Information exchange about threats and vulnerabilities is fundamental to the success of security response. However, timely and effective distribution can only thrive in an environment that is secure. This requires more than an agreement on a common language and framework as well as an understanding of what can be done with shared data by who.
Sharing, sending and receiving sensitive data – even large file sizes – over the internet in a secure way is what secure exchange of data is all about. The demand for this kind of communication will only grow as organizations continue to expand and collaborate with partners and suppliers across boundaries.
The secure transmission of messages ad-hoc, large and small files will become more essential in everyday business life. In many instances, encryption is a crucial element of communication. For risk of data theft example, encryption of emails is a must in order to ensure that communications are secure.
There are a variety of ways to share, send and receive messages securely. One alternative is to use an encrypted information exchange portal that offers encrypted point-to-point messaging and storage. Another is to use cloud folders in which access to write and read can be granted.
When it is time to have a more organized exchange of information, the NIST document Managing the Security of Information Exchanges provides that the level of protection required for sharing of information must be proportional to the risks it carries. This is to protect the confidentiality, integrity, and availability of information as it travels between different entities.
