Security controls can help organizations reduce exposure and establish more consistent information-protection practices.

Business Data Security vs. Cybersecurity

Cybersecurity is a broad discipline covering systems, networks, applications, devices, identities, and information.

Data security focuses more specifically on protecting information throughout its lifecycle.

A simplified data-security lifecycle can be represented as:

Collect → Classify → Store → Access → Use → Share → Retain → Securely Dispose

Each stage can require different controls.

Data Classification

Data classification helps organizations determine how information should be handled according to its sensitivity.

A basic classification model might include:

Organizations can use classification to guide access permissions, encryption, retention, monitoring, and sharing requirements.

Information Inventory

Organizations should understand what important information they have and where it exists.

A data inventory may identify:

• Information type

• Business owner

• Storage location

• Applications

• Users

• Third-party processors

• Geographic location

• Retention period

• Security classification

• Backup arrangements

An inventory can help security teams identify systems containing sensitive information and determine where additional controls may be appropriate.

Access Controls

Access controls determine who can access information and which actions they can perform.

Organizations may use:

• Role-based access control

• Least-privilege permissions

• Multi-factor authentication

• Single sign-on

• Privileged access management

• Conditional access

• Periodic access reviews

Permissions should generally reflect legitimate business responsibilities.

Access should also be reviewed when employees change roles or leave an organization.

Authentication and Identity Security

Strong authentication helps protect business information from unauthorized account access.

Common controls include:

• Multi-factor authentication

• Passkeys

• Security keys

• Strong credential management

• Single sign-on

• Conditional access

• Privileged-account protection

Administrative accounts should generally receive additional safeguards because they may provide access to large amounts of business information.

Encryption

Encryption can help protect information when it is stored or transmitted.

Organizations may consider:

• Encryption at rest

• Encryption in transit

• Key management

• Certificate management

• Encrypted backups

• Secure communication protocols

Encryption should be implemented according to the organization's data sensitivity, architecture, technology environment, and applicable requirements.

Data Loss Prevention

Data-loss prevention technologies and processes can help organizations identify and control inappropriate movement of sensitive information.

Potential controls can monitor:

• Email

• Cloud storage

• Endpoints

• File transfers

• External devices

• Applications

• Collaboration platforms

Rules can be configured to identify certain types of sensitive information and trigger alerts or other controls where appropriate.

Endpoint and Device Security

Business information can be exposed through laptops, mobile devices, workstations, servers, and other endpoints.

Endpoint security can include:

• Device encryption

• Endpoint protection

• Patch management

• Secure configuration

• Device authentication

• Mobile-device management

• Remote-wipe capabilities where appropriate

• Security monitoring

Organizations should establish procedures for lost, stolen, or compromised devices.

Network and Application Security

Data-security programs can also incorporate network and application controls.

Examples include:

• Firewalls

• Network segmentation

• Secure remote access

• Application authentication

• API security

• Vulnerability management

• Secure software development

• Web-application protection

• Network monitoring

Security should be considered throughout the technology lifecycle rather than only after systems are deployed.

Cloud Data Security

Cloud environments can contain significant amounts of business information.

Cloud data-security considerations may include:

• Storage permissions

• Encryption

• Identity management

• Configuration controls

• Logging

• Backup

• Data location

• Third-party access

• Application security

• Data deletion

Organizations should understand the security responsibilities shared between cloud providers and customers.

Backup and Recovery

Backups can help organizations recover information following system failures, accidental deletion, ransomware, or other disruptive events.

Backup planning can include:

• Backup frequency

• Recovery objectives

• Backup encryption

• Access controls

• Offline or isolated copies where appropriate

• Geographic redundancy

• Restoration testing

• Backup monitoring

A backup strategy should be tested because having a backup does not necessarily mean that information can be successfully restored.

Data Retention and Secure Disposal

Organizations should establish retention requirements for important business information.

Retention decisions may consider:

• Business needs

• Regulatory requirements

• Contracts

• Tax and accounting obligations

• Litigation requirements

• Industry standards

• Privacy requirements

When information is no longer required and no retention obligation applies, organizations may use secure disposal procedures.

Secure disposal can involve:

• Verified deletion

• Media destruction

• Device sanitization

• Secure document destruction

• Account deactivation

Third-Party Data Security

Businesses frequently share information with technology providers, consultants, vendors, contractors, and other third parties.

Third-party security reviews may consider:

• Security controls

• Data access

• Encryption

• Incident notification

• Subprocessors

• Compliance reports

• Access restrictions

• Data retention

• Contractual security requirements

• Offboarding procedures

Vendor access should be limited to legitimate business requirements.

Security Monitoring and Logging

Security monitoring can help organizations detect unusual activity involving business information.

Monitoring may include:

• Authentication events

• Data-access activity

• Privileged actions

• File activity

• Network traffic

• Configuration changes

• Security alerts

• Administrative activity

Logs can support security investigations, compliance reviews, and incident response.

Organizations should establish appropriate log-retention and protection practices.

Data Breach and Incident Response

A data-security incident can involve unauthorized access, disclosure, alteration, loss, or destruction of information.

A response process may follow:

Detect → Assess → Contain → Investigate → Recover → Notify Where Required → Review

Organizations can establish:

• Incident categories

• Escalation procedures

• Response teams

• Evidence-preservation procedures

• Communication processes

• Regulatory notification procedures

• Recovery steps

• Post-incident reviews

Notification requirements depend on the information involved, jurisdiction, organization, and circumstances.

Compliance and Regulatory Requirements

Business data may be subject to different regulatory and contractual requirements.

Depending on the organization, relevant requirements can involve:

• Data-protection laws

• Financial information

• Healthcare information

• Payment-card information

• Employee records

• Consumer information

• Government contracts

• Industry-specific requirements

Organizations should identify which requirements apply to their specific data and operations.

Security frameworks can help organize controls but do not automatically establish compliance with every law.

Common Security Frameworks and Standards

Organizations may use recognized frameworks and standards to structure data-security programs.

Examples include:

• NIST Cybersecurity Framework

• NIST security and privacy guidance

• ISO/IEC 27001

• CIS Controls

• SOC 2

• PCI DSS

• Industry-specific security requirements

The appropriate framework depends on business activities, customers, information types, contractual obligations, and regulatory requirements.

Security Policies and Governance

A data-security policy framework can define organizational requirements for handling information.

Policies may address:

• Data classification

• Access management

• Encryption

• Passwords and authentication

• Remote access

• Device security

• Cloud storage

• Data sharing

• Retention

• Secure disposal

• Incident response

• Vendor security

Policies should be supported by procedures, training, technical controls, and monitoring.

Employee Data-Security Awareness

Employees interact with business information every day.

Security-awareness programs can address:

• Phishing

• Social engineering

• Password protection

• Multi-factor authentication

• Secure file sharing

• Data classification

• Device security

• Remote work

• Incident reporting

Training should reflect the employee's responsibilities and the types of information they handle.
