How to Protect Online Privacy?如何保護(hù)網(wǎng)絡(luò)隱私？

尼基·霍塞克 譯/劉安琪 Nicky Hoseck

It might be tempting to forget the warnings that told us， “Data is the new gold”， but with reporters still emphasizing that he who owns data owns the future， maintaining some level of online privacy is a must.

In this article， were going to give you some ideas and tips about how to best protect your privacy online and retain control over your financial and personal information.

1. Use a password manager to protect yourself

The average person has 70—80 passwords to remember. As a result， many of us end up reusing the same old passwords or relying on passwords that are easy to remember， but equally easy to guess.

A password manager gives you a safe place to store your passwords while monitoring their weakness and repetition and helping you create new， strong passwords. Many password managers are free， up to a point at least.

2. Use a VPN1 to stay safe on public networks

Public Wi-Fi networks are the virtual equivalent of the dodgy neighborhood， where cybercriminals， hackers， and other nefarious characters are loitering on every corner. Using a public Wi-Fi connection exposes you to a variety of cyber threats.

An unsecured public Wi-Fi connection could redirect you to a malicious website. Even if you only visit secure HTTPS2 sites， some of the apps on your cell phone could be connecting to HTTP3 sites without you knowing it. If youve not installed the latest security patches for your operating system， your device could come under attack.

3. Use a private browsing mode when surfing the web

While a private browsing session4 doesnt offer the same level of security as a VPN， it does mean your browsing history wont be saved and any cookies generated during the session， deleted.

Private browsing mode is “l(fā)argely ineffective at blocking third-party monitoring， meaning that your internet service provider can still track your online activities”. It will， however， stop anyone else using that device from finding out where youve been or accessing sensitive information， like your online banking password.

Its a step in the right direction but， if you want to protect your privacy online more effectively， you could try using an anonymous browser， or let a VPN shroud you in a cloak of anonymity.

4. Stop adware by using an ad blocker

Adware was sent to try us. It may be designed to gather information so we only see relevant adverts in our social media feeds， but its gone way beyond the call of duty5.

Some adware is so persistent， it will follow you through cyberspace， tracking your digital footprint and gathering up crumbs of information about your location. Once its finished， it will? ? ? ?inundate6 you with adverts that interrupt your browsing experience， devour your mobile data， and eat away at7 your devices battery life.

Standalone adblockers like AdBlock Plus and uBlock Origin， are available as free browser extensions and some antivirus software and VPN providers bundle8 ad blockers into their suite of cybersecurity tools.

5. Update your privacy settings on social media account

You may have， inadvertently， given all sorts of apps and websites permission to interact with Facebook using your profile. You can， if you have a morning to spare， use Facebooks Off-Facebook Activity tool to track them down and close them down but， I warn you， its not easy but it is worth it.

Its advisable to tweak a few settings to improve your online privacy. These include：

· Not using location data when posting

· Preventing users from tagging you in photos

· Hiding your email address and phone number

· Turning off personalization and data

· Not giving Twitter permission to access your address book

6. Turn off your location

Turning your location on your cellphone is understandable if youre looking for a specific address or want to find the nearest coffee shop. Once youve found what you were looking for， however， you should turn your location off again.

Leaving it open could mean giving unknown companies and peeping Toms9 more insights into your life that youd give your best friend.

Turn your location off or use a VPN to hide it behind a fake IP address. That youll both protect your privacy online and opt out of “the greatest trick technology companies ever played”—“persuading society to surveil itself”.

7. Limit your applications access to personal data and settings

Before you agree to an app collecting data or monitoring your whereabouts， think about whether it really needs that information to operate—and whether you want to share it.

Some apps are rather more cagey. The Washington Post ran an article pointing out that， on the average iPhone， apps are using trackers to collect and share around 1.5GB of data over 30 days.

While you can stop them to some degree by limiting their access， a more effective solution is to install a different type of app altogether—one that will stop trackers instead of activating them.

8. Encrypt your emails

Almost all popular messaging apps use encryption， and yet few of us consider seeking out an encrypted email service. Instead， we seem content to deal with the spam and the phishing attacks， relying on our wits and good sense to filter out the dangers.

Depending on who your email service provider is， you should be able to encrypt emails yourself. To achieve this， however， both you and your recipient need to enable S/MIME10 email encryption settings， so its not viable in every instance.

Alternatively， you could use a third-party encryption tool to do the job for you.

9. Avoid clicking on links from unknown sources

Phishing is a virulent strain of social engineering11 and phishing emails usually try to entice the recipient into clicking on a link or opening an attachment. The best way to stop them is by， quite simply， not clicking on or opening anything that is not from a reliable source.

You should never reveal personal information via email unless you are absolutely sure who you are sending it to.

While some antivirus packages will guard against phishing attacks， the most reliable way of protecting your online privacy in this instance12， is by constant vigilance and awareness.

10. Manage your smart devices

Having your fridge chatting away to your home thermostat is great if you want to control temperatures， but terrible if you want to control your data flow. If you put all your devices onto the same network， its the virtual equivalent of putting all your eggs into one basket.

