# Esempi di query Security Lake per i log della AWS WAF versione 2
<a name="example-queries-waf-sourceversion2"></a>

AWS WAFè un firewall per applicazioni Web che è possibile utilizzare per monitorare le richieste Web inviate dagli utenti finali alle applicazioni e per controllare l'accesso ai contenuti.

Ecco alcuni esempi di query per i log AWS WAF v2 per la versione AWS sorgente 2:

**Pubblica richieste da un IP di origine specifico negli ultimi 7 giorni**

```
SELECT 
    time_dt,
    activity_name,
    src_endpoint.ip,
    http_request.url.path,
    http_request.url.hostname,
    http_request.http_method,
    http_request.http_headers
FROM "amazon_security_lake_glue_db_us_east_1"."amazon_security_lake_table_us_east_1_waf_2_0" 
WHERE time_dt BETWEEN CURRENT_TIMESTAMP - INTERVAL '7' DAY AND CURRENT_TIMESTAMP
AND src_endpoint.ip = '100.123.123.123'
AND activity_name = 'Post'
LIMIT 25
```

**Richieste che corrispondevano a un tipo di firewall MANAGED\$1RULE\$1GROUP negli ultimi 7 giorni**

```
SELECT 
    time_dt,
    activity_name,
    src_endpoint.ip,
    http_request.url.path,

WHERE time_dt BETWEEN CURRENT_TIMESTAMP - INTERVAL '7' DAY AND CURRENT_TIMESTAMP
AND firewall_rule.type = 'MANAGED_RULE_GROUP'
LIMIT 25
```

**Richieste che corrispondevano a un REGEX in una regola del firewall negli ultimi 7 giorni**

```

LIMIT 25
```

**Richieste di AWS credenziali di accesso negate che hanno attivato la AWS WAF regola negli ultimi 7 giorni**

```
SELECT 
    time_dt,
    activity_name,
    action,
    src_endpoint.ip,
    http_request.url.path,
    http_request.url.hostname,

WHERE time_dt BETWEEN CURRENT_TIMESTAMP - INTERVAL '7' DAY AND CURRENT_TIMESTAMP
AND http_request.url.path = '/.aws/credentials'
AND action = 'Denied'
LIMIT 25
```

**Ricevi richieste di AWS credenziali, raggruppate per Paese negli ultimi 7 giorni**

```
SELECT count(*) as Total,
    src_endpoint.location.country AS Country,
    activity_name,
    action,
    src_endpoint.ip,

    AND http_request.url.path = '/.aws/credentials'
GROUP BY src_endpoint.location.country,
