Study Notes

Recap of Last Class

Cybersecurity focuses on confidentiality, integrity, and availability of IT resources.
Security threats include malware, DDOS, and social engineering; they can harm organization reputation and financial stability.
Insider threats are often underestimated.

Security Lifecycle

Security is a management issue; it involves risk assessment and mitigation.
Preventive Controls: Includes culture, training, authentication, authorization, IT solutions (e.g., firewalls, encryption), and environmental security.
Detective Controls: Encompasses log analysis and intrusion detection systems.
Response: Managed by Computer Incident Response Teams (CIRT).

Preventive Controls Overview

People: Establishing a culture of security starts with management support and funding.
Single Sign-On: Streamlines login processes, enhancing user experience but presents a single point of failure.
Employee Training: Promotes good password hygiene but risks being overlooked if excessive.
Complexity Requirements: Ensures password strength but may encourage minimal compliance.

Password Management

Regular password expiry reduces risks but can lead to predictable password patterns and increased reliance on notes.

Authorization Principles

Authorization specifies access levels to information resources, adhering to the principle of least privilege to minimize risk.
Monitoring encryption standards is crucial following incidents, such as the TJX breach which resulted in 94 million stolen credit cards.

Virtual Private Networks (VPN)

VPNs encrypt data between networks, offering secure connections without high infrastructure costs.
They require user authentication and maintain data integrity through hashing.

Detective Controls

Log analysis helps identify potential cyber threats by examining system logs.
Intrusion Detection Systems monitor approved network traffic for signs of breaches.

Incident Response Framework

Recognition: Unusual activity detection through proactive and reactive methods.
Containment: Stops incidents and mitigates damages through sorting and immediate response actions.
Recovery: Involves eradicating threats, applying patches, and restoring data from backups.
Follow-up: Analysis post-incident to assess response effectiveness and necessary policy changes.

Measuring Incident Response Effectiveness

Metrics include the number of reported/detected incidents and average response times, aiding management in understanding incident management capabilities.

Additional Resources

Websites such as krebsonsecurity.com and infosecurity-magazine.com provide further information on cybersecurity.
Consider enrolling in related courses such as AFM 347 for deeper knowledge.

Sample Quiz Questions

Authorization defined as restricting user access.
Understanding of VPN costs and functionality compared to traditional networks is essential for comprehension of secure communication channels.

Class Take-Aways

Security controls are crucial for incident prevention and response; stakeholder input is essential in design and implementation efforts.
