Enable multi-factor authentication (MFA)
Use multi-factor authentication (MFA) that requires additional security measures, such as face authentication or OTPs, for access.
Review account activity regularly
Always check your account to ensure that no suspicious activities are being performed without your knowledge or awareness.
Avoid unnecessary file sharing
Never share personal files or links on online platforms or with any unfamiliar persons.
Limit permissions for connected apps
When prompted, carefully review app permissions before consenting; research first how data is processed by the app.
Keep devices updated
Regularly check for the latest updates on your devices’ operating systems or features to receive up-to-date protection and patches.
Applying these cloud data protection best practices can greatly help in reducing the risk of data exposure while also empowering users to be more responsible with their personal information.
How to encrypt personal data in cloud storage apps
Data encryption is one of the most powerful security tools users can employ to protect their cloud data. It works by transforming data into complex code that is only intelligible to certain parties. This ensures confidentiality and prevents unauthorized access from outsiders.
Encryption also protects data in different phases of its use, whether it remains unused and stored or in transit when sent from one user to another. For the latter, end-to-end encryption is utilized, where the sender encrypts the data to be decrypted only by the receiver, ensuring limited access.
Data encryption best practices
Users can leverage data encryption by following these best practices.
Choosing services with strong encryption
With multiple third-party vendors offering encryption services, it’s best to choose one that utilizes strong encryption protocols, possesses security certifications, and has proven reliability by clients.
Enabling encryption features where available
Likewise, users should also check the encryption software’s overall file and software compatibility, so its features can be easily enabled when needed.
Encrypting sensitive files before uploading
Sensitive files containing details (like personal information, financial data, and health status) are prime targets for data theft, so be sure to encrypt such files before adding them to the cloud.
Besides applying data privacy practices, using data encryption adds a strong layer of security that ensures that only you and a select few can open it.
Protecting personal information in online services
In this age of digitalization, sectors such as healthcare and finance are adopting online services (for example, mobile apps, online customer service) to reach out to customers more efficiently.
However, these, too, often require the use of personal information to function effectively, making organizations subject to compliance laws and regulations like the GDPR and the HIPAA.
These rules also empower users to exercise their data privacy rights by letting them determine how their personal data is used. Regardless, it is still essential for users to learn how to protect their personal data when shared or utilized in these online services.
Online services best practices
To reduce the risk of having personal data leaked or stolen on online platforms, it is best to follow these safe practices.
Limit personal information shared online
Never give out details that are not required to be shared with the organization. Avoid posting sensitive information on social media, especially if your account can be viewed publicly.
Review privacy settings regularly
Many applications enable users to configure their privacy settings to limit information that can be viewed publicly. Check how these settings are set, and change them when needed.
Avoid storing sensitive data in unsecured apps
Never assume that all applications will keep your personal data safe and secure. Always check if you can enable security features like passwords and two-factor authentication before storing data in the application.
Be cautious with links and attachments
Be wary of any links and attachments shared by unofficial or suspicious sources, and do not click them immediately when you see one. If possible, hover on the link to check if it leads to an organization’s official site.
Monitor accounts for suspicious activity
Perform regular checks on your accounts for any activity that may be done without your knowledge or presence. Monitor aspects like banking and download histories, and enable alert notifications if possible.
Following these best practices ensures that users can protect personal data while using online services and applications safely.
Safe usage habits for cloud services
As previously stated, not all cloud services offer the same security features or guarantee data protection. Therefore, it is still up to the user to ensure that their personal data is well-secured, even when stored in the cloud.
Here are daily habits you should adhere to when using cloud services to store data:
Log out of shared devices
When using a cloud application on a shared device like a public PC or work unit, do not forget to log out after use to prevent the next user from accessing your cloud data.
Avoid public WiFi without protection
As much as possible, do not open your cloud storage while your device is connected to a public WiFi, as external threats use this as a pathway to access a user’s device. However, if it is necessary, enable a VPN or any protective measure before opening the cloud.
Update passwords regularly
While using long and complex passwords is recommended, changing your password on a regular basis (for example, monthly) adds another layer of security that lessens the likelihood of unauthorized access.
Back up important data
Besides storing your data in a cloud service, it is also prudent to have additional copies in backups, like hard drives and other storage mediums.
Be cautious with unknown messages
Emails and texts of unknown origins should never be opened upon seeing them. Verify first if it comes from a legitimate source, or ignore it entirely.
Practicing safe use of cloud services helps reduce the long-term risks of data leakage and unwarranted access.
Common misconceptions about cloud data privacy
Many users of cloud services have several misunderstandings about how cloud data privacy works, leading to a false sense of security and consequently leaving their stored personal data vulnerable to exposure.
Misconception #1: Cloud services fully protect personal data
While cloud service providers are generally in charge of maintaining the functionality and integrity of the cloud infrastructure, the responsibility of securing the individual account and its associated data remains largely with the user.
