Smartphone Security Tips for Australian Users
In today's digital age, smartphones are an integral part of our lives. We use them for communication, banking, entertainment, and much more. However, this convenience comes with a responsibility to protect our devices and the sensitive data they hold from cyber threats. This guide provides practical advice specifically tailored for Australian users to enhance their smartphone security.
1. Setting Up Strong Passwords and Biometrics
The foundation of smartphone security lies in creating strong passwords and utilising biometric authentication methods. A weak password is like leaving your front door unlocked, making it easy for cybercriminals to access your personal information.
Creating Strong Passwords
Length Matters: Aim for passwords that are at least 12 characters long. The longer the password, the harder it is to crack.
Complexity is Key: Use a combination of uppercase and lowercase letters, numbers, and symbols. Avoid easily guessable information such as your name, birthday, or pet's name.
Unique Passwords for Each Account: Reusing passwords across multiple accounts is a major security risk. If one account is compromised, all accounts using the same password become vulnerable. Consider using a password manager to generate and store strong, unique passwords for each of your accounts.
Avoid Common Password Mistakes: Don't use common words or phrases, dictionary words, or sequential numbers (e.g., 123456). These are easily guessed by hackers.
Utilising Biometric Authentication
Fingerprint Scanning: Most modern smartphones offer fingerprint scanning as a convenient and secure way to unlock your device. Ensure your fingerprint is properly registered and consider registering multiple fingers for redundancy.
Facial Recognition: Facial recognition is another popular biometric authentication method. While convenient, it's important to be aware that facial recognition may not be as secure as fingerprint scanning, especially in low-light conditions. Some facial recognition systems can be fooled by photos or videos.
Combining Biometrics with Passwords/PINs: For added security, consider enabling the option to require a password or PIN after a certain number of failed biometric attempts. This prevents someone from repeatedly trying to unlock your device using your fingerprint or face.
2. Enabling Two-Factor Authentication
Two-factor authentication (2FA) adds an extra layer of security to your accounts by requiring a second form of verification in addition to your password. This makes it significantly harder for hackers to access your accounts, even if they manage to obtain your password.
How Two-Factor Authentication Works
When you enable 2FA, you'll typically be asked to provide a second verification method, such as:
SMS Codes: A code is sent to your phone via SMS, which you must enter to verify your identity. While convenient, SMS-based 2FA is vulnerable to SIM swapping attacks.
Authenticator Apps: Authenticator apps like Google Authenticator, Authy, or Microsoft Authenticator generate time-based one-time passwords (TOTP) that you can use to verify your identity. These apps are generally more secure than SMS codes.
Hardware Security Keys: Hardware security keys like YubiKey are physical devices that you can plug into your computer or phone to verify your identity. These are the most secure form of 2FA.
Enabling 2FA on Your Accounts
Most major online services, including Google, Facebook, Apple, and Microsoft, offer 2FA. To enable 2FA, typically you need to go to the security settings of your account and follow the instructions. It's highly recommended to enable 2FA on all of your important accounts, especially those containing sensitive information like banking details or personal data.
Backup Codes
When setting up 2FA, you'll usually be provided with backup codes. These codes can be used to regain access to your account if you lose access to your primary 2FA method (e.g., you lose your phone). Store these backup codes in a safe place, such as a password manager or a physical document stored securely.
3. Being Aware of Phishing Scams
Phishing scams are a common way for cybercriminals to trick people into revealing their personal information. Phishing attacks often involve emails, text messages, or phone calls that appear to be from legitimate organisations, such as banks, government agencies, or well-known companies. These messages typically try to lure you into clicking a malicious link or providing sensitive information.
Identifying Phishing Attempts
Suspicious Sender Addresses: Be wary of emails or text messages from unknown or suspicious sender addresses. Check the sender's email address carefully for misspellings or unusual domain names.
Urgent or Threatening Language: Phishing messages often use urgent or threatening language to pressure you into taking immediate action. For example, they may claim that your account will be suspended if you don't update your information immediately.
Requests for Personal Information: Legitimate organisations will rarely ask you to provide sensitive information like your password, credit card number, or bank account details via email or text message.
Grammatical Errors and Typos: Phishing messages often contain grammatical errors and typos. This is because they are often written by non-native English speakers.
Unsolicited Attachments or Links: Be cautious of opening attachments or clicking on links in unsolicited emails or text messages. These may contain malware or lead to phishing websites.
Protecting Yourself from Phishing
Think Before You Click: Always think carefully before clicking on links or opening attachments in emails or text messages.
Verify the Sender's Identity: If you're unsure about the legitimacy of a message, contact the organisation directly to verify its authenticity. Use a phone number or website that you find independently, rather than relying on the information provided in the message.
Report Phishing Attempts: Report phishing attempts to the Australian Competition and Consumer Commission (ACCC) via the Scamwatch website. This helps to protect others from falling victim to similar scams.

4. Keeping Your Software Updated
Software updates often include security patches that fix vulnerabilities that can be exploited by hackers. Keeping your smartphone's operating system and apps up to date is crucial for maintaining its security.
Updating Your Operating System
Enable Automatic Updates: Most smartphones allow you to enable automatic updates, which will automatically download and install updates when they become available. This is the easiest way to ensure that your device is always running the latest software.
Check for Updates Manually: If you don't have automatic updates enabled, you should regularly check for updates manually in your device's settings.
Updating Your Apps
Enable Automatic App Updates: Similar to operating system updates, you can enable automatic app updates in the Google Play Store (for Android devices) or the App Store (for iOS devices).
Review App Permissions: Regularly review the permissions that your apps have access to. If an app is requesting permissions that seem unnecessary or excessive, consider uninstalling it.

5. Using a VPN for Public Wi-Fi
Public Wi-Fi networks, such as those found in cafes, airports, and libraries, are often unsecured, making them vulnerable to eavesdropping. When you connect to a public Wi-Fi network, your data can be intercepted by hackers. Using a Virtual Private Network (VPN) encrypts your internet traffic, protecting your data from being intercepted.
How a VPN Works
A VPN creates a secure, encrypted connection between your device and a VPN server. All of your internet traffic is routed through this encrypted tunnel, making it unreadable to anyone who might be trying to eavesdrop on your connection.
Choosing a VPN Provider
Reputable Provider: Choose a reputable VPN provider with a strong track record of security and privacy. Read reviews and compare different providers before making a decision.
No-Logs Policy: Look for a VPN provider that has a strict no-logs policy, meaning that they don't track or store your browsing activity.
Server Locations: Choose a VPN provider with servers located in Australia or other countries that you frequently access. This will ensure that you get the best possible performance.
Encryption Strength: Ensure that the VPN provider uses strong encryption protocols, such as AES-256.
Using a VPN on Your Smartphone
Most VPN providers offer apps for both Android and iOS devices. Simply download the app, create an account, and connect to a VPN server. It's a good idea to enable the VPN whenever you're using a public Wi-Fi network. For any further questions, check out our frequently asked questions.
