Overview
All CIS Benchmarks™ (Benchmarks) focus on technical configuration settings used to
maintain and/or increase the security of the addressed technology, and they should be
used in conjunction with other essential cyber hygiene tasks like:
• Monitoring the base operating system and applications for vulnerabilities and
quickly updating with the latest security patches.
• End-point protection (Antivirus software, Endpoint Detection and Response
(EDR), etc.).
• Logging and monitoring user and system activity.
In the end, the Benchmarks are designed to be a key component of a comprehensive
cybersecurity program.
Important Usage Information
All Benchmarks are available free for non-commercial use from the CIS Website. They
can be used to manually assess and remediate systems and applications. In lieu of
manual assessment and remediation, there are several tools available to assist with
assessment:
• CIS Configuration Assessment Tool (CIS-CAT® Pro Assessor)
• CIS Benchmarks™ Certified 3rd Party Tooling
These tools make the hardening process much more scalable for large numbers of
systems and applications.
NOTE: Some tooling focuses only on the Benchmark Recommendations that can
be fully automated (skipping ones marked Manual). It is important that ALL
Recommendations (Automated and Manual) be addressed since all are
important for properly securing systems and are typically in scope for
audits.
Key Stakeholders
Cybersecurity is a collaborative effort, and cross functional cooperation is imperative
within an organization to discuss, test, and deploy Benchmarks in an effective and
efficient way. The Benchmarks are developed to be best practice configuration
guidelines applicable to a wide range of use cases. In some organizations, exceptions
to specific Recommendations will be needed, and this team should work to prioritize the
problematic Recommendations based on several factors like risk, time, cost, and labor.
These exceptions should be properly categorized and documented for auditing
purposes.
Page 4
Apply the Correct Version of a Benchmark
Benchmarks are developed and tested for a specific set of products and versions and
applying an incorrect Benchmark to a system can cause the resulting pass/fail score to
be incorrect. This is due to the assessment of settings that do not apply to the target
systems. To assure the correct Benchmark is being assessed:
• Deploy the Benchmark applicable to the way settings are managed in the
environment: An example of this is the Microsoft Windows family of
Benchmarks, which have separate Benchmarks for Group Policy, Intune, and
Stand-alone systems based upon how system management is deployed.
Applying the wrong Benchmark in this case will give invalid results.
• Use the most recent version of a Benchmark: This is true for all Benchmarks,
but especially true for cloud technologies. Cloud technologies change frequently
and using an older version of a Benchmark may have invalid methods for
auditing and remediation.
Exceptions
The guidance items in the Benchmarks are called recommendations and not
requirements, and exceptions to some of them are expected and acceptable. The
Benchmarks strive to be a secure baseline, or starting point, for a specific technology,
with known issues identified during Benchmark development are documented in the
Impact section of each Recommendation. In addition, organizational, system specific
requirements, or local site policy may require changes as well, or an exception to a
Recommendation or group of Recommendations (e.g. A Benchmark could Recommend
that a Web server not be installed on the system, but if a system's primary purpose is to
function as a Webserver, there should be a documented exception to this
Recommendation for that specific server).
In the end, exceptions to some Benchmark Recommendations are common and
acceptable, and should be handled as follows:
• The reasons for the exception should be reviewed cross-functionally and be well
documented for audit purposes.
• A plan should be developed for mitigating, or eliminating, the exception in the
future, if applicable.
• If the organization decides to accept the risk of this exception (not work toward
mitigation or elimination), this should be documented for audit purposes.
It is the responsibility of the organization to determine their overall security policy, and
which settings are applicable to their unique needs based on the overall risk profile for
the organization.

Remediation
CIS has developed Build Kits for many technologies to assist in the automation of
hardening systems. Build Kits are designed to correspond to Benchmark's
“Remediation” section, which provides the manual remediation steps necessary to make
that Recommendation compliant to the Benchmark.
When remediating systems (changing configuration settings on
deployed systems as per the Benchmark's Recommendations),
please approach this with caution and test thoroughly.
The following is a reasonable remediation approach to follow:
• CIS Build Kits, or internally developed remediation methods should never be
applied to production systems without proper testing.
• Proper testing consists of the following:
o Understand the configuration (including installed applications) of the targeted
systems. Various parts of the organization may need different configurations
(e.g., software developers vs standard office workers).
o Read the Impact section of the given Recommendation to help determine if
there might be an issue with the targeted systems.
o Test the configuration changes with representative lab system(s). If issues
arise during testing, they can be resolved prior to deploying to any production
systems.
o When testing is complete, initially deploy to a small sub-set of production
systems and monitor closely for issues. If there are issues, they can be
resolved prior to deploying more broadly.
o When the initial deployment above is completes successfully, iteratively
deploy to additional systems and monitor closely for issues. Repeat this
process until the full deployment is complete.
Summary
Using the Benchmarks Certified tools, working as a team with key stakeholders, being
selective with exceptions, and being careful with remediation deployment, it is possible
to harden large numbers of deployed systems in a cost effective, efficient, and safe
manner.
NOTE: As previously stated, the PDF versions of the CIS Benchmarks™ are
available for free, non-commercial use on the CIS Website. All other formats
of the CIS Benchmarks™ (MS Word, Excel, and Build Kits) are available for
CIS SecureSuite® members.
CIS-CAT® Pro is also available to CIS SecureSuite® members.

