USA Cybersecurity is a veteran owned small business located in Washington, D.C. certified to deliver cybersecurity and digital forensic services to government agencies, government contractors and commercial businesses.
Supervisory Control and Data Acquisition (SCADA) is a centralized control system network architecture containing computers and applications that perform key functions in providing essential services and commodities such as electricity, natural gas, water, waste treatment, and transportation throughout the United States. USA Cybersecurity is a veteran owned small business located in Washington, DC. certified to deliver cybersecurity and digital forensic services to government agencies, government contractors and commercial businesses. By allowing the collection and analysis of data and the control of equipment, such as pumps and valves, from remote locations, SCADA networks provide great efficiency and are widely used. They are also a security risk. SCADA is an integral part of the Nation’s critical infrastructure and requires protection from a variety of threats that exist in today’s cyber space.
Our managed services and regulatory compliance offerings include using the brightest security-cleared minds and the most sophisticated equipment available. Our primary focus is to secure the infrastructure of the Continental United States (CONUS). Our secondary focus is to secure the infrastructure of our allies and friends Outside Continental United States (OCONUS). All services are provided remotely or in-person.
SCADA networks were initially designed to maximize functionality, with little attention paid to security. As a result, performance, reliability, flexibility and safety of distributed control/SCADA systems are robust, while the security of these systems themselves is often lacking. This resulting lack of security makes some SCADA networks potentially vulnerable to the disruption of services, process redirection, or manipulation of operational data resulting in public safety concerns and/or serious disruptions to the Nation’s critical infrastructure. Action is required by all organizations, Government and commercial, to secure SCADA networks as part of the effort to adequately protect the Nation’s critical infrastructure.
The President’s Critical Infrastructure Protection Board, along with the Department of Energy, has developed the steps outlined below to assist the organizations improve the security of their SCADA networks . These steps are not meant to be prescriptive or all-inclusive; however, they do address the essential actions that need to be taken to improve the protection of SCADA networks. The steps are divided into two categories: specific actions to improve implementation, and, actions to establish essential underlying management processes and policies.
OT and IoT
Cyber Security Platform For Critical Infrastructure & Enterprises
The Internet of Things (IoT) has changed the landscape of the energy industry. IP-enabled networks connect the operational technology (OT) side at the utility and the information technology (IT) side. This means a convergence between SCADA, AMI, DA and consumer engagement systems. USA Cybersecurity SCADA protection secures industrial networks as they increase automation, digitization and connectivity.

Step by step guide for best practices of OT security and what actions should be taken to achieve them.
Incident Response and Forensics
Incident response in OT or an ICS environment is substantially different from that of IT. There are different considerations and priorities in an OT environment and so, while many organizations try to leverage their existing IT incident response capabilities in an OT environment, this may lead to additional damage or an ineffective response. Our response teams have the right mixture of OT experience and security understanding. This makes them ideal in times of crisis. Our teams are distributed globally and ready to support you at any given moment, 24/7.
IT SecOPs practices are in most cases more mature than at their OT counterparts and the characteristics of the two environments are worlds apart. For example, while isolation of a specific endpoint in IT would be deemed as common practice in an event of a breach, isolating an asset in OT disrupts critical production and may cause substantial damage. To help align the worlds of IT and OT, we offer the following services:
Reviewing the current process and frameworks of both the IT and OT security practices to eliminate any gaps in the response capabilities of your security operations, suggesting best practice for complex OT infrastructure.

The Heart of our Technology
USA Cybersecurity offers a wide range of cutting-edge capabilities built from the ground up to monitor large-scale complex OT networks
Comprehensive Cybersecurity for Discrete & Process Manufacturing Technologies
USA Cybersecurity helps manufacturers gain full visibility and risk management over their OT networks while adopting Industrial IoT technologies.
