WiFi網絡好處多 資訊保安莫忽略
自當局公佈WiFi無線上網計劃後,業界一直非常關注計劃的進展,包括計劃的分項開支、服務模式以及資訊保安的問題等,就此筆者亦曾去信要求當局提供更多資料。最近,當局提交設立公用WiFi無線網絡的資料文件,並將建議撥款額修訂為二億二千七百五十萬,以便向公眾提供WiFi無線上網服務。這筆款項將包括設立網絡基建及過濾軟件、進行系統評估、互聯網連接費、支援及保養以及協助市民使用WiFi上網服務的服務台等開支。
當局將會在三百五十多個政府場地安裝約三千個WiFi無線熱點,即平均每個場地將安裝九個熱點。有業界人士擔心政府場地附近的居民由於可接收免費WiFi服務的訊號,將可能放棄互聯網營辦商的上網計劃,因此損害他們的利益。就此筆者曾向當局了解WiFi上網服務的細節,得知WiFi上網服務將會與所屬場地的開放時間一致,同時亦會加入使用時間上限,相信這些措施能有助減輕對互聯網營辦商的影響。
另外,資訊保安問題引起了業界廣泛關注,特別是於無線網絡上執法的問題。現時執法部門須根據於網上進行不法活動人士的所使用的IP地址,並配合互聯網商的客戶資料,方有機會追查到涉案人士的身份。可是IP位址在無線上網的環境下並非固定,而當局亦沒有網絡用戶的資料,因此現行執法模式並不適用。
筆者曾參與業界人士討論,其中資訊保安專業人士擔心政府提供的WiFi服務將變相提供途徑讓市民進行不法行動,包括使用Peer-to-Peer技術下載侵權物品。他們建議當局應設立用戶註冊系統,以協助執法機關追查用戶身份,各網絡熱點亦應保存用戶使用記錄,以便在有需要時能識別用戶的身份。另一方案則是要求用戶登記其網絡卡的MAC(Media Access Control)地址,由於每張網絡卡均有其獨一無異的MAC地址,有關記錄亦可協助執法機關追查涉案電腦,從而識別涉案人士的身份。
可是亦有業界人士提出相反意見。他們擔心由於登記程度可能涉及個人資料及需要一定的技術知識,註冊系統將會令無線上網服務難以使用。市民可能會因此望而卻步,令計劃失卻向市民推廣新科技的原意。
由於當局並無計劃設立任何用戶登記系統,筆者促請當局應考慮業界的意見,在資訊保安和便利市民這兩個因素間取得平衡,以達到鼓勵市民採用新科技的目標。立法會財務委員會將於稍後時間審核這項撥款建議,並決定是否批准撥款進行這項工程。筆者促請政府於財委會上交代如何處理上述問題,令這項計劃能真正使社會各界受惠。
