Security :: How Secure Is Ubuntu / Firefox

Jun 14, 2010

Newbie here,
I'm thinking of moving mostly to linux to get away from the security holes in Windows. And I have some questions...

How secure is Firefox for doing online banking?

Sometimes I have run into a situation where the bank doesn't support anything but Windows explorer when accessing my accounts. Can this be gotten around safely in Linux?

If so, How?

Ubuntu Security :: Malware Scanner For The Firefox Browser?

May 21, 2010

So I downloaded a movie from megaupload and a pop up came up with [URL]....that bounced me to[URL]..but that webpage did not display. Normally, on Windows, I would have an anti-virus that would likely give me some sense of good or bad websites. On Ubuntu, I am not quite sure. Do I need a malware scanner for the firefox browser? I have the standard package from the 10.04 distro with the latest updates...

Fedora Security :: Firefox Browser Cannot Find Server

Jan 10, 2010

Browser can't find server at att.yahoo.com so no internet. My folding at home client with Stanford can't download {an upload went ok}. I have 2 other fedora boxes & 3 windows boxes thru the same router and they are all fine.

I can manually ping Stanford ok,
Add/remove software within fed. works ok.
I can type in 192.168.0.1 & get the page for my router
The only thing I did between working & not working was to install
Nvidia Cuda driver for my GTX275

My guess is something in the firewall got tweaked. but I've compared it to 2 working boxes & nothing jumps out at me.

Security :: Ways To Secure Sendmail Or Secure Alternatives To Send Mail

Dec 1, 2010

I'm an Oracle DBA and started working for my current employer about 4 months ago. This past weekend an alert re: FS space brought my attention to /var/spool/clientmqueue (full of mail re: cron jobs) and the fact that sendmail is not running on our Linux servers.I'm told that the IT security team deemed sendmail too vulnerable so we don't run it.Aside from FS filling up and missing notification of issues with crontab entries, I'm concerned that we may be missing notification of potential issues. In other Unix/Linux environments I've seen emails from the print daemon when it experienced problems with specific jobs.

Are there other Linux facilities aside from cron and lpd that use email to advise the users of possible issues? Are there ways to secure sendmail or secure alternatives to sendmail? My primary need/desire is to make sure that emails regarding issues on the server get to the appropriate users. Secondary goal would be to have the ability to use mailx to send mail out. There is No need/desire to receive mail from outside.

Ubuntu :: Upgraded Firefox - Error "Your Browser Is No Longer Supported. Please Upgrade To A Modern Browser."

Aug 2, 2010

i just updated from karmic 9.10 to lucid 10.04 using the online upgrade option. so far everything is working great. the only issues i am having seem to involve firefox. when i visit videos i get the message "your browser is no longer supported. please upgrade to a modern browser." i am running 3.6 "canonical" so it is "modern". i am able to watch videos after i close the message. it's just an annoyance to get this message every time i view a video.

next, is on some websites (like this one) it will not supply my login info. but on a few sites (like ebay) it does supply my login info. not sure why some sites work while others don't. the info is there when i look under my saved passwords....

Ubuntu :: Duplicate Source Entries In Karmic?

Mar 23, 2010

I used to be able to resolve this problem by simply opening my sources.list file and doing a search and delete, but now Ubuntu appears to have two completely different methods of handling sources. What is is the simple solution? I would really like to have everything all in one place.

Code:
W: Duplicate sources.list entry http://ppa.launchpad.net karmic/main Packages (/var/lib/apt/lists/ppa.launchpad.net_sunab_ppa_ubuntu_dists_karmic_main_binary-i386_Packages)
W: Duplicate sources.list entry http://ppa.launchpad.net karmic/main Packages (/var/lib/apt/lists/ppa.launchpad.net_mozillateam_firefox-stable_ubuntu_dists_karmic_main_binary-i386_Packages)
W: You may want to run apt-get update to correct these problems

Ubuntu Security :: Better Way To Secure My Server?

Jan 26, 2010

I set up my ubuntu server with iptables that only allows ssh in the input chain (and of course established connections) with only the mac adress of my laptop allowed to connect, set up a key with a long passphrase and installed pam_abl plugin. ICMP echo is blocked by default.

The only problem is i log all other attempts to connect to the server and i see a lot of traffic going to ports 445 and 5900.

My question is: Is there a possibility that these attempts could succeed and is there any way to further ensure this server?

Ubuntu Security :: How Secure Can Website Really Be

May 25, 2011

I want to set up a website that hosts very confidential business information. The info needs to be accessed by multiple people in different geographical regions. The entire website would require the high security (ie: there are no little sections that are publicly viewable). While the site will be run with Ubuntu server, I will be hosting it in Amazon's EC2 cloud.

So, if I use the HTTPS protocol with an SSL certificate, am I pretty well reaching the most secure possible situation? Are there any concerns with using the EC2 solution? Obviously there are a LOT of variables involved with maintaining website security, but I want to know if HTTPS is the current best bet (in addition to all the "best practices" of securing a site) or if there is a more robust way of securing content.

Ubuntu Security :: Secure My Server From The Internet

Feb 3, 2010

I am running UFW, which is set to deny everything but SSH on port 22, OpenVPN on port 1194 and HTTPS on port 443. SSH is set to only allow private key logins, and the root account is disabled. I have AppArmor running for all of my daemons (OpenVPN, Apache2, OpenSSH) and I have Fail2Ban running.

Is there anything else I can do to secure my server from the Internet (it is directly connected, there is no NAT between the Internet and my server).

Ubuntu Security :: Secure File Transfer

Feb 4, 2010

If I need to get a file to someone I could place it on the server and somehow automate an email telling them there is a file available. They could login to the server based on their email address and a randomly generated key combination and down load the file.I also need it to preform the same function going the other way. Login into my server and place files going to me.

Ubuntu Security :: How Actually Secure Launchpad Application

Aug 20, 2010

I always hear 'do NOT install anything from anywhere except the official repositories'. But I find a lot of great apps that are not included in repositories and would like to ask. How actually secure launchpad is? Are the codes reviewed by anyone? How do I make sure that a piece of software is not going to harm my Ubuntu? If I add a PPA for some program I won't going to check it's code every time it updates or am I being too cautious?

Ubuntu Security :: Logging Into The Secure Website?

Oct 8, 2010

A friend of mine has a private forum setup so he and I can communicate back and forth so we don't have to send emails. The link is a "https://" so I'm assuming it's secure. I'm a newbie to ubuntu and I have already switch 3 of my computers at home to ubuntu.

I'm using Ubuntu 10.04 and google chrome as my browser. When I log into his forum it pops up with a screen saying "The site's security certificate is not trusted" and I always click proceed anyways. I'm not worried about this because I'm 110% sure that it's his website that I'm trying to access. My question/problem is it also pops up with a little box telling me to enter my Username and Password every time. When I was using WindowsXP, I had to enter this info once and then I wouldn't have to enter it again.

Ubuntu Security :: Secure P2p Instant Messaging

Feb 5, 2011

Is there a program already set up to do this? Probably similar to WASTE (URL...), though waste's client is currently unsupported on the newest version of ubuntu (make error having to do with char* or something). Preferably windows and linux supported. Another thing that could be of use would be a local ssh chat. For example someone connects to my box either as me or as another user and runs 'hiben' and a window (or i ran a command or something and have a window open for it) pops up that we can chat in. Something other than single line messages.
