There are several freeware or shareware intrusion detection systems as well as intrusion detection systems.
Here are some of the open source intrusion detection systems:
The first commander of the Department of Defense has directed the operations of the network for the crackdown on security. According to a recent article by NetworkWorld on January 16.2006, Lt. General Charles Croom is quoted as saying: “The attacks come from everywhere and they are better.” His speech was the keynote address at the Department of Cyber Defense Conference held on Crime January 9 – 14, 2005 in Clearwater, Florida. The event is sponsored by the Defense Cyber Crime Center and the Joint Task Force. More than 500 specialists in computer crime The FBI and the military attended the event.
The repression is linked to a recent arrest of a “Computer Virus Broker” named Jeanson James Ancheta. The further investigation, the Department of Justice press release of November 3rd, 2005 offers the following information about this incident, ” In the first prosecution of its kind in the nation, a well known member of the “botmaster underground” has been indicted on Federal Charges in order to benefit from the use of “botnets” – armies of computers that are under the control of the botmaster and are used to launch destructive attacks or to send huge quantities of spam across the Internet.
Jeanson James Ancheta, 20, of Downey, California, was arrested this morning by special agents with the Federal Bureau of Investigation. Ancheta was indicted yesterday in two conspiracies, as well as charges of attempting to cause damage to protected computers, causing damage to computers used by the federal government in national defense, access to protected computers without the authorization to commit fraud and money laundering. ”
The press release goes on to describe details of the scheme which clearly show why the Department of Defense is concerned (for more information, go to: http://www.usdoj.gov/criminal/cybercrime/ anchetaArrest.htm)
“Ancheta was an affiliate of several companies of advertising services, business and paid him a commission based on the number of facilities. To avoid detection by network administrators, security analysts and law enforcement, Ancheta could vary the download times and rates of the adware installations. When companies hosting Ancheta adware servers discovered the malicious activity, Ancheta redirected his botnet armies to a different server he controlled to pick up adware. To generate the approximately $ 60,000 he received in advertising affiliate products, Ancheta caused the surreptitious installation of adware on approximately 400,000 compromised computers. Ancheta used the proceeds from affiliate advertising he earned to pay between other things, the large number of servers used to conduct its programs.
Ancheta used programs powerful enough to cause the infection of computers at the Weapons Division of the United States Naval Air Warfare Center in China Lake, as well as computers belonging to the Defense Information Systems Agency, a component of the U.S. Department Defense. Both networks are used exclusively by the federal government for national defense. After being arrested this morning at the FBI office in Los Angeles, Ancheta was transported to the United States District Court in Los Angeles. It is unclear if he made his first court appearance this afternoon or tomorrow. Ancheta is charged with two counts of conspiracy, two counts of attempted transmission of code to a protected computer, two counts of transmission of code to a government computer, five counts of protecting access to a computer to commit fraud and five counts of money laundering. Count 17 of the indictment seeks forfeiture of more than $ 60,000 in cash, a BMW automobile and computer equipment that the indictment are the proceeds and instrumentalities of Ancheta illegal activity. ”
Some of the latest news. Ancheta pleaded guilty to conspiracy to violate anti-spam and abuse laws, and fraud and serve 4-6 years in prison under the plea agreement – plus heavy fines.
Intrusion Detection System (IDS) are a necessary part of any strategy for enterprise security. What are Intrusion Detection Systems? CERIAS, The Center for Education and Research in Information Assurance and Security, defines it thus:
“The purpose of an intrusion detection system (or IDS) is to detect unauthorized access or misuse of a computer system. Intrusion detection systems are like the anti-theft alarms for computers. They sound alarms and sometimes even take corrective action when an intruder or abuser is detected. Many intrusion detection systems have been developed but the detection schemes generally fall into one of two categories, detection anomaly or misuse detection. detectors to search for abnormalities in behavior that deviates from normal system use. Misuse detectors look for behavior that matches a known attack scenario. A lot of time and money ‘ efforts have been invested in intrusion detection, and this list provides links to many sites that deal with some of these efforts “(http://www.cerias.purdue.edu/about/history/coast_resources / intrusion_detection / )
There is a sub-category of intrusion detection systems called systems intrusion detection system (NIDS). These systems control packets on the network and son looking for suspicious activity. Network intrusion detection systems can control multiple computers at once on a network, while other intrusion detection systems may monitor a lone computer.
Who is out of your system?
A common misconception of software hackers is that it is usually people outside your network who break into your systems and cause chaos. The reality, especially for workers in the enterprise, is that insiders can and, in general, responsible for most security breaches. Insiders often impersonate people with more privileges then themselves to gain access to sensitive information.
How do intruders break into your system?
The simplest and easiest to break, is to let someone have physical access to a system. Despite best efforts, it is often impossible to stop once they have physical access to a machine. Also, if someone has an account on a system already at a low level of permission, another way to break is to use tricks of the trade privileges granted to senior level in the holes in your system . Finally, there are many ways to access their systems, even if working remotely. Remote intrusion techniques have become more complex and difficult to combat.
How can we stop intrusions?
There are several freeware / shareware intrusion detection systems as well as intrusion detection systems.
Open Source Intrusion Detection System
Here are some of the open source intrusion detection systems:
AID (http://sourceforge.net/projects/aide) self-described as “AIDE (Advanced Intrusion Detection Environment) is a free replacement for Tripwire. It does the same things as the semi-free Tripwire and more. There are other free alternatives available, so why build a new one? All other replacements do not achieve the level of Tripwire. And I wanted a program that transcends the limitations of Tripwire.
File System Saint (http://sourceforge.net/projects/fss) – Self-described as “the file system is a lightweight host St. intrusion detection system based on the priority on speed and ease of use. ”
Snort (www.snort.org) self-described as “Snort ® is a source network intrusion prevention and detection system using a rule-based language, combining the benefits of signature, protocol and methods ‘anomaly based inspection. With millions of downloads to date, Snort is the most widely deployed intrusion detection and prevention technology worldwide and has become the de facto standard for the industry. ”
