Network Risk Basics

Understanding Network Risks

Network risks represent potential vulnerabilities and threats that can compromise the security, integrity, and performance of computer networks. In the cybersecurity landscape, understanding these risks is crucial for organizations to protect their digital assets.

Types of Network Risks

1. External Threats

External threats originate from outside the network and include:

Malware attacks
Phishing attempts
Distributed Denial of Service (DDoS) attacks

2. Internal Threats

Internal risks emerge from within the organization:

Unauthorized access
Insider attacks
Accidental data leaks

Risk Identification Techniques

Network Scanning

## Basic network scanning using Nmap
sudo nmap -sV 192.168.1.0/24

Vulnerability Assessment

Risk Categorization

Risk Level	Characteristics	Potential Impact
Low	Minimal vulnerability	Minor disruption
Medium	Some security gaps	Moderate damage
High	Significant weaknesses	Severe consequences

Key Risk Indicators

Unusual network traffic patterns
Unauthorized access attempts
Outdated system configurations
Weak authentication mechanisms

LabEx Cybersecurity Approach

Network Traffic Analysis

Analysis Method	Key Features	Detection Capability
Packet Inspection	Deep packet analysis	Detailed threat insights
Behavioral Analysis	Anomaly detection	Unknown threat identification
Signature-based	Known threat matching	Predefined risk detection

Advanced Detection Tools

Wireshark Network Protocol Analyzer

## Install Wireshark
sudo apt-get install wireshark

Real-time Monitoring Script
