Introduction to Cybersecurity

The cyberattack juggernaut increased impossibly in 2024 and left its victims more devastated than ever. Last year, companies were the victims of some nasty attacks. For instance, the British Library ransomware attack cost them approximately £7m.

Unfortunately, this is the reality of our digital world right now. Cybersecurity has become a must-have defense for organizations these days. But here’s the good news: by understanding the fundamentals of cybersecurity, you can protect yourself and your organization against these threats.

Let’s explore what cybersecurity entails, its scope, and how you can step into this high-demand field.

What Does Cybersecurity Mean?

Cybersecurity refers to the practice of safeguarding systems, networks, and data from cyber threats, including unauthorized access, theft, or destruction. It protects sensitive information like:

• • Financial data

• • Intellectual property

• • Personal records (that can cause financial loss)

• • Reputational damage

• • Operational disruption and more

For instance, a Russian-based hacking outfit attacked Microsoft’s systems. They attacked their passwords and used those to access corporate accounts belonging to the C-suite employees. This incident highlighted the importance of robust identity management and advanced detection measures to protect critical infrastructure.

Scope of Cybersecurity

In the first quarter alone of 2024, over $12.5 billion in cyberattacks were reported. The scope of cybersecurity in 2025 is also complex, driven by factors such as technological advancements, geopolitical instability, and interconnected global supply chains.

Organizations face growing vulnerabilities, with 54% identifying supply chain interdependencies as a key barrier to achieving resilience. The adoption of AI further complicates the landscape; while 66% of businesses anticipate AI’s transformative impact, only 37% have robust processes to secure AI tools, creating significant risks.

Geopolitical tensions amplify concerns over cyber espionage, intellectual property theft, and operational disruptions, with one-third of CEOs ranking these as critical threats.

Meanwhile, cybercriminals leverage sophisticated tools like generative AI to scale disinformation campaigns and ransomware attacks. Additionally, regulatory fragmentation and an expanding cyber skills gap—up by 8% since 2024—exacerbate the challenges.
