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.

How can i protect my server with outside attack. Will I need to block some ports or I need special tools or script so no one from outside can attack my machine. My machine is working on intranet with local ip only.. No web server or static ip exists. Machine is connected with ADSL router to access internet.

currently I'm fiddling around with mod_security for apache2 configurations on CentOS boxes, right now in a test environment first (i.e. separate non production box).CentOS includes the mod_security "Core Rule Set" by Breach Security Inc, the devs behind that module.So far all's running mostly, logs/auditlogs etc.For simple testing, I made a small php form as following:
Code:
<?php
$link = mysql_connect("localhost",$user,$pass); //un/pw obfuscated for forum post

View 6 Replies View RelatedI create music and usually gets sold world wide. I have some distributors that have been able to access a private server and get the new tunes I make to download via ftp. Well that server is getting full and I was trying to create another directory on my website itself.I created the directory. made the ".htaccess" file. Then I tried to make the htpasswd file but my server just keeps saying no command by that name.
View 8 Replies View RelatedI want to start using videos/music files downloaded from untrusted sources (BT,Sharing Forums, etc.). Haven't made this a habit b4 because of the security risks. I want to take steps to reduce the risk & protect my computer from anything malicious. What are some good choices for this? The biggest step I took so far is using Ubuntu since it's very virus resistant, but other threats do exist out there (rootkits, malicious scripts, etc.). When downloading files from untrusted sources, who knows what may be hidden inside.Some options I'm thinking about:
1) Using a VM (with Ubuntu installed inside) & playing the files inside the VM. If anything malicious happen, it would be trapped inside & I could easily revert to a clean snapshot.
2) Using AppArmor to restrict what the files or program used to play the files can/can't do. AA seems very complicated though.
Are the above overkill? Would it be sufficient enough to just open these files on a non-admin user account since no access to root or sudo?
I am planning a trip for a few days and I will be staying at an inn with Wifi access. All the guests are allowed to use it. A friend of mine has been there, he told me there are several other private spots around the house, i.e. lots of other people using Wifi. My friend told me the inn uses WEP, so who knows how many times their access point has been hacked and accessed without permission...
My concern is that I will be there for a few days with my notebook, I will have to work once in a while, connected to the Internet. Is there some precaution I should take to protect my notebook from intruders? Is it advisable to install a firewall in my notebook (iptables?) or am I just overreacting? Is it possible for one of the guests or neighbors to break into my notebook?
are there any programs that will protect my computer on the Internet. Just started using fed 10 from windows so i am not sure what i need to do. I am using an acer aspire 5630 laptop.

View 1 Replies View RelatedThis might sound really stupid, so you'll all have to excuse my lacking knowledge. I read that USB attacks get more and more common, like putting in an USB stick with a malicious autorun script on it, and it's game over. Can AppArmor protect devices and limit their access to the file system?

View 1 Replies View RelatedToday I've found several attempt to access the following url on my website: [URL] After googleing a bit it seems that in some cases, using this attack, the bag guy is able to change the code in some of your files. it also seems to affect only a certain version of oScommerce. I don't use oScommerce, so I do believe that I'm on the safe side, but it's not the first time that I see some similar attempt of attack on my website. So to protect my self I was wondering if using .htaccess restriction would be enough?

But I do think that these rewrite string are more specificity write to protect oScommerce site. how to protect my web site from such attach and similar?
