# Amazon VPC 流日志的安全湖查询示例
<a name="vpc-query-examples"></a>

Amazon Virtual Private Cloud (Amazon VPC) 提供有关进出 VPC 网络接口的 IP 流量的详细信息。

以下是AWS源版本 1 的 Amazon VPC 流日志的一些查询示例：

**最近 7 天的具体AWS 区域流量**

```
SELECT *
    FROM amazon_security_lake_glue_db_us_east_1.amazon_security_lake_table_us_east_1_vpc_flow_1_0
    WHERE eventDay BETWEEN cast(date_format(current_timestamp - INTERVAL '7' day, '%Y%m%d%H') as varchar) and cast(date_format(current_timestamp - INTERVAL '0' day, '%Y%m%d%H') as varchar) 
      AND region in ('us-east-1','us-east-2','us-west-2')
    LIMIT 25
```

**过去 7 天内来自源 IP `192.0.2.1` 和源端口 `22` 的活动的列表**

```
SELECT *
    FROM amazon_security_lake_glue_db_us_east_1.amazon_security_lake_table_us_east_1_vpc_flow_1_0
    WHERE eventDay BETWEEN cast(date_format(current_timestamp - INTERVAL '7' day, '%Y%m%d%H') as varchar) and cast(date_format(current_timestamp - INTERVAL '0' day, '%Y%m%d%H') as varchar) 
      AND src_endpoint.ip = '192.0.2.1'
      AND src_endpoint.port = 22
    LIMIT 25
```

**过去 7 天内不同目标 IP 地址的数量**

```
SELECT
    COUNT(DISTINCT dst_endpoint.ip) 
    FROM amazon_security_lake_glue_db_us_east_1.amazon_security_lake_table_us_east_1_vpc_flow_1_0
    WHERE eventDay BETWEEN cast(date_format(current_timestamp - INTERVAL '7' day, '%Y%m%d%H') as varchar) and cast(date_format(current_timestamp - INTERVAL '0' day, '%Y%m%d%H') as varchar) 
    LIMIT 25
```

**过去 7 天内源自 198.51.100.0/24 的流量**

```
SELECT * 
    FROM amazon_security_lake_glue_db_us_east_1.amazon_security_lake_table_us_east_1_vpc_flow_1_0
    WHERE eventDay BETWEEN cast(date_format(current_timestamp - INTERVAL '7' day, '%Y%m%d%H') as varchar) and cast(date_format(current_timestamp - INTERVAL '0' day, '%Y%m%d%H') as varchar) 
    AND split_part(src_endpoint.ip,'.', 1)='198'AND split_part(src_endpoint.ip,'.', 2)='51'
    LIMIT 25
```

**过去 7 天内的所有 HTTPS 流量**

```
SELECT
      dst_endpoint.ip as dst, 
      src_endpoint.ip as src, 
      traffic.packets 
    FROM amazon_security_lake_glue_db_us_east_1.amazon_security_lake_table_us_east_1_vpc_flow_1_0
    WHERE eventDay BETWEEN cast(date_format(current_timestamp - INTERVAL '7' day, '%Y%m%d%H') as varchar) and cast(date_format(current_timestamp - INTERVAL '0' day, '%Y%m%d%H') as varchar) 
      AND dst_endpoint.port = 443
    GROUP BY 
      dst_endpoint.ip, 
      traffic.packets, 
      src_endpoint.ip 
    ORDER BY traffic.packets DESC 
    LIMIT 25
```

**按过去 7 天内发送到端口 `443` 的连接的数据包数量排序**

```
SELECT
      traffic.packets,
      dst_endpoint.ip
    FROM amazon_security_lake_glue_db_us_east_1.amazon_security_lake_table_us_east_1_vpc_flow_1_0
    WHERE eventDay BETWEEN cast(date_format(current_timestamp - INTERVAL '7' day, '%Y%m%d%H') as varchar) and cast(date_format(current_timestamp - INTERVAL '0' day, '%Y%m%d%H') as varchar) 
      AND dst_endpoint.port = 443 
    GROUP BY 
      traffic.packets,
      dst_endpoint.ip
    ORDER BY traffic.packets DESC
    LIMIT 25
```

**过去 7 天内 IP `192.0.2.1` 和 `192.0.2.2` 之间的所有流量**

```
SELECT
      start_time, 
      end_time, 
      src_endpoint.interface_uid, 
      connection_info.direction,
      src_endpoint.ip,
      dst_endpoint.ip,

      traffic.bytes
    FROM amazon_security_lake_glue_db_us_east_1.amazon_security_lake_table_us_east_1_vpc_flow_1_0

      AND(
        src_endpoint.ip = '192.0.2.1'
        AND dst_endpoint.ip = '192.0.2.2')
      OR (
        src_endpoint.ip = '192.0.2.2'
        AND dst_endpoint.ip = '192.0.2.1')
    ORDER BY start_time ASC
    LIMIT 25
```

**过去 7 天内的所有入站流量**

```
SELECT * 
    FROM amazon_security_lake_glue_db_us_east_1.amazon_security_lake_table_us_east_1_vpc_flow_1_0

      AND connection_info.direction = 'ingress'
    LIMIT 25
```

**过去 7 天的所有出站流量**

```
SELECT * 
    FROM amazon_security_lake_glue_db_us_east_1.amazon_security_lake_table_us_east_1_vpc_flow_1_0

      AND connection_info.direction = 'egress'
    LIMIT 25
```

**过去 7 天内所有被拒绝的流量**

```
SELECT * 
    FROM amazon_security_lake_glue_db_us_east_1.amazon_security_lake_table_us_east_1_vpc_flow_1_0
    WHERE eventDay BETWEEN cast(date_format(current_timestamp - INTERVAL '7' day, '%Y%m%d%H') as varchar) and cast(date_format(current_timestamp - INTERVAL '0' day, '%Y%m%d%H') as varchar) 
      AND type_uid = 400105
