  • Do browsers allows pages loaded on one tab to access/intercept/inject data in other tabs?

    - by jairo
    I was surprised to hear from this Reuters video that it was possible for a page loaded on one tab to access and/or inject data onto another page loaded on a different tab. TL;DW (too lazy; didn't watch) The interviewee in the video suggests that when doing online banking, the user exit his browser (thus closing all windows) and start a new browser session with just your banking page/tab open. Allegedly, malicious sites can check if you have your banking site open and inject commands onto those sites. Can someone confirm and/or deny this claim? Is it only possible even if there is not parent/child relationship between windows/tabs?

  • In Puppet, how would I secure a password variable (in this case a MySQL password)?

    - by Beaming Mel-Bin
    I am using Puppet to provision MySQL with a parameterised class: class mysql::server( $password ) { package { 'mysql-server': ensure => installed } package { 'mysql': ensure => installed } service { 'mysqld': enable => true, ensure => running, require => Package['mysql-server'], } exec { 'set-mysql-password': unless => "mysqladmin -uroot -p$password status", path => ['/bin', '/usr/bin'], command => "mysqladmin -uroot password $password", require => Service['mysqld'], } } How can I protect $password? Currently, I removed the default world readable permission from the node definition file and explicitly gave puppet read permission via ACL. I'm assuming others have come across a similar situation so perhaps there's a better practice.

  • How can I have APF block script kiddies that mod_security detects?

    - by Gaia
    In one of the vhosts' error_log I found thousands of lines like these, all from the same IP: [Mon Apr 19 08:15:59 2010] [error] [client 61.147.67.206] mod_security: Access denied with code 403.

There is no way someone hasnt thought of this before...

  • Options for PCI-DSS on AWS - file integrity monitoring and intrusion detection

    - by Brill Pappin
    I need to deploy some file integrity monitoring and intrusion detections software on AWS instances. I really wanted to use OSSEC, however it does not work well in an environment where servers can auto deploy and shut down based on load, because it requires server managed keys to be generated. Including the agent in the AMI will not allow monitoring as soon as it comes up because of that. There are many options out there, and several are listed in other posts on this site, however none that I've seen so far deal with the unique problems inherent in AWS or cloud based deployments in general. Can anyone point me at some products, preferably open source, that we might use to cover those portions of PCI DSS that require this software? Has anyone else achieved this on AWS?

  • How does Antimalware Doctor infect computers?

    - by Pyrolistical
    I didn't do anything stupid like run random .exe or visit questionable websites, but as I was just Googling I get infected by Antimalware Doctor. At that point I just shutdown my computer and reformatted, so I didn't check if I had the latest version of Flash or Firefox. Is it possible to get infected just because I didn't have my Flash newer than 10.1 and some random flash ad infected me? There doesn't seem to be any information on how Antimalware Doctor works asides from how to remove it.

  • WinXP password messed up after reset

    - by Mark Flint
    I changed my winXP logon password - but could not get in. Obviously I made the some mistake twice... caps lock or something but couldn't get the password. So I booted into safe mode, when into Users and changed the password. Now I when I restart I can get in at logon with my new password, but the standard screensaver - which used to be the same as my user logon - now is something different. I think it's still the previous one which I couldn't get right. Now when I go into Users (not in safe mode) and try and change the password I can't. It won't accept my new user logon which works fine when logging on. I think this too is still the previous one which I couldn't get right. How can I definitely reset the password so it works at logon, in the control panel/users, and the screensaver?

  • Is it a good practice to run identd in 2010?

    - by Alex R
    I know in the "old days" it was good practice to shut this off. But nowadays I have heard that it improves deliverability of email. In the old days people were not worried about spam (or having their outbound email rejected), so that made sense. Of course, the question is only relevant to servers that send email. What is the current, common practice among discerning Linux admins? Run identd or leave it off? Thanks

  • Grandma's Computer - Can a user that belongs only to the "Users" group in Windows XP install malware, virus or IE addons?

    - by DanC
    I am trying to figure out if having a user in the "Users" group will be enough to prevent her from install unwanted software. The things that I don't want the user to be able to install are: virus malware bandoo stuff Internet Explorer Addons To put you in context, I am thinking of my grandma's computer, I want her to be able to read all her email stuff and attachments, but without the hassle of needing to reinstall the whole computer every few months. The computer will run Windows XP, with some free antivirus. It will not be part of any domain. It is just a home computer. Linux, I have tried making her use it, but she was already accustomed to Windows and was not really an option to have her re-learn where was the shutdown button. So, are these considerations enough to prevent her installing unwanted software? What other options come to you mind? Thanks

  • How to minimize the risk of employees spreading critical information?

