How to send very large files across the web

An email is automatically generated to the recipient or recipients, who then download the file to their computers, PDAs, or other device. To ensure that data is not compromised in either transfer, JustSendOnline employs the Secure Socket Layer (SSL) protocol.

SSL is browser-based protocol, originally developed by Netscape to provide for secure transfer of information between two points on the Internet. Today, it is the most common way e-commerce and other commercial sites protect an end user's confidential information in transit.

SSL works by encryption. A secure website first sends a user's browser a public encryption key, which is used to construct another, unique, non-public encryption key. This key, which is known only to the web server and the user, is then used to protect all subsequent transfers of information. In practice, SLL provides a secure tunnel between two points on the Internet. Files transferred along this tunnel are wrapped in a layer of encryption that makes them impossible for third parties to view or compromise.

2. Data Confidentiality with JustSendIt:-Using its SSL solution, JustSendOnline can ensure complete data confidentiality. The encryption methods it uses are based on keys only available to the user and the server, making it practically impossible to decode the data sent, even if it is intercepted.

3. Data Integrity with JustSendIt: - JustSendOnline SSL solution also ensures data integrity. That means that no outside source can modify data as it travels between an end user and a server. If data is changed in transit, the protocol automatically recognizes the modification and asks the client to resubmit the file.

4. Advantages of JustSendOnline for IT Management
Many other solutions exist for secure file transfer such as Secure FTP, Secure Shell (SSH), and custom products offered by third party vendors. In choosing a file sending solution, companies should not only consider security, but also the Total Cost of Ownership (TCO). The JustSendOnline solution offers a number of benefits that lower costs and reduce the strain on IT departments. These include:
Firewall Friendly Solution

Unlike FTP and SSH, JustSendOnline provides an easy way to transfer large files at a higher level of security. Both Secure FTP and SSH solutions require ports to be opened permanently in a firewall to allow for inbound commands to a network, leaving them vulnerable to attack. Because JustSendOnline SSL solution works with the HTTP protocol on port 443, it does not require a permanently open port. Instead, firewalls dynamically open and close the port for it as needed.

Low Maintenance Set Up

In addition, JustSendOnline requires no resources to set up and maintain. IT departments do not need to track logins and passwords, activating and retiring them as employees come and go.
Cross Platform Access

JustSendOnline solution is inherently cross platform and works on any browser. Even if a recipient is remote and has no access to an FTP client, he or she can still download files securely using any web browser.

III. Physical and IT Infrastructure
In addition to file transfer, JustSendOnline has employed best practices security methods to ensure that customer's files remain secure while stored on its servers. These include everything from the physical security of JustSendOnline datacenters to the firewalls and other measures the company uses to protect its servers from electronic attack. Some of the top features of JustSendOnline infrastructure security include:

Application Management
Applications are the most dynamic part of an IT Infrastructure, since they directly interact with the user. As a result, they require special care to guard against both accidental and intentional damage. JustSendOnline uses only brand-name client, server, middleware, and database applications, specifically hardened and customized for its uses. Every server has a firewall, every router has filtering. They all receive the latest security updates and are constantly monitored against threats.

Datacenter and Security
The setup and surveillance of physical infrastructure plays a vital role in security management. Physical access to a server may allow attackers to circumvent electronic barriers. As a result, JustSendOnline has severely limited access to its datacenter.

Public access to JustSendOnline offices is limited to certain rooms, which are under constant surveillance by the staff. The datacenters do not allow any public access; only identified persons acknowledged by the management may enter them. Their entry and exit time is recorded, and they must not only have a correct password but they also must pass a biometric scan to gain entry.

Multiple datacenters
To ensure that data is never lost, JustSendOnline maintains two separate datacenters, both hardened to resist fire, earthquakes, and other natural disasters.

IV. Additional security options using JustSendOnline
In addition to providing secure transfer via SSL, JustSendOnline also offers a number of optional, out-of-band measures and monitoring activities that can be used to maximize the security of file transfer. The out-of-band features require offline communication as a phone call or email to complete a file transfer. The monitoring activities can help a user check to ensure that no unexpected downloads of a file occur. Users can also quickly delete a file from JustSendOnline servers, if they fear they may have been compromised.

Password-protected downloads
In some cases, a user may require an additional, offline security method to ensure that only a specific person can receive a file. This situation usually arises when the recipient of a file works on a shared computer, shared email account, or in an insecure environment. JustSendOnline helps its customers secure such file transfers with password-protection.

To use password-protection, a user specifies a password during file upload. This password will not be transmitted by JustSendOnline to the recipient. Instead, the file sender must communicate the password by a separate method, such as email or telephone. To download the file, the recipient must enter this password.
