Simplify NIST Compliance
Government business is now increasingly digitized and subcontracted. This has led to an explosion of government data held in the information systems of subcontractors, including sensitive or confidential data related to agriculture, finance, military, and other areas regulated by federal government agencies.
To keep this information secure, Executive Order 13556 established the Controlled Unclassified Information (CUI) program to standardize the way federal contractors handle unclassified information that requires protection, such as personally identifiable information or sensitive government assets.
The program issued final guidelines for protecting this data in "Protecting Controlled Unclassified Information in Nonfederal Information Systems and Organizations," known as the NIST 800-171 standard. The US Department of Defense announced that its contractors must meet this standard or risk losing their contracts.
Arctic Wolf® enables defense contractors and other government contractors to meet many of the NIST 800-171 compliance requirements using the industry-leading Arctic Wolf® Managed Detection and Response, and Arctic Wolf® Managed Risk offerings. Arctic Wolf simplifies compliance and compliance reporting with the help of a dedicated Concierge Security® Team of engineers assigned to your account.
Simplify NIST Compliance Requirements
Controlled Unclassified Information (CUI) can be stored in a variety of repositories, such as file servers, databases, access logs, and other types of unstructured and structured data repositories. Safeguarding access to CUI and defending it from outside attack requires diligent administration and close cooperation between IT teams and the many business units that need to access the data. Finding the right balance between the tasks supported by your IT organization and the checks automated through Arctic Wolf enables you to streamline NIST 800-171 compliance and reduce costs. Arctic Wolf validates several primary requirements of NIST 800-171, including basic and derived security requirements in the following areas:
|Sec. 3.1||Access Control|
|Sec. 3.3||Audit and Accountability|
|Sec. 3.4||Configuration Management|
|Sec. 3.5||Identification and Authentication|
|Sec. 3.6||Incident Response|
|Sec. 3.8||Media Protection|
|Sec. 3.11||Risk Assessment|
|Sec. 3.12||Security Assessment|
|Sec. 3.13||System and Communication Protection|
|Sec. 3.14||System and Information Integrity|
A full list of NIST 800-171 requirements is available from the National Institute of Standards website.
"Arctic Wolf security operations include everything Sparks needs for a comprehensive security operations function. We looked at alternatives from some of the largest IT security vendors and went with Arctic Wolf because it was easy to purchase and deploy, and was priced in a predictable way. To build the equivalent of the service internally would cost at least 10 times more."
— Steve Davidek, IT Manager, City of Sparks, Nevada
Arctic Wolf Compliance Solution for NIST 800-171
Arctic Wolf Managed Detection and Response (MDR) monitors activity in on- premises IT infrastructure and in cloud applications using Arctic Wolf sensors. Arctic Wolf MDR continuously monitors network flows and ingests log records from an unlimited number of log sources, and uses human-assisted machine learning to accurately detect and respond to advanced attacks. Arctic Wolf monitors on-premises environments as well as cloud environments, including infrastructure-as-a-service (AWS, Azure) and software-as-a-service (Office 365, G Suite, Box, Salesforce, etc.).
The Arctic Wolf Managed Risk solution is a vulnerability assessment service managed by security experts. The solution enables you to continuously scan your networks and endpoints, as well as quantify risk-based vulnerabilities.
The Arctic Wolf Concierge Security Team (CST) extends your IT staff with security expertise, hunts down advanced zero-day attacks, and provides customized compliance reports to meet your NIST requirements. The table below shows how Arctic Wolf enables you to address and provide evidence for several key areas of NIST requirements.
