  • How to 'Bridge'/'Stream'/'Forward' an Incoming HTTP Connection (Advanced Proxy)

    - by mykl
    Not sure if this is possible..basically a server forwards/bridges an incoming connection Client - Server - Destination Now, rather than a normal proxy script on the server(or a simple redirect), 1) the Destination sees the incoming connection as from the CLIENT (not from the SERVER).. aka masking the server 2) the Server in the middle streams the data back to the client(without downloading it first, then passing it) Anyone know how to do this or something like it in PHP ?

  • Web Service Security java

    - by WhoAmI
    My web service was created some time back using IBM JAX-RPC. As a part of enhancement, I need to provide some security to the existing service. One way is to provide a handler, all the request and response will pass through that handler only. In the request I can implement some authentication rules for each and every application/user accessing it. Other than this, What are the possible ways for securing it? I have heard someting called wsse security for web service. Is it possible to implement it for the JAX-RPC? Or it can be implemented only for JAX-WS? Need some helpful inputs on the wsse security so that i can jump learning it. Other than handler and wsse security, any other possible way to make a service secure? Please help.

  • Date range advanced count calculation in TSQL

    - by cihata87
    I am working on call center project and I have to calculate the call arrivals at the same time between specific time ranges. I have to write a procedure which has parameters StartTime, EndTime and Interval For Example: Start Time: 11:00 End Time: 12:00 Interval: 20 minutes so program should divide the 1-hour time range into 3 parts and each part should count the arrivals which started and finished in this range OR arrivals which started and haven't finished yet Should be like this: 11:00 - 11:20 15 calls at the same time(TimePeaks) 11:20 - 11:40 21 calls ... 11:40 - 12:00 8 calls ... Any suggestions how to calculate them?

  • Advanced Memory Editing/Function Calling

    - by Saustin
    Hi, I've gotten extremely interested into coding trainers (Program that modifies value of a different process) for video games. I've done the simple 'god-mode' and 'unlimited money' things, but I want to do alot more than that. (Simple editing using WriteProcessMemory) There are memory addresses of functions on the internet of the video game I'm working on, and one of functions is like "CreateCar" and I'm wanting to call that function from an external program. My question: How can I call a function from an external process in C/C++, provided the function address, using a process handle or other method. PS: If anyone could link me to tools (I've got debuggers, no need for more..) that help with this sort of thing, that'd be nice.

  • SQL SERVER – Beginning of SQL Server Architecture – Terminology – Guest Post

    - by pinaldave
    SQL Server Architecture is a very deep subject. Covering it in a single post is an almost impossible task. However, this subject is very popular topic among beginners and advanced users.  I have requested my friend Anil Kumar who is expert in SQL Domain to help me write  a simple post about Beginning SQL Server Architecture. As stated earlier this subject is very deep subject and in this first article series he has covered basic terminologies. In future article he will explore the subject further down. Anil Kumar Yadav is Trainer, SQL Domain, Koenig Solutions. Koenig is a premier IT training firm that provides several IT certifications, such as Oracle 11g, Server+, RHCA, SQL Server Training, Prince2 Foundation etc. In this Article we will discuss about MS SQL Server architecture. The major components of SQL Server are: Relational Engine Storage Engine SQL OS Now we will discuss and understand each one of them. 1) Relational Engine: Also called as the query processor, Relational Engine includes the components of SQL Server that determine what your query exactly needs to do and the best way to do it. It manages the execution of queries as it requests data from the storage engine and processes the results returned. Different Tasks of Relational Engine: Query Processing Memory Management Thread and Task Management Buffer Management Distributed Query Processing 2) Storage Engine: Storage Engine is responsible for storage and retrieval of the data on to the storage system (Disk, SAN etc.). to understand more, let’s focus on the following diagram. When we talk about any database in SQL server, there are 2 types of files that are created at the disk level – Data file and Log file. Data file physically stores the data in data pages. Log files that are also known as write ahead logs, are used for storing transactions performed on the database. Let’s understand data file and log file in more details: Data File: Data File stores data in the form of Data Page (8KB) and these data pages are logically organized in extents. Extents: Extents are logical units in the database. They are a combination of 8 data pages i.e. 64 KB forms an extent. Extents can be of two types, Mixed and Uniform. Mixed extents hold different types of pages like index, System, Object data etc. On the other hand, Uniform extents are dedicated to only one type. Pages: As we should know what type of data pages can be stored in SQL Server, below mentioned are some of them: Data Page: It holds the data entered by the user but not the data which is of type text, ntext, nvarchar(max), varchar(max), varbinary(max), image and xml data. Index: It stores the index entries. Text/Image: It stores LOB ( Large Object data) like text, ntext, varchar(max), nvarchar(max),  varbinary(max), image and xml data. GAM & SGAM (Global Allocation Map & Shared Global Allocation Map): They are used for saving information related to the allocation of extents. PFS (Page Free Space): Information related to page allocation and unused space available on pages. IAM (Index Allocation Map): Information pertaining to extents that are used by a table or index per allocation unit. BCM (Bulk Changed Map): Keeps information about the extents changed in a Bulk Operation. DCM (Differential Change Map): This is the information of extents that have modified since the last BACKUP DATABASE statement as per allocation unit. Log File: It also known as write ahead log. It stores modification to the database (DML and DDL). Sufficient information is logged to be able to: Roll back transactions if requested Recover the database in case of failure Write Ahead Logging is used to create log entries Transaction logs are written in chronological order in a circular way Truncation policy for logs is based on the recovery model SQL OS: This lies between the host machine (Windows OS) and SQL Server. All the activities performed on database engine are taken care of by SQL OS. It is a highly configurable operating system with powerful API (application programming interface), enabling automatic locality and advanced parallelism. SQL OS provides various operating system services, such as memory management deals with buffer pool, log buffer and deadlock detection using the blocking and locking structure. Other services include exception handling, hosting for external components like Common Language Runtime, CLR etc. I guess this brief article gives you an idea about the various terminologies used related to SQL Server Architecture. In future articles we will explore them further. Guest Author  The author of the article is Anil Kumar Yadav is Trainer, SQL Domain, Koenig Solutions.

