Which of the following is MOST appropriate for inclusion in an information security strategy?
Click on the arrows to vote for the correct answer
A. B. C. D.B.
A set of security objectives, processes, methods, tools and techniques together constitute a security strategy.
Although IT and business governance are intertwined, business controls may not be included in a security strategy.
Budgets will generally not be included in an information security strategy.
Additionally, until information security strategy is formulated and implemented, specific tools will not be identified and specific cost estimates will not be available.
Firewall rule sets, network defaults and intrusion detection system (IDS) settings are technical details subject to periodic change, and are not appropriate content for a strategy document.
An information security strategy is a comprehensive plan that outlines an organization's approach to protecting its sensitive information and assets from unauthorized access, use, disclosure, modification, destruction, or disruption. The strategy must be aligned with the organization's business objectives and risk tolerance and consider factors such as the nature of its operations, legal and regulatory requirements, stakeholder expectations, and emerging threats and vulnerabilities.
Out of the given options, the MOST appropriate one for inclusion in an information security strategy is "B. Security processes, methods, tools and techniques." Here's why:
A. Business controls designated as key controls: While business controls are important for achieving operational efficiency, compliance, and risk management, they may not necessarily address specific information security risks and threats. For example, a control that requires employees to use strong passwords may not prevent a hacker from exploiting a vulnerability in a web application. Therefore, including only business controls in an information security strategy may not provide adequate protection.
B. Security processes, methods, tools and techniques: Security processes, methods, tools, and techniques are fundamental components of an information security strategy as they enable the organization to implement a systematic, consistent, and measurable approach to identifying, assessing, mitigating, and monitoring security risks. These elements may include but are not limited to: access controls, encryption, authentication, monitoring and logging, incident response, vulnerability management, and security awareness and training. The inclusion of security processes, methods, tools, and techniques ensures that the organization has the means to protect its information assets against a wide range of threats and vulnerabilities.
C. Firewall rule sets, network defaults, and intrusion detection system (IDS) settings: Firewall rule sets, network defaults, and IDS settings are specific technical controls that may be part of the security processes, methods, tools, and techniques. While they are important for securing the organization's network and systems, they may not be sufficient on their own to protect all types of information assets, especially those that are not on the network or those that are accessed through cloud services, mobile devices, or third-party systems. Therefore, including only these controls in an information security strategy may not provide a comprehensive view of the organization's security posture.
D. Budget estimates to acquire specific security tools: While budget estimates are important for planning and prioritizing security investments, they are not a substitute for a comprehensive information security strategy. Without a clear understanding of the organization's security risks, threats, and vulnerabilities, budget estimates may lead to over- or under-investment in specific security tools that may not address the most critical security issues. Therefore, including only budget estimates in an information security strategy may not provide the necessary guidance for selecting and deploying security controls that are appropriate for the organization's specific security needs.
In conclusion, the MOST appropriate element to include in an information security strategy is security processes, methods, tools, and techniques as they enable the organization to implement a holistic and effective approach to protecting its information assets against a wide range of threats and vulnerabilities.