Manufacturing Industry Security Challenges
The Industrial IoT digital transformation is revolutionizing manufacturing networks, but the adoption of the advanced technologies is creating new challenges for IT/OT security teams:
Manufacturing industries are increasingly migrating to smart manufacturing technologies as part of the ongoing fourth industrial revolution. With increased connectivity and advanced automation systems such as manufacturing execution systems (MES) that integrate plant floor production (ICS/SCADA networks) and enterprise resource planning (ERP) systems, manufacturing objectives revolve around maximizing productivity, but at the same time, they create new vulnerabilities and risks such as production manipulation, operational downtime, and sensitive data-theft threats.
In the last 5 years, manufacturing industries have been the victims of an increased number of cyberattacks, such as the Havex/Dragonfly campaign that targeted industrial control systems across the USA and Europe or the most well-known WannaCry and NotPetya that caused havoc in the automotive, food, pharmaceutical, and other manufacturing plants. Events like these result in significant revenue loss valued in the hundreds of millions of dollars, reputation damage, loss of competitive edge, and sometimes public and employee safety issues.
Critical Infrastructure Protection
USA Cybersecurity enables critical infrastructure providers to stay secure against growing modern cyber threats by providing a critical infrastructure cybersecurity platform.
Critical Infrastructure Cybersecurity Challenges
Critical infrastructure and utilities are heavily depended on their critical assets in operational environments to run reliably. Thus the cyber security infrastructure needs to be at the highest level.
Critical infrastructure foundation is built on industrial control systems such as SCADA systems and other OT systems. Modern operational networks are constantly evolving due to developments, such as; Industrial Internet of Things (IIoT), Industry 4.0, smart grid and others. With the increase in complexity, comes increased risk. Cyber-attacks against OT networks in critical infrastructure can lead to devastating outcomes, with critical operational downtime being the prime target. New cyber-threats against operational networks in critical infrastructure are forcing operators to change their approach and strategy regarding OT security. Since connectivity and adoption of IIoT devices is inevitable due to business requirements, operators must start planning how they can remain secure while increasing connectivity instead of depending on outdated approaches such as air-gapping between IT and OT. This will allow them to protect themselves from attacks trying to disrupt their operations.
Securing Building Management Systems (BMS)
USA Cybersecurity provides building operators the peace of mind to optimize their BMS systems while keeping them safe and secure
Smart Buildings Cybersecurity Challenges
Smart buildings are adopting a wide range of IoT technologies to optimize critical systems such as physical security, energy management, and HVAC, and are therefore more exposed to risks:
As the trend toward smart buildings accelerates, the sophistication of these buildings is on the rise. More and more aspects of building management are being digitized and centrally managed. The benefits of making buildings smarter include: optimized energy consumption, reduced operational costs, and improved personal safety and security. In order to achieve these benefits, Building Management Systems (BMS) require increased connectivity: within each BMS, among separate buildings or even within entire smart city systems and the internet more widely. All these advancements in connectivity incur security risks. The devices that control physical environments, are now much more susceptible to malicious attacks. The criticality of these systems makes them an inviting target for deliberate attacks. Coordinated attacks or failures in tandem with other emergency events can further increase the potential for significant damage. For example, simultaneous failures in fire safety systems, door controls, HVACs and other systems, at the time of a fire, can cause disastrous results.
USA Cybersecurity Secures Building Management Systems
USA Cybersecurity provides building operators with the required tools to gain visibility within their building management systems (BMS) and to continuously ensure that risks and threats are contained:
Our platform keeps Building Management Systems (BMS) running securely with full network assets detection and mapping, continuous network traffic monitoring, and identification of anomalies and unauthorized actions. It helps map the smart building network, secure it, and improve its operational availability.

The lab runs equipment that includes many types of PLC's, HMI's, vendor-specific engineering software, protocol converters and I/O modules.
Designed to Scale
Our platform is the only solution purposely built to support the size and diversity in large-scale, complex industrial networks.
