• What is a quick way to report login/logout times on Windows 2003?

  - by blueberryfields

  I have about a dozen servers, and I am looking to quickly find out all of the login/logout times, for a subset of users, for all servers, during January. Is there a quick, easy way to get this information (faster and easier than manually combing through the security logs)? I would rather not replicate any work - are there any publicly posted tools or scripts that already implement a solution to this problem?

• Running Modern UI/Metro Apps as Administrator in Windows 8

  - by Shail

  I noticed that on Windows 8's Start screen, I could right click a Windows legacy program (A program which runs on Windows XP, Vista and 7), and I could run it as Administrator. However, whenever I clicked on a Windows 8 Modern UI or a Metro app, I didn't have that option. So here are my questions:- Why can't I run the Modern UI apps as an Administrator? Does it make any difference as far as security is concerned?

• Is it worth the effort to block failed login attempts

  - by dunxd

  Is it worthwhile running fail2ban, sshdfilter or similar tools, which blacklist IP addresses which attempt and fail to login? I've seen it argued that this is security theatre on a "properly secured" server. However, I feel that it probably makes script kiddies move on to the next server in their list. Let's say that my server is "properly secured" and I am not worried that a brute force attack will actually succeed - are these tools simply keeping my logfiles clean, or am I getting any worthwhile benefit in blocking brute force attack attempts?

• 40k Event Log Errors an hour Unknown Username or bad password

  - by ErocM

  I am getting about 200k of these an hour: An account failed to log on. Subject: Security ID: SYSTEM Account Name: TGSERVER$ Account Domain: WORKGROUP Logon ID: 0x3e7 Logon Type: 4 Account For Which Logon Failed: Security ID: NULL SID Account Name: administrator Account Domain: TGSERVER Failure Information: Failure Reason: Unknown user name or bad password. Status: 0xc000006d Sub Status: 0xc0000064 Process Information: Caller Process ID: 0x334 Caller Process Name: C:\Windows\System32\svchost.exe Network Information: Workstation Name: TGSERVER Source Network Address: - Source Port: - Detailed Authentication Information: Logon Process: Advapi Authentication Package: Negotiate Transited Services: - Package Name (NTLM only): - Key Length: 0 This event is generated when a logon request fails. It is generated on the computer where access was attempted. The Subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe. The Logon Type field indicates the kind of logon that was requested. The most common types are 2 (interactive) and 3 (network). The Process Information fields indicate which account and process on the system requested the logon. The Network Information fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases. The authentication information fields provide detailed information about this specific logon request. - Transited services indicate which intermediate services have participated in this logon request. - Package name indicates which sub-protocol was used among the NTLM protocols. - Key length indicates the length of the generated session key. This will be 0 if no session key was requested. On my server... I changed my adminstrative username to something else and since then I've been inidated with these messages. I found on http://technet.microsoft.com/en-us/library/cc787567(v=WS.10).aspx that the 4 means "Batch logon type is used by batch servers, where processes may be executing on behalf of a user without their direct intervention." which really doesn't shed any light on it for me. I checked the services and they are all logging in as local system or network service. Nothing for administrator. Anyone have any idea how I tell where these are coming from? I would assume this is a program that is crapping out... Thanks in advance!

• What is the best way to secure MySQL data on a laptop *without* whole-disk-encryption?

  - by GJ

  I need to have the mysql data on my laptop stored in an encrypted state so that in case of the laptop being lost/stolen it will extremely difficult to recover the data without the password. I don't wish to use whole disk encryption, due to the performance impact it will have on other disk-intensive programs' usage. What could be the ideal solution for me balancing security and performance? Thanks!

• Ubuntu server; Should I add a new user or not?

  - by Camran

  On my Ubuntu server, when I do everything now I do it as "root" user. So for example, logging into ftp filezilla, I enter "root" as username... Is this the way to do it, or should I create a users group and add priveliges to the users in that group? Don't know if I should create a new user or not, it works with root just fine, but I don't want any security flaws... Thanks

• Vulnerability research. Is it really research?

  - by Benjamin

  IT security people often say they do "vulnerability research". They defend the idea that they actually are doing some kind of "research". But is searching for vulnerabilities in software real research? A geologist looking for mines in the desert is doing "exploration", not "research".

