  • Create files on C:\ root gives error 0x80070522

    - by Bryan
    One of our customers has just found a problem when trying to create a file on the root of the C:\ Drive, on a Windows 7 Professional PC. I know they shouln't be keeping files here, but there is a valid reason in this case, so I've relaxed the security on the root of C:\ by giving the group 'users' modify permission. Before I relaxed the security, the user was receiving 'access denied', but now they are receiving the message: An unexpected error is keeping you from creating the file. If you continue to recieve this error, you can use the error code to search for help with this problem. Error 0x80070522: A required priviledge is not held by the client. Googling for this suggests that it is caused by UAC, but how can I get round this when the user doesn't have admin rights on their PC?

  • How to run Firefox in Protected Mode? (i.e. at low integrity level)

    - by Ian Boyd
    i noticed that Firefox, unlike Chrome and Internet Explorer, doesn't run in the Low Mandatory Level (aka Protected Mode, Low Integrity) Google Chrome: Microsoft Internet Explorer: Mozilla Firefox: Following Microsoft's instructions, i can manually force Firefox into Low Integrity Mode by using: icacls firefox.exe /setintegritylevel Low But Firefox doesn't react well to not running with enough rights: i like the security of knowing that my browser is running with less rights than i have. Is there a way to run Firefox into low rights mode? Is Mozilla planning on adding "protected mode" sometime? Has someone found a workaround to Firefox not handling low rights mode? Update From a July 2007 interview with Mike Schroepfer, VP of Engineering at the Mozilla Foundation: ...we also believe in defense in depth and are investigating protected mode along with many other techniques to improve security for future releases. After a year and a half it doesn't seem like it is a priority.

    - by user31788
    Hi, I am using Win 7 64 bit with Firefox as my web browser. Whenever I double click on the FF icon to open my firefox, there would be a chinese website, loading as a tab on my FF. I have checked on my setting for startup homepage for FF under the Tools > Options, it was set to Google as my default page. Can anyone please advise how can I remove the disturbing chinese website from loading on my ff everytime I open my firefox? Thank you very much.

  • Turn Off Google Chrome Annoying Link Hover

    - by Volomike
    I like Google Chrome a lot, but there are two problems I have with it. The Address Bar search history feature that I want to turn off, and the feature where I hover over a hyperlink and in the bottom lefthand corner it shows a light blue hover tooltip about where that link goes. I really don't care where a given link goes and wish I could turn that feature off, even if I have to install a Google Chrome Extension. So, for these two reasons, I will not install Google Chrome as my primary browser and will remain with Firefox. So, is there a fix to turn the annoying link hover tooltip feature off?

  • Locking down a box on the web

    - by glowcoder
    I'm a Java developer who is looking to put a game on the web. I'm not much of a web or server guy, though, and frankly I seem a little lost at where I should start with putting something on the web. My application works fine on my machine, and I'm sure I can make it work fine on any box I put it on. But the security of that box is pretty important. If I sign up for a standard hosting package (let's say from GoDaddy or something) can I simply tell them "make port 12345 open for communication" and let them handle the rest of the security details? If I can't, what are the things I'm going to need to know to prevent my game server from getting hacked to shreds? (Links to solid resources fine by me!) Thanks!

  • Recursive reset file permissions on Windows

    - by Peter Horvath
    There is a big, complex directory structure on a relative big NTFS partition. Somebody managed to put very bad security privileges onto it - there are directories with randomly given/denied permissions, etc. I already run into permission bugs multiple times, and I found insecure permission settings multiple times (for example, write permissions for "Everyone", or false owners). I don't have time to check everything by hand (it is big). But luckily, my wishes are very simple. The most common: read/write/execute on anything for me, and maybe read for Everyone. Is it possible to somehow remove all security data from a directory and giving my (simple) wishes to overwrite everything there? On Unix, I used a chown -R ..., chmod -R ... command sequence. What is its equivalent on Windows?

  • Youtube videos all appear transparent in Chrome (I can see through to my desktop -- see pic!)

