People Risk Definition: People risk involves the potential for human error or intentional actions that can lead to security incidents1.

Phishing and Social Engineering: The scenario described is typical of phishing, where attackers use seemingly official communications to trick individuals into revealing sensitive information or accessing malicious links1.

Employee Actions: Clicking on the button could potentially lead to the employee inadvertently providing access to the company's systems or revealing personal or company information1.

Dell's Security Foundations Achievement: Dell's Security Foundations Achievement emphasizes the importance of recognizing and minimizing phishing exploits as part of managing people risk21.

Mitigation Measures: Training employees to recognize and respond appropriately to phishing attempts is a key strategy in mitigating people risk1.

In this context, the risk is categorized as 'people' because it directly involves the potential actions of an individual employee that could compromise security1.

Prepare to deal with incidents.

Identify potential security incidents.

Assess incidents and make decisions about...

Contain, investigate, and resolve the incidents.

Make changes to improve the process.

Role of Threat Intelligence: The threat intelligence team is specialized in investigating methodologies and technologies to detect, understand, and deflect advanced cybersecurity threats1.

Root Cause Analysis: They have the expertise to analyze security events, uncover advanced threats, and provide insights into the root causes of cyberattacks1.

Solution Proposal: Based on their analysis, the threat intelligence team can propose solutions to tackle the identified vulnerabilities and enhance the security posture of A .R.T.I.E.1.

Preventive Measures: Their knowledge of the latest developments in the security landscape allows them to recommend proactive measures to prevent future attacks1.

Dell Security Foundations Achievement: The Dell Security Foundations Achievement documents emphasize the importance of threat intelligence in understanding and responding to cybersecurity incidents1.

The threat intelligence team's capabilities align with the requirements of A .R.T.I.E. to address their cybersecurity challenges effectively1.

Signature-Based Detection: This method relies on known signatures or patterns of data that match known malware or ransomware samples1.

Static Analysis: Involves analyzing files without executing them to compare their hashes against a database of known threats1.

Ransomware Sample Hash: A unique identifier for a ransomware sample that can be matched against a database to identify known ransomware1.

Dell Security Foundations Achievement: The Dell Security Foundations Achievement documents likely cover the importance of signature-based detection as part of a comprehensive cybersecurity strategy1.

Effectiveness: While signature-based detection is effective against known threats, it may not detect new, unknown (zero-day) ransomware variants1.

Signature-based detection is a fundamental component of many cybersecurity defenses, particularly for identifying and preventing known ransomware attacks1.

Verified Answer: The type of attack that enables an attacker to read and modify the transmitted data packets and send their own requests to the client is:

C . TCP hijacking

TCP Hijacking Definition: TCP hijacking is a type of cyber attack where an attacker takes control of a communication session between two entities12.

Attack Mechanism: The attacker intercepts and manipulates data packets being sent over the network, allowing them to read, modify, and insert their own packets into the communication stream1.

Impact on Security: This attack can lead to unauthorized access to sensitive data and systems, and it can be used to impersonate the victim, resulting in data breaches and other security incidents1.

Prevention Measures: Implementing security measures such as encryption, using secure protocols, and monitoring network traffic can help prevent TCP hijacking attacks1.

TCP hijacking is particularly relevant to cloud environments where misconfigurations can leave systems vulnerable. It is crucial for A .R.T.I.E. to ensure proper security configurations and adopt measures to protect against such attacks as part of their migration to the public cloud and overall cybersecurity strategy12.

Double Extortion Ransomware: This type of ransomware not only encrypts files but also attempts to encrypt backups and shared, networked, and cloud drives1.

Attack Method: Attackers first exfiltrate sensitive data before encrypting it, then threaten to release the data if the ransom is not paid, hence the term 'double extortion'1.

Impact on Organizations: This method increases the pressure on the victim to pay the ransom, as they face the risk of their sensitive data being published or sold1.

Prevention and Response: Organizations should implement robust backup strategies, including offsite and offline backups, and have an incident response plan that includes dealing with ransomware and data breaches1.

Double extortion ransomware attacks are particularly dangerous because they combine the threat of data encryption with the threat of data exposure, significantly increasing the potential damage to the victim organization1.

Multifactor Authentication (MFA) Definition: MFA requires users to provide multiple forms of identification before gaining access to a resource1.

Security Enhancement: MFA enhances security by combining something the user knows (like a password), something the user has (like a smartphone), and something the user is (like a fingerprint)1.

Protection Against Unauthorized Access: This method protects against unauthorized access by ensuring that even if one factor (like a password) is compromised, the attacker still needs the other factors to gain access1.

Compliance with Regulations: MFA helps organizations comply with various regulations and cloud security controls, which is essential for A .R.T.I.E. as they move to the public cloud1.

Dell's Commitment to MFA: Dell's own security guidelines emphasize the importance of MFA, reflecting their commitment to safeguarding data integrity and providing an additional layer of security during the sign-in process1.

MFA is particularly suitable for A .R.T.I.E.'s scenario because it provides robust security for accessing sensitive resources and data, which is crucial for external users who may not be within the secure internal network1.
