密码保护策略
We all know that the more complicated a password is, the better. 它们应该包括各种数字, 标点符号, 符号, 还有大写字母和小写字母. But are these precautions enough to keep your digital information safe?
推特, 雅虎, and LinkedIn have all fallen prey to online attackers who have stolen entire databases full of passwords. 为了安全起见，密码被打乱了, but this offers little comfort when computer programs can make millions of guesses in just a few hours. Because most passwords are based on words in a dictionary combined with a number or symbol, it can take these 复杂的 programs even less time to hack them.1,2
The end result is that common password policies don't prevent the theft of many users' passwords, 这就产生了一个复合体, 复杂的, 以及利润丰厚的影子产业. Believe it or not, stolen passwords can fetch big money on the black market.3
这对你来说意味着什么? It means that every password you’ve created is a valuable and vulnerable commodity worth protecting.
To do so, you should go a step beyond choosing passwords that are hard for a human to guess. Your passwords need to also be difficult for a computer to figure out. 这里有一些建议.
长度胜过复杂度
较长的密码更难破解. 长度建议不少于12个字符. Consider stringing together the first couple letters of a favorite movie quote, song lyric, or poem. For extra-sensitive accounts, it may make sense to change your passwords on a regular basis. If you like the idea of optimal password protection, 但担心你不能处理很多, 频繁更改密码, 密码管理器可以帮助您组织, 商店, 安全使用多个密码.4
没有简单的英语
简单的数字串, along with passwords that can be found in the dictionary, 是最容易破解的吗. A strong password should contain one or more uppercase and lowercase characters, 数字, 符号, 甚至是unicode字符.
混搭
Many people use the same password for multiple accounts because it’s easier to remember. 但这可能会导致严重后果. You may not be too concerned about the personal information 商店d in your LinkedIn or 推特 accounts, but what would happen if hackers used your compromised password to access your email, 经纪公司, 或者银行账户? If you have trouble remembering multiple passwords, 你可能想在你的电脑上保存一个清单, but don’t 商店 it on your desktop or in your inbox. Give the file a misleading name and bury it in a folder where only you can find it.
没有牢不可破的密码这回事. 仍然, putting personal information behind a basic password is like leaving your Porsche in a parking lot with your keys on the dash. By taking preventative measures to strengthen your password, you may be able to help safeguard your sensitive personal data and your privacy.