  • How can robots beat CAPTCHAs?

    - by totymedli
    I have a website e-mail form. I use a custom CAPTCHA to prevent spam from robots. Despite this, I still get spam. Why? How do robots beat the CAPTCHA? Do they use some kind of advanced OCR or just get the solution from where it is stored? How can I prevent this? Should I change to another type of CAPTCHA? I am sure the e-mails are coming from the form, because it is sent from my email-sender that serves the form messages. Also the letter style is the same. For the record, I am using PHP + MySQL, but I'm not searching for a solution to this problem. I was interested in the general situation how the robots beat these technologies. I just told this situation as an example, so you can understand better what I'm asking about.

  • Assigning security groups different ranges

    - by Mustafa Ismail Mustafa
    Is it possible to assign a security group in windows 2008 a specific DHCP scope? Meaning, let's say we have 2 groups, employees and managers in the superscope Company. Assuming that each user is distinctly in either group and there are no overlaps, would it be possible to assign members of the security group employees a dhcp address in the range 192.168.1.0/24 and managers 192.168.2.0/24 ? The DHCP server is the same server. This is on Windows SBS 2008 if it makes any difference If it is possible, how do you go about setting it up. TIA

  • Linux EC2 Instance Security Consideration

    - by Amzath
    I am going to host a web site in Amazon EC2 instance which would be a Linux instance. My web application will be developed using PHP, Apache and MySql. As I am new to Linux and Amazon EC2 environment, what are key areas in security should I consider to protect my server? This may be very very generic question as the security itself a vast area. But I need to kick start with most imporant points. That way I would be able to track down all those areas one by one.

  • Autoinstall of Microsoft Security Essentials give random error message

    - by vegarwe
    I'm using wpkg to auto install Microsoft security essentials on WinXP. At the first login after the installer finishes I get an error message as msseces.exe starts. After a reboot the message goes away. The error message indicates a random access restriction. "An error has occured in the program. Try to open it again. If this problem continues, you'll need to reinstall Microsoft Security Essentials from the Microsoft Download Center. Error code: 0x80070005" Firstly: Does anyone know why I get this error message? Second: How do I debug this kind of problems? The event log doesn't seem to contain anything useful. Is there a tool to detect and list denied system calls?

  • Using Active Directory Security Groups as Hierarchical Tags

    - by Nathan Hartley
    Because active directory security groups can... hold objects regardless of OU. be used for reporting, documentation, inventory, etc. be referenced by automated processes (Get-QADGroupMember). be used to apply policy be used by WSUS I would like to use security groups as hierarchical tags, representing various attributes of a computer or user. I am thinking of (computer centric) tags something like these: /tag/vendor/vendorName /tag/system/overallSystemName /tag/application/vendorsApplicationName /tag/dependantOn/computerName /tag/department/departmentName /tag/updates/Group1 Before fumbling through implementing this, I thought I would seek comments from the community. Specifically in the areas: Does this make sense? Would it work? Has anyone else attempted this? Is there a good reference on the matter I should read? How best to implement the hierarchy? Tag_OU\Type_OU\GroupName (limits quantity in OU, uniqueness not guaranteed) Tag_OU\Type_OU\Tag-Type-GroupName (limits quantity in OU, uniqueness guaranteed, verbose) etc ... Thanks in advance!

