When We Talk About Safety, We Should Think What Kind of Things or Data We Are Thinking Safety Around. Are Free Cloud Storage Services Safe? In General, No. Free Cloud Storage Services Likely To Be Vulnerable From Various Points. Is Not it Expected That Personnel Looking After Will Be Lesser?
Are Free Cloud Storage Services Safe?
No public cloud storage which has username and password to login is safe for the basic chance of higher success of brute force attempts. Normally we tend to use memorable username and password which gives a good chance of guess by attacker. It is not really about paid or free.
As like we stated at the beginning, free cloud storage services likely to have lesser personnel to manually keep a continuous vigorous surveillance. Of course, anyone can create an account with any identity increases the vulnerability. It is not exactly easy to have money transaction methods like credit cards, PayPal with false identity. Those services either nullify or prohibits usage of fake names. The payment system itself acts as a security gateway.
Additionally, being exposed to public internet, the services naturally faces zillions of targeted attacks. Although, very few compared to number of providers still date has been reported to be knocked down with mass compromise, with increasing number of hacking attempts, it is not unusual to get a free account compromised.
How We Can Securely Use Free Cloud Storage Services?
We can increase basic security by not using free cloud storage services for too sensitive data. Secondly, we should use difficult to guess passwords with commonly used email accounts. It is more dangerous if any automatic notification of the service provider fails due to using a less used email account. Third, we should keep out files in a directory with password encryption and then upload it to free could storage services.
There are many practical matters, more than technical matters which can increase your spectrum of risk. For example, if we have a photograph with exposing personal details or a file with passwords of other accounts, they may become our point of breech of security.
Free cloud storage services essentially are intended for not much sensitive data usually with longer legal disclaimer of their weak points.
It is obvious that, provider to provider there will be difference in many points which may vary the level of real security than perceived.
