Module 1 - Intro to Internet and Cloud Forensics Flashcards

Define cloud-computing Explain differences in current cloud-computing models Compare and contrast different forms of virtualization, including full virtualization, paravirtualization, and hardware assisted virtualization.

1
Q

Traditional Computer Forensics vs Network

A

Dead analysis of media:

  • media that contains user files and system artifacts
  • exam of hard drives, disk arrays, external storage with write blockers and forensic software

Expanding to include:

  • memory analysis
  • live analysis
  • behavioral analysis of malware

Network Exam
- analysis of network traffic as observed by firewalls, IDS, and packet captures (PCAP) from network forensic devices.

Q

issues in cloud computing for traditional forensics (2)

A
  • no direct access to media

- access to deleted files is difficult or impossible

Definition of Cloud Computing (3)

A

Main characteristics: dynamic assignment of hosted resources

TechTarget: - general term for anything that involves delivering hosted services over the Internet
NIST - model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

Q

Four (4) Models of SaaS

A

Custom - each user has own application
Configurable - users separate their instances from each other
Configurable, multitenant-efficient - single application to serve all users/customers
Scalable, configurable, multitenant-efficient - same as above with added load-balancing.

Q

Characteristics of Virtual Machine Monitor (3)

A

E.g. Hypervisor

  • environment for programs nearly identical to physical computer
  • programs have little speed degradation
  • total control of system resources
17
Q

Full Virtualization

A
  • VME completely simulates underlying hardware
  • Multiple guest OS run simultaneously
  • Binary translation and direct execution

Example: VMware workstation, parallels, virtualbox, Hyper-v

18
Q

Paravirtualization

A
  • modifying OS kernel
  • Nonvirtualizable instructions replaced with hypercalls

Examples: KVM

19
Q

Hardware virtualization

A

privileged and sensitive calls are automatically set to trap to the hypervisor.

20
Q

Load Balanced Applications

A

Web application server traffic distributed based on:

  • Round-robin
  • low-utilized resources gets next request
  • priority to a given server, if it is available
