M3A1 Initially, administrators conducted system intrusion detection by personally sitting in front of a console and monitoring all user activity. They would observe behaviors, for instance, a user being on vacation but someone logging into their account or seldom used peripheral devices all of a sudden becoming active. This form of intrusion detection may have worked at the time but it provided no scalability. The next step in intrusion detection technology was audit logs. These logs were printed daily on large fan folded paper and reviewed by system administrators. The logs would then be reviewed for suspicious activity. As time went on, the stacks became excessively large and manually reviewing the logs became too arduous. So observing an intrusion in progress was practically impossible. As technology advanced, the logs would be available online and programs were created to analyze and interpret the data. However, these programs were slow and intensive at computing the data that they had to be run during off hours. As a result, intrusions were …show more content…
These warnings can help users alter their installation’s defensive posture to increase resistance to future attacks. An intrusion detection system is comparable to a burglar alarm system. The car locks to protect the vehicle from theft. In the event someone compromises the lock, the burglar alarm detects this compromise and alarms the owner. The goal seems simple but the task proves to be difficult because intrusion technology doesn’t really detect intrusions, it just identifies evidence that an intrusion occurred at real-time or after the fact. Currently, there are two main intrusion detection technologies being used by organizations. These are network-based and host-based intrusion detection
Explain how the management of human, physical and technological resources can improve the performance of a selected organization.
For this final paper, I would like to discuss the historical failures that came into light when Mr. Clifford Stoll (the author of “Cuckoo’s Egg: Tracking a spy through the Maze of Computer Espionage” book) stumbled upon a $ 0.75 accounting error and the revelations that followed, its potential findings, risks and costs associated and why it is important to address and fix those security holes. Cuckoo’s Egg is an interesting read and the author was successful in presenting to his readers the picture of beginning of Internet days (arpanet, then), network practices then. Despite of the fact that this book describes a real incident that in 1980’s, some of the findings are relevant and torment us even today.
The anti-social behaviour act was made in 2003. The reason for why this was made was to make the rules of anti-social behaviour better and work more efficient also to do the same with the fixed penalty notices. The rules of this act is no one that is under the age of 16 is allowed to buy spray paint due to graffiti on private properties, no group of teenagers are allowed to do anything wrong to the public and also no public drunkenness which can lead to people disturbing the peace. An example for this could be the ASBO’s.
IDS is a device or software application that monitors a network for an unauthorised attack.
The usage of computer is not that hard to have incorporated into your daily living and needs.It does require some basic skills that user must have some general knowledge about features,once the device is up and running.But, the device from the manufacturer does come with a preload password manager.The device comes with some other device that you have like a mouse keyboard and hard drive as well as a monitor.The device has a wealth of possibilities that the owner could incorporate the device to be used for. The computer is so huge in the information technology and system division it requires that each user has some sought of protection in order to provide some sought of blockage barrier against criminal activity.
The Aim Higher College’s system administrators and network engineers have described seeing some strange behaviors such as high levels of traffic from many hosts that are causing system outages. The web servers of the college have been shutting down frequently by this traffic, it must be from a hacker group trying to attack the school with malicious software. I will review the network traffic from the college’s intrusion detection system and use an intrusion prevention system to block off these threats from the hackers.
Nowadays, most of the web, email, database and fileservers are Linux servers. Linux is a UNIX system which implies that it has solid compatibility, stability and security features. Linux is used for the mentioned environments because these services require high security. Further, an increase of attacks on these servers can be observed. Additionally, the methods to prevent intrusions on Linux machines are insufficient. Further, the analysis of incidents on Linux systems are not considered appropriately (Choi, Savoldi, Gubian, Lee, & Lee, 2008). It can also be observed that a lot of investigators do not have experience with Linux forensics (Altheide, 2004).
In 1980, James Anderson’s paper, Computer Security Threat Monitoring and Surveillance, bore the notion of intrusion detection. Through government funding and serious corporate interest allowed for intrusion detection systems(IDS) to develope into their current state. So what exactly is IDS? An IDS is used to detect malicious network traffic and computer usage through attack signatures. The IDS watches for attacks not only from incoming internet traffic but also for attacks that originate in the system. When a potential attack is detected the IDS logs the information and sends an alert to the console. How the alert is detected and handled at is dependent on the type of IDS in place. Through this paper we will discuss the different types of IDS and how they detect and handle the alerts, the difference between a passive and a reactive system and some general IDS intrusion invasion techniques.
Incident response is usually one of those security areas that tend to be impromptucompanies don't think about it until they have to. But that needs to change. In this paper I will discuss five steps - identification, containment, eradication, and recovery and follow up a business use to effectively response to a security threat and I will suggest four actions -use encryption and passwords, e-mail protection, install antivirus software, install workstation firewalls a businesses can take to effectively prevent a security incident in the future.
Although Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) have been grouped together here (IDPS), there are distinctions between them. On the most basic level, both will monitor the network...
Computer security is the process of preventing and detecting unauthorized use of your computer. Prevention measures help to stop unauthorized users or intruders from accessing any part of a computer system. Detection helps one to determine whether or not someone attempted to break into a computer system, if they were successful, and what they may have done.
Steve Forrester, Vice-President of Sales at Jacket-X reconnected his company laptop to the corporate local area network (LAN) without being subsequent to the company’s policy; the Intrusion Detection System (IDS) alerted the ISO Jack Wilson that a malicious worm was attacking the server. The worm immediately ex...

INTRODUCTION: Good morning, my name is your name and my period of instruction is on the M252 81mm Mortar. We will cover some basic mortar knowledge including nomenclatures, rates of fire, and weight. We will also cover the mission of an 81mm mortar platoon and how that platoon is configured. The purpose of this period of instruction is to provide you with basic information and working knowledge of the 81mm mortar.
Few of the security suggest that less money should be spent on antivirus and other similar security software. It is debated that it is better to invest that money over other areas like analyzing the huge amount of data over the computer network, which proves a huge surface area for attack. It is believed that investing on learning on how the cyber attacks are conducted and changing the business in order to have relevant protection from such attacks is a more viable option. One of the alternate ways for protection is to know about cyber attacks...
