A layered defense strategy is crucial for building a strong and resilient security posture. Here is a breakdown of the core components within a typical security framework, with scientific correction and detailed explanations for each element:
/
├── Security Architecture/ // The security architecture: The foundational strategy and system design
│ ├── Network Security/ // Network Security: Protecting entry points to the network
│ │ └── Firewalls // Firewall: Applies specific rules to allow or block data traffic between different networks, acting as a primary defense point.
│ │ └── IDS/IPS // Intrusion Detection/Prevention System: An IDS monitors network traffic for suspicious activity and issues alerts, while an IPS automatically blocks detected attacks before they reach their target.
│ │ └── VPN // Virtual Private Network: Creates a secure, encrypted "tunnel" over a public network to ensure data confidentiality during remote access.
│ ├── Endpoint Security/ // Endpoint Security: Protecting individual devices connected to the network
│ │ └── Anti-Virus Software // Anti-Virus Software: Detects, prevents, and removes malware such as viruses, trojans, and ransomware.
│ │ └── EDR (Endpoint Detection & Response) // Endpoint Detection & Response System: Continuously monitors device activity to detect advanced threats and collects data to facilitate quick investigation and response.
│ │ └── Patch Management // Patch Management: A systematic process for managing and distributing security updates for software and operating systems to fix known vulnerabilities.
│ ├── IAM/ // Identity and Access Management: A set of policies and processes that control user access to resources
│ │ └── Multi-Factor Authentication (MFA) // Multi-Factor Authentication: Requires a user to provide two or more verification factors to prove their identity, such as a password and a code sent to their phone.
│ │ └── Role-Based Access Control (RBAC) // Role-Based Access Control: Grants users specific access permissions based on their job roles to ensure the principle of least privilege.
│ └── Data Security/ // Data Security: Protecting the confidentiality, integrity, and availability of data
│ │ └── Encryption // Encryption: The process of converting data into an unreadable format (ciphertext) so it cannot be understood without the correct decryption key.
│ │ └── DLP (Data Loss Prevention) // Data Loss Prevention: Monitors and controls sensitive data to prevent it from being lost or leaked outside the network.
│ │ └── Backup and Recovery // Backup and Recovery: The process of creating copies of data to ensure it can be quickly restored in case of loss or damage.
│ └── Monitoring & Response/ // Monitoring and Response: Continuous threat detection and incident handling
│ │ └── SIEM (Security Information & Event Management) // Security Information & Event Management: A system that collects and analyzes data from multiple sources in real time to detect threats.
│ │ └── Threat Intelligence // Threat Intelligence: Provides information and context about potential and new security threats to help organizations make proactive defensive decisions.
│ │ └── Incident Response Plan // Incident Response Plan: A detailed document outlining the steps and procedures to be taken before, during, and after a security incident.
└── Policies & Procedures/ // Policies and Procedures: The human element and operational guidelines
└── Training & Awareness // Training and Awareness: Educational programs designed to inform employees about security best practices, making them the first line of defense.

└── eslintrc.cjs // ESLint configuration
└── astro.config.mjs // Astro configuration
└── tailwind.config.mjs // Tailwind configuration
└── tsconfig.json // Typescript configuration
└── package.json // All the installed packages
