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.
