6. Identity and Access Management (IAM): IAM is concerned with managing user identities and regulating access to digital resources.
7. Internet of Things (IoT) Security: This realm safeguards IoT devices, preventing them from being compromised and used as entry points for cyberattacks.

Practical Application of Cybersecurity

Cybersecurity finds application across diverse sectors and in various capacities:

• Corporate Security: It safeguards business operations, customer data, and intellectual property.
• Government and National Security: It’s crucial for protecting critical infrastructure and sensitive government information.
• Individuals: It’s indispensable for securing personal data, online accounts, and financial information.
• Healthcare: It’s essential in safeguarding patient records and medical devices.
• Financial Institutions: It’s pivotal for securing transactions, client data, and online banking services.

Illustrating Cybersecurity in Practice

Imagine an online retailer that stores customer payment information. Effective cybersecurity measures would encompass robust encryption to safeguard this sensitive data from unauthorized access. Additionally, regular security audits and updates would be in place to promptly address vulnerabilities as they emerge.

The Primary Role of Cybersecurity

At its core, the primary role of cybersecurity revolves around risk management and asset protection. It encompasses:

1. Risk Assessment: Identifying potential threats and vulnerabilities.
2. Prevention: Implementing measures to proactively thwart security breaches.
3. Detection: Swiftly recognizing breaches when they occur.
4. Response: Taking decisive actions to contain and mitigate the impact of security incidents.
5. Recovery: Restoring normalcy and assessing lessons learned following an incident.

Navigating the 7 Layers of Cybersecurity

The realm of cybersecurity operates across multiple layers, often referred to as:
