Bitdefender GravityZone Integrity Monitoring

Why do you need integrity monitoring?

File integrity monitoring is the cybersecurity control that answers a question after the fact: what changed on this system, when, and did anyone approve it. It is also one of the few controls named directly in audit requirements, which is why it is bought as often for the auditor as for the attacker.

PCI DSS Requirement 10.5.5 and ISO 27001 control A.12.4.3 require mechanisms for detecting unauthorized changes to system files and configurations. Without File Integrity Monitoring (FIM), attackers can modify critical files, backdoor configurations and remain undetected for weeks.

GravityZone Integrity Monitoring goes beyond traditional FIM - it monitors files, registries, applications and configurations in real-time, categorizes events and provides contextual recommendations, reducing alert fatigue.

How does it work?

Real-time Monitoring

Continuous scanning with immediate change detection:

• File and directory monitoring (creation, modification, deletion)
• System registry change tracking
• Newly installed or modified application detection
• System and network configuration monitoring

Configurable rules

Flexible rulesets tailored to organizational needs:

• Monitored path and file type definition per endpoint
• Authorized change whitelisting (patching, deployments)
• Different policies for production, dev and staging servers
• Exclusions reducing false positives

Categorization and response

Intelligent event prioritization instead of alert flooding:

• Automatic change categorization (critical, important, informational)
• Contextual action recommendations for each event
• Automatic corrective actions (e.g., file restoration)
• Manual response with audit trail

Key features

Monitoring

• Real-time File Integrity Monitoring (FIM)
• Registry monitoring (Windows)
• Application monitoring (installation, update, removal)
• Configuration monitoring across endpoints

Compliance

• Automatic event mapping to regulatory requirements
• PCI DSS reports (Requirement 10, 11)
• ISO 27001 reports (A.12.4)
• HIPAA, GDPR, NIST 800-53 coverage

Operations

• Intuitive dashboard with change overview
• Event filtering and search
• GravityZone console integration
• SIEM data export

Supported platforms

Operating systems: Windows Server, Linux

Deployment: add-on to GravityZone Business Security Enterprise

Integration: native with GravityZone console, SIEM export

Who is it for?

• PCI DSS-compliant companies - FIM is a compliance requirement
• Organizations with ISO 27001 - infrastructure change control
• Financial and healthcare institutions - HIPAA, sector regulations
• Companies with critical infrastructure - unauthorized modification detection

What an auditor asks about first

A monitoring rule that reports every change is the same as no rule at all — nobody reads it after the first week. Three decisions turn FIM from an alert source into evidence:

• Which files are actually in scope. Binaries, configuration and scheduled tasks answer to an attacker; log files answer to disk space.
• What counts as an approved change. Without a change window or a ticket reference, every deployment looks like an intrusion.
• Who reviews the exceptions, and how often. This is what an auditor asks about, and the answer cannot be “the tool records it”.

Mapping controls to a specific requirement is work we do in PCI DSS certification preparation and in ISO 27001 implementation.
