公共無線網絡其実有危險，日本人認知度低

A few weeks ago the Yomiuri News on-line reported the following:

実は危険な公衆無線ＬＡＮ、日本人の認識低く

2015年03月15日 14時38分

　観光地でインターネットに無料で接続できる公衆無線ＬＡＮについて、日本人が訪日外国人客に比べ、通信内容の盗み見などの危険性を認識していないことが、総務省のアンケート調査で分かった。

　対策を実施していると答えた人は半数以下にとどまり、総務省は注意を促している。

　無料の公衆無線ＬＡＮの多くは通信が暗号化されておらず、第三者に内容を見られたり、盗聴されたりする危険性がある。調査の結果、こうした危険性について認識している人の割合は、訪日外国人で８５・３％に上ったのに対し、日本人は６４・８％と低かった。

　セキュリティー対策ソフトの利用や、パスワード、クレジットカード番号といった重要な情報をやりとりしないなど、何らかの対策をしている人の割合も日本人は４７・１％だった。訪日外国人客（７２・０％）に比べて意識の低さが目立った。

A questionnaire survey by the Ministry of Public Management, Home Affairs, Posts and Telecommunications showed that, about public wireless LAN which could connect to the Internet free of charge at tourist spots, compared with foreigners visiting Japan, the Japanese did not recognize the danger that communication contents could be spied on.

  The number of people who answered that they had taken precautions was less than half, and the Ministry of Public Management, Home Affairs, Posts and Telecommunications was calling for attention.

  Many communications using the free public wireless LAN were not coded, the contents could be seen by a third person and there was a danger of being tapped. In the investigation result, the percentage of people who knew about such danger went up to 85. 3% for foreigners visiting Japan and it was as low at 64.8% for the Japanese.

  On measures using security software, or not to exchange important information such as passwords and credit card numbers, the percentage of people who had taken some measures was 47.1% for the Japanese, clearly showing a low consciousness compared with the foreigners visiting Japan (72.0%).

So I think the Japanese government needs to do something to educate the people.
