  • Подробнее

Определение защиты электронной почты

Защита электронной почты — это меры, которые предпринимаются, чтобы исключить несанкционированный доступ к учетным записям и сообщениям электронной почты, а также их утрату или компрометацию. Для повышения безопасности в этой сфере компании могут настраивать необходимые политики и использовать инструменты для защиты от вредоносных программ, спама и фишинга. Киберпреступники организуют атаки на электронную почту, потому что она является удобной отправной точкой для доступа к другим учетным записям и устройствам. Кроме того, в работе с электронной почтой большое значение имеет человеческий фактор. Достаточно одного неосторожного перехода по ссылке, чтобы вызвать кризис всей корпоративной системы безопасности.

Почему важно защищать электронную почту

Электронная почта более двух десятилетий является основным средством коммуникации на рабочем месте. Ежедневно по всему миру отправляется и принимается более 333 миллиардов сообщений, а каждый сотрудник в среднем получает 120 писем в день. Это открывает большие возможности для киберпреступников. Они организуют атаки на электронную почту с целью кражи ценной корпоративной информации. Для этого применяются вредоносные программы, фишинг и множество других методов. Большинство кибератак (94 %) начинаются с электронного письма с вредоносным содержимым. По данным Центра приема жалоб на мошенничество в Интернете при ФБР, в 2020 году ущерб от киберпреступлений составил более 4,1 миллиарда долларов США (USD). При этом сильнее всего компании пострадали от взлома корпоративной почты. Такие атаки могут привести к серьезным последствиям: значительным финансовым и репутационным потерям, а также утрате важных данных.

Преимущества защиты электронной почты

Для компании любого размера важно уделять большое внимание безопасности электронной почты. Специальные решения защищают коммуникацию сотрудников и устраняют киберугрозы. Вот что это дает бизнесу:

  • Снижаются риски, связанные с ущербом для репутации и доходов компании. Атаки на электронную почту могут привести к огромным расходам, сбоям в работе и другим серьезным последствиям.
  • Повышается продуктивность. Надежные решения для защиты электронной почты позволяют компаниям сократить количество сбоев в работе и время простоя из-за кибератак. С такими инструментами службы безопасности могут оптимизировать реагирование на угрозы и действовать на опережение даже в случае изощренных атак.
  • Обеспечивается соблюдение законов о защите данных, например регламента GDPR. Это помогает избежать косвенного ущерба от кибератак, связанного со сбоями в работе компании, судебными издержками и штрафами регулирующих органов.

Рекомендации по защите электронной почты

Ландшафт угроз для электронной почты стремительно меняется. В ответ на это компании внедряют передовые методы защиты, чтобы сотрудники взаимодействовали в безопасной среде. Вот несколько рекомендаций:

  • Регулярно обучайте сотрудников, чтобы свести к минимуму риск ошибок, вызванных человеческим фактором. Персонал часто считают первой линией защиты компании, поэтому люди должны понимать важность защиты электронной почты.
  • Инвестируйте в обучение пользователей, чтобы они умели распознавать признаки фишинговых атак и другие индикаторы вредоносных действий.
  • Перейдите на решение для защиты электронной почты, которое обладает расширенным функционалом обеспечения безопасности.
  • Реализуйте многофакторную проверку подлинности (MFA), чтобы предотвратить риск компрометации учетных записей. Вход в систему с использованием более одного способа идентификации — это простой способ защитить корпоративные данные.
  • Проверьте, защищают ли ваши инструменты корпоративную почту от компрометации с применением спуфинга и олицетворения.
  • Переместите процессы и транзакции с высоким уровнем риска в системы с более строгой проверкой подлинности.

Типы угроз для электронной почты

Организации сталкиваются с целым рядом сложных атак: от захвата учетных записей и компрометации корпоративной почты до целевого фишинга и вишинга. Все эти угрозы можно разделить на несколько групп.

Кража данных
Кража данных — это несанкционированная передача данных за пределы организации (вручную или с помощью вредоносных программ). Утечка конфиденциальных данных может дорого обойтись компании. Шлюзы безопасности электронной почты помогают избежать отправки такой информации без авторизации.

Вредоносные программы
Основная цель вредоносных программ — нарушить работу компьютеров и компьютерных систем. Среди них распространены вирусы, черви, программы-шантажисты и программы-шпионы.

Спам
Спам — это нежелательные сообщения электронной почты, которые рассылаются массово и без согласия получателей. Компании используют такие письма в коммерческих целях. Мошенники же применяют спам, чтобы распространять вредоносные программы, обманом заставлять людей раскрывать конфиденциальную информацию или вымогать деньги.

Олицетворение
Олицетворение происходит, когда киберпреступники выдают себя за другого человека или организацию, чтобы заполучить деньги или данные посредством электронной почты. Компрометация корпоративной почта — это один из таких примеров. Мошенник выдает себя за сотрудника, чтобы похитить информацию у компании или ее клиентов и партнеров.

Фишинг
При фишинге злоумышленники выдают себя за другого человека или организацию, чтобы обманным путем заставить жертв раскрыть ценную информацию. Например, так они могут заполучить учетные данные для входа в систему и другие конфиденциальные сведения. Различают несколько типов таких атак: целевой фишинг, вишинг и уэйлинг.

Средства защиты электронной почты

Специальные средства для обеспечения безопасности помогают компаниям защитить учетные записи и сообщения электронной почты от киберугроз. Лучший способ организовать безопасную среду — создать и поддерживать политику использования почты. Ее нужно донести до сотрудников, чтобы они были в курсе основных рекомендаций. Вот несколько распространенных средств защиты электронной почты, которые доступны отдельным пользователям, учебным заведениям, сообществам и организациям:

  • Функции отключения сканируют входящую, исходящую и внутреннюю почту на наличие вредоносных ссылок и вложений.
  • Шифрование данных защищает сообщения почты от перехвата киберпреступниками.
  • Средства контроля сканируют вложенные или встроенные изображения и контент на наличие вредоносных программ и блокируют их загрузку.
  • Спам-фильтры отсеивают нежелательные сообщения электронной почты, например массовые рассылки.
  • Системы аутентификации оценивают надежность отправителей.

Безопасность электронной почты

Атаки на электронную почты становятся все более изощренными. Это требует внедрения надежных систем безопасности для защиты своих данных, репутации и доходов. В таких условиях компаниям стоит обратить внимание на решения, которые предлагают интегрированную защиту от угроз для приложений, устройств, электронной почты, удостоверений, данных и облачных рабочих нагрузок.

In summary, fixing Windows Security while connecting Microsoft Outlook requires a few simple steps. First, ensure that your antivirus software is up to date and not blocking the connection. Next, check your firewall settings to make sure Outlook is allowed through. If necessary, add an exception for Outlook in your firewall settings.

If you’re still having trouble, try repairing or reinstalling Microsoft Office. This can fix any issues with the Outlook application itself. Additionally, make sure your Windows operating system is updated to the latest version, as this can often resolve underlying compatibility issues.
