Key takeaway
Combine analysis methods, execution controls, investigation and an agreed response workflow as complementary endpoint safeguards.
Threat surface
Laptops, servers, smartphones and IoT devices can be entry points; available controls depend on the device and supported platform. Fileless attacks, zero-day vulnerabilities and ransomware require observation beyond signatures. Scripts and legitimate system tools are not automatically malware.
Combine static and behavioural analysis
Static analysis extends beyond signatures, and behavioural analysis can also be wrong. Legitimate bulk changes can resemble malicious activity. Interpret findings with the file’s origin and business context; do not run a suspicious file to check it.
| Approach | What it examines | What to consider |
|---|---|---|
| Static inspection | File and code properties without running the sample | A match or absence of one needs interpretation |
| Behavioural analysis | Observed process actions during execution | Suspicious action requires context |
| Combined review | File findings plus observed activity | Assess together and investigate disagreement |
Manage execution and application risk
Application control can reduce attack surface by limiting unapproved software. Validate allow rules and exceptions in a controlled pilot against business applications, user needs and change processes. Activity from allowed software may still require investigation.
Connect visibility and response
Endpoint detection and response (EDR) connects device status and event data with investigation. Clarify collected alerts and logs, integrations, retention and response ownership. Collected evidence informs authorized responders; managed monitoring depends on separate service terms.