    - by Industrial
    Hi everyone, What's common sense when it comes to minimising the risk of employees spreading critical information to rivalling companies? As of today, it's clear that not even the US government and military can be sure that their data stays safely within their doors. Thereby I understand that my question probably instead should be written as "What is common sense to make it harder for employees to spread business critical information?" If anyone would want to spread information, they will find a way. That's the way life work and always has. If we make the scenario a bit more realistic by narrowing our workforce by assuming we only have regular John Does onboard and not Linux-loving sysadmins , what should be good precautions to at least make it harder for the employees to send business-critical information to the competition? As far as I can tell, there's a few obvious solutions that clearly has both pros and cons: Block services such as Dropbox and similar, preventing anyone to send gigabytes of data through the wire. Ensure that only files below a set size can be sent as email (?) Setup VLANs between departments to make it harder for kleptomaniacs and curious people to snoop around. Plug all removable media units - CD/DVD, Floppy drives and USB Make sure that no configurations to hardware can be made (?) Monitor network traffic for non-linear events (how?) What is realistic to do in a real world? How does big companies handle this? Sure, we can take the former employer to court and sue, but by then the damage has already been caused... Thanks a lot

  • Issue changing mysql password on Debian

    - by Sean
    I installed mysql on my Debian server. I couldn't get into the database because it kept saying I put in the wrong password so I looked on the internet and found that I could log onto mysql using the command sudo mysql --defaults-file=/etc/mysql/debian.cnf From there I went typed use mysql;then mysql> UPDATE user SET password=PASSWORD('password') WHERE user='root'; Which I know switched the password because I typed the command select Host, User, Password from user; And it showed the encrypted characters had changed for all three of the root user categories. But I am still not able to login to mysql using mysql -u root -p

  • Do I need a hardware firewall for Win 2003?

    - by user531723
    We have had a Win 2003 server at a co-lo for a while. It is used as a web server and has a very cheap hardware firewall between it and the internet. Ports 3389 and 80 are the only ones forwarded to the server. I am doing some upgrading and wondering if I really need the firewall. Are there any drawbacks to just using the Win 2003 built in firewall to make sure only traffic on 3389 and 80 get through?

  • Beast / CRIME / Beach attack and stopping it

    - by user2143356
    I have read so much on all this but not entirely sure I understand what has gone on. Also, is this one, two or three problems? It looks to me like three, but it's all very confusing: Beast CRIME Beach It seems the solution may be to simply not use compression with HTTPS traffic (or is that just on one of them?) I use GZIP compression. Is that okay, or is that part of the problem? I also use Ubuntu 12.04 LTS Also, is non-HTTPS traffic okay? So after reading all the theory I just want the solution. I think this may be the solution, but can someone please confirm I have understood everything so I am not likely to suffer from this attack: SOLUTION: Use GZIP compression on HTTP traffic, but don't use any compression on HTTPS traffic

  • Public Wi-Fi and software updates

    - by coding4fun
    According to Microsoft, "Never update your software on a public Internet connection." So I have some questions. 1. What if a public Wi-Fi hotspot is the only Internet available, ever? Never update anything? 2. What happens if Windows or some other program is set to update automatically and attempts to do so while you are using a public Wi-Fi? Disable all automatic updates on all software? 3. Will VPN help to secure software updates? If so, how to go about it? Thanks.

  • non-interactive ssh sudo... prompts for the password in plain text

    - by Iain
    I'm running some non-interactive ssh commands. The ssh authentication is taken care of fine through the ssh agent, but if I run a command that requires sudo then the password prompt in my terminal is plain text. For example: ssh remotemachine "sudo -u www mkdir -p /path/to/new/folder" will prompt me for the password in plain text. Does anyone know how I can get it to use the normal secure prompt or that I can pass the password via a switch? (as then I can set up a secure prompt on this side before I send the command) Any help is much appreciated.

  • How can I restore the stored password in firefox 15.0.1 when deleted by error?

    - by Bob Legringe
    I, by error, deleted my stored passwords, using the "Wise disc cleaner 7" program. As I saw on another thread, the passwords are stored in 2 files signons.sqlite and the encryption key file key3.db When opening the file signons.sqlite with the text editor, I can see that the web adresses of the sites belonging to the passwords are still there. They have not been deleted by the "Wise disc cleaner 7" program, and adding a stored password on Firefox just modifies the file. However, Firefox will not display my old stored passwords and neither their respective sites. Is there any way to "undelete" the passwords?

The reason for integrating this filter comes from Spring security FAQs: I'm using Tomcat (or some other servlet container) and have enabled HTTPS for my login page, switching back to HTTP afterwards. It doesn't work - I just end up back at the login page after authenticating. This happens because sessions created under HTTPS, for which the session cookie is marked as “secure”, cannot subsequently be used under HTTP. The browser will not send the cookie back to the server and any session state will be lost (including the security context information). Starting a session in HTTP first should work as the session cookie won't be marked as secure.