• Sandbox on a linux server for group members

  - by mgualt

  I am a member of a large group (academic department) using a central GNU/Linux server. I would like to be able to install web apps like instiki, run version control repositories, and serve content over the web. But the admins won't permit this due to security concerns. Is there a way for them to sandbox me, protecting their servers in case I am hacked? What is the standard solution for a problem like this?

• Anti-virus protection question?

  - by DaBaer

  About 4 years ago, I found Kaspersky and have been using the most current version since. Most people try and argue the use of AVG or Avast to me, and there are some very solid reasons I do not go that route. Over the years, I have found Kasp to become bulkier and bulkier, and have had issues setting it up for friends/family/clients. I am just curios on possible recommendations from other users, with my criteria in mind: What I like about Kasp in the past: The license sold in stores in a 3 pack, is considered a commercial license, and emails from Kasp in response to my questions, make it clear that I can do with the 3 licenses that I want, providing I do not use more than 3 installs per Key. So, allowed me to buy 3, 5, and 7 packs, and resell to users at a cheaper cost than what they would pay if they bought their own license. The ability to easily obtain a currently updated .exe for installation on multiple peoples machines. Power of the scan. Kasp has been a good solution for me (even when using a trial license) on cleaning up machines that were badly infected (in which AVG and AVAST were unable to.) Speed of install/update. After a cleanup of malwarebytes, spybot, mcafee stinger, ccleaner, and combofix, I used to be able to get Kasp Int Security installed and updated in around 5 minutes. The issues that I have with the free AV, is strength of protection. In my opinion for someone who is a 'power use' these are good alternatives, because such a user should be trained or knowledgeable enough to be careful and not get themselves in trouble. Most of the users I assist, are too PC ignorant to know any better, and go hogwild on the web. It has been my experience that the number of people coming back to me with spyware/malware/virus issues since I have converted from AVG to Kasp has been cut down to around 20% of what it used to be 4 or 5 years ago. In a perfect world, I could install and use Kasp Internet Security 2008, and be very happy. But this is not the case anymore. So after this long description of what I used, and have used, does anyone have any good recommendations on AV that isn't going to cost me too much per install?

• Secure linux distro that sends traffic through Tor

  - by gravestone

  I'm looking for a live Linux distro that is secure and preserves my anonymity online. For what I need, Tor seems to do the job – but such software requires configuration that someone who is not knowledgeable in how it works might find difficult. I was looking at 'Lightweight portable security' but it does not specify whether it sends all traffic through Tor. Does anyone know more information about it and/or any other such live Linux distro?

• Member of local Administrators group cannot elevate

  - by fixme

  Hi We have just installed the first Windows 7 (professional) workstation in our domain. Its primary user has been added to the local (computer's) Administrators group (computername\Administrators). Still, whenever elevation is needed, his credentials are not accepted, and he is never allowed to act as an administrator. For example, he cannot write a file to C:\ (not that he needs to, but it illustrates the problem). Putting him in the domain's Administrators group doesn't help either (anyway we'd rather not do that). I suspect that he may be the victim of some policy that controls elevation, but can't seem to find it. Can anyone shed some light?

• Protecting a SVN server

  - by user35072

  For various reasons we are finding it increasingly difficult to work with remote workers. We are a very small developer shop and it's becoming impractical to do manual merges on a daily basis. So we're left with little choice (?) but to consider opening up our SVN servers. I'm looking into the following: Full HTTPS session Running non-80 port Strong password policy Is this enough to prevent someone hacking and stealing data? I will also look into VPN but first would like to understand any alternative solutions.

• Why does Kerberos need Ticket Granting Server?

  - by Narsil

  It's probably something fundamental but I can't find a certain statement. Why can't KDC authenticate then provide the service ticket directly. Is it about security or performance or some other thing? Since users don't log in each time they request a service and assumably they will keep logged in for a long time, AS doesn't seem so busy. Why do they have to be seperated?

