Indirect evidence is evidence that does not directly prove a fact, but rather implies or infers it from other facts or circumstances. Indirect evidence is also known as circumstantial evidence or corroborating evidence. A video of a suspect entering a data center that was captured on the same day that files in the same data center were transferred to a competitor is an example of indirect evidence, because it does not directly show that the suspect was involved in the file transfer, but rather suggests a possible connection or correlation between the two events. References := Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) v1.0, Module 5: Security Policies and Procedures, Lesson 5.3: Digital Forensics, Topic 5.3.1: Evidence, page 5-24.

A sandbox is a technology on a host that is used to isolate a running application from other applications. A sandbox creates a controlled and restricted environment for the application to execute, limiting its access to system resources and data. A sandbox can prevent the application from spreading malware, stealing information, or causing damage to the host or the network. A sandbox can also be used to test and analyze the behavior of unknown or suspicious applications without risking the security of the host. Application allow list, application block list, and host-based firewall are other technologies on a host that can be used to control or restrict the execution of applications, but they do not isolate them from other applications. References:

The exhibit shows a network diagram with a switch, a router, and two hosts. The switch has a MAC address table that maps the MAC addresses of the connected devices to the corresponding ports. A MAC flooding attack is a type of attack that aims to overload the switch’s MAC address table by sending a large number of frames with spoofed source MAC addresses. This causes the switch to enter a fail-open mode, where it broadcasts all incoming frames to all ports, effectively turning it into a hub. This allows the attacker to sniff the traffic between the hosts and the router, or launch other attacks such as ARP spoofing or man-in-the-middle

The 5-tuple approach consists of protocol, source IP address, source port number, destination IP address, and destination port number to uniquely identify sessions between endpoints on a network. References := Cisco Cybersecurity Source Documents
