DEMIDS: a misuse detection system for database systems

Abstract: Despite the necessity of protecting information stored in database systems (DBS), existing security models are insufficient to prevent misuse, especially insider abuse by legitimate users. Further, concepts for misuse detection in DBS have not been adequately addressed by existing research in misuse detection. Even though there are available means to guard the information stored in a database system against misuse, they are seldom used by security officers because security policies of the organization are either imprecise or not known at all.

Temporary guard rail system

The guard includes a clamp ring depending from a guard hood. The clamp ring's inner circumferential portion has at least a partially-knurled surface, whereby when securely tightened around the semi-elastic lower bearing housing, the at least partially-knurled surface of the clamp ring inner circumferential portion compresses into the semi-elastic lower bearing housing to securely mount the guard to the tool.

Elites in Post-communist Russia: A Changing of the Guard?

Abstract: SINCE RUSSIA’S EMERGENCE AS AN INDEPENDENT STATE considerable disagreement has arisen among both Western and Russian scholars over whether a transformation in the political elite has occurred. Representing the prevailing consensus, a number of authors contend that the Soviet political elite has largely reproduced itself in the new Russian state. On the other hand, several studies reach the opposite conclusion—that there has been a signiŽ cant amount of elite circulation in Russia since the demise of the Soviet Union. Which of these views is correct? Has there been a changing of the guard in the political stratum of post-communist Russia? This article addresses this question, focusing exclusively on the continuity of a speciŽ c variety of leaders. It analyses the extent of turnover among political elites (as opposed to, say, economic or cultural elites) at both the national and regional levels in Russia. This issue is by no means trivial for the future of democratic consolidation in Russia. As classical elite theorist Gaetano Mosca argued, large-scale societal change produces a need for new capacities in managing the state. This leads to elite turnover; indeed, unless the ruling class adapts to and absorbs representatives of the new and emerging social forces into its ranks, it will decline in power. By extension then, we can see that a ‘revolution’ will be incomplete to the extent that representatives of old interests continue to exert disproportionate in uence in the face of rapid social change. And in fact, scholars of regime transition point to cases where elite continuity has stalled political reform. In Brazil traditional political elites were invited to join the democratic project by opponents of the ruling military government. By exploiting their status in an effort to safeguard their control over political patronage, these traditional elites constituted an obstacle to the extension of democracy once the transition had taken place. After democracy was restored in Chile in 1990 the continuing presence of General Pinochet as commander of the army impeded President Aylwin’s efforts to restore civilian control over the military and enact constitutional and legislative reforms. The costs of including former elites in the democratic transition may even be higher in the East than in the South. Since the task in the formerly communist region is one of dismantling an entrenched system of state socialism, the presence of former communists may derail the wholesale reconstruction of state-society relations. In fact, Valerie Bunce argues that those post-communist countries which initially excluded their former leaders from political power have shown the most progress in economic and political reform. Likewise, Steven Fish demonstrates that successful economic

Apparatus and method for synchronization in a multiple-carrier communication system by observing energy within a guard band

Abstract: A method, apparatus and system detects a loss of synchronization between a transmitter and a receiver in a multiple-carrier communication system such as an OFDM system. A guard band synchronization detector provides a synchronization indicator based on the energy detected within a guard band where a pilot tone is transmitted adjacent to the guard band. A timing error results in energy leakage into one or more guard bands. In one embodiment, a plurality of synchronization indicators are observed to determine whether a loss of synchronization between a transmitter and a receiver in the wireless system has occurred.

Honesty in negotiation

Abstract: It is often suggested that deceptive behaviour in negotiation is ethical. A number of academic writers have put that view, and several have even suggested that a contrary approach is naAve. Writers argue either that deceptive behaviour is generally expected or else that such behaviour is necessary to enable us to guard ourselves against exploitation. But in fact participants in the negotiating process differ in what they expect, and we can be careful without being deceptive. That is how we ought to proceed, if we want to treat others as responsible decision-makers. Our obligations in business negotiation are the same as elsewhere. Business is not a distinct game with defined rules, like poker. Neither ‘business’ nor ‘negotiation’ are by their nature set apart from other situations. The behaviour which is appropriate in negotiation depends on the circumstances. As in other situations, we have an obligation to pay attention to others to ascertain their actual expectations and intentions, and then act accordingly.

Secure Concurrency Control in Firm Real-Time Database Systems

Abstract: Many real-time database applications arise in electronic financial services, safety-critical installations and military systems where enforcing security is crucial to the success of the enterprise. For real-time database systems supporting applications with firm deadlines, we investigate here the performance implications, in terms of killed transactions, of guaranteeing multilevel secrecy. In particular, we focus on the concurrency control (CC) aspects of this issue. Our main contributions are the following: First, we identify which among the previously proposed real-time CC protocols are capable of providing covert-channel-free security. Second, using a detailed simulation model, we profile the real-time performance of a representative set of these secure CC protocols for a variety of security-classified workloads and system configurations. Our experiments show that a prioritized optimistic CC protocol, OPT-WAIT, provides the best overall performance. Third, we propose and evaluate a novel “dual-CC” approach that allows the real-time database system to simultaneously use different CC mechanisms for guaranteeing security and for improving real-time performance. By appropriately choosing these different mechanisms, concurrency control protocols that provide even better performance than OPT-WAIT are designed. Finally, we propose and evaluate GUARD, an adaptive admission-control policy designed to provide fairness with respect to the distribution of killed transactions across security levels. Our experiments show that GUARD efficiently provides close to ideal fairness for real-time applications that can tolerate covert channel bandwidths of upto one bit per second.
