CyberOps Associate 200-201 Syllabus Exam Questions Answers

 Sliding window anomaly detection is a technique used in cybersecurity to identify unusual patterns or behaviors that deviate from the norm. It involves analyzing segments of data over a period of time, referred to as a ‘window,’ and comparing them against typical patterns. Anomalies are detected when observed behaviors significantly differ from expected patterns, indicating potential security incidents or issues that require further investigation. References: An adaptive sliding window for anomaly detection of time series in wireless sensor networks

SIEM (Security Information and Event Management) systems are designed to collect, correlate, and analyze security event data from various sources to provide insights into potential security issues. They raise alerts when detecting suspicious activities. SOAR (Security Orchestration, Automation, and Response) systems, on the other hand, focus on automating and orchestrating incident response processes. They automate investigation path workflows and reduce the time spent on alerts by executing predefined actions and workflows in response to security events or incidents. References: The differences between SIEM and SOAR are highlighted in various cybersecurity resources, including those provided by Palo Alto Networks and Exabeam, which explain that while SIEM primarily focuses on collecting and analyzing security event data, SOAR extends these capabilities through automation, orchestration, and predefined incident response playbooks

In a PCAP file, which is used to capture network packets, each packet contains various pieces of information that can be analyzed. The source and destination addresses refer to the IP addresses of the sender and receiver of the packets. The source and destination ports refer to the port numbers used for the communication, with common ports like 443 indicating HTTPS traffic. The network protocol here is TCP, which is responsible for establishing a connection and ensuring the delivery of packets. The transport protocol is IPv4, which is the underlying protocol for routing packets across the network. Lastly, the application protocol is TLS v1.2, which is used for secure communication over the internet.

References := The Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) course material covers the analysis of network traffic and the interpretation of PCAP files, which includes identifying the different elements within a packet capture1.

 During the negotiation phase of the TLS handshake, the client sends a “ClientHello” message to the server which includes information about TLS versions it supports, cipher-suites it supports and suggested compression methods. This initiates communication protocols for secure connection. References := Cisco Cybersecurity source documents or study guide
