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.
