Double check that IPTables loads on start. I made that mistake once. ;) Also, follow the NSA Red Hat guide (if that's what you're using). It's pretty useful. www.nsa.gov/ia/_files/factsheets/rhel5-pamphlet-i731.pdf On Wed, Jun 20, 2012 at 10:27 AM, Littlefield, Tyler <tyler () tysdomain com> wrote:
Hello: I have a couple questions. First, I'll explain what I did: I set up iptables and removed all unwanted services. Iptables blocks everything, then only opens what it wants. I also use the addrtype module to limit broadcast and unspec addresses, etc. I also do some malformed packet work where I just drop everything that looks malformed (mainly by the flags). 2) I secured ssh: blocked root logins, set it up so only users in the sshusers group can connect, and set it only to allow ppk. 3) I installed aid. 4) disabled malformed packets and forwarding/etc in sysctl. This is a basic web server that runs email, web and a couple other things. It's only running on a linode512, so I don't have the ability to set up a ton of stuff; I also think that would make things more of a mess. What else would be recommended? Also, I'm looking to add something to the web server; sometimes I notice that there are a lot of requests from people scanning for common urls like wordpress/phpbb3/etc, what kind of preventative measures exist for this? -- Take care, Ty http://tds-solutions.net The aspen project: a barebones light-weight mud engine: http://code.google.com/p/aspenmud He that will not reason is a bigot; he that cannot reason is a fool; he that dares not reason is a slave. ------------------------------------------------------------------------ Securing Apache Web Server with thawte Digital Certificate In this guide we examine the importance of Apache-SSL and who needs an SSL certificate.
