How to Stay Safe Online: A Complete Guide to Internet and Computer Security

Learn simple and practical ways to protect your computer, phone, online accounts, personal information and everyday internet activity.

Why Staying Safe Online Is Important

The internet makes it easy to communicate, shop, work, study, manage money and store important information. At the same time, online scams, malicious software, stolen passwords and other security problems can affect anyone.

The good news is that you do not need to be a cybersecurity expert to improve your online safety. Simple habits, used consistently, can help reduce many common risks.

Start With These Basic Security Habits

Use strong passwords, enable multi-factor authentication, keep your software updated, be careful with links and attachments, protect your personal information and maintain backups of important files.

Your password protects access to your online accounts. If the same weak password is used on several websites, one compromised account can potentially create problems elsewhere.

Multi-factor authentication, or MFA, adds an additional verification step when signing into an account.

If someone obtains your password, MFA can provide another layer of protection because access may require an additional verification method.

Phishing messages are designed to trick people into clicking links, opening files, sharing information or making payments. They can arrive through email, text messages, social media or other communication platforms.

If a message seems suspicious, do not rush. Verify the request through a trusted method before taking action.

Operating systems, browsers and applications receive updates for many reasons, including fixing security weaknesses.

Keep your important software updated and use automatic updates where appropriate. Regular updates can help protect devices against known security problems.

Only install applications and download files from sources you trust. Be particularly careful with unexpected attachments or software promoted through suspicious advertisements and pop-ups.

Think carefully before sharing information online. Personal details can sometimes be used for scams, identity theft or unwanted access to accounts.

Before providing sensitive information, ask who is requesting it, why they need it and whether the request is genuine.

Public Wi-Fi can be useful in cafés, airports, hotels and other locations. However, you should still be careful when using unfamiliar networks.

Avoid unnecessary sensitive activity on networks you do not trust, and make sure your device and applications are kept up to date.

Important files should not exist in only one place. A backup gives you another copy if your device is lost, damaged or affected by a security incident.

Phones, browsers, social networks and applications often include privacy and security controls. Take time to review what information an application can access.

Remove unnecessary permissions where appropriate and review important account settings regularly.

One of the most useful online security habits is simply slowing down. Many scams depend on people reacting quickly to fear, excitement or urgency.

How to Keep Your Computer Secure

Your computer contains valuable information, from documents and photographs to saved accounts and work files. Basic maintenance can improve its security.

Stay Safe on Social Media

Social media can reveal more information than you realise. Be thoughtful about what you post publicly and who can access your content.

• Review your privacy settings.
• Be careful when accepting unknown contacts.
• Do not share sensitive information publicly.
• Be cautious of unexpected messages and investment or giveaway scams.
• Secure your social accounts with strong passwords and MFA.

Email Security Basics

Email is a common way for scammers to contact people. An email can contain a misleading link, attachment or request designed to make you act quickly.

Online Safety for the Whole Family

Cybersecurity is easier when everyone in a household follows similar basic rules. Children, teenagers and adults can all benefit from learning how to recognise suspicious messages and protect personal information.

As technology continues to change, keep learning and review your security habits regularly. Small improvements can make your digital life safer and more secure.
