QEMU internet security

I'm aware that when using QEMU with a bridged network connection it is important to think about security.
However, with the default networking (-net nic -net user), is there a need to run a firewall on the guest OS? As I understand it, the internet connection is basically using the existing real network through the host computer and is not visible on the network. It would then really not require a firewall right?

You're right. The qemu manual has a nice picture and explanation.

  • Help Needed for Internet Security Driving Test!

    Hi I came up with a few basic rules for family and friends
    that I put together in order to try to prevent them from
    continually installing spyware, toolbars, keyloggers and viruses on
    their computers (and as a result, to try to prevent them from
    continually calling me and asking for my help and advice when they
    did this and things went wrong).
    To all intents and purposes the rules worked well - for a
    while. I set it up as a simple RTF document and I added this to the
    start up folder of Windows XP, so that it started every time the PC
    started. However, over time some of them simply learned to ignore
    the rules and to close the RTF document as soon as it opened
    without paying any attention to it at all - and then they went
    about their merry business of installing spyware, keyloggers and
    viruses etc. just as they had in the past.
    So OK, I have to admit I found this deeply frustrating - but
    I also realise that this is the same position that many of us geeks
    are in in that on the whole, most average everyday computer users
    don't have a clue about Internet security.
    Now however things have become a lot more serious for me, as
    I have been asked by a local charity to administer a total of 60
    machines over 2 different sites - and I have also been asked if I
    could provide some form of training with regard to basic personal
    Internet security.
    With this in mind I came up with the idea of an interactive
    CDROM, or Flash based Internet security driving test/tutorial that
    basically covers all of the scenarios I touch on in my rules.
    This tutorial would cover basic things like, if you got an
    email from a representative ex President of an African country
    offering you a share in millions of dollars of stolen money, or if
    you got an email from your bank asking you to verify your security
    details and so on, what would you do? Additionally it would cover
    such things as the abundance of viruses that infest many of the
    porn sites on the net, the way that many games on the Internet that
    are listed as being 'free' (particularly those which are in
    executable file format) are often just vehicles for more spyware
    and viruses also - and about the dangers of chat lines, of spoof
    security warnings on web sites and so on.
    I have included my list of rules below which should hopefully
    give you an idea of what I'm trying to do. Be warned though, the
    wording is deliberately harsh and perhaps a little extreme (and as
    a result maybe not entirely 100% accurate) but you must realize
    that I am, or was trying to give myself the easiest time possible
    and the least possible problems. So you may well find things you
    disagree with in it - but overall if someone followed these rules,
    they probably would be less likely to run into problems than
    someone who did not follow them might.
    The thing is however that (as I said) I would like to
    formalise these rules somewhat in the format of some kind of
    interactive tutorial/web security driving test. Unfortunately I
    have no experience with flash - and little knowledge of HTML or
    anything like that. I also know that the language for these rules
    isn't quite right, in that it probably isn't suitable for a formal
    office type environment.
    I had in mind that the tutorial would show some realtime
    examples of some of the things I have been talking about (which I
    assume would only be possible in Flash?) or perhaps rather like a
    readers digest multiple choice type thing, with screenshots
    depicting the various scenarios in question. (Like a screenshot of
    a flash animation on a web page saying 'You have won a prize!!!'
    What would you do? a) click on the ad, b, ignore it, or c) phone
    all of your family and friends informing them of your good fortune
    before doing anything.' etc.
    So I was wondering, are there any good hearted charitable
    souls out there who might be willing to help out to put a tutorial
    like this together?
    Again I remind you that it really is for a charity
    (specifically the Depaul Trust in the UK, which helps young
    vulnerable people find secure accommodation, provides educational
    opportunities and helps them to find employment). The requirement
    would be that all staff and students pass the Internet security
    test before being granted Internet access.
    I know this might be time consuming - but again all I can do
    is appeal to the sense of kindness and helpfulness of this
    community and hope that someone who does have some experience in
    these maters might be willing to help.
    Alternatively could anyone suggest a simple easy to use
    software package that would allow a relative n00b like me to put
    together a tutorial like this on my own? Or perhaps it is possible
    that some free online tutorial like this already exists?
    In any case, any help at all would be appreciated.
    PS,
    Here are the rules I have that I referred to above.
    http://download305.mediafire.com/b6ndmljht1bg/29bbnnbz2uz/internet+rules.rtf

    Dennis, when I look at the subject three clips (EI 1250, EI 640, and EI 320, respectively, and in that order) as presented in the camera, I see exactly what I have expected all along -- three different-brightness images that are progressively brighter from the EI 1250 exposure to the EI 320 exposure.   So, am mystified why when I open these images (clips), say, in RAW Viewer, wherein I have thought that I would see the same progressive brightness differences allowing me to experiment with reducing brightness to deal with noise reduction, all three of the images present completely alike in brightness.

