Proper identity management reduces unauthorized access.

Multi-Factor Authentication

Multi-factor authentication strengthens account security by requiring more than one verification method.

Verification methods may include:

• Passwords
• Security codes
• Authentication applications
• Hardware security devices
• Biometric verification

Multiple authentication factors improve account protection.

Access Control

Access control limits user permissions according to organizational requirements.

Examples include:

• Administrator access
• Department-based permissions
• Temporary access
• Read-only access
• Privileged accounts

Controlled access reduces unnecessary exposure.

Network Security

Network security technologies protect communication systems from cyber threats.

Common technologies include:

• Firewalls
• Intrusion detection systems
• Secure gateways
• Network segmentation
• Virtual private networks

Network protection supports secure digital communication.

Endpoint Security