  • Keyring no longer prompts for password when SSH-ing

    - by Lie Ryan
    I remember that I used to be able to do ssh [email protected] and have a prompt asks me for a password to unlock the keyring for the whole GNOME session so subsequent ssh wouldn't need to enter the keyring password any longer (not quite sure if this is in Ubuntu or other distro). But nowadays doing ssh [email protected] would ask me, in the terminal, my keyring password every single time; which defeats the purpose of using SSH keys. I checked $ cat /etc/pam.d/lightdm | grep keyring auth optional pam_gnome_keyring.so session optional pam_gnome_keyring.so auto_start which looks fine, and $ pgrep keyring 1784 gnome-keyring-d so the keyring daemon is alive. I finally found that SSH_AUTH_SOCK variable (and GNOME_KEYRING_CONTROL and GPG_AGENT_INFO and GNOME_KEYRING_PID) are not being set properly. What is the proper way to set this variable and why aren't they being set in my environment (i.e. shouldn't they be set in default install)? I guess I can set it in .bashrc, but then the variables would only be defined in bash session, while that is fine for ssh, I believe the other environment variables are necessary for GUI apps to use keyring.

  • Security of logging people in automatically from another app?

    - by Simon
    I have 2 apps. They both have accounts, and each account has users. These apps are going to share the same users and accounts and they will always be in sync. I want to be able to login automatically from one app to the other. So my solution is to generate a login_key, for example: 2sa7439e-a570-ac21-a2ao-z1qia9ca6g25 once a day. And provide a automated login link to the other app... for example if the user clicks on: https://account_name.securityhole.io/login/2sa7439e-a570-ac21-a2ao-z1qia9ca6g25/user/123 They are logged in automatically, session created. So here we have 3 things that a intruder has to get right in order to gain access; account name, login key, and the user id. Bad idea? Or should I can down the path of making one app an oauth provider? Or is there a better way?

  • Is There A Security Risk With Users That Are Also Groups?

    - by Rob P.
    I know a little about users and groups; in the past I might have had a group like 'DBAS' or 'ADMINS' and I'd add individual users to each group... But I was surprised to learn I could add users to other users - as if they were groups. For example if my /etc/group contained the following: user1:x:12501: user2:x:12502:user1 admin:x:123:user2,jim,bob Since user2 is a member of the admin group, and user1 is a member of user2 - is user1 effectively an admin? If the admin group is in the sudoers file, can user1 use it as well? I've tried to simulate this and I haven't been able to do so as user1...but I'm not sure it's impossible. EDIT: SORRY - updated error in question.

  • Is this Java 7 security thread an issue if you have Java 7 installed but not as the default?

    - by user1361315
    I have a MBP with osx mountain lion installed, and I believe from what I read Mac's only ship with Java 6 by default. I'm not at my computer at the moment, but I am pretty sure I have installed Java 7 but it isn't my default java version (I think I installed it and I have to explicitly reference it to use it). Does this mean I am safe from this particular thread? Reference: http://www.pcworld.com/businesscenter/article/261748/researchers_find_critical_vulnerability_in_java_7_patch_hours_after_release.html

  • Problem with Remember Me Service in Spring Security

    - by Gearóid
    Hi, I'm trying to implement a "remember me" functionality in my website using Spring. The cookie and entry in the persistent_logins table are getting created correctly. Additionally, I can see that the correct user is being restored as the username is displayed at the top of the page. However, once I try to access any information for this user when they return after they were "remembered", I get a NullPointerException. It looks as though the user isn't being set in the session again. My applicationContext-security.xml contains the following: <remember-me data-source-ref="dataSource" user-service-ref="userService"/> ... <authentication-provider user-service-ref="userService" /> <jdbc-user-service id="userService" data-source-ref="dataSource" role-prefix="ROLE_" users-by-username-query="select email as username, password, 1 as ENABLED from user where email=?" authorities-by-username-query="select user.id as id, upper(role.name) as authority from user, role, users_roles where users_roles.user_fk=id and users_roles.role_fk=role.name and user.email=?"/> I thought it may have had something to do with users-by-username query but surely login wouldn't work correctly if this query was incorrect? Any help on this would be greatly appreciated. Thanks, gearoid.

  • Authlogic, logout, credential capture and security

    Ok this is something weird. I got authlogic-oid installed in my rails app today. Everything works perfectly fine but for one small nuisance. This is what i did: I first register with my google openid. Successful login, redirection and my email, along with my correct openid is stored in my database. I am happy that everything worked fine! Now when i logout, my rails app as usual destroys the session and redirects me back to my root url where i can login again. Now if i try to login it still remembers my last login id. Not a big issue as i can always "Sign in as a different user" but i am wondering if there is anyway to not only logout from my app but also logout from google. I noticed the same with stack overflow's openid authentication system. Why am i so bothered about this, you may ask. But is it not a bad idea if your web apps end user, who happens to be in a cyber cafe, thinks he has logged out from your app and hence from his google account only to realize later that his google account had got hacked by some unworthy loser who just happened to notice that the one before him had not logged out from google and say.. changed his password!! Should i be paranoid? Isn't this a major security lapse while implementing the openid spec? Probably today someone can give me a workaround for this issue and the question is solved for me. But what about the others who have implemented openid in their apps and not implemented a workaround?
