The first happened in when a compromised password was used to access a Dropbox account owned by an employee. At the time, Dropbox said the hack provided an intruder with access to documents containing a handful of customer email addresses, which became the target of phishing attacks.
This prompted Dropbox to add two-factor authentication to account logins. However, in it was revealed that the hack was much larger than previously thought, with a dumped database of 68 million passwords being leaked online that was said to stem from the initial breach. Dropbox said at the time that there were no indications that user accounts had been compromised following the incident. Apple has built up a reputation for excellent security. Although its iCloud platform had its reputation tarnished briefly when it fell victim to a high-profile hack in , the service continues that trend by offering users a robust set of security features.
The only exception to this is in the iCloud keychain, used to store and transmit passwords and other sensitive user data, which uses bit encryption. Like many other platforms, iCloud provides security tokens for added authentication when accessing other apps through it, as well as two-factor authentication at login. In , iCloud came under intense scrutiny after hackers breached around 50 accounts belonging to celebrities and leaked their contents online. Even now, the iCloud hack remains one of the most famous data leaks in history.
It generally uses the same standards as others, including data encryption, only with OneDrive this is done by syncing your data to the BitLocker on your hard drive. This means that data is encrypted at rest using the BitLocker, while Microsoft Cloud handles encryption while in transit. An additional bonus of this system is that encryption is done on a per-file basis, meaning that if a key was compromised hackers would only be able to access that particular file.
Microsoft has taken steps to remove as many of these issues as possible, and is one of a number of companies championing passwordless logins. The decision you have to make as a customer is deciding which storage platform does the most to avoid potential security incidents.
The factors that influence this decision will vary depending on the nature of your business and whether you have specialist requirements, such as businesses in a heavily regulated industry.
However, for most consumers and small businesses , each of the platforms listed here are generally good enough for protecting data, as each provides some form of data encryption at rest and in transit - which is perhaps the most important thing here. Data protection is also improving all the time, and each of these platforms are being updated with better safeguards each year, meaning you can typically rely on the company to do most of the legwork.
In response to this Dropbox security breach, the service made a public blog post and added some security upgrades. At this time, anyone with potentially compromised details received a prompt asking them to change their password. Options such as two-step verification became available, and the security tab also gained the ability to log out other devices.
However, there was no policy change here, and your files can still be decrypted and viewed at any time. After the Dropbox security breach, there were no known major problems until , when users saw deleted files reappear on their accounts. This means that some data from six years ago was never deleted and was vulnerable to a leak.
In order for Dropbox to interact with other apps, data needs to move freely between the two companies. If the files needed to first be decrypted by your device, the whole process would slow down. To get around this, Dropbox holds on to your encryption key so they can look at your files whenever they want.
However, other services use zero-knowledge encryption, where your password is a secret and no one else can access your files. Some U. However, as it stands, your files would be at less risk with a company based somewhere with stronger cloud privacy laws. If you want to protect your files, you could always move to another provider. How secure is Dropbox? Not secure enough for business!
Nor can they control who has access to shared files. Dropbox does not allow companies to view an audit log, so if sensitive data is leaked, admins have no way of knowing who may have accessed it. Business users collaborate on files differently than individuals. Business collaboration requires granular control over permissions to ensure appropriate access levels for dozens of collaborators and stakeholders. This protects against accidental overwrites or deletions, but it also preserves security and secrecy.
Your data is sitting on the same public cloud next to content from millions of other users, without adequate isolation.
