Schneier on Security: Linux Security
I'm a big fan of the Honeynet Project (and a member of their board of
directors). They don't have a security product; they do security
research. Basically, they wire computers up with sensors, put them on
the Internet, and watch hackers attack them.
They just released a report about the security of Linux:
=====================================...when is secure, secure?
I wrote a custom authentication handler for PureFTPD, using a combination of
authentication methods, for about 4 different types of users.
So far, from testing it, it does look to work properly, and does it's job
pretty well (and fast). I use #!/usr/bin/perl -W as well as use Strict, and
use warnings, and the code returns no errors or warnings when run.
I am right to presume that this basically only really tells me the my syntax
and structure of the application is right? What's a good way to see whether
it is actually SECURE... There is a couple of lines of...security too secure
Summary: security too secure
The security thing won't let me in this sight no matter how I accept,
confirm, get certificate, etc.

Thanks to this group and all the high tech individuals who frequent it I
have learned how to protect my PC from the inside out. But what about
security risks to my info 'before' it gets to my computer? Like my mail

Anyone have experience with this package?
I'm just learning Ubuntu Linux. Is this too big a chunk for me to bite

Welcome to the official EnGarde Secure Linux Community website.
EnGarde Secure Linux is a Linux server distribution that is geared
toward providing a open source platform that is highly secure by
default as well as easy to administer. EnGarde Secure Linux includes a
select group of open source packages configured to provide maximum

F-Secure's Linux Security 7.00 Linux virus scanner contains a critical flaw
which may cause it to delete directories on a computer. F-Secure warns that
the software with the Client Edition keycode should not be used, and has
initiated a product recall. An entry in F-Secure's Linux blog explains that
slip-ups in quality control allowed a flaw to slip though the net which
makes the scanner delete the /var directory and any contained subdirectories
when the tool is operating in client mode.
Users of the software can apparently check whether their installation...Linux security
I read this article, 'CommsDesign - Linux and Security: Mission
Impossible?' (http://tinyurl.com/yjfnqqa) and it brings up some good
points. With the kernel being at about 11 million lines of code, it is
becoming unmanageable, and thereby more vulnerable.
Anyway, I found it an interesting read. Don't think I agree with all

July 28, 2008 (Computerworld) This story originally appeared in
Computerworld's print edition.
If there is a Holy Grail in the information security industry, it surely is
the answer to the question, "How secure is secure enough?"
It's a question that many security managers have either avoided answering
altogether or tried to quickly sidestep by throwing a fistful of mainly
pointless operational metrics at anyone who cared to ask.

i have a form in my website which is to be filled by user and that form stores in database(sql server 2005).
but someone told me that anyone can run script in textboxes in that form and can damage database,
so how to avoid such security lack.
it is common practice to use parameterized sql statements or stored procs to insure you are protected from sql injections attacks.
if you concatenate user input directly into a sql statement, then you are at risk.Mike Banavige~~~~~~~~~~~~Need a site code sample in a different language? Try converting it with: http://converte...Password secure...is it secure?
Yes I just got this baby and I LOVE it! Its great. I have stored all my
passwords inside of it (and yes made a few backups from them in secure
locations) How secure is this program really? It uses blowfish to encrypt
the database but how strong blowfish? 128bits? 256? 448?
Anything else I should think about it? I have putted it and its databases
inside PGPdisk just to play it safe...but then again Im a paranoid. :)

I understand that AuthenticationTypes.Secure requests secure authentication using Kerberos or NTLM (??). However, here is a scenario I am trying to understand. Let us say that I am having a regular ASP.NET site - with SSL certificates not installed on the web server. The login sends the request out to an AD server which also does not have certificates installed. However, I have set Secure flag to AuthenticationTypes.Secure. When the username and password data gets transmitted between the application and the LDAP server, how secure are the password and username info?

......... both useful and malicious information can be transmitted via network
connections. Standard solutions protect computers against threats present in
standard network connections, but aren't able to counter threats present in
secure connections. Verifying the contents of a secure connection is
impossible by virtue of its secure nature, as demonstrated by the different
types of protection listed above. As a result, malicious data within secure
channels can cause a significant amount of damage, and sometimes more than if
it were to be transmitted via a standard, non-s...
