I've recently installed Ubuntu 10 on my laptop and I'm not sure whether it's safe or not. My question is do I need any antyvirus or firewall to protect my pc against virus, spyware etc.?

So I am wondering if I even need it or if there is something else.
I am behind a firewall already with my router if that helps any.
I guess I am having trouble understanding why virus protection is less necessary.
Do people not write viruses for linux systems?
Using Windows, I always set a Restrictive firewall policy with a third party firewall. But I also had all ports set to Stealth, something that appears to not offer any security benefits (as I've learned from reading Ubuntu forums). I'd like to learn about best security practices (under Ubuntu) for outgoing firewall protection. I will be using the built-in Ubuntu firewall that is configured via Firestarter. Outgoing filtering offers privacy as well as security benefits. But I thought I needed my ports stealthed to be safe too, so I'm open to learning new things.
I wanted to start a poll to find out how many folks use permissive/restrictive, but no polls allowed here apparently.Could Ubuntu users knowledgeable about firewalls enlighten me on whether I should go Outbound-Restrictive and what applications I will need to allow so Ubuntu "housekeeping" is not affected negatively? I basically just use the internet for software updates, web-surfing and e-mail. One question I have is whether there is something comparable in Ubuntu to Window's "DNS Client" service? I always disabled Window's "DNS Client" and forced each application to request port 53 DNS lookups itself.I only had to allow four programs to accomplish all internet traffic that I engage in. I set all other programs/applications to be either Blocked or to have to Ask for an outgoing connection as needed.Here is my former Windows XP setup:
svchost.exe: allow UDP for ports 53, 67, 68, 123 (time) and TCP for ports 80, 443
Avast: allow UDP for port 53 and TCP for port 80
firefox: allow UDP for port 53 and TCP for ports 80, 443
IE: allow UDP for port 53 and TCP for ports 80, 443
Im a long time windows user and just installed Ubuntu 9.10 and have heard that i dont need any antivirus or spyware program on it, also is the firewall enabled by default if there is one and last thing do you need to do things like disk clean and defrag if so how.

View 9 Replies View RelatedI installed TrueCrype 6.3a on my 8.1 Ubuntu. Everything went fine until I got to the part where I need to protect my hidden volume from damaged caused by writing to the outer volume (these instructions: [url] ). I can't find the checkbox to "Protect hidden volume from damaged caused by writing to outer volume". The closest thing I can find is an option to "Protect hidden volume when mounting outer volume". Intuitively these don't sound the same to me. There are 2 difference between my setup and the instructions; 1) the instructions appear to be written for Windows and not Linux. 2) I am using a file volume and not a partition volume.
Does anyone know where the option is to protect the hidden volume when writing to the outer volume?
is there a way to make a password key-ring for a list of specifications, specifically; all the applications relating to preferences. I'm running Ubuntu 11.04, I'm the only user, I disabled all login password requirements because they were annoying me and I'm cool with anybody using any of my applications as long as they aren't capable of changing my system in any way. Some of the applications I would like to be on the list include the terminal, the network connections preferences, the keyboard preferences. I wan't to be prompted for a password before opening these programs

I work in a relatively small organisation of about 30 people (but with a complex network) and we've been looking to move our firewall to Microsoft's Threat Protection Manager on a mostly Windows network. I've been thinking we should have an IDS/IPS inside the firewall and I've been thinking about Snort in NIDS mode but have some basic questions:
1. Can anyone recommend a good web GUI for Snort?
2. Is it advisable to run both on the same machine? (Both from a POV of security and resources.)
3. Would Snort add any real benifit to using TPM?
So I forgot how to do something in Compiz and I quickly Googled it to find the answer. On the first or second link I clicked, a pop-up box opened from Firefox saying that I should scan my computer. Immediately, I pressed the X button, but a page started to load that tried to "scan" my computer. I closed out Firefox and re-opened it. I did the exact same search again on Google, but I clicked on the cached view of the site. It was harmless enough--a blog with some ads on the side of the page. I'm assuming that it was one of the ads that somehow must have taken over the page.
Anyway, I know that the discussion of anti-virus programs is not anything new, but I would like to know if this virus may have affected Ubuntu. What would you guys recommend in this case?Also, after running the update manager, I received a pop-up box asking if I would like to update Grub. Is this a normal part of the update, or could it be a virus? I'm a bit paranoid, being from the land of Windows.
I read some articles about viruses in Linux and about some antiviruses which work in Linux and delete Windows viruses but I still don't understand: is there any antivirus which specializes in Linux viruses? Even though there are very little of Linux viruses, I know.

