    Secure File Sharing 11 Best Practices To Keep Your Organisation Safe

    Sharing documents is easy in today’s digital workplace with the many file sharing software solutions available on the market, but secure file sharing is another matter. The fast pace of business dealings can sometimes pressure employees into foregoing security practices meant to safeguard their organisations against data theft.

    The best practices below serve to reinforce the steps employees and managers should take to ensure their file sharing efforts aren’t putting the organisation at risk.

    11 Best Practices For Secure Online File Sharing

    1. Make use of VPNs.

    Everyone can’t always be in the safety of the office walls, accessing files from your secure corporate network. That’s why Gabe Turner of Security Baron recommends implementing a virtual private network (VPN) for use in situations that require accessing public wi-fi, for example. “Public wi-fis leave you vulnerable to hackers who want to steal your data. A VPN shields your web traffic in a secure tunnel, making it much more difficult to be intercepted by bad actors.”

    2. Employ password managers.

    If you’re a small business using simple file sharing options, you may have shared login and access credentials. While not ideal for security purposes, it’s understandable from a budget perspective. A cost-effective method for making things a bit more secure is using a password manager. “This service lets you securely share passwords with other users, so if you keep a file in an encrypted vault, you can simply give the other user your password and they can download the file from there,” explains Turner.

    3. Use strong passwords.

    Whether you’re using a password manager or a solution that enables password protection on files, Turner recommends creating strong passwords. “Strong passwords make it more difficult for bad actors to gain access to your important data. Passwords should be at least eight characters long, and use a combination of letters, numbers, capitalisation, and special characters where possible.”

    4. Set expiration dates for files.

    For secure file sharing with clients, you may not want certain files to be available forever. In these cases, Turner says to set expiration dates for accessibility. “That way, once the availability window closes, the file can’t be accessed on their end. Plus, you won’t have hundreds of files just floating around.”

    5. Limit file access by group.

    Limit access to both file folders and individual files in a structured manner. Shayne Sherman at TechLoris says an easy way to do this is to limit by specific groups. For example, create groups based on departments (e.g., accounting, marketing) or job levels (e.g., manager, senior manager). “Not everyone needs to access every file to do their job, so limit access by what makes sense for each group.”

    He also suggests limiting the creation of folders, since that can result in unnecessary chaos as users make new folders ad-hoc, without considering how they fit into the overall file structure. “Limiting the files and folders users can create and access helps keep permissions and file structures easier to maintain and understand.”

    6. Audit access privileges regularly.

    Matthew Fox of Valiant Technology recommends making a habit of reviewing who has access to what resources. “Just because a group or individual has a need to access certain files or folders today doesn’t mean they’ll still have that need in six months. Verify whether their access should continue as is, change, or be cut off entirely.”

    How frequently you audit access privileges depends on the level of rigor you want in your security measures. The more rigor, the more frequently you should audit.

    7. Employ multi-factor authentication.

    Regardless of who you’ve provided access to, your organisation should have multi-factor authentication (MFA) in place to ensure users are who they say they are. (Tweet this!) MFA uses two or more authorisation methods to verify a user’s identity:

    • Knowledge—something only the user knows, like a password or pin number.
    • Possession—something only the user possesses, such as a key fob or token, or a text (if the user has a mobile phone).
    • Inherence—something the user is, which typically involves a biometric identifier like facial or voice recognition.

    Stefan Chekanov of Brosix says to try striking a balance between a strong authentication security level and one that’s not overly burdensome. “You don’t want to create too many barriers for your users.”

    8. Educate and train staff on using your secure file sharing solution.

    Whatever secure cloud sharing solution you choose will likely have a learning curve for users. It’s essential you provide them with appropriate training to ensure they adopt the solution as part of their workflow. Otherwise, you risk users looking for workarounds.

    “File sharing software is used only when it’s understood and provides real value to users,” explains Fox. “If a solution doesn’t fulfill at least one of these criteria, you’re inviting shadow IT into your organisation by frustrated users, which can unwittingly circumvent many of your security measures.”

    9. Use end-to-end encryption when transferring data.

    For secure file sharing, Chekanov recommends peer-to-peer methods with end-to-end encryption. “In other words, aim for direct file transfers between two users that are encrypted on the sending end and decrypted on the receiving end. This keeps data safe while in transit by protecting it from any manipulation or unauthorised access.”

    He also notes that the encryption algorithm is crucial in this process. Use a strong encryption specification such as the Advanced Encryption Standard (AES), which is a global standard for keeping online communications safe. Notably, AES is employed by the U.S. government to protect classified information.

    10. Ensure your file sharing software fits into your overall security strategy.

    “When considering secure file sharing solutions, it’s easy to get overwhelmed,” says Chekanov. Not surprising given the tons of options on the market that vary in their features and functionality. But secure file transfer is only one element of a wider corporate security structure.

    Ideally, your file sharing software is part of a larger, integrated, and secure system. If not, then the high standards present in this one solution may be absent in, say, your email communication. “This can leave your organisation vulnerable despite your best efforts. Using an integrated system also makes things more easily manageable for your users, reducing the likelihood of security breaches due to human error.”

    11. Be aware of how your solution provider handles your data.

    The best secure file sharing services do more than tout bells and whistles on their product. They ensure your data is properly handled on the backend so you don’t end up with lost or stolen documents.

    “Encryption is important, but so is knowing how your service provider manages your data,” explains Fox. “Where do they store your files? How are permissions set up? Who can grant access? Getting answers to these questions may be a pain, but they help ensure your data remains secure.”
