Networking and Internet Security Functions

Introduction

This page provides a brief overview of key functions and concepts within the Networking and Internet Security domain. Understanding these is critical for secure network design and implementation.

Security Functions

This section details several fundamental security functions:

• Key Management: Securely generate, store, and manage cryptographic keys for authentication and encryption.
• Authentication & Authorization: Implement robust authentication protocols (e.g., OAuth 2.0, SAML) to verify user identity and control access based on roles and permissions.
• Encryption: Utilize symmetric and asymmetric encryption algorithms to protect sensitive data in transit and at rest.
• Firewall Management: Configure and manage firewalls to filter network traffic and prevent unauthorized access.
• Intrusion Detection: Implement intrusion detection systems (IDS) to identify and respond to malicious activity.
• Vulnerability Scanning: Regularly scan systems for known vulnerabilities using automated tools.

Functions Overview

Function 1: Reverse DNS Lookup: Used to determine the IP address associated with a hostname.

Function 2: SSL/TLS Configuration: Establish secure connections over networks using encryption and authentication.

Function 3: IP Address Spoofing Detection: Identify and prevent attempts to manipulate IP addresses.

Function 4: VPN Configuration: Establish secure tunnels for data transmission over public networks.

Function 5: Certificate Management: Securely generate, store, and manage digital certificates for server authentication.
