What is Deepfake, and how does it Affect Cybersecurity?
Producing deepfake is easy. It is hard to detect. They operate with a description of reality rather than reality itself (e.g., a video). Any artifact

The critical infrastructure of a country is what provides the lifeblood to its citizens. It includes everything from power plants, food supply, water systems, and transportation. However, these infrastructures are vulnerable to attack or natural disasters that can lead to loss of life and property. That’s why countries must take steps toward making their critical infrastructures more secure and resilient. Upon completing this article, you will be able to:
Critical infrastructure is the physical and cyber systems that we rely on to provide essential services, such as energy, healthcare, transportation and communications. Such systems are essential to national security and our economy; however, they’re also vulnerable to natural disasters, cyber-attacks and other threats.
Critical infrastructure security and resilience awareness is the need to protect and preserve the essential infrastructures essential to a country’s operation. The critical infrastructures are those that, if disrupted, would have a significant impact on the population’s health, safety, or welfare.
When you hear news stories about critical infrastructure being hacked or compromised by bad actors—like when China was caught penetrating utilities in the US—you might think it’s just another day in cybersecurity. But these stories underscore how important it is for us all to understand what critical infrastructure is and why it matters so much in protecting our personal information online or offline.
Critical infrastructure security and resilience awareness (CISA) is a set of practices to ensure that critical infrastructures are protected from threats and hazards. These threats can come from natural disasters, artificial events, cyber-attacks, or other sources.
CISA helps organizations identify vulnerabilities and risks associated with their critical infrastructure assets and develop strategies for mitigating those risks. Organizations can secure themselves by implementing various strategies like:
The federal government provides funding to protect specific critical infrastructures from cyber threats through its National Infrastructure Protection Plan (NIPP). The NIPP outlines three categories of critical infrastructure:
An attack on critical infrastructure could cause significant harm to people, disrupt the economy or destabilize national security. Critical infrastructure includes physical assets such as transportation and energy systems and cyber-based assets such as the financial sector, healthcare facilities, and government agencies. These systems are vital to national security because they are essential for the daily functioning of our society. When a nation’s critical infrastructure is damaged or destroyed in an attack, it can devastate people’s lives and livelihoods; disrupt economic productivity, or even destabilize national security.
As a nation, we have become increasingly dependent on our critical infrastructure. It’s no longer just the electrical grid or water systems that keep us safe—it’s also telecommunications and even transportation networks. These systems are vital to our way of life, but they’re also vulnerable to physical threats like natural disasters and cyber-attacks.
Someone could hack into a system and use it for their purposes (like stealing data) or shut down entire parts of the network by shutting down computers remotely. In either case, this can cause significant harm to people—think about how many people have been killed or injured in train crashes caused by hackers—or disrupt the economy or destabilize national security (think about what would happen if attackers took control of nuclear power plants).
As we can see, critical infrastructure is a vital part of our everyday lives. So much so that if it were compromised, it could adversely affect national security.
The NIST Cybersecurity Framework is a flexible, repeatable, and cost-effective approach for managing cybersecurity risk. The framework is on a tiered structure that provides organizations with context to decide on appropriate security controls by considering the sensitivity of the information being protected.
The NIST Cybersecurity Framework consists of five components:
This article provides an overview of critical infrastructure, its threats, and measures organizations can take to help protect it. It is planned for anyone who wants to learn more about protecting critical infrastructure systems in their community or organization. The article will help you understand:
