Study Notes

Security Concepts and Goals

Security encompasses people, processes, and technology to effectively protect information assets.
Cybersecurity aims to create environments resilient against threats and attacks.

Subjects and Objects of Security

Subjects: Entities accessing information (e.g., employees, systems).
Objects: Information or systems being protected.

Security Tactics for People

Employees are critical to cybersecurity; informed staff can act as a defense line.
Cybercriminals often target employees via phishing attacks to exploit their lack of security knowledge.
Regular training is essential to raise awareness and develop a culture of cybersecurity.
Key training points include:
- Creating strong, unique passwords for each account.
- Keeping personal and work passwords separate.
- Avoiding links in suspicious emails.
- Regularly updating applications and operating systems.
- Refraining from installing unknown software.
- Reporting unusual system behavior promptly.

Security Tactics for Processes

Cyber-incident response plans are vital for proactive cybersecurity management.
Effective incident response ensures swift recovery and minimal business disruption.
Regularly testing data backups enhances data recovery chances during cyber incidents.
Continuous threat research informs security strategies and tools to mitigate risks.
Prioritizing assets is essential due to the cybersecurity skills gap and complex networks.
Implementing network segmentation and access control policies enhances data security.

Security Tactics for Technology

Integrating security technologies creates a cohesive defense strategy rather than isolated point solutions.
Deception technology leverages network complexity to mislead adversaries.
Confidentiality ensures sensitive information remains protected from unauthorized access.
Auditing security activities provides logs of both successful and unsuccessful access attempts.

IT Security Frameworks

NIST Cybersecurity Framework:
- Comprises a set of activities and desired outcomes.
- Features implementation tiers and profiles for improving cybersecurity.
ISO/IEC 27000 Series:
- A systematic approach to managing sensitive information through an Information Security Management System (ISMS).
- Involves defining security policies, conducting risk assessments, and managing identified risks.
Payment Card Industry Data Security Standard (PCI DSS):
- Aims to secure card payment processes and reduce fraud.
- Principles include securing networks, protecting card data, and implementing strong access control.

Security Architecture

Defined as a comprehensive security design addressing potential risks and outlining security controls.
Key attributes include:
- Relationships and dependencies among IT architecture components.
- Cost-effectiveness due to standardized security controls.
- Variations in form, including control catalogs and relationship diagrams.
Key Phases in Security Architecture Process:
- Architecture Risk Assessment: Evaluates risks associated with vital business assets.
- Security Architecture and Design: Focuses on implementing security services aligned with business risk exposure.
- Implementation: Involves operationalizing security services and processes.
- Operations and Monitoring: Encompasses daily security operations, including threat management and ongoing monitoring.
