Defense Information Systems Agency (DISA)
The Defense Information Systems Agency (DISA) established the Assured Compliance Assessment Solution (ACAS) as the enterprise-wide solution for vulnerability management and configuration for the U.S. Department of Defense (DoD). The entities ACAS supports are highly distributed, which required a security solution that was highly scalable, accurate, flexible and easy to deploy. After implementing and evaluating Tenable products over several months, DISA selected Tenable and partner DXC Technology (formerly HP Enterprise Services) for their ability to meet or or exceed DoD requirements. The selection of Tenable solutions as the foundation of ACAS helps confirm Tenable as the leader in vulnerability management for the U.S. federal government.
Key Business Needs
The Defense Information Systems Agency (DISA) is a U.S. Department of Defense (DoD) combat support agency. DISA recognized that the Secure Configuration Compliance Validation Initiative (SCCVI) software suite, previously acquired by the DoD, provided limited ability to quickly and accurately assess the security of enterprise networks. To address this, DISA established the Assured Compliance Assessment Solution (ACAS) as the DoD’s enterprise-wide solution for vulnerability management and configuration compliance. Because the entities that ACAS supports are highly distributed, DISA sought a flexible, accurate and scalable vulnerability management solution that was easy to deploy at all levels. It had to deliver real-time visibility and risk assessment across all DoD networks, enabling decisive, risk-based management decisions consistent with federal guidelines
Tenable Products Selected
After an extensive evaluation process, including a six-month, multi-site pilot implementation, DISA selected Tenable and partner DXC Technology (formerly HP Enterprise Services) for their unique ability to deliver a modern enterprise-class vulnerability management and configuration compliance solution meeting or exceeding DoD requirements. It included the SecurityCenter™ platform, integrated with Nessus® Network Monitor and Nessus®, the most widely-deployed vulnerability and compliance scanner in the world.
Tenable and DXC Technology provided DISA with a fast, accurate, cost-effective and highly scalable approach to real-time continuous monitoring that is cost-effective and easy to deploy across the DoD. Combining active and passive scanning technology and a flexible, fluid architecture, this proactive, automated solution provides DISA and its constituents with essential situational awareness and context, enabling true, risk-based management decisions that comply with both current and emerging federal guidelines. By choosing Tenable to support its ACAS solution, DISA helps reinforce the company as the federal government’s preferred vulnerability management provider.
With a vision to provide “information superiority in defense of our Nation,” the Defense Information Systems Agency (DISA), a U.S. Department of Defense (DoD) combat support agency, provides IT and communications support to national leaders, joint warfighters and other key mission and coalition partners who contribute to the defense of our country.
Recognizing its limited capability to quickly and accurately assess the security of enterprise networks, DISA established the Assured Compliance Assessment Solution (ACAS) to replace the Secure Configuration Compliance Validation Initiative (SCCVI) software suite previously acquired by DoD. ACAS fulfills a combination of operational and strategic objectives, including:
- Providing an innovative technical solution with a flexible cost structure
- Employing a commercial solution that can be easily ordered and quickly deployed across the DoD infrastructure
- Supporting enterprise-wide deployment, with the ability to tier system evaluation and management throughout the organization.
To support ACAS, DISA sought a comprehensive security solution that could quickly and accurately deliver a broad range of capabilities, including:
- Fast and accurate enterprise-wide network security assessment
- Increased accuracy of risk assessment and standards compliance verification
- High scalability and ease of deployment at all levels, from the Geographic Commandant Commander to the warfighter on the front lines
- Real-time risk assessment across DoD networks to provide essential situational awareness and enable true, risk-based management decisions consistent with existing and emerging federal guidelines
The Tenable Solution (Tenable – DXC Technology Partnership)
Tenable and DXC Technology (formerly HP Enterprise Systems), established an exclusive partnership to offer DISA an integrated software solution that is accurate, thorough, scalable, reliable, intuitive and easy to use. It can be easily deployed via download to all DoD components – without the need to procure and install appliance devices. No other tool can match the unique tiering ability Tenable offers, which allows DISA to aggregate security data in one central location to support its mission. This team united two key market leaders, which combined complementary skills and experience to offer a superior ACAS solution to DISA and the rest of DoD.
A Truly Distributed Enterprise
ACAS is the DoD’s enterprise-wide solution for vulnerability management and configuration compliance.The enterprise it spans includes:
- DoD Combatant Commands
- Four Military Services
- DoD Agencies and Field Activities
- Combat Support Agencies
- Defense Intelligence Agency
- National Geospatial-Intelligence Agency
- National Reconnaissance Office
- National Media Exploitation Center
- National Security Agency
- The U.S. Coast Guard, National Guard and Reserves
The distributed nature of such an extensive enterprise demands a solution that is extremely flexible and easy to use, but also highly scalable. Tenable SecurityCenter addresses these requirements by uniquely supporting multi-tier management, including both local and centralized control, analysis and reporting.
HPES (now DXC Technology) assessed several technical approaches and vulnerability tools in order to find the right solution/partner. This comprehensive assessment was driven by several key criteria, including knowledge and understanding of DoD enterprise networks, ability to meet Security Content Automation Protocol (SCAP) compliance and Common Criteria standards, implementation speed and flexibility, ability to meet ACAS requirements, operator ease of use and ability to meet long-term DoD enterprise needs.
