12 Simple Things You Can Do to Be More Secure Online

遵循这些简单的提示来保护你的设备的安全, your data, 你的网络流量, 和你的身份.

Updated March 19, 2021

Are you 担心国税局会曝光 您在网上报税时提交的个人资料,或该 DMV可能泄漏 您的所有个人信息? That’s not paranoid; it’s rational. High-level breaches can and do happen, and there’s nothing you can do to prevent them. 但其他对你的安全和隐私的攻击更接近家庭. When you sit down to work on your novel one day, 你可以找到所有现有的章节加密的勒索软件. You might also log into your online banking system and see a big fat zero balance, because a data-stealing Trojan captured your credentials. On the bright side, you can mount your own defense against these local problems.

使您的设备、在线身份和活动更安全实际上并不需要太多的努力. In fact, betway体育的一些建议可以让你在网上更安全,这些建议可以归结为常识. 这些让你在网络生活中更安全的小贴士会让你更安全.

1. Install an Antivirus and Keep It Updated

betway体育称之为这种类型的软件 antivirus, but fending off actual computer viruses is just one small part of what they do. 勒索软件会对你的文件进行加密,并要求支付赎金来恢复它们. Trojan horse programs seem like valid programs, but behind the scenes they steal your private information. Bots turn your computer into a soldier in a zombie army, ready to engage in a denial-of-service attack, or spew spam, 或者其他机器人的命令. 一个有效的反病毒软件可以防止这些和许多其他种类的恶意软件.

In theory, you can set and forget your antivirus protection, letting it hum along in the background, 下载更新, and so on. In practice, you should look it over every now and then. Most antivirus utilities display a green banner or icon when everything is hunky-dory. 如果您打开实用程序并看到黄色或红色,请按照说明让事情回到正轨.

你可能会想,等等,这不是Windows内置的防病毒软件吗? Not only is Microsoft Windows Defender Security Center 融入了操作系统, 它自动接管保护时,它检测不到其他防病毒, 当你安装第三方保护时,就会自动退出. 问题是,这个内置的防病毒软件无法与最好的第三方解决方案相比. Even the best free ones are way better than Windows Defender. Don't rely on it; you can do better.

Whether you've chosen a simple antivirus or a full security suite,你每年都需要续借. Your best bet is to enroll in automatic renewal. 对于一些安全产品,这样做可以保证没有恶意软件. You can always opt out later, if you get the urge to switch to a different product.

One more thing. If your antivirus or security suite doesn't have ransomware保护, consider adding a separate layer of protection. Many ransomware-specific utilities are entirely free, so there's no reason not to try a few of them and select the one that suits you best.

2. Explore the Security Tools You Install

许多优秀的应用程序和设置帮助保护你的设备和你的身份, 但只有当你知道如何正确使用它们时,它们才有价值. To get the maximum protective power from these tools, you must understand their features and settings. For example, 你的智能手机几乎肯定包含一个丢失后找回的选项, 你甚至可能打开了它. 但你是否主动尝试过,以便在需要时知道如何使用?

Most 杀毒工具 have the power to fend off Potentially Unwanted Applications (PUAs), 麻烦的应用程序不是真正的恶意软件,但没有任何好处. But not all of them enable PUA detection by default. Check the detection settings and make sure yours configured to block these annoyances. Likewise, your security suite may have components that aren't active until you turn them on. When you install a new security product, flip through all the pages of the main window, and at least take a glance at the settings.

To be totally sure your antivirus is configured and working correctly, you can turn to the 安全功能检查 AMTSO(反恶意软件测试标准组织)必威betwayapp上的网页. If your antivirus doesn't pass, it's time to contact tech support and find out why.

3. 每次登录都使用唯一的密码

黑客窃取信息最简单的方法之一就是从一个来源获取一批用户名和密码组合,然后在其他地方尝试这些组合. For example, let's say hackers got your username and password by hacking an email provider. 他们可能试图使用相同的用户名和密码组合登录银行必威betwayapp或主要的在线商店. The single best way to prevent one data breach from having a domino effect is to use a 强,独特的密码 for every single online account you have.

Creating a unique and strong password for every account is not a job for a human. 这就是你使用密码管理器的原因. 几个很好的 密码管理器是免费的, and it takes little time to start using one. 然而,付费密码管理器通常提供更多的功能.

When you use a 密码管理器, 您需要记住的唯一密码是锁定密码管理器本身的主密码. When unlocked, the 密码管理器 logs you into your online accounts automatically. That not only helps keep you safer, but also increases your efficiency and productivity. 你不再花时间输入你的登录或处理费时的沮丧重置一个忘记的密码.

