政府文官的資安應變，都是「技服中心」負責，事實上，國安與情治單位的資安，也多半找技服中心協助。

研考會技服中心 意外曝光

這位官員表示，馬中飛在前往基隆路的技服中心前，曾去過新店，這不是一般「大陸觀光客」的行程，因為新店有國安局與國防部的電偵單位，特別是能找到不曾在媒體曝光的技服中心，而且還能知道辦公地點就在基隆路國軍人才招募中心後方的管制區內，應該是來台之前就計畫好了。

這位官員研判，馬中飛是來台進行「觀察情蒐」，以前我軍情局初次派遺約聘人員赴大陸情蒐時，也是這樣做。即先分派一些簡單的任務，或是指定到軍事、敏感單位附近拍照，藉由「觀察情蒐」表現，評估是否正式聘用。

馬中飛是五月廿五日下午四時左右侵入營區拍照，被軍方逮捕，經查看數位相機記憶卡，有數張營區標語等照片，隨後移送檢方，高檢署訊後直接將他釋回，馬中飛隨即搭機回大陸。

News: Gordon Brown: I'm proud to say sorry to a real war hero

Gordon Brown: I'm proud to say sorry to a real war hero
The treatment of code-breaker Alan Turing was utterly unfair, says Gordon Brown

This has been a year of deep reflection – a chance for Britain, as a nation, to commemorate the profound debts we owe to those who came before. A unique combination of anniversaries and events have stirred in us that sense of pride and gratitude that characterise the British experience. Earlier this year, I stood with Presidents Sarkozy and Obama to honour the service and the sacrifice of the heroes who stormed the beaches of Normandy 65 years ago. And just last week, we marked the 70 years which have passed since the British government declared its willingness to take up arms against fascism and declared the outbreak of the Second World War.

So I am both pleased and proud that, thanks to a coalition of computer scientists, historians and LGBT (lesbian, gay, bisexual and transgender) activists, we have this year a chance to mark and celebrate another contribution to Britain's fight against the darkness of dictatorship: that of code-breaker Alan Turing.


Computer pioneer Alan Turing, who helped crack German Enigma codes during WWII

Turing was a quite brilliant mathematician, most famous for his work on breaking the German Enigma codes. It is no exaggeration to say that, without his outstanding contribution, the history of the Second World War could have been very different. He truly was one of those individuals we can point to whose unique contribution helped to turn the tide of war. The debt of gratitude he is owed makes it all the more horrifying, therefore, that he was treated so inhumanely.

In 1952, he was convicted of "gross indecency" – in effect, tried for being gay. His sentence – and he was faced with the miserable choice of this or prison – was chemical castration by a series of injections of female hormones. He took his own life just two years later.

Thousands of people have come together to demand justice for Alan Turing and recognition of the appalling way he was treated. While Turing was dealt with under the law of the time, and we can't put the clock back, his treatment was of course utterly unfair, and I am pleased to have the chance to say how deeply sorry I and we all are for what happened to him. Alan and the many thousands of other gay men who were convicted, as he was convicted, under homophobic laws, were treated terribly. Over the years, millions more lived in fear in conviction. I am proud that those days are gone and that in the past 12 years this Government has done so much to make life fairer and more equal for our LGBT community. This recognition of Alan's status as one of Britain's most famous victims of homophobia is another step towards equality, and long overdue.

But even more than that, Alan deserves recognition for his contribution to humankind. For those of us born after 1945, into a Europe which is united, democratic and at peace, it is hard to imagine that our continent was once the theatre of mankind's darkest hour. It is difficult to believe that in living memory, people could become so consumed by hate – by anti-Semitism, by homophobia, by xenophobia and other murderous prejudices – that the gas chambers and crematoria became a piece of the European landscape as surely as the galleries and universities and concert halls which had marked out the European civilisation for hundreds of years.

It is thanks to men and women who were totally committed to fighting fascism, people like Alan Turing, that the horrors of the Holocaust and of total war are part of Europe's history and not Europe's present. So on behalf of the British government, and all those who live freely thanks to Alan's work, I am very proud to say: we're sorry. You deserved so much better.
