1 Executive Summary
This report is intended to assist the end-user of this product and any security certification agent for that end-
user in determining the suitability of this Information Technology (IT) product for their environment. End-
users should review the Security Target (ST), which is where specific security claims are made, in
conjunction with this Validation Report (VR), which describes how those security claims were evaluated
and tested and any restrictions on the evaluated configuration. Prospective users should read carefully the
Assumptions and Clarification of Scope in Section 4 and the Validator Comments in Section 10, where any
restrictions on the evaluated configuration are highlighted.
This report documents the National Information Assurance Partnership (NIAP) assessment of the
evaluation of the PrinterLogic Web Stack Server 18.3. It presents the evaluation results, their justifications,
and the conformance results. This VR is not an endorsement of the Target of Evaluation (TOE) by any
agency of the U.S. Government and no warranty of the TOE is either expressed or implied. This VR applies
only to the specific version and configuration of the product as evaluated and as documented in the ST.
The evaluation of PrinterLogic Web Stack Server was performed by Leidos Common Criteria Testing
Laboratory (CCTL) in Columbia, Maryland, in the United States and was completed in November 2019.
The evaluation was conducted in accordance with the requirements of the Common Criteria and Common
Methodology for IT Security Evaluation (CEM), version 3.1, revision 5 and assurance activities specified
in Protection Profile for Application Software, Version 1.3, 1 March 2019.
The evaluation was consistent with NIAP Common Criteria Evaluation and Validation Scheme (CCEVS)
policies and practices as described on their web site (www.niap-ccevs.org).
The Leidos evaluation team determined that PrinterLogic Web Stack Server is conformant to the claimed
Protection Profile (PP) and, when installed, configured and operated as specified in the evaluated guidance
documentation, satisfies all of the security functional requirements stated in the ST. The information in this
VR is largely derived from the Assurance Activities Report (AAR) and associated test report produced by
the Leidos evaluation team.
PrinterLogic Web Stack Server is a product that provides centralized services for user installation of print
drivers as well as pull printing and cloud printing functionality.
PrinterLogic Web Stack Server can be used to centrally manage direct IP printing. Printers can be added,
modified (e.g. driver, port, name, duplex option), and removed from a centralized Admin Console. These
changes are then provisioned to individual PrinterLogic Web Stack Client (PL Client) applications installed
on user workstations in the operational environment. End users are provided a Self-Service Portal where
they can install additional print drivers above and beyond those provisioned for them. They are also
provided a Release Portal where held pull print jobs can be released to a selected printer. Authorizations
are based on Active Directory attributes, so users may be given access (or the ability to gain access) to
different printers based on role, geographic location, or other attributes.
PrinterLogic Web Stack Server is evaluated as a software application only. PrinterLogic Web Stack Server
contains functionality that is not covered by Protection Profile for Application Software. As with all
evaluations claiming conformance to a NIAP-approved protection profile, only the functionality specified
in the ST is evaluated.
The validation team monitored the activities of the evaluation team, examined evaluation evidence,
provided guidance on technical issues and evaluation processes, and reviewed the evaluation results
produced by the evaluation team. The validation team found that the evaluation results showed that all
assurance activities specified in the claimed PPs had been completed successfully and that the product
satisfies all of the security functional and assurance requirements stated in the ST. Therefore the validation
team concludes that the testing laboratory’s findings are accurate, the conclusions justified, and the

conformance results are correct. The conclusions of the testing laboratory in the evaluation technical report
are consistent with the evidence produced.

2 Identification
The CCEVS is a joint National Security Agency (NSA) and National Institute of Standards and Technology
(NIST) effort to establish commercial facilities to perform trusted product evaluations. Under this program,
security evaluations are conducted by commercial testing laboratories called Common Criteria Testing
Laboratories (CCTLs) in accordance with National Voluntary Laboratory Assessment Program (NVLAP)
accreditation.
The NIAP Validation Body assigns Validators to monitor the CCTLs to ensure quality and consistency
across evaluations. Developers of information technology products desiring a security evaluation contract
with a CCTL and pay a fee for their product’s evaluation. Upon successful completion of the evaluation,
the product is added to NIAP’s Product Compliant List (PCL).
The following table identifies the evaluated Security Target and TOE.

