Cybersecurity and digital forensics are instrumental in creating efficient protection, evaluation and investigation of cybercrime. Whereas each give attention to the safety of digital property, they arrive at it from two totally different angles.
Digital forensics offers with the aftermath of the incident in an investigatory function, whereas, cybersecurity is extra targeted on the prevention and detection of assaults and the design of safe programs.
Consider the cybersecurity professional because the frontline police officer and the SWAT response group multi functional. The digital forensics professional is the specialist investigator that hunts the perpetrator and seeks to grasp their motivations.
Let’s see how the 2 practices complement one another to cease malicious assaults and monitor down the criminals concerned.
What Does a Digital Forensics Skilled Do?
The follow of digital forensics contains the gathering, examination, evaluation and reporting of incidents involving, laptop, community and cellular units. Digital forensics professionals work throughout each the private and non-private sectors, and their function normally entails:
- Conducting knowledge and safety breach investigations;
- Recovering and analyzing knowledge from computer systems and digital storage units;
- Dismantling and rebuilding broken programs to retrieve misplaced knowledge;
- Figuring out further programs compromised by cyberattacks and compiling proof for authorized circumstances.
The top aim of a digital-forensics investigator is to determine the perpetrator of a cybercrime, acquire arduous proof in opposition to the perpetrator, and for that proof to be admissible in a court docket of legislation.
Case Examine: Digital Forensics Helps Clear up Cyber Espionage
In 2008, the worst cyberattack in US navy historical past noticed an unprecedented quantity of labeled navy knowledge to fall into overseas palms. Unprepared for an assault that originated inside their very own community, the Pentagon deployed digital forensics investigators to find out the supply of the assault and the way the breach occurred.
Their investigative work pinpointed the breach to a US navy base within the Center East. The trigger was a USB flash drive inserted by considered one of their very own personnel contained in the navy’s laptop community — thus bypassing the entire safety countermeasures their cybersecurity group had constructed (e.g. firewalls).
Additional investigation discovered that the person was not a double agent working throughout the US Navy, however a naive staffer who thought that they had discovered a free flash drive. That they had unsuspectingly picked it up in a carpark exterior the navy base, the place lots of of flash drives containing the malware had been scattered. The cybercriminal who planted them solely wanted one unsuspecting individual to select one up and apply it to their laptop.
Cyber-forensic professionals — working with cybersecurity consultants — performed a vital function in figuring out the supply of the breach and in-turn, placing measures in place to make sure such a breach doesn’t happen once more.
The work of a cyber-forensic skilled can result in individuals and locations exterior of the digital realm. This assault modified the complete course of the US navy technique in direction of cybersecurity and cyberwarfare, leading to a brand new division of cybersecurity professionals and forensic investigators being created to defend, assault and hunt cybercriminals.
Digital Forensics and Cybersecurity in Motion
Within the wake of the drone scare at Gatwick airport within the UK, cybersecurity college students at Edith Cowan College have been creating a system that robotically tracks and disables rogue drones, whereas additionally monitoring down their house owners. The internship program, named Spectrum Watch, can isolate knowledge visitors being despatched to the drone. This implies cybersecurity brokers can take management of the drone, decreasing its descent and minimising the risk it presents. By preserving the drone — versus merely destroying it — digital forensics investigators can analyze it and extract details about the drone’s origin, flight path and entry any pictures or video recorded by the drone.
In case you are occupied with a difficult profession in cybersecurity, you may examine on-line and acquire your Masters in Cyber Safety from Edith Cowan College, learning digital forensics as a core unit of your diploma.
