python-3.x - 允许 0.0.0.0/0 的所有 SG 列表 - 使用 Python 的 AWS Lambda

Question

我对 lambda 函数和 python 比较陌生。试图完成一个 lambda 函数，它列出了我的 AWS 账户中的所有安全组，这些安全组允许 0.0.0.0/0。感谢是否有人可以提供帮助

我已经尝试过这样做，但它提供了对 0.0.0.0/0 开放的实例，而不是我需要一个具有规则的所有 SG 的列表

import sys
import boto
from boto import ec2
from boto import sns
connection=ec2.connect_to_region("region-name")
connSNS = boto.sns.connect_to_region("region-name")
sg=connection.get_all_security_groups()

listOfInstances=""
messages="Following Instances have port open to all"

def getTag(instanceId):
    reservations=connection.get_all_instances(filters={'instance_id':instanceId})
    for r in reservations:
        for i in r.instances:
            return i.tags['Name']

try:
    for securityGroup in sg:
        for rule in securityGroup.rules:
            global instanceId;
            if (rule.from_port=='0' and rule.to_port == '65535') and '0.0.0.0/0' in str(rule.grants):
                for instanceid in securityGroup.instances():
                    instanceId=str(instanceid)
                    listOfInstances += "Instance Name : " + getTag(instanceId.split(':')[1]) + "\t State:" + instanceid.state + "\t SecurityGroup:" +securityGroup.name + "\n"
                    connSNS.publish(topic='SNS-topic-arn-endpoint',message = messages + "\n" + listOfInstances, subject='ProjectName : Server List with Port Open to all')

except :
    print 'Some Error occurred : '
    print sys.exc_info()
    connSNS.publish(topic='SNS-topic-arn-endpoint',message = sys.exc_info(), subject='script ended with error')

这些行专门查找给定安全组的实例：

            for instanceid in securityGroup.instances():
                instanceId=str(instanceid)
                listOfInstances += "Instance Name : " + getTag(instanceId.split(':')[1]) + "\t State:" + instanceid.state + "\t SecurityGroup:" +securityGroup.name + "\n"

如果您不想要这些实例，请删除这些行并返回安全组本身。
