允许 0.0.0.0/0 - 使用 Python 的 AWS Lambda 的所有 SG 列表

Question

我对lambda函数和python相对较新。尝试完成一个 lambda 函数，该函数列出了我的 AWS 账户中允许 0.0.0.0/0 的所有安全组。如果有人可以提供帮助，请不胜感激

我试过这样做，但它给出了对 0.0.0.0/0 开放的实例，相反，我需要具有规则的所有 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')

Answer 1

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"

如果您不需要实例，请删除这些行，而是返回安全组本身。
