As the workforce becomes mobile, the necessity of USB media is undeniable. Flash drives and hard drives have become a tool of convenience, and a must-have for employees on the move to carry corporate data – both sensitive and massive. While USB media is a necessity for its accessibility and portability, it is these very conveniences that also makes them probe to theft and data leakage.
A core part of endpoint security, USB encryption involves encrypting the USB ports of devices such as laptops and desktops that can be used for unauthorized access of data via USB devices, adapters, and peripherals. These security mechanisms prevent corporate networks from being hacked via plugged-in devices, protect from malware attacks, and ensure secure data transfer outside the enterprise.
Native to almost all the operating systems, the control of the USB ports is not flexible. Therefore, options to apply control are also few. Two ways to implement USB control and encryption are:
Blocking USB media usage: Disabling the USB adapters and ports in all the systems. This is not advisable since most printers and computer accessories use 'system's USB ports.
Built-in encryption: Purchasing USB devices with built-in encryption algorithms, or manually encrypting the file systems before providing it to users.
USB encryption vault: Automatically encrypting all confidential data, both enterprise and personal, that are transferred to USB storage devices
Shadow logging of data while transfer from the system to the USB, to keep a log and copy of the data transferred via USB.
For more exceptional control over allowed devices and file types, enterprises resort to third-party applications, which are robust and provide controls with varying degrees of granularity. For example, admins can block specific devices on specific ports by setting a rule on devices that should be allowed on ports. Admins can further finetune and provide user-based access by whitelisting some devices linked to a user.
Enterprises need to follow a 4-step approach to implement USB control and secure data leak at endpoints.
Monitoring access to systems and networks by employees can prevent a data breach. Some of the standard measures that can be implemented are as follows:
While it is good to have in-house security teams, they are not enough when it comes to defending organizations against cybercrime. Enterprises need to deploy third-party data leak solutions to protect against constantly evolving and escalating cyber threats. While implementing a solution, enterprises should consider
Security and data loss prevention should be a part of each employee's education. All the employees, including the C-level executives, should understand the consequences of unsecured data and access to corporate systems. The IT department should educate on how to secure files when using cloud-based services.
To deliver these capabilities, typical data leak prevention software includes features such as:
