Secure File Sharing Solutions vs Unsecure File Sharing Solutions

Transferring documents via the Internet is a regular operation, and protecting transferred materials is of paramount importance to the majority of common businesses. There several solutions to transfer documents and many methods to protect those documents in the course of the transfer process. In this article, we will look at the most popular secure and insecure ways to transfer data.

What Are the Secure File Sharing Methods?

The choice of document sharing and encryption methods directly depends on the general needs of the sender. In some cases, it is enough to ensure the safety of document throughout the sharing process. In others, it is more essential to encrypt documents in such a way that they are protected after delivery to the addressee. Let's take a closer look at solutions to transfer documents securely.

Document Compression Tools

There are plenty of means of compressing documents into a single archive file, and many of the proposed solutions involve the use of some form of encryption. This option protects the materials of the archive. Usually, a password is set during the compression process, and anyone who would like to access the archive can only do so with this password.

One of the most glorious methods for creating archives of compressed files is the zip compression method. It is used by almost all archivers. One of the most common zip compression tools today is the WinZip application. It can be used as a standalone program, built into Windows Explorer for fast access, and integrated with the Outlook.

PKI

Public Key Infrastructure is original but it works in a way similar to PGP. The system involves the active usage of a pair of keys, namely:

  • public;
  • secret.

Senders use their public key to encrypt info sent to a recipient; after the data is delivered to the recipient, he/she decrypts it using his/her private key.

Sender Based Encryption

Voltage Security has created a new technology called identity-based encryption. In general, it is similar to PKI technology but has an interesting feature. The platform puts to use a private key to decrypt messages but does not use a regular key for encryption. IBE provides for the use of the sender's email address. Thus, when sharing an encrypted message to the recipient, the problem of obtaining his/her key does not arise. It is enough to possess the e-mail address of this user.

Virtual Data Room

Online spaces are becoming the standard method to share data. The Virtual Data Room allows you to do this in most securely. With its help, you can view and print documents presented in electronic form.

Unsecure Documents Sharing Solutions

Nowadays, a plethora of websites allow you to upload documents to the server because this is just one of their functions. To cut a long story short, there are many options for malicious use of the file, and for each of them, there should be an appropriate filter. All this gives the penetration tester a lot of scope for analyzing the vulnerability of a web application and a large number of potentially vulnerable sites.

Here are some options for attacking sites that allow you to upload documents to them:

  • downloading malicious code;
  • uploading files too large to fill the server's storage;
  • embedding in filename tag for XSS;
  • downloading malicious materials that are not executed on the website, but are intended for other users.
