A PCAP file can be opened in Wireshark using the File | Open menu option. Wireshark can read in an ASCII hex dump and write the data described into a temporary libpcap capture file for display and analysis. This is useful for packet capture technologies that are unable to output in another of Wireshark's accepted file formats.
The libpcap filetype is a menu option for saving Wireshark captures, but in opening files, Wireshark will attempt to interpret files internally, so it isn't necessary to specify the libpcap format.
Dragging and dropping the PCAP file into Wireshark will also open up a PCAP file. - (1)
The port number is a 2-byte field, and therefore is 4 hexadecimal characters in length. 0080 is the hexadecimal representation of the number 128. 0050 is the port value in Hex for HTTP. The packet bytes pane also...

Overview of this book
Cybersecurity roles have grown exponentially in the IT industry and an increasing number of organizations have set up security operations centers (SOCs) to monitor and respond to security threats. The 210-255 SECOPS exam is the second of two exams required for the Cisco CCNA Cyber Ops certification. By providing you with fundamental knowledge of SOC events, this certification validates your skills in managing cybersecurity processes such as analyzing threats and malicious activities, conducting security investigations, and using incident playbooks.
You'll start by understanding threat analysis and computer forensics, which will help you build the foundation for learning intrusion analysis and incident response principles. The book will then guide you through vocabulary and techniques for analyzing data from the network and previous events. In later chapters, you'll discover how to identify, analyze, correlate, and respond to incidents, including how to communicate technical and inaccessible (non-technical) examples. You'll be able to build on your knowledge as you learn through examples and practice questions, and finally test your knowledge with two mock exams that allow you to put what you’ve learned to the test.
By the end of this book, you'll have the skills to confidently pass the SECOPS 210-255 exam and achieve CCNA Cyber Ops certification.
