The information owner is the person who has the authority and responsibility for the information asset and its protection. The information security manager should contact the information owner as soon as possible after the incident has been confirmed, to inform them of the incident, its impact, and the actions taken or planned to resolve it. The information owner may also need to be involved in the decision-making process regarding the incident response and recovery. (From CISM Review Manual 15th Edition)

Enforcing technical security standards is the most effective way to ensure that a new server is appropriately secured because it ensures that the server complies with the organization’s security policies and best practices, such as encryption, authentication, patching, and hardening. Performing secure code reviews is not relevant for securing a new server, unless it is running custom applications that need to be verified for security flaws. Conducting penetration testing is not sufficient for securing a new server, because it only identifies vulnerabilities that can be exploited by attackers, but does not fix them. Initiating security scanning is not sufficient for securing a new server, because it only detects known vulnerabilities or misconfigurations, but does not enforce security standards or remediate issues.

 A security operations center (SOC) relies on the centralized logging server to collect, store, analyze and correlate security events from various sources such as firewalls, intrusion detection systems, antivirus software, etc. The centralized logging server uses the timestamps of the events to perform the analysis and correlation. If the IT system clocks are not synchronized with the centralized logging server, the SOC will face difficulties in identifying the sequence and causality of the events, which will affect its ability to detect and respond to potential security breaches. Therefore, this presents the greatest challenge to the SOC’s awareness of potential security breaches.

Operating systems that are no longer supported by the vendor may pose a security risk, but they can be mitigated by applying compensating controls such as isolation, segmentation, monitoring, etc. The patch management system that does not deploy patches in a timely manner may also increase the vulnerability exposure, but it can be remediated by prioritizing and applying the critical patches as soon as possible. An organization that has a decentralized data center that uses cloud services may face some challenges in ensuring the security and compliance of the cloud environment, but it can leverage the cloud service provider’s security capabilities and tools to enhance the SOC’s visibility and control. Therefore, these options are not the greatest challenges to the SOC’s awareness of potential security breaches. References = CISM Certified Information Security Manager Study Guide, Chapter 8: Security Operations and Incident Management, page 2691; CISM Foundations: Module 4 Course, Part One: Security Operations and Incident Management2; RSI Security, Common Challenges of SOC Teams3; Infosec Matter, Security Operations Center: Challenges of SOC Teams4
