• Network authentication + roaming home directory - which technology should I look into using?

  - by Brian

  I'm looking into software which provides a user with a single identity across multiple computers. That is, a user should have the same permissions on each computer, and the user should have access to all of his or her files (roaming home directory) on each computer. There seem to be many solutions for this general idea, but I'm trying to determine the best one for me. Here are some details along with requirements: The network of machines are Amazon EC2 instances running Ubuntu. We access the machines with SSH. Some machines on this LAN may have different uses, but I am only discussing machines for a certain use (running a multi-tenancy platform). The system will not necessarily have a constant amount of machines. We may have to permanently or temporarily alter the amount of machines running. This is the the reason why I'm looking into centralized authentication/storage. The implementation of this effect should be a secure one. We're unsure if users will have direct shell access, but their software will potentially be running (under restricted Linux user names, of course) on our systems, which is as good as direct shell access. Let's assume that their software could potentially be malicious for the sake of security. I have heard of several technologies/combinations to achieve my goal, but I'm unsure of the ramifications of each. An older ServerFault post recommended NFS & NIS, though the combination has security problems according to this old article by Symantec. The article suggests moving to NIS+, but, as it is old, this Wikipedia article has cited statements suggesting a trending away from NIS+ by Sun. The recommended replacement is another thing I have heard of... LDAP. It looks like LDAP can be used to save user information in a centralized location on a network. NFS would still need to be used to cover the 'roaming home folder' requirement, but I see references of them being used together. Since the Symantec article pointed out security problems in both NIS and NFS, is there software to replace NFS, or should I heed that article's suggestions for locking it down? I'm tending toward LDAP because another fundamental piece of our architecture, RabbitMQ, has a authentication/authorization plugin for LDAP. RabbitMQ will be accessible in a restricted manner to users on the system, so I would like to tie the security systems together if possible. Kerberos is another secure authentication protocol that I have heard of. I learned a bit about it some years ago in a cryptography class but don't remember much about it. I have seen suggestions online that it can be combined with LDAP in several ways. Is this necessary? What are the security risks of LDAP without Kerberos? I also remember Kerberos being used in another piece of software developed by Carnegie Mellon University... Andrew File System, or AFS. OpenAFS is available for use, though its setup seems a bit complicated. At my university, AFS provides both requirements... I can log in to any machine, and my "AFS folder" is always available (at least when I acquire an AFS token). Along with suggestions for which path I should look into, does anybody have any guides which were particularly helpful? As the bold text pointed out, LDAP looks to be the best choice, but I'm particularly interested in the implementation details (Keberos? NFS?) with respect to security.

• Build Systems for PHP Web Apps

  - by macinjosh

  I want to start automating more of my web development process so I'm looking for a build system. I write mostly PHP apps on Mac OS X and deploy Linux servers over FTP. A lot of my clients have basic hosting providers so shell access to their servers is typically not available, however remote MySQL access is usually present. Here is what I want to do with a build system: When Building: Lint JavaScript Files Validate CSS Files Validate HTML Files Minify and concatenate JS and CSS files Verify PHP Syntax Set Debug/Production flags When Deploying Checkout latest version from SVN Run build process Upload files to server via FTP Run SQL scripts on remote DB I realize this is a lot of work to automate but I think it would be worth it. So what is the best way to start down this path? Is there a system that can handle builds and deploys, or should I search for separate solutions? What systems would you recommend?

• JBoss, exploded jar vs compact jar.

  - by Win Man

  Hi, I am working on Java 1.6, JBoss 5.1, EJB 3, and Hibernate 2. Every time I deploy the ear, if the jar is a compact one (non-exploded), application doesn't work. However when I explode the jar and then add it to the ear, the app works fine. Tried restarting Jboss, doesn't help. The ear refers to numerous external jars; would the order of loading the jars be an issue? How can I make JBoss load external jars followed by the app jars? Thx. WM.

• WCF client encrypt message to JAVA WS using username_token with message protection client policy

  - by Alex

  I am trying to create a WCF client APP that is consuming a JAVA WS that uses username_token with message protection client policy. There is a private key that is installed on the server and a public certificate file was exported from the JKS keystore file. I have installed the public key into certificate store via MMC under Personal certificates. I am trying to create a binding that will encrypt the message and pass the username as part of the payload. I have been researching and trying the different configurations for about a day now. I found a similar situation on the msdn forum: http://social.msdn.microsoft.com/Forums/en/wcf/thread/ce4b1bf5-8357-4e15-beb7-2e71b27d7415 This is the configuration that I am using in my app.config <customBinding> <binding name="certbinding"> <security authenticationMode="UserNameOverTransport"> <secureConversationBootstrap /> </security> <httpsTransport requireClientCertificate="true" /> </binding> </customBinding> <endpoint address="https://localhost:8443/ZZZService?wsdl" binding="customBinding" bindingConfiguration="cbinding" contract="XXX.YYYPortType" name="ServiceEndPointCfg" /> And this is the client code that I am using: EndpointAddress endpointAddress = new EndpointAddress(url + "?wsdl"); P6.WCF.Project.ProjectPortTypeClient proxy = new P6.WCF.Project.ProjectPortTypeClient("ServiceEndPointCfg", endpointAddress); proxy.ClientCredentials.UserName.UserName = UserName; proxy.ClientCredentials.ClientCertificate.SetCertificate(StoreLocation.CurrentUser, StoreName.My, X509FindType.FindByThumbprint, "67 87 ba 28 80 a6 27 f8 01 a6 53 2f 4a 43 3b 47 3e 88 5a c1"); var projects = proxy.ReadProjects(readProjects); This is the .NET CLient error I get: Error Log: Invalid security information. On the Java WS side I trace the log : SEVERE: Encryption is enabled but there is no encrypted key in the request. I traced the SOAP headers and payload and did confirm the encrypted key is not there.

• Can't Deploy or Upload Large SSRS 2008 Report from VS or IE

  - by Bratch

  So far in this project I have two reports in VS2008/BIDS. The first one contains 1 tablix and is about 100k. The second one contains 3 tablixes (tablices?) and is about 257k. I can successfully deploy the smaller report from VS and I can upload it from the Report Manager in IE. I can view/run it from Report Manager and I can get to the Report Server (web service) URL from my browser just fine. Everything is done over HTTPS and there is nothing wrong with the certificates. With the larger report, the error I get in VS is "The operation has timed out" after about 100 seconds. The error when I upload from IE is "The underlying connection was closed: An unexpected error occurred on a send" after about 130 seconds. In the RSReportServer.config file I tried changing Authentication/EnableAuthPersistence from true to false and restarting the service, but still get the error. I have the key "SecureConnectionLevel" set to 2. Changing this to 0 and turning off SSL is not going to be an option. I added a registry key named "MaxRequestBytes" to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\HTTP\Parameters and set it to 5242880 (5MB) and restarted the HTTP and SRS services as suggested in a forum post by Jin Chen of MSFT. I still cannot upload the larger report. This is on MS SQL 2008 and WS 2003. Below is part of a log file entry from ...\Reporting Services\LogFiles when I attempted to upload from IE. library!WindowsService_0!89c!02/10/2010-07:57:57:: i INFO: Call to CleanBatch() ends ui!ReportManager_0-1!438!02/10/2010-07:59:33:: e ERROR: The underlying connection was closed: An unexpected error occurred on a send. ui!ReportManager_0-1!438!02/10/2010-07:59:34:: e ERROR: HTTP status code -- 500 -------Details-------- System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. --- System.IO.IOException: Unable to write data to the transport connection: An established connection was aborted by the software in your host machine. --- System.Net.Sockets.SocketException: An established connection was aborted by the software in your host machine at System.Net.Sockets.Socket.MultipleSend(BufferOffsetSize[] buffers, SocketFlags socketFlags) at System.Net.Sockets.NetworkStream.MultipleWrite(BufferOffsetSize[] buffers) --- End of inner exception stack trace --- ...

• VLC (Server) re-stream Security Camera Feed

  - by Aaron

  I purchased a Swann Home Security DVR system and was hoping for some help on how to duplicate the streaming video on my server. In order to get their web view (streaming video in the browser) to work, I had to install the following plugins: HiDvrPlugin.dmg for mac. Hidvrocx.cab for Windows. I was originally thinking it was a sign of some form of DRM? Maybe. Maybe not. HTML wise, the following code is in the source of the safari version of the web view: <embed pluginspage="SurveilClient.dmg" width="10px" height="10px" type="application/x-scplugin" id="MacDiv" style="height: 592px; width: 720px; left: 278px; top: 61px; "> It seems to be the main display area. Using wireshark, I am able to see that the video stream is on port 9000. However, I have no idea what type of stream it is. I've tried opening it in VLC with no such luck. http://dvr_ip:9000 tcp://dvr_ip:9000 My hope was to do the following to redistribute the feed vlc dvr_ip:9000 --sout h264-version-on-localhost:3000 TLDR; Trying to re-distribute a stream from a security camera (can't tell the format) using vlc (re-distribute via h.264 / HTML5). Not sure how to accomplish this. Is it possible that the software has some type of DRM that only the plugins can decode?

• Windows Server 2003 R2 Terminal Server : Internet Explorer Enhanced Security won't disable for Users

  - by Tubs

  The Internet Explorer Enhanced Security (IEES) won't disable using the normal method of disabling it from the Add/Remove Programs/Windows components. This came to light immediately after testing. IEES was disabled after Terminal Services were installed for admin and users, and after IE8 was installed. My initial thoughts were that there was some clash between IE8 and IE6 (which is the default on 2003 R2), so I uninstalled IE8 and reverted back to IE6. The same symptoms were displayed, when a normal user logged on Internet Explorer Enhnaced Security was enforced. I then thought it could be a problem that Terminal Server wasn't recognising the removal as IEES was on when initially installed. I uninistalled the Terminal Server Componants using the server roles, and then reactivated and deavtived IEES. Windows Server 2003 R2 allows a limited number of users to connect to RDP by default, so I logged on as a normal user, and IEES was disabled. I then reinstalled Terminal Server, and logged on as a normal user. IEES was back enabled. Why is this?

• Cisco ASA Act as a Hardware Security Module?

  - by Derek

  Hello, We have a partner that is requiring us to get a HSM for a web application that we host for them. This is something new for us, we've always installed our SSL certificates on our web servers and never needed a hardware device. We currently have 2 Cisco ASA 5510 firewalls in an active/standby configuration. Both ASAs have a ASA-SSM-10 security module installed in them. The web application is a standard HTTPS webpage with no authentication required. I was wondering if we could use our Cisco ASAs to meet this requirement or if we'll have to buy another device. I was doing some searching and read about Cisco's clientless webvpn feature. It sounds like it might work, but I'm not sure. We basically want the ASA to handle the SSL and proxy the connection to our web servers. We do not want to prompt for a username or password to connect or show any portals, just display the web page. If the ASA cannot do this, does any one have any recommendations for network attached hardware security modules? We are using VMware vCenter, so we'd rather have an external device attached to the network, rather than buying HSM cards for every ESXi host. Thanks, Derek

• Cannot Change "Log on through Terminal Services" in Local Security Policy XP from Server 2008 GP

  - by Campo

  This is a mixed AD environment, Server 2003 R2 and 2008 R2 I have a 2003 AD R2 and a 2008 R2 AD. GPO is usually managed from the 2008 R2 machine. I have a RD Gateway on another server as well. I setup the CAP and RAP to allow a normal user to log on to the departments workstation. I also adjusted the GPO for that OU to allow Log on trhough Remote Desktop Gateway for the user group. This worked on my windows 7 workstation. But unfortunately the policy is a different name in XP "allow log on through Terminal Services" I can get through right into the machine but when the log on actually happens to the local machine i get the "Cannot log on interactively" error. This is set in (for the local machine) Secpol.msc Local Security Policy "user rights assignment" but is controlled by the GPO in Computer Configuration Policies Security Settings Local Policies "User Rights Assignment" Do I simply need to adjust the same setting on the same GPO but with a server 2003 GP editor? Feel like that could cause issues... Looking for some direction. Or if anyone has run into this issue yet. UPDATE Should this work? support.microsoft.com/kb/186529 Still seems like I will have the issue as the actual GP settings for Log on through Terminal Services is still different between Server 2008 R2 and 2003 R2.... Another Thought: Should I delete the GPO made for the department and remake it with the 2003 R2 server? I have no 2008 specific settings as the whole department runs XP other than myself. If that's a solution I will move my computer out of the department as a solution... Thoughts?

