BCS ITNow 201403 - Data Loss Prevention
- 1. DLP is often thought of as a technology
that simply stops all unauthorised
information flows once it has been
installed. In reality, DLP should be part of
information life cycle management and
focus on ensuring organisations can share
the information it needs to, both internally
and externally, in a correct, accountable
and secure manner. Data loss is then also
prevented as a beneficial by-product.
Even well funded and resourced
organisations can find this challenging in
practice, especially against a motivated
insider, such as in the case of Edward
Snowden and the NSA, as although external
barriers may be strong, internal ones are
often weak. Without all-encompassing
policies and procedures, no amount of
technology can completely counteract
inadvertent or deliberate exposure and
exfiltration of information and data.
To enable robust inter-organisational
collaboration, we need common policies
for identity proofing and verification (IPV) of
organisations, people and devices, issuance
of credentials, authentication, authorisation
so that interoperability can be obtained.
One leading initiative is the non-profit
organisation British Business Federation
Authority (BBFA) (federatedbusiness.org)
that is working towards enabling such
federated trust.
BBFA is working with both private
and public sector organisations towards
standards-based and interoperable IPV,
strong authentication and authentication,
federation and PKI bridge policies,
procedures and mechanisms, as it
INFORMATION SECURITY
recognises that without these no technology
can meet the real needs of customers and
end users. BBFA is also involved in secure
information sharing initiatives, such as the
HMG Cyber Information Sharing Partnership
(CISP) and Multinational Alliance for
Collaborative Cyber Situational Awareness
(MACCSA).