• How can I restrict the backuppc client user as much as possible? (rsync)

  - by jxn

  I have backuppc making full backups of servers, but I'd like to be sure that my set up is as paranoid as possible. BackupPC is set up to backup via rsync, and it is set up to use a specific user on each client to be backed up. Because the backuppc client user has to have access to every file on the client machine and the ability to ssh into the machine without an interactive password, I'm a little nervous about securing the clients, and I'd like to know I haven't overlooked any options. Here's what I have in place: in the client user's authorized_keys file, i've included from="IPTOSERVER",command="/usr/bin/rsync" before the user's public key, so that the user can only login coming from the BackupPC server. Next, in the sudoers file, I've added this line: backuppc ALL=NOPASSWD: /usr/bin/rsync to allow root-level permissions only for the rsync command for that user. Are there other user, policy, or ssh restrictions that I can add while still allowing the backup pc client user to rsync all files?

• Is auto-logon on laptop with encrypted hard drive secure?

  - by Tobias Diez

  I have the complete hdd of my laptop encrypted (with the Windows built-in Bitlocker) and thus have to login two times upon booting (Bitlocker and user account). Since I'm the only person using the computer (and knowing the Bitlocker password), I was thinking about automatically login into the user account to make the boot process smoother and quicker. In which cases/scenarios is this a bad idea and the additional login gives a true additionally layer of security?

• How to prevent virtual machines's copy

  - by Florent

  I'll have to deploy virtual machines on demo laptops, which will use Vmware player, but I've got some security concerns, as some data stored in the virtual machines are a bit sensitive. Is there a way to prevent the copy of these virtual machines ? Are the virtual hard drives encrypted, and if not is there a way to encrypt them ? In short, is there a way to lock down everything so that nobody could copy and or use these VMs in another computer ?

• How to open a server port outside of an OpenVPN tunnel with a pf firewall on OSX (BSD)

