What is Digital Forensics and Incident Response (DFIR)

Digital Forensics and Incident Response (DFIR) is prepared to mitigate incidences where we have to analyse and manage all dimensions of cybersecurity. DFIR is therefore multi-faceted, as it not only ensures active surveillance and management of potential breaches but also deals with Forensics. This entails investigating, understanding, and solving cybersecurity issues. This ensures that legal and operational resources are digitally preserved; thus, no significant details are lost. Moreover, it prevents breaches from happening again in the future.

DFIR also assists with containment of active breaches. When attacks such as ransomware, insider abuse, and advanced persistent intrusions succeed, DFIR operationalises the developed frameworks. This promptly engineers self-healing and continuously improves all systems after promptly developing frameworks. This integrates retention, detection, and responsive operational risk frameworks for integrated loss.

DFIR involves the rapid identification of breaches and additional malicious activities and the automated controls to constrain the activity in a timely fashion.

Forensics imaging and the implementation of a cyber lock chain of custodial processes to capture and protect evidence of ephemeral data and digital artefacts.

Detailed examinations of cyber constructs like system logs, volatile and non-volatile memory, and net flows in order to pinpoint the geographic origination of the breach and the adversarial system.

Reverse engineering to determine the precise remediation procedures of the infected pathways created by the malicious code.

Restoration of infected cyber constructs, eradication of malicious elements, and the enhancement of compromised security control mechanisms.

Forensic and comprehensive documentation and reporting of created forensics detailed to meet the regulatory compliance frameworks of ISO 27001, SOC 2, PCI DSS and GDPR.

Why Organizations Need Digital Forensics and Incident Response (DFIR) Services

Respond Rapidly to Cyber Incidents and Minimize Impact

In the scope of a cyber incident, every moment counts. Failure to contain an attack can result in irreversible data loss, a prolonged suspension of operations, and lasting damage to the organisation's reputation. The complexity of modern cyberattacks often exceeds the scope of recovery processes and protocols in place within IT services. With the immediate-response DFIR Services from PlutoSec, cyber response services deploy breach containment and damage mitigation within the scope of legal evidence preservation. PlutoSec experts prioritise business continuity while isolating and neutralising threats and compromised systems for forensic analyses.

Identify Root Causes and Prevent Recurrence

Most organisations in cyber breach recoveries fail to establish a baseline understanding of how the breach occurred. This oversight in discovery leaves the organisation exposed to further exploitation. Attackers employ the same tactics, techniques, and procedures (TTPs) with little operational detection and response (D&R) to remain unresolved. PlutoSec follows a unique and proven methodology for cyber forensic investigations to establish and document attack-line integrity and evade routes, accurately depicting an attacker's technical model and operational processes (TTPs). This analysis enables organisations to strengthen and expand perimeter defences and counteractive foothold controls, sabotage attack line integrity, and radically improve the cyber breach landscape for the organisation.

Preserve Evidence for Legal and Regulatory Needs

Failure to observe standards and procedures for the collection of evidence adversely impacts investigations, augments an absence of evidence and legal cases, and significantly reduces the scope of the organisation's cyber insurance coverage. Special responsive services based on the collection, preservation, and analysis of evidence. PlutoSec obtains and preserves forensic integrity through reliable sustainment acquisition procedures, secure imaging, and unbroken chain-of-custody protocols. Our analysts uphold the evidentiary standards of law enforcement and regulatory agencies, as well as provide defensible documentation for litigation, insurance, and compliance-related investigations.

Contain Ransomware and Advanced Threats Effectively

Ransomware attacks and Advanced Persistent Threats (APTs) can completely immobilise a network within a couple of minutes. Most organisations do not have the right software tools and human resources to efficiently contain these threats. The DFIR team at PlutoSec uses automated isolation, forensic triage, and decryption analysis. We stop the attacks in progress and analyse the scope of encrypted or stolen data while creating a custom data recovery plan that allows the organisation to restore operations without giving the attacker a greater advantage.

Strengthen Compliance and Audit Readiness

Since the regulatory environment has changed, organisations must demonstrate effective reporting and evidence retention as well as automated incident response during a given time window. Manual recovery cannot meet these requirements, and regulatory compliance cannot be adequately addressed. PlutoSec incorporates forensic documentation and incident reporting seamlessly within DFIR workflows. Our documentation addresses transparency and compliance with standards such as ISO 27001, SOC 2, GDPR and PCI-DSS while also ensuring accountability at every stage of the incident and providing the organisation the opportunity to develop mechanisms to protect these compliance standards from documentation-based threats.

