Protecting Your Legal Practice: Essential Cybersecurity Tips for Law Firms


As legal professionals increasingly rely on Office 365, prioritising cybersecurity becomes crucial to safeguard your legal practice. Let’s explore essential tips to protect your firm from cyber threats:

Enable Multi-Factor Authentication (MFA)

  • Why? MFA adds an extra layer of security by requiring users to provide multiple forms of identification before accessing their accounts.
    • How?
      • Enable MFA for all admin and user accounts within Office 365.
      • Configure verification options such as SMS, phone call, or mobile app.
      • Communicate MFA requirements and provide user support.
      • Enforce MFA policies rigorously: Ensure that MFA is mandatory, preventing any non-compliance. Users cannot connect to Office 365 without MFA enabled. New users should be automatically configured to require MFA, and if anyone disables MFA (deliberately or accidentally), they must re-enable it to regain access.
      • Offer ongoing training to educate users on the importance of MFA.

Regularly Update and Patch

  • Why? Regular updates and patches address security vulnerabilities and protect against known threats.
    •  Configure Office 365 for automatic updates from Microsoft.
    • Implement update rings to test updates on a subset of users before rolling out to everyone.
    • Ensure critical and important security updates are applied within two weeks to meet compliance requirements.

Educate Staff on Phishing Awareness

  • Why? Phishing attacks are common entry points for cybercriminals.
    • How?
      • Train staff to recognise phishing email red flags.
      • Teach them to avoid suspicious links and verify requests.
      • Establish clear reporting procedures.
      • Conduct simulated phishing exercises and provide ongoing training.

Secure Mobile Devices

  • Why? Mobile devices are vulnerable targets for cyberattacks.
    • How?
      • Centrally manage and secure devices with Mobile Device Management (MDM).
      • Require strong authentication for device access.
      • Encrypt data stored on devices.
      • Control mobile app usage with Mobile Application Management (MAM).

Data Encryption

  • Why? Encrypt sensitive data to prevent unauthorised access.
    • How?
      • Activate encryption features within Office 365.
      • Use Transport Layer Security (TLS) for secure email communication.
      • Apply Rights Management Services (RMS) for document encryption.
      • Implement Data Loss Prevention (DLP) policies.
      • Manage encryption keys and educate staff on encryption protocols.

Role-Based Access Control (RBAC)

  • Why? Limit access to critical data based on job roles.
    • How?
      • Define different job roles (attorneys, paralegals, etc.).
      •  Determine specific permissions for each role based on the principle of “least privilege”: Ensure users are granted the minimum permissions necessary to perform their job functions.
      • Group users with similar roles.
      • Assign roles and permissions.
      • Regularly review and update role assignments.

Backup Firm Data

  • Why? Regular backups ensure data recovery in case of cyber incidents.
    • How?
      • Prioritise critical data.
      • Choose secure backup solutions (servers or cloud-based).
      • Schedule regular automated backups with versioning.
      • Encrypt backup data and test recovery processes.

Monitor User Activity

  • Why? Detect and respond to suspicious behaviour promptly.
    • How?
      • Enable audit logging for relevant activities.
      • Use a Security Information and Event Management (SIEM) system to automate the review of logs to detect unusual patterns and behaviours.
      • Set up alerts and investigate incidents.
      • Continuously improve monitoring capabilities.

Incident Response Plan

  • Why? Be prepared for cyber incidents.
    • How?
      • Conduct risk assessment.
      • Collaborate to develop a comprehensive incident response plan.
      • Ensure readiness by having the right people and technology available to respond effectively.
      • Train staff, test procedures, and adapt based on real-world incidents.

Cyber Insurance

  • Why?  Cyber insurance provides comprehensive support in the event of data breaches or cyber-attacks, including financial protection, PR management, specialist cyber forensic investigation, ransom payment (where appropriate), expert advice on regulatory notifications, and reimbursement for costs related to incident recovery, such as IT system rebuilding.
    • How?
      • Assess needs and research specialised insurers.
      • Evaluate policies and consult experts.
      • Integrate with broader security strategy and update coverage.
