CISSP Crash Course - Security in Systems

The video tutorial covers various aspects of system security, including potential vulnerabilities in system components, client and server systems, and database security. It also explores industrial control systems, cloud and distributed systems, and the Internet of Things (IoT), highlighting security challenges and solutions. The tutorial emphasizes the importance of understanding different system architectures and implementing appropriate security measures to protect against attacks.

Which of the following is a potential vulnerability in client-based systems?

• Keystroke loggers

• Firmware vulnerabilities

• Mobile code execution

• Network device vulnerabilities

What is a common threat to server-based systems?

• Denial of service attacks

• Keystroke logging

• Firmware updates

• Local cache attacks

Which type of database model uses a logical tree structure?

• Relational database

• Hierarchical data model

• NoSQL database

• Graph database

What is the role of a primary key in a relational database?

• To store data in a graph format

• To uniquely identify a record

• To store information in a document format

• To enforce relationships between tables

Which component of industrial control systems allows human interaction with machines?

• PLC

• HMI

• DCS

• SCADA

In a cloud service model, who is responsible for security in a SaaS environment?

• The software developer

• The network administrator

• The cloud service provider

• The customer

What is a key advantage of cloud systems in terms of security?

• Simplified user access