I don't find a debian package of it and don't know how to install tar.gz and the tutorials don't help a lot. Are there other antivirus solutions which are good for cleaning Windows OS but work on Linux/WINE? I wonder if I can install antivirus software in WINE and scan with no problem the hard disks.

I tried Linuxshield, but the version of kernel I have is too new. I spent two days trying to make it work, but it gives me an error continually, no matter what I do when I try to install it. If there is anyone on the same kernel version that has had success with a virus protection software.
View 11 Replies View RelatedI would like to install Linux based AntiVirus Server with Windows Clients. As per the existing setup, all Windows machines are using "demo" or "evaluation" copy of antivirus & all antivirus softwares are not same on all windows computers.
Someone is using Trend-Micro ,other is using Avast. Due to above listed problem,i want to implement Linux Based Free AntiVirus Server,which will be connected directly on the internet. The Linux AntiVirus server will updated it's database from Internet automatically.
Inside the Linux Server,all Windows PC's are connected in a same Local Area Connection. All windows XP computers will fetch the updated data from the Anti Virus Server. Also,i am searching MAIL RESPONDER OR POP UP Windows,when any virus found on any client machine. My company needs Cost Effective solution & Linux is the best solution for this.
Recently I had a Java exploit on Windows. Luckily Microsoft Security Essentials identified and removed it. Such things can happen on Linux as well, from what I've heard. Why does Linux offer no such detection?

I can smiply go to switch users. when the list of users logins are shown all i have to do is click on my user name and it allows me into my account without typing in a password. I can lock the computer manually or wait for it to time out it doesn't matter. the switch users method allows me to bypass the password protection.
I have a Suse11 box with 2 network cards:
I have squid as a proxy on the Suse box, and with the default firewall I have to enable masquerading to allow clients on the eth3:1-3 to send and receive mail through the Suse box. I found the Suse firewall completely inadequate (all P2P software/connections are allowed once you enable masquerading) and had to install ConfigServer Security & Firewall. In die configuration of csf I could get my way around getting smtp to work for the eth3:1-3 clients, but pop3 connections does not go through the box. I know I need to allow port 110 and 995 to masquerade of NAT (or something) and then the same for port 22
I used Avast webfilter (proxied webtraffic through Avast) when running Windows. Sometimes Avast would alert and "protect" me from being infected by a compromised website. NOTE: Avast would alert even absent clicking any links. Just viewing the page could result in infection. Should I be running some kind of proxy webfilter for protection? My understanding is that Firefox can be compromised and this can in turn compromise Ubuntu.Are these kinds of threats specific to Windows running Firefox, or Firefox per se. If Firefox per se it seems like I need some sort of Proxy webfiltering like Avast provides.
View 9 Replies View RelatedI'm running Thunderbird with Enigmail, and I have this very annoying problem. When I open an encrypted email for the first time, it asks me for my key password. It then remembers my password. This is fine for a few minutes, since I don't want to enter the password every time if I look at seven emails in five minutes. However, I WOULD like it to EVENTUALLY forget. At the moment, it doesn't even forget if I shut off Thunderbird. I have to restart my computer, in fact.
The preferences for Enigmail don't help. I've configured it to remember the password for 0 minutes, for example. I don't know how to edit the preferences for gpg-agent or anything else like that.

View 9 Replies View RelatedI am new to the Ubuntu/Linix world (less than a week).
I have tried the search, but have had difficulty finding threads on this.
Can someone recommend an excellent firewall to use with Ubuntu?
I have a VPS (Ubuntu 8.04 server eition) and as such am stuck with using a software firewall.
i currently have UFW installed.
I would ideally like to have my firewall be a little rude, or rather just not polite. I know what i am asking will break the RFC, but i consider this ok due to the security benefits.
I would like to have my firewall
1) ignore (eg drop without responding)all packets that dont start with a syn flag
2)for all other traffic that is currently blocked, have it dropped (again drop it without responding)
If there are any other rules you can think of i would like to know them. I already have only the services i want open and the rest blocked.
