The challenges to prevent data loss are tremendous but it is imperative to improve our methods to mitigate and avert the theft of sensitive data by an insider. With technological advancement, vulnerabilities to sensitive data are on the rise. Therefore, accordingly one has to come up with efficient and effective solutions to stop data loss. With increasing incidents of data breaches, it is even more essential to adopt the latest solutions and methods for data loss prevention.
Data loss prevention (DLP) solutions are essentially automated controls that protect sensitive data at rest, in transit and in use. Just like any other loss mitigation solution, an effective DLP solution considers the what, where and how of data sets to determine what access controls need to be in place and how.
Determining What Data Needs to be Protected
Classification of data is compulsory in order to correctly deploy the solution and thwart the loss. Once classification of data is completed as per the business rules by a team of experts, comprising business process managers, IT managers, legal and compliance specialists, policies can be defined determine what data is critical and hence needs to be protected. Data classification also helps determine policies on role-based access and how data can be accessed.
Determining Points Where Data Needs to be Protected
The next step is to determine points where sensitive data resides. The access points for data loss are usually the endpoints such as servers, workstations, storage or network access points. Depending on the need either endpoint protection or network protection may be required. In certain instances, both may have to be protected.
Endpoint protection is usually the first level of security that organizations implement to protect sensitive data from leaving the endpoints of a network. With endpoint protection, unauthorized users or devices, that do not comply with the security policies, are denied access. This prevents copying, sharing or storing of confidential information either accidentally or intentionally to a third party outside the organization. Only upon verifying the credentials the user is allowed to have access to the data.
The end-point security solutions are available in various formats and as piecemeal or part of a larger solution – but the underlying objective is the same i.e. to monitor and control the information that is being accessed and eventually take actions against any malicious threats.
Zlock – Control Device
Zecurion, a pioneer in DLP products, offers Zlock which is designed to protect against leaks of confidential information at the end-points of the network. Zlock allows organizations to control the use of devices connected to ports and internal devices – including built-in network cards, modems, Bluetooth, etc. as well as local and network printers. Using Zlock, a user can make or print copies of only those files that do not have any sensitive information. With Zlock, administrators can configure access policies for maximum flexibility. ZLock saves a copy of all documents printed or stored in external drives, thus maintaining a solid trail in case any investigation is needed in future.
