REV (10/2024)

SECURITY REQUIREMENTS - FACILITY SECURITY LEVEL III

THESE PARAGRAPHS CONTAIN ADDITIONAL SECURITY REQUIREMENTS THAT MAY BE

INSTALLED IN THE LEASED SPACE, AND UNLESS INDICATED OTHERWISE, ARE TO BE

PRICED AS PART OF THE BUILDING SPECIFIC AMORTIZED CAPITAL (BSAC). BECAUSE

EACH BUILDING IS UNIQUE, THE FINAL LIST OF SECURITY COUNTERMEASURES WILL BE

DETERMINED DURING THE DESIGN PHASE AND IDENTIFIED IN THE DESIGN INTENT

DRAWINGS AND CONSTRUCTION DOCUMENTS. AFTER COMPLETING THE

CONSTRUCTION DOCUMENTS, THE LESSOR SHALL SUBMIT A LIST OF THE ITEMIZED

COSTS. SUCH COSTS SHALL BE SUBJECT TO NEGOTIATION. MAINTENANCE COSTS ARE

TO BE INCLUDED IN THE OPERATING RENT.

NOTE THAT ITEMS IDENTIFIED AS “SHELL *” REPRESENT A LESSOR’S OBLIGATIONS OR

THE GOVERNMENT’S RIGHTS AND ARE NOT NECESSARILY ITEMS TO BE CONSTRUCTED.

DEFINITIONS: Definitions are the same as those used in the Lease unless re-defined in these Security Requirements.

CRITICAL AREAS AND SYSTEMS- The areas that house systems that if damaged and/or compromised could have significant adverse consequences for the facility, operation of the facility, or mission of the agency or its occupants and visitors. These areas may also be referred to as “limited access areas,” “restricted areas,” or “exclusionary zones.” Critical areas do not necessarily have to be within Government-controlled Space (e.g., generators, air handlers, electrical feeds, utilities, telecom closets or potable water supply that may be located outside Government-controlled Space).

DESIGN-BASIS THREAT – The Design-Basis Threat (DBT) is the profile and estimate of the threats to a Government facility across a range of specific undesirable events, and serves as the basis for determining appropriate security standards. The Lessor’s technical consultant(s) shall work in conjunction with the Government, including the Federal Protective Service (FPS), to apply the DBT to the post-award risk assessment. The risk assessment identifies recommended countermeasures and security design features that achieve the minimum baseline level of protection for a particular facility. The baseline level of protection may be further customized to address facility-specific conditions. The Lessor is responsible for providing countermeasure provisions outlined in this FSL document, as well as for additional items identified during the post-award risk assessment. Any additional countermeasures identified during this assessment shall be priced as BSAC.

Note: Where Government is less than 75% building occupancy, security guard patrol operations shall principally be conducted within, but not restricted to, Tenant space and for the sole benefit of the Government (bearing no responsibility for other Tenants, should there be any).

VII. CYBERSECURITY (SHELL *)

A. Lessors are prohibited from connecting any portion of their building and access control systems (BACS) to any federally-owned or operated IT network. BACS include systems providing fire and life safety control, physical access control, building power and energy control, electronic surveillance, and automated HVAC, elevator, or building monitoring and control services (including IP addressable devices, application servers, or network switches).

B. In the event of a cybersecurity incident related to BACS, the Lessor shall initially assess the cyber incident, identify the impacts and risks to the Building and its occupants, and follow their organization’s cyber and IT procedures and protocols related to containing and handling a cybersecurity incident. In addition, the Lessor shall immediately inform the Lease Contracting Officer’s (LCO’s) designated representative, i.e., the Lease Administration Manager (LAM), about cybersecurity incidents that impact a federal tenant’s safety, security, or proper functioning.

C. Lessors are encouraged to put into place the following cyber protection measures in order to safeguard facilities and occupants:

1. Engineer and install BACS to comply with the Department of Homeland Security Industrial Control Systems Computer Emergency Response Team (DHS ICS-CERT) cyber security guidance and recommendations (https://ics-cert.us-cert.gov/Recommended-Practices).

2. Refer to the National Institute of Standards and Technology Cyber Security Framework (NIST- CSF) (https://www.nist.gov/cyberframework) and cybersecurity guidance in the DHS Commercial Facilities Sector-Specific Plan (https://www.dhs.gov/publication/nipp-ssp-commercial-facilities-2015) for best practices to manage cyber risks.

https://ics-cert.us-cert.gov/Recommended-Practices https://www.nist.gov/cyberframework https://www.dhs.gov/publication/nipp-ssp-commercial-facilities-2015 https://www.dhs.gov/publication/nipp-ssp-commercial-facilities-2015

3. Encourage vendors of BACS to secure these devices and software through the following:

a. Develop and institute a proper Configuration Management Plan for the BACS devices and applications, so that the system can be supported.

b. Safeguard sensitive data and/or login credentials through the use of strong encryption on devices and applications. This means using NIST- approved encryption algorithms, secure protocols (i.e., Transport Layer Security (TLS) 1.1, TLS 1.2, TLS 1.3) and Federal Information Processing Standard (FIPS) 140-2 validated modules.

c. Disable unnecessary services in order to protect the system from unnecessary access and a potential exposure point by a malicious attacker. Examples include File Transfer Protocol- FTP (a protocol used for transferring files to a remote location) and Telnet (allowing a user to issue commands remotely). Additionally, use of protocols that transmit data in the clear (such as default ZigBee) should be avoided, in favor of protocols that are encrypted.

d. Close unnecessary open ports to secure against unprivileged access.

e. Monitor and free web applications and supporting servers of common vulnerabilities in web applications, such as those identified by the (Open Web Application Security Project (OWASP) Top 10 Project (https://www.owasp.org/index.php/Category:OWASP_Top_Ten_Project).

f. Enforce Least Privilege, where proper permissions are enforced on a device or application so that a malicious attacker cannot gain access to all data. Enforcing Least Privilege will only allow users to access data they are allowed to see. Additional information can be found at https://www.beyondtrust.com/blog/what-is-least-privilege/

g. Protect against Insufficient User Access Auditing, where device or application does not have a mechanism to log/track activity by user. Enforce changing of factory default Username and Password to prevent unauthorized entry into the BACS system.

h. Use updated antivirus software subscription at all times. Kaspersky-branded products or services, prohibited from use by the Federal Government, are not to be utilized.

i. Conduct antivirus and spyware scans on a regular basis. Patching for workstations and server Operating System (OS), as well as vulnerability patching should follow standard industry best practices for software development life cycle (SDLC).

j. Discontinue the use of end of life (EOL) systems and use only applications/systems that are supported by the manufacturer.

k. Operating Systems must be supported by the vendor for security updates (e.g., do not use Windows Server 2003).

l. Proposed standard installation, operation, maintenance, updates, and/or patching of software shall not alter the configuration settings from the approved United States Government Configuration Baseline (USGCB) or tenant agency guidance (if applicable).

m. Disallow the use of commercially-provided circuits to manage building systems and install building systems on a protected network, safeguarded by the enterprise firewalls in place.

https://www.owasp.org/index.php/Category:OWASP_Top_Ten_Project https://www.beyondtrust.com/blog/what-is-least-privilege/

Workstations or servers running building monitor and control systems are not connected and visible on the public internet.

n. Systems should have proper system configuration hardening and align with Center for Internet Security (CIS) benchmarks or other industry recognized benchmarks. Additional information can be found at https://www.cisecurity.org/cis-benchmarks/.
