I currently have a dual boot - Ubuntu 10.10 (the latest one) and Windows XP.If I install Ubuntu to also run within Windows will I be just as protected against malware as when I boot directly into Ubuntu?
View 3 RepliesI wanted to know if I install Ubuntu on my virtual PC on Windows 7 is it just as secure?
If I have a keylogger or some spyware will that affect the session I have running on the Virtual PC? Can they still steal my passwords?
yesterday I ordered some software on the Net.Early this morning, I got a call from my bank someone else tried to charge to my debit card.I called the company I ordered from to alert them and they assured me it had to be my computer security because theirs was checked, upgraded regularly and above reproach.Fortunately, the bank caught it in time and my account wasn't debited. After I assured them I didn't order anything from Bed, Bath and Beyond, the bank shut down my card and I had to apply for another.
I was shocked. You hear about it but never imagine it will happen to you. I began to wonder and worry if it was because I was using Linux and it wasn't as secure as Microsoft.I'm isolated in a very small town in West Texas so I order some things on the Net.I loaded the full version of Ubuntu "Lucid Lynx" 10.04 from a 4 disk set and downloaded all the upgrades; almost five hundred and set everything up the way I wanted. My question is: Are there programs running among the Ubuntu build to assure a secure transaction on the net or do I have to load others and a fire wall like Windows? That's one of the reasons I left Microsoft behind was the "Auntie-viral" programs took over and almost became a competing system.
Does anyone know if it would be possible to do this? I read of people who have run Windows Server 2003 under qemu.. but i was wondering if i could get it easily to work in a secure sandbox, so i could run it as a internet server - knowing that it was secure and no one could then hack my computer.
View 1 Replies View RelatedI'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.

View 4 Replies View RelatedI have a problem using PGP encryption. I am running Windows 7 operating system. I have PGP working perfectly fine when running manually through DOS mode (cmd.exe): gpg -ase --always-trust --batch --passphrase myphrase --output c: estdir estfile.csv.pgp -r someword c:estdir estfile.csv
Now the problem happens when I am trying to run same script in Perl in the browser (Perl + IIS are installed locally on my PC). The error I am getting is: gpg: no default secret key: No secret key gpg: C:\testdir\testfile.csv: sign+encrypt failed: No secret key
From what I understand, the secret key is created under my user profile. IIS runs under some default user name, so it does not see the secret key. I am not sure how to solve this problem.
venturing into unfamiliar territory so I'm hoping someone can help me and make things a little more understandable for me. I have setup Postfix on a standalone server connected directly to the internet. I have got inbound and outbound email working for the most part, but I am worried about security.My fear is that if I leave port 25 open to the outside world spammers will find this and start relaying mail through it and eventually blacklisting the IP attached to this box.
For now, I am hosting mail for a single domain and single user (me) with a few aliases. I plan on expanding to IMAP and SMTP access from the outside at some point, but for now I've been using Mutt in a shell and it's fine for my needs for now.
Here are my current Postfix settings:
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases

View 1 Replies View RelatedI 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?
A) Pc-bsd
B) Ubuntu
And also which OS is more reliable?

View 9 Replies View RelatedI 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.

View 9 Replies View RelatedI 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).
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.

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?

View 5 Replies View RelatedA 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.
I have very little security and networking experience. What can I do to make my computer more secure?
View 5 Replies View RelatedIs 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.
View 3 Replies View RelatedI recently installed Xubuntu on a 5+ year-old Acer Aspire laptop. In spite of how the root, swap and home are volumes in an LVM2 group on top of a fully-encrypted harddisk, it's quite swift this computer isn't for me, however; it's for my old man. It's been my pet project for the past few weeks, as an exercise in making Linux both highly secure and user-friendly, so that even a technophobe like him could use it without fear of identity theft if it ever gets lost or stolen. I recently shipped it off to him...
The weakest part of security, however, I fear may be the screensaver, which is why I ask. I've searched and searched and cannot manage to find any information on security hardening practices (apart from banal advice such as "always choose a secure password" and "never log in to an X-session as root"). What I want to know is, just how safe is a locked screen? Also...is it technically possible with the right tools to get a core dump of a running computer and thus extract the block device encryption key from memory? I know that your run-of-the-mill thief will just try hitting the power button and throwing in a livedisk, but hey, you never know. Edit: found. [URL] I guess I need to tell him how to set the BIOS password to thwart that sort of thing next time I talk to him on the phone...
