How can you integrate cloud security to existing frameworks?

In my experience, one can also leverage internal and external audit reports to gain insight into the existing control environment and identify strengths and opportunities. It is also crucial to understand the length and breadth of coverage from your existing control framework. This is a key step in understanding your current position before moving on to the next steps of identifying the right framework.

Assessing your curent framework is one of the key requirements of most major frameworks. Examples: ISO 27001 - Clause 5.4.1: "The organization shall determine external and internal issues that are relevant to its purpose and that affect its ability to achieve the intended outcome(s) of its ISMS" ISO 22301 - Clause 5.4.1: "The organization shall determine external and internal issues that are relevant to its purpose and that affect its ability to achieve the intended outcome(s) of its BCMS" NIST CSF v 2.0: "GV.OC - Organizational Context: The circumstances - mission, stakeholder expectations, and legal, regulatory, and contractual requirements - surrounding the organization's cybersecurity risk management decisions are understood"

Security frameworks are definitely the foundation of the Cloud security posture. It might not be 100% applicable to your reality, but if your missing too many controls and best practices, you may be creating something too complex to manage and control.

Generally, Governance Controls of any Standard require organizations to review and assess the suitability of their existing Infosec framework/Program, examples include the following: CC1. Control Environment in Trust Services Criteria - Requires management to actively monitor and evaluate the effectiveness of the control environment and take appropriate actions to address deficiencies and improve over time. Clause 9.3: Management Review in ISO27001 - Requires top management to conduct regular reviews of the ISMS to ensure its continued suitability, adequacy, effectiveness, and alignment with the organization's strategic objectives.

Evaluation of current security policies and practices to identify gaps will help explore the improvement that needs to be made to the existing framework or if it requires total overhauling of the existing framework.

A well-defined security framework provides a clear roadmap for implementing effective security controls, such as identity and access management, data encryption, threat protection, and regulatory compliance.

Approach: To ensure adequate protection of cloud environments, verifying that each framework aligns with industry standards and best practices, such as ISO 27001, SOC 2, GDPR, HIPAA, or CIS benchmarks, is essential. This ensures the framework provides robust security controls and compliance mechanisms to meet regulatory requirements and industry benchmarks. It is also necessary to evaluate the underlying security architecture of each framework to understand how it operates and protects cloud environments. Factors such as the use of encryption, multi-factor authentication, intrusion detection and prevention systems, and secure configuration management should be assessed to determine the effectiveness of the security architecture.

The two main cloud security frameworks are: 1. The Cloud Security Alliance's Cloud Control Matrix. The CCM has been around since 2011 & is now in its fourth release. It is vendor agnostic & provides mapping to other non-cloud focused frameworks including NIST CSF, ISO 27001/2/17/18, CIS v8, & AICPA TSC (SOC 2) 2. FedRAMP: This is essentially NIST 800-53 R5 controls adapted for cloud, but its primary focus is a complex authorization process for US-based institutions working with the Federal government. It is not generally recommended unless you require a Federal 'Authorization to Operate' All other frameworks (ISO 27001, NIST CSF, CIS v8 etc) require adaptation &/or supplementation to be made appropriate for cloud-based deployments.

Choosing a cloud security framework depends on the organisational and compliance requirements. Also depends on the Business and domain or vertical the org is operating.

Selecione uma estrutura de segurança na nuvem que atenda às suas necessidades específicas. Isso pode incluir soluções como AWS Security Hub, Azure Security Center ou Google Cloud Security Command Center, além de outras ferramentas de terceiros. Select a cloud security framework that meets your specific needs. This may include solutions such as AWS Security Hub, Azure Security Center, or Google Cloud Security Command Center, as well as other third-party tools.

Recommended Cloud Security Alliance Domains for organizational alignment are: - Governance Risk Management & Compliance - Audit & Assurance - Supply Chain Management, Transparency & Accountability - Data Security & Privacy Lifecycle Management - Human Resources Security - Identity & Access Management - Logging & Monitoring - Threat & Vulnerability Management - Business Continuity Management & Operational Resilience - Security Incident Management, E-Discovery, & Forensics - Change Control & Configuration Management - Cryptography, Encryption & Key Management - Application & Interface Security - Interoperability & Portability - Infrastructure & Virtualization Security - Data centre Security - Universal Endpoint Management

A integração bem-sucedida requer alinhamento dos domínios de segurança. Mapeie áreas como governança, gestão de identidade, proteção de dados e resposta a incidentes para sua estrutura de segurança na nuvem escolhida. Defina claramente as responsabilidades de cada domínio para garantir uma implementação eficaz. Exemplo: Uma empresa de comércio eletrônico mapeia seus domínios de segurança para a ISO 27001 ao integrar serviços de nuvem em sua operação. Eles atribuem responsabilidades claras para a proteção de dados do cliente ao departamento de conformidade, enquanto a equipe de operações de TI é encarregada da segurança de rede na nuvem.

