Introduction

Cybersecurity is intended to help, protect your communication network and all equipment connected to it from attacks, that could disrupt operations (availability), modify information (integrity), or give away confidential information (confidentiality). The objective of cybersecurity is to provide increased levels of protection for information and physical assets from theft, corruption, misuse, or accidents while maintaining access for their intended users. There are many aspects to cybersecurity including designing secure systems, restricting access using physical and digital methods, identifying users, as well as implementing security procedures and best practice policies.
This section provides information on how and help to secure your system from a malicious cyber-attack.
For essential cybersecurity best practices, refer to Schneider Electric’s Recommended Cybersecurity Best Practices. https://www.se.com/en/download/document/7EN52-0390/

WARNING
POTENTIAL COMPROMISE OF SYSTEM AVAILABILITY, INTEGRITY, AND CONFIDENTIALITY

• Change default passwords at first use to help prevent unauthorized access to device settings, controls and information.
• Disable unused ports/services and default accounts, where possible, to minimize pathways for malicious attacks.
• Place networked devices behind multiple layers of cyber defenses (such as firewalls, network segmentation, and network intrusion detection and protection).
• Apply the latest updates and hotfixes to your Operating System and software.
• Use cybersecurity best practices (for example: least privilege, separation of duties) to help prevent unauthorized exposure, loss, modification of data and logs, interruption of services, or unintended operation.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Product Defense-in-depth

Secure Development Lifecycle

Schneider Electric use a Secure Development Lifecycle (SDL) process, a key product development-based framework that helps ensure products follow secure design processes across all lifecycle stages. The Schneider Electric SDL process complies with IEC 62443-4.1.

Security Features Provided

For the cybersecurity features provided by the Schneider Electric product, refer to the user manual. The features provide security capabilities which contribute towards protecting the product from potential security threats.

Defense-in-depth Measures Expected in User Environment

Defense-in-depth Approach

Schneider Electric recommends a defense-in-depth approach to cybersecurity for its customers. Defense-in-depth is a hybrid, multi-layered security strategy that provides holistic security throughout an industrial enterprise. The following are recommendations for a defense-in-depth approach to cybersecurity.

Cybersecurity Policy

Formulating a security plan, policies and procedures that cover risk assessment, risk mitigation and methods to recover from disaster. Developing an available and up-to-date guidance on governing the use of information and technology assets in your company.

Network Separation

Separating the industrial automation and control system from other networks by creating Demilitarized Zones (DMZ) to protect the industrial system from enterprise network requests and messages.

Perimeter Security

Using firewalls, authentication, authorizations, VPN (IPsec) and antivirus software to prevent unauthorized access. Installed devices, and devices that are not in service, are to be in an access-controlled or monitored location.

Network Segmentation

Containment of a potential security breach to the only affected segment by using switches and VLANs to divide the network into sub-networks and by restricting traffic between segments. This helps contain malware impact to one network segment; thus limiting damage to the entire network.

Device Hardening

Password management, user profile definition and deactivation of unused services to strengthen security on devices. Controls against malware – detection, prevention and recovery controls to help protect against malware are implemented and combined with appropriate user awareness.

Security Practices for Removable Devices

When using removable devices such as external hard drives or USB drives, refer to the following recommended actions to protect against unauthorized access and unintended disclosure of data.

• Scan any devices used to exchange data before using them in any node connected to the network.
• Encrypt your files.
• Use password protection.
• Do not store sensitive data in removable media, or if you need to store sensitive data in removable media, manage it properly in a secure location.

Monitoring and Update

Surveillance of operator activity and network communications. Regular updates of software and firmware.

Secure Deployment

Network

Improve security of networked devices by using multiple layers of cyber defense (such as firewalls, network segmentation, and network intrusion detection and protection). Disable unused ports/services and default accounts to help minimize pathways for malicious attackers.
To reduce the security risks associated with networks, follow these guidelines:

• Use firewalls and other security devices or settings to limit access to the host network, based on your security risk assessment.
• When using a firewall: Restrict communication to the expected ports, as per your network configuration. Only open those ports that are necessary for network communication.
• When using network switches: Close or disable unused network ports to prevent unauthorized connection of network nodes or other devices.

Patching

Be sure that all Windows updates and hotfixes, especially Windows security updates are regularly applied on the operating system.

Allow listing

Zero-day cybersecurity attacks take place before a software vendor is aware of a cybersecurity exploit. Meaning that neither software, nor anti-virus programs have been created or updated to protect against the zero-day threat or attack.
Application allow listing is recommended to protect against zero-day attacks. This specifies an index of approved software applications and processes that are permitted to be present and active on the operating system.

Secure Account Management

User Access

Cybersecurity policies that govern user accounts and access, such as least privilege and separation of duties, vary from site to site. Work with the facility IT System Administrator to ensure that user access adheres to the site-specific cybersecurity policies.

Account Management

Windows-based products require the sign-in password to be set in order to reduce the risks of unauthorized access, intrusion and infection of malicious software.
NOTE: In order to build and operate a secure system, we strongly recommend that you use a different authority account in each phase as follows.

Use the product in an environment that takes into account the above items to reduce security risks.

Secure Maintenance

Software Update

Maintain up-to-date version of any software related to the product, such as security updates, drivers, utilities, configuration tools.
For the latest version of the software we provide, refer to the following URL. www.se.com

Network Monitoring

When using a firewall:

• Periodically monitor the firewall to ensure the configuration has not been changed, and that the firewall status does not indicate communication has occurred on unexpected ports.

• Only open those ports that are necessary for network communication.
  When using network switches:

• Periodically monitor the switch to ensure the configuration has not been changed, and that the switch status does not indicate communication has occurred on unexpected ports.

Monitoring Operating System

Install operating system patches and anti-virus software updates on the product, as they are released.
Periodically monitor the Windows accounts available on the product to ensure that only the necessary personnel can log on to the product, with the appropriate level of access. Remove inactive or unnecessary user accounts.
Review the Windows System Events Log to monitor logon and logoff activity, and to detect attempted unauthorized activity.
Periodically review user accounts and their roles and privileges to ensure compliance with your organization’s policy.

Maintaining Current Backups

The most effective way to recover from a malware attack, unauthorized access or unintended data exposure is backing up your systems and data regularly and store it in a secure, separate, non-shared location.
Back up all critical resources off the network and keep a copy in a secure, tamperproof, or offline environment.
