Question 21: Differentiate between active and passive security attacks.

Solution:
Passive security attack: In this attack the intruder or attacker just sniffs the information, he does not modify or change it. He only listens to the traffic and compromises the confidentiality of the data

Active Security attack: In this the attacker first listens to the information and then changes it and then forwards it to the receiving party which means the confidentiality and integrity both compromises.

SPF makes use of a TXT DNS resource log in which the sending domain identifies all of the domain's senders. To authenticate the sender, the receiver will query a TXT DNS resource record about the sender's address domain and IP address. DKIM, on the other hand, uses a digital signature. The sender's private key will be used to sign the message. The receiver would then search the public key to see if the message is from the legitimate sender

 Question 7:  Forensics acquisition can be done in static and live modes.
a) Describe the concept of live acquisition in digital forensics.
b)  Discuss TWO (2) cases in which live acquisition should be considered in finding potential crime evidence.

Solution:
A-The acquisition of live device is manily of concern to digital investigator and incident responds,
Who must normally follow protocols and policies that produce forensically sound duplicates.
When gathering data from a live device for analysis,we are most concerned with volatile data,which is irretievable until the system is turned off.
In an ideal process each stage of the acquired by previous stage.
Its difficult to find optimal procedures however we should try .
Computer data is classified intp two types:Volatile data and permanent data.
When computer is turned off All volatile data is lost changed or made unavaliable.
Anything else is premanent data can be accessed even after the power is turned off.
The passing of time or the acquisition process itself can further alter volatile data .
Ram is the best example of data volatile because loses it contants very easily after machine is turned off.

B-some of the cases in which the The live acquisition is good that when the user who committed the crime has a device running and there has been crime committed fairly recently and evidence can be flound in the ram.
Another case could be when the device is password protected and the criminal is not cooerative than the ram can give hints about the password and sometimes password information for the true cryot and other encryption programs can be found in Ram.

 Question 8: In an event of a forensics investigation, Windows Event Logs serve as the primary source of evidence as the operating system logs every system's activities. Explain how Windows Event Logs can help in forensics investigation and list TWO (2) types of events that are recorded in Windows event logs.

Solution:
Based on the logging details and the discoverd objects, windows event log revuew will assist an investigator in creating timeline.
The windows case logs assist in reconstructiong the sequence of events to aid in an investigation.
any incident that has an impact on the system may be registered as an event:
<Incorrect login attempt><Hack breach>
<system settings change><application failure>
<system failure and so on.

consider the following scenario:
A hacher attempts to remptely break into the device, first the hacker can brute force the system and those logs would be found in security when the user is successful in breaking into the device.
another log is created in protection excepts IP address which may aid in the investigation.

Question 15: A 2017 story from Digital Forensics Magazine describes a hit-and-run car crash caused by the driver of a dark SUV without lights on. The SUV hit a car, ran into a clump of trees and then drove off. Police were able to locate an SUV that fit the description. After downloading data from its on-board diagnostics, infotainment and telematics systems, police were able to determine that the vehicle had passed the scene at the approximate time the crash had occurred, that the lights had not been on and that the SUV had been placed in reverse and forward several times immediately after the time of the crash in the proximity of the damaged trees.
