I have joined a number of websites over time and it seems harder to manage them. Would like advice on how to generate passwords and to store and keep track of them. I would like to hear of systems or programs that are good for this.
i need to do a statefull firewall actually i try the ESTABLISHED state but as we know that some people can play with the TCP header so i want to do a "connection track" state, they told me in mangle but i didn't find can someone paste for me a link about "connection track" or write for me rule for ex: to make connection track for port 80!
I am trying to find a best tool to track configuration files changes. I did find some information about osec and mactime, but, it seems, that they are not included in fedora/rpmfusion package databases. is there any tool that can be installed as a package?
To avoid having to input a password for the keyring each time I connect to the net via wireless, I enabled the 'Available to all users' option in Network Manager. Now, my question is this. Are the 'users' it refers to just those created on this machine? Would a drive-by be able to use my network without entering the password?
1. I understand you can protect your files or directories in your website by setting file/directory permissions. The meaning of r w x is clear to me, but I'm not sure how to proceed... Starting with the index.html file, if I wanted to make it so that anyone in the world can read it but can't modify it, do I set its permissions to rwxr-xr-x? If I set it to rwxr--r--, would that mean the file couldn't be served? I mean, what does the x setting do on a .html file, how can a .html file be executable?
2. If file permissions work on the lines of owner-group-others, in the context of a website, who is 'group'? As far as I can tell, there's only the owner, which is me, and others, which is the world accessing the site. Am I correct in thinking that by default, say when creating a website on a shared hosting server, there is no group unless I specifically set one up?
3. My ISP allows the DynDNS.org service, meaning that I could serve a website from my home. It's too early to go that route just yet, but for future reference, I would like to ask about the server software called Hiawatha. It is said to be secure, but having read some evaluations of it, it doesn't seem to offer anything that couldn't be accomplished with Apache or Cherokee, it's just that its security settings are simpler and easier to configure. Am I right about this? Or does Hiawatha truly offer something that the other major server packages don't?
this is the allert i got:Code:Summary:Your system may be seriously compromised! /usr/sbin/NetworkManager tried to loada kernel module.Detailed Description:SELinux has prevented NetworkManager from loading a kernel module. All confinedprograms that need to load kernel modules should have already had policy writtenfor them. If a compromised application tries to modify the kernel this AVC willbe generated. This is a serious issue.Your system may very well be compromised.Allowing Access:Contact your security administrator and report this issue.Additional Information:
i updated both browsers i have and lost my secure log-in pages (no padlocks showing ) concerning different Web mail accounts.Just before i did these updates i checked an unrelated thing on-line regarding my sound card of which i kept a copy of and got this message below :

I'm just curious as to what security measure's I should be taking to make my box a little less vulnerable? I'm still experimenting/playing with Linux, use the net, IM, download this and that and was wondering how secure fedora 10 was out of the box?
During a recent install I made the leap to encryption,but /boot must remain unencrypted.Is there really any legitimate security risk to having an unencrypted /boot partition? I mean basically someone can just see what kernel you're running which they could see during boot anyways right? Oh I and keep all my financial documents in /boot/finances/ (haha ok not really, but I am serious about the first part).
Is there a way to delete files on the commandline that uses the KDE-Wastebin?It appears that I never ever need the KDE4 Wastebin for files that I deleted through Konqueror or Dolphin. It is only when I delete files on the konsole with rm that I wish I could undelete them. It always happens like that, mostly by being in the wrong directory or using a wildcard when I should not have. (I don't have any erroneous deleted file right now, and I do have plenty of backups, but I just wonder whether there is something better than rm to use generally on the commandline.)
Conky can be used to display a variety of information on the users desktop. I wanted to use Conky instead to display the current status of security as reported by:
SANS Internet Storm Center IBM Internet Security Systems Symantec Threatcon McAfee Threat Center
I therefore created 4 small scripts which download the current status from these sites, and set the colour of those status's depending on the current value.The conky configuration allows for a semi-transparent background - though this is optional.Attached is an example image showing the 4 different colours.Also attached is an archive with the 4.sh files, .conkyrc and draw_bg.lua (from here http:[url].....
I already posted a topic similar to this concerning the Desktop OS version, but this deals with the Netbook because unlike the Desktop, the Netbook is less cooperative. Allow me to elaborate: Today (or rather yesterday since it's not after midnight where I am), I changed my password because I was hopelessly confounded about how to get my Wireless Network card up and running after it had been installed and I was allowing my dad to use it. This issue has since been resolved, however...
When I chose my password during the original installation, there was no mention of it being "too simple." This is where the Desktop OS and the Netbook OS differ. The desktop will let me change it in the terminal without any errors. The Netbook will not. When I've attempted to revert it back to the original, it will not let me do so in the User Profile or in the Terminal. The Passwords and Encryption Keys application also does not appear to help.
So now even after I've changed it to a different "complicated" password I am still prompted to insert two different passwords since I changed my user password but I am unable to change the password I input during the installation. A bit screwy methinks. This is extremely important. I'd like to know how to change the original installation password.
If I can't change the main password on my laptop then this is a serious potential security breach just waiting to happen (especially since it's on a laptop and I will be hauling it around with me) and I will most likely install a different OS if this isn't resolved --- It would be very unfortunate since I spent the whole day fixing it and I really enjoy the interface. Luckily I can live with this on my Desktop since I'm not going to be hauling it around with me everywhere when the school year starts.
As it stands I have a small home network operating behind my modem/router. Some of the ports on this are forwarded to my PS3 for gaming but I was looking at forward some for my file server.
