How Secure is the Cloud?

July 4, 2023

Have you ever wondered just how safe the cloud is? In this article, we explore how secure the cloud is and how cloud security can be improved.


What is the Cloud?


The cloud, in the context of business operations, refers to a network of remote servers hosted on the internet that enable the storage, management and processing of data and applications. Unlike traditional on-premises infrastructure, where businesses maintain their own servers and hardware, the cloud offers a scalable and flexible solution.

With cloud ERP software, such as NetSuite, businesses can access computing resources such as storage space with ease, but how safe is the cloud?


Is the Cloud Secure?


The cloud offers security in the following ways:

Data Encryption

The cloud uses encryption techniques to protect your business data. Encryption converts your information into a secret code that can only be understood by authorised individuals. This helps prevent unauthorised access and keeps your data secure.


Physical Security

Cloud service providers have robust security measures in place to protect the physical infrastructure where your data is stored. They employ advanced security systems, including surveillance cameras, access controls and secure data centres. These measures safeguard against physical threats like theft, fire, and natural disasters.


Redundancy and Backup

Cloud providers often have multiple data centres located in different geographical locations. This redundancy ensures that your data is backed up and accessible even if one data centre experiences an outage or disruption. Regular data backups protect against data loss and provide continuity for your business.


Security Expertise

Cloud providers have dedicated teams of security experts who continually monitor and update security protocols. They stay up-to-date with the latest threats and employ industry best practices to ensure your data’s safety. This level of expertise helps protect your business from emerging security risks.


Access Controls

Cloud services offer robust access controls that allow you to manage and restrict who can access your data. You can set up user roles and permissions, enabling you to grant appropriate access levels to employees, clients, or partners. This helps prevent unauthorised users from accessing sensitive information.


Scalable Security

Cloud services allow you to scale your security measures according to your business needs. As your company grows, you can easily adapt and enhance your security protocols without significant infrastructure investments. This flexibility enables you to maintain a secure environment as your business expands.


Compliance and Regulation

Cloud providers adhere to industry-specific compliance standards and regulations. They implement security measures that align with requirements such as HIPAA (Health Insurance Portability and Accountability Act) or GDPR (General Data Protection Regulation). This ensures that your business remains compliant with legal obligations and safeguards customer data.


Advanced Threat Detection

Cloud providers employ sophisticated tools and technologies to detect and mitigate potential threats. They utilise machine learning algorithms and artificial intelligence to identify suspicious activities, anomalies, or potential breaches. This proactive monitoring helps prevent security incidents and provides early detection of any malicious activities.


Disaster Recovery

Cloud services offer robust disaster recovery mechanisms. They can quickly restore your data and applications in the event of a disaster, such as a hardware failure or a cyber attack. With regular backups and efficient recovery processes, the cloud minimises downtime and ensures your business can resume operations swiftly.


How can you Improve your Cloud Security?


Choose a secure cloud provider: When selecting a cloud provider or SaaS platform such as NetSuite, prioritise security features and certifications. Look for providers that comply with recognised security standards such as ISO 27001 or SOC 2 Type II. Additionally, evaluate their data encryption practices, access controls, and incident response procedures to ensure robust security measures are in place.

Implement strong access controls: One of the primary aspects of cloud security is managing user access. Implement a strong authentication mechanism, such as multi-factor authentication (MFA), to add an extra layer of protection. Enforce the principle of least privilege, granting users the minimum level of access required to perform their tasks. Regularly review and revoke access for inactive users or those who have changed roles.


Encrypt Data

Encrypting data is crucial to protect sensitive information from unauthorised access. Cloud providers often offer built-in encryption options, but businesses should also consider implementing additional encryption measures for added security. Encrypt data both at rest and in transit to safeguard against potential data breaches or unauthorised interception.


Maintain Regular Data Backups

Regularly backing up data is essential to mitigate the impact of potential data loss or system failures. Cloud providers usually offer backup solutions, but it’s crucial to establish a comprehensive backup strategy aligned with your business needs. Consider the frequency of backups, off-site storage options, and the ability to restore data efficiently.


Monitor and Audit

Implement robust monitoring and auditing capabilities to detect and respond to security incidents promptly. Monitor user activities, network traffic, and system logs to identify any suspicious or unauthorised behaviour. Leverage security information and event management (SIEM) tools to aggregate and analyse logs for potential threats or vulnerabilities.


Educate and Train Employees

The human element remains a critical factor in cloud security. Conduct regular security awareness training sessions to educate employees about best practices, common threats and phishing prevention. Encourage employees to use strong passwords, avoid sharing credentials, and report any suspicious activities promptly.


Regularly Update and Patch

Keep cloud-based applications and systems up to date by applying security patches and updates promptly. Regularly review the security configurations of your cloud environment to ensure they align with the latest security best practices.


Perform Vulnerability Assessments and Penetration Testing

Regularly assess the security posture of your cloud infrastructure by conducting vulnerability assessments and penetration testing. These assessments help identify vulnerabilities, potential attack vectors, and weaknesses in your security controls. Address any identified issues promptly to enhance your overall security posture.




So in answer to the question “how secure is the cloud”, we would have to say it’s very secure. Cloud service providers take security extremely seriously. The consequences of a data breach could quite literally ruin their business, so it’s in their best interests to make security a top priority which all reputable cloud providers do.