  • setting nproc in /etc/security/limit.conf prevents ssh login

    - by omry
    I am trying to use /etc/security/limit.conf on Linux (Debian) to limit the number of processes per user. for starters, I tried to limit my own user processes by adding this to /etc/security/limit.conf: omry hard nproc 100 this locked my user out of ssh. I could open new processes (verified with su omry), but could not log into ssh with that user : sshd reported this in it's log: fatal: setreuid 1000: Resource temporarily unavailable also, I am certain my user is not running anything near 100 processes (actually 6). what can be the reason for this?

  • The application attempted to perform an operation not allowed by the security policy

  • trying to copy security groups to a user using dsmod group utility in AD

    - by newbie
    i am trying to create a batch file that asks to enter source samid and destination samid. then using dsquery and dsget find out what security groups source samid is assigned to and assign destination samid to those security groups using dsmod. everything works except the dsmod group command. it doesnt do anything and batch file stops. if i literally put "CN=marketing,OU=test group,DC=abc,DC=com" instead of %%g and "CN=test1,OU=test group,DC=abc,DC=com" instead of %dusercn%, it works fine. can anyone help with this? i have pasted my scrip here. this last small thing is killing me. echo off echo %date% at %time% set /p susername=enter source user name: set /P dusername=enter destination user name: echo %susername% echo %dusername% set dusercn= %dusercn%=dsquery user -samid %dusername% echo %dusercn% for /f "tokens=*" %%g in ('dsquery user -samid %susername% ^|dsget user -memberof') do (dsmod group %%g -addmbr %dusercn%) echo completed pause

  • Healthcare and Distributed Data Don't Mix

    - by [email protected]
    How many times have you heard the story?  Hard disk goes missing, USB thumb drive goes missing, laptop goes missing...Not a week goes by that we don't hear about our data going missing...  Healthcare data is a big one, but we hear about credit card data, pricing info, corporate intellectual property...  When I have spoken at Security and IT conferences part of my message is "Why do you give your users data to lose in the first place?"  I don't suggest they can't have access to it...in fact I work for the company that provides the premiere data security and desktop solutions that DO provide access.  Access isn't the issue.  'Keeping the data' is the issue.We are all human - we all make mistakes... I fault no one for having their car stolen or that they dropped a USB thumb drive. (well, except the thieves - I can certainly find some fault there)  Where I find fault is in policy (or lack thereof sometimes) that allows users to carry around private, and important, data with them.  Mr. Director of IT - It is your fault, not theirs.  Ms. CSO - Look in the mirror.It isn't like one can't find a network to access the data from.  You are on a network right now.  How many Wireless ones (wifi, mifi, cellular...) are there around you, right now?  Allowing employees to remove data from the confines of (wait for it... ) THE DATA CENTER is just plain indefensible when it isn't required.  The argument that the laptop had a password and the hard disk was encrypted is ridiculous.  An encrypted drive tells thieves that before they sell the stolen unit for $75, they should crack the encryption and ascertain what the REAL value of the laptop is... credit card info, Identity info, pricing lists, banking transactions... a veritable treasure trove of info people give away on an 'encrypted disk'.What started this latest rant on lack of data control was an article in Government Health IT that was forwarded to me by Denny Olson, an Oracle Principal Sales Consultant in Minnesota.  The full article is here, but the point was that a couple laptops went missing in a couple different cases, and.. well... no one knows where the data is, and yes - they were loaded with patient info.  What were you thinking?Obviously you can't steal data form a Sun Ray appliance... since it has no data, nor any storage to keep the data on, and Secure Global Desktop allows access from Macs, Linux and Windows client devices...  but in all cases, there is no keeping the data unless you explicitly allow for it in your policy.   Since you can get at the data securely from any network, why would you want to take personal responsibility for it?  Both Sun Rays and Secure Global Desktop are widely used in Healthcare... but clearly not widely enough.We need to do a better job of getting the message out -  Healthcare (or insert your business type here) and distributed data don't mix. Then add Hot Desking and 'follow me printing' and you have something that Clinicians (and CSOs) love.Thanks for putting up my blood pressure, Denny.
