# Hayat
Google Cloud Platform Auditing & Hardening Script ~
# What does that mean "Hayat"?
Well, I had a hard time finding a unique name, honestly. "Hayat" is a Turkish word which means "Life" in English and also my niece's name. Ready to meet her?
😍 😍 😍
----------------------------------------------------------------------------------------------------------------------------
Hayat is a auditing & hardening script for Google Cloud Platform services such as:
- Identity & Access Management
- Logging and monitoring
- Networking
- Virtual Machines
- Storage
- Cloud SQL Instances
- Kubernetes Clusters
for now.
## Identity & Access Management
- Ensure that corporate login credentials are used instead of Gmail accounts.
- Ensure that there are only GCP-managed service account keys for each service account.
- Ensure that ServiceAccount has no Admin privileges.
- Ensure that IAM users are not assigned Service Account User role at project level.
- Ensure user-managed/external keys for service accounts are rotated every 90 days or less.
- Ensure that Separation of duties is enforced while assigning service account related roles to users.
## Logging and Monitoring
- Ensure that sinks are configured for all Log entries.
- Ensure that object versioning is enabled on log-buckets.
## Networking
- Ensure the default network does not exist in a project.
- Ensure legacy networks does not exists for a project.
- Ensure that DNSSEC is enabled for Cloud DNS.
- Ensure that RSASHA1 is not used for key-signing key in Cloud DNS DNSSEC.
- Ensure that RSASHA1 is not used for zone-signing key in Cloud DNS DNSSEC.
- Ensure that RDP access is restricted from the Internet.
- Ensure that SSH access is restricted from the Internet.
- Ensure Private Google Access is enabled for all subnetwork in VPC Network.
- Ensure VPC Flow logs is enabled for every subnet in VPC Network.
## Virtual Machines
- Ensure that instances are not configured to use the default service account with full access to all Cloud APIs.
- Ensure "Block Project-wide SSH keys" enabled for VM instances.
- Ensure oslogin is enabled for a Project.
- Ensure 'Enable connecting to serial ports' is not enabled for VM Instance.
- Ensure that IP forwarding is not enabled on Instances.
- Ensure VM disks for critical VMs are encrypted with CustomerSupplied Encryption Keys (CSEK)
## Storage
- Ensure that Cloud Storage bucket is not anonymously or publicly accessible.
- Ensure that logging is enabled for Cloud storage bucket.
## Cloud SQL Database Services
- Ensure that Cloud SQL database instance requires all incoming connections to use SSL.
- Ensure that Cloud SQL database Instances are not open to the world.
- Ensure that MySql database instance does not allow anyone to connect with administrative privileges.
- Ensure that MySQL Database Instance does not allows root login from any host.
## Kubernetes Engine
- Ensure Stackdriver Logging is set to Enabled on Kubernetes Engine Clusters.
- Ensure Stackdriver Monitoring is set to Enabled on Kubernetes Engine Clusters.
- Ensure Legacy Authorization is set to Disabled on Kubernetes Engine Clusters.
- Ensure Master authorized networks is set to Enabled on Kubernetes Engine Clusters.
- Ensure Kubernetes Clusters are configured with Labels.
- Ensure Kubernetes web UI / Dashboard is disabled.
- Ensure `Automatic node repair` is enabled for Kubernetes Clusters.
- Ensure Automatic node upgrades is enabled on Kubernetes Engine Clusters nodes.
- Ensure Container-Optimized OS (cos) is used for Kubernetes Engine Clusters Node image.
- Ensure Basic Authentication is disabled on Kubernetes Engine Clusters.
- Ensure Network policy is enabled on Kubernetes Engine Clusters.
- Ensure Kubernetes Cluster is created with Client Certificate enabled.
- Ensure Kubernetes Cluster is created with Alias IP ranges enabled.
- Ensure PodSecurityPolicy controller is enabled on the Kubernetes Engine Clusters.
- Ensure Kubernetes Cluster is created with Private cluster enabled.
- Ensure Private Google Access is set on Kubernetes Engine Cluster Subnets.
- Ensure default Service account is not used for Project access in Kubernetes Clusters
- Ensure Kubernetes Clusters created with limited service account Access scopes for Project access.
# Requirements
Hayat has been written in bash script using gcloud and it's compatible with Linux and OSX.
# Usage
git clone https://github.com/DenizParlak/Hayat.git && cd Hayat && chmod +x hayat.sh && ./hayat.sh
You can use with specific functions, e.g if you want to scan just Kubernetes Cluster:
./hayat.sh --only-k8s
