Incident Response
Investigate. Contain. Recover.
When a cyber incident occurs, the first priority is to understand what happened and stop the threat from spreading.
Resecurity helps organizations investigate security incidents, determine the scope of compromise, contain malicious activity, and support secure recovery.
Digital forensics, threat hunting, malware analysis, and cyber threat intelligence are used as needed to reconstruct attacker activity across endpoints, networks, identities, cloud environments, and applications.
The first alert rarely tells the whole story.
An attacker may have accessed additional systems, used legitimate accounts, established persistence, or reached sensitive information before the incident was detected.
Resecurity helps determine how access was obtained, where the attacker moved, what systems and accounts were affected, and whether unauthorized access remains.
The response is adapted to the incident, with investigation, containment, remediation, and recovery activities prioritized around the organization's operational needs.
A clear investigation should answer the questions that matter most during a security incident.
Identify the initial access point, whether through compromised credentials, an exploited vulnerability, a malicious file, an exposed service, third-party access, or another entry vector.
Identify tools, commands, malware, infrastructure, accounts, and techniques used during the intrusion.
Determine which endpoints, servers, accounts, applications, cloud resources, and network segments were accessed or compromised.
Review evidence of unauthorized access, collection, staging, transfer, or exfiltration of sensitive information.
Build a timeline from initial access through persistence, privilege escalation, lateral movement, data access, and other observed activity.
Search for persistence mechanisms, compromised credentials, malicious services, scheduled tasks, unauthorized applications, backdoors, and other ways an attacker could maintain or regain access.
Triage & Scoping
Assess the incident, identify potentially affected systems and identities, establish priorities, and determine the immediate steps needed to limit further exposure.
Evidence Collection & Digital Forensics
Collect and preserve relevant evidence from endpoints, servers, network infrastructure, cloud environments, identities, applications, logs, and available security telemetry.
Use forensic evidence to reconstruct attacker activity and establish the timeline, scope, and impact of the compromise.
Threat Hunting & Investigation
Look beyond the systems that first triggered the investigation.
Search for indicators of compromise, suspicious processes, credential abuse, lateral movement, persistence, command-and-control activity, malicious infrastructure, and other signs of attacker activity.
Containment
Limit the attacker's ability to continue operating while preserving evidence needed for the investigation.
This may include isolating affected systems, restricting compromised accounts, blocking malicious infrastructure, disabling unauthorized access, and limiting further movement through the environment.
Eradication & Remediation
Remove identified malicious artifacts and persistence mechanisms, address compromised accounts and credentials, close discovered attack paths, and support remediation of weaknesses used during the incident.
Recovery & Validation
Support the controlled restoration of affected systems and services.
Validate that identified attacker access and persistence have been addressed before returning systems to normal operation.
Post-Incident Analysis
Document what happened, how the incident developed, what was affected, and what actions were taken.
Provide recommendations based on the investigation to improve security controls, monitoring, detection, and future response.
Resecurity supports investigations involving a range of security incidents.
Ransomware & Cyber Extortion
Investigate initial access, persistence, privilege escalation, lateral movement, encryption activity, and possible data theft while supporting containment and recovery.
Insider Activity
Examine suspected misuse of privileges, unauthorized access, intellectual property theft, data exfiltration, sabotage, and other potentially malicious internal activity.
Network Intrusions & Data Breaches
Determine how unauthorized access occurred, what systems and information were affected, and how far the intrusion spread.
Malware & Endpoint Compromise
Analyze malicious software and affected systems to understand execution, persistence, communications, capabilities, and impact.
Business Email Compromise
Investigate compromised accounts, credential theft, unauthorized mailbox access, malicious inbox rules, fraudulent communications, and related infrastructure.
Cloud & Identity Compromise
Investigate account takeover, suspicious authentication, credential or token abuse, privilege escalation, and unauthorized activity across cloud and SaaS environments.
Sophisticated Intrusions
Investigate complex or long-running activity involving credential abuse, persistence, compromised infrastructure, malware, and repeated access to targeted systems.
Supply Chain & Third-Party Compromise
Investigate incidents involving vendors, service providers, software dependencies, trusted relationships, or other third parties.
See More Than the Compromised System
Forensic evidence shows what happened inside the affected environment. Threat intelligence can provide context about what exists outside it.
Resecurity can correlate investigative findings with cyber threat intelligence to examine malicious IP addresses and domains, attacker infrastructure, compromised credentials, malware, underground activity, and related adversary behavior.
This can help identify additional infrastructure, uncover further exposure, connect activity across different parts of the investigation, and provide new indicators for threat hunting and containment.
The goal is simple: use both internal evidence and external intelligence to build a clearer picture of the incident.
Be Ready Before You Need It
During a serious incident, time should not be spent establishing basic response procedures or identifying who needs to be involved.
An Incident Response Retainer establishes the relationship in advance and creates a defined path for engaging Resecurity when support is needed.
Preparation can include identifying key contacts, critical systems, available evidence sources, escalation procedures, and technical dependencies before an incident occurs.
Pre-Incident Onboarding
Establish response contacts, escalation paths, communication procedures, critical assets, and relevant security technologies.
Incident Response Planning & Readiness
Review existing response procedures, evidence availability, logging, investigative requirements, and operational dependencies that may affect an investigation.
Tabletop Exercises
Use realistic incident scenarios to test escalation, communication, technical response, decision-making, and coordination across the organization.
Incident Response Activation
Engage Resecurity for triage, investigation, digital forensics, threat hunting, containment, remediation, and recovery support when an incident occurs.
Post-Incident Review
Review investigation findings and response actions and identify practical ways to improve future readiness.
Investigative Capabilities
Use digital forensics, threat hunting, malware analysis, and cyber threat intelligence based on the nature and scope of the incident.
Intelligence-Led Investigation
Add external threat intelligence to internal forensic evidence to provide more context around malicious infrastructure, compromised information, and related threat activity.
Visibility Across the Environment
Investigate activity across endpoints, networks, identities, cloud environments, applications, and available security telemetry.
Support for Complex Incidents
Support investigations involving ransomware, cyber extortion, sophisticated intrusions, compromised identities, insider activity, malware, data theft, and third-party compromise.
Evidence-Based Findings
Turn technical evidence into clear investigative findings, response priorities, remediation actions, and recommendations.
Coordinated Response
Work with internal security, IT, management, legal, and other authorized stakeholders throughout the investigation and response process.
A security incident creates uncertainty. The response should reduce it.
Resecurity helps organizations understand what happened, determine what remains at risk, contain malicious activity, and recover with a clearer picture of the compromise.
