CSX Cybersecurity Fundamentals Three common controls used to protect the availability of information are - - Redundancy - Backups - access controls Governance has several goals, including - Providing strategic direction, Ensuring that objectives are achieved, Verifying that organization al resources are being used appropriately, Ascertaining whether risk is being managed properly. According to the NIST framework, which of the following are considered key functions necessary for the protection of digital assets? - - Protect, - Recover - Identify The best definition for cybersecurity? - Protecting information assets by addressing threats to information that is processed, stored or transported by interworked information systems Cybersecurity role that is charged with the duty of managing incidents and remediation? - Cybersecurity management The core duty of cybersecurity is to identify, respond and manage - risk to an organization's digital assets. A threat - is anything capabl e of acting against an asset in a manner that can cause harm. A asset - is something of value worth protecting. A vulnerability - is a weakness in the design, implementation, operation or internal controls in a process that could be exploited to violate the system security The path or route used to gain access to the target asset is known as a - attack vector In an attack, the container that delivers the exploit to the target is called - payload Policies - communicate required and prohibited activities and behaviors.

System hardening should implement the principle of - Least privilege or access control Which of the following ar e considered functional areas of network management as defined by ISO? - Accounting management, Fault management, Performance management, Security management Virtualization involves - Multiple guests coexisting on the same server in isolation of one anoth er Vulnerability management begins with an understanding of cybersecurity assets and their locations, which can be accomplished by - Maintaining an asset inventory. Arrange the steps of the incident response process into the correct order - Preparation, Detection and analysis, Investigation, Mitigation and recovery, Postincident analysis Which element of an incident response plan involves obtaining and preserving evidence - ContainmentThe benefits of buying summaries with Stuvia:
