The Top 8 Google Cloud Security Tools


1. Identity and Access Management (IAM): Your Digital Gatekeeper


Source: Google Cloud Tech




IAM acts as the digital gatekeeper of cloud services. As part of GCP services, this component plays an integral part in deciding who may access and utilize your cloud services and what tasks can be completed when granted access. Simply put, think of IAM as handing out keys to individual rooms within an enclave; only authorized people possess keys for certain doors.



Key Functions of IAM:


The Identity Access Management (IAM) allows administrators to manage permissions at an extremely granular level, guaranteeing services and users have the appropriate access to resources. Thus it operates:


  • Identity Administration (IAM):


Identity Management allows you to create and administer identities such as service accounts for individual users as well as Google Groups. Each identity has an email address associated with it for easy management.


  • Role-Based Access Control (RBAC):


IAM leverages the RBAC model to assign roles to identities. Roles serve as permission sets that define which actions can be performed by specific resources; Google offers predefined roles like Owner, Editor, and Viewer but you may create custom ones according to your unique requirements.


  • Resource Hierarchy:


IAM organizes resources into hierarchies that begin at an organizational level before branching off to individual resources and projects. You can grant permissions at any point within the hierarchy as they’re passed along automatically to any children’s resources; making management of permissions simpler overall.




  • Access Control:


Google Cloud IAM allows you to restrict who can access, modify, or erase specific resources such as databases, virtual machines storage buckets virtual machines APIs. You have complete control over who can gain entry or alter them in any way.


  • Security


Applying the principle of least privilege allows users and services to acquire all authorization necessary for performing their tasks while minimizing security risk.


  • Compliance


IAM can assist your organization with meeting its compliance obligations by documenting and protecting access to sensitive data and resources.


  • Collaboration:


Identity Access Management facilitates seamless collaboration by giving different departments or team members access at an appropriate level for collaboration on a project while protecting data securely.


Automation Service accounts are an excellent way to integrate applications and automate processes using GCP services, with their own identity and roles that can be assigned as user accounts.


Major Advantages of IAM


There are multiple advantages offered by the IAM for protecting Google Cloud environments:


  • Granular Control:


IAM provides flexible access control through which you can meet the particular needs of the users and service providers.


  • Scalability


As your cloud resources increase, IAM keeps pace to ensure consistent security practices across your environment.


  • Audit and Monitoring:


IAM keeps track of changes to permissions as well as access attempts, providing essential audit reports and monitoring tools.


  • Simplified Administration:


Hierarchies and permission inheritance simplify access control management in complex cloud environments.


  • Compliance Assistance:


IAM can assist your organization in adhering to industry standards and regulations through monitoring access control logs.


2. Cloud Identity-Aware Proxy (IAP): Your Virtual Bouncer


Imagine Cloud Identity-Aware Proxy (IAP) as your virtual bouncer whose primary role is confirming user identities before providing access. Providing extra layers of security to ensure only authorized, verified individuals or entities interact using apps hosted in Google Cloud.


Key Functions of IAP Security Services:


  • Identity Verification


IAP integrates seamlessly with Google Identity to verify the identities of any individuals accessing your apps, using user credentials as well as multi-factor authentication when configured. This verification includes verifying whether MFA is enabled for that individual.


  • Contextual Access


Control IAP allows you to easily create access control guidelines based on the identities of user groups and context such as location or device type. With IAP you can apply fine-grained access control policies.


  • Secure Tunneling


IAP provides secure HTTPS connections among apps to prevent data transmissions from eavesdropping and interception.


Real Life Use Cases of Identity-Aware Proxy (IAP) in Cloud environments:

  • Remote Access Control:


IAP provides secured remote access to GCP-hosted applications and resources from any location while mitigating security risks associated with working remotely. Users may access applications at their leisure from any place without risking being subject to additional threats when working remotely.


  • Fine-Grained Access Control:


IAP allows organizations to set access control rules tailored to user identities and circumstances – increasing security without diminishing usability.


  • Protection Against Unauthorized Entry:


Unauthorized users from accessing sensitive software or information by verifying user identities before providing access.


  • Zero Trust Security:


IAP adheres to a zero-trust security model by not placing trust solely in users or devices based on where their devices may be found. Instead, it conducts continuous checks against identity verification as well as context to detect breaches in security.


Advantages of IAP


  • Robust Authentication: With IAP in place, only users with authenticated credentials and multi-factor authentication enabled can gain entry to your applications.
  • Contextual Access Control: Create policies that can adapt to various access scenarios and deliver improved security without creating additional burdens.
  • Simplified Security: IAP’s compatibility with GCP services reduces configuration burden; additionally, third-party solutions may offer added protection to applications.

5. Google Cloud Key Management Service (KMS): Protector of Secrets


Source: Google Cloud Tech





Enterprises can manage encryption keys for various Google Cloud services they utilize to accomplish cryptographic tasks with the help of Google Cloud Key Management Service (KMS), which is offered by Google.


Launched in January 2017, Google Cloud KMS allows users to generate, use, rotate and destroy Advanced Encryption Standard (AES)-256 encryption keys for protecting cloud data. In addition, enterprises may use Google Cloud KMS for managing other types of encryption keys needed for protecting API tokens and user credentials encrypting them for enterprises as well.

Google Cloud KMS, part of Google Cloud Platform (GCP), enables customers to manage encryption keys for data they store on GCP, while administrators can use it for bulk data encryption before it is stored. Google has designed this service with industries regulated for how they store and secure sensitive data, like financial services and healthcare providers, in mind.


How does Google Cloud KMS Work?


Cloud KMS stores AES-265 encryption keys in a five-level hierarchy. At its top level – GCP Project – identities and access rights management roles for accounts associated with specific cloud projects associated with organizations or departments within them, as well as geographically distributed data centers that handle requests to Cloud KMS resources at this level. Organizations may store geographical locations of their data centers that handle requests to Cloud KMS resources at this level while its Location level can store encryption keys specific to these locations or globally accessible so all locations associated with that project can access them easily.


KeyRings provides a way to host groups of CryptoKeys within an organization and location. Each KeyRing belongs to a project and sets permission levels for the CryptoKeys it holds, so each KeyRing contains CryptoKeys with similar permission levels. A CryptoKey is a cryptographic key with specific purposes that may change as encryption levels change – thus giving rise to CryptoKeyVersion as the last tier in its hierarchy.


Google Cloud KMS includes a REST API for developers, so they can access KMS functions for listing, creating, destroying, and updating encryption keys – ideal for enterprises that manage large numbers of keys as employees come and go or change roles within an organization. In addition, specific encryption keys can also be used to encrypt/decrypt data with specific keys; and set/test IAM policies with ease. Plus there’s even an optional 24-hour delay between key destructions with users being given the chance to restore previous key versions if desired!


Integration With Google Cloud Services


Cloud KMS integrates seamlessly with various Google Cloud services, such as Cloud Identity and Access Management – which handles encryption key authentication – as well as Cloud Audit Logging which tracks administrative access activity – both services being essential when complying with compliance standards or regulations.

Automated and manual key rotation options enable users to set a preset schedule or manually choose when encryption keys change – using either APIs or command line interfaces. Google Cloud KMS can support millions of encryption keys with any number of versions, whether used as a distributed service or within one geographical cloud data center. A few times after creating its counterparts, Amazon Web Services and Microsoft Azure, Google launched its encryption key management service..


6. Cloud Security Scanner: Your Automated Guardian

8. Forseti Security: Your Compliance Partner


Forseti Security is a collection of community-driven open-source tools to assist with increasing security on Google Cloud Platform environments. Composed of core modules that you can enable, configure, and execute independently from each other – along with add-on modules developed by community contributors with unique capabilities – Forseti works together as a foundation from which others may build.


When to Use Forseti Security?


Forseti Security makes sense when you require Security at scale. Manual monitoring might work fine for one or two projects, but as soon as your resources cross multiple projects it becomes increasingly cumbersome to monitor everything manually. Forseti allows creating rule-based policies to codify your security stance; then if anything unexpected changes occur action will be taken such as notifying you and potentially even automatically reverting back to its previous state if something changes unexpectedly.


Overall, Forseti provides you with the tools necessary to ensure that your security governance is by clear, understandable rules.


How Forseti Security Works?

To install Forseti Security, the core modules are deployed and configured so they take an initial snapshot of GCP resources and monitor for changes in access policies as well as notify you.


Inventory can save an inventory snapshot of all of your GCP resources into Cloud SQL for easy reference and to keep a historical record of what was in your cloud. With this knowledge at your disposal, it becomes much easier to assess all resources in GCP and take measures to conserve resources while reducing costs and mitigating security risk. Inventory can run as often as desired and sends email notifications when updates to resource snapshots are complete.




The Forseti Inventory’s information is utilized by Scanner in order to regularly compare role-based access policies of your GCP resources, with automated audit rules applied by this tool to audit these resources as follows.


Cloud Identity and Access Management (IAM) policies cover organizations, folders, projects, bucket ACLs (Access Control Lists), BigQuery dataset ACLs and Cloud SQL-authorized networks.


Scanner makes it easy to set policies that grant, restrict, or exclude access to resources for specific individuals or domains and ensure they stay consistent across resources. If a violation occurs against any Scanner rule(s), Scanner can save those rule violations to Cloud SQL or Storage to protect you against unintended changes that might take place without your knowledge or approval.




Enforcer uses policies you create to analyze the current state of your Compute Engine firewall with its desired state. It is an on-demand command-line tool that compares policies across all managed projects or selected ones in batch mode and reports any discrepancies using Google Cloud APIs to make any needed adjustments, then displays results accordingly. Policies can either apply specifically to individual projects or serve as organization-wide default policies.


This tool also includes

  • Ongoing enforcement of firewall policies across one project
  • Roll back firewall policies




The Explain add-on module offers visibility into Cloud Identity and Access Management (Cloud IAM) policies to assist with understanding:


  • Who has access to what resources
  • How they interact with them and why, or if necessary why they do not. 
  • What roles grant permission and which are not in line with recent changes.


Email Notifications


Once configured, Forseti Security can send inventory and scanner notifications using SendGrid as the only supported email provider.
