Your web browser is your window to the digital world.  Whether it’s entertainment and news, or the ability to connect with friends and go shopping, the internet offers great experiences and a wealth of information. It’s hard to imagine our lives before the internet.

As in real life, when you’re online it’s important to be aware of your surroundings and ensure you trust those that you interact closely with.

Protect your device

Keep your operating system, security software, web browser and add-ons up-to-date by ensuring automatic updates are enabled or installed as soon as they are available. This dramatically reduces your device's exposure to malware. Be sure to read reviews of security software (such as anti-virus) to assess its reputation before you download them.

Is your browser session secure?

Before making a transaction or entering personal information on a web site, check that your browser address window is green, the URL (web address) has changed from 'http' to 'https' and that a closed padlock icon is present. Find out more about browsers that support this feature.

Go directly there

The safest way to access any web site is to type its web address directly into the browser and bookmark it. Hover over web links with your cursor to check for spelling errors or unexpected web addresses before you click. Phishing emails often contain links to dangerous sites. Learn more about email security and phishing.

Cyber security - email

Create strong, unique passwords

Choose passwords for your online services that are difficult for anyone else to guess. A strong password is long and complex (a variety of letters, numbers and other characters), unique (not re-used for other apps), current (changed at least every 90 days) and not obvious (avoid dictionary words, dates, names etc). Learn about how to create stronger passwords.

Maintain your privacy

Take charge of what you reveal about yourself online. Think twice about handing over any personal details unless you are confident it is absolutely necessary.
