IPtables для обеспечения безопасности информационных сетей на базе Linux
Статья научная
В статье рассмотрены основные компоненты информационной безопасности: конфиденциальность, целостность и доступность. Пароли, шифрование, аутентификация и защита от проникновения - это методы, предназначенные для обеспечения конфиденциальности. Целостность означает поддержание данных в исходном состоянии и предотвращение их изменения: случайного или злонамеренного. Под обеспечением доступности информации понимают соответствие сетевых и вычислительных ресурсов ожидаемому объему доступа к данным и реализацию политики резервного копирования для целей аварийного восстановления. Для обеспечения безопасности информационных сетей на базе RedOS наилучшим образом показала себя утилита iptables, используемая для настройки брандмауэра ядра Linux. Несмотря на то, что на первый взгляд реализация IP-маршрутизации в Linux может выглядеть довольно сложной, на практике наиболее распространенные варианты использования (NAT и/или базовый брандмауэр Интернета) значительно проще реализуются. Iptables - это пользовательская утилита, позволяющая работать цепочками/правилами. В статье подробно рассмотрены принципы работы iptables, приведено подробное описание таблиц nat, mangle, filter, raw и цепочек. Таблица nat используется для трансляции сетевых адресов, mangle применяется для искажения пакетов, filter дает возможность выполнять фильтрацию пакетов, raw и ее цепочки используются перед любыми другими таблицами в netfilter. Цепочка input применяется для обработки входящих пакетов и подключений, forward - для проходящих пакетов, output - для исходящих пакетов. Показано, что для обеспечения безопасности функционирования компьютерных классов и всей сетевой инфраструктуры в целом, достаточно только двух таблиц: filter и nat. Другие таблицы предназначены для сложных конфигураций, включающих несколько маршрутизаторов и решений по маршрутизации. Приведены результаты использования iptables на основе опыта администрирования информационных сетей на базе RedOS в федеральном государственном бюджетном образовательном учреждении высшего образования «ПГУТИ».

Identity in Kyrgyz women's poetry
Статья научная
This paper reflects our experience teaching contemporary American women’s poetry and translating Kyrgyz women’s poetry into English. This paper mainly intends to explore essential questions and issues that lie at the very heart of what it means to be a woman in today’s world - questions such as “What is a woman?”, “What does it mean to write as a woman and to read as a woman?”, “How is the concept of being female described in Kyrgyz poetry?”, “What kinds of challenges, women’s strengths and weaknesses do poets see in themselves?”, “What do women value or believe in?”, “How can poets express themselves through poetry?”. In the attempt to address these questions, we investigate some of the ways that Kyrgyz and American poets handle nature of female poets, women’s experiences in contemporary society, and the effects of prejudices and stereotypes described in women’s poetry. Examples are taken from the works of contemporary American women poets (Maya Angelou and Amy Smith) and from the collection of translations of Kyrgyz women’s poetry into English (“ Girls you... / Kyrgyz Women Poetry ”, translator Kalieva K., editors Simone P. Bures and Daniel Kittle).

Cultivation of soil on the slopes of mountainous areas leads to a decrease in organic matter and nutrients in the soil and severe soil erosion. Grazing is one of the main reasons for the degradation of pastures and natural landscape, which increases the sensitivity of the soil to erosion. Soil erosion, in turn, pollutes water by increasing its turbidity and sometimes causes atrophy due to leakage of phosphorus and nitrogen. An average of 30.6 quintals of green mass or 7.8 quintals of dry grass per hectare was produced in the variant of grass seed sowing (without fertilizer), compared to the control variant, in the variant of grass seed sowing + N60P60K40 this indicator averaged 39.9 centners/ha of green mass. or more than 15.0%, resulting in the production of 10.0 quintals of dry or 14.7% more dry grass. Experimental field studies to improve pastures have shown that the fodder produced in each of the tested variants; green mass and dry grass supply and their nutritional value were higher than control.

Important Aspects in Assessing the Personal Qualities of Management Personnel
Статья научная
Each leader is a unique individual with unique management skills. In most cases, there is a view that the organization is a projection of the personality of the leader. Human nature is inherently complex. It is therefore not always appropriate to associate the leadership qualities of a leader with a style of leadership in exactly the same authoritarian, democratic or liberal form. In many cases, however, there are leaders in this balance. A leader - as a manager in the organization — must have the ability, talent and, of course, the psychological will to be able to react differently to different situations in the management process. Therefore, when appointing staff to management positions or analyzing the activities of management staff, there is a need to assess their personal qualities. Through such an assessment, it is possible to make decisions about the formation of the moral image of the leader in management, as well as the development of his personal qualities. Because for a person to have good professional qualities, his personal qualities must be good. The article argues that the role of the leader in the evaluation of management performance is important in the study, analysis and, if necessary, the development of conclusions. Several respondents participated in the analyses studied. The answers to the questions asked in the specially designed questionnaire were shaped by the questionnaires in them.