In my years of safeguarding digital domains, the alignment of security domains within the cloud environment has stood out as a critical endeavor. This intricate dance involves mapping our traditional security domains—such as identity and access management and incident response—to our chosen cloud framework. The complexity of this task is underscored by the shared responsibility model in cloud security, requiring a clear delineation of roles between us, our cloud providers, and third parties. Mastering this alignment not only enhances our security posture but also fosters a culture of accountability and collaboration across all stakeholders.

Integrating cloud security into existing frameworks involves aligning security domains to ensure comprehensive protection. This includes incorporating cloud-specific security controls and practices into existing policies, procedures, and technologies. Key steps include identifying cloud security requirements, evaluating and selecting appropriate cloud security solutions, and integrating them into existing security frameworks. Collaboration with cloud service providers and continuous monitoring and adaptation are also essential for effective integration and ongoing security management.

Aligning security domains crucially integrates cloud security with existing protocols. It promotes consistency, leverages strengths of both frameworks, enhances threat visibility, and ensures adaptability. Ultimately, it strengthens the organization's security posture, safeguarding against cyber threats effectively. This alignment offers benefits like streamlined management, reduced oversight risks, and improved scalability. By creating a unified security front, organizations can navigate modern cybersecurity challenges with confidence.

As with any security framework security controls should be implemented to mitigate identified risks. This is most easily achieved by first establishing a formal Information Security Management System (e.g., along the lines of ISO 27001) which is used to: (i) identify, assess & evaluate information security risks; (ii) design & implement controls; & (iii) continually reassess & improve the effectiveness of the implemented controls to ensure the security (confidentiality, integrity & availability) of the organization is maintained in accordance with established risk tolerance levels.

Secure Identity and Access Management (IAM): Implement strong IAM policies, including the principle of least privilege and multi-factor authentication (MFA). Data Encryption: Ensure that data is encrypted both in transit and at rest within the cloud. Endpoint Security: Extend endpoint security policies to cover devices accessing cloud services. Visibility and Monitoring: Use cloud-native or third-party tools for continuous monitoring and logging of cloud environments.

Securing your cloud? Think toolbox! There are 3 types of controls to protect your data: Policies & Procedures (Admin): The rulebook for cloud security, ensuring everything is done safely. Tech Tools (Technical): Firewalls and alarms to actively prevent or detect attacks. Physical Safeguards (Physical): Security guards for your cloud server room, keeping the hardware safe. Use all three controls to fortify your cloud environment! #CloudSecurity #SecureYourCloud

Ser minucioso nessa etapa compensa muito a longo prazo, em vários aspectos: 1) Definir medidas técnicas e organizacionais adequadas, mas flexíveis e adaptáveis irá ajudá-lo a aderir ao LGPD e a outras leis de proteção de dados que exigem que essas medidas estejam em vigor. 2) Os controles técnicos realmente protegerão seus dados, fluxos de trabalho e lógica de negócios. Especialmente ao usar hiperscalers ou grandes provedores de nuvem.

Depends on the architecture. It also depends on the service offering of the organisation. Need to understand the shared responsibility of “In the cloud and on the cloud “. Also protect using native controls and services. Dash boards and visualisation help in monitoring.

Estabeleça métricas e indicadores de segurança na nuvem para acompanhar regularmente o desempenho e a conformidade. Utilize ferramentas de monitoramento para coletar e analisar dados do ambiente de nuvem.

Frameworks are integrating themselves to cloud security. The most important decision is to adopt a framework and stick to it. The real work come after the decision when you start implementing controls. If you see areas of weakness where your particular industry is often attacked, that's where you may need to increase security above and beyond what's called for in the framework.

