What is Cloud Security Management? 

Cloud security management is the practice of defending an organization’s cloud-hosted data, infrastructure, and applications from cyber threats. As organizations move more data and applications to the cloud, an effective cloud security management strategy is essential to minimize the risk of data breaches, downtime, and other potential threats to the business.

Key Components of Cloud Security Management

Identity and Access Management (IAM)

Identity and access management (IAM) centralizes visibility and control over identities within an organization’s cloud environment. This centralization makes it easier to implement least-privilege access controls and is a foundational part of a zero trust architecture. Well-managed IAM can also reduce the risk of cloud data breaches by limiting the impact if a user’s account is compromised or if they take actions that could expose cloud data to unauthorized users.

Data Encryption and Protection

Data encryption is one of the most effective methods of protecting against data breaches since it renders data unreadable without the correct decryption key. However, only a fraction of sensitive data is encrypted in the cloud. This increases the risk of data breaches if data is exposed to an attacker due to security misconfigurations or compromised accounts.

Network Security

Cloud environments now host a significant portion of many organizations’ internal and public-facing applications. This means that cloud networks carry sensitive data, and attack traffic may flow over them. Implementing network security best practices — such as encryption of traffic in transit — and deploying network security solutions — such as next-generation firewalls (NGFWs), intrusion prevention system (IPS), and data loss prevention (DLP) — in cloud environments is an essential part of a cloud security strategy.

Compliance and Governance

Cloud environments are subject to regulatory compliance requirements and an organization’s internal security policies. However, the cloud shared responsibility model and other idiosyncrasies of cloud environments may introduce compliance challenges. Companies should have policies, procedures, and solutions in place to ensure compliance with internal and external security requirements.

Incident Response and Business Continuity

Cloud environments introduce complications for corporate incident response (IR) and business continuity (BC) strategies. Many security solutions and IR techniques designed for on-prem environments won’t work in cloud environments. Deploying data and applications in the cloud introduces the risk that an outage of the cloud provider could take down critical systems. A cloud security management plan should include making updates and expansions to IR and BC strategies to address the needs and challenges of cloud environments.

Implementing Cloud Security Management: Best Practices and Strategies

Conducting a Comprehensive Risk Assessment

Companies tailor their cloud deployments to their unique business needs. This allows them to optimize cloud usage – but this also means that every company has a unique cloud risk profile. The first step in developing a cloud security management strategy is to perform a risk assessment to identify the potential cybersecurity risks and business impacts associated with their cloud deployment.

Developing a Cloud Security Policy

Cloud environments differ substantially from on-prem infrastructure due to factors such as the cloud shared responsibility model. Additionally, the high usability of cloud resources increases the risk of shadow IT, where cloud services are used without proper authorization. A cloud security policy should extend the organization’s existing security policies to cloud environments, addressing the unique use cases and security challenges that they introduce.

Implementing Multi-Factor Authentication

Compromised accounts are one of the most common causes of data breaches and other security incidents in cloud environments. Enforcing the use of multi-factor authentication (MFA) for all accounts in cloud environments reduces the potential risk of these incidents by decreasing the probability that an attacker will be able to gain the access they need due to a weak or compromised password.

Regular Security Audits and Penetration Testing

Vulnerabilities and security gaps can creep into an organization’s cloud infrastructure at any time in a variety of ways. Software updates, newly provisioned resources, and configuration updates are all potential sources of cybersecurity risk. Performing regular penetration tests and security audits enables the organization to proactively find and fix these issues before they can be exploited by an attacker.

Continuous Monitoring and Threat Detection

Cloud infrastructure is outside the traditional network perimeter and accessible from the public Internet. This increases the complexity of identifying and addressing cyberattacks unless the organization implements monitoring and threat detection capabilities in the cloud. Since cyberattacks can happen at any time, continuous monitoring is essential to provide the organization with the opportunity to respond to a cyberattack before the damage is already done.

Emerging Trends and Technologies in Cloud Security Management

AI and Machine Learning for Threat Detection

Threat detection is tricky because it involves sifting through large volumes of alert and event data to identify potential threats quickly enough to make a difference. Artificial intelligence (AI) and machine learning (ML) are well-suited to this task due to their abilities to process data and make rapid classifications and decisions. As these technologies mature, they will become a central component of threat detection and response in the cloud and beyond.

Zero Trust Architecture

A zero trust architecture implements the zero trust security model of explicit verification of access requests and least privilege access management. Often, cloud data breaches involve unauthorized access to corporate resources due to an attacker compromising an employee account. With zero trust, this account’s access is limited, and unusual access attempts — such as the attacker’s request — have a high probability of being identified and blocked.

Cloud-Native Security Platforms

Cloud-native systems take advantage of the benefits of the cloud by abstracting away the details of the infrastructure and implementing applications as modular, scalable programs. As cloud-native design becomes more common, organizations will need security solutions that offer the same scalability and address the unique security considerations associated with cloud-native systems.

