As the senior network analyst for a leading fintech organization, you have been tasked with ensuring seamless communication between the firm's global offices. Your network has been built with redundancy in mind, leveraging multiple service providers and a mixture of MPLS and public internet connections.One week after deploying a state-of-the-art Network Performance Monitoring & Diagnostics (NPMD) tool, you notice unusual traffic patterns originating from your European data center and targeting the corporate headquarters in New York. The traffic spikes periodically, heavily utilizing the MPLS link and sometimes saturating the public internet connection, resulting in significant data packet losses and application failures. Your task is to identify the root cause of these traffic anomalies and ensure optimal network performance for all critical business operations. Given this scenario, what could be the primary cause for these traffic spikes, and what should your Immediate course of action be?

Data Backup and Replication The European data center might be running data backup or replication processes during peak business hours. You should liaise with the data center team to reschedule backup operations to non-peak hours and ensure that backup processes are bandwidth-aware. Faulty Network Hardware The network hardware in the European data center, such as routers or switches, might be malfunctioning, causing inconsistent traffic bursts. Diagnosing the hardware, checking for faults, and replacing the faulty equipment should be the immediate action.

MPLS Link Flapping The MPLS link might be experiencing flapping, leading to inconsistent traffic flow. It is crucial to liaise with the MPLS service provider to inspect the link stability and consider a backup link or an alternate route to reroute the traffic.

Unauthorized Application Usage The European data center staff might be using unauthorized applications or services that are consuming massive bandwidth. You should enforce strict Application and Network Access Control policies, and scrutinize the application traffic to restrict non business-critical applications.

ProNet, a leading technology firm, has been dynamically evolving its internal infrastructure to cater to an expanding workforce and changing business needs. The company's current project involves enhancing the overall security of its internal platforms. The company's security team is focusing on a robust access control system. To make the system efficient, it needs to implement a model that would define access based on roles within the organization, where specific roles would have predefined access to certain resources, and the roles can be assigned to multiple users. The aim is to decrease the administrative work involved in assigning permissions and ensure that users gain only the necessary permissions in line with their job functions.Which access control model best suits ProNet's requirement?

Role-Based Access Control (RBAC)

Attribute-Based Access Control (ABAC)

Discretionary Access Control (DAC)

Role-Based Access Control (RBAC)

In a multinational corporation, the IT department Implemented a new network security protocol for their global data centers. This protocol was designed to enhance security measures by incorporating advanced access control principles. The protocol employs a combination of methods to ensure that only authorized personnel can access sensitive data. Recently, an incident occurred where an unauthorized user gained access to confidential data. The security team discovered that the intruder exploited a specific aspect of the access control system. Which aspect of the access control principles, terminologies, and models was most likely exploited?

Discretionary Access Control (DAC). where the resource owner decides on the access permissions.

Attribute-Based Access Control {ABAC), where access decisions are made based on a set of policies and attributes.

Discretionary Access Control (DAC). where the resource owner decides on the access permissions.

Role-Based Access Control (RBAC). where access is given based on the roles within the organization.

Mandatory Access Control (MAC), where access decisions are made based on predefined rules set by the system s administrator.

NexaCorp. an enterprise with a robust Linux infrastructure, has been facing consistent downtimes without any apparent reasons. The company's initial investigation suggests possible unauthorized system-level changes. NexaCorp's IT team realizes that It needs to monitor and analyze system logs more efficiently to pinpoint the cause. What would be the optimal approach for NexaCorp to monitor and analyze its Linux system logs to detect and prevent unauthorized changes?

You are the lead cybersecurity analyst for a multinational corporation that handles sensitive financial data. As part of your network security strategy, you have implemented both an Intrusion Detection System (IDS) and an Intrusion Prevention System(IPS) to safeguard against cyber threats. One day, your IDS alerts you to suspicious activity on the network, indicating a potential intrusion attempt from an external source. Meanwhile, your IPS springs into action, swiftly blocking the malicious traffic before it can penetrate deeper into the network. Based on this scenario, what primarily distinguishes the role of the IDS from the IPS In your network security architecture?

The IDS focuses on identifying suspicious activities and generating alerts, while the IPS actively blocks and mitigates potential threats in real-time.

The IDS primarily uses signature-based detection techniques, while the IPS relies primarily on anomaly-based detection methods.

The IDS operates solely at the network perimeter, while the IPS can also monitor and protect internal network traffic.

The IDS focuses on identifying suspicious activities and generating alerts, while the IPS actively blocks and mitigates potential threats in real-time.

The IDS requires manual intervention for threat mitigation, while the IPS can autonomously respond to threats without human intervention.
