Study Notes
IP Spoofing
- A technique where a malicious actor disguises their IP address to appear as a trusted source
- The primary concern is that it allows attackers to gain unauthorized access to systems or networks
Packet Interception
- The act of capturing network packets as they travel between devices
- The purpose is to monitor or intercept communication, potentially for security purposes, but also for malicious activities
Authentication in Computer Networks
- The process of verifying the identity of a user or device before granting access to a network or system
- Enables secure communication and protects against unauthorized access
Denial of Service (DoS) Attack
- An attack that aims to make a computer system or network unavailable to legitimate users by overwhelming it with traffic
- The primary challenge is to distinguish legitimate traffic from malicious traffic effectively
Authentication in Cellular Networks
- The process of verifying the identity of a mobile device and user before allowing access to the cellular network
- Its purpose is to ensure secure communication, prevent unauthorized access, and protect user privacy
Packet Interception in Network Security
- Used for security monitoring and analysis, to detect and prevent malicious activity
- It can also be used for lawful interception, such as for legal investigations
Role of Authentication in Cellular Networks Regarding User Privacy
- Helps protect user data from unauthorized access
- Provides user identification for billing and service management purposes
Primary Defense Against IP Spoofing Attacks
- Implementing authentication mechanisms that verify the identity of the sender
### Primary Concern With IP Spoofing Attacks
- Enables attackers to bypass security measures, gain unauthorized access, and potentially carry out other malicious attacks
