Blockchain-level Security Threats Sample Clauses

Blockchain-level Security Threats. Blockchain was developed as a technology for increasing trust and security. As an example, by binding subsequent transactions (“blocks”) by hash-values of their predecessors, blockchain delivers a strong method for assuring integrity of its data as a primary security goal. But, of course, data and information stored in such a distributed ledger are of high value and therefore can be an interesting target for attackers. In the following we have listed possible threats for the Blockchain proposed in the present document. Possible threats are those that attack a corresponding vulnerability that exists in the system under consideration. For calculating risk factors for a specific threat one needs the probability of an incident to take place and its possible impact. Both factors are hard to estimate and so we will focus on threats and not on risk values within the present document.

A particular problem is that the communication keys (cryptographic private keys) used in DER devices can have very different levels of security and protection, but such important information is not easily available to communication endpoints such as IEEE 2030.5 utility servers. To address this problem, SunSpec Alliance created the SunSpec Blockchain Work Group and hosted its first meeting on October 29, 2019. In the following meetings the work group discussed how a blockchain-based key registry for DER devices can provide an easily accessible repository for querying security-critical information about DER devices and their keys, while at the same time provide high availability and strong integrity protection for the stored information. The present document is the final report of this work group. The work group followed a typical standard creation process that starts with defining use cases and security threats before defining technological features and requirements. The main use case considered consists of manufacturers of hardware, key generators that create u...

  • Least Restrictive Environment The Board and the Association acknowledge that the policy of least restrictive environment is legally mandated and intended in the best educational interest of the student. Accordingly, the parties who would fit legal requirements which would involve the use of an Individual Educational Planning Team (IEPT) for placement in the regular classroom must be appropriate to the student’s unique needs as determined by an IEP on an individual basis. For the purpose of this section, such students shall be referred to as “mainstreamed students.” 1. Any member who has a reasonable basis to believe that a mainstreamed student assigned to that member has a current IEP report that is not meeting the student’s unique needs as required by law or whose behavior is physically or verbally abusive towards others and disruptive to the learning environment, should promptly notify the administration. 2. The following conditions shall apply to placement of mainstreamed students in general education classrooms: a. Any member who will be providing instructional or other services to a mainstreamed student in a regular education classroom setting shall be invited to participate in the IEPT which may initially place (or continue the placement of) the student in a regular education classroom. When invited to such an IEPT, the member will make a reasonable attempt to attend the IEPT and, when it is requested, will provide written input to the IEP (or the Multi-Disciplinary Evaluation Team Report to be presented to the IEPT). b. In instances where it is not possible to identify in advance of an IEPT general education teachers who ultimately will have mainstreamed student(s) assigned to their classroom(s), meetings will be convened with such general education teachers as soon as possible following the beginning of the school year to explain the conclusion of the IEPT and to provide for the teacher to have input. c. The district shall make every reasonable effort to provide the receiving teacher(s) with necessary support identified in the IEP, including paraprofessionals, materials and other related services. d. The administration shall provide, prior to such placement whenever possible, in-service training and awareness information to the teacher(s) regarding the instruction and behavioral management of such mainstreamed students in the regular education classroom setting, including but not limited to, the differing approaches, problems, and techniques to be utilized with varying physical, mental, emotional, and behavioral conditions as are likely to be faced in the given situation. Such training and information shall be provided at board expense and shall be mutually arranged with the teacher(s) to be involved. If such prior training and information are not possible, the training and/or information will be provided as early as can be arranged after placement has occurred.

  • Restricted Global Security to Regulation S Global Security If a holder of a beneficial interest in a Restricted Global Security deposited with or on behalf of DTC wishes at any time to exchange its interest in such Restricted Global Security for an interest in a Regulation S Global Security, or to transfer its interest in such Restricted Global Security to a Person who wishes to take delivery thereof in the form of an interest in a Regulation S Global Security, such holder, provided such holder is not a U.S. person, may, subject to the rules and procedures of DTC, exchange or cause the exchange of such interest for an equivalent beneficial interest in the Regulation S Global Security.