USA Cybersecurity platform was designed with the unique capability of real time, wire-speed deep packet inspection, allowing it to analyze 100% of network traffic and provide protection in any architecture – including large-scale industrial networks. Traditional OT networks were typically characterized with small networks and deterministic communication patterns. In contrast, modern large-scale OT networks include thousands of assets with a high traffic rate, “noisy” activities, and diverse and complex communication patterns. In some cases, the same production line is used to produce several different products in a short period of time. This requires frequent changes to the production process logic and creates a dynamic OT environment.
Securing Complex OT Networks
Full Coverage and Protection for best-in-class packet processing performance, we can support 10Ks of assets with high bandwidth communications without applying traffic filtering or sampling, and so without a negative effect on operations. Large Scale Security and Usability with algorithms that leverage advanced machine learning capabilities, our platform is able to learn network groups and reduce false positives, while providing a simple, friendly user interface. Cost Effective integration platform require fewer integration points, decreasing the number of sensors required and significantly reducing hardware requirements and maintenance costs.
The following steps focus on specific actions to be taken to increase the security of SCADA networks
Conduct a thorough risk analysis to assess the risk and necessity of each connection to the SCADA network. Develop a comprehensive understanding of all connections to the SCADA network and how well these connections are protected. Identify and evaluate the following types of connections:
To ensure the highest degree of security of SCADA systems, isolate SCADA networks from all other network connections as much as possible. Any additional connections introduce security risks, particularly if connections create a pathway to or from the Internet. Although direct SCADA connections with other networks may allow important information to be passed efficiently and conveniently, insecure connections are simply not worth the risk. ;Isolation of the SCADA network must be a primary goal to provide needed security. Strategies such as utilization of “demilitarized zones” (DMZs) and data warehousing can facilitate the secure transfer of data from the SCADA network to business networks. However, they must be designed and implemented properly to avoid introduction of additional risk through improper configuration.
Conduct penetration and vulnerability testing analyses of any remaining connections to the SCADA network to evaluate the protection posture associated with these pathways. Use this information in conjunction with risk management processes to develop a robust protection strategy for any pathways to the SCADA network. Since the SCADA network is only as secure as its weakest connecting point, it is essential to implement firewalls, intrusion detection systems (IDSs), and other appropriate security measures at each point of entry. Configure firewall rules to prohibit access to and from the SCADA network; be as specific as possible when permitting approved connections. For example, an Independent System Operator (ISO) should not be granted “blanket” network access simply because there is a need for a connection to certain components of the SCADA system. Strategically place IDSs at each entry point to alert security personnel of potential network security breaches. Organization management must understand and accept responsibility for risks associated with any connection to the SCADA network.
SCADA control servers built on commercial or open-source operating systems can be exposed to attacks through default network services. As much as possible, remove or disable unused services and network daemons to reduce the risk of direct attack. This is vital when SCADA networks are interconnected with other networks. Do not permit a service or feature to access a SCADA network unless a thorough risk assessment and benefit analysis shows the benefits of the service/feature far outweigh the potential for vulnerability exploitation. Examples of what services to remove from SCADA networks include: automated meter reading/remote billing systems, email services, and Internet access. An example of a feature to disable is remote maintenance. Secure configuration guidelines, such as the National Security Agency’s series of security guides, for both commercial and open source operating systems, are readily available and easily accessible. Additionally, SCADA vendors are able to help identify secure configurations and coordinate any and all changes to operational systems to ensure removing or disabling services does not cause downtime, interruption of service, or loss of support.
Some SCADA systems use unique, proprietary protocols to communication between field devices and servers. Often the security of SCADA systems is based solely on the secrecy of these protocols. Unfortunately, obscure protocols provide very little “real” security. Do not rely on proprietary protocols or factory default configuration settings to protect your system. Additionally, require vendors to disclose any backdoors or vendor interfaces to your SCADA systems and expect them to provide systems capable of being secured.
