Study Notes

Network Security Fundamentals

Procedures and technologies in network security must guarantee confidentiality, integrity, and availability of data.
Integrity of data ensures that information remains accurate and unaltered, protecting against unauthorized modifications.
Availability in information security refers to ensuring that systems and data are accessible to authorized users when needed.

Influence of Business and Risk Management

Business goals and risk management shape network security needs by identifying critical assets and safeguarding against potential threats.
Countermeasures are actions taken to reduce risk, addressing vulnerabilities and defending against threats.

CVSS and Vulnerability Assessment

The Common Vulnerability Scoring System (CVSS) helps security professionals prioritize responses by assessing the severity of vulnerabilities.
A vulnerability assessment aims to identify and evaluate security weaknesses in a system, helping organizations strengthen defenses.

Relationship between Risk and Security

Risk is the potential for loss or damage related to vulnerabilities and threat vectors, highlighting the need for protective measures.
Vulnerabilities are typically found in software, hardware, networks, or procedures, making them critical to assess for security.
Risk and impact are interconnected; higher risks may lead to more significant impacts if threats exploit vulnerabilities.

Access and Control in Data Security

Data security mechanisms ensure that only authorized users can modify sensitive information, maintaining data integrity.
In network security, availability guarantees that network services are operational, preventing downtime and loss of access.

Current Security Environment

The evolving landscape of cyber threats influences the need for robust network security measures, driving organizations to adapt.
Security services in a network primarily aim to protect data integrity, maintain availability, and ensure secure access.

Assets and Vulnerabilities

In network security, an asset refers to any data, device, or resource that must be protected from threats and vulnerabilities.
A vulnerability represents a flaw or weakness that could be exploited by threats, underscoring the importance of continuous assessment and improvement in security practices.
