Why Data Center Compliance Is Critical For Business Security

Data center security compliance can reasonably be viewed as a defensive measure to protect businesses from regulatory sanctions. The importance of compliance is, however, far greater than that. Compliance actually plays a key role in ensuring business security. Here is what you need to know.

The basics of data center security compliance

Data center security compliance is essentially the practice of demonstrating that data centers manage their data responsibly. This means implementing measures to ensure the security (and hence privacy) of sensitive data.

Compliance requirements are set down by industry bodies and/or local governments. This means that determining which compliance standards apply to which data requires an understanding of both the data and its source.

The importance of compliance for security

The compliance process is intended to provide proof that an organization has implemented an appropriate level of security. This means that the importance of compliance for security is that it enforces a consistent, minimum security standard on all organizations under its remit. Moreover, it sets out a framework and process for achieving that standard.

Key compliance standards for data centers

Here are the five main data center security compliance standards currently in effect.

Payment Card Industry Data Security Standard (PCI-DSS): PCI-DSS applies to organizations that handle payment card transactions. Compliance ensures that data centers implement measures to protect cardholder information from fraud and data breaches.

Health Insurance Portability and Accountability Act (HIPAA): HIPAA sets strict guidelines for the storage, processing, and transmission of healthcare data in the United States. Data centers supporting healthcare clients need HIPAA compliance to secure protected health information (PHI) against unauthorized access.

SOC 2 (Service Organization Control 2): SOC 2 is a U.S.-based compliance standard focused on the secure handling of customer data by service providers. It examines data center practices in security, availability, processing integrity, confidentiality, and privacy.

Federal Risk and Authorization Management Program (FedRAMP): FedRAMP is a U.S. government program that sets security standards for cloud service providers working with federal agencies. Data centers that seek to host federal data must comply with FedRAMP to ensure high levels of data protection and operational security for government information.

General Data Protection Regulation (GDPR): GDPR is a comprehensive regulation that governs data protection and privacy for residents of the European Union regardless of their nationality. Organizations outside the EU must agree to comply with GDPR before they can handle data belonging to EU residents even if they are nationals of another country.

Common factors in compliance standards

Although data center security compliance standards all set their own rules, they also all tend to have very similar requirements. This means that measures to comply with one standard will often ensure (or help to ensure) compliance with another. Here are five common factors that apply to most, if not all data center security compliance standards.

Data encryption: Many compliance standards require encryption for both data at rest and data in transit. This ensures that even if data is intercepted or accessed without authorization, it remains unreadable without the proper decryption keys.

Access controls: Limiting who can access sensitive data is critical. Compliance standards often mandate role-based access controls, multi-factor authentication, and regular reviews of access permissions to reduce the risk of unauthorized access.

Physical security: Protecting the physical infrastructure of data centers is essential. Standards typically require security measures like surveillance, secure access points, and environmental controls to prevent unauthorized physical access and damage.

Audit and logging: Compliance frameworks emphasize the importance of logging access and activity within systems. These logs provide a record of actions taken, which is essential for auditing, detecting security incidents, and investigating potential breaches.

Incident response: Having a clear plan for responding to security incidents is crucial. Compliance standards often require that data centers have documented procedures for detecting, reporting, and mitigating incidents to minimize potential damage and ensure accountability.

Challenges in achieving compliance

Achieving compliance with any standard can be challenging for organizations. Here are three of the most common issues that can derail progress towards compliance and how to deal with them.

Complex regulatory requirements: Different standards often have overlapping or conflicting requirements, making compliance challenging. To address this, conduct a comprehensive compliance assessment to identify overlapping controls and streamline efforts. Also, consider adopting a unified compliance framework to cover multiple standards.

High costs of compliance: Implementing necessary security controls, audits, and training can be costly, especially for smaller organizations. To address this, prioritize compliance spending by focusing on high-risk areas first. Using automation tools and third-party compliance-as-a-service providers can also reduce costs and streamline processes.

Evolving threat landscape: New security threats and evolving regulations mean that compliance is an ongoing challenge. To address this, regularly update security policies and conduct training to stay informed about new risks. Implementing continuous monitoring tools helps detect and respond to emerging threats, ensuring the data center remains compliant.
