Updating intrusion detection report

A system that monitors important operating system files is an example of a HIDS, while a system that analyzes incoming network traffic is an example of a NIDS.

It is also possible to classify IDS by detection approach: the most well-known variants are signature-based detection (recognizing bad patterns, such as malware) and anomaly-based detection (detecting deviations from a model of "good" traffic, which often relies on machine learning).

While the first version examined network traffic and the expansion in development could look at content., Einstein is the product of U. congressional and presidential actions of the early 2000s including the E-Government Act of 2002 which sought to improve U. As described in 2004, its purpose is to "facilitate identifying and responding to cyber threats and attacks, improve network security, increase the resiliency of critical, electronically delivered government services, and enhance the survivability of the Internet." In addition, the program addresses detection of computer worms, anomalies in inbound and outbound traffic, configuration management as well as real-time trends analysis which US-CERT offers to U. departments and agencies on the "health of the domain".

Einstein (also known as the EINSTEIN Program) was originally an intrusion detection system that monitors the network gateways of government departments and agencies in the United States for unauthorized traffic. By 2005, three federal agencies participated and funding was available for six additional deployments.

The software was developed by the United States Computer Emergency Readiness Team (US-CERT), The program was originally developed to provide "situational awareness" for the civilian agencies. Einstein's mandate originated in the Homeland Security Act and the Federal Information Security Management Act, both in 2002, and the Homeland Security Presidential Directive (HSPD) 7, With Fed CIRC at its core, US-CERT was formed in 2003 as a partnership between the newly created DHS and the CERT Coordination Center which is at Carnegie Mellon University and funded by the U. By December 2006, eight agencies participated in Einstein and by 2007, DHS itself was adopting the program department-wide.

A new version of Einstein was planned to "collect network traffic flow data in real time and also analyze the content of some communications, looking for malicious code, for example in e-mail attachments." Einstein 2 will use "the minimal amount" necessary of predefined attack signatures which will come from internal, commercial and public sources.

The Einstein 2 sensor monitors each participating agency's Internet access point, "not strictly...limited to" Trusted Internet Connections, using both commercial and government-developed software.

This policy is effective as of the issue date and does not expire unless replaced by another policy.

Objectives The Intrusion Detection Policy is designed to increase the overall level of security in the enterprise network by actively searching for unauthorized access.The procedural framework outlined in the policy will prevent or detect unauthorized access to organizational data and notify proper personnel of such an incident to preserve the integrity of that data.An intrusion detection system (IDS) is a device or software application that monitors a network or systems for malicious activity or policy violations.The NSA is moving forward to begin a program known as “Einstein 3,” which will monitor “government computer traffic on private sector sites.” (AT&T is being considered as the first private sector site.) The program plan, which was devised under the Bush administration, is controversial, given the history of the NSA and the warrantless wiretapping scandal.Many DHS officials fear that the program should not move forward because of “uncertainty about whether private data can be shielded from unauthorized scrutiny.” DHS assumes that Internet users do not expect privacy in the "To" and "From" addresses of their email or in the "IP addresses of the websites they visit" because their service providers use that information for routing.Incident data and contact information are never shared outside of US-CERT and contact information is not analyzed.
