10 Best Practices for Securing Personal Data Online

This article outlines 10 best practices for securing your personal data in 2024 when you’re online and using internet-connected devices. Following these simple guidelines can greatly reduce your risk of becoming the victim of cybercrime or data breaches.

In today’s digital age, we conduct more of our daily lives online than ever before. From shopping and banking to social media and email, much of our personal data exists on the internet. While the convenience of online services is undeniable, it also comes with risks related to data security and privacy. As cyber threats become more sophisticated, it’s crucial that individuals take steps to protect their personal data online.

Use Strong Passwords

One of the most basic but critical steps for securing online accounts is using strong passwords. Avoid common and easy-to-guess passwords like “123456” or “password.” Instead, create passwords that are at least 12 characters long and use a combination of upper and lowercase letters, numbers, and symbols.

Consider using a password manager app to generate and store unique passwords for each of your accounts. This ensures you’re not reusing the same passwords across multiple sites. Enable two-factor authentication whenever possible as an additional layer of security beyond your password.

Keep Software Updated

Outdated software and operating systems contain vulnerabilities that hackers can exploit to access devices and steal data. Set your computers, smartphones, apps, and internet-connected devices to automatically update whenever new software patches and firmware versions are released.

Updates often address critical security issues in addition to providing new features. Enabling automatic updates makes the process convenient and hassle-free.

Use Secure Websites

When shopping, banking, or accessing any site that requires entering your login credentials or sensitive information, ensure the site uses HTTPS rather than regular HTTP. HTTPS sites encrypt all data transmitted between your device and their servers to prevent theft.

Look for the padlock icon next to the URL and “https://” at the start of the web address. Avoid entering personal details on sites using unsecured HTTP connections.

Think Before Sharing

Be thoughtful about what personal details you share online. This includes things like your full name, address, birthday, phone number, current location, plans and schedule. Such information can aid cybercriminals in gaining access to your accounts or facilitate identity theft.

Adjust your privacy settings on social media sites to limit what data is visible to the public. Be wary of oversharing personal details on public platforms, in forums or with strangers online.

Install Security Software

Protect all your internet-connected PCs and devices by installing reputable security software, such as antivirus, anti-malware and firewall programs. Enable features like automatic scanning and real-time threat detection.

Security suites can identify malware, suspicious network activity, and known malicious sites that may attempt to infiltrate your device and steal data. Keep the software updated to protect against new threats.

Avoid Public Wi-Fi

Public Wi-Fi networks at coffee shops, hotels, airports and other locations are notoriously easy for cybercriminals to hack. Avoid accessing any sites containing personal data or making purchases when connected to public Wi-Fi.

If you must use a public network, leverage a virtual private network (VPN) to encrypt your internet traffic and online activities. Free and paid VPN services are available to secure your connection.

Back Up Your Data

Unexpected hardware failures, theft and device loss can jeopardize your personal files and data. Protect yourself by regularly backing up important documents, photos, emails and other irreplaceable data.

Use secure cloud storage services or external hard drives to create backups that are disconnected from your main devices when not actively backing up. Backing up makes recovering from data loss events easier.

Beware of Phishing Scams

Cybercriminals are constantly trying to trick victims into providing login credentials and personal information via convincing phishing emails, texts, calls and malicious websites. Hover over questionable links to preview destinations before clicking.

Be suspicious of any unsolicited communications asking you to update or verify account details. Instead, directly open the legitimate website yourself and login to view any notifications.

Manage Your Online Presence

Your online presence encompasses all mentions, photos and details about you on the internet. Perform periodic searches for your name online to identify any accounts or profiles using your personal information.

Request removal of any unauthorized usage to protect yourself from scams. Be cautious when posting details publicly online that criminals could leverage in social engineering and phishing scams targeting you.

Safeguard Your Data from Loss

Accidental data loss can be just as damaging as external data theft. Store important data in at least two separate locations, whether on the cloud, external storage or multiple devices. This creates redundancies if one location happens to fail, become corrupted or lost.

Encryption and password protection add additional security to guard your backups from unauthorized access if they fall into the wrong hands. Being diligent about backing up data minimizes downtime if data recovery becomes necessary.

Appropriate Usage of Online Services and Accounts

When signing up for online services and accounts, only provide the minimum amount of personal information required. Avoid giving unnecessary details that could expose you to risk.

Read all privacy policies, terms of service and opt-out of any data sharing where possible. Only enable permissions required for app functionality – disable unnecessary access to contacts, photos, location and microphone/camera by default.

Regularly check all connected apps and services linked to accounts for suspicious activity. Remove any unfamiliar linked apps, extensions or permitted API access.

Monitor Financial Accounts

Routinely check bank, investment, retirement and other financial accounts for any fraudulent activity indicating identity theft or unauthorized access. Report discrepancies immediately to mitigate losses from criminal activity.

Review monthly statements closely and set up text/email alerts for account changes or unusual transactions so issues can be caught early. Consider freezing credit reports when not actively seeking loans to block criminals from opening fraudulent accounts.

Beware of Risky Connected Devices

While smart home assistants, security cameras and other Internet of Things (IoT) devices offer convenience, they also provide potential entry points for hackers. Isolate IoT devices on their own protected networks instead of the one used by your personal devices.

Change device default credentials to unique passwords and enable two-factor authentication if available. Limit permissions and access from IoT vendors. Routinely check connected apps and linked accounts.

Securing Personal Data on Mobile Devices

On smartphones, limit app permissions so only essential apps have access to contacts, messages, camera, microphone, location and storage. Delete unused apps which may maintain access to your data.

Enable full-disk encryption on mobile devices to protect all data if the device is lost or stolen. Set screen lock passwords/passcodes to prevent unauthorized access – use biometric logins like fingerprint/face recognition for convenience. Keep mobile OS and apps updated.

Avoid saving passwords or financial details directly on mobile devices. Only download apps from trusted sources like official app stores. Install reputable mobile security apps to protect against malware/spyware threats designed to steal phone data.

Use Caution on Social Media

Exercise caution when sharing personal details like phone numbers, addresses, birthdays, and location/travel plans publicly on social media. Restrict visibility using privacy settings and limit connections to people you know.

Be wary of social media quizzes, games and apps requesting extensive personal details and account permissions. Ignore friend requests from suspicious profiles attempting to scam or phish for information. Report impersonator accounts pretending to be you or a known contact.

Maintain Physical Security

Don’t overlook physical safeguards for devices containing personal data like laptops, hard drives and smartphones. Store devices securely when not in use and enable tracking in case of loss or theft. Require PINs or passwords to boot devices.

Destroy sensitive paper documents using shredders when disposing. Keep sensitive items like passports, IDs and backup drives safely secured in private spaces to prevent unauthorized access by visitors or burglars. Restrict access to devices and secure areas to only trusted individuals.

Being proactive about securing personal data is essential in the digital age to minimize cybercrime risk. Follow this comprehensive guide of tips to keep your information safe in 2024 and beyond.
