Study Notes
Forensic Analysis for Computer Systems
- Course plan outlines five key areas: Introduction, Evolution of Computer Forensics, Computer Forensics Process, Types of Computer Forensics, and Forensics Readiness.
Forensics Readiness
-
5.1 Introduction: Modern digital technologies present both opportunities and issues requiring solutions. Rising cybercrime threats necessitate proactive measures for organizations and law enforcement to enhance response to security incidents and create a digital forensic-ready environment.
-
5.1 Introduction (cont.): Forensic readiness is the ability of an organization to maximize its potential to use digital evidence while minimizing investigation costs. It involves achieving an appropriate level of capability to collect, preserve, protect, and analyze digital evidence.
-
5.1 Introduction (cont.): The ability to use digital evidence for legal actions, employment tribunals, and disciplinary matters is critical. Forensic readiness, as defined by Mohay, assesses the extent to which computer systems and networks record activities and data, ensuring sufficient records for forensic investigations.
-
5.1 Introduction (Example Scenarios): Two scenarios illustrate different approaches to computer system security. Scenario 1 relies on basic visitor passes and CCTV, while Scenario 2 emphasizes detailed visitor tracking and logging across all floors.
-
5.2 Goals of Forensic Readiness: The goals aim to: gather admissible evidence without interfering with business, target potential crimes affecting the organization, allow investigations proportional to the incident, minimize business interruption during investigations, and ensure evidence effectively impacts legal actions.
-
5.3 Forensic Readiness Steps (1): Define business scenarios requiring digital evidence to assess risk and potential impact from various crimes and disputes, identifying vulnerable areas.
-
5.3 Forensic Readiness Steps (2): Identify available sources and types of potential evidence, considering computer logs and their origins.
-
5.3 Forensic Readiness Steps (3): Determine evidence collection requirements to communicate with those managing business risks and corporate security. Key is bringing IT and security needs together.
-
5.3 Forensic Readiness Steps (4): Establish a secure capability for gathering legally admissible evidence to meet requirements, considering budget and relevant sources, while maintaining authenticity as evidence.
-
5.3 Forensic Readiness Steps (5): Establish policies for secure storage and handling of potential evidence for long-term retrieval.
-
5.3 Forensic Readiness Steps (6): Ensure monitoring is focused on detecting and deterring major incidents, including intrusion detection systems extended beyond network attacks.
-
5.3 Forensic Readiness Steps (7): Specifying circumstances for escalation to formal investigations, noting whether suspicious events are system-generated or based on human observation, needing escalation, monitoring, or dismissal.
-
5.3 Forensic Readiness Steps (8): Training staff in incident awareness and roles in the digital evidence process, legal sensitivities, and handling incident response.
-
5.3 Forensic Readiness Steps (9): Document an evidence-based, credible case describing the incident and its impact, detailing who, what, when, where, and how to build a solid argument.
-
5.3 Forensic Readiness Steps (10): Ensure legal review for appropriate follow-up actions, considering if additional methods like monitoring and seizing internal PCs are necessary for catching internal suspects if evidence is weak.
-
5.4 Benefits of Forensic Readiness: Forensic readiness benefits include gathering evidence for lawsuits, preventing insider threats, enabling efficient major incident investigations and reducing time/costs for internal investigations, efficiently handling court-ordered disclosures, and responding to regulatory and legal data disclosure requests.
-
5.4 Benefits of Forensic Readiness (cont.): Forensics can also extend information security coverage, demonstrating due diligence and governance of information assets and enabling employee sanctions based on digital evidence (using acceptable use policies).
-
5.5 Digital Forensic Readiness Features: Discusses features like regulatory compliance from guidelines (e.g., ISO 27000 series), legal requirements (e.g., the IT Act, Civil/Criminal disputes), employee misconduct (corporate policy violations, unauthorized access), business impact analysis and monitoring, threat detection, log correlation, and insurance claims.
-
5.5 Digital Forensic Readiness Features (cont.): Includes recommendations for applications handling sensitive information, backed up critical application logs, robust monitoring systems, securing evidence retention for legal review, and evidence storage policy compliance. Digital Forensics is no longer reactive but proactive and predictive.
-
5.5 Digital Forensic Readiness Features (cont.): A checklist is provided for identifying business scenarios and threats, mapping data sources, identifying compliance, testing collection and chain of custody, documenting incident details and impact, and ensuring appropriate legal review procedures, including regular testing for sufficiency. A list of supporting ISO standards is also included.
-
5.5 Digital Forensic Readiness Features (cont): An assessment approach for digital forensic readiness is outlined, covering existing network architecture, application processes, governance, threat types (internal and external), log collection policies, and critical business applications (including firewalls, load balancers, etc.).
-
5.5 Digital Forensic Readiness Features (cont.): The approach also covers cyber incident response policies, legal and regulatory compliance, and gap analysis between existing systems and standards (such as from ISO). Additional details on logging specifics for different attack types are provided.