4. 找一个VPN并使用它

任何时候,如果你使用的不是你的Wi-Fi网络连接互联网,你应该使用一个 虚拟专用网络或VPN. 假设你去一家咖啡店,连接到一个免费的Wi-Fi网络. 你根本不知道连接的安全性. It's possible that someone else on that network, 在你不知道的, 会开始查看或窃取从笔记本电脑或移动设备发送的文件和数据吗. The hotspot owner might be a crook, sniffing out secrets from all Wi-Fi connections. A VPN encrypts 你的网络流量, routing it though a server owned by the VPN company. That means nobody, not even the owner of the free Wi-Fi network, can snoop on your data.

Using a VPN also hides your IP address. 广告商和追踪者希望通过这个IP地址来识别或定位你,但他们会看到VPN公司的地址. 用VPN欺骗你的位置 另一个国家的服务器也可以解锁在你自己的地区无法获得的内容. 一个更严肃的问题, 压制性国家的记者和活动人士长期以来一直使用VPN技术进行安全通信.

结果是,如果你通过wi - fi连接,不管是在笔记本电脑上, 手机或平板电脑——你真的需要一个VPN. 如果你以前没有用过的话, or the technology sounds a bit beyond your internet savvy, don't worry, betway体育的专题已经覆盖了 如何设置和使用VPN.

5. 使用双因素身份验证

Two-factor authentication can be a pain, but it absolutely makes your accounts more secure. Two-factor authentication means you need to pass another layer of authentication, 不仅仅是用户名和密码, 进入你的账户. 如果帐户中的数据或个人信息是敏感或有价值的, and the account offers two-factor authentication, 你应该启用它. Gmail, Evernote, and Dropbox are a few examples of online services that offer two-factor authentication.

双因素身份验证使用至少两种不同形式的身份验证来验证您的身份:您是什么身份, 你必须, 或者一些你知道的东西. Something you know is the password, naturally. Something you are could mean authentication using a fingerprint, or facial recognition. Something you have could be your mobile phone. 你可能会被要求输入通过文本发送的代码,或者点击手机应用程序上的确认按钮. Something you have could also be a physical Security Key; Google and Microsoft have announced a push toward this kind of authentication.

如果您只是使用密码进行身份验证,那么任何知道密码的人都拥有您的帐户. 启用双因素身份验证时,仅使用密码是没有用的. Most 密码管理器s support two-factor, 尽管有些人只在检测到新设备的连接时才需要它. 必须为密码管理器启用双因素身份验证.

betway体育的特色是谁有 two-factor authentication and how to set it up 能帮你开始吗.

6. Use Passcodes Even When They Are Optional

在任何可用的地方应用密码锁,即使它是可选的. 想想你智能手机上的所有个人数据和连接. Going without a passcode lock is unthinkable.

12 Things to Be More Secure - Passcode

Many smartphones offer a four-digit PIN by default. 不要满足于此. 可用时使用生物特征验证,设置强密码,而不是愚蠢的四位数密码. Remember, even when you use Touch ID or equivalent, you can still authenticate with the passcode, 所以它需要强大.

Modern iOS devices offer a six-digit option; ignore it. Go to Settings > Touch ID & 密码,选择更改密码(或添加密码,如果你没有密码). 如果需要,请输入旧密码. 在屏幕上输入新代码,选择自定义字母数字代码. Enter a strong password, then record it as a secure note in your 密码管理器.

不同的安卓设备提供了不同的设置强密码的途径. 找到设备上的屏幕锁定设置,输入旧的PIN,然后选择密码(如果可用). 和iOS设备一样,添加一个强密码,并将其记录为一个安全提示.

7. 用智能手机支付

信用卡使用系统已经过时,而且一点也不安全. 这不是你的错,但你可以做点什么. Instead of whipping out the old credit card, use Apple Pay or an Android equivalent everywhere you can. There are tons of choices when it comes to apps. 事实上,betway体育有一个完整的综述 移动支付的应用.

将你的智能手机设置为支付设备通常是一个简单的过程. 它通常先拍一张信用卡的照片,你将用它来备份你基于应用程序的支付. And setup pretty much ends there; you're ready.

更安全的12件事- NFC

支持智能手机支付的销售点终端通常会用一个图标来表示, from a picture of a hand holding a smartphone to a stylized representation of a radio wave. Just place your device on the terminal, authenticate with a thumbprint, and you've paid up.

How is that better than using the credit card itself? The app generates a one-use authentication code, good for the current transaction only. 即使有人偷了那代码,对他们也没有任何好处. 用智能手机应用程序支付可以消除数据被盗的可能性 信用卡回收船.

