  • Securing a local server physically

    - by Daniele
    We are an online business. We have a very powerful server with hard disk mirroring in our office that we are using for a variety of internal business-critical functions. We want to keep that machine in our office but we want to make sure it is as secure as possible (within reason). Obviously we are already backing it up everyday off-site. My question is more about not-too-expensive physical measures to protect the machine against thieves and disasters such as fire. What would you suggest?

  • How can I read password protected Word files on OS X ?

    - by Ohad
    I receive Word documents by mail and read them using the built-in Gmail reader. Sometimes the documents are password protected and I need to obtain access to a Windows machine with Office installed in order to read them. Is there a quicker / less hassle requiring method ? I don't want to have to install Vmware / Parallels nor Office on my fresh and sterile macbook.

  • Blocked connections passing through firewall. What is wrong?

    - by Kiranu
    In our company we have a small business router (Cisco RV082) on which we are using its standard configuration (block all incoming traffic). We also have an SMTP relay configured (using WS2008R2) so that our internal applications can send email through google apps (which requires authentication). The thing is that the server was being used to send spam. We fixed the problem by only allowing the server to relay email from our internal IP address range (10.0.0.0/16). My concern is that there was a way by which external IPs connected to the network and that underlying problem has not been fixed, but I cannot imagine how these machines connected. Any thoughts?

  • Modern open source NIDS/HIDS and consoles?

    - by MattC
    Years back we set up an IDS solution by placing a tap in front of our exterior firewall, piping all the traffic on our DS1 through an IDS box and then sending the results off to a logging server running ACiD. This was around 2005-ish. I've been asked to revamp the solution and expand on it and looking around, I see that the last release of ACiD was from 2003 and I can't seem to find anything else that seems even remotely up-to-date. While these things may be feature complete, I worry about library conflicts, etc. Can anyone give me suggestions for a Linux/OpenBSD based solution using somewhat modern tools? Just to be clear, I know that Snort is still actively developed. I guess I'm more in the market for a modern open-source web console to consolidate the data. Of course if people have great experiences with IDS' other than Snort I'm happy to hear about it.

  • Application runs fine manually but fails as a scheduled task

    - by user42540
    I wasn't sure if this should go here or on stackoverflow. I have an application that loads some files from a network share (the input folder), extracts certain data from them and saves new files (zips them with SharpZLib) on a different network share (output folder). This application runs fine when you open it directly, but when it is set to a scheduled task, it fails in numerous places. This application is scheduled on a Win 2003 server. Let me say right off the bat, the scheduled task is set to use the same login account that I am currently logged in with, so it's not because it's using the LocalSystem account. Something else is going on here. Originally, the application was assigning a drive letter to the input folder using WNetGetConnectionA(). I don't remember why this was done, someone else on our team did that and she's gone now. I think there was some issue with using the WinZip command line with a UNC path. I switched from the WinZip command line utility to using SharpZLib because there were other issues with using the WinZip command line. Anyway, the application failed when trying to assign a drive letter with the error "connection already established." That wasn't true and even after trying WNetCancelConnection(), it still didn't work. Then I decided to just map the drive manually on the server. Then when the app calls Directory.Exists(inputFolderPath) it returns false, even though it does exist. So, for whatever reason, I cannot read this directory from within the application. I can manually navigate to this folder in Windows Explorer and open files. The app log file shows that the user executing it on the schedule is the user I expect, not LocalSystem. Any ideas?

  • Files deleted. What could have happened?

    - by jjfine
    I'm having a weird issue today. I was writing and testing out some simple cgi scripts this morning when I realized that I couldn't run them from one of the other computers on the (windows) network. So I had my network admin come in and take a look at what was going on. A few minutes later a co-worker came in and told me that a bunch of files he was working with as well as a bunch of others (all *.c files) on the network drive got deleted. He also noticed some strange apache_dump_500.log.txt files in the same directories where the files got deleted. The apache_dump_500.log.txt files all look like this: REDIRECT_HTTP_ACCEPT=*/*, image/gif, image/x-xbitmap, image/jpeg REDIRECT_HTTP_USER_AGENT=Mozilla/1.1b2 (X11; I; HP-UX A.09.05 9000/712) REDIRECT_PATH=.:/bin:/usr/local/bin:/etc REDIRECT_QUERY_STRING= REDIRECT_REMOTE_ADDR=<my computer's local ip> REDIRECT_REMOTE_HOST= REDIRECT_SERVER_NAME=<my computer's domain url> REDIRECT_SERVER_PORT= REDIRECT_SERVER_SOFTWARE= REDIRECT_URL=/cgi-bin/trojan.py I looked and I don't have any trojan.py in my cgi-bin folder. And all my apache logs are clean. Windows event logger seems to not have any traces of what happened either. My httpd.conf: http://pastebin.com/Yny2Yh8v I think we've got some kind of virus that added this trojan.py file to my cgi-bin, ran the script, and deleted the script and any traces from the logs. Is this a thing that happens? Any ideas whatsoever would be much appreciated!

  • How to reliably keep an SSH tunnel open?

    - by Peltier
    I use an SSH tunnel from work to go around various idotic firewalls (it's ok with my boss :)). The problem is, after a while the ssh connection usually hangs, and the tunnel is broken. If I could at least monitor the tunnel automatically, I could restart the tunnel when it hangs, but I haven't even figured a way of doing that. Bonus points for the one who can tell me how to prevent my ssh connection from hanging, of course!

  • How to set up Drupal Plugin Manager on MAMP in a secure way?

