The -sP option in Nmap is used for host discovery without port scanning, which helps in identifying live hosts without triggering portscan alerts on IDS devices. It sends an ICMP echo request, a TCP SYN packet to port 443, a TCP ACK packet to port 80, and an ICMP timestamp request to each target IP address and waits for a response. Any responses are considered as indications of a live host. References := Cisco Cybersecurity Operations Fundamentals - Module 5: Endpoint Threat Analysis and Computer Forensics

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 certificate that 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

 Availability is one of the three pillars of the CIA triad, a model that defines the principles of information security. Availability describes the concept of data consistently and readily being accessible for legitimate users. Availability ensures that the network and systems are operational and resilient to disruptions, such as denial-of-service attacks, hardware failures, or natural disasters. Availability also involves maintaining backup and recovery procedures, load balancing, and redundancy mechanisms. References:

The exhibit shows “HKEY_LOCAL_MACHINE,” which is a Windows Registry hive. The registry is a database used to store low-level settings for the operating system and for applications that opt to use the registry. The other options are not related to the exhibit, as they are either a part of the Windows Certificate Manager, a naming convention for Windows PowerShell commands, or a component of the Windows Services Manager. References := Cisco Cybersecurity

 In TCP/IP networking, the ACK flag is used to acknowledge the receipt of a packet. It’s a way to confirm that the previous packets have been received and that the connection is proceeding as expected. The RST flag, on the other hand, is used to reset the connection. It is sent if a segment arrives which is not intended for the current connection, or if a connection request is to be denied. Essentially, the ACK flag is about maintaining the established connection, while the RST flag is about aborting connections that are not valid or are no longer needed123.

A phishing attack often involves sending emails that appear to be from reputable sources with the goal of inducing individuals to reveal personal information, such as passwords and credit card numbers. In this case, the email with the subject “price deduction” containing a malicious attachment is designed to trick the recipient into opening the attachment, which can then execute harmful software on their device

When analyzing a pcap file, data encryption can pose a significant challenge in terms of visibility. Encrypted data cannot be easily inspected, which means that the analyst may not be able to view the contents of the network packets to detect suspicious activity.

References: The answers are based on the general knowledge of host-based firewalls and the challenges faced during the analysis of pcap files in cybersecurity, as outlined in Cisco’s cybersecurity documentation and resources.
