Carlos Silva<p>Bastaria lembrar o número de vezes em que um simples sudo apt install ou sudo nano evitou que se digitasse a senha de root diretamente. Porém, a criação do comando sudo não foi apenas uma melhoria funcional: ela representa uma mudança paradigmática na forma como o Linux e os sistemas Unix lidam com permissões e controle de usuários. </p><p><a href="https://mastodon.social/tags/linux" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>linux</span></a> <a href="https://mastodon.social/tags/sudo" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>sudo</span></a> <a href="https://mastodon.social/tags/hardening" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>hardening</span></a> <a href="https://mastodon.social/tags/security" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>security</span></a> </p><p><a href="https://sempreupdate.com.br/criacao-do-comando-sudo-historia/" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">sempreupdate.com.br/criacao-do</span><span class="invisible">-comando-sudo-historia/</span></a></p>

MITIM Blog<p>New post 🎉<br>In this long blog I try to sum-up some features which you should disable before running MikroTik in any environment. First of all is an `backup` interface, so in case you lock yourself up, you will always have a way to login. Other points include creating custom user, disabling unused services in various places throughout the RouterOS and if you don't need IPv6 then disable it too just in case 😉.<br><a href="https://www.mitim.net/2025/06/hardening-mikrotik-and-network-infrastructure?g=5" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">mitim.net/2025/06/hardening-mi</span><span class="invisible">krotik-and-network-infrastructure?g=5</span></a><br><a href="https://mastodon.social/tags/Hardening" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Hardening</span></a> <a href="https://mastodon.social/tags/MikroTik" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>MikroTik</span></a> <a href="https://mastodon.social/tags/Networking" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Networking</span></a></p>