Tenable chose HPES (now DXC Technology), because of its extensive DoD experience and the wide-ranging corporate reachback it provided as the industry’s largest technology company. HPES had one of the broadest portfolios of products, services, end-to-end solutions, and research and testing in the technology industry. It also had a long history in supporting Information Assurance (IA) / Computer Network Defense (CND) programs, and was able to draw upon the IA experience of nearly 2,000 certified professionals.
Unlike many security software solutions, Tenable built its licensing and deployment architecture with one goal in mind: to allow customers’ security monitoring strategies to be defined by their needs, not by license and cost restrictions. For DISA, that approach facilitates flexible scanner usage across the DoD infrastructure, enables an improved security posture, and enhances satisfaction of organizational requirements such as fault tolerance, the ability to target operational scanning windows and managerial reporting.
The Tenable Solution: Comprehensive, Enterprise-Class Vulnerability Management
DISA’s selection of Tenable followed an extensive evaluation process culminating with a six-month, multi-site pilot implementation. During this period, Tenable successfully demonstrated its ability to meet and exceed all DISA requirements for a modern, Enterprise-class vulnerability management and configuration compliance solution. Tenable provided an integrated approach to proactive network defense for the DoD, designed to scale easily while maintaining cost effectiveness. It leverages several Tenable components, including:
SecurityCenter provides continuous asset-based security and compliance monitoring, unifying the processes of asset discovery, vulnerability detection and configuration auditing. It delivers a central point for discovering assets, detecting vulnerabilities and data leaks, managing events and conducting configuration and compliance audits.
SecurityCenter is the first agent-less scanning solution to be certified by FDCC and SCAP.
The SecurityCenter console works with Nessus® scanners to look for policy changes every time a scan is requested. This provides the ability to assess an organization’s vulnerability and compliance posture, as well as delivering analysis and workflow tools that allow the user to easily perform reporting, auditing and remediation tasks.
SecurityCenter ties directly to DISA’s Information Assurance Vulnerability Management (IAVM) system. Upon receipt of a new or updated information Assurance Vulnerability Alert (IAVA), SecurityCenter immediately deploys a new policy to Nessus scanners. That capability eliminates often time-consuming waits for new policies to be manually written, improving security. SecurityCenter also has a built-in reporting engine which already produces the common reports DISA needs – without advanced scripting. ACAS users quickly gain access to relevant data to efficiently create meaningful reports.
Nessus® Vulnerability Scanner
A high-quality, full-function scanner covers a breadth of vulnerability and configuration checks across a broad range of different workstation, server and network devices. The Tenable Nessus scanner supports more than 87,428 plug-ins and covers more than 38,439 unique Common Vulnerabilities and Exposures (CVEs). The scanner is fast and accurate, giving clients the greatest possible visibility into the status of connected devices and systems. The popular Nessus scanner has been downloaded more than ten million times.
Nessus® Network Monitor
Traditional active scanning systems miss transient devices – like smartphones – as well as many cloud-based services, resulting in dangerous gaps in coverage and visibility. So sophisticated security professionals complement active scanning with passive scanning. Nessus Network Monitor (formerly Passive Vulnerability Scanner or PVS) uniquely overcomes these limitations, effectively extending scanning visibility to resources that would otherwise be missed in assessments. It introduces real-time monitoring, identifying devices and systems, applications and services, and network connections, as well as eliminating the restrictions and limitations of traditional, schedule-based scanning. The inclusion of passive vulnerability scanning provides a comprehensive solution for DISA.
The Tenable Advantage:
- Flexibility – the option to deploy unlimited consoles and scanners enables DISA to build the optimal scanning strategy, reflecting environmental, architectural and organization requirements.
- Scalability – with the ability of individual SecurityCenter consoles to scan hundreds of thousands of IPs, scanning architectures are based on mission requirements, not technology constraints.
- Accuracy – the comprehensive Nessus library of more than 87,428 individual plug-ins helps eliminate missed events (i.e., false negatives), while the popularity of Nessus provides an immediate feedback loop and extra layer of quality assurance.
- Easy to deploy, use and maintain – the broad platform support Tenable provides for scanners has no relational database to maintain and no agents to manage.
- Continuous monitoring – passive scanning capabilities, unique to Tenable, help DISA move beyond static, point in time assessments.
- Experience – the combination of one of the world’s largest technology companies with one of the most widely-used vulnerability scanners gives DISA a partner it can trust.
The Tenable software-only approach means components are easily procured and deployed on industry-standard architecture hardware, not proprietary appliances. This means DoD can expand and adapt its scanning architecture as required by operational demands, without the delays and costs associated with buying, shipping and maintaining appliance inventory. Additionally, our solution can run on the government’s existing platform, minimizing disruptions during transition.
For DISA and its constituents, ACAS provides the evolution necessary to properly support today’s cyber warfighter. The Tenable solution delivers a holistic, highly automated and accurate approach to real-time continuous monitoring. Combining active and passive scanning technologies within a fluid, flexible architecture, the Tenable solution provides the sophistication and flexibility needed to satisfy the wide variety of security needs the Department of Defense must support.
By meeting and exceeding the vulnerability, configuration and real-time risk management needs of one of the largest and most demanding government organizations in the world. The selection of Tenable as the foundation of the Assured Compliance Assessment Solution (ACAS) helps cement Tenable as the undisputed leader in vulnerability management in the U.S. federal government.
