NEW QUESTION # 42
An engineering company's Chief Financial Officer recently fall victim to a phishing scam by responding to an urgent email. The mail appeared to be from a trusted business partner, and it requested sensitive tax information. The incident led to significant financial and reputational damage. To prevent similar occurrences in the future, the security team must implement an effective mitigation strategy. Which mitigation strategy must the security team implement to prevent similar occurrences in the future?
Answer: C
Explanation:
A targeted education campaign directly addresses phishing by training employees, especially high-value targets like executives, to recognize social engineering attempts. While technical controls help, phishing primarily exploits human behavior, so awareness and training are the most effective preventive measures.
NEW QUESTION # 43
After a recent security breach, a financial company is reassessing their overall security posture and strategy to better protect sensitive data and resources. The company already deployed on-premises next-generation firewalls at the network edge for each branch location. Security measures must be enhanced at the endpoint level. The goal is to implement a solution that provides additional traffic filtering directly on endpoint devices, thereby offering another layer of defense against potential threats. Which technology must be implemented to meet the requirement?
Answer: B
Explanation:
When moving security closer to the data, the endpoint becomes the final perimeter. Ahost-based firewallis a software component that runs directly on the endpoint's operating system (Windows, macOS, or Linux).
While the company already has Next-Generation Firewalls (NGFWs) at the network edge, those devices cannot protect endpoints from threats originating within the same local network segment (East-West traffic) or when the device is used outside the corporate office.
Implementing a host-based firewall provides a critical layer ofdefense-in-depth. It allows security administrators to enforce strict inbound and outbound traffic rules based on applications and services specific to that device. For example, it can prevent a compromised laptop from scanning other devices on a public Wi- Fi network. In the Cisco ecosystem, this is often achieved through theCisco Secure Client(AnyConnect) using theNetwork Visibility Module (NVM)or integrated endpoint security suites.
While aDistributed Firewall(Option C) is used for micro-segmentation within data centers/clouds and aWeb Application Firewall (WAF)(Option B) protects servers from web-based attacks, only a host-based firewall meets the requirement for traffic filtering directly on the diverse array of endpoint devices. This approach ensures that even if the network edge is bypassed, the individual host remains hardened against lateral movement and unauthorized communication.
NEW QUESTION # 44
A product manager is focused on maintaining the security integrity of a microservice-based application as new features are developed and integrated. To ensure that known software vulnerabilities are not introduced into the product, it is crucial to implement a robust application security technique. The technique must be applied during the build phase of the software development lifecycle, which allows the team to proactively entity and address vulnerability risks before deployment. Which application security technique must be applied to accomplish the goal?
Answer: A
Explanation:
Container scanning during the build phase ensures that no known software vulnerabilities are introduced into the application. It scans container images for outdated libraries, misconfigurations, and security flaws before deployment, allowing proactive remediation. This directly supports maintaining the security integrity of a microservice-based application.
NEW QUESTION # 45
A developer company recently implemented a testing environment based on Linux operating system. The company needs a technology solution that produces tracing and filtering capabilities in the Linux kernel. Which technology meets these requirements without modifying the kernel source code?
Answer: D
Explanation:
eBPF (extended Berkeley Packet Filter) allows tracing, filtering, and monitoring directly inside the Linux kernel without modifying the kernel source code. It provides deep visibility into system and application behavior, making it ideal for secure and efficient observability in a testing environment.
NEW QUESTION # 46
In preparation for an upcoming security audit, a metal production company decided to enhance the security of container-based services running in a Kubernetes environment. The company wants to ensure that all communications between applications and services are encrypted. The administrator plans to implement mTLS service between application and services to secure the data exchanges. Given the need to manage encryption at scale and maintain efficient communication across the cluster, which network transport technology must be employed?
Answer: D
Explanation:
In modern cloud-native architectures, managing security for hundreds of microservices manually is unfeasible. To implementmutual TLS (mTLS)at scale within a Kubernetes cluster, aService Mesh(such as Istio or Cisco Service Mesh Manager) is the architectural solution of choice. A service mesh provides a dedicated infrastructure layer for handling service-to-service communication without requiring changes to the application code itself.
The service mesh operates by deploying a "sidecar" proxy alongside every service instance. These proxies handle the heavy lifting of identity verification, certificate rotation, and the establishment of encrypted tunnels. This ensures that every data exchange is encrypted and that services only communicate with authenticated peers. While anIngress Controller(Option A) manages traffic entering the cluster andLoad Balancing(Option B) distributes traffic, neither provides the granular, internal encryption framework required for pod-to-pod mTLS.Kubernetes Network Policies(Option C) act as a distributed firewall to allow or deny traffic based on IP/Port but do not handle encryption or cryptographic identity. By choosing a Service Mesh, the company satisfies the audit requirement for end-to-end encryption and pervasive visibility into the application's communication flow, aligning with Cisco's design principles for secure, scalable microservices.
