Organizations use various techniques to detect an intrusion and trace it back to its source. Scanning and analysis tools are used to detect malicious activity on a network. Once the activity has been detected, organizations can use various techniques to trace the activity back to its source. These techniques include network forensics, log analysis, and Packet Capture (PCAP).
Tracing an attacker's path back to its source is not an easy task. There are a number of tools, both commercial and open source, that can be used to help in this process. The most important factor is to have good logs that have not been tampered with. Once an incident has been detected, the following tools can be used for further analysis:
1. Netstat: Netstat is a command-line network utility that can be used to view all outgoing and incoming network connections on a system. This can be helpful in identifying which systems might be communicating with an attacker.
2. Wireshark: Wireshark is a free and open-source packet analyzer. It can be used to capture and analyze network traffic in order to find suspicious activity.
3. tcpdump: Tcpdump is a command-line packet analyzer that can be used to capture and analyze network traffic.
4. Nmap: Nmap is a network exploration tool that can be used to scan for open ports and services on a system.
5. Whois: Whois is a query and lookup service that can be used to obtain information about a domain or IP address.
By using a combination of these tools, it is possible to detect an intrusion and trace it back to its source. However, it is essential to note that this is not an easy task and requires a great deal of experience and expertise.
