A mature information security program is one that is aligned with the business strategy, objectives, and culture, and that delivers value to the organization by effectively managing the information security risks and enhancing the security posture. Optimizing the security resources means that the program uses the available human, financial, and technical resources in the most efficient and effective way, and that it continuously monitors and improves the performance and maturity of the security processes and controls.

Comprehensive and Detailed Explanation: Employee accountability is the degree to which employees are responsible for their actions and outcomes related to information security. It reflects the extent to which employees understand their roles and responsibilities, follow the policies and procedures, report incidents and breaches, and comply with legal and regulatory requirements. Embedding security responsibilities into job descriptions helps to clarify the expectations and obligations of employees, as well as the consequences of non-compliance or negligence. It also helps to align the security objectives with the business goals and strategies, and to foster a culture of security awareness and responsibility.

Transport Layer Security (TLS) is a protocol that provides encryption, authentication, and integrity for data transmitted over the Internet. TLS protects the confidentiality of data by encrypting it before sending it and decrypting it after receiving it. TLS also verifies the identity of the communicating parties by using certificates and prevents data tampering by using message authentication codes. References = CISM Review Manual, 16th Edition, Chapter 4, Section 4.3.2.11

The answer to the question is B. Spread a site across multiple ISPs. This is because spreading a site across multiple Internet service providers (ISPs) can help to reduce the impact of a distributed denial of service (DDoS) attack by increasing the bandwidth and redundancy of the site, and making it harder for the attacker to target and overwhelm a single point of failure. Spreading a site across multiple ISPs can also help to distribute the traffic load and balance the performance of the site, and to mitigate the effects of regional or network-specific outages or disruptions. Spreading a site across multiple ISPs can be done by using various techniques, such as anycast routing, content delivery networks (CDNs), or cloud-based services12.
