| contents | Computers and computer networks have become integral to virtually every aspect of modern life, with the Internet playing an indispensable role. Organizations, businesses, and individuals now store vast amounts of proprietary, confidential, and personal data digitally. As such, ensuring the security of this data from unauthorized access is critical. Common security measures, such as firewalls, intrusion detection systems (IDS), intrusion prevention systems (IPS), and antivirus software, are constantly evolving to safeguard computer systems and networks. However, these tools primarily focus on defending against external threats, leaving systems vulnerable to insider attacks. Security solutions designed to mitigate risks originating from within the organization are relatively limited and often ineffective. This paper demonstrates how a Local Area Network (LAN) can be covertly exposed to the Internet via an insider attack. Specifically, it illustrates how an external machine can gain access to a LAN by exploiting an unused secondary IP address of the attacked LAN, effectively bypassing existing security mechanisms by also exploiting Hyper Text Transfer Protocol (HTTP). Despite the presence of robust external protections, such as firewalls and IDS, this form of insider attack reveals significant vulnerabilities in the way internal threats are addressed. |
