SWGDE - Answer Based on the SWGDE work to create the set of standards for
gathering of digital evidence.
• Criteria 1.1 - All agencies that seize and/or examine digital evidence must maintain an
appropriate SOP document
• Criteria 1.2 - Agency management must review the SOPs annually
• Criteria 1.3 - Procedures used must be generally accepted in the field
• Criteria 1.4 - The agency must maintain written copies of appropriate technical
procedures
• Criteria 1.5 - The agency must use hardware and software that is appropriate and
effective
• Criteria 1.6 - All activities must be recorded in writing and be available for review and
testimony
• Criteria 1.7 - Any action that has the potential to alter, damage, or destroy any aspect
of original evidence must be performed by qualified persons in a forensically sound
manner
Cloud Crime - Answer *Cloud as a subject It refers to a crime in which the attackers try
to compromise the security of a cloud environment to steal data or inject a malware. Ex:
Identity theft of cloud user's accounts, unauthorized modification or deletion of data
stored in the Cloud, installation of malware on the cloud, etc.
,*Cloud as an object when the attacker uses the cloud to commit a crime targeted
towards the CSP. The main aim of the attacker is to impact cloud service provider. Ex:
DDoS attacks that can bring the whole cloud down.
*Cloud as a tool when the attacker uses one compromised cloud account to attack other
accounts. In such cases, both the source and target cloud can store the evidence data.

The UEFI boot process has five phases and each phase has its own role. These five
phases are: - Answer SEC (Security) Phase This phase of EFI consists of initialization
code that the system executes after powering the EFI system on. It manages platform
reset events and sets the system so that it can find, validate, install, and run the PEI.
PEI (Pre-EFI Initialization) Phase The PEI phase initializes the CPU, temporary
memory, and boot firmware volume (BFV). It locates and executes the Pre Initialization
chapters (PEIMs) present in the BFV so as to initialize all the found hardware in the
system. Finally, it creates a Hand-Off Block List with all found resources interface
descriptors and passes it to the next phase i.e. the DXE phase.
DXE (Driver Execution Environment) Phase Most of the initialization happens in this
phase. Using the Hand-Off Block List (HOBL), it initializes the entire system physical
memory, I/O, and MIMO (Memory Mapped Input Output) resources and finally begins
dispatching DXE Drivers present in the system Firmware Volumes (given in the HOBL).
The DXE core produces a set of EFI Boot Services and EFI Runtime Services. The EFI
Boot Services provided are allocating memory and loading executable images. The EFI
Runtime services provided are converting memory addresses from physical to virtual
,while handing over to the kernel, and resetting the CPU, to code running within the EFI
environment or within the OS kernel once the CPU takes the control of the system.
BDS (Boot Device Selection) Phase In this phase, the BDS interprets the boot
configuration data and selects the Boot Policy for later implementation. This phase
works with the DXE to check if the device drivers require signature verification. In this
phase, the system loads MBR boot code into memory for Legacy BIOS Boot or loads
the Bootloader program from the EFI partition for UEFI Boot. It also provides an option
for the user to choose EFI Shell or an UEFI application as the Boot Device from the
Setup.
RT (Run Time) Phase At this point, the system clears the UEFI program from memory
and transfers it to the OS. During UEFI BIOS update the OS calls the run time service
using a small part of the memory.

Superblock holds the following information: - Answer Magic Number: It allows the
mounting software to verify the Superblock for the EXT2 file system. For the present
EXT2 version, it is 0xEF53. •
Revision Level: The major and minor revision levels allow the mounting code to
determine whether or not this file system supports features that are only available in
particular revisions of the file system. There are also feature compatibility fields that
help the mounting code to determine which new features can safely be used on this file
system. •
Mount Count and Maximum Mount Count: Together these allow the system to
determine if it needs to fully check the file system. The mount count increments each
time the system mounts the file system and displays the warning message of "maximal
mount count reached, running e2fsck is recommended'' when it equals the maximum
mount count
