From 7c76c408d604429169af1df1db7bbabc120f32d2 Mon Sep 17 00:00:00 2001 From: ashley-lowde Date: Mon, 8 May 2023 13:28:30 +0930 Subject: [PATCH 1/2] Add more detailed listeners, rules, actions to AWS ELBv2 load balancers. Record rules, conditions and actions in the form (ELBV2Listener)-[ELBV2_LISTENER_RULE]-(ELBV2Action). This allows us to analyze the path of requests that are intelligently routed based on HTTP request parameters by AWS Application Load Balancers. --- .../aws_ingest_load_balancers_v2_cleanup.json | 72 ++-- .../intel/aws/ec2/load_balancer_v2s.py | 322 +++++++++++++++++- docs/root/modules/aws/schema.md | 129 ++++++- 3 files changed, 465 insertions(+), 58 deletions(-) diff --git a/cartography/data/jobs/cleanup/aws_ingest_load_balancers_v2_cleanup.json b/cartography/data/jobs/cleanup/aws_ingest_load_balancers_v2_cleanup.json index d278cb047e..c2873a65d4 100644 --- a/cartography/data/jobs/cleanup/aws_ingest_load_balancers_v2_cleanup.json +++ b/cartography/data/jobs/cleanup/aws_ingest_load_balancers_v2_cleanup.json @@ -1,33 +1,45 @@ { - "statements": [{ - "query": "MATCH (:AWSAccount{id: $AWS_ID})-[:RESOURCE]->(n:LoadBalancerV2) WHERE n.lastupdated <> $UPDATE_TAG WITH n LIMIT $LIMIT_SIZE DETACH DELETE (n)", - "iterative": true, - "iterationsize": 100 - }, - { - "query": "MATCH (:AWSAccount{id: $AWS_ID})-[:RESOURCE]->(:LoadBalancerV2)-[r:SUBNET]->(:EC2Subnet) WHERE r.lastupdated <> $UPDATE_TAG WITH r LIMIT $LIMIT_SIZE DELETE (r)", - "iterative": true, - "iterationsize": 100 - }, - { - "query": "MATCH (:AWSAccount{id: $AWS_ID})-[:RESOURCE]->(:LoadBalancerV2)-[r:MEMBER_OF_EC2_SECURITY_GROUP]->(:EC2SecurityGroup) WHERE r.lastupdated <> $UPDATE_TAG WITH r LIMIT $LIMIT_SIZE DELETE (r)", - "iterative": true, - "iterationsize": 100 - }, - { - "query": "MATCH (:AWSAccount{id: $AWS_ID})-[:RESOURCE]->(:LoadBalancerV2)-[r:EXPOSE]->(:EC2Instance) WHERE r.lastupdated <> $UPDATE_TAG WITH r LIMIT $LIMIT_SIZE DELETE (r)", - "iterative": true, - "iterationsize": 100 - }, - { - "query": "MATCH (:AWSAccount{id: $AWS_ID})-[:RESOURCE]->(:LoadBalancerV2)-[:ELBV2_LISTENER]->(n:ELBV2Listener) WHERE n.lastupdated <> $UPDATE_TAG WITH n LIMIT $LIMIT_SIZE DETACH DELETE (n)", - "iterative": true, - "iterationsize": 100 - }, - { - "query": "MATCH (:AWSAccount{id: $AWS_ID})-[:RESOURCE]->(:LoadBalancerV2)-[r:ELBV2_LISTENER]->(:ELBV2Listener) WHERE r.lastupdated <> $UPDATE_TAG WITH r LIMIT $LIMIT_SIZE DELETE (r)", - "iterative": true, - "iterationsize": 100 - }], + "statements": [ + { + "query": "MATCH (:AWSAccount{id: $AWS_ID})-[:RESOURCE]->(n:LoadBalancerV2) WHERE n.lastupdated <> $UPDATE_TAG WITH n LIMIT $LIMIT_SIZE DETACH DELETE (n)", + "iterative": true, + "iterationsize": 100 + }, + { + "query": "MATCH (:AWSAccount{id: $AWS_ID})-[:RESOURCE]->(:LoadBalancerV2)-[r:SUBNET]->(:EC2Subnet) WHERE r.lastupdated <> $UPDATE_TAG WITH r LIMIT $LIMIT_SIZE DELETE (r)", + "iterative": true, + "iterationsize": 100 + }, + { + "query": "MATCH (:AWSAccount{id: $AWS_ID})-[:RESOURCE]->(:LoadBalancerV2)-[r:MEMBER_OF_EC2_SECURITY_GROUP]->(:EC2SecurityGroup) WHERE r.lastupdated <> $UPDATE_TAG WITH r LIMIT $LIMIT_SIZE DELETE (r)", + "iterative": true, + "iterationsize": 100 + }, + { + "query": "MATCH (:AWSAccount{id: $AWS_ID})-[:RESOURCE]->(:LoadBalancerV2)-[r:EXPOSE]->(:EC2Instance) WHERE r.lastupdated <> $UPDATE_TAG WITH r LIMIT $LIMIT_SIZE DELETE (r)", + "iterative": true, + "iterationsize": 100 + }, + { + "query": "MATCH (:AWSAccount{id: $AWS_ID})-[:RESOURCE]->(:LoadBalancerV2)-[:ELBV2_LISTENER]->(:ELBV2Listener)<-[:ELBV2_LISTENER_RULE]-(n:ELBV2Action) WHERE n.lastupdated <> $UPDATE_TAG WITH n LIMIT $LIMIT_SIZE DETACH DELETE (n)", + "iterative": true, + "iterationsize": 100 + }, + { + "query": "MATCH (:AWSAccount{id: $AWS_ID})-[:RESOURCE]->(:LoadBalancerV2)-[:ELBV2_LISTENER]->(:ELBV2Listener)<-[:ATTACHED_TO]-(n:ELBV2Rule) WHERE n.lastupdated <> $UPDATE_TAG WITH n LIMIT $LIMIT_SIZE DETACH DELETE (n)", + "iterative": true, + "iterationsize": 100 + }, + { + "query": "MATCH (:AWSAccount{id: $AWS_ID})-[:RESOURCE]->(:LoadBalancerV2)-[:ELBV2_LISTENER]->(n:ELBV2Listener) WHERE n.lastupdated <> $UPDATE_TAG WITH n LIMIT $LIMIT_SIZE DETACH DELETE (n)", + "iterative": true, + "iterationsize": 100 + }, + { + "query": "MATCH (:AWSAccount{id: $AWS_ID})-[:RESOURCE]->(:LoadBalancerV2)-[r:ELBV2_LISTENER]->(:ELBV2Listener) WHERE r.lastupdated <> $UPDATE_TAG WITH r LIMIT $LIMIT_SIZE DELETE (r)", + "iterative": true, + "iterationsize": 100 + } + ], "name": "cleanup LoadBalancerV2" } diff --git a/cartography/intel/aws/ec2/load_balancer_v2s.py b/cartography/intel/aws/ec2/load_balancer_v2s.py index a29e1634ad..1b20831e7e 100644 --- a/cartography/intel/aws/ec2/load_balancer_v2s.py +++ b/cartography/intel/aws/ec2/load_balancer_v2s.py @@ -22,9 +22,30 @@ def get_load_balancer_v2_listeners(client: botocore.client.BaseClient, load_bala for page in paginator.paginate(LoadBalancerArn=load_balancer_arn): listeners.extend(page['Listeners']) + #
