Now, before you say it, the real flaw is the compiler. But, that too comes from the usual holier-than-thou culprits. They can't fix it unless they fix the compiler.
And of course, there is the usual see no evil-hear no evil head in the sand approach to defending the honour of their little pet.
I run a web hosting company and one of my servers is a LAMP server running CentOs 5. A user of mine has a Joomla installation running to manage his website and he has run into the following problem that I am puzzled by.
When Joomla adds a component or module to itself, or when a user uses the Joomla upload functionality, Joomla will add the new files under the user name "apache". This makes sense as it is the apache service running PHP that is actually creating the files.
However, when he FTP's into the account to modify these files, he doesn't have the appropriate permissions to do so as he doesn't have a root level login, just permissions on his home directory which is the site. Any help would be much appreciated.
Also, does anyone know how to change the owner/group of a directory and all of its sub directories in Linux without changing the actual permissions? I.e. some of the files in the folder have different permissions (0644 as apposed to 0755) than its parent but if I do a top down user/group change on the folder it will change everything in that folder to 0755.
About next week, I'll put a Linux box on the web.
Could anyone suggest what kind of security measures I could implement?
Iptables:
- Protect against DDos?
- Protect against certain worms?
- Protect against flooding?
Services:
- Protect against constant dictionary attacks based on ports?
Pretty much any experience you could put down in this thread would be invaluable.
Also mod, if this shouldnt be here. Feel free to move, Im not sure where it should go!
What is the best security (antivirus/firewall) for a linux web server?
View 4 Replies View Relatedi have managed server. just i want sure if it is secured.
i want company to test my server, Security Scanner.
and give me report about my bugs.
I have Parallels Plesk 12.0.18 with CentOS 6.5 (Final)
WAF is On, with Atomic Basic ModSecurity rule set.
I was wondering if my sites were protected and I went to the Atomic wiki.
When I run a test from a non-whitelisted system following these instructions (STEP 10) [URL].... I always receive 404 error with all of my sites.
I also tested with:
[URL]...
Results: The sites load normally. (the call not even appears in the logs)
I've unistalled and reinstalled mod_security several times with the same results.
Is there any "official" way to check if WAF is protecting Plesk 12?
I asked same question in Atomic forum and they said:
you'd need to ask parallels about this, we made the ruleset available to them, but they implemented it using their own design. They might not be using 403 error codes like we do.
Your Favorite Security Tools For Your Linux Web Servers
Just wanted to know what all you guys favorite tools are for your Linux Web Server Setups
Plesk 12 on Centos 6.5
I added the following to my /etc/logrotate.conf
/var/log/modsec_audit.log {
missingok
daily
rotate 4
compress
}
I'm not exactly sure if the above is the correct syntax, but the result was that two days later my current modsec_audit.log was Gzipped and a new modsec_audit.log was created.
The problem is that nothing was logged to this new file.
From the Plesk 12 control panel I turned off mod security and then turned it back on again and hey presto, the new logfile started to log events.
This leaves the problem of why nothing was recorded when the file was created.
What are new methods to High secure a linux server ? (For webhosting company)
Please write something you know for Linux Security Methods (New version of OS).
After upgrading to Plesk 12 the FTP connection has become very slow. Mode Security, Fail2Ban and Plesk Firewall have been enabled, the security is set to force sFTP and maximum security and in /etc/proftpd.d/ a conf file has been added to set the passive ports that have been opened in the Plesk Firewall (60000 to 62000)
Turning off the Mod Security does not solve the slow connection.
What can we do to detect the cause of the problem?
I have tried this on Plesk 11.5 and Plesk 12.0.10 Preview running on Ubuntu 12.04.4 LTS...

