Cyber security made simple
Cyber security is something we all need to be aware of. In the past, it was focused on anti-virus software to stop pesky viruses from infecting your computer, but as we live more of our lives online and on our mobiles, it’s become a more complex topic to deal with.
Luckily, complex doesn’t have to mean difficult. We’ll help you understand the current cyber space a bit better by explaining a few common terms, how they could affect you and how you can improve your online safety.
What's the difference between cyber security and cyber safety?
While both aim to keep you safe online, cyber security protects your technology and data, while cyber safety protects you and your loved ones from online harm.
Cyber security
- Cyber security is about protecting your data, devices and systems.
- It uses tools like anti-virus software, firewalls, password managers and two-step verification.
- Cyber security helps block threats like malicious websites, malware, phishing scams and identity theft and financial fraud.
Cyber safety
- Cyber safety focuses on protecting protecting yourself from online harm and inappropriate content or behaviour.
- This includes risks like cyber bullying, image-based abuse and illegal or restricted online content.
- Tools like parental controls or family filters can limit exposure for children.
- It is important to report harmful content or behaviour to official bodies like the eSafety Commissioner.
What are some common cyber threats?
Cyber threats are anything that put your personal info or online safety at risk. Here are some of the most common threats.
Phishing
Scam emails, calls or messages that try to persuade you into sharing personal details like passwords or bank info. They often look like they’re from a trusted brand and may include links to malicious websites or attachments that could harm your computer.
Malware
This is a general term for malicious software that hackers use to get unauthorised access to your computer and steal personal information. It’s often hidden in suspicious downloads, ads, popups or phishing emails and messages. Viruses and ransomware are common types of malware.
Identity theft
When any unauthorised person has access to your personal information, they can use it to impersonate you. They can create fake identity documents and take out loans or make expensive purchases under your name. It can happen through hacking or even by someone you know who has access to your accounts.
Hacking and data breaches
Criminals can exploit vulnerabilities in apps or websites to steal large amounts of private data. While you can’t always stop a data breach, you can protect yourself by:
- keeping your devices and apps updated
- enabling two-step verification on your accounts.
How to protect yourself online
- Be cautious of any unexpected incoming communication, no matter if it appears to be from a company you use and trust, and regardless of whether it is an email, text message, or phone call. If in doubt, double-check by reaching out to a company using contact details from their official website.
- Use strong passwords. Consider making your passwords a phrase that is unique to you. Use a password manager to generate passwords and help keep them secure. Many security software packages, like Telstra Device Security, include a password manager.
- Enable multi-factor authentication whenever it is available. It's an extra level of security that needs multiple pieces of proof to log you in. To help keep your Telstra account secure, you can enable two-step verification, which is a type of multi-factor authentication.
- Keep your devices and apps updated. Make sure the latest iOS, MacOS, Android or Windows updates are applied. Most modern devices and apps will automatically check for updates and apply them.
- Add an extra protection with Telstra Device Security to your devices for stronger protection against scams, hackers and online viruses. Telstra Device Security helps keep your personal info off the dark web, secures your Wi-Fi and includes award-wining antivirus. It also protects against phishing, malware and other cyber attacks.
- Limit what you share online. Set your social media accounts to private and limit the amount of personal information you share online like your birthday, address or photos that identify your children’s school.
- Backup your data to the cloud or external hard drive regularly. This can protect you from data loss related to hardware failures, theft or malware.
- Use secure Wi-Fi. Be careful about sending and receiving confidential information over public Wi-Fi networks - it's easier for hackers to intercept it. You can turn any public hotspot into secure Wi-Fi with Telstra Device Security
What to do if you're affected by a cyber attack
When things go wrong, follow these tips to recover and get help:

- Recover your identity - If you think you’ve been the victim of identity theft, act quickly. For advice, contact IDCARE and use their free learning resources to help you work out what to do.

Keep kids safe online
Kids are more connected than ever - with access to devices, apps and games that parents can struggle to keep up with.
Restricting time spent online is a good start but becomes more difficult when kids need to be connected for school and for socialising during periods of isolation or lockdown.
Kids are also more vulnerable to the dangers of being on online - it's important to keep communication open, set up parental controls and make sure that kids understand the basics of cyber safety.
