Improving Defense in Depth for NASA's Mission Network

Defense in depth has been used by NASA's Mission Network in the past and will be used in the future to improve its security posture. This paper discusses the defense building blocks used by NASA which include increasing network capabilities, continued examination of network capabilities, assessment of new technologies and tools, increased security awareness for NASA non-security professionals, and training of the Mission Network security team members. Improvements in policy, business continuity, firewalls, CM, encryption, network architecture, host and network based IDS, host and network based vulnerability assessment tools should be developed. Classes, training and research provide new insight into security measures as NASA works to increase network capabilities while protecting its Mission Network and NASA projects.
