This type of analysis is deterministic because it assigns fixed values to the scenario and calculates the expected outcomes based on those values. Deterministic analysis does not account for uncertainty or randomness in the scenario.Reference: https://learningnetworkstore.cisco.com/on-demand-e-learning/understanding-cisco-cybersecurity-operations-fundamentals-cbrops-v1-0/CSCU-LP-CBROPS-V1-028093.html (Module 3, Lesson 3.1.2)

Encryption allows the user to make the data incomprehensible without a specific key, certificate, or password. Encryption is a method of transforming data into a format that only authorized parties can access. Encryption can be used to protect data in transit or at rest from unauthorized access or modification.Reference: https://learningnetworkstore.cisco.com/on-demand-e-learning/understanding-cisco-cybersecurity-operations-fundamentals-cbrops-v1-0/CSCU-LP-CBROPS-V1-028093.html (Module 4, Lesson 4.1.1)

Encryption is challenging to security monitoring because it can be used by threat actors as a method of evasion and obfuscation. Encryption can prevent security devices from inspecting the content or payload of the network traffic, making it difficult to detect malicious activity or signatures. Encryption can also hide the source and destination of the traffic, making it hard to trace the origin or destination of the attack.Reference: https://learningnetworkstore.cisco.com/on-demand-e-learning/understanding-cisco-cybersecurity-operations-fundamentals-cbrops-v1-0/CSCU-LP-CBROPS-V1-028093.html (Module 4, Lesson 4.1.1)

The lack of data visibility needed to detect the attack is caused by the threat actor gaining access to the system by known credentials. This means that the threat actor either obtained the employee's username and password through phishing, social engineering, or other means, or used a compromised account that had legitimate access to the system. This would explain why there were no suspicious logs, alerts, or failed login attempts, as the threat actor appeared to be a normal user.Reference: https://learningnetworkstore.cisco.com/on-demand-e-learning/understanding-cisco-cybersecurity-operations-fundamentals-cbrops-v1-0/CSCU-LP-CBROPS-V1-028093.html (Module 2, Lesson 2.1.2)

In this scenario, the threat actor refers to the individuals or entities responsible for the attack that resulted in a breach of assets and sensitive information. The receptionist received a threatening call but did not take action, leading to an actual breach within 48 hours.Reference: The explanation is inferred from general cybersecurity knowledge as specific details are not provided in the Cisco Cybersecurity documents linked.

A vulnerability refers to a weakness or flaw in a system that can be exploited by threats (such as hackers or malware) to gain unauthorized access, cause damage, etc. Threats exploit these vulnerabilities to impact the confidentiality, integrity, or availability of information and systems.Reference:Cisco Cybersecurity Associate

Social engineering techniques often involve manipulating individuals into divulging confidential information or performing actions that compromise security. Phishing involves sending fraudulent messages (often emails) that appear to be from reputable sources with the goal of stealing sensitive data or installing malware. Pharming redirects the traffic of a legitimate website to another fraudulent website without the user's knowledge, aiming to collect the user's credentials.Reference:=Cisco Cybersecurity Source Documents

The output indicates that several ports are open on the server with IP address 172.18.104.139, including port 22/tcp for SSH, port 25/tcp for SMTP, port 110/tcp for POP3, and port 143/tcp for IMAP - these are typically associated with a web server.Reference:=Cisco Cybersecurity Source Documents

A Certificate Authority (CA) is responsible for issuing digital certificates to validate the identity of the certificate holder and provide a means to establish secure communications over networks like the Internet.Reference:=Cisco Cybersecurity Source Documents