2.1 Threats
The ST references the Protection Profile for Application Software, Version 1.3, 1 March 2019. The
protection profile identifies the following threats, which the TOE and its operational environment are
intended to counter:
 An attacker is positioned on a communications channel or elsewhere on the network infrastructure.
Attackers may engage in communications with the application software or alter communications
between the application software and other endpoints in order to compromise it.
 An attacker is positioned on a communications channel or elsewhere on the network infrastructure.
Attackers may monitor and gain access to data exchanged between the application and other
endpoints.
 An attacker can act through unprivileged software on the same computing platform on which the
application executes. Attackers may provide maliciously formatted input to the application in the
form of files or other local communications.
 An attacker may try to access sensitive data at rest.
2.2 Assumptions
 The TOE relies upon a trustworthy computing platform for its execution. This includes the
underlying platform and whatever runtime environment it provides to the TOE.
VALIDATION REPORT

 The user of the application software is not willfully negligent or hostile, and uses the software in
compliance with the applied enterprise security policy.
 The administrator of the application software is not careless, willfully negligent or hostile, and
administers the software within compliance of the applied enterprise security policy.
2.3 Organizational Security Policies
There are no Organizational Security Policies defined for the application in the PP.

4 Clarification of Scope
All evaluations (and all products) have limitations, as well as potential misconceptions that need clarifying.
This text covers some of the more important limitations and clarifications of this evaluation. Note that:
1. As with any evaluation, this evaluation only shows that the evaluated configuration meets the
security claims made, with a certain level of assurance (the assurance activities specified in the
claimed PPs and performed by the evaluation team).
2. This evaluation covers only the specific software version identified in this document, and not any
earlier or later versions released or in process.
3. The evaluation of security functionality of the product was limited to the functionality specified in
the claimed PPs and scoped to those Security Functional Requirements (SFRs) declared in the ST.
Any additional security related functional capabilities of the product were not covered by this
evaluation.
4. This evaluation did not specifically search for, nor attempt to exploit, vulnerabilities that were not
“obvious” or vulnerabilities to objectives not claimed in the ST. The CEM defines an “obvious”
vulnerability as one that is easily exploited with a minimum of understanding of the TOE, technical
sophistication and resources.
5. The following TOE functionality is specifically excluded in the ST and therefore outside the scope
of this evaluation:
 Installation of print drivers on client PCs.
 Transmission of print job data from host platforms to target printers or other parts of the
TOE operational environment.
 Configuration of network settings and email servers that allow print data to be received by
the TOE.
VALIDATION REPORT

