Make IT secure: everyday security habits

Most successful attacks do not depend on clever hacking. They rely on a reused password, a device that was never updated or an email that looked genuine. The habits below close those common gaps, whether you work from home or in a small office.

Protecting yourself

  • Use a different, strong password for every account. A password manager can create and remember them for you.
  • Turn on two-factor authentication (2FA) wherever it is offered. It asks for a second proof of identity, such as a code on your phone.
  • Think before sharing personal details online. Do not click links or open attachments from senders you do not recognize.
  • Install security updates on your computer, phone and other devices as soon as they are available.
  • Protect sensitive data with encryption. Look for HTTPS (the padlock in the address bar) when browsing, and encrypt stored files that matter.

Securing your Wi-Fi and router

  • Protect your Wi-Fi with a strong password and turn on encryption. WPA3 is best, and WPA2 is acceptable if your devices do not support WPA3.
  • Update your router’s firmware, its built-in software, on a regular basis.
  • Switch off remote management on the router unless you need it, and replace the default login with your own strong credentials.
  • Avoid public Wi-Fi for sensitive tasks such as online banking.

Handling information carefully

  • Share financial or personal data only with people and organizations you have verified.
  • Check the privacy settings on your social media accounts now and then, and limit what is public.
  • Watch for phishing, which means messages that pretend to come from a trusted source to trick you into handing over passwords or personal details. If a request seems unusual, confirm it through a separate channel before you act.

None of this is complicated, but it only works when it becomes routine. Revisit these habits every few months, because attackers keep changing their tricks.