Use ferramentas de monitoramento para detectar atividades suspeitas e responder rapidamente a incidentes de segurança. Crie gráficos, painéis e alertas automatizados que informe a equipe sobre possíveis problemas relacionados a segurança (Conexões suspeitas, autenticações, alterações em registros, etc).

As estruturas estão se integrando à segurança na nuvem. A decisão mais importante é adoptar um quadro e mantê-lo. O verdadeiro trabalho vem depois da decisão, quando você começa a implementar controles. Se você vê áreas de fraqueza onde seu setor específico é frequentemente atacado, é aí que você pode precisar aumentar a segurança acima e além do que é exigido na estrutura.

Estabeleça métricas de desempenho de segurança na nuvem e implemente sistemas de monitoramento contínuo para identificar e responder a possíveis ameaças em tempo real. Utilize ferramentas de monitoramento de segurança na nuvem e sistemas de detecção de intrusão (IDS) e prevenção (IPS). Establish metrics for cloud security performance and implement continuous monitoring systems to identify and respond to potential threats in real-time. Utilize cloud security monitoring tools and intrusion detection (IDS) and prevention (IPS) systems.

In my experience, integrating cloud security in an orgs framework is not a set it and forget it deployment. Continuous review is needed to establish the current and desired security posture which helps in designing policies and procedures.

Realize revisões regulares das práticas de segurança na nuvem para identificar áreas de melhoria e garantir que as políticas e controles estejam atualizados com as últimas ameaças e vulnerabilidades. Isso pode incluir testes de penetração regulares, avaliações de risco e auditorias de segurança. Conduct regular reviews of cloud security practices to identify areas for improvement and ensure that policies and controls are updated with the latest threats and vulnerabilities. This may include regular penetration testing, risk assessments, and security audits.

Após a migração para a nuvem, é essencial revisar regularmente as práticas de segurança. Exemplificando, uma empresa de tecnologia identifica uma lacuna nas permissões de acesso durante uma auditoria. Eles ajustam imediatamente as configurações e reforçam a segurança com autenticação multifatorial. Utilizando dados das auditorias, a empresa atualiza suas políticas de segurança na nuvem. Revisões contínuas garantem conformidade e proteção eficaz dos dados na nuvem.

Don't just review, test. The EU is legislating for this e.g. DORA's mandatory pentesting. However you should do it regardless of legislation.

Realize revisões periódicas de sua estrutura de segurança na nuvem, identificando lacunas e áreas de melhoria. Implemente ações corretivas e preventivas e mantenha suas políticas e procedimentos atualizados.

One of the activity to be performed while integrating cloud security with existing frameworks would be map existing frameworks identify any cloud security controls that should be implemented. The implementation of new controls be based on the risk prioritisation. Most frameworks do provide official mapping to some if not all cloud security frameworks. This would significantly reduce the time and resources required.

Start by assessing your current security policies and controls against cloud security standards (e.g., CSA, NIST). Update your risk assessment processes to include cloud-specific risks. Align cloud security controls with your framework, incorporating cloud access security brokers (CASBs), identity and access management (IAM), and encryption for data at rest and in transit. Implement automated security monitoring and compliance tools suited for cloud environments. Train staff on cloud security best practices and consider adopting a DevSecOps approach to ensure continuous integration of security into all phases of development and operations.

Integrating cloud security into existing frameworks means aligning your security measures with the unique aspects of cloud computing. Start by evaluating your current security setup to identify gaps. Align your cloud security efforts with established best practices and standards, like those from the Cloud Security Alliance or NIST. Educate your team on cloud security essentials and choose cloud providers that complement your security needs. Regularly update your policies to keep pace with the evolving cloud landscape. It's about blending traditional security approaches with cloud-specific strategies to fortify your defense

One consideration when using a combination of cloud and on-site infrastructures is understanding the 'boundary of responsibility' over the management, etc., of the cloud component. For example, who is responsible for applying/ managing patching, updating, monitoring operations, maintaining backups, disaster recovery/ restoration processes, etc. Having a clear understanding of ownership (and accountability) in these areas will enable a more solid. cohesive response to be developed and applied. It will also help to ensure if the cloud infrastructure is compromised, in some way, the relevant organisation IT staff can be notified and appropriate steps, notifications, etc., be undertaken quickly and efficiently.

Training and awareness should be another key factor. By educating employees about cloud security best practices and policies will strengthen they security posture as it would be placing focus on the "human factor". Historically people have been the weakest link in security.
