Study Notes

Mobile Forensic Techniques Overview

Analyzing mobile devices provides valuable information for law enforcement and intelligence agencies.
Mobile forensics focuses on recovering digital evidence from mobile devices, unlike traditional forensics.
Useful information includes text messages, web search history, and location data.

Mobile Device Platforms and Types

Mobile devices range from smartphones to tablets and smart wearables.
Different operating systems exist, with specific features and capabilities depending on the device type.
Types of mobile applications:
- Mobile Web Apps: Accessed through a web browser.
- Native Apps: Platform-specific; optimal performance with UI tailored to the OS.
- Hybrid Apps: Combination of web and native features; generally more cost-effective for cross-platform development.

Mobile App Development Insights

Native Apps offer the best user experience but incur high development and maintenance costs.
Hybrid Apps are cheaper and easier to maintain but may sacrifice performance and graphics quality.

Mobile Device Characteristics

Designed for portability and ease of use, mobile devices offer functionalities similar to PCs.
They include compact designs, battery-powered operation, and non-volatile memory types.

Memory Considerations in Mobile Devices

Mobile devices primarily use NAND and NOR flash memory.
- NAND Flash: Offers higher storage capacity, sequential access, less stable.
- NOR Flash: Faster read times, better for code execution, allows random access.
Evolution of memory:
- First Generation: Feature phones with NOR flash and RAM.
- Second Generation: Smartphones combining NOR, NAND, and RAM.
- Third Generation: Modern smartphones using only NAND and RAM for efficiency.

RAM and User Identity Module Characteristics

RAM captures are challenging due to volatility; valuable information often resides in this memory.
User Identity Module (UIM) authenticates device users to networks and stores personal information.

Cellular Network Types and Characteristics

Dominant digital cellular networks include:
- CDMA (Code Division Multiple Access): Uses spread spectrum technology, allows multiple calls via unique codes.
- GSM (Global System for Mobile Communications): Primarily TDMA; widely used and designed for efficient communication.
Other networks include TDMA and iDEN, each utilizing unique methods for data transmission and access.
Digital AMPS (D-AMPS) is a digital version of the original analog cellular service standard.

Key Technologies

CDMA offers advantages in bandwidth usage, facilitating multiple concurrent calls.
TDMA allows shared access to channels, enhancing communication efficiency with time allocation.
