Informatic security

Lately we have seen some news about malware that attacks Linux-based systems, something not too frequent, but we must not be trusting and ensure that Linux is 100% invulnerable against these threats. Although our distros are much more secure than other systems, we must have common sense and protect our equipment against possible threats so as not to be surprised.

We have already talked in this blog about how use Squid o IPTABLES, to create a barrier in our network against possible threats. Because, having a firewall or firewall is a good practice to avoid these types of threats, but it is not the only or infallible, since threats can come from sources other than the network, such as an infected medium, etc. We also dedicate an article on how to install and use certain programs to detect rootkits and other malware....

But in this article, we will give you more options to be able to shield your computer with Linux and thus be more calm in the face of possible threats that threaten us. Although this does not mean 100% unconcern, you already know that total security does not exist, but we can improve it. Likewise, we have dedicated another article to give some guidelines to toughen up our distro that I also recommend that you read. And how do I consider that safety is a hot topic For the latest news of threats, although it should always be, here I put another grain of sand to be more sure:

  1. Have a set up firewall and other filters.
  2. Don't install packages from suspicious sources.
  3. Usa tools for threat detection on the table:
    1. Chkrootkit: to detect rootkits
    2. Rootkit Hunter: both chkrootkit like this one are focused on detecting rootkits and backdoors.
    3. ClamAV - a good antivirus that will detect and disable malware threats.
    4. LMD (Linux Malware Detect) - Another powerful tool for detecting malware.
  4. Other malware can be detected by other techniques monitoring the system, detecting anomalies with packages such as:
    1. HELP (Advanced Intrusion Detection Environment)
    2. Halloween
  5. In real time, you can also block some ads and threats on the net Through the use of safe browsers and some plugins or add-ons.

I hope I have helped you make your distro a little bit more secure, at least something else ...
