【明報專訊】Wi-Fi無線網絡在香港日漸普及,電腦、手機隨時隨地都可以利用Wi-Fi上網,但一項調查顯示,本港只有7%的Wi-Fi網絡屬絕對安全,加密程度能真正防止任何黑客入侵,而完全沒有加密的網絡則佔22%。調查機構指出,建立及使用沒有加密或低程度加密的Wi-Fi網絡,有較大可能被黑客入侵及盜用網絡,造成損失。

採加密功能存取點升6百分點

香港無線科技商會及專業資訊保安協會去年底進行「無線網絡保安應用普查」,在港九、新界及維港兩岸,以War Driving方式,偵查全港共30,457個Wi-Fi存取點(Access Point),主要為家用及中小企商用的無線網絡,當中78%的存取點已有採用加密功能,較去年的72%,上升6個百分點。

47%加密方式最快10分鐘破解

不過47%仍使用不大安全的WEP加密方式,最快只需10分鐘便可被破解,有可能被人盜取網絡作非法下載及買賣等,另有24%則選擇使用WPA或WPA2下的TKIP制式,最近亦證實有漏洞,在傳輸資料時可被黑客盜取資料,僅7%使用在目前稱得上「絕對安全」的WPA或WPA2的AES加密制式。調查發現,有32%的Wi-Fi網絡並沒有作出個人化設定,一直都使用出廠設定。

存有重要資料帳戶 籲避免登入

香港無線科技商會副主席方健僑表示,硬件配套有97%已有設定WPA的AES制式,作出高程度加密防止入侵,建議Wi-Fi網絡使用者要盡快做出合適的設定,「幾秒鐘就可以搞掂」。

他又指目前部分智能手機未必支援AES制式,故使用者若要利用Wi-Fi上網,應盡量避免登入存有大量重要資料的電郵戶口及銀行帳戶

[Ming Pao Daily News Bulletin] Wi-Fi network in Hong Kong's growing popularity, computer, mobile phone, you can take advantage of the Internet, but a Wi-Fi survey, only 7% of the Wi-Fi network is absolutely safe, the encryption level can actually prevent any hacker intrusion, and absolutely no encryption of network accounted for 22%. Investigating authorities pointed out that the establishment and use no encryption or low-level encryption Wi-Fi network, there are more likely to be hackers and usage of the network, resulting in the loss.

Mining encryption access point + 6 percentage points

WTIA and professional information security association to the end of the year for "wireless network security application census", in the territory and the Harbour to War Driving, investigative territory were 30,457 Wi-Fi access point (Access Point), mainly for household and small and medium-sized company with wireless networks, 78% of the access point has been used in encryption, 72 percent of last year, representing an increase of 6% compared with last year.

47% encryption fastest 10 minutes break

However, 47% still use the less secure the WEP encryption mode, just 10 minutes to be cracked, there may be people steal network for illegal download and sale and another 24% select use WPA or WPA2 under TKIP standard, which has also recently confirmed vulnerability when data is transferred is a hacker steal data, only 7% used in the current "absolute security" WPA or WPA2 AES encryption format. The study found that 32% of Wi-Fi network has not made any personal settings have been set using the factory.

There is important data consumers to avoid login account

WTIA Vice-Chairman Mr Chao, said the party hardware supporting 97% have set WPA AES standard, high level encryption prevents intrusion, it is recommended that a Wi-Fi network user to make appropriate set as soon as possible, "a few seconds to get things done".

【Ming Pao】 Wi-Fi wireless network in Hong Kong and the increasing popularity of computers, mobile phones anytime, anywhere can use the Wi-Fi Internet access, but a survey showed that only 7% of our Wi-Fi network is absolutely secure, encryption level can really to prevent any hacking, but not encrypted network accounted for 22%. Investigative bodies that build and use no encryption or low-level encryption of Wi-Fi networks, were more likely to hacking and theft of network losses.

Mining encryption access point rise 6 percent

Hong Kong Wireless Technology Industry Association and the Professional Information Security Association late last year, "Application of Wireless Network Security Survey", in Hong Kong, Kowloon, New Territories and Victoria Harbour to War Driving way to detect a total of 30,457 were all Wi-Fi access point (Access Point ), mainly for home and SME business wireless network, of which 78% of the access point has encryption features, 72% higher than last year, up 6 percentage points.

47% of the fastest 10 minutes to crack the encryption method

But 47% is still not safe to use WEP encryption, the fastest 10 minutes can be broken, there may have been stealing and trading network for illegal downloading, etc., and another 24% choose to use WPA or WPA2 under TKIP standard, recently confirmed that there is a loophole in the transmission data can be hackers to steal information, only 7% used in the present be regarded as "absolute security" of the WPA or WPA2's AES encryption standard. The survey found that 32% of Wi-Fi network has not made any personal settings, always use the default setting.