    - by kalaracey
    MBP 6,2 :: Google Chrome 13.0.782.32 beta :: Adobe Flash Player 10,3,181,26 UPDATE: only Youtube is affected. Vimeo, other flash, etc. all works great. Hello. I recently had to hard reboot my MBP. After that, I could not watch Youtube videos or (I believe) other flash enabled content. The videos appear transparent, as if there were a "hole" in my browser (Chrome) such that I could see through the hole and see my desktop. I've attached a picture (just picked a random video) Thanks.

  • Is dual-booting an OS more or less secure than running a virtual machine?

    - by Mark
    I run two operating systems on two separate disk partitions on the same physical machine (a modern MacBook Pro). In order to isolate them from each other, I've taken the following steps: Configured /etc/fstab with ro,noauto (read-only, no auto-mount) Fully encrypted each partition with a separate encryption key (committed to memory) Let's assume that a virus infects my first partition unbeknownst to me. I log out of the first partition (which encrypts the volume), and then turn off the machine to clear the RAM. I then un-encrypt and boot into the second partition. Can I be reasonably confident that the virus has not / cannot infect both partitions, or am I playing with fire here? I realize that MBPs don't ship with a TPM, so a boot-loader infection going unnoticed is still a theoretical possibility. However, this risk seems about equal to the risk of the VMWare/VirtualBox Hypervisor being exploited when running a guest OS, especially since the MBP line uses UEFI instead of BIOS. This leads to my question: is the dual-partitioning approach outlined above more or less secure than using a Virtual Machine for isolation of services? Would that change if my computer had a TPM installed? Background: Note that I am of course taking all the usual additional precautions, such as checking for OS software updates daily, not logging in as an Admin user unless absolutely necessary, running real-time antivirus programs on both partitions, running a host-based firewall, monitoring outgoing network connections, etc. My question is really a public check to see if I'm overlooking anything here and try to figure out if my dual-boot scheme actually is more secure than the Virtual Machine route. Most importantly, I'm just looking to learn more about security issues. EDIT #1: As pointed out in the comments, the scenario is a bit on the paranoid side for my particular use-case. But think about people who may be in corporate or government settings and are considering using a Virtual Machine to run services or applications that are considered "high risk". Are they better off using a VM or a dual-boot scenario as I outlined? An answer that effectively weighs any pros/cons to that trade-off is what I'm really looking for in an answer to this post. EDIT #2: This question was partially fueled by debate about whether a Virtual Machine actually protects a host OS at all. Personally, I think it does, but consider this quote from Theo de Raadt on the OpenBSD mailing list: x86 virtualization is about basically placing another nearly full kernel, full of new bugs, on top of a nasty x86 architecture which barely has correct page protection. Then running your operating system on the other side of this brand new pile of shit. You are absolutely deluded, if not stupid, if you think that a worldwide collection of software engineers who can't write operating systems or applications without security holes, can then turn around and suddenly write virtualization layers without security holes. -http://kerneltrap.org/OpenBSD/Virtualization_Security By quoting Theo's argument, I'm not endorsing it. I'm simply pointing out that there are multiple perspectives here, so I'm trying to find out more about the issue.

  • Unable to copy files previously extracted from archives created on a Mac, even after claiming ownership

    - by Maxim Zaslavsky
    I reinstalled Windows on my computer today, and backed up my music to a USB drive. Now, I'm trying to copy the files onto my fresh Windows partition, but I'm unable to copy files that I obtained within my previous Windows installation from zip archives created on Macs. When I try to copy those previously-extracted files, I get an error saying that I need permission from S-1-5-21-...-1000 (a bizarre long ID). The first thing I tried was to take ownership of the files by setting my new user account as the owner, but that resulted in errors saying that I need permission from myself! Some Googling suggested adding antivirus suggestions, so I excluded the relevant folders from Microsoft Security Essentials, but the issue persists. For what it's worth, it seems that some program (so far I've only installed Chrome, Microsoft Security Essentials, and the latest Windows updates) created an empty folder named 601c8c7f0e0c03f725 at the root of my external USB hard drive. What gives?