Confidential Computing

Currently, data can be encrypted while at rest and in transit, but processing data requires decryption, placing it at risk of exposure. Confidential computing closes this security gap, protecting data while it is in use as well. This offers significant potential benefits for industries with highly sensitive data, such as finance and healthcare.

Compliance and Regulatory Considerations

Industry-Specific Regulations (e.g., HIPAA, PCI DSS)

Regulations such as HIPAA and PCI DSS are designed to protect certain types of highly sensitive data (protected health information, payment card data, etc.). In cloud environments, compliance with these regulations can be complicated by the cloud shared responsibility model, where some security responsibilities fall with the service provider, and an organization has limited visibility into, and control over its cloud infrastructure. Organizations will need to ensure that their cloud provider is compliant with applicable regulations and understand their security responsibilities to ensure compliance with the regulations.

Global Data Protection Laws (e.g., GDPR, CCPA)

Data protection laws with global reach, like the GDPR, may introduce requirements regarding cross-border data transfers and data localization. In cloud environments, an organization may not know where its data is stored, which increases the difficulty of complying with these requirements. When selecting a cloud provider and configuring cloud deployments, organizations should not only ensure that data protection controls are in place (encryption, IAM, etc.) but also that cloud data storage doesn’t violate these data transfer limitations.

Cloud Security Certifications and Standards

Organizations looking for additional assurance or proof that their cloud is properly secured can pursue cloud-specific security certifications and standards. For example, the Cloud Security Alliance publishes the Cloud Controls Matrix, which describes best practices for cloud security.

Cloud Security for Multi-Cloud and Hybrid Environments

Unique Challenges of Multi-Cloud Setups

Each cloud provider has their own setup and set of configuration options that an organization needs to properly manage to protect its data and infrastructure against unauthorized access and potential attacks. Multi-cloud environments complicate this task since each environment adds more controls to manage and requirements for specialized expertise. Additionally, hybrid and multi-cloud environments involve data transfers and communication between various on-prem and cloud environments, making it necessary for the organization to map and secure these links against potential attack or disruption.

Strategies for Securing Hybrid Infrastructures

Hybrid cloud environments involve both on-prem and cloud-based infrastructure, taking advantage of the benefits of each. In these environments, it’s often wise to ensure that sensitive data with strict regulatory requirements remains on-prem, where security and compliance are easier to manage. Organizations should also implement solutions to securely link these environments, such as site-to-site virtual private network (VPN) tunnels or SD-WAN.

Unified Security Management Across Environments

With multiple different environments to manage, the potential exists that security policies will be inconsistently applied or enforced, introducing security gaps that an attacker can exploit. Cloud security posture management (CSPM) solutions can help with this by providing the company with a centralized location for monitoring and managing controls across multiple cloud platforms. From a security perspective, network-level solutions, such as SASE, reduce the complexity of security management by deploying security in a consistent environment across an organization’s entire IT ecosystem rather than implementing it on a platform-by-platform basis.

Measuring and Reporting on Cloud Security Effectiveness

Essential Cloud Security Metrics and KPIs

Cloud security metrics and KPIs should be tailored to the organization’s business needs and the types of threats that it expects to face. Some examples could include:

• Percent of cloud data encrypted.
• Mean time to detect and remediate cloud security incidents.
• Percent compliance with applicable regulations (HIPAA, PCI DSS, etc.)
• Number of unpatched vulnerabilities.
• Average time to remediate cloud security misconfiguration.

Creating Effective Security Dashboards

An effective security dashboard is one that allows a security analyst to quickly extract the information needed to make key security decisions. When designing dashboards, key best practices include:

• Defining the right metrics and KPIs.
• Collecting data from relevant sources.
• Designing intuitive visualizations.
• Enabling real-time updates and customization.
• Collect feedback and iterate.

Communicating Cloud Security ROI to Stakeholders

Communicating the value of cloud security to stakeholders requires identifying and reporting the cost savings that it creates for the business rather than allowing it to be framed as a cost center. Some ways that cloud security can reduce costs include:

• Avoidance of costly data breaches and downtime.
• Improved compliance with regulatory requirements.
• Enhanced efficiency due to security centralization and automation.
• Reduced consumption of cloud resources due to blocked attack traffic.

The Future of Cloud Security Management

As cloud adoption grows, it becomes increasingly important for organizations to implement cloud security management policies and strategies. This includes adapting existing security policies and practices to cloud environments and developing plans to address the unique security challenges of the cloud.

As cloud environments, usage, and security threats change, so will an organization’s cloud security requirements. Corporate cloud security management programs should embrace a culture of continuous adaptation and improvement to keep pace with evolving cloud risk.