  • Problem with Rescue and Recovery after installing Norton Internet Security 2010

    Hi all.
    It's my first time in this forum.
    I have a problem, with Rescue and Recovery, after installing Norton Internet Security 2010 on my T43.
    The message I get it:
    "Rescue and Recovery is unable to back up the file 'C:\Documents and settings\all Users\Application Data\ Norton\ 00000082\00000109\000003c1\cltMLS1.bat' Because the file is either corrupted or being used by another application. Please close any application that could be using the file.
    I tried to close the Norton but I couldn't find how.
    Tanks

    Hi and welcome to the forum,
    the reason for this situation is, that the antivir files are protected from being modified.
    This is the reason, why this file cannot be backed up. I assume, that you would get much more such messages, as there are surelly multiple files files, that are protected like this.
    So the solution is to block folders from being archived. Please start RnR application and in the configuration set this folder as the excluded one.
    This will skip the backup of this file and will fix your situation.
    Please let me know, if you have covered this.
    Cheers

  • I have The latest Firefox installed on an older Dell, and the CA security suite thru my ISP, which takes all my CPU and causes everything to freeze when I try to access it's features. I need a free internet security program that does tax my system so much

    Have older Dell Dimension 32/bit with Win XP Prof 2002. I have installed CA security suite from my ISP, which is a huge program and uses 100% of CPU on start-up & shut down, slowing everthing to a snails pace. I have removed evrything I don't need using 30 day free Revo Unistaller Pro, but when I try to access CA's Firewall to add programs to the exception rule, it will open, then freezes along with Firefox tabs and anything else. Can't even shut down from start menu. I want to get rid of CA(although it is a good program, it's too big), and go back to using my Win Firewall(or another better free firewall that's good for more than 30 days trial) and some other free internet security program that is easy, runs in the background and doesn't take all my resources and isn't just a 30 day free trial till you buy the program. I am also trying to install a wireless adapter so I can drop my ISP and use the free city/county signal as no work for 20 months!
    == This happened ==
    A few times a week
    == Trying to access CA security Suite Firewall

    I am the original poster, and I got rid of CA Security Suite & and loaded the Avast! which has some great features even on the freeware. No more crashes or freezing & yes I think there is a problem with CA & Firefox, but am not sure what it is. CA was a big time hog. I also got rid of my ISP and installed a Intellinet Wireless G PCI Card & now am completely wireless on my PC. Faster by far than what I was paying $50/month for & I use my Windows Firewall.

  • I have a problem with my Internet Security and the new Firefox, where can I get the previous version which I had before my system crashed?

    Hi I use CA Internet Security Suite which checks ALL pages and searches, but it does not work with this version, also I wish to use Goggle Toolbar which ALSO does not work with this version where can I get the previous version? As my harddrive crashed I have had to install windows 7 and this version doesn't seem to allow me to change my homepage, why is this? Cheers Ernest

    You can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html
    Mozilla are working to prevent Mac users with non-compatible systems from getting the notification about Firefox 4, and also not displaying the "Download Firefox 4" button on http://www.mozilla.com

  • Is there a way to reinstall the Internet Security Suite?

    I've had to install a completely new hard drive into my computer, so naturally I don't have the security suite on it. I've had the suite installed on my old hard drive, which I lost to a power surge, and even then I had lost the suite before. However, I was able to reinstall it by myself on the old hard drive once, but now I can't do it that way with my new hard drive. Do I have to call Verizon to send someone to reinstall it for me?
    I ordered the Internet Security Suite when I got FiOS last year, so I've already had it. I just need to get it on this hard drive without having to pay for it again.
    Any help?
    P.S. I'm not exactly sure how I was able to reinstall it that time before, so don't ask. Thank you in advance.

    Grace_bestowed,
    No you don't need anyone to come out. Go to www.verizon.net then click on My account. From there you will click the manage my broadband Essentials and that's right where it will be to allow you to install it.

