ayushpriya10/imdshiftAutomatisiert die Migration von AWS-Workloads von IMDSv1 zu IMDSv2, um SSRF-Angriffe zu entschärfen. Erkennt IMDSv1-Nutzung in EC2, ECS, EKS, Lightsail und mehr, mit Hop-Limit-Updates und SCP-Empfehlungen.
AWS-Workloads, die auf den Metadaten-Endpunkt angewiesen sind, sind anfällig für Server-Side Request Forgery (SSRF)-Angriffe. IMDShift automatisiert den Migrationsprozess aller Workloads zu IMDSv2 mit umfangreichen Funktionen, die verbesserte Sicherheitsmaßnahmen zum Schutz vor diesen Angriffen implementieren.
MetadataNoToken-CloudWatch-Metrik in angegebenen RegionenMetabadger ist ein älteres Tool, das zur Erleichterung der Migration von AWS EC2-Workloads zu IMDSv2 verwendet wurde.
IMDShift bietet mehrere Verbesserungen gegenüber den Fähigkeiten von Metabadger:
git clone https://github.com/ayushpriya10/imdshift.git
cd imdshift/
python3 -m pip install .
git clone https://github.com/ayushpriya10/imdshift.git
cd imdshift/
python3 -m pip install -e .
Options:
--services TEXT This flag specifies services scan for IMDSv1
usage from [EC2, Sagemaker, ASG (Auto Scaling
Groups), Lightsail, ECS, EKS, Beanstalk].
Format: "--services EC2,Sagemaker,ASG"
--include-regions TEXT This flag specifies regions explicitly to
include scan for IMDSv1 usage. Format: "--
include-regions ap-south-1,ap-southeast-1"
--exclude-regions TEXT This flag specifies regions to exclude from the
scan explicitly. Format: "--exclude-regions ap-
south-1,ap-southeast-1"
--migrate This boolean flag enables IMDShift to perform
the migration, defaults to "False". Format: "--
migrate"
--update-hop-limit INTEGER This flag specifies if the hop limit should be
updated and with what value. It is recommended
to set the hop limit to "2" to enable containers
to be able to work with the IMDS endpoint. If
this flag is not passed, hop limit is not
updated during migration. Format: "--update-hop-
limit 3"
--enable-imds This boolean flag enables IMDShift to enable the
metadata endpoint for resources that have it
disabled and then perform the migration,
defaults to "False". Format: "--enable-imds"
--profile TEXT This allows you to use any profile from your
~/.aws/credentials file. Format: "--profile
prod-env"
--role-arn TEXT This flag let's you assume a role via aws sts.
Format: "--role-arn
arn:aws:sts::111111111:role/John"
--print-scps This boolean flag prints Service Control
Policies (SCPs) that can be used to control IMDS
usage, like deny access for credentials fetched
from IMDSv2 or deny creation of resources with
IMDSv1, defaults to "False". Format: "--print-
scps"
--check-imds-usage This boolean flag launches a scan to identify
how many instances are using IMDSv1 in specified
regions, during the last 30 days, by using the
"MetadataNoToken" CloudWatch metric, defaults to
"False". Format: "--check-imds-usage"
--help Show this message and exit.
