Discuss the following \”Cyber threats information sharing amongst the government, and private sector will enhance security.\”

The paper is 8 pages. It is about one of the mission areas in the Department of Homeland Security, which is \”Safeguard and Secure Cyberspace.\” The thesis statement is- \”Cyber threats information sharing amongst the government, and private sector will enhance security.\” I do believe that increasing information sharing amongst the government and private sector will strengthen security, this exercise is currently neglected.

The title of the paper can be- \”Enhancing Cybersecurity by Increasing Collaboration Efforts,\” unless you guys have a better title for the content.
