GCP security checklist is vital for securing organizational controls and access rights. It allows the users to implement certain restrictions or controls for protecting GCP organizations. Bobcares as part of our Google cloud platform support Service can give you a detailed note on the GCP security list and can answer all questions no matter the size.

GCP security

Securing the GCP environment necessitates addressing what users allow to perform. Implementing organizational-wide controls. Protecting the GCP organization by providing appropriate security policies and safeguarding the GCP apps.

As a starting point for developing a safe organization, consider the following steps:

Checklist

For convenience the steps are divided into two parts:

Step 1

1. Firstly, managing Identities – Control the identities from a central location. Use groups to make administration easier. To centrally regulate who can SSH into the VMs, use os login. Then, enable and manage the I AM role configurations. After that, apply the principle of least privilege. This is one of the primary GCP security checklist strategies.
2. Then, create new roles if the default IAM roles do not meet the use case.
3. When using Custom roles, begin with a pre-defined role.
4. Be careful of the operating costs associated with employing bespoke roles.
5. After that Implement break glass access for elevated jobs such as the organization admin role, which will result in more strict auditing of their use.
6. Then, Use Organization policies to implement organizational-wide standardization.
7. Network controls enable you to build traffic-based boundaries.
8. Subnets define logical boundaries based on a subnet range. Then explicitly permit traffic between subnets. This is the first set of steps for the GCP security checklist.

Step 2

1. The next step in the GCP security checklist is the Firewall configuration. Firewalls control what traffic is allowed between a source and a destination. So Configure firewall rules between VMs using service accounts. After that create a shared VPC to enable network administration from a single location. And, use security zones to offer a layered defense.
2. Securing infrastructure — Use a defense-in-depth approach, starting with GCP platform features and advancing inwards by building security measures appropriate for the use case.
3. To safeguard internet-facing applications, use global load balancing in conjunction with Cloud Armor.
4. IAP is used to manage user access to web-facing apps.
5. To manage authenticated calls to APIs, use API proxies such as Cloud endpoints or Apigee edge.
6. After that make cloud storage buckets are inaccessible to the general public. IAM can be used to manage access.
7. Take caution with downloaded security keys. This is one of the important steps in the GCP security checklist. Implement a procedure to rotate secrets to avoid unintentional loading of secrets into private and public repositories.
8. Encryption requirements – If trusting Google to manage the encryption needs isn’t enough for the use case, use the keys. Using KMS, encrypt the secrets and downloaded keys.
   Data security — data classification — Implement IAM roles to restrict access to the datasets and use the DLP API to classify and redact data. Examine data access. That lineage and location are crucial.
9. Inventory — Recognize the GCP resources. Use Forseti and/or the Cloud security command center.
10. Auditing and alerting – These are often the first signals that anything is wrong. Configure audit logging and alarms using Stackdriver.
11. Data categorization — The DLP API can classify and redact sensitive data.
12. Use the incident replies to ensure compliance ( see operational efficiency)
13. Break glass access

    Conclusion

    To conclude the GCP security checklist set up the GCP controls are vital for any institution to manage the access controls easily. It allows the users to keep their environment secure from external sources.
