    Learning from the Past Intrusion Attacks: Digital Evidence Collection to Make e-Commerce Systems More Secure
    (Conference ICL2009, 2009-09) Lokhande, P. S.
    Use of computers, data communication and data storage devices has become so ubiquitous that most of the crimes or civil disputes have involvement in some way. There will be a large demand for computer forensics in the coming days. Computer forensic has four phases: Collection, Presentation, Filtering and presentation. Computer Forensic: It is an art and science of applying computer science to aid the legal process. Computer involvement in crime such as fraud, child pornography and threatening emails. Another situation where computers commonly assist in a crime is intellectual property theft in the corporate environment. Computers were the targets of the crime such as during a Denial of Service (DoS) attack against an E-Commerce site. It is often less obvious than previous cases. Computer contains information that is incidental to the crime such as a database containing the payment and receipts list of gamblers, drug traffickers, and scammers. Pay and receipts (owe) are the documents made in spreadsheets to keep track of their customers and suppliers. In the same cases other innocent bystanders computers, WiFi networks may have hacked to send threatening mail for example mails sent by terrorist group before the bomb Blast in various cities of India.

    Academic audit is a methodical and scientific process of designing, implementing, monitoring and reviewing the quality in academic systems in higher education. The academic audit provides a strategic planning and its implementation for the teaching learning activity in the institute. In order to ensure quality and effective curriculum delivery, in teaching-learning, quality assurance system like Internal Academic Audit (IAA) system is very much essential. This paper aims to discuss the effective implementation of IAA in the technical campus situated in Panvel, Maharashtra. Academic Audit is done thrice during the term as Pre Term Audit- before the commencement of the term, Mid Term Audit- during the mid of the term and Post Term Audit- after the term end. Total thirty four numbers of input parameters are identified based on which academic audit is carried out. For every single parameter in the audit format, the course owner is evaluated for complete, partially complete and incomplete status of that parameter as per defined rubrics.The score of all the parameters is converted to a scale of 5 which would become the score of that course owner and would be used for appraising the concerned course owner.The reports of the Pre Term, Mid Term, and Post Term audit would be kept with the audit team and the necessary corrections would be conveyed to the respective course owners at the time of the audit. It was observed that after the introduction of the aforementioned process, the academic files of all the faculty members were found complete in all respects and quality of assignments, teaching learning and evaluation process was improved significantly.