• make an http post from server using user credentials - integrated security

  - by opensas

  I'm trying to make a post, from an asp classic server side page, using the user credentials... I'm using msxml2.ServerXMLHTTP to programatically make the post I've tried with several configurations in the IIS 5.1 site, but there's no way I can make IIS run with a specified account... I made a little asp page that runs whoami to verify what account the iis process i using... with IIS 5.1, using integrated security the process uses: my_machine\IWAM_my_machine I disable integrated security, and leave a domain account as anonymous access, and I get the same (¿?) to test the user I do the following private function whoami() dim shell, cmd set shell = createObject("wscript.shell") set cmd = shell.exec( server.mapPath( "whoami.exe" ) ) whoami = cmd.stdOut.readAll() set shell = nothing: set cmd = nothing end function is it because I'm issuing a shell command? I'd like to make http post calls, to another site that works with integrated security... So I need some way to pass the credentials, or at least to run with a specified account, and then configure the remote site to thrust that account... I thought that just setting the site to work with integrated security would be enough... How can I achieve such a thing? ps: with IIS6,happens the same but if I change the pool canfiguration I get the following info from whoami NT AUTHORITY\NETWORK SERVICE NT AUTHORITY\LOCAL SERVICE NT AUTHORITY\SYSTEM if I set a domain account, I get a "service unavailable" message... edit: found this http://www.microsoft.com/technet/prodtechnol/WindowsServer2003/Library/IIS/275269ee-1b9f-4869-8d72-c9006b5bd659.mspx?mfr=true it says what I supossed, "If an authenticated user makes a request, the thread token is based on the authenticated account of the user", but somehow I doesn't seem to work like that... what could I possibly be missing? edit: well the whoami thing is obviously fooling me, I tried with the following function private function whoami_db( serverName, dbName ) dim conn, data set conn = server.createObject("adodb.connection") conn.open "Provider=SQLOLEDB.1;Integrated Security=SSPI;" & _ "Initial Catalog=" & dbName & ";Data Source=" & serverName set data = conn.execute( "select suser_sname() as user_name" ) whoami_db = data("user_name") data.close: conn.close set data = nothing: set conn = nothing end function and everything seemed to be working fine... but how can I make msxml2.ServerXMLHTTP work with the user credentials???

• Error processing response in .net web service with WSE3 mutualCertificate10Security Assertion

  - by Maeloc

  I am securing a .net web service (framework 2.0) with WSE3 mutualCertificate10Security Assertion. When request are valid all is fine and the response is wellformed, but when the request is invalid (cause a invalid signature, failed check, or soapexception thrown), the web server isn't able to process the response to send to the client. The error in application event log is: An error occured processing an outgoing fault response. Details of the error causing the processing failure: System.InvalidOperationException: Send security filter on the server could not retrieve the operation protection requirements from the operation state. en Microsoft.Web.Services3.Security.SecureConversationServiceSendSecurityFilter.SecureMessage(SoapEnvelope envelope, Security security) en Microsoft.Web.Services3.Security.SendSecurityFilter.ProcessMessage(SoapEnvelope envelope) en Microsoft.Web.Services3.Pipeline.ProcessOutputMessage(SoapEnvelope envelope) en Microsoft.Web.Services3.WseProtocol.GetFilteredResponseEnvelope(SoapEnvelope outputEnvelope) All certificate permissions are OK (when request is OK the web service is able to sign the response).

• How to deploy a visual studio custom tool?

  Hello. I have a my own custom tool for Visual Studio 2008 SP1. It consists of 5 assemblies: 3 assemblies with code that used heavily in my other projects, 1 assembly-wrapper above VS2008 SDK and assembly with the tool. If I'd debug my tool from visual studio, using "Run external program" option with command line "C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe" and arguments "/ranu /rootsuffix Exp" all work perfectly. After that I trying to deploy it to my working VS copy, not to experimental hive doing: gacutil /i Asm1.dll for all my assemblies and doing RegAsm Asm1.dll only for assembly with custom tool.

• Creating security permissions for a non-domain-member user in Windows Server 2008

  - by Overhed

  Hello everyone, I apologize in advance for incorrect use of terminology, as I'm not an IT person by trade. I'm doing some remote work via a VPN for a client and I need to add some DCOM Service security permissions for my remote user. Even though I'm on the VPN, the request for access to the DCOM service is using my PCs native user (and since I'm running Vista Home Premium it looks something like: PC-NAME\Username). The request for access comes back with access denied and I can not add this user to the security permissions as it "is not from a domain listed in the Select Location dialog box, and is therefore not valid". I'm pretty stuck and have no clue what kind of steps I need to do here. Any help would be appreciated, thanks in advance. EDIT: I have no control over what credentials are being passed in to the server by my computer. This scenario is occurring in an installation wizard that has a section which requests you point it to the machine running the "server" version of the software I'm installing (it then tries to invoke the relevant COM service, but my user does not have "Remove Activation Permissions" on that service, so I get request denied).

