- Update Remote Support Tools: Ensure that the remote support software is always running the latest version.
Regular updates close security gaps that could be exploited by attackers.
Employee Training and Awareness
Human error remains one of the leading causes of security breaches. Training employees to recognize and respond appropriately to security threats is essential.
Training Topics
- Phishing Awareness: Teach employees how to identify and report suspicious emails or requests.
- Safe Use of Remote Support Tools: Explain the proper procedures for initiating and authorizing remote support sessions.
- Recognizing Social Engineering: Educate on tactics used by attackers to manipulate individuals into divulging confidential information.
- Reporting Procedures: Clearly outline how to report potential security incidents or suspicious activities.
An informed workforce is a critical line of defense against cyber threats.
Monitor and Log Remote Access Activities
Monitoring remote support sessions can help detect unauthorized activities and provide valuable insights for security audits.
Actionable Steps
- Implement Comprehensive Logging: Record details of all remote access sessions, including user identities, time stamps, and actions performed.
- Real-Time Monitoring: Utilize security tools that offer real-time alerts for unusual or unauthorized activities.
- Regular Review of Logs: Schedule periodic audits of logs to identify patterns or anomalies that may indicate security issues.
- Separation of Duties: Ensure that no single individual has control over all aspects of monitoring and logging to prevent internal abuse.
Effective monitoring helps in early detection and response to security incidents.
Use Virtual Private Networks (VPNs)
VPNs encrypt network traffic, providing a secure tunnel for data transmission between remote users and corporate networks.
Actionable Steps
- Mandatory VPN Use: Require all remote connections to pass through a company-approved VPN.
- Select Secure VPN Protocols: Use VPN solutions that support secure protocols like OpenVPN or IKEv2.
- Implement Client Authentication: Use certificates or MFA for VPN authentication to enhance security.
- Regularly Update VPN Software: Keep the VPN infrastructure up to date to protect against known vulnerabilities.
VPNs protect data integrity and confidentiality during remote access sessions.
Secure Endpoint Devices
The security of remote support is only as strong as the devices used by employees.
Actionable Steps
- Enforce Device Security Policies: Require antivirus software, firewalls, and regular updates on all devices.
- Use Endpoint Protection Platforms (EPP): Implement advanced security solutions that provide real-time threat detection and response.
- Encrypt Sensitive Data: Use full-disk encryption on devices accessing corporate data.
- Restrict Access on Personal Devices: If BYOD is allowed, implement mobile device management (MDM) solutions to enforce security policies.
- Regular Security Assessments: Conduct vulnerability scans and security assessments of endpoint devices.
Securing endpoint devices reduces the attack surface available to cybercriminals.
