How To Conduct A Cloud Security Assessment

Technology changes rapidly. Since 1980, CTS Companies has seen the landscape shift from mainframe terminals to on-premise servers, and now, to the cloud. While the way we deliver technology has evolved, our commitment remains the same: helping you figure out which technology you need to solve business problems in a simple and reliable way.

Moving your operations or data to the cloud offers flexibility and scalability. However, it also changes how you must approach security. Many business owners assume that because their data is with a major cloud provider, it is automatically secure. This is a dangerous misconception. Security in the cloud is a shared responsibility. Conducting a proper cloud security assessment is the only way to ensure your business is protected against modern threats.

This guide outlines a straightforward approach to assessing your current cloud security posture.

Understanding the Shared Responsibility Model

Before you begin auditing your systems, you must understand the rules of the road. In almost every cloud agreement, the provider (like Microsoft, Amazon, or Google) is responsible for the security of the cloud. This includes the physical data centers, the hardware, and the software infrastructure.

You, the customer, are responsible for security in the cloud. This includes your data, your user identities, your devices, and your configuration settings. If an employee uses a weak password and gets hacked, the cloud provider is not at fault. A security assessment focuses on the parts of the cloud you control.

If you need assistance navigating these responsibilities, our team provides expert guidance on cloud services in Michigan to ensure you aren’t leaving doors open.

Step 1: Inventory Your Cloud Assets

You cannot protect what you do not know exists. The first step in any assessment is establishing visibility. In many organizations, employees may sign up for applications or storage solutions without IT approval—a phenomenon known as “Shadow IT.”

To conduct a thorough inventory:

• List all Cloud Providers: Identify every platform in use, from major infrastructure (IaaS) to software applications (SaaS) like email, CRM, and file-sharing tools.
• Map Data Flows: Determine where your sensitive data originates, where it is stored, and who has access to it.
• Identify Shadow IT: Review network logs or financial statements to find unauthorized software subscriptions.

Having a clear map of your digital footprint allows you to apply consistent security policies across your entire IT infrastructure.

Step 2: Evaluate Identity and Access Management (IAM)

Identity is the new perimeter. In a cloud environment, firewalls matter less than user credentials. If a hacker steals a username and password, they can access your data from anywhere in the world. At CTS, we look at security through six distinct categories, and password policies are near the top of that list.

During your assessment, ask the following questions:

• Is Multi-Factor Authentication (MFA) Enabled? MFA should be mandatory for all users, not just administrators. It is the single most effective step to prevent unauthorized access.
• Are You Following Least Privilege? Users should only have access to the files and systems necessary to do their jobs. Review user roles and remove administrative privileges from standard user accounts.
• What is the Offboarding Process? When an employee leaves, their access to cloud applications must be revoked immediately. Test your process to ensure no “zombie accounts” remain active.

Proper identity management is a core component of cybersecurity in Michigan and essential for keeping your business safe.

Step 3: Review Data Protection and Backup Strategies

Data loss can happen due to malicious attacks, accidental deletion, or service outages. A robust cloud security assessment must verify that your data is recoverable.

CTS has specialized in data backup and recovery in Michigan since the late 90s. We know that simply having data in the cloud is not a backup strategy. Syncing files is different from backing them up.

Check Encryption Standards

Ensure that your data is encrypted both at rest (when it is stored on the server) and in transit (when it is moving between your computer and the cloud). Most providers offer this, but it often requires configuration.

Verify Backup Integrity

Do not assume your backups are working. Your assessment should include a test restore. Can you bring a deleted file back? How long does it take? If you are hit with malware, can you roll back to a clean state? Effective ransomware protection relies on the ability to restore data without paying a ransom.

Step 4: Analyze Network and Remote Access Configurations

The ability to work from anywhere is a primary benefit of the cloud, but it also increases risk. You need to assess how your team connects to your resources.

Review these specific areas:

• VPN Usage: Are employees connecting via a secure Virtual Private Network (VPN) when accessing critical systems from public Wi-Fi?
• Endpoint Security: The cloud is safe, but is the laptop accessing it safe? Ensure all devices have up-to-date antimalware and web filtering installed.
• Firewall Settings: Cloud servers have virtual firewalls. Check that no unnecessary ports are open to the public internet.

If you are managing a hybrid environment with on-premise equipment, consider how your physical office connects to the cloud. We provide comprehensive assessments for IT services in Detroit, MI, covering everything from cabling to cloud configurations.

Step 5: Inspect Activity Logs and Monitoring

Security is not a “set it and forget it” task. You need to know what is happening in your environment in real-time. Cloud providers generate massive amounts of log data, recording every login, file access, and configuration change.

Your assessment should determine if anyone is actually looking at these logs. Look for:

• Failed Login Attempts: A high number of failed logins often indicates a brute-force attack.
• Impossible Travel: If a user logs in from Michigan and then logs in from another country ten minutes later, that is a red flag.
• Large Data Transfers: Unexpected spikes in data downloading could indicate data theft.

Establishing a baseline for normal activity helps you spot anomalies quickly.

The Value of a Professional Partner

Conducting a cloud security assessment internally can be challenging. It requires specialized knowledge and time that many internal IT teams simply do not have. Furthermore, it is often difficult to grade your own work objectively.

CTS Companies operates as a Managed Service Provider in Michigan, offering a spectrum of support options. We do not force you into a single type of partnership. Whether you need a one-off security project, reactive support, or a full IT department to handle the heavy lifting, we adapt to your needs.

We look at security holistically. Our approach covers physical security, policies, antimalware, and remote access. We help you identify gaps in your CTS cloud services and fix them before they become liabilities.

Taking the Next Step

A cloud security assessment provides a roadmap. It tells you where you are vulnerable and what you need to fix. However, the assessment is only valuable if you act on the findings.

If you are unsure where to start, or if your current IT setup feels overwhelming, CTS is here to help. We provide a service that just works. We handle the complexity so you can focus on running your business.
