DFIR - Digital Forensic And Incident Response 

Digital forensics and incident response (DFIR) is a specialized field focused on identifying, remediating, and investigating cybersecurity incidents. As the name suggests, DFIR consists of two related components: Digital forensics involves collecting, preserving, and analyzing forensic evidence.

Digital forensics and incident response (DFIR) is a rapidly growing field that demands dynamic thinking and a novel approach. Combining digital investigative services with incident response expertise is critical to manage the growing complexity of modern cybersecurity incidents.

DFIR provides a deep understanding of cybersecurity incidents through a comprehensive forensic process. DFIR experts gather and investigate vast amounts of data to fill in gaps of information about cyber attacks, such as who were the attackers, how they broke in, and the exact steps they took to place systems at risk.

Today’s evolving business landscape is characterised by increasing digitisation, a move to cloud computing and relentless cyber threats penetrating even the most cutting-edge systems. Considering the volatility of the market, environmental issues, human errors and the massive volume of information, businesses can’t escape from the risks that are waiting to attack and exploit their vulnerable areas.

Digital Forensics and Incident Response (DFIR) is a field within cybersecurity that focuses on the identification, investigation, and remediation of cyberattacks.This persisting issue has raised the demand for robust digital forensics and incident response strategies for organisations, no matter their size and capacity. 

Digital Forensic and Incident Response (DFIR)

Digital Forensics and Incident Response (DFIR) is a multidisciplinary approach that combines the dynamics of uncovering the truth behind a cyber attack and responding to the attack in an efficient and swift manner.DFIR is a specialized field focused on identifying, remediating, and investigating cybersecurity incidents. As the name suggests, DFIR consists of two components: Digital forensics involves collecting, preserving, and analyzing forensic evidence.More comprehensively, DFIR covers:

Digital Forensics

  • Evidence collection from different sources
  • Data preservation to prevent its tempering
  • Evidence analysis to uncover the cause of the attack and the extent of the attack
  • Ensuring legal admissibility of the evidence

Incident response

  • Preparing an incident response plan
  • Detecting and confirming the security incident 
  • Isolating affected networks or systems to prevent the incident from spreading
  • Identifying the root cause and finding ways to eliminate its recurrence
  • Restoring the affected network and systems
  • Analysing the incident report and finding potential vulnerable areas as well as areas of improvement

As digital forensics and incident response go hand in hand, together they make businesses aware and prevent them from a host of challenges including cyber threat proliferation, data sensitivity, reputational management, business continuity and legal compliance complexities. 

The Importance of Digital Forensics and Incident Response

As the remote-based and hybrid work culture is accelerating, a robust DFIR strategy is vital for organisations to ensure their security posture, effectively investigate incidents, find security vulnerabilities, allow the least possible operational disruption, recover from cyber threats quickly, and keep the attack isolated to a small radius. 

The amalgamation of Digital Forensics with Incident Response aids the security posture through:

  • Speed and Efficacy
  • Efficient & Tailored Approach
  • Commercial & OSINT Tools/Technology
  • Standard-based Methodology/Approach
  • Post Breach Monitoring with Alerts/Notifications

Organisations that heavily rely on digital systems for data creation and processing are encountering an escalating number of sophisticated threats like advanced persistent threats (APT), ransomware assaults, and online identity risks.

In this context, today’s enterprises are compelled to equip themselves with advanced digital forensics and incident response capabilities spanning both on-premise and cloud environments. These capabilities enable rapid detection, meticulous analysis, and prompt responses to incidents, ensuring comprehensive safeguarding measures are in place.

Digital Forensic and Incident Response (DFIR)

Netrika’s Digital Forensics and Incident Response Services provide a comprehensive set of capabilities that identify gaps in the existing security infrastructure and help businesses predict, detect, and mitigate security incidents.  

DFIR is a digital emergency response field that identifies, investigates, and remediates cyberattacks and cybercrime. This field of forensics examines system data, user activity, and other digital footprints to gather evidence and nail down the process of any adverse incident(s) (attack/ breach/ fraud/ crime). 

DFIR encompasses two primary facets:

Digital Forensics: As a subset of forensic investigation, it scrutinises system data, user actions, and digital artefacts to ascertain ongoing attack instances and the identities behind such acts.

Incident Response: This comprehensive approach outlines an organisation’s strategy for pre-emptively readying, promptly detecting, efficiently containing, and methodically recuperating from potential data breaches.

 Using state-of-the-art tools, our DF experts help businesses respond to digital frauds, malware infection, hacker attacks, data theft, or any unwanted digital activities. Our DF professionals examine data on digital assets across computers, mobile phones, enterprise networks, cloud deployments, surface web, dark and deep web. They can dig deep while investigating the incident’s root cause.
