    Study Notes

    Storage Media and Redundancy

    • Redundancy provides protection against the failure of a single storage device.
    • Redundant Array of Inexpensive Disks (RAID) offers various configurations to ensure data redundancy through additional disks.
    • Single Point of Failure (SPOF) analysis identifies and mitigates risks of system vulnerabilities.
    • Cost-benefit analysis helps determine if addressing SPOF risks is warranted.
    • SPOF analysis applies beyond IT, including management practices and vendor reliance.

    Continued Operation of Systems

    • High Availability uses multiple systems to maintain service in case of failure.
    • Internet Protocol (IP) Layer 4: The Transport Layer ensures reliable data transfer.

    IP Addressing

    • IP addresses consist of 8-bit binary numbers, allowing for 256 unique values (0 to 255).
    • Duplicates are allowed in private networks; uniqueness is required for public IPs.
    • Network Address and Host Address components define an IP address, where subnetting aids efficient routing.

    IP Address Versioning

    • IPv4 is nearing exhaustion; transition to IPv6 is underway.
    • IPv6 employs 128-bit addresses, featuring 8 groups of 4 hexadecimal numbers for vastly expanded address space.

    IP Address Assignment

    • Static IPs require manual assignment and must be unique within a network.
    • Dynamic IPs are assigned from an administrator-configured pool, allowing flexibility across devices.

    Data Protection and User Education

    • Strong, unique passwords enhance data security for organizations.
    • Users need education on protecting their own personal information.
    • Organizations must safeguard entrusted client data.

    Multi-Factor Authentication

    • Three authentication factors include something you know (passwords), something you are (biometric verification), and something you have (tokens).
    • Multi-Factor Authentication enhances security by combining different factors.
    • Passwords and security questions alone do not constitute multi-factor authentication.

    Threat Identification and Prevention

    • Intrusion Detection Systems (IDS) monitor network traffic for malicious activity and alert administrators.
    • Common threats involve SQL Injections, malformed packets, unusual logins, and botnet traffic.
    • Intrusion Prevention Systems (IPS) can actively block malicious traffic based on detection.

    IPS Deployment Modes

    • In-band deployments put IPS in the direct path of network traffic, with blocking capabilities but risk of becoming a single point of failure.
    • Out-of-band deployments allow passive monitoring outside of direct traffic flow, reducing disruption risk but requiring action from administrators for threats.

    Privacy Expectations and Regulations

    • Reasonable expectation of privacy governs how data disclosures are regulated.
    • Personally Identifiable Information (PII) and Protected Health Information (PHI) are two crucial types of private data requiring protection under laws like HIPAA.