  • VPN authentication and MAC addresses

    - by zakk
    I have to set up a VPN (various clients connecting to a web service on a server, which is also the VPN server) and I want to make sure that no user will share his/her credentials with third parties. I know that this problem is not solvable completely, but I'd want to set up some additional security checks... Some idea I have: 1) An additional check on MAC address, but... are MAC addresses preserved thru VPN? 2) Some kind of extra identification of the client (User Agent, open ports, I want to make sure that is the very same client I authorized). 3) I would like to avoid commercial solutions like a security token... I realize it would be the perfect solution, but it will be to expensive, I suppose... Do you feel that these options are viable? Do you have any other ideas? Thanks in advance for your replies!

  • Are there any HTPC-optimized web browsers?

    - by smackfu
    Features that I would ideally include in "HTPC-optimized": Full-screen. Navigable using a remote or the keyboard arrows. Legible at couch distances. Or, to put it another way, imagine the design requirements for Hulu Desktop or XBMC or WMC, applied to a web browser. Opera on a Wii meets most of these criteria but not being HD wastes a lot of potential. If a single solution doesn't exist, is there some combination of Firefox add-ons that will get me there?

  • Browsers with good keyboard support

    - by egon
    What browsers have good keyboard support? That means you don't have to use the mouse so much. Or what is a good setup for browser + keyboard interaction. I know the basic keyboard shortcuts (tab switching, new tabs etc.) but I don't know a good way to switch between links and search areas - usually that means TAB, Shift-TAB one at a time. Is there maybe some plugin that'll add numbers to links and I could just do something like 12 to go to the link 12?

  • How can I get Opera speed-dial and password management features in other browsers?

    - by Howard Guo
    I heavily rely on Opera's speed dial and password management features. Lack of these two features is really stopping me from switching to another web browser such as Chrome or Firefox. Opera's password management has two unique characteristics which I rely on heavily: It saves passwords on all pages, (apparently) despite the page's meta data asking not to save passwords. It offers keyboard shortcut and button to automatically fill in username/passwords and all other fields in a login form, then automatically submit the form. (So I'm only one key/click away from logging into a website) How can I get those functions in other browsers? Thank you! Edit: Reason being that I use other web browsers at work and I wish they could have those functions.

  • Recommended apps for securing/protecting a new desktop machine install?

    - by Eddie Parker
    I'm hoping to harness the collective tips of superuser to gather recommended apps/configurations to keep a new desktop clean, virus free, and hopefully lower software rot. I ask because I've recently come across tools like dropbox, deepfreeze, returnil, etc, and I'm curious what other ones are out there to protect a new box. I personally am interested in Windows, but feel free to comment on whatever OS you'd like, freeware or otherwise. Ideally specify the OS in your answer(s). One answer per program please. Then, rather than duplicate posts, vote for the program if it is already listed. UPDATE: It's been noted that there are other questions similar to this one [1], so I'd ask that these answers focus on security and protection. [1] Related questions: http://superuser.com/questions/1241/what-are-some-must-have-windows-programs http://superuser.com/questions/1191/what-are-some-must-have-mac-os-x-programs http://superuser.com/questions/1430/must-have-linux-software http://superuser.com/questions/3855/must-have-networking-security-tools

  • Why does Django's dev server use port 8000 by default?

    - by kojiro
    (My question isn't really about Django. It's about alternative http ports. I just happen to know Django is a relatively famous application that uses 8000 by default, so it's illustrative.) I have a dev server in the wild that we occasionally need to run multiple httpd services on on different ports. When I needed to stand a third service up and we were already using ports 80 and 8080, I discovered our security team has locked port 8000 access from the Internet. I recognize that port 80 is the standard http port, and 8080 is commonly http_alt, but I'd like to make the case to our security team to open 8000 as well. In order to make that case, I hope the answer to this question can provide me with a reasonable argument for using port 8000 over 8080 in some case. Or was it just a random choice with no meaning?

