This paper presents an overview of the security issues of the Internet. It reviews the security issues and challenges of both the IPv4 (Internet Protocol version 4) and IPv6 (Internet Protocol version 6) protocol stacks, currently in use. The weaknesses giving birth of the security challenges are mentioned. Security improvements of the Internet use in the newly defined IPv6 are discussed. Security issues arising of the IPv4-IPv6 dual stack protocols are also included in the discussion. Some security-related functionality of the new IPv6 protocols are reviewed .It is seen that the security of the Internet is not a current concern only; it existed before, and will continue to exist in the future. As we know, nowadays, security requirements have become more critical because, small, medium and big enterprises all are using the Internet and the Internet-like infrastructure for their day-to-day businesses. As business incurs money involving profit and loss, so we may say that a continuous war will be on between the Internet-based system managers and the rivals including malicious attackers. It is recommended that the network/system administrators should remain aware of the new flaws using the Internet and immediately get the patches to keep the system secure. Incidentally, our discussion is confined to the technical aspects of security issues of the Internet The challenges to the financial, social and ethical aspects of the Internet security could not be included due to limitation of paper size.
