Information Security and Access Quiz

Course Reference

• The course textbook is the main reference for any questions.

Social Engineering Attacks

• A common method is phishing.

Spam

• The primary purpose is to advertise.

Phishing Attacks

• The main goal is to steal sensitive information.

Buffer Overflow

• A buffer overflow can cause a system crash or allow attackers to gain unauthorized access.

Information Security Management Models

• The ISO 27000 series provides recommendations for information security management.

Critical Characteristics of Information

• Critical characteristics of information include confidentiality, integrity, availability, authenticity, and non-repudiation.

Vulnerability

• A vulnerability is a weakness in a system, which can be exploited by an attacker.

Authentication

• The purpose of authentication in information security is to verify the identity of a user or device.

CIA Triad

• The CIA triad is a model for information security that emphasizes confidentiality, integrity, and availability.

McCumber Cube

• The McCumber cube is used to analyze and visualize information security risks.

Security

• Security refers to protecting information and systems from unauthorized access, use, disclosure, disruption, modification, or destruction.

Computer, Network, OS & Information Security

• Computer, network, operating system, and information security are all interconnected and work together to protect information.

Attacks

• Based on the current landscape of security threats, it's certain that attacks will persist.

Security Attack Examples

• Examples include network attacks like denial of service (DoS) attacks, malware like viruses and trojans, and social engineering like phishing attacks.

Stuxnet

• Stuxnet was a sophisticated malware that disrupted industrial control systems, causing significant damage.

Attackers with Political/Social Causes

• Hacktivists are motivated by political and social causes.

Viruses

• Viruses, unlike worms, require human interaction to spread.

Trojan Horses

• Trojans are disguised as legitimate software and are used to steal data or grant access to the system.

Virus Spread

• Viruses typically spread through infected files, attachments, or websites.

Malware Classification

• Malware classification helps to understand the various types of malware and their effects.

Malware that Hides Log-in Records

• Rootkits are designed to hide traces of log-in records.

Malware Triggered by Events

• Logic bombs are malware that lies dormant until triggered by a specific logical event.

Backdoors

• Backdoors in software code allow unauthorized access to a system.

Spyware

• Spyware is malware that collects personal information without the user's knowledge.

IP Spoofing

• In a man-in-the-middle attack, IP spoofing allows an attacker to intercept communication between two parties.

Course Exams

• Exams require understanding of information security concepts, techniques, technologies, and practices.

Course Grading

• Grades are determined based on exam performance, class participation, and assignments, including practical exercises.

Building Knowledge in the Course

• The primary motivation is to build a foundational understanding of information security principles and practices.

Purpose of Authentication

• The purpose of authentication is to ensure the validity of a user or entity's identity.

IP Spoofing Purpose

• IP spoofing is primarily used to deceive the recipient of a communication about the source of the communication.

Malware Designed to Hide Log-in Records

• Rootkits are designed to cover up traces of malicious activities, like log-in records.

Phishing Emails

• Phishing emails appear to come from a legitimate source, but aim to trick users into revealing private information.

Spam

• Spam is unwanted and unsolicited messages sent to a large number of people.

Buffer Overflow

• Buffer overflow occurs when a program tries to write more data into a buffer than it can hold, potentially leading to data corruption or system crashes.

Keylogger

• A keylogger records all the keys that a user types on a keyboard.

Denial-of-Service (DoS) attack

• The main goal of a DoS attack is to prevent legitimate users from accessing a service.

Difference Between Viruses and Worms

• The key difference is that viruses require human interaction, while worms can spread independently.

Trojan Function

• Trojans are designed to give an attacker unauthorized access to a system.

Attackers Motivated by Political/Social Causes

• Hacktivists are groups motivated by political or social causes.

Security & Trust

• Security attempts to prevent unauthorized access, while trust assumes that there is no threat.

Information Security Definition

• Information security refers to protecting information and systems from unauthorized access, use, disclosure, disruption, modification, or destruction.

Future Attacks

• Attacks are inevitable because technology evolves, new vulnerabilities arise, and attackers are constantly finding new ways to exploit systems.

Man-in-the-Middle Attack Goal

• The main goal of a man-in-the-middle attack is to intercept communication between two parties and potentially steal sensitive information.