Augment SOC Capabilities and Threat Intelligence

All SOCs, even the most sophisticated, encounter obstacles during and after an incident, and those associated with intelligence provide context needed to drive mitigation and maintain control of the situation with minimal interruption. PlutoSec provides SOC operations with an additional layer of forensic intelligence across a full spectrum of operations, creating additional contextual data needed to enrich SIEM and SOAR systems and providing the incident response team greater capacity to move from reactive containment strategies to a continuous improvement model.

How We Ensure the Best DFIR Experience

At PlutoSec, Digital Forensics and Incident Response (DFIR) activities incorporate investigation, automation, and human expertise, enabling tailored, structured, automated, and human expertise responses to cyber incidents. Each engagement aims to contain active threats, safeguard digital evidence, and resume business activities as quickly as possible while balancing forensic fidelity and operational risks.

Using a custom, multi-step approach uniting rhythmic data forensic analysis, threat intelligence, and root cause analysis, we respond to ransomware, insider threats, and supply chain intrusions while retaining order in the chaos. PlutoSec helps enterprises navigate the immediate operational and security challenges of retaliation and defensive containment and operational risks. Our DFIR Process Framework

During the security incident, we start with containment of the compromised systems, interruption of any ongoing attacks, and preservation of ongoing active data. Our triage procedure ensures we neutralise active threats before forensic incidents escalate, allowing a safe and effective operational forensic analysis.

Using evidence recording and custody, verified forensic imaging, and retention of multiple forensic standards, PlutoSec retains vital data from endpoints, networks, and cloud assets.

Operational logs, memory dump files, and artefacts are carefully examined in order to disclose the accessible evidence, the entries, aims, hypotheses, and possible actions. The team reconstructs complete incident timelines and hypotheses in order to present a comprehensive circumstantial overview of the systems.

PlutoSec conducts malicious reverse engineering analysis and analyses malware samples to pinpoint key features that are indicators of compromise (IOCs), established persistence mechanisms, and pulled data from devices. This work helps shape the strategic containment and inform future preventative approaches.

After collecting data on the scope of the malware and the systems it impacted, PlutoSec removes malware, returns systems to operational status, and adjusts to new system configurations. Continuing on the collateral, our team implements security patches, conducts reviews of access permissions, and strengthens system security monitoring to mitigate any further risk.

We provide all clients impacted with value-added post-engagement forensic deliverables with fully wrapped reports which detail step-by-step the timeline of identified issues, evidence found, trace remediation actions taken, and deliverables completed. Each engagement concludes with, post-incident review, compliance review, with recommendations to elevate and improve your security posture.

Our personnel isolate the affected devices, remove the threats, and apply forensic controls to stop the incident from spreading using automated crisis management. With our continuous overseeing and managing in real-time, we make sure to stabilise in a timely manner the environments that have been compromised and sustain the evidence without losing downtime or losing operational governance in all the affected systems.

Forensic Data Collection and Evidence Preservation

PlutoSec's forensic specialists gather digital evidence from servers, endpoints, and the cloud using cutting-edge acquisition methods. We make sure that evidence is preserved for future legal or compliance purposes. All evidence is kept in a locked environment and is accessible to those with appropriate credentials, allowing us to provide evidence of due diligence for compliance, digital asset investigations, security incidents, or litigation.

Root Cause and Attack Vector Analysis

PlutoSec goes to great lengths to conduct forensic analysis and engineering to determine the methods systems are trespassed. We purposefully cross-examine fragmented event logs, network traces, and memory dumps in order to discover initial attack vectors, the compromised systems, and the techniques. This situation analysis equips organisations with points of action to eliminate caveats, establish new perimeters, and safeguard against the same intrusion from ever occurring, all while offering full transparency of the methods and motivation behind the breach.

Malware and Ransomware Investigation

Threat analysis at PlutoSec encompasses extracting and running malware samples in cyber ranges to assess their runtime behaviour, evasive strategies, and detection heuristics. This results in the development and activation of comprehensive samplers that allow clients to neutralise ransomware attacks and prevent future occurrences, as well as implement rules for the advanced detection of ransomware and malware targeted against them.

Insider Threat and Data Theft Investigation

Insider incidents, including unauthorised access, use, and unauthorised data extraction and removal, are investigated. PlutoSec uses behavioral analytics with system forensics to trace movements of files, anomalous login behaviours, and unusual logins, as well as logical empty storage and retention practices. Our findings identify compromised account access, intentional collusion of insiders, or circumvention of company policies. The data obtained are actionable to support litigation, strengthen countermeasures to insider risk, and rebuild confidence in the processes of data governance, with the assurance that the organisation will maintain privacy and confidentiality throughout the investigation.

Cloud and Hybrid Environment Forensics

PlutoSec performs digital forensics on multi-cloud and hybrid infrastructures, collecting evidence for AWS, Azure, GCP, and on-prem environments. Using our cloud-native forensics tools, we securely capture virtual discs, network data, and access credentials.