At the moment I've forwarded port xxx22 to port 22 on my server for SSH for instance. ANd similarly 21 for FTP (although it doesnt seem to want to connect for any more than a few seconds using that). What I was thinking of doing was placing a small website for a handful of ppl to use on the server too and port forward again - xxx80 to 80. It works just fine but I'm a little concerned on the security front.
As I've moved the port to something different from the outside world I'm presuming I will have already cut the potential for malicious folks to wander in but is there anything else I should be doing? At the moment there's no firewall operating on the server, usually as its hidden behind the modem/router. But if I open this thign up more permanently what should I be doing? I've read a few articles on it but I'm always left with the overwhelming thought of "Thats if theres no firewall in my router" as they just seem to do the same.
I'm concerned about security of having a LAMP server on my laptop as having any server makes the system less secure. However, if I were to create a new partition and install a lamp server on that and only use it when offline, would the security of my main partition be affected at all?
The default Firewall ufw is not enabled by default at the time of installation and it has to be enabled by the user.Isn't this a security risk or is the user whether ufw is enabled or not secured from external threats?I am not much knowledgeable about network security But I am trying to understand the Ubuntu mentality behind this default setting.
I've recently been running a game server from my desktop, as well as a web page to accompany it.I use the ports 80/8123(HTTP)/5900(VNC)/50500(GAME)/5839(ADMINISTRATION).What's the best solution to protect my server from security threats? On a side note, I plan on adding a MySQL server later, but I want to keep it local only.
I've got a samba share on a linux server, connecting to it with a windows 2k3 server via tools > map network drive. The goal is to be able to use windows to change the security of the samba share. The good news is it works! The bad news is it's not QUITE perfect:
The share is called /company. I started with the following to give everyone access to everything, set the owner of the share to administrator (my domain admin on the Windows domain), and set the group owner to domain users (group that everyone on the domain is part of):
I then mapped the drive as a regular user, and of course, can access/modify/delete/rename/create anything I want. Then I picked a folder to lock down. Let's call it /company/myFolder. I did this on the Windows server by mapping the drive as administrator (the owner), right click > properties > security tab > advanced > highlight "domain users" and "everyone" and click edit > clear all (i.e. remove all access). Go back to Linux and
The only issue that remains is that I am able to rename/delete "myFolder" as a regular user. I thought this was coming from the "acl map full control = true" parameter in smb.conf, but I changed it to false and verified the change and it still happens. If I remove group and world write access to /company, I am no longer allowed to rename/delete myFolder, but then I can't create a new folder. If I add group write access back in I can create files but can also rename/delete folders within /company that have --- specified for group access. Any ideas what I need to tweak to make this right?
Currently I'm looking into implementing mod_security on all our apache servers. The installation on CentOS 5.5 comes directly with the "Core Rule Set" by the mod_security devs (curiously Debian and Ubuntu do not carry these) They also offer the Enhanced Rule Set for mod_security in a commercial package [URL] The main point there in their info link is the first point
Tracking Credit Card Usage as required by the Payment Card Industry Data Security Standard However acc. to this wiki article ( http://en.wikipedia.org/wiki/Payment...urity_Standard ) that specific requirement isn't stated anywhere, as well as my colleague who's working on the PCI-DSS compliance for our code/servers/etc. mentioned that he hasn't heard of this specific requirement either. So my question would be if anyone has any experience with their ERS package and if it's needed for the PCI-DSS compliance compared to the requirements given in bullet points @ wiki article.
I have a CentOS 5 server in which I use Virtual Hosting and each domain has its own user/pass for login to upload files. The path is /var/www/vhosts/domain name]/httpdocs/What im attempting is setting up the creation of the [domain name] folder from an administration backend under PHP, which I am developing. What Im worried about is if I allow PHP to run command line commands such as mkdir, then what is stopping anyone from doing the same from their php files on my server??? What is the best way to properly setup my server to allow automated creation of the domain structure within my folder system
I am surprised (from the searches I carried out on the net) that no one seems to have considered this danger so far as I can see...I'm a little concerned about the implications on security for algorithms that opaquely shift data blocks around on disks to even-out surface wear rates.In the good old days, if I wanted to wipe a file that documented my struggle to give up frosted strawberry donuts (for example) I knew where that file started on the disk and how long it was and could thus instruct the OS to wipe it with complete confidence.
Nowadays, however, with increasingly sophisticated use being made of W-L techniques and fancy, journaling file systems that separate meta-data from file content and whatnot and so forth, how can I still be sure that when I try to overwrite a personal and private file, that i AM actually doing precisely THAT, and not just nuking some virtual image of the thing which in reality remains preserved elsewhere on the disk?
I have an environment with multiple projects that have a variety of government and commercial sponsors. We have been satisfied to this point with a netapp serving nfs/cifs and keeping a tight reign on nfs exports.Some of these projects have started asking us to provide access restricted sub-folders of the project space based on different groups that contain a user subset of the primary group.
We have a linux machine that serves as a version control front end to the netapp, mounting the project spaces via nfs. People are now mounting their project space via sshfs to this "front end" and sharing the root password of this sshfs client with everyone in their project, in turn creating a security hole to access the so called restricted sub-folders. I know all the obligatory responses referring to irresponsible user behavior but would like to see how others have addressed something like this where user behavior seems out of control.
If I leave the computer running for a few minutes without doing anything on it, this screen appears demanding that I enter my password, otherwise I can't get back to Fedora. I understand the necessity for this security feature in a work environment, but I'm just a home user and this security screen is just a nagging problem I don't know how to get rid of.
