Как сделать проверку короткой ссылки на безопасность

Использование служб сокращений ссылок позволяет превратить их в красивый вид и сделать более запоминающимися для пользователя. Изначально URL имеет длинный адрес, что не позволяет его запомнить и легко ввести. Однако сокращение имеет и отрицательную сторону: оно не дает возможности понять истинное назначение адреса. Поэтому важно использовать средства для проверки URL.

  1. Ярким примером необходимости проверки ссылок является сервис Twitter. В нем реализована служба, сокращающая каждую ссылку до 23 символов. Она нужна не только для сокращения, но и учета кликов. Кроме того, служба проверяет ссылку на наличие вредоносного содержимого. Проверка происходит через базу опасных сайтов. Twitter автоматически оповещает пользователя о потенциальной угрозе при переходе по адресу. Рассмотрим, какие существуют сервисы для определения безопасности ссылок.
  2. Сервис Bitly.com позволяет проверить любую ссылку, добавив в конце «+». Вы сразу увидите, куда приведет вас URL-адрес. Сервис проверяет страницу на наличие вредоносного кода, используя независимые источники.
  3. С помощью TinyURL можно выполнить предварительный просмотр страницы. Достаточно добавить к ее сокращенному варианту «preview» перед началом адреса. Сервис в подробностях покажет, куда именно ведет вас ссылка. Есть специальный сайт CheckShortURL.

    Скриншот к CheckShortURL.

    Для его использования нужно добавить ссылку в соответствующее поле и нажать кнопку Expand. В результате вы получаете укороченный вариант адреса. Также копания Norton предоставляет специальный сервис Safe Web. На сайте можно ввести ссылку и получить рейтинг от Центра безопасности Norton.

  4. Полезным окажется и Unshorten.It. В строке поиска нужно ввести сокращенный URL, нажать кнопку с названием сайта и получить полный адрес. Одновременно сайт проверяет страницу через сервис Web of Trust.
  5. Таким образом, проверка URL-адреса является доступной каждому пользователю. В случае сомнения по поводу ссылки воспользуйтесь одним из предложенных вариантов. Помните, что при переходе на подозрительные страницы вы подвергаете опасности свой компьютер и операционную систему, допуская возможность встраивания нежелательных плагинов в браузер и даже загрузку потенциально опасного программного обеспечения.

    I have been surfing on-line more than three hours today, but I never found any attention-grabbing article like yours.
    It is lovely worth sufficient for me. In my opinion, if all

    did, the net will probably be a lot more useful than ever before.

    more popular because you surely have the gift.

    Does running a well-established website such as
    yours take a lot of work? I’m completely new to blogging however I do
    write in my journal on a daily basis. I’d like to start
    a blog so I will be able to share my experience and thoughts online.
    Please let me know if you have any kind of suggestions or tips for brand new aspiring bloggers.

    Yesterday, while I was at work, my sister stole my iPad
    and tested to see if it can survive a thirty foot drop, just so she can be
    a youtube sensation. My iPad is now broken and she has 83 views.
