Cybersecurity may seem complex, but you don’t have to be an expert to protect yourself. In fact, the most effective security measures are often the simplest. By adopting a few essential habits, you can significantly reduce the chances of cybercriminals compromising your accounts, devices, or personal information.
Here are 10 assertive habits you should adopt to become a harder target:
1. Use complex, Unique Passwords
Using a different password for each account helps prevent a single data breach from putting multiple accounts at risk. When a website is breached, cybercriminals may try the stolen username and password on other platforms. If you reuse that password, those accounts could be vulnerable too. A password manager can help you create and securely store strong, unique passwords, so you don’t have to remember each one.
2. Turn On Multifactor Authentication (MFA)
Multifactor authentication (MFA) adds a verification step to your sign-in, helping protect your account even if someone steals your password. This might involve a code from an authenticator app or a physical security key. Enable MFA wherever it’s available, and choose an authenticator app, security key, or passkey when offered rather than relying solely on text messages. Never approve a sign-in request you didn’t initiate—it could mean someone else is trying to access your account.
3. Keep Your Devices Updated
Software updates can do more than add new features. They often fix security weaknesses that cybercriminals could use to access your devices or information. Keeping your operating system, browser, applications, and router up to date helps close these gaps. Install updates promptly to reduce the time your devices remain exposed to known vulnerabilities. Enable automatic updates where available, and check regularly for updates that need to be installed manually.
4. Stop and Think Before You Click
Phishing messages try to trick you into sharing sensitive information, clicking a harmful link, or opening a malicious attachment. They often create a sense of urgency to encourage you to act before checking whether the request is genuine.
Common examples include:
- “Your account will be disabled.”
- “Payment is required immediately.”
- “Review this document now.”
- “Your package could not be delivered.”
An urgent message is not always a scam, but it is a reason to pause. Before clicking a link or opening an attachment, consider whether you expected the message and whether the request makes sense. If you’re unsure, verify it through a phone number, website, or other contact method you already trust.
5. Protect Your Phone
Your smartphone holds personal information such as emails, photos, financial apps, and verification codes, making it important to protect both the device and the information it contains. Set a strong PIN or password, and enable fingerprint or facial recognition if available to help prevent unauthorized access. Keep your operating system and apps updated, and download apps only from trusted sources. Enable your phone’s built-in lost-device features from Apple or Google before you need them. These tools can help you locate, remotely lock, or erase a missing phone, depending on your device and settings.
6. Be Cautious About What You Share Online
Personal details you share publicly can help cybercriminals make scams more convincing. Information about your birthday, family members, pets, employer, or hobbies can give a phishing message a familiar touch, making it seem as though the sender knows you. Vacation plans and location updates can also reveal where you are or when you’re away from home. Before posting, consider what a stranger could learn and whether the information needs to be public. Review your privacy settings regularly to help control who can see your posts and profile details.
7. Secure Your Home Wi-Fi
Your router connects your devices to the internet, so securing it is an important part of protecting your home network. Use WPA3 encryption when available, or WPA2, to help protect information transmitted over Wi-Fi. Set a strong, unique Wi-Fi password and change the router’s default administrative password, which controls access to its settings. Check regularly for firmware updates and enable automatic updates if supported. If the manufacturer no longer provides security updates, replace the router with a supported model.
8. Be Suspicious of Unexpected Requests
Cybercriminals often impersonate people you trust. When you receive a message appearing to come from your boss, bank, coworker, family member, or a familiar company, scrutinize it. They may ask for money, passwords, verification codes, or sensitive information. If the request seems unusual or urgent, verify it independently.
9. Back Up Your Important Information
Security isn’t solely about prevention; it’s also about recovery. Ensure that your important files and photos are backed up. While cloud services can be part of your strategy, maintain an additional backup of particularly critical information. A backup is vital in the event of ransomware, hardware failures, theft, or accidental deletion.
10. Report Anything Suspicious Immediately
Trust your instincts; if something seems off, act on it. Report any suspicious email, login notification, MFA request, or website activity without delay. At work, inform your IT or Information Security team as soon as possible. Even if you’ve already interacted with something questionable, quick reporting enables security teams to mitigate potential harm.
Small Habits Make a Big Difference
Understand that no single tool can make you completely secure. Effective cybersecurity requires multiple layers of protection. Strong passwords, MFA, timely updates, backups, cautious clicking, and a healthy dose of skepticism are essential. You don’t need to be impossible to hack; you must simply make it as challenging as possible for attackers. Take action now!
