Boost Security With A Cloud Audit For AWS, Google, And Microsoft

Discover how a comprehensive cloud audit can secure your data and optimise your AWS, Google and Microsoft environments.

We provide a Cloud Audit service that checks essential, critical settings and permissions of various cloud resources to identify any deviations from best practices and security standards. This ensures your cloud environment is correctly configured to best practises and can help highlight any configuration flaws that may have been set.

What is a Cloud Audit?

It is essential to ensure that cloud environments are correctly set up and secured as per the highest industry standards. A cloud audit will assess and report any mis-configurations highlighting some of the issues below:

• Security - Passwords, Buckets, Configurations
• User access rights
• Network / Port Configurations / Routing
• Data Protection
• Policies
• Setup

Cloud Audit Security

Cloud audits often centre on an organisation's protective measures, encompassing their operational, procedural, or technological defences employed to maintain the security and privacy of their information systems. When examining cloud environments, auditors typically assess the presence of these defences, evaluate their proper implementation, verify their functionality, and determine their efficacy in countering potential threats.

Furthermore, taking a cloud audit now, especially as much of our most essential data is already hosted in the cloud, will not only enhance security but also provide an extra layer of peace of mind.

Cloud Audit Mis-configuration Checks

• Microsoft Azure covers over 100+ different controls
• Google Cloud covers over 80+ different controls
• Amazon AWS covers over 80+ different controls

These checks ensure a thorough and detailed analysis of system configurations.

Cloud Audit Overview

The rapid adoption of cloud computing has revolutionised how businesses manage and deploy their IT infrastructure. Notably, leading cloud service providers like Google Cloud, Microsoft Azure and Amazon AWS offer an extensive range of services and capabilities designed to meet diverse business needs.

That said, with great power comes significant responsibility. In particular, cloud security remains a critical concern, and the proper configuration of cloud resources is key to building a robust defence against cyber threats. To address these challenges, this article delves into the importance of cloud security audits, identifies common misconfigurations, and highlights cyber-attack vulnerabilities within these three major cloud platforms.

Moreover, given the vast amount of critical data now stored in the cloud, it is crucial to ensure that both your environment and your customers' environments are configured and secured in alignment with industry best practices.

Advantages doing a Cloud Audit

1. Managing Access Control: When employees join, transition, or leave an organisation, their access rights must be reviewed and updated. Security assessments help by identifying outdated permissions and ensuring new employees receive only the privileges they need.
2. Ensuring Secure Cloud Access: Cloud audits confirm that employees and users connect to resources safely. For example, they might require VPNs or encrypted connections, which reduce the risk of unauthorised access.
3. Securing APIs and External Tools: Cloud platforms often integrate with APIs and third-party tools. These integrations can introduce vulnerabilities. Security assessments identify risks in these tools and recommend fixes, helping to secure the entire ecosystem.
4. Verifying Backup Strategies: Cloud backups are convenient, but misconfigurations can weaken their effectiveness. Cloud audits check if backups are performed regularly and verify that proper safeguards protect them.

How a Cloud Audit can help?

Security configuration involves managing and regulating the settings of an information system to ensure safety and minimise risk. It is a critical component of any organisation's cybersecurity strategy.

Hackers and malicious actors relentlessly target unsecured cloud environments and systems. They exploit known vulnerabilities and, if successful, breach the system. Once inside, they can make unauthorised modifications, putting sensitive data and operations at risk.

Establishing a golden standard for your systems and continuously monitoring for violations can help organisations quickly identify and address potential threats. This proactive approach reduces the likelihood of breaches and ensures systems remain secure.

Regularly testing your configuration not only strengthens your systems but also provides opportunities to improve security. This practice makes it significantly harder for attackers to succeed, safeguarding both your organisation and your customers.

Understanding the value of robust security configuration is essential. Recognising its importance ensures organisations prioritise the protection of their systems and data.

Security Compliance

Maintaining compliance with industry regulations and standards is vital for businesses across sectors. Conducting a comprehensive audit helps ensure cloud resources meet all relevant security and privacy requirements, reducing risks and supporting operational integrity.

Risk Mitigation

Identifying misconfigurations allows organisations to proactively address potential security risks. By resolving vulnerabilities early, businesses can prevent costly financial and reputational damage caused by cyberattacks.

Data Protection

Securing sensitive data is critical. A detailed configuration audit verifies access controls and encryption settings, helping to minimise the risk of data breaches and ensuring robust protection.

Resource Optimisation

Cloud audit can helps optimise resource usage and manage costs effectively. By identifying and eliminating unused or unnecessary resources, organisations can achieve significant cost savings.

Some Common Cloud Audit Findings

Inadequate Identity and Access Management (IAM) Policies

Improperly configured IAM policies can grant excessive privileges, providing users or services more access than needed. This increases the risk of unauthorised access, data exposure, and compromise of critical resources.

Unsecured Cloud Storage Buckets

Misconfigured Google Cloud Storage buckets with overly permissive access controls can allow unauthorised users to view, modify, or delete sensitive data, posing significant security risks.

Weak Network Security

VPC (Virtual Private Cloud) settings with weak firewall rules or misconfigured network access controls can expose critical backend services to external attacks, increasing the risk of security breaches.

 Unrestricted API Access

Unsecured APIs or those with excessive permissions can result in data leaks, denial-of-service attacks, and unauthorised access to sensitive resources, compromising system security.

Improperly Configured Network Security Groups (NSGs)

Incorrectly configured Network Security Groups (NSGs) can permit unauthorised network traffic, exposing virtual machines and other resources to significant security vulnerabilities.

Weak Authentication and Authorisation

Weak authentication mechanisms and poorly defined role-based access controls (RBAC) can enable unauthorised access and facilitate privilege escalation attacks, jeopardising system security.

Unprotected Storage Accounts

Misconfigured Azure Storage accounts with unrestricted access permissions can result in data leakage or unauthorised modifications to stored data.

Open Database Ports

Leaving database ports open to the public internet may enable attackers to gain unauthorised access to databases, potentially leading to data breaches or ransomware attacks.

Privilege Escalation

Lack of proper access controls and monitoring may enable attackers to escalate privileges within environments, potentially gaining control over critical resources.

Cloud Best Practises

Organisations leveraging cloud audit services from Google, Microsoft, or Amazon must prioritise security by adhering to their respective platform frameworks. Maintaining continual vigilance is essential for protecting sensitive IT systems and data, ensuring security remains at the forefront.

To effectively reach our target audience, we must focus on the specific individuals who can benefit most from this service. Our cloud audit is tailored for professionals working with Amazon AWS, Google Cloud, or Microsoft Azure solutions. This includes:
