• Redundant Router and Load Balancing vs. DDoS attack

  - by colgatta

  With a small server farm at a hoster with great support and conditions, I worry about the increasing number of DDoS attacks against this hoster (not my web project, but other clients on the same location). I have booked a redundant router and load balancer as managed service with this hoster to share the load with all the dedicated servers. However, I was lost again today because another one's project was attacked with DDoS for hours :-( Each hour means hundreds of dollars loss whenever my adserver and tracking is not reachable. Even time-out advertising have to be paid by me but can not be resold to my clients without the servers being available. All the time, the servers, the load and traffic is OK and health, but no chance to keep this stable/online if the hoster is vulnerable. Anyone has ideas or suggestions how to protect - even against DDoS?

• How to exclude a sub-folder from HTaccess RewriteRule

  - by amb9800

  I have WordPress installed in my root directory, for which a RewriteRule is in place. I need to password-protect a subfolder ("blue"), so I set the htaccess in that folder as such. Problem is that the root htaccess RewriteRule is applying to "blue" and thus I get a 404 in the main WordPress site (instead of opening the password dialog for the subfolder). Here's the root htaccess: RewriteEngine on <Files 403.shtml> order allow,deny allow from all </Files> <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> I tried inserting this as the second line, to no avail: RewriteRule ^(blue)($|/) - [L] Also tried inserting this before the index.php RewriteRule: RewriteCond %{REQUEST_URI} !^/blue/ That didn't work either. Also inserted this into the subfolder's htaccess, which didn't work either: <IfModule mod_rewrite.c> RewriteEngine off </IfModule> Any ideas?

• Can't edit a specific document in Word 2007

  - by Benjotron

  I have a document in Word 2007 that seems to be read only. There are forms in the document that I can type in, but I can't edit or reformat the rest of the document. There is probably a setting somewhere I can flip to make it editable again but I can't find it for the life of me. FOLLOW UP: The "Protect Document" button only had "Unrestricted Access" checked, this was one of the first things I checked. However, when I tried checking "Restrict Formatting and Editing" it brought up the Restrict Formatting and Editing sidebar, which stated: This document is protected from unintentional editing. You may only fill in forms in this region. With a stop protection button on the bottom, which of course solved the problem. I think that menu item just has a bad name, it should be "Restrict Formatting and Editing Options or Settings"

• Root certificate authority works windows/linux but not mac osx - (malformed)

  - by AKwhat

  I have created a self-signed root certificate authority which if I install onto windows, linux, or even using the certificate store in firefox (windows/linux/macosx) will work perfectly with my terminating proxy. I have installed it into the system keychain and I have set the certificate to always trust. Within the chrome browser details it says "The certificate that Chrome received during this connection attempt is not formatted correctly, so Chrome cannot use it to protect your information. Error type: Malformed certificate" I used this code to create the certificate: openssl genrsa -des3 -passout pass:***** -out private/server.key 4096 openssl req -batch -passin pass:***** -new -x509 -nodes -sha1 -days 3600 -key private/server.key -out server.crt -config ../openssl.cnf If the issue is NOT that it is malformed (because it works everywhere else) then what else could it be? Am I installing it incorrectly? Update I tried changing the certificate attributes, but to no avail: openssl genrsa -des -passout pass:***** -out private/server.key 2048 openssl req -batch -passin pass:***** -new -x509 -nodes -sha256 -days 3600 -key private/server.key -out server.crt -config ../openssl.cnf

• "This file came from another computer..." - how can I unblock all the files in a folder without having to unblock them individually?

  - by Schnapple

  Windows XP SP2 and Windows Vista have this deal where zone information is preserved in downloaded files to NTFS partitions, such that it blocks certain files in certain applications until you "unblock" the files. So for example if you download a zip file of source code to try something out, every file will display this in the security settings of the file properties "This file came from another computer and might be blocked to help protect this computer" Along with an "Unblock" button. Some programs don't care, but Visual Studio will refuse to load projects in solutions until they've been unblocked. While it's not terribly difficult to go to every project file and unblock it individually, it's a pain. And it does not appear you can unblock multiple selected files simultaneously. Is there any way to unblock all files in a directory without having to go to them all individually? I know you can turn this off globally for all new files but let's say I don't want to do that

• erratic audio levels on windows vista

  - by old retired dude

  I'm somewhat hard of hearing. I've been listening to my windows Vista machine with a pair of headphones so I don't annoy the others. I have 2 issues: 1) the volume varies enormously depending on the source. Having a windows alert occur while I am listening to a DVD or Youtube is a painful experience. Is there a preferred way to set all the different audio controls so I have a more constant volume? I already have lowered the volumes of the windows alerts. 2)Is there a way to limit the volume of my headphones to protect what is left of my hearing? Is there a software solution or should I be going for a hardware limiter? thanks retired dude

• openSuse full disk encryption

  - by djechelon

  I'm a proud Suser. I'm about to reinstall 12.2 on my ASUS N76VZ (UEFI x64 laptop). Since I'm very sensitive about laptop security against theft or unwanted inspection, I chose to use BitLocker with USB dongle in Windows 7. When installing Suse the last time I found that only the home partition (separated from root) was capable of being encrypted. Does Suse offer a full disk encryption solution like BitLocker that I haven't discovered yet? Or is encrypting home partition the only way to protect data? Encrypting only home is feasible as one stores personal data in home, but I still would like to encrypt the whole thing! Also, using a hardware token (no TPM available) for unlocking is preferred to password, if possible! Thanks

• how to warehouse data that is not needed from sql server

  - by I__

  I have been asked to truncate a large table in sql server 2008. The data is not needed but might be needed once every two years. It will NEVER have to be changed, only viewed. The question is, since I don't need the data on a day-to-day basis, what do I do with it to protect and back it up? Please keep in mind that I will need to have it accessible maybe once every two years, and it is FINE for us if the recovery process takes a few hours. The entire table is about 3 million rows and I need to truncate it to about 1 million rows.

• SQL Server store procedure encrypt is safe?

  - by George2

  I am using SQL Server 2008 Enterprise on Windows Server 2003 Enterprise. I developed some store procedure for SQL Server and the machine installed with SQL Server may not be fully under my control (may be used by un-trusted 3rd party). I want to protect my store procedure T-SQL source code (i.e. not viewable by some other party) by using encrypt store procedure function provided by SQL Server. I am not sure whether encrypt store procedure is 100% safe and whether the administrator of the machine (installed with SQL Server) still have ways to view store procedure's source codes? thanks in advance, George

• Encrypt shared files on AD Domain.

  - by Walter

  Can I encrypt shared files on windows server and allow only authenticated domain users have access to these files? The scenario as follows: I have a software development company, and I would like to protect my source code from being copied by my programmers. One problem is that some programmers use their own laptops to developing the company's software. In this scenario it's impossible to prevent developers from copying the source code for their laptops. In this case I thought about the following solution, but i don't know if it's possible to implement. The idea is to encrypt the source code and they are accessible (decrypted) only when developers are logged into the AD domain, ie if they are not logged into the AD domain, the source code would be encrypted be useless. Can be implemented this ? What technology should be used?

• What are the essential considerations for setting up systems in a location with unreliable power?

  - by dunxd

  I deal with a lot of remote offices located in parts of the world where the local grid power supply is unreliable. Power can go off anytime with no warning, with outages ranging from minutes to days Power fluctuation is wild, with spikes and brown outs Currently the offices will have some or all of the following: A generator, with an inverter, or some sort of manual switch A big UPS or battery array connecting a number of devices Several smaller APC UPS with computers attached Low cost Voltage Regulators sometimes connected between mains and UPS or device. I know that each of these things needs to be appropriately rated for the equipment to which it is connected (although I am not sure how to calculate the correct rating). The offices will generally have the following equipment (in varying quantities): some sort of internet connection device (VSAT router, ADSL modem, WiMax router) Cisco ASA 5505 firewall a bunch of PCs printers one server I don't seek to replace the advice of an electrician, but in some of these locations they only answer the questions you ask them, so I need to make sure I have enough understanding of the essentials to protect equipment from damage, and possibly get through some power cuts.

• Dealing with LDAP failure when using it for PAM/NSS?

  - by Insyte

  I use a redundant pair of OpenLDAP servers for PAM auth and directory services via NSS. It's been 100% reliable so far, but nothing runs flawlessly forever. What steps should I take now so I have a fighting chance of recovering from failure of the LDAP server(s)? In my informal testing, it appears that even already authenticated shells are largely useless as all username/uid lookups hang until the directory server comes back. So far I've come up with only two things: Do not use NSS-LDAP and PAM-LDAP on the LDAP servers themselves. Create a root-level account on all boxes that only accepts publickey authentication from our local subnet and protect that key well. I'm not sure how much good this would do me as once I'm logged in, I suspect I wouldn't be able to accomplish anything since all the userid lookups would be hanging. Any other suggestions?

Same scenario with compass. There is a config.rb file within the folder which also starts to download it. How can i prevent this behaviour? How can i deny downloading specific files?

• Windows terminating system processes

  - by jemper

  To be sure nobody will answer me with advice on not trying to terminate critical (system) processes - I'm relatively experienced in programming and Windows in general - I'd know what I'm doing so far. So there are these processes that can't be terminated with taskkill - system processes in general. But there also is, for example my Anti Virus program that makes itself "unterminateable". How can I access and mainly terminate system processes under windows? (kill.exe by Microsoft doesn't work) How do processes like anti-virus programs protect themselves? How can you turn them off again, then?

• Recommend a web file sharing software please.

  - by Baczek

  I'm looking for a web platform to put company files at. My requirements are: should be accessible via a browser should be open source must be installable (dropbox is a no-go) must have an option to put a access time limit on a file must perform garbage collection automatically after a file expires must be able to mark files as public or private an option to protect a file via a pin-code for users without accounts in the system would be nice to have The problem is I don't even know what to search for - all my googling results in either complete groupware solutions or p2p file sharing software. If such a thing doesn't exist, please don't hestitate to say so, so I can crawl to a corner and cry myself to sleep. TIA

• 3 Root accounts in MySQl database

  - by hairbymaurice

  Hello, I have managed to get mySQL running under Ubuntu 8.10, I am now diligently trying to secure the database and am adding passwords for the root users. My question: I have a root user under the host "kickseed" with no password set I have no idea what kickseed is as the database is installed under localhost, on searching around i have discovered that this is something to do with the ubuntu OS itself. Is it safe to delete this user account from MySQL or is it used for something by the OS? If i need to keep it should i /can i protect it with a password? Also i have another root account under the host IP 127.0.0.1 again can i delete this? My absolute preference would be to have only one account with root access but i do not want to delete these accounts if they are necessary. Thanks for tolerating a newbie Regards Hairby

• Outlook Registry Key Damaged; Tried "Fix It" and lost everything

  - by Ray

  My outlook 2007 (on Windows 7 64 bit) worked fine for two weeks. I then installed a printer/scanner/copier and the Outlook Window wouldn't open. I went to Microsoft's website and found a page that said my registry key was damaged. The page had a link to a Fix It program. I ran the program and it looks like all my Outlook data was wiped out. Can I get the data back? For future reference, how should I protect myself if the key goes bad again? Do you think I should unistall Outlook and re-install?

• "save the changes" message after removing the protection from workbook Excel 2010

  - by abbasi

  Some time ago I protected the Excel 2010 file from the path File Protect workbook Encrypt with password and gave it a password. Now that I removed that password via below method: Open the workbook and use Save As In the lower right of the file window will be "Tools" Choose "General Options" Clear the password. Save over your old file. the file is openable without wanting a password. But the problem is when I open it and close it immediately, even without moving the active cell, the message "Do you want to save the changes you made to 'test.lsx'?" appears. While there hasn't occurred any changes to that file so why I face this message any time I want to close the file? Hasn't the file been corrupted?

• Can't type text into table cell when form is protected in Word 2002

  - by Gus

  I created several tables in an Word 2002 document to act as a form for users to fill out. In some cells I added check boxes and dropdown lists for people to select options from. When I click on the Protect form button the check boxes and dropdowns become active; however, I can't type anything in the other cells. If I click in an empty cell it automatically moves to the next checkbox. When I unprotect the form then I can type in the empty cells but then checkboxes and dropdowns become useless. I know that the user can double click on the checkbox and then manually select to have it checked, but they can't do this with the dropdowns. What do I have to do to allow the user to type in responses to the tables cells and also select answers from checkboxes and dropdowns? Thanks!

• Several border firewalls in the same network

  - by nimai

  I'm currently analyzing the consequences of multipath connections for the firewalls. In that context, I'm wondering if it's really uncommon to have several firewalls at the borders of a network to protect it. The typical case I'd imagine would be a multihomed network, for which the administrator would have different policies for links from different (or not) ISPs. Or maybe even in an ISP's network. What would be the practical (dis)advantages of such a configuration? Could you provide an example of an existing topology using several border firewalls?

• Is WinRT really as secure as it's made out to be?

  - by IDWMaster

  Prior to releasing Windows 8, Microsoft claimed that all WinRT apps are cleanly removed from your computer after uninstalling them, and that WinRT apps should not interfere with other running applications, because they are ran in a "sandboxed" environment. Microsoft has also claimed numerous times on Channel9 that Windows 8 apps are not ran in a VM. So my question is; are these claims accurate? If the application is not running inside of a VM, how is it possible to protect the system against malicious code at runtime, assuming the attacker was able to bypass the screening process of the Windows Store system? Microsoft allows "native code" in WinRT apps, so wouldn't it be possible (using hand-coded assembly or some odd pointer manipulation trick to call functions outside of the sandboxed environment and interfere with the rest of the system, if it's really "native code" and not some VM?

• I want to run a script when known bluetooth device connects/disconnects to WinXP

  - by Rope

  I have a laptop on my desk at work. I have screensaver timer enabled, so if I'm not using the computer for ten minutes, it will start the screensaver. I also have "On resume, password protect" option checked. This is useful and I want it to be so. However, sometimes I just sit at my cubicle and read some documents without touching the computer. During that time I want my computer to know that I'm there and that there is no need to start the screensaver. I have a mobile phone that is bluetooth paired with the laptop for synchronizing calendars. Is there some way for a script or a program to know that any (or specified) paired device is connected? While typing this out I thought that there might be some registry entries for this. Does anyone have any thoughts on this? -Rope

• protecting a single .exe-file for downloading with htaccess and htpasswd?

  - by ThomasK

  I have this, and only this, in a .htaccess file inside my downloads folder: <FilesMatch "\.(exe)$"> AuthType Basic AuthName "Downloads" AuthUserFile path/to/.htpasswd Require valid-user </FilesMatch> Once I click the link to download a href="fileName.exe">FileName</a>, I'm getting a 500 server error. If I leave out the <FilesMatch>-part; The protection part is working, I guess, since I get the login box. But once I get into the protected area, the 500 server error occurs. What am I doing wrong here? My intention was to protect only a single .exe file to prevent downloaded by anyone. Is there any easier or more correct way of doing this?
