What protocol is used to collect information about traffic traversing a network?

Contents Packet capture is a vital tool used to keep networks operating safely and efficiently. In the wrong hands, it can also be used to steal sensitive data like usernames and passwords. In this post, we’ll dive into what a packet capture is, how it works, what kind of tools are used, and look at some sample use cases. • • • • • • • Get a Free Data Risk Assessment What is Packet Capture? Packet Capture refers to the action of capturing Internet Protocol (IP) packets for review or analysis. The term can also be used to describe the files that packet capture tools output, which are often saved in the .pcap format. Capturing packets is a common troubleshooting technique for network administrators, and is also used to examine network traffic for security threats. Following a data breach or other incident, packet captures provide vital forensic clues that aid investigations. From a threat actor’s perspective, packet captures might be used to steal passwords and other sensitive data. Unlike active reconnaissance techniques like port scanning , capturing packets can be accomplished without leaving any trace behind for investigators. How Does Packet Capture Work? There’s more than one way to catch a packet! Packet captures can be done from a piece of networking equipment like a router or switch, from a dedicated piece of hardware called a tap, from an analyst’s laptop or desktop, and even from mobile devices. The approach used depends on the end goal. No matter what approach is...

What is the last stage of the Cyber Kill Chain framework? • gathering target information • remote control of the target device • malicious action • creation of malicious payload Explanation: The Cyber Kill Chain describes the phases of a progressive cyberattack operation. The phases include the following: *Reconnaissance *Weaponization *Delivery *Exploitation *Installation *Command and control *Actions on objectives In general, these phases are carried out in sequence. However, during an attack, several phases can be carried out simultaneously, especially if multiple attackers or groups are involved. Exam with this question: Post navigation

https://www.cisco.com/c/en/us/td/docs/security/firepower/60/configuration/guide/fpmc-config-guide-v60/Network_Discovery_Policies.html The network discovery policy has a single default rule in place, configured to discover applications from all observed traffic. The rule does not exclude any networks, zones, or ports, host and user discovery is not configured, and the rule is not configured to monitor a NetFlow exporter. This policy is deployed by default to any managed devices when they are registered to the Firepower Management Center. To begin collecting host or user data, you must add or modify discovery rules and re-deploy the policy to a device. As long the questions indicates that no metada is required the answer is A - https://www.cisco.com/c/en/us/solutions/collateral/enterprise-networks/enterprise-network-security/white-paper-c11-736595.html Netflow are based on metadata - https://learning.oreilly.com/library/view/ccna-cyber-ops/9780134608938/ch04.html#ch04lev1sec1 Opt for A. Cisco doc says Applications can be discovered by "non-NetFlow discovery rules" without Option D You can disable detection of application protocols in discovery rules configured to monitor NetFlow exporters, but not in discovery rules configured to monitor Firepower System managed devices. If you enable host or user discovery in non-NetFlow discovery rules, applications are automatically discovered. https://www.cisco.com/c/en/us/td/docs/security/firepower/630/configuration/guide/fpmc-config-gu...
