Linux Incident Response services include:

  • IR Playbooks:
    • Incident response playbooks are comprehensive guides that outline the steps and procedures an organization should follow when responding to a specific type of cybersecurity incident. These playbooks are a key component of an organization's incident response plan and serve as a structured and predefined set of actions to be taken during an incident. The goal is to ensure a consistent, organized, and effective response to various types of security incidents.
  • Incident Identification:
    • Clearly defined criteria for identifying and classifying incidents, including signs and indicators of compromise.
  • Roles and Responsibilities:
    • Assign specific roles and responsibilities to individuals or teams involved in the incident response process. This ensures that everyone knows their tasks and can act promptly.
  • Communication plans:
    • Guidelines for internal and external communication during an incident, including who to notify, what information to share, and how to communicate with stakeholders, management, and the public if necessary.
  • Incident Containment:
    • Step-by-step procedures for containing the incident to prevent further damage or unauthorized access. This may involve isolating affected systems, blocking malicious network traffic, or taking other immediate actions.
  • Eradication and Recovery:
    • Procedures for removing the root cause of the incident (eradication) and restoring affected systems to normal operation (recovery). This may involve patching vulnerabilities, removing malware, and ensuring the integrity of systems.
  • Forensics Investigations:
    • Steps for conducting a forensic investigation to determine the scope and impact of the incident. This may include memory and disk analysis, log examination, and other investigative techniques.
  • Documentation:
    • Instructions on documenting all actions taken during the incident response process. This documentation is crucial for post-incident analysis, reporting, and legal or regulatory compliance.
  • Legal and Compliance Considerations:
    • Guidance on handling legal and regulatory requirements, such as data breach notifications, reporting to authorities, and preserving evidence for potential legal proceedings.
  • Lessons learned:
    • A section for post-incident analysis and lessons learned. This involves evaluating the effectiveness of the response, identifying areas for improvement, and updating the incident response playbook accordingly.

From technical point of view our offer includes:

  • Memory Forensics:
    • Memory forensics is often a crucial component of incident response activities. It helps investigators understand the activities of a system during a security incident, such as the presence of malware, evidence of an attack, or the actions of an intruder.
    • Forensic Tools: Specialized tools are used in memory forensics to acquire and analyze the contents of RAM. These tools can extract valuable information without altering the state of the system.
    • Malware Analysis:: Memory forensics is a valuable technique in the field of malware analysis. It allows analysts to identify and understand the behavior of malicious code, even if the malware is designed to be stealthy or evasive.
    • Timeline Reconstruction: Memory forensics contributes to the reconstruction of a timeline of events during an incident. By analyzing the memory snapshots at different points in time, investigators can piece together the sequence of actions taken by an attacker or a system.
    • Detection of Artifacts: Various artifacts left in memory, such as process metadata, network connections, and remnants of executed commands, can provide insights into the activities of users and potential security threats.
  • Live Forensics:
    • Focus: Live forensics is focused on in-depth investigation and analysis after a security incident has been identified or suspected.
    • Methodology: It involves the real-time analysis of a system or network to gather evidence, understand the scope of an incident, and determine the extent of the compromise.
    • Goal: The primary goal of live forensics is to understand how an incident occurred, what data might have been compromised, and to gather evidence that can be used for legal or disciplinary actions.
    • Time Sensitivity: While live forensics is performed "live" or in real-time, it also involves preserving evidence for later analysis. It's more concerned with a thorough understanding of the incident than immediate response.
