 Statistical detection relies on analyzing data over time to identify patterns and anomalies, without predefined rules. It uses algorithms and statistical models to determine normal behavior and identify deviations. Rule-based detection uses predefined rules or patterns to identify known threats or vulnerabilities, often based on signatures or behaviors associated with specific attacks.

After a breach has been discovered and the immediate threat has been addressed by identifying and removing the threat’s access, the next step according to the NIST SP 800-61 Incident Handling Guide is to recover from the threat. This involves restoring systems to normal operation, confirming that the systems are functioning normally, and applying patches or other remediation measures to prevent similar breaches in the future1.

 A threat represents a potential danger that could exploit a weakness in a system while risk is associated with the potential impact or loss that could occur if a threat exploits a vulnerability in the system. So, option A which states “Threat represents a potential danger that could take advantage of a weakness in a system” is correct. References := Cisco Certified CyberOps Associate Overview

Port scanning is a technique that an attacker uses to discover which network ports are open, closed, or filtered on a target device. By sending packets to different ports and observing the responses, an attacker can identify the services and applications running on the device, as well as potential vulnerabilities that can be exploited. Port scanning is a common reconnaissance activity that precedes an attack. References: Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Cisco, page 2-6; 200-201 CBROPS - Cisco, exam topic 1.1.a

FAT is a file system that organizes and stores data on a disk. However, FAT has a limitation of 4 GB for the maximum file size, which means that any file larger than that will be corrupted. To resolve this issue, the engineer can use FAT32, which is an improved version of FAT that supports files up to 32 GB. Alternatively, the engineer can use other file systems that have higher file size limits, such as Ext4 or NTFS. References := Cisco Cybersecurity Operations Fundamentals, Module 5: Security Policies and Procedures, Lesson 5.1: Data Retention, Topic 5.1.1: Data Retention Policies and Procedures

 Vulnerability refers to a weakness or flaw in a system that can be exploited by threats. Risk, on the other hand, is the potential for loss or damage when a threat exploits a vulnerability. The risk is essentially the impact or consequence of a vulnerability being exploited

Stealthwatch is the technology that an engineer should use to fetch logs from a proxy server and generate actual events based on the data received. Cisco Secure Network Analytics, formerly known as Stealthwatch, provides the capability to configure proxy server logs so that the Flow Collector can receive the information. The Stealthwatch Management Console then displays this information on the Flow Proxy Records page, which includes URLs and application names of the traffic inside a network going through the proxy server1.

The packet capture exhibit shows that the source IP address is 192.168.122.100 and it is sending a packet from source port 50272 to destination port 80 of destination IP address 81.179.179.69 using TCP protocol. The TCP protocol is indicated by the Protocol field which has the value 6. The source and destination ports are indicated by the SrcPort and DstPort fields respectively. The source and destination IP addresses are indicated by the SrcAddr and DstAddr fields respectively. References := Cisco Cybersecurity Operations Fundamentals - Module 3: Network Data and Event Analysis

Social engineering techniques often involve manipulating individuals into divulging confidential information or performing actions that compromise security. Phishing involves sending fraudulent messages (often emails) that appear to be from reputable sources with the goal of stealing sensitive data or installing malware. Pharming redirects the traffic of a legitimate website to another fraudulent website without the user’s knowledge, aiming to collect the user’s credentials. References := Cisco Cybersecurity Source Documents

Threat hunting is a proactive cybersecurity technique that involves searching for indicators of compromise or signs of intrusion within an organization’s network or systems. Unlike automated detection systems, threat hunting is typically carried out by security analysts who use their knowledge and intuition to identify subtle, unusual patterns that may indicate a security breach. The goal of threat hunting is to identify and mitigate threats before they can cause significant damage.