  - by Timbo

  I have a Mac mini that I use as a media server running XBMC and serves media from my NAS to my stereo and TV (which has been color calibrated with a Spyder3Express, happy). The Mac runs OSX 10.8.2 and the internet connection is tunneled for general privacy over OpenVPN through Tunnelblick. I believe my anonymous VPN provider pushes "redirect_gateway" to OpenVPN/Tunnelblick because when on it effectively tunnels all non-LAN traffic in- and outbound. As an unwanted side effect that also opens the boxes server ports unprotected to the outside world and bypasses my firewall-router (Netgear SRX5308). I have run nmap from outside the LAN on the VPN IP and the server ports on the mini are clearly visible and connectable. The mini has the following ports open: ssh/22, ARD/5900 and 8080+9090 for the XBMC iOS client Constellation. I also have Synology NAS which apart from LAN file serving over AFP and WebDAV only serves up an OpenVPN/1194 and a PPTP/1732 server. When outside of the LAN I connect to this from my laptop over OpenVPN and over PPTP from my iPhone. I only want to connect through AFP/548 from the mini to the NAS. The border firewall (SRX5308) just works excellently, stable and with a very high throughput when streaming from various VOD services. My connection is a 100/10 with a close to theoretical max throughput. The ruleset is as follows Inbound: PPTP/1723 Allow always to 10.0.0.40 (NAS/VPN server) from a restricted IP range >corresponding to possible cell provider range OpenVPN/1194 Allow always to 10.0.0.40 (NAS/VPN server) from any Outbound: Default outbound policy: Allow Always OpenVPN/1194 TCP Allow always from 10.0.0.40 (NAS) to a.b.8.1-a.b.8.254 (VPN provider) OpenVPN/1194 UDP Allow always to 10.0.0.40 (NAS) to a.b.8.1-a.b.8.254 (VPN provider) Block always from NAS to any On the Mini I have disabled the OSX Application Level Firewall because it throws popups which don't remember my choices from one time to another and that's annoying on a media server. Instead I run Little Snitch which controls outgoing connections nicely on an application level. I have configured the excellent OSX builtin firewall pf (from BSD) as follows pf.conf (Apple App firewall tie-ins removed) (# replaced with % to avoid formatting errors) ### macro name for external interface. eth_if = "en0" vpn_if = "tap0" ### wifi_if = "en1" ### %usb_if = "en3" ext_if = $eth_if LAN="{10.0.0.0/24}" ### General housekeeping rules ### ### Drop all blocked packets silently set block-policy drop ### all incoming traffic on external interface is normalized and fragmented ### packets are reassembled. scrub in on $ext_if all fragment reassemble scrub in on $vpn_if all fragment reassemble scrub out all ### exercise antispoofing on the external interface, but add the local ### loopback interface as an exception, to prevent services utilizing the ### local loop from being blocked accidentally. ### set skip on lo0 antispoof for $ext_if inet antispoof for $vpn_if inet ### spoofing protection for all interfaces block in quick from urpf-failed ############################# block all ### Access to the mini server over ssh/22 and remote desktop/5900 from LAN/en0 only pass in on $eth_if proto tcp from $LAN to any port {22, 5900, 8080, 9090} ### Allow all udp and icmp also, necessary for Constellation. Could be tightened. pass on $eth_if proto {udp, icmp} from $LAN to any ### Allow AFP to 10.0.0.40 (NAS) pass out on $eth_if proto tcp from any to 10.0.0.40 port 548 ### Allow OpenVPN tunnel setup over unprotected link (en0) only to VPN provider IPs ### and port ranges pass on $eth_if proto tcp from any to a.b.8.0/24 port 1194:1201 ### OpenVPN Tunnel rules. All traffic allowed out, only in to ports 4100-4110 ### Outgoing pings ok pass in on $vpn_if proto {tcp, udp} from any to any port 4100:4110 pass out on $vpn_if proto {tcp, udp, icmp} from any to any So what are my goals and what does the above setup achieve? (until you tell me otherwise :) 1) Full LAN access to the above ports on the mini/media server (including through my own VPN server) 2) All internet traffic from the mini/media server is anonymized and tunneled over VPN 3) If OpenVPN/Tunnelblick on the mini drops the connection, nothing is leaked both because of pf and the router outgoing ruleset. It can't even do a DNS lookup through the router. So what do I have to hide with all this? Nothing much really, I just got carried away trying to stop port scans through the VPN tunnel :) In any case this setup works perfectly and it is very stable. The Problem at last! I want to run a minecraft server and I installed that on a separate user account on the mini server (user=mc) to keep things partitioned. I don't want this server accessible through the anonymized VPN tunnel because there are lots more port scans and hacking attempts through that than over my regular IP and I don't trust java in general. So I added the following pf rule on the mini: ### Allow Minecraft public through user mc pass in on $eth_if proto {tcp,udp} from any to any port 24983 user mc pass out on $eth_if proto {tcp, udp} from any to any user mc And these additions on the border firewall: Inbound: Allow always TCP/UDP from any to 10.0.0.40 (NAS) Outbound: Allow always TCP port 80 from 10.0.0.40 to any (needed for online account checkups) This works fine but only when the OpenVPN/Tunnelblick tunnel is down. When up no connection is possbile to the minecraft server from outside of LAN. inside LAN is always OK. Everything else functions as intended. I believe the redirect_gateway push is close to the root of the problem, but I want to keep that specific VPN provider because of the fantastic throughput, price and service. The Solution? How can I open up the minecraft server port outside of the tunnel so it's only available over en0 not the VPN tunnel? Should I a static route? But I don't know which IPs will be connecting...stumbles How secure would to estimate this setup to be and do you have other improvements to share? I've searched extensively in the last few days to no avail...If you've read this far I bet you know the answer :)

• Is Flash a secure content delivery technology for password protected digital content?

  - by Merkel Fastia

  We are working on a project that would be a competitor to Yudu for online publishing and what we are debating is whether to use Flash for content security protection as Yudu does. See for example "The Testicle Cookbok" for which a limited (3-frame) preview is available before a password is requested by the Flash application running in the browser. Do you see any problems with this approach or could you recommend an alternative technology for password proected digital content?

• Personally identifiable information (PII) on shared web hosting

  - by S. Cobbs

  Hey folks, I am providing web hosting services (shared and dedicated) and have had one of my shared hosting clients mention needing an SSL cert for their site where they are collecting insurance quotes in a form, including names and social security numbers. My privacy sense is tingling, and I'm pretty sure it's not legal (in the US) to do this on a shared system, but can't find anything to support my thoughts outside of PCI-DSS, but the customer isn't processing payments through the site so I'm not sure if that applies. I'm reading lots of policy documents where people advise to minimize and manage the PII footprint internally, but as the host I don't want to put all of my customer's clients at possible risk. I'm not looking here for legal advice necessarily, but perhaps someone in a similar position to mine can provide some rule of thumb or point me in the right direction.
