I am looking for a basic guide to Linux security. I am assessing a multi-server farm and have very limited experience with Linux. Where can I get a list of basic things I should be looking at from a security standpoint, i.e. ports, vulnerabilities, users, etc? Looking for a checklist I can run through. We are running CentOS Linux 5.0.

View 6 Replies View RelatedI'm working through some problems in a beginners programming book. The author mentions a formula for calculating the number of ways of picking out n things from a collection of m of them:
Code:
/ m m!
| | = -----------
n / n! (m-n)!
But he does not give a name for the formula. Does anyone happen to know what it is called? I need to do some related research.
Most of us know the basic security practices on Windows:
Use a limited account
Set a password
Disable unused services
Uninstall bloatware
Antivirus / Antimalware
etc.
I haven't ran linux as my main desktop computer before, so I don't know how to properly secure it. I have heard linux is supposed to be more secure than Windows, but I know that the default settings of anything are rarely secure. What are some things I should do as a new Linux user to secure my desktop system from attack?

when i got my starling netbook 6 months ago it worked perfectly. due to upgrades since then i now have problems with printing, sound and videos. there are probably solutions to all of these things if i spent hours here on the forum asking questions, and trying different solutions, but it seems like a lot of work.
upgrade manager calls these things "important security upgrades". are they really important to security? would my computer be dangerously vulnerable to attack if i never did an upgrade?

View 2 Replies View Relatedis there a way to display a list of all the files changed during current session?
View 4 Replies View RelatedI am looking for a utility that would do the following:1. Be run manually on a list of files whose sizes should not change, to get a control file containing the sizes of each file.2. Subsequent manual runs would report any changes in size of any of the files in the list, and allow option to accept the new sizes.3. Be run as a cron job to check for changes in the file sizes and send an email alert if a change has occurred since the last time it was run.The purpose is to detect possible hacks of key files on a website. It would not include files expected to change, but just those that should not change. It would be run manually a few times to get the control list one wants to monitor.

All I want is for my bootloader to show "Ubuntu" & "Windows XP" which are the only 2 OS's I have installed (dual booting). At the moment it shows Windows XP, Ubuntu, Ubuntu recovery mode & like 2 more.. which are also Ubuntu & recovery mode. I've never selected the other Ubuntu ones, only the first one. So, how can I remove the ones I don't want to show on the list.

Ive noticed this in 2 places specifically.The first is when I try to open the only "tarball" program Ive ever tried to install, Celtx. I unpacked the program into my bin folder, and when clicking (or double clicking) on either the executable file or the shell script nothing happens. If I double click on shell script, and then on the executable, I get an error saying "celtx is already running but not responding. To open a new window you must first close the existing celtx process, or restart your computer".
The second time is when I get a notice on my screen about new security updates available.I click on it, and it opens up the "software update" window with the updates it wants to nstall already checked. I click "install updates" and nothing happens. If I click the help button, it gives me an error "failed to execute child process "gnome-help"". Im guessing this one is because Im not using gnome, but XFCE. If I open up online update using yast, I can update from there and install these files fine.So basically the second problem is not that big of a deal, since Im able to install the files from a different area. Its just annoying and I dont know if it means there is a deeper bug in my system. The first problem makes me unable to run a program I really wan to run, so thats the one I really need the most help with.
I updated through the update manager the other day and after I shut my computer down and turned it back on the next day, all my icons on my desktop disappeared and I can't access my files or my applications. It gives me this error when trying to access my files in my desktop.
Could not open location 'file:///home/anubis/Desktop'
No application is registered as handling this file.
I posted a new thread about this the other day and somehow the thread disappeared too. what do I need to do?
