Behaviour-based Virus Analysis and Detection

Every day, the growing number of viruses causes major damage to computer systems, which many antivirus products have been developed to protect. Regrettably, existing antivirus products do not provide a full solution to the problems associated with viruses. One of the main reasons for this is that these products typically use signature-based detection, so that the rapid growth in the number of viruses means that many signatures have to be added to their signature databases each day. These signatures then have to be stored in the computer system, where they consume increasing memory space. Moreover, the large database will also affect the speed of searching for signatures, and, hence, affect the performance of the system. As the number of viruses continues to grow, ever more space will be needed in the future. There is thus an urgent need for a novel and robust detection technique. One of the most encouraging recent developments in virus research is the use of formulae, which provides alternatives to classic virus detection methods. The proposed research uses temporal logic and behaviour-based detection to detect viruses. Interval Temporal Logic (ITL) will be used to generate virus specifications, properties and formulae based on the analysis of the behaviour of computer viruses, in order to detect them. Tempura, which is the executable subset of ITL, will be used to check whether a good or bad behaviour occurs with the help of ITL description and system traces. The process will also use AnaTempura, an integrated workbench tool for ITL that supports our system specifications. AnaTempura will offer validation and verification of the ITL specifications and provide runtime testing of these specifications

Application Adaptive Bandwidth Management Using Real-Time Network Monitoring.

Application adaptive bandwidth management is a strategy for ensuring secure and reliable network operation in the presence of undesirable applications competing for a network’s crucial bandwidth, covert channels of communication via non-standard traffic on well-known ports, and coordinated Denial of Service attacks. The study undertaken here explored the classification, analysis and management of the network traffic on the basis of ports and protocols used, type of applications, traffic direction and flow rates on the East Tennessee State University’s campus-wide network. Bandwidth measurements over a nine-month period indicated bandwidth abuse of less than 0.0001% of total network bandwidth. The conclusion suggests the use of the defense-in-depth approach in conjunction with the KHYATI (Knowledge, Host hardening, Yauld monitoring, Analysis, Tools and Implementation) paradigm to ensure effective information assurance

Predicting Global Internet Instability Caused by Worms using Neural Networks

Student Number : 9607275H - MSc dissertation - School of Electrical and Information Engineering - Faculty of Engineering and the Built EnvironmentInternet worms are capable of quickly propagating by exploiting vulnerabilities of hosts that have access to the Internet. Once a computer has been infected, the worms have access to sensitive information on the computer, and are able to corrupt or retransmit this information. This dissertation describes a method of predicting Internet instability due to the presence of a worm on the Internet, using data currently available from global Internet routers. The work is based on previous research which has indicated a link between the increase in the number of Border Gateway Protocol (BGP) routing messages and global Internet instability. The type of system used to provide the prediction is known as an autoencoder. This is a specialised type of neural network, which is able to provide a degree of novelty for inputs. The autoencoder is trained to recognise “normal” data, and therefore provides a high novelty output for inputs dissimilar to the normal data. The BGP Update routing messages sent between routers were used as the only inputs to the autoencoder. These intra-router messages provide route availability information, and inform neighbouring routers of any route changes. The outputs from the network were shown to help provide an early warning mechanism for the presence of a worm. An alternative method for detecting instability is a rule-based system, which generates alarms if the number of certain BGP routing messages exceeds a prespecified threshold. This project compared the autoencoder to a simple rule-based system. The results showed that the autoencoder provided a better prediction and was less complex for a network administrator to configure. Although the correlation between the number of BGP Updates and global Internet instability has been shown previously, this work presents the first known application of a neural network to predict the instability using this correlation. A system based on this strategy has the potential to reduce the damage done by a worm’s propagation and payload, by providing an automated means of detection that is faster than that of a human

Dampak Keberadaan Industri Kelapa Sawit Terhadap Tata Lingkungan Permukiman di Desa Kumasari Kabupaten Mamuju Utara

Keberadaan sektor industri pada kawasan permukiman dapat menjadi penggerak perekonomian masyarakat setempat, namun keberadaan sektor industri tidak selamanya memberikan dampak positif saja, melainkan memiliki dampak negatif terhadap masyarakat sekitar. Desa Kumasari adalah salah satu desa yang berada di kawasan industri kelapa sawit, keberadaan industri di desa tersebut memberikan dampak pada kondisi lingkungan permukiman. Penelitian ini bertujuan untuk mengetahui dampak keberadaan industri kelapa sawit terhadap tata lingkungan permukiman di Desa Kumasari dengan cara melakukan observasi lagsung di lapangan dengan mengunakan metode mixed methods (kualitatif-kuantitaif) dan analisis mengunakan metode Analisis pembobotan. Dari hasil penelitian di ketahui bahwa keberadaan industri kelapa sawit di Desa Kumasari sangat berpengaruh terhadap kondisi lingkungan dan infrastruktur desa tersebut di antaranya yaitu dengan berdirinya industri tersebut kondisi jalan berdebu dan berlubang yang di timbulkan dari aktifitas kendaraan berat yang mengakut buah kelapa sawit dari perkebunan ke lokasi industri. Kondisi drainase dan sampah juga membuat keadaan desa semakin buruk dibuktikan dengan sampah yang dibuang kesungai membuat aliran meluap dan menyebabkan banjir yang melanda sebagian titik rumah warga jika musim penghujan datang. Selain berdampak negatif dampak positif juga dirasakan masyarakat sekitar dengan adanya MCK yang layak disetiap rumah warga dan meningkatnya sarana air bersih
