Cloud Security and Storage Risks

Cloud Security Challenges

• Virtualization and cloud computing increase efficiency by decoupling IT infrastructure but adds security risks, especially for SaaS providers.
• Loss of control over assets requires reassessing security models.
• Enterprise security depends on the weakest link, making trust in service providers critical.
• Public clouds involve loss of control over physical security and resource sharing, increasing the risk of government asset seizure if another company violates the law.

Cloud Storage and Data Security

• Cloud storage services may be incompatible between vendors, which complicates data migration.
• Providers create "sticky services" that lock users into their platforms, which limits flexibility and interoperability.
• Controlling encryption keys is crucial in the cloud where customers should ensure data is encrypted during transmission and when at rest.
• Maintain security by retaining control of encryption and decryption keys rather than relying on the cloud vendor, ideally using SSL.
• Data integrity ensures data remains consistent and correct during transfer, storage, or retrieval, changing only through authorized transactions.
• A standard for guaranteeing data integrity in the cloud has not been established.
• While SaaS reduces the need for software development, using internally developed code in the cloud requires a secure SDLC.
• Mashup technology can introduce security vulnerabilities, which means development tools need built-in security models and enforced data access restrictions.

Compliance and Rapid Evolution

• SaaS providers must offer real-time log data for administrators and customers as mission-critical processes move to the cloud.
• Monitoring security and compliance is challenging due to internal and inaccessible logs where customers should negotiate log access in service agreements to meet compliance requirements.
• Cloud applications evolve rapidly, requiring users to stay updated for security.
• Frequent changes challenge traditional SDLC models, where regular upgrades are essential.

Failover and Regulatory Considerations

• Failover technology is crucial for cloud security, especially for mission-critical applications.
• Focus on protecting data at the enterprise level, not just within the cloud provider's infrastructure, as data-level security remains a key challenge.
• Current compliance standards weren't designed for cloud computing, so adaptation is needed.
• SaaS complicates compliance because it obscures data location, raising privacy, segregation, and security concerns.
• Regulations often require data separation with some countries imposing strict data residency and retention rules.

Regulatory Compliance in SaaS

• Complying with regulations like SOX, GLBA, HIPAA, and PCI DSS is more challenging in a SaaS environment.
• Cloud computing does not remove compliance responsibility but data owners remain fully accountable.
• Government policies must adapt to cloud computing opportunities and risks, mainly off-shored data and privacy protection.
• Traditional security controls like VLANs and firewalls are less effective in virtualized environments, requiring heightened attention to critical data security during the transition.

Outsourcing and Mobile Users

• Outsourcing cloud services reduces control over data, raising security concerns.
• Cost and convenience drive adoption, so security managers must work with legal teams to set up SLAs to protect corporate data.
• Cloud-based services allow mobile users to access business data without going through corporate networks, increasing security risks.
• Implement stricter security controls between mobile users and cloud services to prevent distributed cyber threats.

Virtual Machine Risks

• Cloud efficiency relies on co-locating VMs from multiple organizations on shared physical resources, which increases risks because traditional data center security can't prevent attacks between VMs.
• Internet-based administrative access further heightens exposure.
• The dynamic nature of VMs complicates security consistency and auditability.
• Cloning and distribution can propagate configuration errors and vulnerabilities, making it hard to verify security and track insecure VMs.
• Intrusion detection must work at the VM level to proactively prevent attacks.

Remote Attacks and Shared Infrastructure

• Cloud environments use standard operating systems and applications, which makes them vulnerable to remote attacks.
• VMs moving between private and public clouds face greater risks, with shared environments presenting a larger attack surface.
• Cloud computing relies on shared physical infrastructure, so security integrity monitoring is required.
• Enterprises, rather than the cloud vendors, are accountable for patching and maintenance.
• Not patching and maintaining can lead to unmanageable security risks.

Compliance and Cloud Adoption

• Enterprises must ensure compliance with regulations, regardless of data location.
• In cloud computing, data constantly moves between physical and virtual environments that requires auditors and security practitioners to rethink compliance strategies.
• Many corporations adopt cloud computing for cost savings without fully acknowledging security risks.
• To maintain trust zones, VMs must be self-defending and security responsibility shifts to the cloud provider.

Software-as-a-Service Security

• Future cloud computing models will likely combine SaaS, utility computing, and Web 2.0 collaboration technologies.

