What is the impact of false positive alerts on business compared to true positive?

False-positive alerts are detected by confusion as potential attacks, while true positives are attack attempts identified appropriately.

True positives affect security as no alarm is raised when an attack has taken place, while false positives are alerts raised appropriately to detect and further mitigate them.

True-positive alerts are blocked by mistake as potential attacks, while False-positives are actual attacks Identified as harmless.

False-positive alerts are detected by confusion as potential attacks, while true positives are attack attempts identified appropriately.

False positives alerts are manually ignored signatures to avoid warnings that are already acknowledged, while true positives are warnings that are not yet acknowledged.

What is a difference between data obtained from Tap and SPAN ports?

Tap sends traffic from physical layers to the monitoring device, while SPAN provides a copy of network traffic from switch to destination

Tap mirrors existing traffic from specified ports, while SPAN presents more structured data for deeper analysis.

SPAN passively splits traffic between a network device and the network without altering it, while Tap alters response times.

SPAN improves the detection of media errors, while Tap provides direct access to traffic with lowered data visibility.

Tap sends traffic from physical layers to the monitoring device, while SPAN provides a copy of network traffic from switch to destination

How does agentless monitoring differ from agent-based monitoring?

Agent-based has a possibility to locally filter and transmit only valuable data, while agentless has much higher network utilization

Agentless can access the data via API. While agent-base uses a less efficient method and accesses log data through WMI.

Agent-based monitoring is less intrusive in gathering log data, while agentless requires open ports to fetch the logs

Agent-based monitoring has a lower initial cost for deployment, while agentless monitoring requires resource-intensive deployment.

Agent-based has a possibility to locally filter and transmit only valuable data, while agentless has much higher network utilization

The RST flag approves the connection, and the ACK flag terminates spontaneous connections.

The ACK flag confirms the received segment, and the RST flag terminates the connection.

The RST flag approves the connection, and the ACK flag indicates that a packet needs to be resent

The ACK flag marks the connection as reliable, and the RST flag indicates the failure within TCP Handshake

Refer to the exhibit. An engineer is analyzing a PCAP file after a recent breach An engineer identified that the attacker used an aggressive ARP scan to scan the hosts and found web and SSH servers. Further analysis showed several SSH Server Banner and Key Exchange Initiations. The engineer cannot see the exact data being transmitted over an encrypted channel and cannot identify how the attacker gained access How did the attacker gain access?

by using brute force on the SSH service to gain access

by using the buffer overflow in the URL catcher feature for SSH

by using an SSH Tectia Server vulnerability to enable host-based authentication

by using an SSH vulnerability to silently redirect connections to the local host

by using brute force on the SSH service to gain access

Refer to the exhibit. Which component is identifiable in this exhibit?

Trusted Root Certificate store on the local machine

local service in the Windows Services Manager

An engineer received an alert affecting the degraded performance of a critical server. Analysis showed a heavy CPU and memory load. What is the next step the engineer should take to investigate this resource usage?

Run 'ps -ef' to understand which processes are taking a high amount of resources.

Run 'ps -d' to decrease the priority state of high load processes to avoid resource exhaustion.

Run 'ps -u' to find out who executed additional processes that caused a high load on a server.

Run 'ps -ef' to understand which processes are taking a high amount of resources.

Run 'ps -m' to capture the existing state of daemons and map required processes to find the gap.

What is a difference between an inline and a tap mode traffic monitoring?

Inline mode monitors traffic path, examining any traffic at a wire speed, while a tap mode monitors traffic as it crosses the network.

Inline monitors traffic without examining other devices, while a tap mode tags traffic and examines the data from monitoring devices.

Tap mode monitors traffic direction, while inline mode keeps packet data as it passes through the monitoring devices.

Tap mode monitors packets and t heir content with the highest speed, while the inline mode draws a packet path for analysis.

Inline mode monitors traffic path, examining any traffic at a wire speed, while a tap mode monitors traffic as it crosses the network.

What is the difference between inline traffic interrogation and traffic mirroring?

Traffic mirroring copies the traffic rather than forwarding it directly to the analysis tools

Inline interrogation is less complex as traffic mirroring applies additional tags to data.

Traffic mirroring copies the traffic rather than forwarding it directly to the analysis tools

Inline replicates the traffic to preserve integrity rather than modifying packets before sending them to other analysis tools.

Traffic mirroring results in faster traffic analysis and inline is considerably slower due to latency.