  • SQLServer 2008 Fails to start under NT AUTHORITY/NETWORK SERVICE account

    - by braincells2pixels
    Not sure what changed but looks like my security credentials have been monkeyed with. Since yesterday evening after I disconnected from our corporate network and rebooted my laptop at home, I am unable to start the instance of SQL2K8. The service is set to run under NT AUTHORITY\NETWORK SERVICE account. The event log records an Access Denied error on the Master.mdf. Switching the account to Local System starts the service but our application runs into security errors. Any clues? TIA

  • cannot add a user to sysadmin role in SQL Server

    - by George2
    I am using SQL Server 2008 Management Studio. The current logon account belongs to machine local administrator group. I am using Windows Integrated Security mode in SQL Server 2008. My issue is, after log into SQL Server Management Studio, I select my login name under Security/Logins, then select Server Roles Tab, then select the last item -- sysadmin to make myself belong to this group/role, but it says I do not have enough permission. Any ideas what is wrong? I think local administrator should be able to do anything. :-)

  • Firefox extension to save tabs?

    - by emzero
    I'm looking for some Firefox (4 or 5) extension to save a group of tabs (better if can be done directly in Panorama view). What I mean by "Save tabs" is not to restore them when Firefox starts. I always have the browser opened and a LOT of tabs (work and personal life related) eating my RAM. So when I'm not working, I would want a way to save those tabs but keep them closed while I still use Firefox. So when I have to start working again, I will restore that saved tabs back again. I know I could use something like Read It Later, but I really need a way to say "hey, save this group of tabs and close them". RIL makes me do it per tab, which is annoying since I'm used to have A LOT.

  • Windows XP app not able to talk to web server

    - by weotch
    My company makes an app built with Adobe Air which talks to our webserver for user authentication. Some users are not able to login. Running Charles Proxy tells us that the "host cannot be found." Loading up the webserver in IE, initially we weren't able to visit the site, we had to add it to trusted sites. My guess is that some security setting is denying our app as well. Does anyone have any suggestions as far as where to make security looser for our app?

  • Which browsers support Window's Low Integrity level?

    - by Ian Boyd
    Normally i like running ie, but it's rendering speed at high-dpi is poor. More recently i've switched to Chrome, but it does not support high-dpi displays. i'm interested in trying other browsers, but they must support protected mode. Are there any other browsers, besides IE and Chrome, that support Mandatory Integrity Levels (i.e. protected mode)? Browsers that i do know about: Browser Protected Mode High-dpi Aware ============== =============== ============== Internet Explorer Yes Yes Chrome Yes No Firefox No No Opera No No Are there any other? And just as an fyi, the clear, unambiguous, non-argumentative, non-subjective, question is: Are there any browsers, aside from Internet Explorer, available for Windows, that run at the Windows Low Mandatory integrity level, and support high-dpi (i.e. non-96 dpi) displays?

  • Automatically download files in Internet Explorer without getting prompted to Save / Cancel?

    - by dimbasint
    I am currently using IE7 with XP SP3. When a webpage download with unknown file type loads, I get a prompt asking me what I want to do with the file. My options are FIND SAVE CANCEL. How do I make it so that I don't get this popup prompt, but Internet explorer automatically downloads the file into a directory I choose without asking? PS. I have already tried Tools Internet Options Security Internet Custom Level Downloads Disable/Enable/Enable, but this doesn't help. Thanks for the reply. Unfortunately I have to use IE. I'm using it in connection with other proprietary software based on IE and its settings. And yes I'm aware it's not a great browser. (This is not for strictly personal use in the browsing sense. )

  • public key infrastructure - distribute bad root certificates

    - by iamrohitbanga
    Suppose a hacker launches a new Linux distro with firefox provided with it. Now a browser contains the certificates of the root certification authorities of PKI. Because firefox is a free browser anyone can package it with fake root certificates. Can this be used to authenticate some websites. How? Many existing linux distros are mirrored by people. They can easily package software containing certificates that can lead to such attacks. Is the above possible? Has such an attack taken place before?
