VPN とは何でしょうか? また公衆 Wi-Fi ではなぜ VPN を使用すべきなのでしょうか?

フリー Wi-Fi の安全性を疑ったことはありますか? このような疑問を感じているのはあなただけではありません。「Norton Cybersecurity Insights Report(英語) によると、米国では10 人中 6 人の消費者は、フリー Wi-Fi を使用するのは公衆トイレを使用するより危険と考えています(アメリカでは公衆トイレは危険な場所とみなされています)。そして実際に危険なのです。セキュアでない Wi-Fi ネットワークで Web の閲覧や情報のやりとりを行うと、自分の個人情報や匿名性を危険にさらすことになります。オンラインセキュリティやプライバシーが気がかりな人にとって仮想プライベートネットワーク (VPN) が必須であるのはこのためです。

VPN とは?

仮想プライベートネットワークは、公衆のインターネット接続からプライベートネットワークを構築することにより、オンラインでのプライバシーや匿名性を確保します。VPN IP (Internet Protocol) アドレスをマスクするため、オンラインでの活動が事実上追跡不可能になります。さらに重要な点として、VPN サービスでは、セキュアで暗号化された接続を確立することにより、セキュアな Wi-Fi ホットスポットよりも強力なプライバシーが保証されます

VPN はなぜ必要か?

外出先でのことを思い出してください。コーヒーショップに並んでいる間、電子メールを読んだり、病院で待っている間に口座を確認したりしたことはありませんかパスワードが必要なプライベート Wi-Fi ネットワークにログインしていたのでない限り、オンラインセッション中に送信されたすべてのデータは、同じネットワークを使用していた他人に傍受されていた可能性があります

VPN が提供する暗号化と匿名性は、電子メールの送信、オンラインでの買い物、支払いなど、オンラインでのあらゆる活動を保護します。また VPN Web 閲覧の匿名性も保ちます

セキュリティ以上の利点

VPN は基本的に、ローカルネットワークと別の場所にある出口ノードとの間にデータトンネルを構築します。この出口ノードは数千キロ離れている場合もあり、あたかもあなたが別の場所にいるかのように見えます。このような利点により、特定の Web サイトへのアクセスが検閲される国に住む人にとって、VPN は非常に重要です。また VPN は、世界中のどこからでも、まるで自宅にいるかのように、お気に入りのアプリや Web サイトを使用し続けることを可能にします

VPN の選択方法

公衆 Wi-Fi を安全に使用する最適な方法は、ノートン WiFi プライバシーのような VPN ソリューションを使用することです。VPN プロバイダの選択時には、以下の点を確認してください

  1. プライバシーは尊重されているか? VPN を使用する目的はプライバシーの保護であるため、VPN プロバイダによってもプライバシーが尊重されていることが不可欠です。プロバイダはログなしポリシーを採用している、つまりオンライン活動の追跡やログへの記録を行っていないことが重要です。
  2. 最新のプロトコルが使用されているか? OpenVPN は PPTP などの他のプロトコルよりも強力なセキュリティを提供します。
  3. データ制限は設定されているか? インターネットの使用量によっては、帯域幅が大きな決定要因となるでしょう。データ制限がなく、帯域幅が使い放題であるかどうかを調べ、プロバイダのサービスが自分のニーズに合っていることを確認します。一部のアプリでは無料である代わりに広告が頻繁に表示されることがあるので注意が必要です。
  4. サーバーはどこに置かれているか? サーバーの配置場所として、自分にとってどこが重要であるかを考慮します。特定の場所から Web にアクセスしているように見せたい場合は、その国にサーバーがあることを確認します。
  5. 複数のデバイスでの VPN アクセスの設定は可能か? 平均的な消費者であれば、3 ~ 5 台のデバイスを使用しているでしょう。それらすべてのデバイスで同時に VPN を使用できることが理想的です。
  6. VPN がダウンした場合はどうなるか? プロバイダが障害発生時に備えてキルスイッチシステムを実装していることを確認します。つまり、何か問題が発生した場合には、接続が自動的にロックダウンされ、セキュアでないインターネット接続がデフォルトで使用されないようにすることが重要です。

