    Ubuntu Security

    Ubuntu 12.04 LTS


    I need help about security, asking different appications but need this answers please bear with me.


    I have ClamTK, Firefox with Adblock Plus 2.2.3 and NoScript 2.6.5.8.
    I seen on the web not so good reports about this applications.

    I read that ClamTK is only need if working with windows in Ubuntu – Is this correct? (I don’t)
    Is the above with Ubuntu only, protects on a web or not?
    I found articles about AppArmor is this better than ClamTk, should I rather replace to
    AppArmor? (Using Ubuntu for banking).
    Found another application Host-based intrusion Detection Systems (HIDS) again ask if this is
    any good and should I use with my OS.
    Please advise me which is the best for peace of mind.
    Thank you

    Security is a process not a product.

    Start reading here https://wiki.ubuntu.com/BasicSecurity

    Apparmor and ClamTK are different products that do different things, it is covered in the link above.

    Learn early on that "Linux is not more secure" than other OS, as most people will tell you that it is(the followers that is). Also the "linux is more secure" statement is nonsensical and non comparable.

    There are steps you need to take with all OS to increase security, but nothing in a connected world is 100% secure.

    Have a good read.

    Peace

    Re: Ubuntu Security

    lumaja, can you give me some idea as to what types of threats concern you as 12.04LTS & Firefox with Adblock Plus 2.2.3 and NoScript 2.6.5.8 work together and are considered good bits of kit that work right out of the box?

    Your security should be in many layers starting with physical security and good strong passwords and pass phrases.

    Your should consider applying all security updates as they become available.

    When browsing or answering emails or banking via the net be aware of Social Engineering ploys that try to harvest your financial or personal data, these can be mitigated by Firefox with Adblock Plus and NoScript.

    It is only now that I would move on to other means of hardening your kit with some of the tools you have mentioned but as I lack knowledge in those departments I'll leave that advice to others.

    All the best with your research.

    Re: Ubuntu Security

    Its really not that Linux is more secure then Windows or MAC, its the fact that we aren't as targetted as much as the other user bases.

    Re: Ubuntu Security

    As a relative newcomer to ubuntu, the extra things that I do from a security standpoint are:

    Firefox and Chromium browser Apparmor profiles are set to to enforce.
    I use the bitdefender trafficlight browser plug-in to give bit of additional phishing/fraud protection to what is built into Firefox/Chromium.
    I use OpenDNS for much the same reason.
    UFW is set to default deny inbound and outbound, with essential outbound ports allowed only as advised in the security wiki (I don't know if this outbound restriction really adds much value though).
    I don't have java or flash installed (having read they are the main sources of cross-platform malware)
    I use a different user account for sensitive web transactions, and only for those transactions. In this account I only use FF. In my main user account for general stuff I use only Chromium.
    Given my long Windows background, I can't really feel fully relaxed without doing a bit of scanning (though those more knowledgeable will probably say it's pointless), so I do run an AV (and Chkrootkit).

    I don't claim that this is a particularly good or well-researched model, but it may give you some ideas to look into.

    Re: Ubuntu Security

    I have been trying to get BitDefender working for 2-3 days now and no matter what I try it will not scan.
    Yet the application launches and is up --

    You may not want to choose Bit Defender-
    If I get it working I'll be back:-

    ClamAV, F-Secyre and F-prot are other antivirus applications you could consider as well.
    Synaptic should have ClamAV unless of course you prefer the version you are already working with-

    Best regards

    Re: Ubuntu Security

    Found the :
    BitDefender-Antivirus-Scanner-7.6-4.linux-gcc4x.amd64.deb.run
    File online and ran it with chmod =x...(etc.)

    Turned on my system today and BitDefender is up and running and scanning.
    Took me 3 days of installing it and un-installing it and finally it is working!

    I Also had problems but went about install method diferently.
    Dont know outcome will be the same for everybody but heres how I did it.

    Code: wget http://download.bitdefender.com/repos/deb/bd.key.asc
    sudo apt-key add bd.key.asc


    [Add in Software Sources]
    deb http://download.bitdefender.com/repos/deb/ bitdefender non-free

    sudo apt-get update
    sudo apt-get install bitdefender-scanner-gui

    From Here:<https://sites.google.com/site/nikhildotnet/tutorials/linux/ubuntu-repository-ppa>

    It is a bit buggy on first startup though..
    Hope this helps..
