How to Securely Integrate Xerox Printers into Your IT Security Strategy

Fundamentals and Principles of Printer Security

Modern printers and copiers are technically fully functional computers with an IP address, memory, operating system, and access to sensitive information. They process not only print jobs, but also scans and faxes, and often store this data temporarily on internal hard drives or SSDs. If their security is neglected, they become potential entry points into the network.

The most common printer vulnerabilities include unprotected network interfaces, outdated firmware, open ports, poor authentication, unencrypted data transmission, and insecure configurations. Cybercriminals specifically exploit these vulnerabilities to infiltrate networks or install malware.

The relevance ofGDPRshould not be underestimated here. Every device that processes or stores personal data falls under the GDPR. The General Data Protection Regulation requires technical and organizational measures to protect this data. These include encryption, access control, and secure disposal. If these aspects are disregarded, even simple printouts canGDPR violationrepresent.

Xerox recognized these developments early on and developed a comprehensive, multi-layered security approach that protects all parts of the data chain: printing, copying, scanning, faxing, file downloads, and system software. This approach is based on four key aspects:Prevention, Detection, Protection and External Partnerships

Preparation: Required safety measures and functions

Before going into detail, it is important to understand and prepare the fundamental security precautions that are essential for integrating your Xerox printers into your IT security strategy:

•Secure device configuration:Many network printers are shipped with factory default passwords. This is a cardinal sin from an IT security perspective. Change them.Default passwords immediatelyand use complex passwords. Additionally, disable all unused ports and services on the device. Configure secure WLAN and network settings.

•Regular firmware and software updates:Outdated firmware is a common and often underestimated risk factor. Security vulnerabilities that have already been patched by the manufacturer remain open on unpatched devices and can be exploited. Aintegrated patch management for printersshould therefore be an integral part of every IT security strategy in order to install security updates in a timely manner.

•Network segmentationPrinters should not be integrated indiscriminately into the main network. It is crucial to connect them viaclearly defined security zones (e.g., VLANs)to disconnect from the rest of the network. This reduces the attack surface and strengthens overall network security. Additionally, restrict access via firewalls to specific servers or user groups.

•Access Controls and Authentication:Ensure that only authorized personnel have access to the devices and their functions. This can be achieved through user authentication using usernames/passwords, cards (RFID, smart cards), or mobile authentication methods such as NFC/QR codes. Implement role-based access control so that each team member can only use the functions authorized to them.

•Data encryption:Ensure that sensitive data is transmitted encrypted, for example through protocols such as IPsec or SSL/TLS for network connections. Data stored on the device should also be encrypted.

•Secure data deletion:Many modern printers temporarily store documents on internal storage media. Without encryption and automated deletion routines, this data remains in the device for a long period and can potentially be read out. Enable automatic data deletion after each print job and use certified data wiping software before selling or the end of a lease.

•Employee AwarenessTechnical measures are only as effective as employee behavior. Inconsiderate behavior, such as leaving sensitive printouts lying around or using unsecured Wi-Fi functions, can undermine any security measure. Targeted training, awareness campaigns, and clear guidelines are therefore essential to sustainably establish a secure printing environment.

•Monitoring and Logging:Monitor and log printing and copying processes to detect potential security breaches early. Analyze log data to identify suspicious activities.

Detailed Methods & Solutions with Xerox

Xerox offers a comprehensive suite of security features that go beyond basic measures and provide deep integration into yourIT Security Strategyenable.

- Prevention: Prevent access from the outset

The first and most obvious vulnerability is physical access to the printer and its functions. Xerox's security measures begin withPrevention of attacks through user authentication.

•Strong authentication:Xerox printers support various authentication methods to ensure that only authorized persons have access to the devices. These include the verification of usernames and passwords (locally or on the network), card-based authentication (magnetic stripe, RFID, or smart cards), and cloud-based authentication via theXerox® Workplace Cloudor external identity providers (IdPs). The support ofMulti-Factor Authenticationprovides an additional layer of security.

•Role-Based Access ControlAfter logging in, role-based access control ensures that each team member can only see and use the features you have approved.

•Comprehensive logging:Every action of every user is logged, ensuring a complete audit trail. This helps you track who used which features and when.

•System Software Integrity:Xerox system software is digitally signed. Any attempt to install an infected, unsigned version is automatically rejected. Encrypted keys are stored onTPM chips(Trusted Platform Module) to protect printers against cyberattacks.

– Detection: Identify threats early

Should the preventive measures be overcome, the rapid detection of security breaches is crucial to minimize the damage.

•Firmware Verification:TheXerox® ConnectKey® Technologyperforms a comprehensive firmware verification test, either at system startup or on demand. This alerts you if malicious changes to your printer are detected.

•Malware protection with allowlisting:Xerox integrated solutions use theTrellix Allowlisting Technology(formerly McAfee) to continuously scan the system for malware and automatically prevent malware execution.

•Integration in SIEM Systems:Xerox devices can be integrated into market-leadingSIEM Software Tools (Security Information and Event Management)how to integrate Trellix Enterprise Security Manager, LogRhythm, and Splunk. This enables real-time communication of security event data, which helps in the early detection of security breaches and prevents or mitigates potential damage to the enterprise from security threats.

•Network Integration with Cisco ISE:The integration with theCisco® Identity Services Engine (ISE)allows Xerox devices to be discovered on the network and classified as printers, which facilitates the implementation of security policies and compliance requirements.

