ayushpriya10/imdshiftAutomatiza la migración de cargas de trabajo de AWS de IMDSv1 a IMDSv2 para mitigar ataques SSRF. Detecta el uso de IMDSv1 en EC2, ECS, EKS, Lightsail y más, con actualizaciones del límite de saltos y recomendaciones de SCP.
Las cargas de trabajo de AWS que dependen del endpoint de metadatos son vulnerables a ataques Server-Side Request Forgery (SSRF). IMDShift automatiza el proceso de migración de todas las cargas de trabajo a IMDSv2 con amplias capacidades, lo que implementa medidas de seguridad mejoradas para proteger contra estos ataques.
MetadataNoToken de CloudWatch en las regiones especificadasMetabadger es una herramienta más antigua que se utilizaba para facilitar la migración de cargas de trabajo de AWS EC2 a IMDSv2.
IMDShift realiza varias mejoras con respecto a las capacidades de 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.