    - by Andrei
    Hi, I use MAMP PRO as global webserver. First of all, is it a good idea? Secondly, my objective is to run a Drupal website with as easy management as possible. Now I want to use Plugin Manager module to install additional modules and themes for my website. It wants to use ftp for that, and I know that if I open access to FTP port then IT-department guys will come to me and ask to shut it down. So I wonder if there is a way to allow Plugin Manager to install modules, having the port 21 closed somehow?

  • rhel configure: limit root direct login to systems except through system consoles

    - by zhaojing
    I have to configure to limit root direct access except system consoles. That is, the ways of telnet, ftp, SSH are all prohibited. Root can only login through console. I understand that will require me to configure the file /etc/securetty. I have to comment all the tty, just keep "console" in /etc/securetty. But from google, I found many peoples said that configure /etc/securetty will not limit the way of SSH login. From my experiment, I found it is. (configure /etc/securetty won't limit SSH login). And I add one line in /etc/pam.d/system-auth: auth required pam_securetty It seems root SSH login can be prohibited. But I can't find the reason: What is the difference of configure pam_securetty and /etc/securetty? Can anyone help me with this? Only configure /etc/securetty could work? Or Have I to configure pam_securetty at the same time? Thanks a lot!

  • This operation has been cancelled due to restrictions in effect on this computer

    - by Dan
    I have this HUGELY irritating problem on Windows 7 (x64). Whenever I click on ANY link (that exists on a Word document, Excel or Outlook), I get an alert box with the message: This operation has been canceled due to restrictions in effect on this computer I have been scouring my settings and the Internet for a solution, but to no avail. What is the reason for this problem? It even happens when I click anchors in word document. That is, I can't even click on an entry in a Table of Contents to go to the appropriate page - I get this same error then. Is this a Windows 7 thing? Is there any way to turn this off?

  • Afraid computer is not secure

    - by Michael James
    I have recently implemented LastPass as a secure password manager. When I changed the password for my email address an associated account ([email protected]) that i had never seen before came up in association with my account. It asked me if i wanted to change password for my account and the "smithfaketester" account I used Google to try and find out what is going on, but came up empty. I am afraid my computer is bot net-ed. Any input is greatly appreciated. I have used google to search for reasons why this fake account was coming up but I did not find any meaningful info.

  • Is there a way to tell if a program like KeyScrambler is first in the list of keyboard driver filter

    - by Brian T Hannan
    I recently found a program called KeyScrambler which appears to be a keyboard driver filter that intercepts keystrokes and jumbles them up for you so keyloggers aren't able to get your keystrokes while visiting your online banking sites. I was wondering if there is a way to tell if KeyScrambler is always first in line for the keyboard driver filters or if another driver filter could be installed and intercept the keystrokes before it gets to KeyScrambler.

  • Updating snort rules automatically

    - by Matt Simmons
    I've been working on getting my snort machine up and running, and working through Snort IDS and IPS Toolkit. The authors suggest using Oinkmaster, but on that website, the last update was February of 2008. That seems sort of...odd. Maybe there haven't been any issues with oinkmaster in the past year and a half, but it made me wonder if there was another solution that I don't know about. If you use snort, do you automatically update your rules, and if so, how?

  • How to send a batch file by email

Is this possible by email?

  • Barring connections if VPN is down.

    - by Majid
    I have a VPN account and use it for sensitive communication. However the VPN connection sometimes is dropped while my main connection to the internet is still alive. The pages I visit through VPN are on HTTP (not secure) and have javascript code which pings the host every minute or so on a timer. So it happens sometimes that the VPN connection is dropped and yet js sends a request to the server (with the cookies). How could I restrict connections so they only happen if the VPN is live? Edit - Some required details were missing OS: Windows XP SP2 Browser (mostly used): Google Chrome Firewall: Windows default Sites to filter: not all traffic but all in a list of sites like abc.com, xyz.com

  • Host's sys admins - can they view files?

    - by FullTrust
    Hi, Just a quick question. When using shared hosting, can system admins (employed by the host) access your files and read your database connectionstring details? Can they also access your database, and view the files, without a connectionstring? I'm assuming there's a certain level of trust, but is this possible/common? Thanks

  • Encrypted WiFi with no password?

    - by Ian Boyd
    Is there any standard that allows a WiFi connection to be encrypted, but not require a password? i know that (old, weak) WEP, and newer WPA/WPA2 require a password (i.e. shared secret). Meanwhile my own wireless connections are "open", and therefore unencrypted. There is no technical reason why i can't have an encrypted link that doesn't require the user to enter any password. Such technology exists today (see public key encryption and HTTPS). But does such a standard exist for WiFi? Note: i only want to protect communications, not limit internet access. i get the sense that no such standard exists (since i'm pretty capable with Google), but i'd like it confirmed. Claraification: i want to protect communcations, not limit internet access. That means users are not required to have a password (or its moral equivalent). This means users are not required: to know a password to know a passphrase to enter a CAPTCHA to draw a secret to have a key fob to know a PIN to use a pre-shared key have a pre-shared file to possess a certificate In other words: it has the same accessibility as before, but is now encrypted.

  • How can I get a virus by just visiting a website?

    - by Janet Jacobs
    It is common knowledge that you can get a virus just by visiting a website. But how is this possible? Do these viruses attack Windows, Mac and Linux users, or are Mac/Linux users immune? I understand that I obviously can get a virus by downloading and executing a .exe in Windows but how can I get a virus just by accessing a website? Are the viruses programmed in JavaScript? (It would make sense since it is a programming language that runs locally.) If so, what JavaScript functions are the ones commonly used?