5 Security Policy
The TOE enforces the following security policies as described in the ST.
5.1 Cryptographic Support
The TOE uses NIST-validated cryptographic algorithms to secure data in transit. The TOE relies on the
FIPS-validated cryptographic library cng.sys provided by Windows to perform cryptographic
functionality. The TSF encrypts credential data stored by the TOE in the environmental SQL database.
The TOE relies on its underlying OS platform to implement TLS/HTTPS server functionality. The TOE
also relies on its underlying OS platform to provide entropy used for key generation.
5.2 User Data Protection
The TSF leverages functionality provided by their underlying OS platform to secure sensitive data at rest.
The TOE uses network resources provided by the underlying platform. All platform services are invoked
with user awareness and authorization.
The TOE uses network connectivity to handle interactive user and administrator sessions and to
communicate with environmental PL Clients for the purpose of applying configuration changes and
updating the status of held print jobs.
5.3 Security Management
The Web Server provides an Admin Console GUI for configuration of environmental PL Client activity.
Specifically, an administrator can designate a PL Client as a Service Host and configure it to work with
email printing and mobile printing, thus defining the trusted channels used by a PL Client.
The Web Server also provides Self-Service Portal and Release Portal GUIs that allow users to control
printing activity. The Release Portal is used to release print jobs, which prompts secure communications
back to environmental PL Clients (Service Hosts) to initiate the print operation.
Authentication to the Web Server is performed using locally-defined credentials. On initial installation, the
administrator is prompted to specify credentials to be used for the Admin Console.
TOE configuration data is stored locally in the Windows Registry.
5.4 Privacy
The TOE does not handle personally identifiable information (PII).
5.5 Protection of the TSF
The TOE includes measures to integrate securely with its underlying OS platform. The TOE does not
perform explicit memory mapping and it does not allocate any memory region with both write and execute
permissions. Similarly, the TSF does not write user-modifiable data to directories that contain executable
files. The TOE is compatible with its host OS platform when that platform is configured in a secure manner.
The TOE is not written in a language that is susceptible to stack-based buffer overflow attacks.
The TOE uses a well-defined set of platform APIs and third party libraries.
The TOE provides the ability for a user/administrator to check its version and to apply updates. Updates
are delivered in formats appropriate for the platform on which the TOE is installed. Application of an update
VALIDATION REPORT
PrinterLogic Web Stack Server
9
removes all executable code associated with the application; there is no way for the application to modify
its own code. Updates the TOE are digitally signed, and the signature is validated prior to installation.
5.6 Trusted Path/Channels
TOE components use trusted paths and channels to secure data in transit. The following interfaces are
provided by each TOE component:
 Web Server:
o TLS/HTTPS server for remote user/administrator access
o TLS/HTTPS server for changes to PL Client configuration data and pull printing status

7 Independent Testing
This section describes the testing efforts of the evaluation team. It is derived from information contained in
the following:
 PrinterLogic Web Stack Server Common Criteria Assurance Activities Report, Version 1.0, 27
November 2019
The purpose of this activity was to confirm the TOE behaves in accordance with the TOE security functional
requirements as specified in the ST for a product claiming conformance to the Protection Profile for
Application Software, Version 1.3, 1 March 2019.
To this end, the evaluation team devised a Test Plan based on the Testing Assurance Activities specified in
the above-referenced Protection Profile.
The Test Plan described how each test activity was to be instantiated within the TOE test environment. The
evaluation team executed the tests specified in the Test Plan and documented the results in the team test
report listed above.
Testing of the TOE was performed in the summer of 2019 at Leidos’s Accredited Test & Evaluation lab.
The evaluators received the TOE in the form that normal customers would receive it, installed and
configured the TOE in accordance with the provided guidance, and exercised the Team Test Plan on
equipment configured in the testing laboratory. For the purposes of testing, the configuration depicted in
Figure 2 was used for testing the TOE.
Note that the TOE was tested in conjunction with VID11057. These two products are designed to function
together in a production environment, although the TOE was demonstrated to meet all mandatory PP
requirements as a standalone product.

o OpenLDAP 2.4.46
o Wireshark 2.4.4
 Active Directory Server running Windows Server 2012 R2
Given the complete set of test results from the test procedures exercised by the evaluators, the testing
requirements for the Protection Profile for Application Software, Version 1.3, 1 March 2019 are fulfilled.
7.1 Penetration Testing
The evaluation team conducted an open-source search for vulnerabilities in the product. The evaluator
searched the internet for potential vulnerabilities in the TOE using the following sources of the publicly
available information:
 http://nvd.nist.gov
 http://www.us-cert.gov
 http://securityfocus.com
The search was conducted using the following terms:
 PrinterLogic
 Printer Installer
 TLS 1.2
 OpenSSL 1.0.2h
Note: In October 2019 PrinterLogic began the process of rebranding their product as PrinterLogic Web
Stack which was a change from their old Printer Installer name. A vulnerability search was still conducted
on Printer Installer because any vulnerabilities found prior to the fall of 2019 would have been listed under
that name. Additionally, a search for PrinterLogic should cover any vulnerabilities listed under PrinterLogic
Web Stack.
The search was performed on September 6, 2019 and updated to check for new vulnerabilities on October
22, 2019. The open-source search did not identify any vulnerability applicable to the TOE in its evaluated
configuration. No additional testing was required to verify the vulnerabilities were mitigated.
