The management of risks in information systems includes five typical methods: avoiding, reducing, transferring, retaining or utilizing the risk at hand: Risk avoidance involves eliminating the risk's cause or the consequences related to the risk. The process involves an analysis of the chance of loss associated with a certain threat and should be followed up with the safeguarding of assets prone to certain vulnerabilities. Which of the following is the technique used to look for information in trash or around dustbin container? Risk retaining involves laying out a plan that will manage the risk. General description of the process of sending/receiving email: the first user sends a letter to the mail server of his provider; the postal provider sends a letter to the recipients providers server; the recipients provider server sends the letter to the recipient. Please let us know what you think of our products and services. Heres how and why. FEWM-2020-0037 (TUSUR). To compile a complete list of information flows, let us add a few more explanations to the description of the process: information on the users device is not generated by itself (although this situation is also possible), we will assume that in our case, the letter has only a text component and is typed by the user; Mail Transfer Agent (MTA) does not store messages, it only transfers them to the Mail Delivery Agent (MDA); situations are possible when MTA and MDA are one device, but in this example, we will distinguish them for greater clarity of the model; MDA (as with MTA) is a kind of hardware and software complex that consists of a message sending software and a data store; in our case, the interaction between the mobile mail client and the server software, which already interacts with the server storage, is carried out; we will assume that the interaction between the recipients mail client and MDA is carried out over the IMAP protocol. To clarify, lets get back again to the example of sending an email and lets apply the proposed model to one of the flows. 1. When deciding what threats and hazards to include in the THIRA, communities consider only those that challenge the communitys ability to deliver at least one core capability more than any other threat or hazard; the THIRA is not intended to include less challenging threats and hazards. As a result, the system is unable to fulfill legitimate requests. Let us turn again to the definition of the elementary information flow, which is described by the formula: It is obvious that an information transmission channel is not some abstract object, but a very real element of the system, which has some physical and/or virtual properties.
