Essay Intrusion Detection Systems

Why would an information systems security practitioner want to see network traffic on both internal and external network traffic?

tools will help to detect intrusions and other suspicious activities on the network. The third challenge is to improve the

For the purpose of this assignment snort will be used as intrusion detections systems which is an open source IDS, snort has the ability to monitor traffics in real time and packet locking its also inspecting each packets as they enters into the network, Snort can be used as packet sniffer to analyse the network traffic in order to detect any bizarre looking packets or payloads which might have malicious data in it. Snort can also detect payloads attacks against the network or host system including but not limited to stealth port scan, and buffer overflows.

Where coursework, other than a Master’s dissertation or Master’s project, is handed in late and there are no valid mitigating circumstances, the

KDDCup99 dataset was introduced at the Third International Knowledge Discovery and Data Mining Tools Competition which was held by DARPA in 1999 .KDDCup99 is a refined data set from DARPA 1998 dataset as it contains only network data[3]. KDDCup99 is commonly used developers and implementers of new IDS to evaluate their systems. IDS systems take the KDDCup99 dataset as an input to train ,test the system and check performance of the IDS in classifying and detecting attack records. KDDCup99 dataset is used by most researchers because it contains 22 different attack types which could be classified into four main attack categories of the network discussed in the previous section. The full DARPA dataset consists of relatively 4,900,000 lines of connection vectors where each single connection vectors consists of 41 features and is marked as either normal or an attack, with exactly one particular attack type [38]. Among the 41 features of the connection, only sixteen significant attributes are considered which are: A1,A5,A6,A8, A9, A10, A11, A13, A16, A17, A18, A19, A23, A24, A32, A33[38] The KDD 99

Network Intrusion Detection: Software exists to watch traffic on your network to search for malicious intent. Is an Intrusion Detection System going to be implemented? An IDS is not a fire and forget type system. It requires constant monitoring. Smaller organizations will be overwhelmed by the amount of information it produces.

When the GCU gathers evidence for later use for the court, sources of evidence can be monitored to detect threatened incidents in a timely manner. The GCU employee’s needs to be aware of suspicious transaction related to any activity in the customer account. Securing intrusion detection systems (IDS) components are important because IDS are often targeted by attackers that want to prevent the IDS from detecting attacks or want to gain access to sensitive information on the IDS, such as host configurations and known vulnerabilities. In monitoring and auditing, the types of activities recognized as suspicious will be different from different business needs. For example, a forensic accountant may look for specific patterns of financial data to trigger suspicion of fraud or theft. A suspicious event might be multiple emails on a sensitive subject from a person that is not involved in the subject. Recommend resources that can be used

The fifth domain is the WAN domain. In this domain, the network security application that is apart of it is the intrusion detection system/intrusion prevention system (IDS/IPS). This device monitors the system for malicious activities and reports it back (Kim & Solomon, 2012). The WAN Domain connects to remote locations and using the IDS/IPS is crucial because it will help to remote if any outside activity is trying to access the system that should not be.

Two weaknesses were found in regards to the company 's network security. First weakness is a hardware weakness; and another is IDS which not having a Network-based Intrusion Detection System (IDS) in use. The recommended solutions are to show an AAA server for user authentication and authorization to company resources, and deploy a combination Host and Network-based IDS for overall monitoring of the company 's enterprise.

The network team is doing its part to recommend updates to the network intrusion detection system. Also the team has setup alerts which will send email to the team when there is a change in the baseline network bandwidth which can be a precursor to an attack. Additional monitoring has been enabled to alert the team when there is administrative access to the firewall. Also the team will work to build resiliency in the network to automatically switch the network to additional circuits when under this type of

The goal of intrusion detection is to monitor network assets, detect anomalous behavior, and identify misuse within a network (Ashoor, Gore, 2011). An intrusion detection system (IDS) is a device or software application that monitors network system activities for malicious activity or policy violations and produces reports to a management station (Kashyap, Agrawal, Pandey, Keshri, 2013), additionally there are three types of IDS:

Network security has changed significantly over the past years. There is more and more data to monitor and analyze in order to detect the activity of your data and systems. Securing a network has many variables. Password authentication, network access, patches, anti-virus protection, intrusion detection, firewall and network monitoring tools are just a few of the things you can do to protect yourself.

Most important security challenge on the Internet is the existence of the large number of compromised machines. Project main aim is to detect the compromised machines

Firewalls is categorized as a preventive control which is used as a defense shield around IT systems to keep intruders and hacking from occurring, whereas, an Intrusion Detection System (IDS) which is categorized as a detective control is used to detect intrusions that have already occurred (Cavusoglu, Mishra, & Raghunathan, 2005). However, IDSs are not
