Study Notes
Linux Forensic Tools
-
topcommand is used to find running processes and displays results sorted by CPU usage, showing process ID, time, and executed command. -
pscommand is used to provide information on current running processes, including ID, CPU usage, memory usage, and other details. - Variations of
pscommand:-
ps axto get a full list of running processes -
ps -efto get more detailed information -
ps –U userto find other system users' running processes -
ps –C program_nameto find the history of a particular program -
ps -Ato view all processes -
ps rto view only running processes
-
Fport Tool
- Fport is a forensic tool used to find open TCP/IP and UDP ports and the applications listening on those ports.
- The tool helps investigators map ports to running processes and document the process identification number and path.
- Fport can be downloaded from the McAfee website.
Modes of Attack
- Cyber-attacks can be divided into two types: internal (insider) attacks and external (outsider) attacks.
- Examples of cyber-crimes include financial frauds, laptop or device theft, insider internet abuse, data theft, unauthorized access, viruses, worms, and backdoor attacks, and denial of service attacks.
Computer Forensics
- Computer forensics and digital investigation involve identifying and investigating cyber-crimes.
- The systematic approach to investigation involves a standard guideline and steps to follow.
- The process includes initiating and performing the investigation, legal laws and boundaries, techniques to gather evidence, and the scope of forensic work.
Volatile Data
- Volatile data is stored in system memory and is lost when the machine loses power or is shut down.
- Persistent data, on the other hand, is stored in nonvolatile storage devices and is not lost after rebooting or shutting down the machine.
- It is essential to differentiate between persistent and volatile data and prioritize collecting volatile data first.
Computer Forensics Team
- Law enforcement and security agencies are responsible for investigating computer crimes, but organizations should also have the capability to investigate basic issues themselves.
- Organizations can hire experts from small or mid-size computer investigation firms or create their own computer forensic services firm with a forensics lab, necessary permissions, and the right tools and people.
