    Study Notes

    Cyber Security Overview

    • Network Topology: Structure of network connections, can impact performance and security.
    • Types of Malware:
      • Virus: Infects files and spreads via attachments.
      • Worm: Self-replicating malware that spreads over networks without a host program.
      • Backdoor: Provides unauthorized remote access to systems.
      • Spyware: Monitors user activities and collects information.
      • Trojan Horse: Disguised as legitimate software, can damage systems once executed.
      • Adware: Displays unwanted advertisements, often bundled with free software.
      • Popup: Interrupts user experience by creating pop-up windows, can be related to adware.
    • Operating Systems: Base software managing computer hardware and software resources.

    Cyber Security Investigation Tools

    • Whois: Provides registration details of a domain to identify the owner.
    • Nslookup: Resolves domain names to IP addresses, useful for mapping networks.
    • Tracert: Traces the path data takes to reach a specific server, highlighting potential network issues.
    • Netstat: Displays active connections, offering insights into current network traffic and potential issues.

    Malware and Cyber Attacks

    • "ILOVEYOU" Worm: A type of malware that spread via email, it exploited human curiosity, causing massive data loss and system damage.
    • DDoS Attack: Distributes denial-of-service attacks across multiple systems to overwhelm a target, rendering it unavailable.

    Hacker Motivations

    • White Hat Hackers: Ethical hacking to improve security; aim to find and fix vulnerabilities.
    • Black Hat Hackers: Malicious intent; exploit vulnerabilities for personal gain.

    Enhancing Security Against Malware

    • Increased Risk Factors:
      • Opening unsolicited email attachments.
      • Downloading software from untrustworthy sources.
      • Ignoring software updates.
      • Lack of robust antivirus protection.

    Additional Cyber Security Concepts

    • Directory Locations for Servers:
      • Default IIS files often stored in C:\inetpub\wwwroot.
      • Logs found in subfolders for monitoring server activity.
    • Forceful Browsing: Attempts to access directories that are not directly linked, enabling potential unauthorized access.
    • Firewall Types:
      • Network Firewalls: Protect entire networks.
      • Host Level Firewalls: Protect individual devices.

    Digital Forensics Fundamentals

    • Handling Digital Evidence: Follow a strict process for documenting and preserving evidence in digital forensic investigations.
    • Live Response: Technique for collecting evidence from a powered-on device, often necessary during active incidents.

    Cryptography Basics

    • Encryption Types:
      • Symmetric Key Encryption: Same key for encryption and decryption.
      • Asymmetric Encryption: Uses a pair of keys (public and private) for secure communications.
    • Digital Data:
      • Data at Rest: Stored data (e.g., files on disk).
      • Data in Transit: Data being transferred (e.g., emails).

    Important Commands & Protocols

    • Commands:
      • whoami: Displays the current user account.
      • ipconfig: Shows the network configuration of the device.
    • Protocols: Each layer of the OSI model corresponds to various protocols defining how data is transferred over networks.

    Security Protocol Implementation

    • FTP Security: Should limit anonymous access and only be permitted under specific scenarios to prevent unauthorized file transfers.
    • Log File Management: Important for tracking access and identifying potential security breaches; should be securely stored and monitored.

    Penetration Testing Tools

    • Nessus and Metasploit: Commonly used tools by penetration testers for vulnerability scanning and exploitation respectively.
    • ZenMap Scanner: Provides a visual map of the network and identifies potential weaknesses.

    This outline provides a comprehensive view of foundational cybersecurity concepts, investigation tools, types of attacks, hacker motivations, encryption methods, and essential commands useful in cybersecurity practices.
