What is cloud security?
Cloud security refers to the methods and tools used to protect data and applications stored, processed, and transmitted in cloud environments. Picture cloud computing as a vast network of servers, databases, and software accessible over the internet.
As more businesses move their operations to the cloud, the importance of safeguarding data becomes critical. Cloud security involves various strategies and technologies aimed at ensuring the confidentiality, integrity, and availability of data. It’s not just about regular data protection anymore, it’s also about focused cloud data protection.
A vital aspect is information protection, which focuses on implementing measures to keep data safe throughout its lifecycle in the cloud. In essence, cloud data protection is about ensuring that data hosted in cloud environments is protected from unauthorized access, data breaches, and other security threats. We’ll discuss specific steps organizations can take to protect their data in the cloud below.
Risks associated with storing data in the cloud
Based on IBM’s Cost of a Data Breach Report, 82% of breaches in 2023 involved data stored in the cloud. We’ll let that sink in for a moment…
By implementing robust security measures and adhering to best practices, organizations can mitigate risks and protect their most valuable asset—their data.
So, let’s talk about why cloud data protection matters in more detail:
- Data breaches: Weak access controls, misconfigurations, and vulnerabilities in cloud infrastructure can lead to unauthorized access and data breaches. Attackers exploit these weaknesses to gain unauthorized access to sensitive data stored in the cloud.
Examples of data breach scenarios include unauthorized access to cloud storage buckets, exploitation of misconfigured permissions, and compromised user credentials leading to unauthorized data access or exfiltration.
- Data loss and corruption: Malware, human error, hardware failures, and software errors can result in the loss of critical data stored in the cloud. Without aadequate backup and recovery measures, organizations risk permanent data loss and operational disruptions.
Examples of data loss and corruption scenarios include accidental deletion of critical data, software bugs, and cyber attacks such as ransomware encrypting data stored in cloud storage.
- Compliance violations: Non-compliance with regulatory requirements can lead to severe legal and financial consequences. Failure to protect sensitive information, maintain data privacy, and adhere to data retention policies can result in regulatory fines, legal penalties, and reputational damage.
Examples of compliance violations and legal implications include unauthorized access to personally identifiable information, failure to comply with data protection laws such as GDPR, and exposure of confidential or proprietary data leading to lawsuits and litigation.
Additionally, organizations operating in regulated industries must adhere to specific data protection laws and industry standards. For example, healthcare organizations must comply with the HIPAA, while financial institutions must adhere to the PCI DSS.
Data breaches can have far-reaching consequences, especially in today's world where news of a data breach spreads swiftly, eroding customer confidence and loyalty. And those are tough – sometimes even impossible – to gain back. For many businesses, a data breach can mark the beginning of their downfall.
What types of data do businesses store in the cloud and why?
In the cloud, sensitive data covers various information assets that hold value and need safeguarding from unauthorized access, disclosure, and manipulation. Common types of sensitive data stored in the cloud include:
- Financial records: Client credit card information, banking transactions, and financial statements are sensitive financial data that must be protected to prevent fraud and financial loss. Data loss incidents in the financial industry are some of the costliest out there at USD 5.9 million per data breach (based on IBM’s 2023 Cost of a Data Breach Report).
- Customer information: Personally identifiable information (PII), including names, addresses, phone numbers, and email addresses, is commonly stored in the cloud by organizations across various industries from manufacturing and automotive to education and government.
- Intellectual property: Trade secrets, patents, copyrights, and proprietary business information represent valuable intellectual property assets that require protection against theft and unauthorized disclosure.
- Health records: Electronic health records, medical histories, and patient diagnoses contain sensitive health information protected by healthcare privacy regulations such as HIPAA. The particularly sensitive nature of this information makes data breaches in the healthcare industry by far the most expensive out of any industry: USD 11 million per data breach!
- Legal documents: Contracts, agreements, and legal correspondence may contain sensitive legal information subject to attorney-client privilege and confidentiality requirements.
Businesses choose to store sensitive data in the cloud for various reasons, ranging from scalability and accessibility to cost-effectiveness and operational efficiency. Cloud storage solutions provide flexible storage options and universal access to data from any device or location, empowering organizations to streamline operations, foster collaboration, and cut infrastructure expenses. However, it's crucial to balance the convenience and perks of cloud storage with robust security measures to counter the inherent risks linked with storing sensitive data in shared, multi-tenant cloud environments.
Understanding the data lifecycle
Data in motion refers to data that is actively being transmitted between devices, networks, or systems. Examples include emails, file transfers, and real-time communications such as video conferencing.
Encryption protocols such as TLS and SSL are commonly used to secure data in motion by encrypting communication channels between clients and servers. HTTPS encrypts web traffic to protect sensitive information transmitted over the internet, including login credentials and financial transactions.
Data at rest pertains to information that resides in storage repositories or databases and remains inactive until accessed by authorized users or applications. Examples include files stored on servers, databases, and cloud storage platforms.
Disk encryption solutions encrypt data at rest to protect sensitive information stored on hard drives or storage devices. Stored data is safeguarded by encrypting files, databases, or entire storage volumes to prevent unauthorized access.
Data at use is information that is actively being processed or accessed by users or applications. Examples include data accessed by users in web applications, databases queried by applications, and files opened by users for editing or viewing.
Application-level encryption techniques, such as database encryption and file-level encryption, can protect data at use by encrypting sensitive information within applications or databases. Access controls and authentication mechanisms restrict user access to data based on predefined permissions and roles.
Cloud security: A shared responsibility model
Cloud security is often misunderstood, with many believing that cloud service providers (CSPs) shoulder all responsibility for securing data and applications in the cloud. However, the reality is quite different. Cloud security operates on a shared responsibility model, where both CSPs and cloud customers, like your business or organization, play crucial roles in implementing security controls. This is how:
CSP responsibilities
Maintenance of cloud infrastructure, including data centers, networks, servers, and storage systems by implementing the following:
- Network security: Network segmentation, firewalls, intrusion detection and prevention systems, and distributed denial-of-service (DDoS) protection to safeguard cloud networks and infrastructure from unauthorized access.
- Data encryption: CSPs offer data encryption capabilities to encrypt data at rest and in transit.
- Identity and access management (IAM): IAM solutions enable organizations to manage user identities and implement authentication mechanisms such as multi-factor authentication to prevent unauthorized access to cloud resources.
- Compliance and certification: CSPs adhere to industry standards and regulatory requirements, undergo regular security assessments and audits, and obtain certifications such as ISO 27001, SOC 2, and GDPR compliance to demonstrate their commitment to security and compliance.
Customer responsibilities
Securing data and applications within the cloud environment. This includes implementing DLP solutions, access controls, encryption, and internal data security policies and employee education on the topic of protect sensitive information from unauthorized access or disclosure.
Did you know?
Another common misconception is that cloud environments are less secure than on-premises infrastructure. While cloud environments introduce unique challenges like shared responsibility, multi-tenancy, and dynamic scaling, they also offer robust security features and controls.
