During the analysis, the threat intelligence team disclosed a possible threat which went unnoticed when an A .R.T.I.E. employee sent their friend a slide deck containing the personal information of a colleague. The exposed information included employee first and last names, date of birth and employee ID.
What kind of attack occurred?
A data breach occurs when confidential information is accessed or disclosed without authorization. In the scenario described, an employee unintentionally sent out a slide deck containing personal information of a colleague. This incident falls under the category of a data breach because it involves the exposure of personal data.
In the context of the Dell Security Foundations Achievement, understanding the nature of different types of cyber threats is crucial. A data breach, as mentioned, is an incident where information is accessed without authorization. This differs from:
A ransomware attack (A), which involves malware that encrypts the victim's files and demands a ransom for the decryption key.
An advanced persistent threat , which is a prolonged and targeted cyberattack in which an intruder gains access to a network and remains undetected for an extended period.
A supply chain attack (D), which occurs when a malicious party infiltrates a system through an outside partner or provider with access to the system and its data.
Therefore, based on the information provided and the context of the Dell Security Foundations Achievement, the correct answer is B. Data breach.
The cybersecurity team must create a resilient security plan to address threats. To accomplish this, the threat intelligence team performed a thorough analysis of the A .R.T.I.E. threat landscape. The result was a list of vulnerabilities such as social engineering, zero-day exploits, ransomware, phishing emails, outsourced infrastructure, and insider threats.
Using the information in the case study and the scenario for this question, which vulnerability type exposes the data and infrastructure of A.R.T.I.E .?
A R.T.I.E.'s business is forecast to grow tremendously in the next year, the organization will not only need to hire new employees but also requires contracting with third-party vendors to continue seamless operations. A .R.T.I.E. uses a VPN to support its employees on the corporate network, but the organization is facing a security challenge in supporting the third-party business vendors.
To better meet A .R.T.I.E.'s security needs, the cybersecurity team suggested adopting a Zero Trust architecture (ZTA). The main aim was to move defenses from static, network-based perimeters to focus on users, assets, and resources. Zero Trust continuously ensures that a user is authentic and the request for resources is also valid. ZTA also helps to secure the attack surface while supporting vendor access.
What is the main challenge that ZTA addresses?
Implementing ZTA would address this challenge by:
Ensuring that all users, even those within the network perimeter, must be authenticated and authorized to access any corporate resources.
Providing continuous validation of the security posture of both the user and the device before granting access to resources.
During analysis, the Dell Services team found outdated applications and operating systems with missing security patches. To avert potential cyberattacks, Dell recommends application and operating system hardening measures.
Why is security hardening important for A.R.T.I.E .?
Based on the information in the case study, which security team should be the most suitable to perform root cause analysis of the attack and present the proposal to solve the challenges faced by the A .R.T.I.E. organization?
