Exam 37: Implementing Cisco Enterprise Network Core Technologies (ENCOR)

How does Wireshark decrypt TLS network traffic?

A security engineer discovers that a spreadsheet containing confidential information for nine of their employees was fraudulently posted on a competitor's website. The spreadsheet contains names, salaries, and social security numbers. What is the next step the engineer should take in this investigation?

An organization had several cyberattacks over the last 6 months and has tasked an engineer with looking for patterns or trends that will help the organization anticipate future attacks and mitigate them. Which data analytic technique should the engineer use to accomplish this task?

A company recently completed an internal audit and discovered that there is CSRF vulnerability in 20 of its hosted applications. Based on the audit, which recommendation should an engineer make for patching?

Refer to the exhibit. Based on the detected vulnerabilities, what is the next recommended mitigation step?

An organization installed a new application server for IP phones. An automated process fetched user credentials from the Active Directory server, and the application will have access to on-premises and cloud services. Which security threat should be mitigated first?

According to GDPR, what should be done with data to ensure its confidentiality, integrity, and availability?

An engineer receives an incident ticket with hundreds of intrusion alerts that require investigation. An analysis of the incident log shows that the alerts are from trusted IP addresses and internal devices. The final incident report stated that these alerts were false positives and that no intrusions were detected. What action should be taken to harden the network?

Refer to the exhibit. How must these advisories be prioritized for handling?

Refer to the exhibit. Rapid Threat Containment using Cisco Secure Network Analytics (Stealthwatch) and ISE detects the threat of malware-infected 802.1x authenticated endpoints and places that endpoint into a quarantine VLAN using Adaptive Network Control policy. Which method was used to signal ISE to quarantine the endpoints?

A SOC team receives multiple alerts by a rule that detects requests to malicious URLs and informs the incident response team to block the malicious URLs requested on the firewall. Which action will improve the effectiveness of the process?

Refer to the exhibit. An engineer must tune the Cisco IOS device to mitigate an attack that is broadcasting a large number of ICMP packets. The attack is sending the victim's spoofed source IP to a network using an IP broadcast address that causes devices in the network to respond back to the source IP address. Which action does the engineer recommend?

Refer to the exhibit. Where are the browser page rendering permissions displayed?

A customer is using a central device to manage network devices over SNMPv2. A remote attacker caused a denial of service condition and can trigger this vulnerability by issuing a GET request for the ciscoFlashMIB OID on an affected device. Which should be disabled to resolve the issue?

Refer to the exhibit. What is the connection status of the ICMP event?

Refer to the exhibit. Cisco Rapid Threat Containment using Cisco Secure Network Analytics (Stealthwatch) and ISE detects the threat of malware-infected 802.1x authenticated endpoints and places that endpoint into a Quarantine VLAN using Adaptive Network Control policy. Which telemetry feeds were correlated with SMC to identify the malware?

A security expert is investigating a breach that resulted in a $32 million loss from customer accounts. Hackers were able to steal API keys and two-factor codes due to a vulnerability that was introduced in a new code a few weeks before the attack. Which step was missed that would have prevented this breach?

A SOC analyst is notified by the network monitoring tool that there are unusual types of internal traffic on IP subnet 103.921.2239.0/24. The analyst discovers unexplained encrypted data files on a computer system that belongs on that specific subnet. What is the cause of the issue?

What is the purpose of hardening systems?

Refer to the exhibit. An engineer is analyzing this Vlan0392-int12-239.pcap file in Wireshark after detecting a suspicious network activity. The origin header for the direct IP connections in the packets was initiated by a google chrome extension on a WebSocket protocol. The engineer checked message payloads to determine what information was being sent off-site but the payloads are obfuscated and unreadable. What does this STIX indicate?
