Study Notes
Computer Theory
- Secondary Storage Media: Essential for data retention and management.
- NTFS File System: Key file system for Windows, critical for file structure organization and data recovery.
- File Structure: Defines how data is stored and accessed.
- Data Representation: Key for understanding how data is encoded and processed.
- Windows Registry: Central database for storing configuration settings and options for the operating system and installed applications.
- Encryption and Hashing: Important for data security; involves transforming data into a secure format and verifying data integrity.
- Memory and Paging: Relates to how the OS manages RAM and disk space.
- Questions and Tasks: Encourage review and application of concepts.
Notable Artifacts
- Metadata: Essential information associated with files; can reveal important details about file usage and history.
- EXIF Data: Stores metadata for images, including camera settings and timestamps.
- Prefetch: Helps speed up application loading by storing data related to app execution.
- Shellbags: Records folder access and can provide insights into user activities.
- LNK Files: Shortcut files; can reveal file usage and locations.
- MRU-Stuff: Tracks Most Recently Used items to provide context on user activity.
- Thumbcache: Stores thumbnail images for quick viewing; forensic value in tracking file history.
- Windows Event Viewer: Built-in tool for logging system, security, and application events; vital for forensic investigations.
Decryption and Password Enforcing
- Decryption Attacks: Techniques used to break encryption and access secured data.
- Password Guessing Attacks: Methods used to exploit weak passwords; highlights importance of password strength.
Cybercrime
- Definition: Advanced cybercrime involves sophisticated attacks on computer systems and software; demands technical knowledge.
- Distinction Between Crimes: Cybercrimes involve direct use of computers, while cyber-aided crimes utilize the internet for traditional criminal activities.
- Fraud Model: Cyber fraud involves deceiving victims into surrendering monetary value through online or offline means.
Encryption Techniques
- Asymmetric Key Encryption: Uses a pair of keys (public for encryption, private for decryption); crucial for secure communications.
- Hashing: One-way function for data integrity and secure storage; generates a unique hash value that represents the original data without revealing it.
Ensuring Data Integrity
- Secure Hash Algorithm: Must be collision-resistant and irreversible; critical for password storage and data validation.
- Hashing is widely used in operating systems like Windows to securely store passwords.
Forensic Examination
- Forensic Artifacts: Valuable pieces of information (e.g., documents, communications) critical for investigations.
- Windows Internal Searching: Analyzing system databases helps in mapping artifacts, enhancing evidence recovery.
Windows Event Viewer
- Central tool for logging events within the Windows environment; vital for understanding system usage and detecting anomalies.
- Log Types: Differentiated into application, system, and security logs; includes both successful and failed audit results.
- Logs aid in evaluating application performance and diagnosing issues.