  • Qosmio G30 freezes upon Norton Internet Security 2008 startup

    Norton Internet Security 2008 will freeze my computer as soon it tries to load and the only way to go on is to restart the system by pressing the on/off-button.
    My notebook is a Toshiba Qosmio G30-177 (Model No. PQG32E-02G022GR) with Vista Ultimate and NIS2007 pre-installed. I have no problems with this NIS2008 version on my other notebook (Qosmio F10 - PQF10E-02300JGR, WinXP MCE).
    NIS2007 runs fine on my G30 and I do not have any problems at all, but newer versions of NIS seem to get in conflict with my system:
    1. I am able to install and run the new version, download all updates and adjust the settings. Maybe one or two days later my computer will freeze after start exactly when the tray icon of NIS appears. For a couple of seconds there is just no response of the system at all and the LED's of my notebook show that all HD activity has stopped. After being idle for these couple of seconds, the cooling fan will start to operate at maximum power, creating a tremendous noise I never experienced before, not even while the CPU was running at 100% for some time due to other programs. Forcing a restart is all I can do.
    2. Now this time, I successfully restarted my notebook again (took some attempts) and it suddenly did not freeze. Then I disabled firewall and auto-protect permanently, so there was no freezing upon startup and I just had to manually activate both firewall and auto-protect after start. In order to prevent freezing again after reboot, I always disabled NIS before shutdown. For the next one or two days this workaround was quite successful.
    3. All of a sudden, after one or two days, this workaround is going to become useless, because the system starts to freeze again at the very moment the tray icon appears. In this case, restarting has no effect at all, and NIS will continue to freeze at startup. I also tried to prevent NIS form starting by no longer allowing ccApp.exe to automatically run upon start (administrative tools > system configuration > "startup" tab). This is successful and my notebook is able to start normally, but if I later try to start NIS manually, it will freeze again.
    I had this problem since NIS2008 was just released, so I thought that meanwhile a Windows or Norton update might have fixed the issue, but this weekend I gave NIS2008 another try without success. I am almost sure that the problem is not caused by any other software than Windows and/or Norton, because I also tried to install NIS after a full system recovery, thus having only pre-installed NIS2007 and Vista on my notebook. I did use the Norton removal tool and followed the deinstall instructions before trying to install the newer version of course.
    My last hope was that the NIS2009beta version somehow would not freeze my system, but it does. It does not matter if I try to run 2008 or 2009beta version, the problem is exactly the same.
    What really drives me almost crazy is the fact that NIS runs perfectly for some time, then needs a rather small workaround, and then after some time totally refuses to work. In these couple of days I did not change any system settings, install or deinstall any programs or did anything that I felt could conflict with NIS...
    So far, I have no idea of a solution and have to use NIS2007 again.
    Does anybody know how to solve this problem?

    Hi !
    I use NIS since 2001 and never had any serious trouble with this software.
    There could be some compatibility problem, but I don't think that Vista is causing it, because otherwise a lot more people should have the same problem. Even the installation of all current Windows, NIS and Qosmio updates did not solve it. Of course I tried to get help using Symantec's Support and their user forums, but without success. This problem seems to be a rare one (unfortunately for me). I tested the NIS2009beta and even though it's a new version, the PC freezes again when this program starts. And this made me think that maybe a service or setup by Toshiba causes the problem and other Vista users are not affected. It's a strange thing that the pre-installed NIS2007 version is running fine...
    Cheers,
    Mario

  • Question about internet security...please help!

    Hi everyone,
    I have a question about the macbook's internet security.
    A few days ago I became aware that my sibling was using a laptop for internet use at my house which he got from a person that I do not trust. He is very computer-savy and we're worried that he may have installed some form of spy ware on that laptop and in turn, may have tried (or succeeded) in accessing my Macbook through some form of spyware. My house is hooked up with a D-Link wireless router, and at the time, it had no internet/access-password.
    So my question is, could this person have accessed my computer and personal information remotely by and through the laptop that my sibling got from him. I was under the impression that Mac's have very strong firewalls, but I have also heard that as long as he knew what he was doing, he could have accessed my computer. I don't have a wireless "network" set up at my house, I just simply use the router for internet. But my sibling told me that this guy was his "network administrator" which leads me to believe that he must have had remote access to the laptop.
    Can anyone with knowledge on this problem please weigh in and let me know what I need to do to confirm that no one has accessed anything from my macbook.
    Thanks!

