Ebs snapshots not public remediation

Using Console

Using CLI

List EBS Snapshots:

aws ec2 describe-snapshots

Identify public snapshots:
- Look for snapshots where the volume permissions include the “all” group.
Modify Snapshot Permissions:

aws ec2 modify-snapshot-attribute --snapshot-id SNAPSHOT_ID --remove-group all

Replace SNAPSHOT_ID with the identifier of the public snapshot. 4. Repeat for other public snapshots:

Repeat the modification command for all public snapshots identified.

Using Python

Here’s a Python script to identify and remediate public EBS snapshots:

import boto3

class EBSSnapshotChecker:
    def __init__(self):
        self.ec2_client = boto3.client('ec2')

    def get_public_snapshots(self):
        failures = []
        response = self.ec2_client.describe_snapshots(OwnerIds=['self'])
        for snapshot in response['Snapshots']:
            if self.is_snapshot_public(snapshot):
                failures.append(snapshot)
        return failures

    def is_snapshot_public(self, snapshot):
        for permission in snapshot.get("Permissions", []):
            if permission.get("Group", "") == "all":
                return True
        return False

    def remediate_public_snapshot(self, snapshot_id):
        self.ec2_client.modify_snapshot_attribute(
            SnapshotId=snapshot_id,
            Attribute='createVolumePermission',
            OperationType='remove',
            GroupNames=['all']
        )
        print(f"Snapshot {snapshot_id} has been remediated.")

# Instantiate the class
checker = EBSSnapshotChecker()

# Get public snapshots
public_snapshots = checker.get_public_snapshots()

# Remediate public snapshots
for snapshot in public_snapshots:
    checker.remediate_public_snapshot(snapshot['SnapshotId'])

This Python script identifies public EBS snapshots by checking if the permissions include the “all” group and then remediates them by removing the permission.Ensure to have appropriate IAM permissions for modifying EBS snapshots if you’re using AWS CLI or Python script.