Most older SCADA systems (most of the systems currently in use) have no security features whatsoever. SCADA system owners must insist that their system vendors implement adequate security features in the form of product patches or upgrades. Many newer SCADA devices are shipped with basic security features, but these are usually disabled to ensure ease of installation. Analyze each SCADA device to determine whether security features are present. Additionally, factory default security settings (such as in computer network firewalls) are often set to provide maximum usability, but minimal security. Reset all security features to provide the maximum level of security. Only allow settings below maximum security after a thorough risk assessment of the consequences of reducing the security level.
Where backdoors or vendor connections do exist in SCADA systems, strong authentication must be implemented to ensure secure communications. Modems, wireless, and wired networks used for communications and maintenance represent a significant vulnerability to the SCADA network and remote sites. Successful “war dialing” or “war driving” attacks could allow an attacker to bypass all other controls and have direct access to the SCADA network or resources. To minimize the risk of such attacks, disable inbound access to the network and replace it with a callback system.
To effectively respond to cyber attacks, establish an intrusion detection strategy that includes alerting network administrators of malicious network activity originating from internal or external sources. Establishing 24-hour intrusion detection system monitoring is essential;; this capability can be easily set up through a pager. Additionally, incident response procedures must be in place to effectively respond to any attack. To complement network monitoring, enable key logging on all systems and audit the system logs daily to detect suspicious activity as soon as possible.
Technical audits of SCADA devices and networks are critical to ongoing security effectiveness. Many commercial and open-source security tools are available that allow system administrators to conduct audits of their systems/networks to identify active services, patch level, and common vulnerabilities. The use of these tools will not solve systemic problems, but will eliminate the “paths of least resistance” that an attacker could potentially exploit. Analyze identified vulnerabilities to determine their significance; , take corrective actions as appropriate. Track corrective actions and analyze this information to identify trends. Retest systems after corrective actions have been taken to ensure all vulnerabilities were successfully eliminated. Actively scan non-production environments to identify and address potential problems.
Any location with a connection to the SCADA network,, especially unmanned or unguarded remote sites, is a target. Conduct a physical security survey and inventory all access points at each facility with a connection to the SCADA system. Identify and assess all sources of information including remote telephone/computer network/fiber optic cables that could be tapped; radio and microwave links that are exploitable; computer terminals that could be accessed; and wireless local area network access points. Identify and eliminate single points of failure. Site security must be adequate to detect or prevent unauthorized access. Do not allow “live” network access points at remote, unguarded sites simply for convenience.
Establish a “Red Team” to identify potential attack scenarios and evaluate potential system vulnerabilities. Consult a variety of experts who can provide insight into potential weaknesses of the overall network, SCADA systems, physical systems, and security controls. Employees who work on the system every day have great insight into vulnerabilities of your SCADA network and should be consulted when identifying potential attack scenarios and possible consequences. Ensure that insider threats risk are fully evaluated, given that insider sabotage represents one of the greatest threats to an organization. Incorporate “Red Team” evaluation information with risk management processes to assess the information and establish appropriate protection strategies. The following steps focus on management actions to establish an effective cyber security program:
Organizational personnel need to understand specific expectations associated with protecting information technology resources through the definition of clear and logical roles and responsibilities. In addition, key personnel need to be given sufficient authority to carry out their assigned responsibilities. Too often, good cyber security is left up to the initiative of the individual, leading to inconsistent implementations and ineffective security. Establish a cyber security organizational structure that defines roles and responsibilities and clearly identifies how cyber security issues are escalated and who is notified in an emergency
Develop and document a robust information security architecture as part of a process to establish an effective protection strategy. It is essential that organizations design their networks with security in mind and continue to have a strong understanding of their network architecture throughout its lifecycle. Of particular importance, an in-depth understanding of the functions that the systems perform and the sensitivity of the stored information is required. Without this understanding, risks cannot be properly assessed and protection strategies may not be sufficient. Documenting the information security architecture and its components is critical to understanding the overall protection strategy, and identifying single points of failure.