一些智能手机支付应用程序允许你使用类似的一次性代码进行在线支付. 如果你不, 向你的信用卡供应商查询. Typically, 你可以用一个临时号码来代替你真正的信用卡, and the charges go to your regular account. 临时卡号到期后将不再工作. The next time your credit card company or bank calls you to try and sell you upgrades, 询问一次性使用卡号.

You can also get the protection of one-use credit card numbers using third-party apps. Abine模糊溢价, for example, can mask credit card numbers, email addresses, and phone numbers. You shop and communicate as always, but the merchant doesn't receive your actual information.

8. 为不同类型的帐户使用不同的电子邮件地址

那些在安全问题上高度有条理和有条理的人通常会出于不同的目的使用不同的电子邮件地址, to keep the online identities associated with them separate. 如果一封声称来自你银行的钓鱼邮件进入了你仅用于社交媒体的账户, 你知道这是假的.

Consider maintaining one email address dedicated to signing up for apps that you want to try, but which might have questionable security, or which might spam you with promotional messages. After you've vetted a service or app, sign up using one of your permanent email accounts. 如果专用帐户开始收到垃圾邮件,关闭它,并创建一个新的. 这是你从阿比娜·Blur和其他一次性邮件账户服务那里收到的屏蔽邮件的diy版本.

许多必威betwayapp把你的电子邮件地址等同于你的用户名,但有些必威betwayapp让你选择自己的用户名. Consider using a different username every time—hey, your 密码管理器 remembers it! Now anyone trying to get into your account must guess both the username and the password.

9. 明确你的缓存

永远不要低估浏览器缓存对你的了解. Saved cookies, saved searches, and Web history could point to home address, 家庭信息, 以及其他个人数据.

12 Things to Be More Secure - Clear Browser

为了更好地保护那些可能潜伏在你的网络历史中的信息, be sure to delete browser cookies and clear your browser history on a regular basis. It's easy. In Chrome, Edge, Firefox, Internet Explorer, or Opera, 只需按下Ctrl+Shift+Del,弹出一个对话框,让你选择哪些元素的浏览器数据,你想要清除.

删除cookies可能会给一些必威betwayapp带来麻烦——你可能会丢失你申请的任何个性化信息. Most browsers let you list favorite websites whose cookies shouldn't be tossed.

要获得一个完整的入门指南,你可以阅读betway体育的专题 how to clear your cache in any browser.

10. Turn Off the 'Save Password' Feature in Browsers

Speaking of what your browser may know about you, 大多数浏览器都有内置的密码管理解决方案. We at PCMag don't recommend them, however. We feel it's best to leave password protection to the experts who make 密码管理器s.

想想这个. When you install a third-party 密码管理器, 它通常提供从浏览器存储中导入密码的功能. If the 密码管理器 can do that, you can be sure some malicious software can do the same. In addition, 将您的密码保存在一个单一的, 中央密码管理器允许您跨所有浏览器和设备使用它们.

11. Don't Fall Prey to Click Bait or Phishing Scams

确保你的网络生活安全的一部分就是对你点击的内容保持明智. “点击诱饵”指的不仅仅是猫的视频剪辑和吸引人的标题. 它还可以在电子邮件、通讯应用程序和Facebook上包含链接. 钓鱼链接伪装成安全必威betwayapp,希望骗你把你的证书给他们. Drive-by download pages can cause malware to automatically download and infect your device.

Don't click links in emails or text messages, unless they come from a source you trust. Even then, be cautious; your trusted source might have been compromised, 或者消息可能是假的. 社交媒体必威betwayapp上的链接也是如此,即使是那些看起来像是来自朋友的帖子. If a post seems unlike the style of your social media buddy, it could be a hack.

12. 保护你的社交媒体隐私

There’s a common saying: if you’re not paying for a service, you’re not a customer; you’re the product. Social media sites make it easy for you to share your thoughts and pictures with friends, but it’s easy to wind up sharing too much.

You can 下载你的Facebook数据 to see just what the social media giant knows about you. 这可能会让你大开眼界, 特别是如果你是那种经常点击需要使用社交媒体账户的小测验的人. 真的,你不需要知道你是哪个迪士尼公主或狗的品种.

你可以通过以下方法大幅减少访问Facebook的数据量 禁用共享平台 entirely. 一旦你这样做了,你的朋友就不能再泄露你的个人数据了. You can't lose data to apps, because you can't use apps. 而且你不能用你的Facebook账号登录其他必威betwayapp(这总是一个坏主意).

Of course, other social media sites need attention too. 谷歌可能比Facebook更了解你,所以请采取行动 管理您的谷歌隐私, too. Make sure you've configured each social media site so that your posts aren't public (well, 所有Twitter除外). 在发布太多信息之前要三思,因为你的朋友可能会和别人分享. 小心点,你可以在不失去社交媒体的娱乐和联系的情况下保留你的隐私.
