1.1. What is Cyber Security?

Today, we are going to delve into what we mean by cyber security. Can anyone tell me what they think cyber security is?

Isn't it about protecting computers and the internet from hackers?

That's a great start! Cyber security indeed focuses on protecting systems, networks, and data from digital attacks. These attacks may aim to access, alter, harm, or destroy sensitive information. A simple way to remember this is through the acronym 'PADS'—Protecting Assets, Data, and Systems.

What types of attacks are we talking about exactly?

Good question! Attacks can vary widely but often include data breaches, ransomware, and worse. Each of these attacks has the potential to disrupt normal business functions.

So, cyber security is really important!

Absolutely! We live in a digital world, making the role of cyber security vital to safeguard not just data but trust and financial stability as well. Remember, cyber security protects critical infrastructure, which has national security implications.

How do we implement these security measures?

We'll cover different domains of cyber security, like Network Security and Application Security, shortly.

To wrap up this session, remember: Cyber security is about safeguarding systems from harm. Think of the 'PADS' to recall its essential focus areas.

Let’s talk about why cyber security is so crucial today. Can anyone give me an example of what can go wrong without proper cyber security?

We could lose our personal information, like passwords or banking details!

Exactly! Protecting sensitive information is one of the critical reasons we need cyber security. It ensures our data remains private and secure. How about financial impacts?

Companies can lose a lot of money due to cyber attacks!

Right again! Cyber crimes can lead to significant financial losses. Also, can anyone think of how cyber security helps businesses maintain trust?

If companies handle data responsibly, customers feel more secure sharing their info!

Exactly! Trust is a cornerstone of business, and good cyber security practices are essential to maintaining that. And lastly, remember that cyber security also has national implications, safeguarding critical infrastructure. Think of it like a digital shield we must uphold!

As a recap, cyber security is essential to protect sensitive information, ensure privacy, prevent financial loss, and maintain public trust.

Now, let’s dive into some key concepts to better understand cyber security. What do you think a 'threat' is?

Is it something that could cause harm?

Exactly! A threat is a potential cause of unwanted incidents, like malware trying to steal passwords. Now, what’s a 'vulnerability'?

It’s a weakness in a system that can be exploited by a threat!

Correct! And together, threats and vulnerabilities lead us to 'risk.' What’s the formula for assessing risk?

Risk equals Threat times Vulnerability times Impact!

You got it! Remembering that formula is crucial for evaluating the potential impact of cyber attacks. Before we finish, can anyone tell me why understanding these concepts is important?

It helps us know how to protect our systems better!

Exactly! Understanding threats, vulnerabilities, and risks equips us to create effective strategies to enhance our cyber security posture.

In summary, threats are potential harms, vulnerabilities are weaknesses, and risk is the combination of the first two. Keep those concepts in mind as we move forward!