• SQL SERVER – Difference Between GRANT and WITH GRANT

  - by pinaldave

  This was very interesting question recently asked me to during my session at TechMela Nepal. The question is what is the difference between GRANT and WITH GRANT when giving permissions to user. Let us first see syntax for the same. GRANT: USE master; GRANT VIEW ANY DATABASE TO username; GO WITH GRANT: USE master; GRANT VIEW ANY DATABASE TO username WITH GRANT OPTION; GO The difference between both of this option is very simple. In case of only GRANT – username can not grant the same permission to other users. In case, of the option of WITH GRANT – username will be able to give the permission it has received to other users. This is very basic definition of the subject. I would like to request my readers to come up with working script to prove this scenario. If can submit your script to me by email (pinal ‘at’ sqlauthority.com) or in comment field.

• Letöltheto az Oracle Database Firewall 5.0

  - by Lajos Sárecz

  2010 május 20-án jelentettük be, hogy megvettük az adatbázis tuzfal megoldást fejleszto Secerno céget. Azóta viszonylag keveset lehetett hallani errol a termékrol, idehaza egyedül az oszi ITBN konferencián tartott róla eloadást Stuart Sharp szuk fél órában. Ráadásul a felvásárlás óta a terméket sem lehetett megvásárolni, hiszen a merge után folyó fejlesztések még nem voltak készen. Január 11. óta azonban letötlheto az Oracle Database Firewall 5.0 telepítoje az Oracle edelivery oldaláról az Oracle Database Product Pack-en belül Linux x86 platformra. A Database Firewall az adatbázis védelem elso vonalának tekintheto. Valós idoben monitorozza az adatbázis aktivitását a hálózaton. SQL nyelvi elemzojével rendkívül pontosan képes detektálni a külso és belso támadásokat, a jogosultatlanul, támadó szándékkal végrehajtott tranzakciókat. Az SQL nyelvi elemzojének kifinomultsága lehetové teszi a szurés közel 100%-os pontosságát és megbízhatóságát, ami azért rendkívül fontos, mert nem elég minden támadó tranzakciót kiszurni, de fontos hogy a normál üzletmenetnek megfelelo tranzakciók közül egyet se szurjön, hiszen az is komoly üzleti károkat okozhat. Az adatbázis tuzfalról több részletet tudhat meg mindenki, aki regisztrál és ellátogat a január 27-i Oracle Security Summit rendezvényünkre, ahol a tervek szerint ismét Stuart Sharp tart majd eloadást, viszont ezúttal 1 órában sokkal több részletet tud megosztani a magyar ügyfelekkel és partnerekkel. A Database Firewall eloadást megelozoen egyébként én tartok egy kb. félórás áttekintést az Oracle Database biztonsági megoldásairól.

• Booby Traps and Locked-in Kids: An Interview with a Safecracker

  - by Jason Fitzpatrick

  While most of our articles focus on security of the digital sort, this interview with a professional safecracker is an interesting look the physical side of securing your goods. As part of their Interviews with People Who Have Interesting or Unusual Jobs series over at McSweeney’s, they interviewed Ken Doyle, a professional a locksmithing and safecracking veteran with 30 years of industry experience. The interview is both entertaining and an interesting read. One of the more unusual aspects of safecracking he highlights: Q: Do you ever look inside? A: I NEVER look. It’s none of my business. Involving yourself in people’s private affairs can lead to being subpoenaed in a lawsuit or criminal trial. Besides, I’d prefer not knowing about a client’s drug stash, personal porn, or belly button lint collection. When I’m done I gather my tools and walk to the truck to write my invoice. Sometimes I’m out of the room before they open it. I don’t want to be nearby if there is a booby trap. Q: Why would there be a booby trap? A: The safe owner intentionally uses trip mechanisms, explosives or tear gas devices to “deter” unauthorized entry into his safe. It’s pretty stupid because I have yet to see any signs warning a would-be culprit about the danger.

• Is knowledge of hacking mechanisms required for an MMO?

