In general, be deeply suspicious of desperate requests for help and unsolicited job offers. Scammers often pretend to be relatives or close friends who have gotten into trouble while traveling and require a quick wire transfer. Job offers can sometimes mask attempts to access your bank account or launder fake checks written against legitimate businesses.
It’s a nasty and dangerous world out there. Think carefully. Ask questions. Seek a second opinion. Always remember this wise rule: “If it’s too good to be true, it probably isn’t.” And remember, the widow of Nigeria’s former defense minister does not want you to keep $34 million safe for her in your bank account. Really.
Summary
You are responsible for digital interactions and operations taking place using your accounts or on accounts administrated by you. You should work to prevent harm from resulting from any of that activity.
Understanding how criminals—and careless administrators—can put your data at risk is critical to learning how to protect yourself and the users you’re responsible for.
Before engaging in online activity, always try to think through the possible short- and long-term consequences. Is what you’re about to do likely to cause you or others harm?
Reading the privacy policy documents associated with the platforms and services you use can help you understand the threat environment you’ll be using.
Always examine the context of online information: is it part of a reliable website or associated with a well-known institution?
Be aware of the kinds of threats you’re likely to face as you go about your life on the internet. Only by understanding what can go wrong can you hope to protect yourself and the people who rely on you.
Back to the Basics
Understand common online attack behaviors, including cyberstalking, cybermobbing, and doxxing. Cyberstalking involves persistently pursuing an individual’s online and private identity in a threatening way. Cybermobbing is the cooperation of the owners of large numbers of online social media accounts to harass an individual with whom they don’t agree. Doxxers research and then publicize private information about an individual they want to harm.
Understand the kinds of personal data that are the most sensitive and vulnerable to abuse. Your browser history, social media account activities, online ecommerce transaction information, and health records are all categories of personal data that require special attention and protection.
Understand the regulatory requirements for which you and your infrastructure are responsible. Businesses operating in the European Union must conform to the policies of the General Data Protection Regulation (GDPR). The Payment Card Industry Data Security Standards (PCI-DSS), and the US government’s Health Insurance Portability and Accountability Act (HIPAA) are also important standards.
Be familiar with common kinds of digital “social engineering” attacks. Spam describes unsolicited email messages sent with the goal of getting you to respond, usually by purchasing a product of doubtful value. Spoofing misrepresents the origin and sender of the email. Phishing attacks try to get you to interact with a web resource that’s made to look like an actual legitimate site.
