What is the ISO 27001 Remote Working Policy?

ISO 27001 is a globally recognized standard for Information Security Management Systems (ISMS). Its purpose is to provide a structured framework to manage and protect sensitive information.

With the rise of remote work, organizations are expanding beyond office walls, making secure access and data protection a critical challenge. Remote work increases the attack surface because employees often use personal devices, home networks, and third-party cloud services.

An ISO 27001 remote working policy is a formalized set of guidelines that defines how employees should access, handle, and protect organizational information when working outside traditional office settings.

Key aspects include:

• Scope: Identifies which employees, devices, and data are covered.
• Roles & Responsibilities: Defines responsibilities of employees, IT teams, and management.
• Security Controls: Specifies technical and operational measures to prevent data breaches.

An ISO 27001-compliant policy may mandate that all remote workers use company-managed devices with VPN and endpoint protection , while restricting access to sensitive financial or personal data only to authorized personnel.

ISO 27001 Remote Work Policy Objectives

The ISO 27001 remote working policy aims to balance operational flexibility with strong cybersecurity, focusing on the CIA triad — Confidentiality, Integrity, and Availability — while supporting broader organizational goals.

Primary Objectives: CIA Triad

Confidentiality: Protects sensitive data from unauthorized access. Remote employees must use secure devices, VPNs, and encrypted channels to prevent data leaks.

A financial analyst accesses client data through a company VPN with encryption, ensuring only authorized personnel can view it.

Integrity: Ensures data is accurate and tamper-proof. Controls like audit trails and versioning prevent unauthorized changes.

Project updates in cloud systems are tracked, allowing quick detection of anomalies or unauthorized edits.

Availability: Guarantees access to necessary resources. Redundant systems, backups, and business continuity measures maintain workflow during outages.

Customer support teams maintain access to ticketing systems even if a home network fails, using cloud redundancies.

Secondary Objectives

• Employee accountability and awareness: Training and clear responsibilities encourage secure behaviors.
• Reduced exposure to cyber threats: Risk-based controls and monitoring prevent breaches.
• Compliance alignment: Policies ensure adherence to laws and corporate governance, such as GDPR or HIPAA.

These objectives ensure sensitive information stays secure, systems remain reliable, and employees act responsibly, enabling safe and compliant remote work.

How to Perform Remote Work Risk Assessment

A thorough risk assessment is the cornerstone of any ISO 27001-compliant remote working policy. It identifies vulnerabilities, evaluates potential threats, and guides the implementation of security controls, ensuring that remote work does not compromise organizational assets.

By following a structured approach, organizations can proactively manage risks rather than reacting to incidents.

1. Asset Identification

The first step is to catalog all assets used in remote work. This includes:

• Devices: Laptops, desktops, smartphones, tablets, and personal devices used for business purposes.
• Software: Collaboration tools, cloud applications, VPNs, and internal systems.
• Data: Confidential business information, customer records, financial reports, and intellectual property.

**Practical Tip: **Create an inventory list and classify assets by sensitivity and business criticality. This helps prioritize protection measures for high-risk assets.

2. Threat Analysis

Once assets are identified, assess potential threats that could compromise their security. Common remote work threats include:

• Phishing attacks: Employees may receive fraudulent emails attempting to steal credentials.
• Malware and ransomware: Devices connected to unsecured networks may be infected.
• Device theft or loss: Laptops or mobile devices may be lost or stolen outside the office.
• Human error: Accidental data deletion, misconfigured cloud storage, or unauthorized file sharing.

3. Risk Evaluation

Evaluate the likelihood and potential impact of each identified threat. This step helps prioritize which risks require immediate mitigation. Consider:

• Probability: How likely is the threat to occur?
• Impact: How severe would the consequences be if it happens?
• Criticality: How essential is the affected asset to business operations?

**Practical Tip: **Use a risk matrix to score each threat from low to high based on probability and impact, guiding decision-making for controls.

4. Control Implementation

After identifying and evaluating risks, implement appropriate security controls. ISO 27001 recommends a combination of preventive, detective, and corrective measures :

• Preventive controls: VPNs, multi-factor authentication (MFA), strong password policies, device encryption, and secure cloud access.
• Detective controls: Intrusion detection systems (IDS), monitoring remote access logs, and automated alerts for unusual activity.
• Corrective controls: Backup and recovery procedures, incident response plans, and rapid remediation protocols.

A company with remote financial staff may deploy MFA for system access, enforce encrypted storage, and maintain regular device audits, significantly reducing the risk of unauthorized access or data leaks.

5. Monitoring & Review

Risk management is continuous, not a one-time task. Regular monitoring and reviews ensure that implemented controls remain effective and adapt to evolving threats:

• Conduct periodic audits of remote devices and access logs.
• Update policies as new threats or technologies emerge.
• Review employee adherence to security protocols and provide additional training if necessary.

Quarterly audits may reveal that some remote employees are bypassing VPNs, prompting policy reinforcement and additional technical safeguards.

Best Practices for Managing Remote Work Security

A proactive approach helps organizations reduce vulnerabilities and strengthen compliance with ISO 27001 standards.

Employee Training and Awareness

Employees are the first line of defense against cyber threats. Regular training is essential to ensure they understand safe remote work practices.

Running simulated phishing campaigns helps employees recognize and avoid suspicious emails, while training on secure file sharing and password hygiene reinforces critical cyber hygiene practices.

Encouraging employees to report unusual or suspicious activity builds a culture of vigilance and accountability.

For instance, if a staff member receives a potentially malicious link while working from home, prompt reporting allows IT teams to respond quickly and prevent a wider breach.

Technology Solutions

Technology plays a critical role in safeguarding remote operations. Organizations should deploy Endpoint Detection and Response (EDR) tools to continuously monitor devices for signs of compromise.

Secure Access Service Edge (SASE) solutions unify network and security functions, ensuring consistent protection across all remote connections.

Additionally, cloud access security brokers (CASB) provide visibility and control over cloud applications, helping prevent data leakage and unauthorized access.

Combining these tools ensures that technical safeguards align with organizational policies and ISO 27001 controls.

Monitoring and Auditing

Continuous oversight is vital for maintaining secure remote work environments. Conducting monthly audits of remote access logs can identify unusual behavior, such as logins from unexpected locations or devices.

Dashboards that track anomalies help IT teams proactively respond to threats, while audit findings inform updates to security policies and procedures.

By regularly reviewing system activity and adjusting controls based on insights, organizations can stay ahead of emerging risks and maintain compliance with ISO 27001 standards.