  - by Gabe

  Say I was planning on, in the future (not now! There is alot I need to learn first) looking to participating in a group project that was going to make a massively multiplayer online game (mmo), and my job would be the networking portion. I'm not that familiar with network programming (I've read a very basic book on PHP, MYSQL and I messed around a bit with WAMP). In the course of my studying of PHP and MYSQL, should I look into hacking? Hacking as in port scanning, router hacking, etc. In MMOs people are always trying to cheat, bots and such, but the worst scenario would be having someone hack the databases. This is just my conception of this, I really don't know. I do however understand networking fairly well, like subnetting/ports/IP's (local/global)/etc. In your professional opinion, (If you understand the topic, enlighten me) Should I learn about these things in order to counter the possibility of this happening? Also, out of the things I mentioned (port scanning, router hacking) Is there anything else that pertains to hacking that I should look into? I'm not too familiar with the malicious/Security aspects of Networking. And a note: I'm not some kid trying to learn how to hack. I just want to learn as much as possible before I go to college, and I really need to know if I need to study this or not.

• Implications on automatically "open" third party domain aliasing to one of my subdomains

  - by Giovanni

  I have a domain, let's call it www.mydomain.com where I have a portal with an active community of users. In this portal users cooperate in a wiki way to build some "kind of software". These software applications can then be run by accessing "public.mydomain.com/softwarename" I then want to let my users run these applications from their own subdomains. I know I can do that by automatically modifying the.htaccess file. This is not a problem. I want to let these users create dns aliases to let them access one specific subdomain. So if a user "pippo" that owns "www.pippo.com" wants to run software HelloWorld from his own subdomains he has to: Register to my site Create his own subdomain on his own site, run.pippo.com From his DNS control panel, he creates a CNAME record "run.pippo.com" pointing to "public.mydomain.com" He types in a browser http://run.pippo.com/HelloWorld When the software(that is physically run on my server) is called, first it checks that the originating domain is a trusted one. I don't do any other kind of check that restricts software execution. From a SEO perspective, I care about Google indexing of www.mydomain.com but I don't care about indexing of public.mydomain.com What are the possible security implications of doing this for my site? Is there a better way to do this or software that already does this that I can use?

• An adequate message authentication code for REST

  - by Andras Zoltan

  My REST service currently uses SCRAM authentication to issue tokens for callers and users. We have the ability to revoke caller privileges and ban IPs, as well as impose quotas to any type of request. One thing that I haven't implemented, however, is MAC for requests. As I've thought about it more, for some requests I think this is needed, because otherwise tokens can be stolen and before we identify this and deactivate the associated caller account, some damage could be done to our user accounts. In many systems the MAC is generated from the body or query string of the request, however this is difficult to implement as I'm using the ASP.Net Web API and don't want to read the body twice. Equally importantly I want to keep it simple for callers to access the service. So what I'm thinking is to have a MAC calculated on: the url, possibly minus query string the verb the request ip (potentially is a barrier on some mobile devices though) utc date and time when the client issues the request. For the last one I would have the client send that string in a request header, of course - and I can use it to decide whether the request is 'fresh' enough. My thinking is that whilst this doesn't prevent message body tampering it does prevent using a model request to use as a template for different requests later on by a malicious third party. I believe only the most aggressive man in the middle attack would be able to subvert this, and I don't think our services offer any information or ability that is valuable enough to warrant that. The services will use SSL as well, for sensitive stuff. And if I do this, then I'll be using HMAC-SHA-256 and issuing private keys for HMAC appropriately. Does this sound enough? Have I missed anything? I don't think I'm a beginner when it comes to security, but when working on it I always. am shrouded in doubt, so I appreciate having this community to call upon!

• Trigger IP ban based on request of given file?

  - by Mike Atlas

  I run a website where "x.php" was known to have vulnerabilities. The vulnerability has been fixed and I don't have "x.php" on my site anymore. As such with major public vulnerabilities, it seems script kiddies around are running tools that hitting my site looking for "x.php" in the entire structure of the site - constantly, 24/7. This is wasted bandwidth, traffic and load that I don't really need. Is there a way to trigger a time-based (or permanent) ban to an IP address that tries to access "x.php" anywhere on my site? Perhaps I need a custom 404 PHP page that captures the fact that the request was for "x.php" and then that triggers the ban? How can I do that? Thanks! EDIT: I should add that part of hardening my site, I've started using ZBBlock: This php security script is designed to detect certain behaviors detrimental to websites, or known bad addresses attempting to access your site. It then will send the bad robot (usually) or hacker an authentic 403 FORBIDDEN page with a description of what the problem was. If the attacker persists, then they will be served up a permanently reccurring 503 OVERLOAD message with a 24 hour timeout. But ZBBlock doesn't do quite exactly what I want to do, it does help with other spam/script/hack blocking.