VPN プロバイダの選択時にはさまざまな点を考慮する必要があるため、自分のニーズに最適なサービスが得られるよう、十分な下調べを行ってください。どのプロバイダを選択した場合でも、優れた VPN であれば、どんなフリー Wi-Fi ホットスポットよりもはるかに強力なオンラインでのプライバシーおよび匿名性が提供されることは間違いありません

Yes, VPN is good, but very often even when you use VPN, it is possible to single out your real IP address. Before going online at work we check the anonymity via 2ip.io/privacy/ . The system will try to single out your real IP and if it doesn't - you can safely go online

I chat asked Norton about this and the answer is apparently NO, you have to purchase a Norton wi fi privacy vpn app for the vpn protection when using hotspots while traveling. At home you have vpn protection through your internet service. That's $29... extra a year per device currently. And it is for Apple and Android only platforms.

I'm confused ....

I subscribed to "Norton Hot Spot" (NHS) some time back and in the middle of my subscription ... I was informed that the NHS product was being discontinued and I needed to migrate to an offering by another company:  Hotspot Shield by AnchorFree.

Is Norton back in the game? 

what's going on?

If I plan on replacing it, how can I tell in advance what mobile is compatible with Norton products?

Thanks.

I would go to Norton chat on your account before you replace anything to see what they actually cover. Because it is a lot of money for these devices only to find they are not compatible like the fire tablets. I do not get why a Norton person has not answered any of the questions on this site- so I use the chat option n my account. Currently Norton is supporting android and apple products however not many amazon fire. And google stuff does not work on fire.

At the moment, I'm online at home, however, I have gone to the main branch library and church with my laptop and it would be great to use the WiFi access without wondering if someone is piggybacking of my signal and looking at my laptop's contents.

I use ExpressVPN. I did a lot

拍手0

I use ExpressVPN. I did a lot of research on VPNs and this one was given the highest marks. It works very well for me, and you can put it both on your phone and on your laptop. It is a paid service; for 12 months, it's $9/month. Well worth it. Norton's new product is only half a loaf. And we're all still waiting for some Nortonite to respond to all these messages. If Norton were really all that concerned about your laptop's security, they would at least give you some useful information about how to do that, if they do not have such a product themselves. And why don't they? Beats me. ExpressVPN does the trick.

A fun aside: I'm what's called a "Russia hand." I managed a lot of our science cooperation with the USSR and later. 20 years ago, I met a very nice Russian couple in Moscow who were both computer programmers who told me that they worked in a secret facility (the Russians call it a "yashchik," literally a "post office box"). They had a dog. They named the dog "Norton." I actually thought that was a pretty good endorsement for Norton and I've used it ever since. But then again, there's that dog. What were they thinking? Go figure.

If a WiFi connection at a hotel is secure, would I still need the Norton WiFi Privacy or would the secure connection at a hotel be enough security to be able to type in sensitive data, such as passwords and credit card information? Also, if a hotel does have a secure connection, does this mean that the hotel is using a VPN? Thank you.

Hotel connections for guests

拍手1 統計
Hotel connections for guests are never secure, and they do not use VPN for such connections. If you're concerned about privacy, you should use a VPN. And if you're using a laptop and not your phone, Norton's current app will not help. Use EXPRESS VPN or something similar. And once Norton comes out with something for laptops, compare prices.

Thank you for your response.

Thank you for your response. This information is helpful because last year I was at a hotel and a family member had just bought his first ever Android smartphone. When we were deciding if we should order pizza through a website, we decided against it because we weren't sure if it was safe. I am so glad that we listened to our instincts! I like the article you linked too. Please keep up with these informative articles. They are generally easy to read even for people like me who are not technically informed. They are very helpful and the information could help prevent a lot of future aggravation for smartphone and computer users.

I think the reason is: Your Internet service provider does not agree an another SMTP as his.

How to prevent android apps

How to prevent android apps going online before Norton VPN makes a secure tunnel?
(on my android every time I switch-on the "wifi", during the time needed to Norton VPN to build up the tunnel, I can clearly see all my apps notifications appear, which means...  a lot of traffic has been exchanged "in clear"!!)