    One option if you want to be extra safe is turning on FileVault (System Preferences -> Security), which will encrypt everything on your computer so that if somehow someone does gain access to your computer they will have a next to zero chance of being able to read anything they get from your computer. You have to have a lot of extra hard drive space on your computer to turn it on though.
    Also, a "network" is just a connection between computers, regardless of the internet is involved or not. So when you connect your computer to the router which gives you the internet, you are putting your computer on a network. Now I believe that in order for this person whom you don't trust to gain remote access to your computer, they would have to have more information such as an IP address for your computer, through the router in order to get to it.
    One thing I think is very important to consider that isn't on the technical side of things is something called "Social Engineering" which is a form of cracking, or hacking. You can do your own research, but in a nutshell Social Engineering is getting people that have access to something I'm trying to hack to give me information. For instance, this person you don't trust could be giving your brother the computer in the hopes that he will download something through your router to that laptop which could give him IP addresses and other information. And then when he gets that laptop back he could scan it for useful information and your brother wouldn't know he did anything wrong at all. The best way to avoid this is purely education and communication. Even if your brother doesn't share the same suspicions about this person, surely he will understand the need to be careful and smart when it comes to sharing personal information in the digital world.

  • Internet Security Suite does not work with Vista 64 bit

    After attempting to use the Chat Help, twice, and spending hours in queue before getting kicked off, I finally called Support to find out why my new Vista computer was not running the Internet Security Suite that I downloaded.  Yes, I found the link to "download to a second computer" and went thru all the steps.  Got lots of positive feedback: little bars were filling in letting me know I was 40%, 72%, 100% done, etc..  Was given a window allowing me to Run or Don't Run the software.  It all seemed to go very well.  However, when the "download and installation" was complete, there was no new software running anywhere on my computer.  Couldn't find it in the Control Panel, the Start menu, or the system tray.  Called Support and spent at least 30 minutes on the phone with a "technician" (and I use that term VERY loosely) who had to have major assistance from a co-worker before he could even start screen-sharing with me and, during the course of our time together, made the following brilliant remarks:
    Upon seeing my desktop wallpaper (which is a lovely photo of some cliffs and a lake - and it came with Vista), he wanted to know what the picture was.  Not where it was taken, but just what it was.  His exact comment was "Does your screen always look like that?".  I had to dig deeper to determine if he was asking about a particular icon or some other computer related concern that he saw (he was "technical support", after all), but he was just asking about the stupid photo.
    He couldn't find the Control Panel in the Start Menu until after trying several times, and then he couldn't navigate to the Programs area very well (I had to give verbal hints as to where it was), and his brilliant comment then was "I really need to go to my mom's house and get on her new laptop and try out Vista."  Can you believe that Verizon has technical support folks who have never used Vista?  It's not like Vista just came on the market yesterday!!
    So, when he finally decided that he was not going to be able to help me, he didn't offer me any other recourse.  He just stated over and over that he was not sure how to solve this issue.  Oh, and this was after I re-downloaded ISS (again, "successfully").  I had to ask if there was someone else there who could possibly help me.  He offered to put me on hold (for the 2nd or 3rd time at this point) to check around.  When he returned to the phone, it was obvious that someone else was operating the mouse in the screen sharing mode because the operator moved confidentially around the screen and went immediately to system properties and saw that I am running Windows 64 bit.  The other operator then told my guy to tell me that ISS only works with Windows 32 bit.  Their final resolution was that I should call billing on Monday and end my subscription.  I think that may be the only good advice I was given that day.
    So, am probably going to renew my trial version of Norton on this new computer and remove ISS from the laptop and put Norton on there as well.  Apparently, they are up to date with this fancy new technology.  At least they probably know about sophisticated and highly technical stuff like desktop wallpaper.

    I have been trying to get somewhere with this Internet Security Suite...and now have come to the conclusion this is not going to work.  Now running Vista 64 bit, and have gotten nothing but the run around to try to complete the downloading of the program.  I've contacted Verizon Tech Support...then tell me that this works with the 64 bit but I need to contact Windows as there is a glitch and they give you the steps to get thru it.  Windows advises me to contact Verizon again as there are no problems with the OS.  Also have contacted Radialpoint and once again nothing...Obviously the Secuirty is not compatible with Vista 64 bit yet, which I just can't believe like you said...it's not like it was just yesterday this OS came out.  My frusteration comes from nobody steps up to take any responsibility as to what the problem is.  If it is not compatible yet then say so and not waste my whole weekend trying to get a straight answer.  I have other computers that I am currently using the service on and do like the program, but as for my Vista 64 bit looks like I may go to Macafee for protection.  It just amazes me as big as Verizon is and as popular this Vista has become they are not on the ball in keeping up with technology.

