Evidence Collection Policy Scenario After Recent Security

Evidence Collection Policyscenarioafter The Recent Security Breach Al

Evidence Collection Policy Scenario After the recent security breach, Always Fresh decided to form a computer security incident response team (CSIRT). As a security administrator, you have been assigned the responsibility of developing a CSIRT policy that addresses incident evidence collection and handling. The goal is to ensure all evidence collected during investigations is valid and admissible in court. Consider the following questions for collecting and handling evidence: 1. What are the main concerns when collecting evidence? 2. What precautions are necessary to preserve evidence state? 3. How do you ensure evidence remains in its initial state? 4. What information and procedures are necessary to ensure evidence is admissible in court? Tasks Create a policy that ensures all evidence is collected and handled in a secure and efficient manner. Remember, you are writing a policy, not procedures. Focus on the high-level tasks, not the individual steps. Address the following in your policy: § Description of information required for items of evidence § Documentation required in addition to item details (personnel, description of circumstances, and so on) § Description of measures required to preserve initial evidence integrity § Description of measures required to preserve ongoing evidence integrity § Controls necessary to maintain evidence integrity in storage § Documentation required to demonstrate evidence integrity

Paper For Above instruction

The integrity and admissibility of digital evidence are paramount in cybersecurity investigations, especially following a significant security breach such as the recent incident at Always Fresh. Developing a comprehensive CSIRT (Computer Security Incident Response Team) policy for evidence collection and handling ensures that evidence remains valid for legal proceedings and effective for addressing security vulnerabilities. This policy must focus on high-level principles and safeguarding measures rather than procedural minutiae, emphasizing the importance of maintaining evidence integrity throughout its lifecycle.

Firstly, the policy must specify the necessary information for each item of evidence. This includes detailed descriptions that encapsulate the nature of the evidence—whether digital files, system logs, or physical devices—and unique identifiers such as serial or tracking numbers. Proper documentation should also encompass the context of collection, including the date, time, location, and circumstances, as well as personnel involved in the collection process. Such comprehensive documentation facilitates chain-of-custody and supports the evidential credibility required in court.

To preserve the original state of evidence, the policy stipulates strict precautions. For digital evidence, this involves creating forensically sound copies through write-blockers and hashing algorithms—such as MD5 or SHA-256—to authenticate copies’ integrity. Physical evidence should be carefully handled to prevent contamination or deterioration; this includes using suitable containers and environmental controls. For ongoing evidence preservation, measures include continuous monitoring of storage environments and periodic integrity checks through hash verification to detect any tampering or degradation.

Maintaining evidence integrity during storage involves implementing robust controls such as secure, access-restricted storage facilities, encrypted storage media, and detailed access logs. These controls prevent unauthorized access and ensure accountability. Documentation should include records of all access events, transfer logs, and periodic integrity validations to demonstrate compliance with evidentiary standards.

Finally, this policy emphasizes the importance of comprehensive documentation to demonstrate the authenticity and integrity of evidence in court. All actions taken—such as collection, transfer, storage, and integrity checks—must be logged meticulously. Proper record-keeping ensures the evidence’s chain-of-custody is unbroken, thereby affirming its admissibility and reliability in legal proceedings.
