			3	## What is an Access Control System?
			4
			5	An Access Control System (ACS) is a security solution that regulates and restricts entry to buildings, rooms, or digital systems. These systems are essential for commercial buildings, residential properties, government facilities, and high-security areas to prevent unauthorized access and enhance security.
			6
			7	In the UK, access control systems must comply with specific regulations and standards, ensuring they are legally compliant and effective in securing premises.

			10
			11	## Why Use Access Control Systems in the UK?
			12
			13	### 1. Security & Unauthorized Access Prevention
			14	- Restricts entry to authorized personnel only.
			15	- Reduces the risk of theft, vandalism, and unauthorized access.
			16
			17	### 2. Compliance with UK Security Standards
			18	- Adheres to BS EN 60839-11-1 (electronic access control systems).
			19	- Meets GDPR requirements for biometric and personal data processing.
			20	- Complies with BS 7273-4 (fire door release regulations).
			21
			22	### 3. Audit Trails & Real-Time Monitoring
			23	- Logs entry and exit data for compliance and security auditing.
			24	- Provides real-time alerts and notifications.
			25
			26	### 4. Integration with Other Security Systems
			27	- Works with CCTV, intruder alarms, and fire alarms.
			28	- Enables automated lockdowns during security threats.
			29

			31
			32	## Types of Access Control Systems
			33
			34	### 1. Discretionary Access Control (DAC)
			35	- User-based system where access is granted at the owner’s discretion.
			36	- Common in small businesses and residential properties.
			37
			38	### 2. Mandatory Access Control (MAC)
			39	- Access permissions are strictly regulated by security policies.
			40	- Used in government, military, and high-security industries.
			41
			42	### 3. Role-Based Access Control (RBAC)
			43	- Access is assigned based on job roles and responsibilities.
			44	- Suitable for corporate offices, hospitals, and financial institutions.
			45
			46	### 4. Rule-Based Access Control
			47	- Access is granted or denied based on predefined rules (e.g., time-based access).
			48	- Often combined with RBAC for enhanced security.

			62	## Components of an Access Control System
			63
			64	### 1. Credentials
			65
			66	\| Credential Type \| Description \| Common Uses \|
			67	\|------------------\|---------------\|----------------\|
			68	\| Key Cards & Fobs \| RFID/NFC-based access tokens \| Offices, hotels \|
			69	\| PIN Codes \| Numeric entry via keypad \| Secure rooms, safes \|
			70	\| Biometric Scanners \| Fingerprint, retina, or facial recognition \| High-security facilities \|
			71	\| Mobile Access \| Smartphone-based authentication \| Smart locks, modern offices \|
			72
			73	### 2. Readers & Scanners
			74
			75	\| Device \| Function \|
			76	\|------------\|-----------------\|
			77	\| RFID/NFC Readers \| Reads keycards or fobs for access authentication. \|
			78	\| Keypad \| Accepts PIN codes for entry verification. \|
			79	\| Biometric Scanner \| Uses fingerprints, facial recognition, or iris scanning. \|
			80
			81	### 3. Access Control Panels & Controllers
			82	- Acts as the central hub managing authentication data.
			83	- Sends signals to unlock doors or deny access.
			84	- Can integrate with alarms and security monitoring systems.
			85
			86	### 4. Locks & Door Hardware
			87
			88	\| Lock Type \| Function \|
			89	\|------------\|------------\|
			90	\| Magnetic Lock (Maglock) \| Uses electromagnets to secure doors. \|
			91	\| Electric Strike Lock \| Releases upon authentication for door access. \|
			92	\| Smart Lock \| Keyless entry with mobile or biometric access. \|
			93
			94	### 5. Management Software
			95	- Admins use software to manage users, credentials, and security policies.
			96	- Can be on-premises or cloud-based for remote management.
			97

			100	## Authentication Methods
			101
			102	\| Authentication Type \| Description \| Security Level \|
			103	\|-----------------\|-------------------\|----------------\|
			104	\| Single-Factor Authentication (SFA) \| Uses one method (e.g., keycard) \| Moderate \|
			105	\| Two-Factor Authentication (2FA) \| Combines two methods (e.g., keycard + PIN) \| High \|
			106	\| Multi-Factor Authentication (MFA) \| Uses multiple layers (e.g., fingerprint + PIN + keycard) \| Very High \|