As the FBI warned， “your fridge and your laptop should not be on the same network”. That way， if someone hacks your fridge， they wont immediately gain access to your laptop as well. You could also add a VPN to your router and encrypt all the data thats flowing through your IoT devices.

人們也許很容易忘記“數(shù)據(jù)是新的黃金”這樣的忠告，但既然記者仍在強(qiáng)調(diào)誰(shuí)擁有數(shù)據(jù)誰(shuí)就擁有未來(lái)，那么在網(wǎng)絡(luò)上保持一定程度的隱私還是有必要的。

如何最妥善地保護(hù)網(wǎng)絡(luò)隱私，以及如何牢牢掌握自己的財(cái)務(wù)和個(gè)人信息，本文將為你提供一些想法和建議。

1. 使用密碼管理器保護(hù)自己

一般人需要記住的密碼有七八十個(gè)。因此，很多人到頭來(lái)都會(huì)重復(fù)使用相同的舊密碼，或是依賴那些容易記住的密碼，但后者也同樣容易被人猜出來(lái)。

密碼管理器提供了一個(gè)安全的空間來(lái)存儲(chǔ)密碼，同時(shí)還可以監(jiān)控其安全性和重復(fù)性，并幫助創(chuàng)建安全性強(qiáng)的新密碼。許多密碼管理器都是免費(fèi)的，至少一定程度上是免費(fèi)的。

2. 在公共網(wǎng)絡(luò)使用虛擬專用網(wǎng)絡(luò)（VPN）保障安全

公共無(wú)線（Wi-Fi）網(wǎng)絡(luò)實(shí)際上相當(dāng)于一個(gè)危險(xiǎn)的小區(qū)，每個(gè)角落時(shí)時(shí)都游蕩著網(wǎng)絡(luò)犯罪分子、黑客和其他不道德的人。連上公共Wi-Fi會(huì)面臨各種各樣的網(wǎng)絡(luò)威脅。

連接未經(jīng)加密的公共Wi-Fi有可能跳轉(zhuǎn)到惡意網(wǎng)站。即使只訪問(wèn)安全的超文本傳輸安全協(xié)議網(wǎng)站，手機(jī)中的一些應(yīng)用程序也可能會(huì)在不知不覺(jué)中連接到超文本傳送協(xié)議網(wǎng)站。如果尚未給操作系統(tǒng)安裝最新的安全補(bǔ)丁，你的設(shè)備就可能會(huì)遭受攻擊。

3. 上網(wǎng)時(shí)使用無(wú)痕瀏覽模式

無(wú)痕瀏覽提供不了與VPN相同的安全程度，但它確實(shí)意味著瀏覽歷史不會(huì)保存下來(lái)，并且瀏覽期間生成的所有緩存文件都會(huì)被刪除。

無(wú)痕瀏覽模式“在攔截第三方監(jiān)控方面很大程度上是無(wú)效的，這意味著互聯(lián)網(wǎng)服務(wù)提供商仍然可以跟蹤你的在線活動(dòng)”。但是，無(wú)痕瀏覽模式可以阻止使用該設(shè)備的其他人發(fā)現(xiàn)你訪問(wèn)過(guò)什么網(wǎng)站或者找到你的網(wǎng)上銀行密碼等敏感信息。

采用無(wú)痕瀏覽模式是正確的，但如果想要更加有效地保護(hù)網(wǎng)絡(luò)隱私，可以嘗試使用匿名瀏覽器，或是用VPN為你披上一件匿名的外衣。

4. 使用廣告攔截器攔截廣告軟件

廣告軟件是被派來(lái)試探我們的。它可能用于收集信息，目的是讓我們?cè)谏缃幻襟w信息流中只看到與我們有關(guān)的廣告，但廣告軟件所做的已超出了它們的職責(zé)范圍。

一些廣告軟件非常頑固，它會(huì)在網(wǎng)絡(luò)空間跟蹤你，追蹤數(shù)字足跡，收集點(diǎn)點(diǎn)滴滴的位置信息。這些軟件一旦完成信息收集，就會(huì)將你淹沒(méi)在廣告之中，打斷瀏覽體驗(yàn)，吞噬移動(dòng)數(shù)據(jù)，還會(huì)消耗設(shè)備電池壽命。

AdBlock Plus和uBlock Origin這樣的獨(dú)立廣告攔截器都是瀏覽器擴(kuò)展程序，可以免費(fèi)獲取。還有一些殺毒軟件和VPN提供商在他們的網(wǎng)絡(luò)安全工具套裝中免費(fèi)贈(zèng)送幾款廣告攔截器。

5. 更新社交媒體賬戶的隱私設(shè)置

也許不經(jīng)意間，你已向各種應(yīng)用程序和網(wǎng)站授權(quán)，準(zhǔn)許使用你的個(gè)人資料與臉書交互。如果能抽出一個(gè)上午的時(shí)間，你可以使用臉書的“站外活動(dòng)”工具來(lái)追蹤這些授權(quán)并關(guān)閉它們。我得提醒你，這么做并不容易，但值得一做。

最好調(diào)整一些設(shè)置來(lái)增強(qiáng)對(duì)網(wǎng)絡(luò)隱私的保護(hù)。這些設(shè)置包括：

·發(fā)帖時(shí)不使用位置數(shù)據(jù)

·禁止用戶在照片中標(biāo)記你

·隱藏電子郵件地址和電話號(hào)碼

·關(guān)閉個(gè)性化設(shè)置及其數(shù)據(jù)

·不授權(quán)推特訪問(wèn)通訊錄

6. 關(guān)閉定位功能

如果你在尋找一個(gè)特定的地址或是想要找到最近的咖啡館，那么打開(kāi)手機(jī)定位是合理的。然而，一旦找到了要找的地點(diǎn)，就應(yīng)該重新關(guān)閉定位。

如果一直開(kāi)著定位，陌生公司和偷窺狂就有機(jī)會(huì)更多地窺探你的生活，而這些內(nèi)容你只會(huì)和好朋友分享。

關(guān)閉定位功能，或使用VPN將定位隱藏在假的IP地址背后。這樣既能保護(hù)網(wǎng)絡(luò)隱私，又能選擇退出“各個(gè)科技公司耍過(guò)的最大的把戲”，那就是“說(shuō)服社會(huì)自我監(jiān)視”。

7. 限制應(yīng)用程序訪問(wèn)個(gè)人數(shù)據(jù)和設(shè)置

在同意某個(gè)應(yīng)用程序采集數(shù)據(jù)或監(jiān)控行蹤之前，想一想它是否真的需要這些信息才能運(yùn)行，以及你是否愿意與它分享這些信息。

有些應(yīng)用程序則更加狡猾。《華盛頓郵報(bào)》發(fā)表的一篇文章指出，普通蘋果手機(jī)中的各種應(yīng)用程序使用追蹤器能在30天內(nèi)收集和分享1.5GB的數(shù)據(jù)。

雖然可以通過(guò)限制訪問(wèn)來(lái)在一定程度上阻止這些程序，但更加有效的解決方案是安裝一種完全不同類型的應(yīng)用程序，這種應(yīng)用會(huì)阻止追蹤器，而不是激活它們。

8. 加密電子郵件

幾乎所有流行的消息應(yīng)用都使用了加密手段，但很少人考慮尋求加密電子郵件服務(wù)。我們似乎滿足于處理垃圾郵件和網(wǎng)絡(luò)釣魚攻擊，依靠我們的智慧和良好的判斷力來(lái)過(guò)濾掉危險(xiǎn)。

你應(yīng)當(dāng)是可以自己對(duì)電子郵件進(jìn)行加密的，這要視電子郵件服務(wù)提供商而定。然而，要實(shí)現(xiàn)加密，你和收件人都需要啟用安全多用途互聯(lián)網(wǎng)郵件擴(kuò)展協(xié)議，進(jìn)行電子郵件加密設(shè)置，所以這種方式并不是在所有情況下都可行。

另一種辦法是，你可以使用第三方加密工具來(lái)完成加密。

9. 避免點(diǎn)擊來(lái)源不明的鏈接

網(wǎng)絡(luò)釣魚是一類有惡意的社會(huì)工程，而網(wǎng)絡(luò)釣魚郵件通常試圖誘導(dǎo)收件人點(diǎn)擊鏈接或打開(kāi)附件。阻止它們的最好方法非常簡(jiǎn)單，就是不要點(diǎn)擊或打開(kāi)任何來(lái)源不可靠的東西。

永遠(yuǎn)不要在電子郵件里透露個(gè)人信息，除非你絕對(duì)確定這封郵件發(fā)給的是誰(shuí)。

雖然一些殺毒軟件包可以防范網(wǎng)絡(luò)釣魚攻擊，但保護(hù)網(wǎng)絡(luò)隱私的最可靠方法還是時(shí)時(shí)謹(jǐn)慎小心、處處保持警惕。

10. 管理智能設(shè)備

如果想要控制溫度，那么將冰箱與恒溫器互聯(lián)起來(lái)當(dāng)然棒極了，但如果想要控制你的數(shù)據(jù)流，那么此類連接就很糟糕了。把所有設(shè)備都置于同一個(gè)網(wǎng)絡(luò)中實(shí)際上相當(dāng)于把所有雞蛋放在同一個(gè)籃子里。

正如美國(guó)聯(lián)邦調(diào)查局警告的那樣，“冰箱和筆記本電腦不應(yīng)該共用一個(gè)網(wǎng)絡(luò)”。這樣，如果有人非法侵入了你的冰箱，他也無(wú)法立即訪問(wèn)你的筆記本電腦。你還可以給路由器加設(shè)VPN，并且對(duì)物聯(lián)網(wǎng)設(shè)備里的所有數(shù)據(jù)進(jìn)行加密。