How can I do to send email without the security warning?
I want the clients sending mails no longer have a security warning.
I tried with SSL port 465
I tried with port 587 TLS> Mail settings for the entire server> Enable Send Message
I thought this problem was fixed in Plesk 11.5 but I'm still getting the following backup warnings in Plesk 12..."For security reason backup is performed on behalf of subscription system user...."
My phpbb forum creates cache files which have apache ownership and Plesk backup manager gives warnings that it cannot backup the files due to ownership errors.
I have searched for days for a solution without success. If I change the permissions to owner instead of apache the forums don't function correctly.
Is this a Plesk bug that is still evident in Plesk 12?
I have regarding hosting/designing my application. Users of my website upload highly sensitive files to the server. I'll use SSL but will that be enough since the files are not encrypted on the server. I tried to encrypt the files but that is adding a huge overhead.
My first question is - is it a good idea to store the files on the server rather than a database? My other question is regarding hosting; I'm thinking of building my own server and host it in a colo. Is colo more secure than dedicated hosting? Currently i'm still in the process of developing my App and my environment is Windows Server 2008/SQL Server 2005.
Is there any problems with having duplicate rules in different files as I have downloaded some rules and am going to make them all into one file to give me the best protection, but this is going to take time and I really need some sort of protection now

I am on a shared server account with Lunar Pages basic hosting plan.
The only script file I have up running is db Masters FormM@iler. It runs on Cpanel. I deleted whatever other scripts I could find on my server. The site is just basic html pages with jpgs and a gif.
Is there much else I really need to do to secure the server or is that more in Lunar Pages' hands?
If there is still more I can do to secure the server, and is it a small amount that's easy to do or would it be wise to just hire someone else to put in a few hours making sure everything is truly set up securely?

View 8 Replies View RelatedI'm inheriting a website that is currently a mess. It was designed in Joomla, but everything about the site by the original designer, is completely a mess. Files weren't placed in their proper directory hiearchy, the site has been hacked into a few times...basically a big headache.
I'm willing to learn and my first goal is the redesign the site. Currently, I'm looking at choosing a CMS or just rebuilding it in Joomla. The problem is that the site is a big part of the business, so any down time is not good.
I have some questions I hope you experienced folks can help me with...
Does CMS choice have any bearing on whether or not its a security vulnerability? If so, which one's are "less a target" of getting hit?
I just want to design the site from scratch and make it secure as possible from suggestions on various forums. I don't want to be a security admin, but is that what I'll end up having to do to run a site like this?
What are my options between "doing it myself" vs "hiring a third party"?
The company is right now in a tween stage. Fast growth but not enough to hire a security guy, based on my talks with the CEO. I disagree with this, but what can I do in the meantime to plug the site holes?
I'm almost wanting to go commercial so I don't have all the headaches, but the company wants to save money. What can be done in those situations?
Before I go out and spend money on books, what do you recommend I buy to start getting my feet wet in what may become a future in IT security?
This is from someone who's just inherited a dedicated server with a swiss cheese website. What is the first order of business for someone who is in the dark and will not get much support in regards to spending more money?
how do I secure my site "on my own"?
I noticed that my vps had utilized 250 gig of traffic in one day [i average 5 gig per MONTH] with cpu usage of close 100%; my hosting company pinpointed one php file which had allowed an outside varibale to be placed in "include" function so that the outside php code was being run;
Is there any program/scripts that can immediately email me if cpu usage stays high
the nic card is being utilized too much memory usage exceed certain levles this way, i would know i have been hijacked in time and try to find the culprit i use knownhost with cpanel/linux mysql and php.

when we run server with shared hosting. we mostly facing issue os security like c9shell scripts.. as well as ppl hacked database or changed index.html. we do enable php open base dir as well as mo security firewall we do search which user is using find command who is uploading file... but is there any other way to secure server for such hacking issue..

View 8 Replies View RelatedSo I've been using WHMCS for a while, and there's something I'm a little concerned about with the whole keeping customers credit cards for recurring payments.
I've downloaded a backup copy of the database and I see that the passwords and credit card information is encrypted. That's all nice and handy but the CC hash is also stored right in the configuration file. That means that if someone gains access to the server and just grabs the database + config file they would then be able to view all that info correct? Maybe someone who knows a little more about WHMCS can tell me if this is correct or not?