Target Technology Details
This document provides prescriptive guidance for establishing a secure configuration
posture for Visual Studio Code. This guide was tested against VS Code version 1.104
on a Windows Server 2025 operating system. To obtain the latest version of this guide,
please visit http://benchmarks.cisecurity.org. If you have questions, comments, or have
identified ways to improve this guide, please write us at [email protected].
Intended Audience
This benchmark is intended for system and application administrators, security
specialists, auditors, help desk, and platform deployment personnel who plan to
develop, deploy, assess, or secure solutions that incorporate Visual Studio Code via
Group Policy Objects (GPOs).
Page 7
Consensus Guidance
This CIS Benchmark™ was created using a consensus review process comprised of a
global community of subject matter experts. The process combines real world
experience with data-based information to create technology specific guidance to assist
users to secure their environments. Consensus participants provide perspective from a
diverse set of backgrounds including consulting, software development, audit and
compliance, security research, operations, government, and legal.
Each CIS Benchmark undergoes two phases of consensus review. The first phase
occurs during initial Benchmark development. During this phase, subject matter experts
convene to discuss, create, and test working drafts of the Benchmark. This discussion
occurs until consensus has been reached on Benchmark recommendations. The
second phase begins after the Benchmark has been published. During this phase, all
feedback provided by the Internet community is reviewed by the consensus team for
incorporation in the Benchmark. If you are interested in participating in the consensus
process, please visit https://workbench.cisecurity.org/.

Recommendation Definitions
The following defines the various components included in a CIS recommendation as
applicable. If any of the components are not applicable it will be noted, or the
component will not be included in the recommendation.
Title
Concise description for the recommendation's intended configuration.
Assessment Status
An assessment status is included for every recommendation. The assessment status
indicates whether the given recommendation can be automated or requires manual
steps to implement. Both statuses are equally important and are determined and
supported as defined below:
Automated
Represents recommendations for which assessment of a technical control can be fully
automated and validated to a pass/fail state. Recommendations will include the
necessary information to implement automation.
Manual
Represents recommendations for which assessment of a technical control cannot be
fully automated and requires all or some manual steps to validate that the configured
state is set as expected. The expected state can vary depending on the environment.
Profile
A collection of recommendations for securing a technology or a supporting platform.
Most benchmarks include at least a Level 1 and Level 2 Profile. Level 2 extends Level 1
recommendations and is not a standalone profile. The Profile Definitions section in the
benchmark provides the definitions as they pertain to the recommendations included for
the technology.
Description
Detailed information pertaining to the setting with which the recommendation is
concerned. In some cases, the description will include the recommended value.
Rationale Statement
Detailed reasoning for the recommendation to provide the user a clear and concise
understanding on the importance of the recommendation.
Page 10
Impact Statement
Any security, functionality, or operational consequences that can result from following
the recommendation.
Audit Procedure
Systematic instructions for determining if the target system complies with the
recommendation.
Remediation Procedure
Systematic instructions for applying recommendations to the target system to bring it
into compliance according to the recommendation.
Default Value
Default value for the given setting in this recommendation, if known. If not known, either
not configured or not defined will be applied.
References
Additional documentation relative to the recommendation.
CIS Critical Security Controls® (CIS Controls®)
The mapping between a recommendation and the CIS Controls is organized by CIS
Controls version, Safeguard, and Implementation Group (IG). The Benchmark in its
entirety addresses the CIS Controls safeguards of (v7) “5.1 - Establish Secure
Configurations” and (v8) '4.1 - Establish and Maintain a Secure Configuration Process”
so individual recommendations will not be mapped to these safeguards.
Additional Information
Supplementary information that does not correspond to any other field but may be
useful to the user.
Page 11
Profile Definitions
The following configuration profiles are defined by this Benchmark:
• Level 1
Items in this profile intend to:
o be the starting baseline for most organizations;
o be practical and prudent;
o provide a clear security benefit; and
o not inhibit the utility of the technology beyond acceptable means.
• Level 2
This profile extends the "Level 1" profile. Items in this profile exhibit one or more
of the following characteristics:
o are intended for environments or use cases where security is more critical
than manageability and usability;
o may negatively inhibit the utility or performance of the technology; and
o limit the ability of remote management/access.
