outgoing messages The quality of preventive DLP controls in a potential leak channel depends on their completeness , i.e. how many possible variations, mechanisms and leak scenarios the DLP system prevents in a given data transmission channel. Here are some examples that explain the criticality of control completeness:
· SMTP mail: inspection of the contents of outgoing outgoing messages
Messages and attachments for any SMTP mail client, not just MS Outlook, Thunderbird and IBM/Lotus Notes;
And attachments when using any web browser, not just Internet Explorer, Firefox and Chrome;
· Instant Messengers: inspection of the content of not only sent files , but also outgoing messages ;
· Content detection: recognition and inspection of text content in images and graphic files – in addition to inspection of the content of text documents.
To effectively prevent data leaks, it is necessary
that both contextual and content-dependent b2b email list mechanisms can be us flexibly and variably in DLP policies. Simply put, the initially permitt use of various data transfer channels (transfer context) should be limit to an acceptable minimum that does not disrupt business processes. And only then, content verification – content filtering – is us to block the transfer of data whose leakage is unacceptable.
It should also be kept in mind that even the most high-class DLP system will be useless if it cannot protect itself from deliberate actions by an insider aim at interfering with the DLP or stopping it. Therefore, our clients require that the DLP system provide reliable protection from user intervention, including with local administrator rights.
DLP systems: human factor under control?
security (IS) specialists, is there are also less expensive and complex the weakest link in the IS provision system. It is afb directory precisely to prevent human errors and deliberate violations of IS policies that information leak prevention systems are design.
