Data Diode Used As A Unidirectional Gateway
Introduction:
A data diode is a unidirectional security gateway or network. It is also called as a hardware device that allows the data to transfer in only one direction to guarantee information security. It is a one way communication for data transfer in more secure environment to prevent hackers attack. The basic purpose to use the data diodes to ensures the data integrity and confidentiality in critical situations.
Data diode are designed to protect highly sensitive data in industries like Military and Aerospace, nuclear power plants, to send the highly authorized information to security agencies and other critical infrastructure. The main thing that data diode follows is that it will be more secure to any other software system because it is a hardware device attached with a network. Information only move in forward direction and never move in the reverse cycle.
Intelligent data diodes effectively eliminate external points to sending system, preventing intruders and contagious elements from disturbing the networks. For securing networks entire outflow of data with data diode making it impossible for an untrusted network or other security breach along with dangerous malware to access the system and made the harmful changes in it.
Owl data diode allows the organizations to send data in real time to information management systems in industrial, financial and government levels without compromising the security of their networks. In everyday data diode plays an important part in providing the security to the sensitive networks. Most of the sensitive and confidential information are protected from theft through the use of data diodes in the network infrastructure. The tampering of data results in the loss of millions of dollars and countless hours of work in every day. So, the network controller’s preferences in the use of data diode or owl data diodes to avoid all these malicious attacks.
Data diodes ensures the following things in a network channel:
It prevents the hacker attack from outside the network entering into the secure network.
It ensures 100% data leak prevention and due to physical restriction of hardware device no data can leave the network until physical connection breaks.
How Data Diode Works?
Data diode are small hardware device or security gateway sits between two networks. It is placed in between the highly secured critical network and the open network. It is used in between two networks to pass the sensitive and crucial information to ensure the data uniqueness. Data diodes works in one way, it sends information in one direction only and the information never sends back to the first destination from where it received ( this will happen only due the usage of fiber optical connection which prevents the data to move in the opposite direction).
The placement of data diodes in the network is especially for sensitive data transfer which requires internet connectivity. In case of an unprotected data would be vulnerable to intrusions from internet, but by using unidirectional network setup which separates the high side with crucial data and a low side with internet connectivity, the high side can access the internet without exposing the security breach.
Once implemented, a data diode cannot be changed in any way. When a diode is breached, all physical channels for transmission are shut down.
Why we need Data Diodes?
>To secure information and protect from intruders.
>To keep the data confidentiality and integrity.
>To protect from cyber attacks.
>To communicate one way only.
>To guarantee high assurance in data transfer.