•Configuration Watchdog:This function monitors up to 75 security settings. If unauthorized changes are detected, these settings are automatically reverted, saving IT staff time and ensuring compliance with security regulations.

– Protection: Secure data and documents

Xerox offers comprehensive solutions to protect both printed and scanned documents from unauthorized disclosure or alteration.

•Secure Printing (Follow-Me-Printing):With aPIN Codeor a card-based release system ensures that print jobs are only output directly at the device after successful authentication by the user. This prevents confidential documents from being left unattended in the output tray.

•Security of scanned informationUnauthorized access to scan information is restricted by digitally signed, encrypted, and password-protected file formats. On ConnectKey printers, the „To/Cc/Bcc“ email fields can also be locked to restrict the scan destination to internal addresses.

•Encryption of stored data:Stored information is processed with a256-bit encryptionprotected at the highest level.

•Secure Data SanitizationNo longer required data that has been processed or stored on the device is deleted using data sanitization and data deletion algorithms that comply with the strict specifications of the US National Institute of Standards and Technology (NIST) and the US Department of Defense.

•Xerox Workplace Suite & Cloud:These solutions provide additional protection and generate notifications and reports on data usage.

– Automation and Management: Efficiency in Security

Xerox IT Securityis not only robust, but also easy to implement and manage.

•Predefined security profilesYou can choose one of the predefined security profiles (Standard, Enhanced, or High), and the printer will automatically configure the appropriate security settings.

•Fleet Orchestrator:This function automates configuration and firmware updates in smaller printer networks.

•Xerox Printer Security Audit Service:This service optimizes device management by automating policy compliance and displaying data in a clear dashboard.

– External Partnerships: Strength through Cooperation

Xerox actively collaborates with leading security companies and certification bodies to ensure the highest security standards.

•Collaboration with industry leaders:Xerox partners with companies like Trellix and Cisco to integrate their comprehensive standards and expertise into its own offerings.

•Independent certifications:Independent third parties, such as Common Criteria (ISO/IEC 15408) and FIPS 140-2/140-3, measure Xerox's performance based on international standards and confirm high compliance levels in printer security.

•Bug Bounty ProgramThe Bug Bounty program with HackerOne is further proof of Xerox's commitment to security and provides an independent resource for technology validation.

– Network segmentation with VLANs: An essential protective layer

The isolation of printers within the network is one of the most effective measures to improve theXerox IT Security.

•Why VLANs?Printers can be a vulnerability because they often lack the same security measures as computers. VLANs (Virtual Local Area Networks) make it possible to segment devices virtually so that printers in different VLANs operate isolated from one another, even if they are located on the same physical network. This significantly limits potential attack vectors.

•Advantages:Separating printers into separate VLANs allows network traffic to be better organized and controlled. This facilitates the management of access rights and security policies and protects against internal threats by restricting printer access to selected VLANs or user groups. In addition, it helps meet compliance requirements.

•ImplementationIntegrate your Xerox printers into a separate VLAN and isolate them from the rest of the network using firewalls. Restrict access exclusively to authorized systems or users.

– Handling consumables (chips on toner cartridges): An often overlooked risk

Another aspect ofXerox IT Securityconcerns the consumables.

•Potential risks:Some alternative toner cartridges use chips whose origin, firmware, and security standards are not always transparent. When the chip communicates with the printer, there is a theoretical possibility of firmware manipulation or unauthorized data access. Manipulation or faulty communication of the chip can lead to malfunctions, firmware errors, or even security vulnerabilities in the system.

•Original Cartridges vs. Compatible CartridgesAs a rule, original cartridges are safer because they are developed and certified by the printer manufacturers, including tested chips. This significantly reduces the risk of manipulated communication or incompatible interfaces.

•Handling of alternative cartridges:Should you use compatible cartridges with a chip, a risk assessment is essential. Look for trustworthy manufacturers that provide information about their chip technology, support encryption protocols, and guarantee compatibility with current firmware versions. In security-critical environments, such as administration or healthcare, tested original products are usually the better choice. It is recommended to check firmware updates before installing alternative cartridges and, if necessary (and with caution), to disable them, as automatic updates can render third-party chips unusable or cause unintended blocks. Regular monitoring of device data is also important.

Prevention: Continuous security and avoidance of problems

Xerox IT Securityis not a one-time project, but a continuous process. To avoid problems and ensure long-term security, you should establish the following preventive measures:

•Regular safety audits:Conduct a risk analysis and security checks of your printing environment at least semi-annually. Check whether default passwords are active, which ports are open, whether the firmware is up to date, and whether sensitive printouts are left lying around unprotected. Log files can provide information about attempted attacks.

•Holistic Patch ManagementIntegrate printer firmware updates into your enterprise-wide patch management system to close security vulnerabilities immediately after they are released by the manufacturer.

•Continuous employee training:Train your employees regularly on printer security and data protection. Raise their awareness of the risks and the proper use of the devices. Clear guidelines for the secure handling of printers are essential.

•Secure disposal processes:Define clear data protection measures for the decommissioning or servicing of printers by external service providers. Ensure that all stored data is deleted or the hard drive is physically destroyed before devices leave the company.

•Review of external service providers:If you have leasing or maintenance contracts with external service providers, ensure they include GDPR-compliant regulations for data processing and deletion.

•Zero Trust PrincipleXerox supports Zero Trust initiatives with a combination of hardware, software, and processes. This means that „no implicit trust“ is granted and every access, device, and user is continuously verified. This significantly strengthens your company's overall security posture.
