Segurança cibernética industrial para ambientes de OT
O mundo convergido de TI/OT dos dias de hoje gera mais desafios e novos riscos para a segurança cibernética industrial. Foi-se o tempo em que o "air-gapping" sozinho conseguia manter a segurança do seu ambiente.Today’s sophisticated OT environment is a target for new attacks.
The convergence of IT and OT, and rapid adoption of IoT across both, increases your overall attack surface, as well as attack vectors. Without complete coverage, the likelihood of an attack is not a matter of "if," but "when."

Tome cuidado: A Roadmap for IT/OT Alignment
In your OT environment, your OT devices are increasingly connected, thereby creating new challenges in securing your industrial network. Air-gaps alone are no longer effective. That's because today's industrial attack surface now encompasses both IT and OT, making lateral attacks a growing threat. If an attacker finds a weak link on either side, they can use it as a gateway into your entire organization, quickly gaining access to both information and operations.
Historically, IT staff and systems were independent and isolated from OT staff and systems and vice versa. However, an increasing IT/OT convergence now creates a new source of unacceptable risk for your organization. So what can you do?
An integrated IT/OT security strategy may detect an attack earlier and help your team more effectively identify, investigate and address vulnerabilities and threats across your attack surface.In this white paper, you’ll:
- Learn about how OT and IT are increasingly converging
- Get insight into your expanding attack surface and attack vectors
- Explore issues contributing to a disconnect between IT and OT security practices
- Learn about security and compliance best practices for industrial networks
- See the benefits of a converged IT/OT security strategy
Accidental Convergence: Um guia para operações seguras de TI/OT
Operational technology plays an important role in critical infrastructure and industrial environments. In addition to routers, servers, computers and switches used in traditional IT environments, to operate their plants and factories these industries also use OT devices such as distributed control systems (DCSs), programmable logic controllers (PLCs), and human-machine interfaces (HMIs).
For more than half a century, OT security professionals relied on physically separating these critical OT systems from outside networks to keep them safe. But today, IT and OT environments are increasingly connected. While this brings about a number of benefits for operational efficiencies, this convergence also creates new risks.
While threats that begin in IT can laterally move into your OT environment, OT threats aren’t necessarily the same as those that IT professionals are familiar with addressing. Because of this, you need different security tools and operating policies to secure your OT environment.
In this white paper, you’ll learn more about:
- What’s fueling IT/OT convergence
- Why air-gapping your OT systems is no longer effective
- What accidental convergence is and what can happen
- Threat actors looking to infiltrate your systems
- How you can plan ahead for your security including more visibility, better situational analysis, reduction of cyber risk and more.
Os três principais casos de uso para detecção e gerenciamento automatizados de ativos de OT
When most industrial control systems (ICS) networks were designed and implemented decades ago, cybersecurity was not at the forefront for most organizations. As a result, most ICS networks lack basic security controls and the ability to automatically manage assets like you’d find in more traditional IT environments.
Unfortunately, attackers know this and that’s why ICS networks are increasingly under attack.
As your organization looks for ways to defend your ICS systems, automated asset discovery and automated asset management becomes critical. Por quê? Because if you don’t have an up-to-date and accurate ICS asset inventory, you can’t effectively manage your risks. If you don’t know your risks, how do you secure your environment?
As your ICS network grows and your IT and OT networks continue to evolve, effective asset management will become an increasingly important component of your overall cybersecurity strategy.

Critical Infrastructure Cybersecurity: Actively Secure Your Industrial Environment in the New Era of Distrust
The operational technology environments within industrial and critical infrastructure industries today are larger than ever before. These environments have an increasing number of attack vectors meaning, in many cases, your organization should no longer ask “if” you’ll be subject to attack, but "when".
Within your industrial control system environment, if you’re using network monitoring only, you may miss an attack on a device. That's because network monitoring only gives you about 50% visibility into your converged IT/OT environment. Those blind spots could put you at risk for being infected for days—or even months—without you knowing.
Effective OT cybersecurity needs more than network monitoring. By adding device-based security measures to your program, you’ll have better situational awareness about your actual cyber risks so you can plan remediation and defense strategies accordingly.
Download this white paper to learn more about how you can:
- Improve your controller integrity by quickly discovering device changes made through physical connections
- Discover assets, even those that don’t communicate over your network
- Maintain “last known good state” data so you can enable holistic back-up and recovery strategies
- Monitor all routable components of your network