A thorough understanding of the risks to network computing resources from denial-of-service attacks and the vulnerability of sensitive information is essential to an effective cyber security program. Risk assessments form the technical basis of this understanding and are critical to formulating effective strategies to mitigate vulnerabilities and preserve the integrity of computing resources. Initially, perform a baseline risk analysis based on a current threat assessment to use while developing a network protection strategy. Due to rapidly changing technology and the emergence of new threats on a daily basis, an ongoing risk assessment process is also needed so that routine changes can be made to the protection strategy to ensure it remains effective. Fundamental to risk management is the identification of residual risk with a resulting network protection strategy in place and management acceptance of that risk.
A fundamental principle that must be part of any network protection strategy is defense-in-depth. Defense-in-depth must be considered early in the design phase of the development process and must be an integral consideration in all technical decision-making associated with the network. Utilize technical and administrative controls to mitigate threats from identified risks to as much as possible at all levels of the network. Single points of failure must be avoided, and cyber security defense must be layered to limit and contain the impact of any security incidents. Additionally, each layer must be protected against other systems at the same layer. For example, to protect against insider threats, restrict users to access only those resources necessary to perform their job functions.
Organizations and companies need structured security programs with mandated requirements to establish expectations and allow personnel to be held accountable. Formalized policies and procedures are typically used to establish and institutionalize a cyber security program. A formal program is essential for establishing a consistent, standards-based approach to cyber security throughout an organization and eliminates sole dependence on individual initiative. Policies and procedures also inform employees and the consequences of failing to meet those responsibilities. They also provide guidance regarding actions to be taken during a cyber security incident and promote efficient and effective actions during a time of crisis. As part of identifying cyber security requirements, include user agreements and notification and warning banners. Establish requirements to minimize the threat from malicious insiders, including the need for conducting background checks and limiting network privileges to those absolutely necessary.
Configuration Management is a fundamental management process needed to maintain a secure network. Configuration management needs to cover both hardware configurations and software configurations. Changes to hardware or software can easily introduce vulnerabilities that undermine network security. Processes are required to evaluate and control any change to ensure that the network remains secure. Configuration management begins with well-tested and documented security baselines for your various systems.
Robust performance evaluation processes are needed to provide organizations with feedback on the effectiveness of cyber security policy and technical implementation. A sign of a mature organization is one that is able to self identify issues, conduct root cause analyses, and implement effective corrective actions that address individual and systemic problems. Self-assessment processes that are normally part of an effective cyber security program include routine scanning for vulnerabilities, automated auditing of the network, and self-assessments of organizational and individual performance.
Establish a disaster recovery plan that allows for rapid recovery from any emergency (including a cyber attack). System backups are an essential part of any plan and allow for rapid reconstruction of the network. Routinely practice disaster recovery plans to ensure that they are up to date and work and that personnel are familiar with them. Make appropriate changes to disaster recovery plans based on lessons learned.
Effective cyber security performance requires commitment and leadership from senior managers in the organization. It is essential that senior management establish an expectation for strong cyber security and communicate this to their subordinate managers throughout the organization. It is also essential that senior organizational leadership establish a structure for implementation of a cyber security program. This structure will promote consistent implementation and the ability to sustain a strong cyber security program. It is important for individuals to be held accountable for their performance as it relates to cyber security. This includes managers, system administrators, technicians, and users/operators.
Release proprietary data related to the SCADA network only on a strict, need-to-know basis, and only to persons explicitly authorized to receive such information. Never divulge data related to a SCADA network, including the names and contact information about the system operators, administrators, computer operating systems, and/or physical and logical locations of computers and network systems over telephones or to personnel unless they are explicitly authorized to receive such information. Any requests for information by unknown persons need to be sent to a central network security location for verification and fulfillment. People can be a weak link in an otherwise secure network. “Social engineering,” the gathering of information about a computer or computer network via questions to naive users, is often the first step in a malicious attack on computer networks. The more information revealed about a computer or computer network, the more vulnerable the computer/network is. Conduct training and information awareness campaigns to ensure that personnel remain diligent in guarding sensitive network information, particularly their passwords.
