Synology file access log auditing with ADAudit Plus
Know who accessed, modified, or deleted every file on your Synology NAS, and when, from where, and why it matters.
Track every file operation
Capture reads, creates, modifications, deletions, renames, moves, and copy-paste events across all Synology shares. Each record includes the user, originating machine, IP address, and exact timestamp.
Get real-time alerts on critical activity
Receive immediate notification when a mass deletion or ransomware-pattern event occurs. Alerts route directly to your team and can auto-create tickets in your ITSM tool.
Long term data retention
Store Synology file activity audit data for as long as you want, and ensure all audit requirements are met.
Noise reduction
Exclude specific files from auditing based on the local path, file type, user name, or process name.
Meet compliance requirements
Pre-built report sets mapped to SOX, HIPAA, PCI-DSS, GDPR, and ISO 27001 mean your next audit starts with the data already organised. Custom report profiles let you combine specific users, actions, and filters into saved views for recurring reviews.
Detect anomalous file behavior
Machine learning baselines per user flag spikes in file deletions, modifications, or access attempts at unusual times, without requiring manually configured thresholds.
Centralised multi-NAS reporting
Manage Synology alongside NetApp, QNAP, Amazon FSx, Azure File Share, and 12 other NAS types from a single console. Report on a specific Synology server or generate a report on a particular action across your entire NAS environment.
Export and schedule audit reports
Export any Synology file audit report to CSV, PDF, HTML, or XLSX. Schedule delivery to auditors, IT managers, or compliance teams by email, on any recurring interval you define.
Synology file access log auditing
Synology NAS devices hold shared drives, departmental repositories, and often sensitive business data that multiple users access daily. Knowing who did what to which file, and being able to prove it, goes well beyond what the built-in Log Center was designed to handle.
ADAudit Plus connects to your Synology NAS and begins capturing file access events from day one. Every operation, including reads, creates, modifications, and deletions, is recorded with the full context an IT admin needs: user identity, source machine, IP address, and timestamp. Reports are pre-configured and ready to run, and alerts fire the moment a critical event occurs.
What ADAudit Plus audits on Synology NAS
| Audit area | What ADAudit Plus captures |
| File reads | Every successful read event, with user, machine, IP, and file path |
| File creates | New files created on any monitored Synology share |
| File modifications | Files modified, with who changed them, when, and from which machine |
| File deletions | Files deleted, with full user and source context |
| File moves and renames | Files moved between locations or renamed, with old and new paths |
| Copy-paste operations | Files copied and pasted, with source, destination, and acting user |
| Failed access attempts | Denied reads, writes, and deletes, captured as distinct, reportable events |
| User and process summaries | File activity aggregated by user and by process, with counts per operation type |
Track every file operation across Synology shares
ADAudit Plus captures the full range of file activity monitoring on Synology NAS with the source user identity, source machine, IP address, file path, and timestamp. You can also break down file activity by the process that performed it, helping you distinguish interactive user activity from automated mass modifications.
- Track all file and folder changes including reads, creates, modifications, deletions, renames, moves, and copy-paste events, in a single console.
- Leverage the advanced filtering capabilities to view actions in a specific share, by a particular user, or in a single source machine.
- Identify processes accounting for the highest volumes of file accesses.
Maintain an audit trail of file changes in your Synology NAS environment.
Get real-time alerts on critical Synology file activity
For events like mass deletions, permission changes on sensitive shares, or ransomware-pattern file modifications, the window between the event and your response matters. This is where alerts come in handy. With ADAudit Plus' real-time alerts for Synology NAS, you can:
- Receive notifications when a file or folder deletion event fires, so data loss can be assessed before the change propagates or backups cycle.
- Alert administrative stakeholders when there is rapid, high-volume file modifications consistent with encryption activity
- Execute custom, scripted responses so you can isolate the malware-affected machines before the spread continues.
- Auto-create a ticket in your ITSM tool so your technicians can respond to incidents quickly with full context.
Detect anomalous file activity with user behavior analytics
Threshold-based rules catch what you anticipated. User behavior analytics catches what you did not. ADAudit Plus builds a machine-learning baseline of normal file activity per user on your Synology NAS and flags deviations automatically. This helps you detect critical events like:
- File modification volumes that deviate from a user's established pattern.
- File activity at an unusual time, when a user outside their normal working hours, without requiring you to define what "normal" is for each person.
Meet compliance requirements
SOX, HIPAA, PCI-DSS, GDPR, GLBA, FISMA, and ISO 27001 all require evidence that access to sensitive data is monitored, that changes are recorded, and that audit trails are retained. Synology NAS devices holding financial records, patient data, or cardholder data fall within scope for most of these standards.
- ADAudit Plus includes pre-configured compliance report sets that map Synology file audit events to each standard. Reports cover file access activity and user activity summaries.
- Build custom report profiles that combine specific users, audit actions, folders, and date ranges into saved views for recurring compliance reviews.
- Schedule compliance reports for automatic delivery to auditors or compliance officers on any interval.
- Export any report to PDF, CSV, HTML, or XLSX to match the format your auditors require.
Why Synology Log Center falls short
Synology's built-in Log Center works for basic device-level troubleshooting. It was not built for centralised, compliance-grade security auditing.
- Log Center stores event data locally on each Synology device. In a multi-NAS environment, reviewing activity means logging into each device separately, with no consolidated view across your NAS auditing estate.
- Retention in Log Center is limited by local storage. When capacity fills, older events are overwritten. Compliance frameworks that require years of audit data retention cannot be satisfied this way.
- Log Center has no real-time alert capabilities for file-level events. You cannot configure notification when a mass deletion occurs or when changes happen in a sensitive share.
- Log Center does not produce compliance-mapped reports. Preparing for a SOX or HIPAA audit means manually exporting and assembling log data rather than running a pre-built report.
ADAudit Plus picks up where Log Center stops: centralised collection across all your NAS devices, long-term audit data retention, real-time alerting, and compliance-ready reports, all from a single console.
