# Esempi di query Security Lake per Amazon VPC Flow Logs
<a name="vpc-query-examples-sourceversion2"></a>

Amazon Virtual Private Cloud (Amazon VPC) fornisce dettagli sul traffico IP da e verso le interfacce di rete nel tuo VPC.

Ecco alcuni esempi di query per Amazon VPC Flow Logs AWS per la versione sorgente 2:

**Traffico specifico Regioni AWS negli ultimi 7 giorni**

```
SELECT *
    FROM "amazon_security_lake_glue_db_us_east_1"."amazon_security_lake_table_us_east_1_vpc_flow_2_0"
WHERE time_dt BETWEEN CURRENT_TIMESTAMP - INTERVAL '7' DAY AND CURRENT_TIMESTAMP 
AND region in ('us-east-1','us-east-2','us-west-2')
LIMIT 25
```

**Elenco delle attività dall'IP di origine `192.0.2.1` e dalla porta di origine `22` negli ultimi 7 giorni**

```
SELECT *

AND src_endpoint.ip = '192.0.2.1'
AND src_endpoint.port = 22
LIMIT 25
```

**Numero di indirizzi IP di destinazione distinti negli ultimi 7 giorni**

```
SELECT 
    COUNT(DISTINCT dst_endpoint.ip) AS "Total"
