Social engineering attacks involve manipulating individuals into divulging confidential information or performing actions that compromise security. The fake offer for a free music download is a classic example of social engineering, where attackers lure users with a tempting offer to trick them into providing personal information or downloading malware.

Application whitelisting/blacklisting is a technology used to control which applications are allowed to execute on a company’s corporate PCs. Whitelisting allows only approved applications to run, while blacklisting prevents specific applications from running. This approach is effective for managing application usage across an enterprise.

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.

 The attack surface is the sum of all paths for data into and out of the environment, such as network interfaces, applications, services, protocols, ports, and user accounts. The attack surface represents the exposure of the environment to potential threats and attacks. A vulnerability is an exploitable weakness in a system or its design that can allow an attacker to compromise the system or its data. A vulnerability is a subset of the attack surface, as not all paths for data are vulnerable. References: [Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Module 1: Security Concepts]

 In the context of a cybersecurity breach, attribution involves identifying the responsible party. Since the external USB device was not found, the focus shifts to the actions performed by the receptionist. Analyzing these actions can provide insights into how the breach occurred and may help in attributing the incident to the threat actor

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 the context of public key infrastructure (PKI), a trusted certificate authority (CA) is responsible for issuing digital certificates that verify a digital entity’s identity on the internet. The CA acts as a trusted third party between the user (in this case, tom0411976943) and the recipient (dan1968754032), ensuring that the public keys are indeed who they claim to be. The CA verifies the identity of the users and then issues a certificate containing the public key and a variety of other identification information. The trusted CA can then vouch for the authenticity of each user to the other.

 Full packet capture requires the largest amount of storage space because it involves recording all packets that pass through a network, including all headers and payloads. This type of data collection is comprehensive and allows for detailed analysis, but due to the volume of data it encompasses, it demands significant storage capacity1.

References := The Cisco Secure Network Analytics Data Store Design Guide discusses the storage requirements for different types of network data collection, highlighting the substantial storage needs for full packet captures1.

 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

 Rule-based detection is a type of intrusion detection system (IDS) that uses predefined rules or signatures to identify malicious or suspicious activity. Rule-based detection can provide proof of a user’s action, such as an attempt to exploit a known vulnerability or execute a malicious command. Rule-based detection can also provide a high level of accuracy and specificity, but it requires constant updates and maintenance of the rules or signatures. References: https://learningnetworkstore.cisco.com/on-demand-e-learning/understanding-cisco-cybersecurity-operations-fundamentals-cbrops-v1.0/CSCU-LP-CBROPS-V1-028093.html (Module 4: Attack Methods, Lesson 4.2: Attack Techniques)
