Cyber Security Basics Quiz

Cyber Security

• Definition: Protection of systems, networks, and programs from digital attacks.

• Goals:

  • Confidentiality: Ensuring that information is accessible only to those authorized.
  • Integrity: Maintaining the accuracy and completeness of data.
  • Availability: Ensuring that authorized users have access to information and associated assets when required.

• Types of Cyber Threats:

  • Malware: Malicious software such as viruses, worms, and ransomware.
  • Phishing: Fraudulent attempts to obtain sensitive information by disguising as a trustworthy entity.
  • Denial of Service (DoS): Attacks aimed at making a service unavailable to its intended users.
  • Insider Threats: Security risks coming from within the organization.

• Key Concepts:

  • Firewalls: Systems that monitor and control incoming and outgoing network traffic.
  • Encryption: The process of encoding information to prevent unauthorized access.
  • Authentication: Verifying the identity of a user or device.
  • Intrusion Detection Systems (IDS): Tools that monitor network traffic for suspicious activity.

Cyber Forensics

• Definition: The practice of collecting, analyzing, and preserving digital evidence from computers and networks.

• Objectives:

  • Identify and preserve digital evidence for legal proceedings.
  • Analyze data to determine how a cyber incident occurred.
  • Provide expert testimony in legal cases involving cyber crimes.

• Processes:

  • Identification: Recognizing potential digital evidence.
  • Preservation: Securing and maintaining the integrity of evidence.
  • Analysis: Using tools and techniques to examine the evidence.
  • Documentation: Recording findings and methodologies for reporting.

• Tools and Techniques:

  • Disk Imaging: Creating a bit-for-bit copy of storage devices for analysis.
  • Forensic Software: Tools like EnCase, FTK, and Sleuth Kit for analyzing data.
  • Chain of Custody: Maintaining a documented history of evidence handling to ensure admissibility in court.

• Legal Considerations:

  • Adherence to laws and regulations governing privacy and data protection.
  • Understanding of relevant legal standards for digital evidence.
  • Ensuring that forensic activities do not alter or damage original evidence.

Interrelationship

• Cyber security and forensic science work together to enhance the overall security posture and response to incidents.
• Effective cyber security measures can reduce the likelihood of incidents requiring forensic analysis.
• Post-incident forensic analysis provides insights that can improve future cyber security strategies.

Cyber Security

• Protection of systems, networks, and programs from digital attacks.
• Goals include:
  • Confidentiality: Restricting access to authorized individuals only.
  • Integrity: Ensuring accuracy and completeness of data.
  • Availability: Guaranteeing access for authorized users when needed.
• Types of Cyber Threats consist of:
  • Malware: Includes viruses, worms, and ransomware designed to harm systems.
  • Phishing: Attempts to trick users into revealing personal information by pretending to be a legitimate entity.
  • Denial of Service (DoS): Attacks that disrupt services, making them unavailable to users.
  • Insider Threats: Security risks posed by individuals within the organization.
• Key Concepts in cyber security:
  • Firewalls: Monitor and regulate network traffic to prevent unauthorized access.
  • Encryption: Encodes information to safeguard against unauthorized access.
  • Authentication: Confirms the identity of users or devices attempting to access resources.
  • Intrusion Detection Systems (IDS): Tools that flag suspicious network traffic for investigation.

Cyber Forensics

• Collection, analysis, and preservation of digital evidence from computers and networks.
• Objectives include:
  • Identifying and preserving evidence for legal actions.
  • Analyzing incidents to understand their causes.
  • Providing expert testimony on cyber crimes.
• Processes involved in cyber forensics:
  • Identification: Recognizing potential digital evidence.
  • Preservation: Securing and maintaining the integrity of evidence collected.
  • Analysis: Employing tools to examine found evidence comprehensively.
  • Documentation: Keeping thorough records of methodologies and findings for reporting purposes.
• Tools and Techniques:
  • Disk Imaging: Making exact copies of storage devices for forensic analysis.
  • Forensic Software: Programs like EnCase, FTK, and Sleuth Kit for data analysis.
  • Chain of Custody: Keeping a documented trail of evidence handling for court admissibility.
• Legal Considerations:
  • Compliance with privacy laws and data protection regulations.
  • Awareness of legal standards for processing digital evidence.
  • Prevention of alteration or damage to original evidence during forensic activities.

Interrelationship

• Cyber security and forensic science collaborate to improve security and incident response.
• Robust cyber security practices lower the risk of incidents needing forensic investigation.
• Forensic analysis post-incident offers insights to enhance future cyber security measures.