  • Windows Security Suite does not recognize Verizon Internet Security Suite

    Windows Secuity Suite does not recognize that the Verizon Internet Security suite on one of my PC's is running and keeps popping up aWindows Security Alert. The Firewall is enabled within Verizon Internet Security suite.
    My other PC's don't have this issue.
    All PC's are running Windows Vista Home Premium.
    Any ideas?
    Cheers,
    Mark

    well that error message is saying that Windows security center no longer supports the way that the VISS is reporting. Which means that even though VISS is working and it is even reporting its status to WSC. WSC doesnt recognize it anymore. Likely one of the windows updates made the change. I can see the fight comming now. Verizon is going to say. Its working and if the other program doesnt support it, too bad. And windows is going to say the same thing in reverse. My guess would be that it will probably stay that way unless Verizon or Microsoft get enough complaints to make a change in the recognition system.
    But the good news is that VISS is running and protecting you. The WSC just doesnt "speak the same language" anymore and cant understand the message from VISS saying "I'm up and running"

  • Norton Internet Security No Longer Fills in my Passwords in FF 4.0

    When I upgraded to Firefox 4.0 I can access web pages fine, however, Norton Internet Security no longer fills in my passwords on designated log-on screens. You need to make this check every time you upgrade Firefox because I had the exact same problem when I upgraded to Firefox 3.0 and it took almost a week before it was fixed. During that time I had to use Internet Explorer :(

  • Verizon Internet Security Suite - says subscription ended but account is active

    After several attempts with Verizon reps to get our online backup increased from 50gb to 150gb, Verizon finally figured it out and now we have more backup memory.  However, in the process of doing that, Verizon went and terminated our internet security suite.  After chatting with a rep to get VISS turned back on, our account on My Verizon shows that it is active again; however, the VISS on our PC still indicated that our subscription has ended.  In an attempt to fix the problem, we first removed the existing VISS from the PC then reinstalled it....but after reinstall, VISS is still saying the subscription has ended, and we need to renew our subscription.  I'm at the end of my rope in dealing with Verizon on this and thought I'd try the forums to see if I can get an answer.  Any ideas on how to get VISS to get working again?  I'm worried about the PC being exposed since VISS is not active...

  • Flash CS4 not working with Windows 7 64bit and Kaspersky Internet Security

    I have a new i5 core computer running Windows 7 64bit retail. With Kaspersky Internet Security 2010 installed Flash CS4 becomes so unresponsive that it is completely unusable. Uninstall KIS and it works absolutely fine. I've already read on another forum that someone else is experiencing the same issue with the same combination of products. Is anyone else having this problem amd if so how did you solve it? I've posted on the Kaspersky forum with no solution thus far.
    Does Norton work OK with Windows 7(64) and CS4?

    *** PROBLEM SOLVED ***
    Taxxem you are a star. Ideed turning off 'disable external service control' and disabling 'self defense' under 'settings  -options' does indeed bring Flash back to life. Disabling self-defense had the most impact (and causes Kaspersky to grumble somewhat) but disabling external service control also had an impact, albeit much smaller. I'll post this solution against my Kaspersky forum post and hopefully they will do something about it.

  • Trouble connecting playbook to windows PC when using AVG Internet Security and USB cable ?

    I have spent ages trying to get my PC (windows 7 64bit ) to talk to the Playbook. I found the following:
    Windows device manager sees the playbook and will let me back up and restore but not to see the files on the Playbook. Desktop software says problem with connection. On the "computer" window it shows drives but not the Playbook. Only hard drive and DVD drives. Looks like AVG is blocking the USB and as yet they have not come up with a solution and latest software wont let you manually configure the firewall other than allow and block (previous versions allowed you to config inbound and outbound rules)
    Elsewhere on the forums a solution was provided but it meant leaving the firewall set to "off" or "allow all" which really is a waste of time having a firewall at all.
    Please try this and see if it resolves your problems, It sorted it for me !
    Remove AVG Internet Security 2014
    Load AVG antivirus 2014 ( freeware) so now you are OK for antivirus protection
    Load Microsoft Security Essentials (freeware) so now you are  OK for firewall protection
    Playbook now talks and can be configured, also the contents of the playbook drive can be seen alongside your PC drives and DVD drives in the "computer" window of your PC  The playbook drive has now been allowed to be mounted where as it was blocked before
    I know how frustrating this can be I have spent ages on it ..so give it a try

    The USB-parallel cable needs a driver that supports Windows 7 x64 in addition to the driver the printer needs.  Additionally make sure the port settings are correct, usually the port will be something like USB001: or USB002: for the USB-parallel port. Some cables may provide a virtual LPT port such as LPT3:.  Check the documentation for your unit for details.
    The posts here list models of USB-parallel ports folks here have had success with in Windows 7.
