Three Top Cloud Security Challenges Facing Companies

With technology innovation comes new threats and risks.

Cloud technology revolutionized the way companies manage their systems and data over the past decade. Where information was previously stored primarily on local devices and servers, it is now commonly stored and remotely accessed via cloud services.
 
The ever-changing technology landscape, however, may expose an organization to new security risks. Managing those risks can present significant challenges, especially for companies with constrained information security resources and/or limited experience with cloud-based technologies.

 

Here are three of the top cloud security challenges companies face:

 

Companies need to be diligent about ensuring only authorized users can access their data. Now that data is routinely stored and accessed remotely, it can be an increasingly attractive target to bad actors.  No longer are physical barriers a primary means of controlling access to company data.
 
Companies have several tools at their disposal to protect against unauthorized access, including:

• Multifactor authentication, which requires a user to submit two or more pieces of authentication information to gain access to a system (e.g., password and token, or password and a code sent via email or SMS) rather than a password alone;

• Endpoint detection and response (EDR) solutions to protect users’ devices from threats such as viruses, malware ransomware and phishing; and

• Zero Trust solutions that help the organization grant or deny access based on the user’s context (e.g., from where and when are they attempting to access the system).

 
Companies need to determine which methods are appropriate for their organization and users.  Stronger authentication is typically required for administrators and those with access to the most sensitive information.

 

• What data should I keep? The more data a company stores, the more difficult it is to manage. By storing unnecessary yet sensitive data, companies open themselves up to greater risk in the event of a security incident.

• How long do I keep data? Companies should not keep data longer than necessary. But how long is too long? The answer to that question varies based on the nature of the data, to whom the data belongs, changing regulatory requirements, policies and contractual requirements.

• How do I secure the data? Secure encryption of sensitive data is a strong defense against unauthorized access to data. Companies should take advantage of the encryption functionality provided by cloud services. 

 
A practical approach to data life cycle management and encryption of sensitive data can be a key risk mitigation strategy.

 

 
Companies need strong processes and tools in place to detect and manage security incidents, including key steps such as:

• Identify the incident — Quickly identify security events that potentially involve access to systems and sensitive data and initiate the incident response process.

• Contain the incident —Ensure the bad actors are unable to access any other data in the system, and work to disable their access as quickly as possible.

• Assess the impact — Determine what data was vulnerable to or accessed by the bad actor, where that data resided and who has been impacted. Is it a specific customer or group of customers? Was it a vendor system that was compromised? Forensic analysis may be required.

• Notify impacted parties — Make sure that anyone whose data was impacted is notified of the security breach and your company’s efforts to address it in accordance with breach notification legal requirements.

 
Companies need to have processes in place before a security incident happens. Otherwise, they will find themselves scrambling to effectively respond when an incident occurs.

 

What can you do?

These are three of the top challenges that companies face as they seek to manage cloud security. How can you make sure that your company has the right controls in place to address these challenges, particularly if you provide services that process and store sensitive customer data?
 
By seeking third party attestation services, an organization can obtain verification of their security and privacy compliance with industry standards. There are various types of attestation services that you can seek for this purpose. They include:

1. SOC 2 Report: This report includes an examination of an organization’s internal controls related to security and can also cover availability, processing integrity, confidentiality and privacy. SOC 2 focuses on the company’s controls to address a defined set of security and other requirements for services provided to its customers.  For more information, read our summary of SOC reporting.

2. ISO Certification: ISO security and privacy certifications offer validation that your organization’s security or privacy program is operating in accordance with international standards. ISO certification tends to be most applicable to companies with a global customer base. To see recent updates to ISO 27001 and ISO 27002 for 2022, read here.

3. CSA STAR Assessment: This is a program developed by the Cloud Security Alliance (CSA) based on requirements defined in the Cloud Controls Matrix (CCM). CSA STAR was developed specifically to address cloud security risks and requirements. It includes options that companies can pursue based on their needs.

   • Level 1: Self-Assessment.

   • Level 2: Third-Party Audit. This includes STAR Certification which is an expansion of ISO 27001 certification and STAR Attestation which is an expansion of SOC 2 reporting.

More information on CSA STAR can be found on their website.
 
Each of these third-party attestation processes can help a company to evaluate and improve its cloud security practices, including the areas noted above. The resulting independent auditor’s reports can then be shared with customers to address their security concerns.
