Understanding these vulnerabilities is essential for maintaining the integrity and confidentiality of cloud resources.

Top 10 GCP Vulnerabilities in 2024

Now, lets dive into the most critical vulnerabilities facing GCP environments in 2024.

1. Misconfigured Identity and Access Management (IAM)

Identity and Access Management (IAM) in GCP is a critical security component that determines who can access specific resources within your environment. However, misconfigurations in IAM settings—often a result of negligence or a lack of understanding—can open the door to unauthorized access, privilege escalation, and data breaches.

Impact of Misconfigured IAM:

High-profile data breaches involving misconfigured IAM settings.
Unauthorized access and data exfiltration risks.

How to Address IAM Misconfigurations:

Apply the principle of least privilege (PoLP).
Audit IAM permissions regularly.
Use multi-factor authentication (MFA) for sensitive accounts.

At Cyserch, our IAM Security Assessments ensure that your IAM policies align with industry best practices and help identify excessive permissions.

2. Insecure API Usage

APIs are the building blocks of modern cloud applications, allowing different systems and services to communicate with one another. However, improper API configurations or insufficient security controls can expose your GCP environment to a variety of threats, including unauthorized access, data exfiltration, and denial-of-service (DoS) attacks.

Real-World Example:

A major cloud provider faced a significant security breach due to misconfigured APIs, exposing millions of users sensitive data. This incident underscored the need for strong API security measures.

How to Secure Your GCP APIs:

Use OAuth 2.0 and API gateways for authorization.
Implement rate limiting to protect against DDoS attacks.
Regularly test your APIs through penetration testing.

Cyserchs API Security Testing Services can help you identify and mitigate security gaps in your GCP APIs.

3. Insufficient Network Segmentation

A common oversight in cloud security is insufficient network segmentation. Without proper segmentation, attackers can move laterally across an entire cloud network once theyve compromised a single component.

Case Study:

A company experienced a massive data breach due to a minor misconfiguration in a low-priority virtual machine, which led to the exposure of sensitive customer information.

Best Practices for Network Segmentation:

Isolate sensitive data and workloads within distinct VPCs.
Implement strict firewall rules between segments.
Use network access control lists (ACLs) to secure communications.

Cyserchs Cloud Penetration Testing helps you assess and improve network segmentation within your GCP infrastructure.

4. Misconfigured Firewalls and Security Groups

One of the most common security risks in GCP is the misconfiguration of firewalls and security groups. Poor configurations can expose your environment to attacks, including DDoS and unauthorized access.

Common Pitfalls:

Leaving unnecessary ports open to the internet.
Failing to update firewall rules as infrastructure evolves.
Overly permissive rules that allow more traffic than necessary.

How to Secure Firewalls and Security Groups:

Disable unused ports to reduce the attack surface.
Apply the least privilege principle to firewall rules.
Automate firewall rule management using Infrastructure as Code (IaC) tools.

Cyserchs Firewall Configuration Assessment will help ensure your firewall settings are robust and effective against attacks.

5. Insecure Storage Configuration

Storing sensitive data in GCP, such as Cloud Storage or Cloud SQL, requires strict security measures. Misconfigurations can lead to unintended exposure of sensitive data, risking compliance and customer trust.

Risks of Insecure Storage:

Data leakage from public-facing storage buckets.
Inadequate encryption leading to data breaches.

Best Practices for Storage Security:

Enable encryption for data at rest and in transit.
Limit access to storage resources based on roles and responsibilities.
Regularly audit storage configurations for compliance.

At Cyserch, our Storage Security Assessment identifies and mitigates risks associated with your GCP storage solutions.
