AN2057: Analytic 2057
Monitor device alarms for program downloads, although not all devices produce such alarms.
Monitor for protocol functions related to program download or modification. Program downloads may be observable in ICS automation protocols and remote management protocols.
Consult asset management systems to understand expected program versions.
Monitor devices configuration logs which may contain alerts that indicate whether a program download has occurred. Devices may maintain application logs that indicate whether a full program download, online edit, or program append function has occurred.
Analyst context for executives and security teams
AN2057 is an ICS detection analytic focused on noticing when control-system programs are downloaded or modified. For business leaders, the practical issue is change assurance: unauthorized or unexpected logic changes can affect operational reliability and safety, but visibility is often uneven because not all devices generate alarms for these events.
Executive priority
Prioritize this analytic where operational continuity depends on trusted controller or automation logic. Leaders should ask whether the organization can prove what program version should be running, detect a download or online edit, and reconcile device activity against approved change records. This supports incident decision-making, compliance evidence, and cyber-physical risk governance, but the supplied ATT&CK object does not specify platforms, tactics, or guaranteed detection coverage.
Technical view
SOC, IR, OT engineering, and detection teams should validate whether device alarms, ICS automation protocol activity, remote management protocol activity, device configuration logs, and application logs expose program download or modification events. Key event types to confirm include full program download, online edit, and program append functions. Asset management data should be used as the baseline for expected program versions so alerts can be compared against authorized changes.
Likely telemetry
- Device alarms indicating program downloads or related change activity
- ICS automation protocol functions associated with program download or modification
- Remote management protocol functions associated with program download or modification
- Device configuration logs containing program download alerts
- Device application logs showing full download, online edit, or program append events
Detection direction
- Validate which devices actually produce alarms for program downloads; the official text notes that not all devices do.
- Correlate protocol-observed download or modification functions with device logs and approved change windows.
- Compare observed program versions or change events against asset management systems and expected program baselines.
- Tune triage to distinguish approved engineering activity from unexpected modification events.
- Document blind spots where devices, protocols, or logs do not expose program download evidence.
Mitigation priorities
- Establish and maintain asset-management baselines for expected program versions.
- Ensure operational change processes capture authorized program downloads, online edits, and appends.
- Enable and retain available device configuration and application logs where supported.
- Review monitoring coverage for ICS automation and remote management protocol functions related to program modification.
- Use gaps identified by this analytic to prioritize logging, asset inventory, and change-control improvements.
Analyst notes and limits
This is an ATT&CK ICS detection analytic, not a technique description. Its value is strongest as a coverage validation checklist for OT monitoring and engineering change assurance. There are no supplied relationships, tactics, labels, aliases, or platforms, so interpretation should remain focused on the official description.
Official detection logic is not provided, and the object states that not all devices produce relevant alarms. Local device capabilities, protocol visibility, log retention, asset inventory quality, and change-management records are required to determine practical coverage.

Mirrored ATT&CK source object
The raw object is retained through the mirrored ATT&CK source bundle and object hash. The raw endpoint returns the exact object from the mirrored bundle when available.
External references and citations
MITRE external references are preserved separately from Glexia analysis so citations remain traceable to their original source records.