6 Questions to Ask When Choosing an OT Security Solution
When it’s time to choose an OT cybersecurity solution, you want to know if you’re choosing one that meets all of your organization’s unique and specific requirements and are also forward compatible for future requirements you may have.
To reduce cyber exposure in your OT environment, you should understand if the solution you’re considering will support your specific OT devices, if it can provide non-disruptive asset discovery (even in older network assets), if it will alert on critical vulnerabilities and if it supports secure OT/IT alignment.
Knowing the right questions to ask upfront can prevent future headaches and increase security of your OT and IT environments. Here are seven important questions to consider when evaluating OT cybersecurity solutions:
Is it vendor-agnostic?
The solution should support all of your protocols and specific devices.
Does it provide multi-detection methods?
The solution should provide coverage both to the network as well as to devices on the network.
Does it detect and alert on known common vulnerabilities and exposures?
A platform that incorporates known CVE discovery into your security policy will provide faster detection.
Does it provide IT support in addition to OT?
The solution should work in conjunction with your already deployed IT security products such as your security information event management (SIEM) tool, next-generation firewalls (NGFWs) and diode-based firewalls.
Does it support secure IT/OT alignment?
Each environment needs purpose-made solutions.
Is it designed to live in an OT environment from a hardware or operating environment perspective?
Your solution should be configurable to meet your network and physical architecture requirements.
Tendências que afetam a segurança de OT
Whether intentional or accidental, there are several trends increasing attack surfaces and vectors across OT environments. Let’s take a look at a few and how they can impact your organization:
Purposeful convergence of IT/OT
By uniting IT and OT, your organization may find that eliminating siloed infrastructures can reduce costs and improve operational efficiencies.
Accidental convergence of IT/OT
If your organization doesn’t have a convergence strategy, but your IT assets (such as laptops, thumb drives etc.) are used in OT environments, you can inadvertently create an accidental IT/OT convergence that increases organizational risks.
Industry 4.0 is the newest (and fourth) evolution within manufacturing. It includes the introduction of IoT tech used to monitor and/or control OT environments and/or assets.
With these trends, IT and OT teams are collaborating with each other more than they ever have before. Information and expertise silos are beginning to come down and in some cases IT and OT can function on the same team.
Because today's cybercriminals can attack from all sides—and attacks laterally creep across IT to OT and vice versa—these trends are important to keep an eye on for comprehensive OT security.

While cyberattacks dominate news and industry headlines, not all threats to your operational technology infrastructure comes from external sources. Insider threats can also put your organization at risk. While insider threats can be created from a variety of circumstances, generally they can be classified as malicious intent, human error, or account compromise. So how can you keep your OT environment safe? From risk assessments to monitoring attack vectors and unified IT/OT security, there are some best practice tips you can adopt to keep your attack surface safe.
Cyberattacks in operational technology environments are increasing across many industries, including automotive manufacturing. In the past four years, attacks have increased more than 600%. Por quê? Because changes in OT environments, including increasing convergence with IT, creates new attack vectors and new attack surfaces. For the automotive industry, most OT networks weren’t designed with cybersecurity in mind and attackers are finding ways to infiltrate devices and networks. While the industry faces a number of cybersecurity challenges, you can mitigate your core risks with full OT visibility, security and control.
Verificação inteligente de ICS/SCADA: descubra e avalie sistemas baseados em TI em ambientes convergidos de TI/OT
Today, OT systems are exposed to IT threats, a relatively new risk vector for the industry. That’s because many industrial and critical infrastructure organizations now reap the benefits of having converged IT/OT environments, but doing so creates risks not previously understood and tackled by OT professionals. The solution is not as simple as deploying IT cybersecurity practices into your OT environment. That’s because traditional IT active scanning techniques can easily disrupt your OT environments. Using ICS/SCADA Smart Scanning and passive network monitoring, however, you can discover and assess your IT-based systems in your converged IT/OT environment while reducing the risk that active scanning may disrupt your OT devices.
Industrial control networks create unique challenges for cybersecurity. Traditional IT security strategies don’t often work well in OT environments and OT’s traditional method of air-gapping is no longer an effective defense strategy. These challenges mean an increasing number and wide range of vulnerabilities now create new risks for OT networks. Lack of visibility and control for ICS networks compound the problem and a generalized fear of patching that may cause downtime or disruptions prevails throughout the industry. To overcome the challenges of unsecured OT networks, you should choose a cybersecurity solution that can help you better secure and control your ICS technology.
A Proof of Concept (PoC) is an important resource that can help you determine if an operational technology solution you’re considering is the best option for your organization. In general, there are four phases for a proof of concept, beginning with preparation, then deployment, then execution, then a summary. These stages can help you do a more efficient job in evaluating a cybersecurity solution. At the end of the process you should have a better understanding of a product’s capabilities and limitations, as well as how it should function in your operating environment, and how well your vendor is prepared to work with you now and as future needs arise.
