    Attacker's goals: Attackers aim to compromise network infrastructure to redirect traffic, create illegitimate VPN tunnels, modify ACLs (Access Control Lists) to bypass segmentation, or perform Man-in-the-Middle (MitM) attacks.
    Investigative actions: Identify the source address and machine role (e.g., Is it a known Admin Jump Host or a standard workstation?). Validate if a change request exists for the target network device at the time of the event. Check the connection protocol (SSH/HTTPS vs. insecure Telnet/HTTP) and the port used. Review the login status: Was the authentication successful or failed? Investigate the source machine for network scanning tools or terminal clients (e.g., PuTTY, SecureCRT). Analyze the causality chain: Did a suspicious process launch the connection?. Check if the user associated with the source address has network administration privileges.
