Delivery: This step involves transmitting the weapon to the target.

Weaponization: In this step, the intruder creates a malware weapon like a virus, worm or such in order to exploit the vulnerabilities of the target. Depending on the target and thepurpose of the attacker, this malware can exploit new, undetected vulnerabilities (also known as the zero-day exploits) or it can focus on a combination of different vulnerabilities.

Reconnaissance: In this step, the attacker / intruder chooses their target. Then they conduct an in-depth research on this target to identify its vulnerabilities that can be exploited.

The source IP address from an audit log that indicates a session which may have exploited a vulnerability is considered corroborative evidence. This type of evidence supports other evidence that suggests a security breach occurred. In the context of cybersecurity, corroborative evidence can help establish that an attack was carried out and can be used in conjunction with other data points to build a case during an investigation.

References := The Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) training material discusses the types of data needed to investigate security incidents, which includes understanding the role of different types of evidence in building a security incident case1.

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

The analyst is in the detection and analysis phase of the incident response process according to NIST SP800-61. In this phase, events are detected and analyzed to determine whether they constitute incidents that require a response. It involves monitoring security events or data collection, correlation, and analysis of log entries and network flow data, among others. The goal is to identify incidents quickly so that appropriate actions can be taken. References := NIST SP800-61, Computer Security Incident Handling Guide, Section 3.2: Detection and Analysis

A certificate authority (CA) is a trusted entity that issues and manages digital certificates for secure communication over the internet. A digital certificate is a document that contains the public key and the identity of the owner of the key. A CA impacts security by validating the domain identity of the SSL certificate, which is a type of digital certificatethat enables encrypted communication between a web server and a web browser. The CA verifies that the domain name in the certificate matches the domain name of the web server, and signs the certificate with its own private key. The web browser can then verify the signature of the CA and trust the identity of the web server. References := Cisco Cybersecurity Operations Fundamentals, Module 2: Security Monitoring, Lesson 2.3: Cryptography and PKI, Topic 2.3.2: Public Key InfrastructureReference:https://en.wikipedia.org/wiki/Certificate_authority

The containment phase of the incident response lifecycle is focused on limiting the impact of an active incident and preventing it from continuing or spreading further. In this scenario, the organization is experiencing a suspected Distributed Denial-of-Service (DDoS) attack, as indicated by high-volume traffic and degraded application performance.

During containment, the Computer Security Incident Response Team (CSIRT) takes immediate actions such as rate limiting, blocking malicious IP addresses, diverting traffic through scrubbing services, or engaging DDoS mitigation providers. The goal is to stabilize services and ensure that the attack no longer affects business operations. This phase also includes confirming that defensive measures have been successfully applied.

Preparation occurs before an incident and involves planning and readiness activities. Eradication focuses on removing the root cause of the incident, such as disabling attacker infrastructure or removing malware, which is not applicable to most DDoS scenarios. Recovery occurs after containment and involves restoring systems to normal operation and monitoring for recurrence.

Cybersecurity operations documentation clearly defines containment as the phase where ongoing attacks are stopped or controlled. Therefore, containment is the correct answer.
