Data breaches are inevitable heres how to protect yourself anyway

Data breaches are inevitable heres how to protect yourself anywayData breaches are inevitable heres how to protect yourself anywayIts tempting to give up on data security altogether, with all the billions of pieces of personal data Social Security numbers, credit cards, home addresses, phone numbers, passwords and much mora breached and stolen in recent years. But thats not realistic nor is the idea of going offline entirely. In any case, huge data-collection corporations vacuum up data about almost every American without their knowledge.As cybersecurity researchers, we offer good news to brighten this bleak picture. There are some simple ways to protect your personal data that can still be effective, though they involve changing how you think about your own information security.The main thing is to assume that you are a target. Though most individual people arent specifically being watched, software that mines massive troves of data enhanced by artificial intelligence can tar get vast numbers of people almost as easily as any one person. Think defensively about how you can protect yourself from an almost inevitable attack, rather than assuming youll avoid harm.Whats most important now?That said, its unproductive and frustrating to think you must pay attention to every possible avenue of attack. Simplify your approach by focusing on what information you most want to protect.Covering the obvious, keep your software up-to-date. Software companies issue updates when they fix security vulnerabilities, but if you dont download and install them, youre leaving yourself unprotected from malware such as keystroke loggers. Also, be smart about what links you click in your schmelzglas or when browsing the web you could inadvertently download malicious software to your phone or computer, or allow hackers access to your verbunden accounts.In terms of online data, the most important information to protect is your login credentials for key accounts like banking, gover nment services, email and social media. You cant do much about how well websites and companies safeguard your information, but you can make it harder for hackers to get into your account, or at least more than one of them.Reusing login names and passwords is a significant risk.Mihai Simonia/Shutterstock.comHow? The first step is to use a different username and password on each crucial site or service. This can be complicated by sites limits on username options or their dependence on email addresses. Similarly, many sites have requirements on passwords that limit their length or the number or type of characters that they can include. But do your best.The reason for this is straightforward When a bunch of usernames and passwords fall into malicious hands, hackers know its human nature to repeat usernames and passwords across many sites. So they almost immediately start trying those combinations anywhere they can like major banks and email services. A chief information security offic er we know in the banking industry told us that after the Yahoo breach of a few years ago, banking sites were hit with multiple attempts to log in with credentials stolen from Yahoo.Use long passwordsThere has been a lot of research about what makes a strong password which has often led to many people using complex passwords like 7hi5sMyPs4w0rd. But more recent research suggests that what matters much more is that passwords are long. Thats what makes them more resistant to an attempt to guess them by trying many different options. Longer passwords dont have to be harder to remember They could be easily recalled phrases like MyFirstCarWasAToyotaCorolla or InHighSchoolIWon9Cross-CountryRaces.It can be daunting to think about remembering all these different usernames and passwords. Password management software can help though choose carefully as more than one of them have been breached. It can be even safer despite conventional wisdom and decades of security advice to write them do wn, so long as you trust everyone who has access to your home.Use a third line of defenseHave hackers driven us back to the age of the physical key?BautschTo add another layer of protection including against troublesome housemates many sites (Google, for example) let you turn on whats called multi-factor authentication. This can be an app on your smartphone that generates a numeric code every 30 seconds or so, or a physical item you plug into your computers USB port. While they can afford at least some protection, be wary of sites that send you a text with a code that method is vulnerable to interception.With these straightforward steps and the new mindset of thinking like a target who wants to avoid getting hit youll be far less worried when news breaks of the next breach of some companys enormous data files. Bad guys may get one of your usernames, and maybe even one of your passwords so youll have to change those. But they wont have all your credentials for all your online ac counts. And if you use multi-factor authentication, the bad guys might not even be able to get into the account whose credentials they just stole.Focus on whats most important to protect, and use simple but effective methods to protect yourself and your information.W.