SaaS Security Considerations

• Inquire about specialized user access to data and about the hiring and management practices of administrators.
• Ensure the vendor undergoes external audits and/or security certifications for regulatory compliance.
• Data Location: Check provider data location control.
• Data segregation means ensuring encryption is available at all stages.
• Ensure encryption schemes are designed and tested by experienced professionals for data segregation.
• Recovery consists of finding out what will happen to data in case of a disaster.
• Check to see if complete restoration options are available along with the time to restore.
• Investigative support is making sure the vendor can investigate any inappropriate or illegal activity
• Long-term viability means checking what happens to data if the company goes out of business, including how data is returned and in what format.
• SaaS providers need to incorporate and enhance security practices and develop new ones.

Security and Governance

• A formal security charter aligns the security team's vision with organizational strategy.
• A charter creates, team ownership, role clarity, and expectations.
• Clear roles and expectations reduces confusion, lowers morale, reduces effectiveness, and weakens overall security.
• A security steering committee guides security initiatives and aligns them with business and IT strategies while a charter that defines roles and responsibilities for security functions is one of its key deliverables.
• A formal strategy ensures security operations are sustainable.
• Lack of a formal process results in unmanaged risks, governance failures, and missed business opportunities.
• Proper security governance ensures risk management, security monitoring, and application security are addressed.

Risk Management and Assessment

• Risk management identifies assets, links data to processes, assigns ownership, and maintains a repository.
• Owners protect, and custodians implement security controls.
• A formal risk assessment aligns security resources with business continuity.
• Formal risk assessments balance business needs with security requirements.
• This failure results in security audit issues, challenges, and ineffective controls.

• These images allow cloning with minimal startup time, reducing security barriers.
• Offline patching of VMs enhances security by enabling testing of updates before deployment.

Data Privacy, Governance, and Security

• Organizations must conduct risk assessments and gap analyses to maintain formal data privacy processes.
• A steering committee is essential to address privacy concerns.
• Since many security teams lack privacy training, organizations should hire or train privacy experts to meet demands.
• A formal data governance framework should be developed that will define a system of decision rights and accountability for information-related processes.
• Data governance includes inventory, classification, analysis (business intelligence), protection, privacy, retention/recovery/discovery, and destruction.
• Data-level security, the responsibility of enterprises rather than cloud providers, is the challenge in cloud computing.
• Security is enforced at the data level to ensure protection regardless of location with restrictions of data movement (e.g., keeping it within the U.S.) and the enforcing of encryption.
• Security also controls user access.

Application and Virtual Machine Security

• Application security is crucial for SaaS companies because it demands collaboration between security and development.
• Security features, coding practices, training, and testing tools must be defined and implemented throughout the development process.
• While engineering teams focus on the application and infrastructure layers, security teams provide necessary requirements.
• External penetration testers help assess security through code reviews and attack simulations.
• Securing a web is ensuring SaaS providers follow OWASP guidelines, comply with PCI DSS requirements, and secure LAMP stack components.
• Weak design, coding, and testing outcomes are a result of poor collaboration.
• In cloud environments, VMs run on virtualized servers, requiring security controls similar to data centers.

• Cloud services are transforming identity management, challenging traditional solutions where existing models may struggle with evolving trust assumptions, privacy concerns, and authentication processes.
• SaaS providers balance security and usability while adapting IAM strategies to ensure trust which a failure on that balance could hinder business and IT operations.

Change Management & Physical Security

• Although not directly a security issue, insecure changes can disruptions or data loss, security teams should collaborate with operations to review changes, establish security guidelines, and prioritize critical updates
• Clients lose direct control over physical security as moving to the cloud means datacenter is now managed by cloud providers, and security model may need adjusting.
• The high cost of securing data centers is a reason for companies to move to cloud services.

Business Continuity and Disaster Recovery

• In SaaS, service is critical, as it requires business continuity and disaster recovery.
• Virtualization helps application availability from hardware, allowing for quick migrations and reallocation.
• Code escrow strict transfer and storage control because source code for SaaS providers equals object code.
• Data Centers and physical infrastructure follow standard business continuity and disaster recovery protocols.
• BC plan includes IT and non-IT aspects, key personnel, facilities, crisis communication, and reputation management.
