6 Critical Cloud Storage Security Concerns: What I Don’t Backup to the Cloud

Cloud storage offers incredible convenience, allowing users to access their files from virtually anywhere and enabling seamless collaboration. Nonetheless, this ease of access comes with potential security vulnerabilities. Storing sensitive or important files in cloud environments can expose them to various cyber threats. Consequently, there are several types of data you should steer clear from backing up to the cloud.

1. Financial Documents

Keeping sensitive financial information, such as bank details, credit card numbers, tax returns, and loan agreements, in the cloud presents significant risks. If cybercriminals gain unauthorized access to your cloud account, they can exploit your financial data for fraudulent activities. This could result in unauthorized withdrawals or loans taken out in your name, leading to devastating financial repercussions and potential damage to your credit score.

Even without immediate financial loss, the fallout from a data breach can be exhausting and stressful. You may have to deal with banks, credit card companies, and other financial entities to safeguard your accounts and mitigate further damages, which can include freezing accounts and blocking credit cards.

It is advisable to refrain from storing any type of financial documentation in the cloud.

2. Private Media Files

Many individuals enjoy preserving their cherished private moments. However, when it comes to storing explicit or sensitive media in the cloud, caution is crucial. If your cloud storage becomes compromised, the ramifications could be severe.

Hackers may leak your private media online, leading to threats of sextortion where the perpetrators might demand money or favors in exchange for not releasing your sensitive content. The infamous 2014 iCloud breach, where explicit photos of celebrities were stolen and shared, underscores the serious risks associated with this practice. Therefore, it is best to keep such personal media off cloud storage platforms.

3. Intellectual Property (IP) and Business Data

Organizations possess unique intangible assets known as intellectual property (IP), which are legally protected and can be bought, sold, or licensed.

Types of intellectual property include:

• Copyrights: Protects original creations like books, music, films, and software.
• Patents: Provides exclusive rights to inventors for their inventions.
• Trademarks: Safeguards distinctive signs identifying products or services, including brand names and logos.
• Trade Secrets: Confidential information offering a competitive edge, such as business formulas, recipes, or client lists.

A single breach can jeopardize not only your business data but also expose valuable information such as customer lists, enabling competitors to capitalize on your proprietary information and potentially diminishing your market share and revenue. In addition to financial fallout, businesses might encounter reputational damage that can erode customer trust.

Legal disputes to recover misappropriated IP can be lengthy and costly, making it wise to avoid placing your company’s sensitive information and intellectual property in cloud storage for the sake of security.

4. Passwords

Passwords play a vital role in securing our digital identity, shielding our personal information, financial accounts, and online profiles. Unfortunately, many users store their passwords in plain text files, and worse, on the cloud.

Once your cloud account is breached, all your digital credentials could be jeopardized.

A more secure method is to utilize a password manager to avoid keeping passwords in a text file. With a password manager, you only need to remember one robust master password. It will generate unique, strong passwords for each of your online accounts and alert you to any compromised credentials, thereby enhancing your security and mitigating identity theft risks.

5. Legal Documents

Legal documents like court orders, judgments, and attorney communications are often highly confidential. They carry a heightened risk of unauthorized access or exploitation.

Storing important legal documents in the cloud can expose sensitive information including contracts and confidential client communications, which may result in severe legal and financial ramifications.

6. Personal Identification Proofs

Documents issued by the government, such as passports, driver’s licenses, national IDs, and social security cards, contain highly sensitive personal data that necessitates strict protection. Storing these documents in the cloud could lead to unauthorized access.

If your cloud account is compromised, hackers could steal your personal data for identity theft, phishing, or social engineering scams. They might exploit your identification to apply for loans or obtain SIM cards for illicit activities.

Moreover, cybercriminals may use your stolen identity info to easily reset your online credentials, granting them access to sensitive data throughout the internet.

Preventing Cloud Storage Security Concerns

Consider adopting these strategies to enhance the protection of your cloud storage:

• Employ Strong, Unique Passwords and Update Regularly: Use complex passwords, mixing uppercase and lowercase letters, numbers, and symbols. Avoid easily decipherable details like birthdays or pet names, and enable two-factor authentication (2FA) for extra protection.
• Encrypt Your Data: If feasible, encrypt sensitive files before uploading them to the cloud.
• Implement Access Controls: Set up appropriate access controls to regulate who can view, modify, or delete your files, assigning permissions based on roles.
• Regular Backups: Have routine backups of your files saved to external or local storage devices to safeguard against data loss.
• Select Reputable Vendors: Research and opt for cloud storage providers with a strong security reputation. Certifications like ISO 27001 and SOC 2 Type II are indicators of their commitment to security standards.
• Be Cautious When Sharing: Be selective about sharing files; avoid sharing sensitive information with untrusted individuals or organizations.
• Monitor Account Activity: Keep an eye on your cloud account for any suspicious activity, including unauthorized login attempts or abnormal file access.
