High-assurance Network encryptors secure voice, video, and data moving over public and private IP networks

Protecting network transmitted data against cyber attacks and data breaches is imperative for government agencies. Data network eavesdropping, innocent error or technical failure, data tampering and data theft have all become commonplace. The implications of a significant breach are often catastrophic.

 

 

Encryption is a popular and effective method for safeguarding network data. An encryption system is a security device that converts data into a disguised or encrypted form to render it unintelligible to anyone without a decryption key. Its intended purpose is to ensure privacy by keeping the information hidden from anyone for whom it is not intended.

 

The process of encryption hides data or the contents of a message in such a way that the original information can only be recovered through a corresponding decryption process. Encryption and decryption are common techniques in cryptography — the scientific discipline behind secure communications.

 

Many security-conscious companies go one stage further and protect not only their Internet traffic but also their internal networks, corporate backbone networks, and virtual private networks (VPNs) with network level encryption. Only encryption may ensure that your agency’s data remains protected while transmitted across data networks and links.

 

Many different encryption and decryption processes (called algorithms) exist. Especially on the Internet, it’s very difficult to keep the details of these algorithms truly secret. Cryptographers understand this and design their algorithms so that they work even if their implementation details are made public. Most encryption algorithms achieve this level of protection by using keys. In computer cryptography, a key is a long sequence of bits used by encryption and decryption algorithms.

 

Encrypting data as it moves over a network is only part of a comprehensive network data encryption strategy. Organizations must also consider risks to information at its origin — before it moves — and at its final destination. Stealing a car in a parking lot or private garage is much easier than on the freeway while traveling at high speed!
