Study Notes

Increasing Cybersecurity Risks and the Importance of Vulnerability Evaluation

  • Hackers and virus attacks are on the rise due to the expansion of the Internet and the availability of easy-to-use hacker tools.
  • Approximately 95% of web attack events occur because of the failure to address known security vulnerabilities in computer network systems.
  • The main cause of these vulnerabilities is the compromised computer network systems.
  • Evaluating vulnerabilities is crucial in order to effectively combat network security risks.
  • Accessible solutions are needed for customers to enhance their information security architecture through security assessments.
  • The goal is to help customers strengthen security while maintaining a high level of performance.
  • Criteria for evaluating security include SSE-CMM (Systems Security Engineering Capability Maturity Model).
  • Another criterion is ISO 17799 (BS7799), which is an information security code of practice.
  • ISO 7498-2 is a security architecture standard for information processing systems in open systems interconnection.
  • ISO 13335 is an information technology standard for managing IT security.
  • These standards and criteria serve as guidelines for organizations to improve their cybersecurity measures.
  • Implementing these standards can help mitigate the risks of cyber attacks and protect sensitive information.
