CloudIDS: Cloud Intrusion Detection Model Inspired by Dendritic Cell Mechanism

Cloud Computing Security is a new era of computer technology and opens a new research area and creates a lot of opportunity of exploration. One of the new implementation in Cloud is Intrusion Detection System (IDS).There are problems with existing IDS approach in Cloud environment. Implementing traditional IDS need a lot of self-maintenance and did not scale with the customer security requirements. In addition, maintenance of traditional IDS in Cloud Computing system requires expertise and consumes more time where not each Cloud user has. A decentralized traditional IDS approach where being deployed in current Cloud Computing infrastructure will make the IDS management become complicated. Each user's IDS will not be the same in term of type and configurations and each user may have outdated signatures. Inter VM's communication also become a big concern when we implementing Cloud Computing system where communication between Clouds are not monitored and controlled by the traditional IDS. A specific IDS model for Cloud computing is required to solve these problems. In this paper, we develop a prototype of Cloud IDS inspired by Dendritic Cell mechanism. Experiment result proved that Cloud IDS was able to detect any attempt to attack the Cloud environment. The experiments show that the Cloud IDS model based on Dendritic Cell algorithm able to identify and detect novel threat that targeting Cloud environment

Perkembangan penulisan ḥadīth telah lama berlaku sejak abad ke-2H/8M. Pelbagai metode telah diperkenalkan oleh para ulama dalam menulis karya ḥadīth. Metode tarjīḥ merupakan salah satu metode yang paling kerap diaplikasikan oleh para ulama ḥadīth ketika menulis karya mereka. Keistimewaan yang terdapat pada metode ini menarik minat sejumlah besar pengkarya untuk mengaplikasikan metode ini dalam karya mereka termasuklah al-Kāndahlawi. Al-Kāndahlawi  telah menjadikan metode ini sebagai salah satu metode yang mendominasi karya al-Abwāb Wa al-Tarājim beliau. Metode tarjīḥ beliau dalam karya al-abwāb dan al-tarājim belum diperbincangkan secara tuntas. Justeru, kajian ini dibuat untuk mengenalpasti metode tarjīḥ yang diguna pakai oleh al-Kāndahlawi dalam menghasilkan karya al-Abwāb wa al-Tarājim li Ṣaḥīḥ al-Bukhārī. Kajian ini merupakan kajian analisis kandungan yang menggunakan pendekatan kaedah analisis dokumen dan analisis sejarah dalam proses pengumpulan data. Data-data yang dikumpulkan dianalisis melalui pendekatan deskriptif. Hasil kajian mendapati bahawa al-Kāndahlawi menggunakan lima metode tarjīḥ. Pertama ialah al-tarjīḥ bi muwāfaqah maᶜānī al-Qurān. Kedua, al-tarjīḥ li muṭābaqah al-ḥadīth bi al-kitāb. Ketiga, al-tarjīḥ aḥad al-khabarain bi muwāfaqah al-aqwāl al-ᶜulama. Keempat, al-tarjīḥ bi iᶜtibār al-isnād . Kelima, tarjīḥ bi muwāfaqah dalil ākhar. Implikasi kajian ini adalah pentingnya menyelami metodologi tarjīḥ yang digunakan oleh ulama dalam menulis ḥadīth Nabi SAW. The burgeoning of Hadith recounting and reporting have long been flourishing since in the second Hijriah (8th Century) with profuse methodology introduced by community of renown Islamic scholars, particularly Tarjih methodology which is known to be the most incessantly solicited. The eccentric or distinctiveness of Tarjih methodology, has drawn the recognition of preponderance among scholars including al-Kandahlawi. Tarjih is evidently the pre-eminence premise on which al-Kandahlawi wrote his al-Abwab Wa al-Tarajim. However, the Tarjih methodology in this particular work of his, has not been examined and explained in detail. Therefore, the impetus of this research paper is purposely carried out to illuminate the applicative of Tarjih methodology in producing his work, al-Abwāb wa al-Tarājim li Ṣaḥīḥ al-Bukhārī. In essence, this research is a study of content analysis that employs document analysis method and historical analysis in data accumulating process. The accreted data then, is analysed by means of descriptive analysis. Ramifications of this research paper recognised that al-Kandahlawi has applied five (5) Tarjih methodology as follows, al-tarjīḥ bi muwāfaqah maᶜānī al-Qurān, al-tarjīḥ li muṭābaqah al-ḥadīth bi al-kitāb, al-tarjīḥ aḥad al-khabarain bi muwāfaqah al-aqwāl al-ᶜulama, al-tarjīḥ bi iᶜtibār al-isnād and tarjīḥ bi muwāfaqah dalil ākhar.  This research paper strives to impart the importance to appreciate the diverse Tarjih methodology utilised by scholars in interpreting hadiths by Prophet Muhammad s.a.w
