ANSWER
Cyber security refers to the practices, technologies, and processes designed to protect computers, networks, programs, and data from unauthorized access, attacks, or damage. In today’s digital age, nearly everyone relies on the internet for daily activities such as shopping, banking, socializing, and more. As our personal, financial, and professional lives become increasingly intertwined with digital technologies, the potential risks and impacts of cyber threats also increase. Effective cyber security helps protect not only individual privacy but also the stability and security of society as a whole.
Here’s why cybersecurity is important for Society:
Protecting Personal Information: As we live more of our lives online, from social media to banking, our personal information is at risk. Cyber security measures help protect this information from unauthorized access and theft.
Safeguarding National Security: Governments store a vast amount of data, from confidential national security information to personal records of citizens. Cyber attacks on these systems can lead to national security threats.
Ensuring Business Continuity: Businesses rely heavily on digital processes. Cyber attacks can disrupt these processes, leading to significant financial and reputational damage.
Protecting Infrastructure: Much of our critical infrastructure, including power grids and water systems, is managed online. Cyber security helps protect these systems from attacks that could lead to widespread societal disruption.
How It Works
Cyber security works through a layered defense mechanism:
Physical Security: Protecting physical access to hardware and devices.
Network Security: Securing data as it transits networks through encryption and firewalls.
Application Security: Ensuring that applications are secure and cannot be exploited to gain unauthorized access to underlying systems.
Endpoint Security: Protecting end-user devices like computers and mobile phones.
Data Security: Ensuring that data, both at rest and in transit, is encrypted and securely stored.
Identity Management: Controlling access to information and monitoring activities to ensure that only authorized users can access sensitive data.
Disaster Recovery/Business Continuity Planning: Ensuring that the business can continue to operate in the event of a major cyber incident and that data can be restored.

Analogy
To fully understand the importance and functionality of cyber security, let’s imagine it as a medieval castle — a structure designed to protect its inhabitants from outside threats.
The Castle’s Structure: Layered Defense
Outer Walls (Network Security): Just as a castle has high walls to fend off invaders, network security serves as the first line of defense, keeping unauthorized users out of the network. These walls are reinforced with firewalls and intrusion detection systems that act like archers on the walls, spotting and repelling intruders.
Moat (Perimeter Security): Surrounding the castle is a wide moat, which can be likened to perimeter security measures such as border gateways and email security gates that prevent attacks from reaching the network.
Drawbridge (Access Control): The drawbridge is the point of controlled access into the castle, similar to identity and access management in cyber security, ensuring that only those who are verified can enter.
Guarded Treasury (Data Security): Inside the castle, the treasury where valuable assets are stored is heavily guarded. In cyber security, sensitive data is protected through encryption, akin to the secure vaults within the castle.
Lookouts (Threat Detection): High towers enable lookouts to see threats from afar, similar to the role of threat detection in cyber security, which uses predictive analytics to identify potential threats before they reach the castle.
Armed Guards (Endpoint Security): Armed guards protect the castle’s inhabitants by securing entry points and critical areas, much like endpoint security ensures that entry points for data on devices are fortified against attack.
Emergency Protocols (Disaster Recovery): In case the castle is breached, there are emergency protocols to secure the royal family and important assets, similar to disaster recovery in IT, where plans are in place to recover data and restore systems as quickly as possible.
This analogy helps visualize the complex nature of cyber security, emphasizing the importance of each layer of protection in safeguarding valuable assets from the multitude of threats that exist in our increasingly digital world. By understanding these layers and their functions, one can appreciate the robust, interdependent system that is necessary to defend against sophisticated digital attacks.
