DLP Key Requirements

DLP system should promote business and not hinder it. All data channels must be available to employees,

System Architecture

In our solution server part is either SearchInform NetworkSniffer or EndpointSniffer data interception platform, and client applications used to work with the database and make data breach investigations.

Single search-analytical engine allows using all of the above-mentioned search possibilities in full.

Up to date DLP systems have a client-server architecture.

Network traffic Endpoint

Mirror switch Agent

SearchInform NetworkSniffer is a platform used to intercept data on the level of mirrored traffic, i.e. NetworkSniffer processes traffic not interfering with corporate LAN processes.

IMHTTP Mail

SearchInform EndpointSniffer

is a platform that uses agents installed on user workstations

to intercept traffic.

The main advantage of IMSniffer and MailSniffer working on EndpointSniffer platform is high failure tolerance (data is intercepted even if servers are not available). Interception of data transmitted over secure protocols is also supported.

Skype control

Skype - Encrypted data transmit protocol

Types of possible data leaks over Skype:

1. Voice message2. Text message3. File transfer

Skype control

Preventive measures

1. Skype use policy2. Informing employees of skype data analysis3. Understanding risks and risk groups

Control of Skype requires installation of so called “agent” on the endpoint.

Risk Group:1. Employees who breached data security policies even

once, through other channels2. Employees who rename sensitive files, send password-

protected archives, etc., 3. Employees who post negative comments about

company, top managers, etc., 4. Employees for some reason ignoring their work,5. Employees whose work is closely related to cash flows.
