1. Managing Your Social Media Privacy
Social media platforms are a treasure trove of personal information for cybercriminals. It's crucial to manage your privacy settings and be mindful of what you share.
Reviewing Privacy Settings
Regularly audit your privacy settings: Each platform (Facebook, Instagram, Twitter, LinkedIn, etc.) has different privacy settings. Take the time to understand them and adjust them to your comfort level. Focus on limiting who can see your posts, profile information, and friend list.
Limit audience visibility: Set your posts to be visible only to friends or specific groups, rather than the public. This prevents strangers from accessing your personal information.
Control tagging: Configure settings to require your approval before you are tagged in photos or posts. This prevents others from sharing information about you without your consent.
Being Mindful of What You Share
Avoid oversharing: Think before you post. Avoid sharing sensitive information such as your address, phone number, travel plans, or financial details. Even seemingly innocuous details can be used to piece together a profile of you.
Be cautious about location sharing: Turn off location services or be selective about when you share your location. Sharing your location publicly can make you vulnerable to stalking or burglary.
Consider your digital footprint: Remember that everything you post online is permanent and can be easily shared or copied. Future employers or acquaintances may see your posts, so be mindful of your online reputation.
Common Mistakes to Avoid
Accepting friend requests from strangers: Be wary of accepting friend requests from people you don't know. They may be fake profiles created to gather information or spread malware.
Participating in quizzes and surveys: Many online quizzes and surveys ask for personal information that can be used for malicious purposes. Avoid participating in these or sharing them on your profile.
Using the same password across multiple platforms: This makes it easier for hackers to access multiple accounts if one password is compromised. Use a strong, unique password for each social media platform.
2. Securing Your Online Accounts
Your online accounts are gateways to your personal and financial information. Securing them is essential to protecting yourself from cybercrime.
Using Strong Passwords
Create complex passwords: Use a combination of upper and lowercase letters, numbers, and symbols. Aim for a password that is at least 12 characters long.
Avoid easily guessable passwords: Do not use your name, birthday, pet's name, or other easily accessible information in your password.
Use a password manager: A password manager can generate and store strong, unique passwords for all your accounts. This eliminates the need to remember multiple passwords and reduces the risk of using the same password across multiple sites.
Change passwords regularly: Update your passwords every few months, especially for sensitive accounts such as email and banking.
Enabling Two-Factor Authentication (2FA)
What is 2FA? Two-factor authentication adds an extra layer of security to your accounts by requiring a second form of verification in addition to your password. This could be a code sent to your phone, a fingerprint scan, or a security key.
Enable 2FA whenever possible: Most major online services offer 2FA. Enable it for your email, social media, banking, and other important accounts. This makes it much harder for hackers to access your accounts, even if they have your password.
Use an authenticator app: Consider using an authenticator app like Google Authenticator or Authy instead of SMS-based 2FA, as SMS codes can be intercepted.
Monitoring Account Activity
Regularly check your account activity: Review your account activity logs for any suspicious logins or transactions. Report any unauthorized activity immediately.
Set up alerts: Enable email or SMS alerts for suspicious activity, such as logins from unusual locations or devices.
Be wary of phishing emails: Phishing emails are designed to trick you into giving up your login credentials. Be suspicious of any email that asks you to verify your account information or click on a link. Always go directly to the website of the service in question to log in.
3. Protecting Your Financial Information
Financial information is a prime target for cybercriminals. Taking steps to protect your credit cards, bank accounts, and other financial information is crucial.
Being Cautious of Online Transactions
Use secure websites: When making online purchases, make sure the website is secure. Look for "https://" in the address bar and a padlock icon. This indicates that the website is using encryption to protect your data.
Use strong passwords for financial accounts: As mentioned earlier, use strong, unique passwords for your online banking and credit card accounts.
Be wary of suspicious emails and links: Do not click on links in emails that ask you to verify your financial information. Go directly to the website of your bank or credit card company to log in.
Consider using a virtual credit card: Many credit card companies offer virtual credit card numbers, which are temporary numbers that can be used for online purchases. This protects your actual credit card number from being compromised.
Monitoring Your Accounts Regularly
Check your bank and credit card statements regularly: Look for any unauthorized transactions or suspicious activity. Report any discrepancies to your bank or credit card company immediately.
Sign up for transaction alerts: Many banks and credit card companies offer transaction alerts that notify you of any purchases made on your account. This can help you detect fraudulent activity quickly.
Be cautious of unsolicited offers: Be wary of unsolicited offers for loans, credit cards, or other financial products. These may be scams designed to steal your personal information.
Using Secure Payment Methods
Consider using PayPal or other secure payment platforms: These platforms act as intermediaries between you and the merchant, protecting your credit card information.
Avoid using public Wi-Fi for financial transactions: Public Wi-Fi networks are often unsecured, making it easier for hackers to intercept your data. Use a secure, private network when making online purchases or accessing your financial accounts. You can also explore our services for help with securing your network.
4. Avoiding Identity Theft
Identity theft occurs when someone steals your personal information and uses it to commit fraud. Taking steps to protect your identity is crucial to preventing this crime.
Protecting Your Personal Documents
Shred sensitive documents: Shred any documents that contain your personal information, such as bank statements, credit card bills, and medical records.
Store important documents securely: Keep your passport, driver's licence, and other important documents in a safe place.
Be careful about sharing your Social Security number: Only provide your Social Security number when absolutely necessary and to trusted sources.
Monitoring Your Credit Report
Check your credit report regularly: Obtain a free copy of your credit report from each of the three major credit bureaus (Equifax, Experian, and TransUnion) at least once a year. Look for any errors or suspicious activity.
Consider placing a fraud alert on your credit report: A fraud alert notifies creditors to take extra steps to verify your identity before opening new accounts in your name.
Consider a credit freeze: A credit freeze prevents anyone from accessing your credit report, making it more difficult for identity thieves to open new accounts in your name.
Being Aware of Phishing and Scams
Be wary of unsolicited emails, phone calls, and text messages: Do not provide personal information to anyone who contacts you unexpectedly.
Be suspicious of offers that seem too good to be true: Scammers often use enticing offers to lure victims into giving up their personal information.
Report suspected identity theft: If you believe you have been a victim of identity theft, report it to the police and the Australian Cyber Security Centre.
5. Using Secure Browsing Practices
Your web browser is your gateway to the internet. Using secure browsing practices can help protect you from online threats.
Keeping Your Software Up to Date
Update your operating system, browser, and antivirus software regularly: Software updates often include security patches that fix vulnerabilities that hackers can exploit.
Enable automatic updates: Configure your software to update automatically so you don't have to worry about manually installing updates.
Using a VPN on Public Wi-Fi
What is a VPN? A Virtual Private Network (VPN) encrypts your internet traffic and routes it through a secure server, protecting your data from being intercepted by hackers on public Wi-Fi networks.
Use a VPN when connecting to public Wi-Fi: This is especially important when accessing sensitive information such as your bank account or email.
Being Careful About Downloads and Links
Only download software from trusted sources: Avoid downloading software from unknown or untrusted websites. These downloads may contain malware.
- Be wary of clicking on links in emails and on social media: Phishing links can lead to malicious websites that steal your personal information. Always hover over a link to see where it leads before clicking on it.
