Ferdousi, a homemaker from Chandpur, spends her evenings using imo, a messaging app that helps her stay connected with family members in another village. With limited knowledge of technology, she uses imo mainly for calls and messages. However, like many, she is unaware of the potential cybersecurity risks she faces.
Ferdousi is part of a growing number of people who, despite their active online presence, remain largely unaware of the threats in cyberspace. While increased internet access is beneficial, it also exposes users to scams, fraud, and harassment, especially for those with limited digital literacy.
To protect users like Ferdousi, raising awareness of cybersecurity basics is essential. Below is a simple guide to help everyone navigate the online world safely and avoid common cyber threats.
Account security is essential
The first step in protecting your digital presence is securing your accounts. Strong passwords are crucial. Avoid using easy-to-guess passwords like "123456" or your birthday. Instead, create unique passwords that mix letters, numbers, and special characters. Additionally, avoid reusing the same password across multiple accounts.
For added protection, enable two-factor authentication (2FA) wherever possible. This feature sends a verification code to your phone or email when logging in, making it much harder for hackers to access your account. Many apps, including imo, allow users to add biometric security, such as fingerprints or facial recognition, for even stronger protection.
One critical rule is: never share your One-Time Password (OTP) with anyone. OTPs are used for account verification, and sharing them can compromise your security. This simple rule can prevent unauthorized access to your accounts.
Be careful with personal information
Phishing scams are one of the most common ways cybercriminals deceive users. These scams often arrive via unsolicited messages that contain dangerous links. Clicking on these links can expose your personal information or install malware on your device.
Be cautious with messages that promise jobs, financial rewards, or urgent requests for personal information. Scammers often make their messages look like they come from trusted sources. Always verify the sender's identity before clicking on links or providing any personal details.
It's also important to protect your sensitive information. Never share details like your home address, passwords, or financial information in unprotected chats. If sharing is necessary, use encrypted platforms or activate privacy mode to ensure your conversations remain secure.
Protect your call and chat privacy
Instant messaging platforms are continuously enhancing their privacy features to protect users. Apps like imo offer security tools such as Privacy Chat, where messages are encrypted to prevent unauthorized access.
Take some time to explore the privacy settings of the apps you use. Activating features like Privacy Mode and regularly checking security settings can help safeguard your personal conversations. On imo, for example, you can enable Privacy Mode to protect both calls and messages, ensuring that your private communications remain secure.
Regularly update your apps
Keeping your apps up to date is another key element of cybersecurity. Developers often release updates that fix security vulnerabilities and protect against new threats. Failing to update your apps can leave your device exposed to cyberattacks.
Make it a habit to regularly check for app updates, particularly for apps handling sensitive information. Updated apps offer the latest security features, helping protect your personal data from cybercriminals.
Stay vigilant against scams
Even with robust security measures, staying alert is crucial. Scammers are becoming more sophisticated in their attempts to trick users into revealing personal information or sending money. One common method is social engineering, where scammers create a sense of urgency or fear to manipulate victims.
If you receive a suspicious message or call, don't rush to respond. Take time to verify the sender's identity, especially if they're asking for money or personal information. If the message appears to be from someone you know, contact them through another method to confirm its legitimacy.
Additionally, be cautious when interacting with unknown contacts. Many messaging apps allow users to verify new contacts before engaging with them. If you receive messages or calls from unfamiliar numbers, take steps to ensure they are not scammers.
Monitor logged-in accounts
Many apps, including messaging platforms, allow users to check which devices are logged into their accounts. Regularly monitoring this information helps spot unauthorized access. If you notice any unfamiliar devices, log them out immediately and change your password.
Enabling notifications for new logins can further protect your account. This feature alerts you when someone tries to log in from an unrecognized device, allowing you to take immediate action.
Avoid public wi-fi for sensitive transactions
Public Wi-Fi networks can be convenient but are often insecure, making it easier for hackers to intercept your data. Avoid using public Wi-Fi for sensitive activities like online banking or shopping. If necessary, use a Virtual Private Network (VPN) to encrypt your connection and protect your personal information from prying eyes.
Backup your data regularly
Backing up your data is a simple yet effective way to protect against cyber threats, including ransomware attacks. Regular backups ensure that you don't lose important information in case of an attack or hardware failure. Store backups on an external device or a secure cloud service to keep your data safe.
Cybersecurity is a shared responsibility
In today's digital age, protecting your online presence is not just a matter of convenience-it is essential for your safety. While the internet offers numerous benefits, it also comes with risks, particularly for those who lack cybersecurity knowledge.
By following these simple steps-securing your accounts, protecting personal information, staying vigilant against scams, and regularly updating your apps-you can significantly reduce the chances of falling victim to cyberattacks. Whether you're a homemaker like Ferdousi, a student, or a professional, everyone deserves to navigate the digital world confidently and securely.
With just a few precautions, you can protect your personal information and enjoy a safer, more secure online experience. Remember, cybersecurity isn't just for tech experts-it's for everyone.
