Understanding Cloud Security: Protecting Digital Assets in the Cloud Realm.
In the last decade, cloud technology has grown exponentially, becoming indispensable for most businesses, particularly those offering remote or hybrid work environments. According to G2, almost all companies have adopted at least one public or private cloud, and 85% of organizations will adopt a 'cloud-first' approach by 2025. Moreover, over 60% of all corporate data is now stored in the cloud. This data can be found on various cloud service providers such as AWS, Microsoft Azure, Google Cloud Platform, or within SaaS apps like Salesforce, Zoom, Slack, Adobe, Microsoft 365, and HubSpot.
Cloud environments offer numerous benefits, such as greater opportunities for collaboration, speed, agility, and scalability. However, they also create a common avenue for cyber threats. Despite the benefits, cloud-related attacks remain among the top threats for businesses, with 80% experiencing an increase in such attacks. Therefore, businesses must understand how to safeguard their cloud environment to fully capitalize on the cloud's potential without exposing themselves to data breach risks.
Cloud Security: Definition and Importance
Cloud security refers to a set of policies, technology, controls, and best practices designed to protect data, applications, and infrastructure hosted in the cloud. Given the increasing number of successful data breaches in recent years, cloud security is a crucial aspect of any company's digital transformation strategy that cannot be overlooked.
Cloud security is a joint responsibility between the cloud hosting platform and the company utilizing it. The level of responsibility varies based on the cloud computing service model, which can fall under the categories of Infrastructure as a Service (IaaS), Platform as a Service (PaaS), or Software as a Service (SaaS). In IaaS, the customer bears a significant responsibility for security, while SaaS applications reduce the burden on the customer. Regardless of the service model, the provider is responsible for securing cloud infrastructure and any physical data centers or network architectures, while customers typically manage user authentication, data encryption, and security controls within their virtual environments to ensure compliance standards.
While this shared responsibility model can be beneficial, particularly for organizations without the resources to manage cloud infrastructure, it can also lead to a false sense of security. Despite cloud service providers and hosting platforms promoting their security, this layer of protection is insufficient to secure a business's environment. To avoid data breaches, companies must invest in cloud security to protect the data and applications within their cloud environments.
To secure data, applications, and cloud environments from internal and external threats, a cloud security strategy should include:
- A properly configured environment, applications, and policies to maintain the configuration as new devices, applications, and users are added.
- Enhanced data protection through encryption for data at rest and in transit (more on data loss prevention software later).
- Access management controls, such as enforcing the principle of least privilege, multi-factor authentication (MFA), deleting default passwords, investing in employee training, and implementing Identity and Access Management (IAM) tools.
- Continuous security monitoring and audits to identify abnormal activity.
- Threat detection and response software and the development of incident response plans.
- Tools and processes for visibility into interacting applications and devices to ensure IT teams are aware of their environment.
- Network segmentation to prevent the entire ecosystem from collapsing if a single application or segment is compromised.
Cloud Security: Why It Matters
The cloud presents businesses with numerous advantages but also offers threat actors multiple opportunities to access their environment. It significantly expands the attack surface and is an attractive target for hackers. Neglecting to consider appropriate security measures while adopting cloud technology puts businesses at risk of costly breaches or security incidents. According to IBM, the average global cost of a data breach in 2023 was $4.45 million, encompassing factors like reputational damage, fines, lost business, legal fees, ransoms, remediation efforts, and more.
Given the high costs and likelihood of falling victim to a data breach, prioritizing cloud security is essential for companies. Cloud security shields sensitive data, applications, and infrastructure from attacks, unintended data leaks, and compliance issues. It safeguards mission-critical SaaS applications from interruptions while ensuring employees don't gain access to data they shouldn't.
Benefits of Cloud Security
Regardless of a business's choice between cloud-based or on-premises storage solutions, sensitive data must be protected. Neither solution is inherently safer than the other, but transitioning to the cloud offers businesses and their security teams various benefits. Apart from shielding a company from costly breaches or security incidents, cloud security offers:
- Centralized cybersecurity: Unlike on-premises software requiring multiple tools at every location, cloud security consolidates an organization's efforts into one centralized framework, streamlining monitoring across all devices, software, endpoints, and systems.
- Lower costs and scalability: Cloud service providers and SaaS companies provide more affordable, scalable security solutions. Their services limit the costs of maintaining security programs as the company expands.
- Continuous monitoring: With an interconnected environment, businesses achieve greater visibility over their assets, traffic, and data, making it easier to continuously monitor for suspicious activity.
- Compliance benefits: Most cloud providers comply with common regulations, such as NIST 800-53, HIPAA, and GDPR. While businesses remain responsible for cloud compliance within their own environments, having a compliant infrastructure significantly eases compliance maintenance.
- Automation: Many cloud security applications offer automated security services, freeing up time and resources for security and IT teams.
Types of Cloud Security Solutions
To safeguard their cloud environment, companies must invest in cloud security tools or services. These solutions cater to various aspects of cloud security, from specific features to more comprehensive routines. Here are several options to consider when it comes to cloud security:
- Cloud Security Posture Management (CSPM): Addressing the primary cause of data breaches in cloud environments, CSPM tools analyze a company's cloud environment for potential security gaps, misconfigurations, or compliance issues. They automatically remediate misconfigurations and generate reports to prove compliance.
- SIEM (Security Incident and Event Management): Historically a staple within cloud security, SIEM solutions offer a holistic view of all activity within a cloud environment. They collect data from any cloud source, analyze log discrepancies, investigate security alerts, and automatically respond to threats, enabling businesses to respond quickly to detected threats.
- Secure Access Service Edge (SASE): Ideal for businesses with remote employees, SASE solutions allow employees to access their network safely without requiring multiple tools. SASE solutions offer a variety of security features, including firewall-as-a-service (FWaaS), zero-trust network access (ZTNA), software-defined wide area network (SD-WAN), and cloud access security brokers (CASB), making it easier for organizations to handle their cloud and hybrid endpoints.
- Identity and Access Management (IAM): IAM systems enable businesses to control who can remotely access various assets in their cloud environment. Security teams can create rules and policies based on user roles, ensuring that sensitive data is only accessible to those who need it for day-to-day responsibilities.
- Data Loss Prevention (DLP) Software: DLP software monitors and controls the storage and movement of sensitive data in cloud environments, preventing unauthorized access or use and data leaks or exfiltration. If suspicious activity is detected, DLP software can block data when at rest, in transit, or in use.
- Public Key Infrastructure (PKI): PKI is a set of processes, policies, and technologies that secure the electronic transfer of information. PKI allows for the encryption and signing of data using keys and digital certificates for users, devices, and services.
- Cloud Workload Protection Platforms (CWPP): Continuously monitoring cloud workloads (like virtual machines, containers, and serverless functions), CWPPs scan for vulnerabilities and threats to ensure security. They help organizations apply consistent security policies to all workloads, particularly in multi-cloud and hybrid environments and organizations with large development departments.
- Cloud-native Application Protection Platforms (CNAPP): CNAPPs are a collection of end-to-end security and compliance tools designed specifically to protect cloud-native applications. These platforms unify various cloud security capabilities, including vulnerability and misconfiguration scanning, detection and response services, comprehensive workload protection, DevOps tools, and the ability to enforce compliance policies across cloud-native applications.
- Extended Detection and Response (XDR): Extending on Managed Detection and Response (MDR) offerings, XDR tools collect and analyze data from multiple sources, such as networks, endpoints, workloads, and applications to help businesses detect and respond to threats. One advantage of XDR tools is their ability to integrate data from both cloud environments and on-premises systems for more comprehensive threat protection.
