Data-centric security — what is DCS?
Data-Centric Security is a security model that binds protection policies directly to data and documents.
Control continues to exist even when a file is copied, emailed, stored on another device or shared with a partner.
How is DCS different from DLP?
Data loss prevention (DLP) detects and stops data from leaving the enterprise via email, USB, websites or the cloud.
DCS protects directly at the file and keeps controlling how the file is used after it has been shared. The two solutions complement each other.
How is DCS different from DRM?
Digital rights management (DRM) controls usage rights for a document such as viewing, editing, printing or sharing.
DCS goes further: it protects data throughout its lifecycle, combining encryption, permissions, audit logs and control of documents after they leave their original environment.
What types of data does DCS protect?
DCS protects enterprise files and documents in the following groups:
- Office: Microsoft Office, PDF.
- Engineering: drawings, CAD files, R&D documents.
- Development: source code.
- Business: contracts, quotations, customer data, intellectual property.
The AISA team checks compatibility with specialized software or formats during the survey phase.
How are files protected?
Files are encrypted and bound to a usage-rights policy from the start. The policy clearly defines:
- Who may open the file.
- Who may edit it.
- Who may print it.
- Who may copy it.
- Who may share it.
- How long the file may be used.
Does DCS encrypt files automatically?
Yes. DCS configures automatic encryption according to policy, reducing reliance on manual user actions. Protection runs in the background and does not noticeably change how employees work day to day.
Can I control who may view, edit, print and share files?
Yes. Enterprises can apply the full set of permissions:
- View, edit, print, copy.
- Screenshot, share, forward.
Permissions are set by user, group, department, project or document type.
Can access be revoked after a file has been sent outside?
Yes. With persistent file control (Persistent File Control), enterprises can revoke access to documents remotely in supported configurations. Useful when:
- A file was sent by mistake.
- A project has ended.
- A partner no longer needs access.
- An employee leaves.
Can DCS be deployed on-premise?
Yes. DCS can be deployed in an on-premise environment for enterprises that want to keep data in internal infrastructure — suitable for R&D data, intellectual property or especially sensitive data.
Does DCS support Cloud and Hybrid?
Yes. DCS is architected to fit:
The specific deployment model depends on each enterprise's infrastructure, security requirements and data policy.
Does DCS integrate with Active Directory?
Yes. DCS automatically synchronizes the user directory and department structure via Microsoft Active Directory (AD) or LDAP, and supports importing lists via standard Excel files.
Does DCS integrate with SIEM or SOAR?
Yes. DCS integrates with security monitoring and operations systems:
- SIEM (Security Information and Event Management) — centralizes and analyzes security events.
- SOAR (Security Orchestration, Automation and Response) — automates incident response workflows.
The AISA team confirms the specific integration capability against the systems the customer actually uses.
Does DCS have an API?
Yes. DCS provides an API (Application Programming Interface) by module and deployment architecture, used to integrate with management systems, automation or other enterprise applications.
Does DCS slow down computers?
DCS protects data with minimal impact on the user experience. Real-world performance depends on:
- File type and size.
- The software in use.
- Device and network configuration.
For CAD, R&D or specialized application environments, AISA runs a trial (POC) before wide rollout.
According to the specifications, the impact on workstation CPU resources is under 3%; users notice no delay when opening, saving or editing files.
Do users have to change how they work every day?
Not significantly. Protection policies run automatically in the background — users keep opening, editing and saving files in their familiar workflow.
Does DCS support offline work?
Yes. In supported configurations, enterprises grant time-limited offline access — useful for employees who are:
- On business trips.
- Working outside the office.
- Working in areas with an unstable network.
Which encryption algorithm does DCS use?
DCS uses AES-256 (CTR mode) to encrypt file content and RSA-2048 key pairs to wrap and protect keys per account or group. An encrypted file grows by only about 1 KB.
Which operating systems does DCS run on?
Workstations: Windows XP, 7, 8, 10 and 11 (64-bit). Servers: Windows Server 2012 / 2016 / 2019 / 2022.
Does DCS protect documents on NAS / file servers?
Yes. DCS encrypts documents stored on shared NAS / SAN / file servers directly, without requiring any intrusive software on the file server.
