I run a Linux Debian Lenny server (even though it's in testing it was stable for me). Anyway i have decided i want to nuke it and redo the whole os install etc, as my servers full of usless crap that needs a cleanout etc.

Well anyway i was thinking of going right back to debian. unless someone can convince me otherwise.

The server is my home file server, home web testing server etc, and it's open to the web.

Things i do run on it are:

Apache, mysql5, php5, pureftp, samba, webmin, gnump3d, fireflymediaserver, ssh with no direct root login.

Anyway i am looking for something that will be secure and stable.

I am looking for a nice secure firewall maybe thats easy to understand, ability to support raid etc. I just need an overall secure kernel as well.

whatever you do is never enough and its advisable to take security measures in steps. I would suggest you the following.

1) http://www.rfxnetworks.com/apf.php http://www.rfxnetworks.com/sim.php http://www.rfxnetworks.com/proj.php

2) recompile your kernel with http://www.grsecurity.net/ ( V .Advance)

3) remove all unwanted services,packages,tools, make sure your folders/files ownership are secure (cant really guide here, its vast)

4) feeling adventurous ,enable SE-Linux .

and I got guide here , old one when i was learning to be admin , its got nice tips too https://www.neowin.net/forum/index.php?showtopic=271716

You shouldn't be running a GUI of any sort on a server, it increases the attack vector and makes it less secure. If you want secure, you can always look at OpenBSD, which has only had 2 remote security holes in it's default install in 10 YEARS! PF is also a very nice firewall/queuing/forwarding/packet filtering system. You might also check out FreeBSD, that is a little easier to get used to than OpenBSD. Debain Etch is my distro that I use for my servers, it's pretty secure out of the box, and is also really easy to use.

    • Anthropic pulls Fable 5 and Mythos 5 after US export control order

      By pradeepviswav · Posted

      Anthropic pulls Fable 5 and Mythos 5 after US export control order by Pradeep Viswanathan In April this year, Anthropic launched the Claude Mythos Preview frontier model with state-of-the-art cyber and coding capabilities for a select set of companies around the world. After preparing appropriate guardrails, early this week, Anthropic launched Claude Fable 5 and Mythos 5, its most capable AI models. Claude Fable 5 is for general users and comes with strict safeguards, while Mythos 5 is designed with fewer safeguards for cybersecurity and biology use cases. Today, Anthropic abruptly suspended access to its Fable 5 and Mythos 5 AI models for all customers after receiving an export control directive from the US government. The company received the directive from the government today at 5:21 p.m. ET, and the received letter did not provide any details regarding the national security concern. Anthropic understands that the government became aware of a method to bypass, or “jailbreak,” Fable 5, which might be the reason behind the directive. The order was issued under national security authorities and requires the company to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether they are inside or outside the United States. The restriction also applies to foreign national employees working at Anthropic. As a result, the company has disabled both models for all customers to ensure compliance. Access to previous Anthropic models like Opus and Sonnet is not affected by this government order. The company highlighted that it had developed strong safeguards to reduce the possibility that Fable is misused for tasks related to cybersecurity. In fact, many developers are complaining that the safeguards are going overboard. Additionally, the company worked with the US government, the UK AISI, multiple private third-party organizations, and internal teams to red-team Fable’s safeguards for thousands of hours. Finally, Anthropic noted that no testers have yet been able to find a universal jailbreak on Fable 5. As expected, Anthropic disagrees that a narrow potential jailbreak should lead to the recall of a commercial model used by hundreds of millions of people. It warned that applying this standard across the AI industry could effectively halt new frontier model deployments. Anthropic concluded by mentioning that it is working to restore access to Fable 5 and Mythos 5 as soon as possible and plans to share more details within the next 24 hours.

      Not sure what country you’re in but in many countries you can absolutely jail the sellers behind businesses… in fact I’d say in most countries you can do that
