aws-ct-metrics 指令¶
使用此指令可針對 AWS CloudTrail 日誌內的欄位建立統計指標。
預設情況下,它會掃描 eventName 欄位。
我們目前使用此指令來找出哪些 API 呼叫最為常見,以便優先撰寫偵測規則。
指令用法¶
Usage: suzaku aws-ct-metrics <INPUT> [OPTIONS]
Input:
-d, --directory <DIR> Directory of multiple gz/json files
-f, --file <FILE> File path to one gz/json file
Filtering:
-s, --include-sts-keys Include temporary AWS STS access key IDs
--timeline-start <DATE> Start time of the events to load (ex: "2022-02-22T23:59:59Z)
--timeline-end <DATE> End time of the events to load (ex: "2020-02-22T00:00:00Z")
--time-offset <OFFSET> Scan recent events based on an offset (ex: 1y, 3M, 30d, 24h, 30m)
--file-date-from <DATE> Filter files by start date based on AWSLogs S3 path date structure (ex: "20240101")
--file-date-to <DATE> Filter files by end date based on AWSLogs S3 path date structure (ex: "20241231")
Output:
-F, --field-name <FIELD_NAME,...> The field(s) to generate metrics for. Comma-separate or repeat to aggregate several in a single scan, e.g. -F sourceIPAddress,userAgent [default: eventName]
-C, --clobber Overwrite files when saving
-G, --geo-ip <MAXMIND-DB-DIR> Add GeoIP (ASN, city, country) info to IP addresses [alias: --GeoIP]
-o, --output <FILE> Save the results to a file
-t, --output-type <FORMAT,...> Output format(s) (only used with -o): csv (default), json, jsonl, duckdb. Comma-separate or repeat to write several at once, e.g. -t csv,duckdb [default: csv] [possible values: csv, json, jsonl, duckdb]
