Description

As technology continues to advance and systems become more interconnected, the landscape of cybersecurity is evolving just as quickly. Unfortunately, this progress also creates new opportunities for cybercriminals, whose attacks are becoming more effective, damaging, and costly. It seems that hardly a week goes by without headlines announcing massive data breaches, sophisticated hacks, or carefully targeted scams. These incidents raise important questions: How do attackers gain access in the first place, and what can you do to defend yourself, your business, or your organization?

In this course, you will explore some of today’s most common and dangerous cybersecurity threats. From phishing emails designed to trick even the most cautious users, to ransomware that can hold entire systems hostage, to deepfakes that blur the line between truth and deception, the risks are wide-ranging and often unexpected. You’ll also learn about vulnerabilities introduced by unmanaged Internet of Things (IoT) devices and how business email compromise schemes are costing companies millions each year.

Beyond identifying these threats, the course also focuses on practical solutions. You’ll gain an understanding of proven countermeasures and best practices to reduce or even eliminate the impact of cyberattacks. Whether you’re just beginning your cybersecurity journey or working toward a Microsoft Professional Certificate, this course will provide the knowledge and tools to better safeguard digital systems and information.

Who this course is for:

  • Anyone who want to understand the fundamentals of cybersecurity threats and defenses.
  • IT professionals or system administrators seeking to strengthen their security knowledge.