This unclouds and simplifies existing forensic interlocks and positions us for complex investigations in multi-hybrid enterprise ecosystems.

Compromise Assessment and Threat Hunting

PlutoSec has the ability to find hidden and undetected threats, as well as persistence on the host and enterprise systems. This is done by the analysts, who conduct network forensics, memory capture and analysis, and deploy various threat intel mechanisms to identify malicious dormant compromises. This compromise assessment helps detect and validate threats early, helping organisations improve their security posture and overall systems and data integrity.

Post-Incident Recovery and Remediation

Post-containment, PlutoSec works on the restoration of the affected systems and the removal of malicious actors, all while preserving evidence. We closely adapt and build systems with security in mind, maintain system integrity, and apply patches on the security holes opened during the incident. Our extended guidance remediation allows organisations to recover operationally while remaining resilient and minimising downtime in enterprise network systems.

Legal, Regulatory, and Compliance Reporting

PlutoSec prepares forensic reports according to ISO 27001, SOC 2, GDPR, and PCI-DSS standards and maintains these reports to include timeframes, impact assessments, and actions taken to remediate them for legal, insurance, and auditing purposes. We prepare each report according to forensic standards to ensure transparency and accountability and to prepare documentation for possible external audits or legal actions due to grave security incidents or data breaches.

Digital Forensics Readiness and Training

PlutoSec assists in filing for Digital Forensics Proactive Readiness for organisations by creating internal playbooks, data retention policies, and evidence collection procedures. We train SOC and IT teams to prepare for and enhance investigative skills to ensure that all participants in the response has the ability to efficiently act, evidence is properly secured, and all actions taken are compliant, regardless of the cybersecurity outcome.

Frequently Asked Questions

Get answers to common questions about our cybersecurity services and how we can protect your business.

1.What is Digital Forensics and Incident Response (DFIR)?

DFIR is a subset of cybersecurity that is disseminated into disciplines and specialises in the investigation of a particular incident (collecting and analysing evidence) and responding to a specific cyber defence. This discipline enables entities to analyse the attacking mechanisms in order to secure the system and recover the system compliantly and evidentially.

2.How does DFIR differ from standard incident response?

What truly sets this discipline apart is the forensic audit of the system response. DFIR pinpoint the behaviours of the attackers or the primary focus of the data they are wanting to access. DFIR also audits the systems with the intent of pinpointing the origins of the breach. This type of approach aids in being able to sustain containment and strengthens preventive measures to circumvent a future breach.

3.Why should enterprises invest in DFIR services?

DFIR services considerably mitigate the cyber incident downtime; the DFIR service retains the evidential components as they work through the incident, and the DFIR service also mitigates the overall incident. If a cyber incident occurs, the incident will be mitigated, with the preserving of evidential components, and the incident will be recovered rapidly. For operational resilience and overall operational protection, DFIR service’s rapid containment, forensic precision, and compliance capabilities are met.

4.How quickly can PlutoSec respond to an incident?

PlutoSec is able to respond to an incident almost immediately. The PlutoSec position is a global DFIR position which allows them to operate 24/7 with immediate responding capabilities. Once the incident has been notified, the analyst has more than enough ability to contain the incident within a few minutes to stabilise the overall business operations.

5.Can DFIR help recover from ransomware attacks?

Certainly. Analysts from PlutoSec’s DFIR study the behaviour of ransomware, quarantine affected systems, and study the patterns of system encryption. DFIR determines available recovery options, eliminates persistence mechanisms, and assists in the secure restoration of data while keeping forensic evidence intact and ensuring no additional jeopardy is created with respect to ongoing security.

6.How does PlutoSec ensure evidence integrity?

Our organisation keeps all forensic evidence practices where we maintain imaging verification and hash functions and document all chains of evidence. All evidence is maintained systematically and is preserved to ensure that evidence and all other data remain untampered with for the entire investigation.

7.Does DFIR cover cloud-based incidents?

No, it is not limited. PlutoSec performs forensics in the cloud, hybrid, and on-premises. Our cloud-based tools and services ensure archival within legal parameters and document control and compliance to capture evidence, audit logs, and access data for services deployed on public clouds (AWS, Azure, GCP).

8.Can DFIR support compliance and audit requirements?

Yes. DFIR documentation, in most of the cases, complies with the requirements of ISO 27001, SOC 2, PCI-DSS, and GDPR. Our documentation and reports act as a primary compliance audit trail, and our reports describe the evidence trail, proactive and reactive measures taken, and an incident report to assist compliance audit requirements.

9.How does DFIR enhance future threat prevention?

Every DFIR engagement ends with a root cause analysis and security recommendations. PlutoSec integrates these recommendations into the existing control frameworks to improve the SOC capabilities and defences of the organisation from the exploitation of other vulnerabilities.
