Dangerous for security – which documents should not be uploaded to the cloud / Marco Technologies
Cloud services are convenient for storing data, but not all files are worth uploading there. Some types of documents can pose a serious risk if leaked or hacked.
Cloud storage has long been a popular tool for backing up and accessing data from any device. However, even the most secure servers do not guarantee complete security, so it is better to leave certain categories of files only on local media. This is what BGR writes.
Which files are best kept locally only?
First of all, it concerns documents with personal data. These can be scans of passports, driver's licenses, birth certificates or other files that contain your full name, date of birth, address or document numbers. If leaked, such information greatly simplifies identity theft – attackers can apply for loans, open accounts or make purchases in your name.
Another risky category is financial documents . Bank statements, tax returns, bills, or investment reports contain critical information about your finances. If compromised, this data can be used to access accounts or commit fraudulent transactions. That is why it is recommended to store such files on local media, such as external hard drives.
According to Lock.pub , medical data also needs increased protection . While fitness trackers and apps already collect some information, full medical records are best trusted only to doctors or specialized secure systems. If leaked, such data can be used not only for fraud, but also to gain access to medical services or prescriptions on behalf of the patient.
Legal documents are worth mentioning separately . Wills, contracts, powers of attorney or property documents are extremely confidential. If they fall into the hands of third parties, this can lead to serious consequences – from blackmail to attempts at forgery or use in fraudulent schemes.
Experts recommend using the cloud for less sensitive files – photos, videos or work documents. Instead, personal and confidential information is better stored offline – on secure media or even in paper form.
