A Web service is a method of communication between two electronic devices over a network. It is a software function provided at a network address over the Web with the service always on as in the concept of utility computing. A web service has an interface described in Web Services Description Language (WSDL). Other systems interact with the Web service in a manner prescribed by its description using SOAP (Simple Object Access Protocol) messages. There are two major classes of Web services: REST-compliant web services, and Arbitrary web services.

Despite its humble beginnings, phishing has come a long way since those first crudely constructed emails. Today, phishing sites can appear and disappear in the length of a coffee break, and it takes more than a little know-how to keep your clients secure.

I am part of a development for a SOAP web services client on WCF/.NET. After a session of sending request, team for server side left feedback "extend someAction from schema i am mentioning below", and mentioned an URL. In this context, what does it mean to extend from schema?

I have a client who's server is being the subject of repeated intrusion attempts over the last 8 days.  All the source IP's whois back to Amazon Web Services.

Do Amazon follow these up with the user of the IP or do they pursue it in any way?  The attacks are getting more frequent.

Hello,

I can't import my module Activedirectory with this command: import-module activedirectory.
I can't import remotely or on the main DC.

Error: “WARNING: Error initializing default drive: ‘Unable to find a default server with Active Directory Web Services running”

In event viewer I have only this warning: 
Active Directory Web Services could not find a server certificate with the specified certificate name. A certificate is required to use SSL/TLS connections. To use SSL/TLS connections verify that a valid server authentication certificate from a trusted Certificate Authority (CA) is installed on the machine.

Certificate name: srv-dc1.contoso.com

Open in new window


And at every restart I have this error: 

ADWS Error:1202
This computer is now hosting the specified directory instance, but Active Directory Web Services could not service it. Active Directory Web Services will retry this operation periodically.

Directory instance: GC
Directory instance LDAP port: 3268
Directory instance SSL port: 3269

Open in new window


I have 3 DC (3 GC).

I tried everything... Even with "new-psdrive"... Not working. Put the service ADWS on delayed launch... Not working.
Plus:

srv-dc1 = Windows server  2008 Datacenter SP2 (type GC - 2008 r2) with ADWS service.
srv-dc2 = Windows server 2008 standard  (type GC -2k8) without ADWS service.
srv-dc3 = Windows server 2008 standard  (type GC -2k8) without ADWS service.

Before last restart of dc1, everything working well. And now...
And I uninstalled every update installed after restart.
0 port are blocked with firewall.
I can telnet on 9389 on dc1.

Thanks in advance for your help.

Hi Experts,

I did a Nessus scan and received a high vulnerability finding and have a few questions.

This result was from scanning our domain controller(wind 2012 R2).

First how did a certificate get generated when we do not use IIS on this DC? as i do not understand why a certificate would need to be generated on the DC or how it would be? We do not have a CA.



SSL Certificate Cannot Be Trusted

Description

The server's X.509 certificate cannot be trusted. This situation can occur in three different ways, in which the chain of trust can be broken, as stated below :

 - First, the top of the certificate chain sent by the server might not be descended from a known public certificate authority. This can occur either when the top of the chain is an unrecognized, self-signed certificate, or when intermediate certificates are missing that would connect the top of the certificate chain to a known public certificate authority.

 - Second, the certificate chain may contain a certificate that is not valid at the time of the scan. This can occur either when the scan occurs before one of the certificate's 'notBefore' dates, or after one of the certificate's 'notAfter' dates.

 - Third, the certificate chain may contain a signature that either didn't match the certificate's information or could not be verified. Bad signatures can be fixed by getting the certificate with the bad signature to be re-signed by its issuer. Signatures that could not be verified are the…

Hello,

I am using self written Java programmes at home that consume SOAP web services from my rc plane club. So far everything works good, But sometimes the SOAP web services that I use are not available due to maintnance or problems at the club's server. I want to monitor the availability of the SOAP services and persist the status. When I use the SOAP services the programme shall first check the availability from the monitor and if the status is 'available' perform the desired request or else queue the request until the service becomes available again.

Before I start to re-invent the wheel and write my own monitor I wanted to know if there are already tools that can accomplish this task, which can be easily embedded or used in Java before a request.

Best regards,
CB

The code below is executed when a user clicks a button.
It asks the user for a username/password and tries to upload a file to a webservice.
When the username/password combination is correct, everything works fine. But when the user types an incorrect username/password combination, this functions crashes. ( which is normal, because authentication failed...) .
After such a crash, the code no longer works, even after rerunning the same procedure this time with the correct username/password combination.

The only solution I found is to restart the whole application... There has to be a better way?
Does the HTTPRIO object cache my incorrect username/password? Or .... ? 



RIO := THTTPRIO.Create(nil);
RIO.HTTPWebNode.UserName :=Username;
RIO.HTTPWebNode.Password :=PassWord;
webserver := GetCRS( True, '' , RIO );

 // get file to upload and encode it in base64
 myFileToUpload := TByteDynArray( TEncoding.UTF8.GetBytes( xml.XML.Text ) );

// create upload file request object
myUploadFileRequest := UploadFileRequest.Create;
myUploadFileRequest.UploadFile := PayLoadType( myFileToUpload );

// upload file to server
 myUploadFileResponse := webserver.uploadFile_A2A( myUploadFileRequest ); --> Crash

We have a local oracle database 12c.

Another remote system (mysql/java) needs to post a record of data each time a transaction is executed by a user to our local database.

The way it will work is the remote system will call a web service in local database (https) and submits data using CSV format.

Can CSV format support web services and one to many table relationships?

My thinking is that it is fixed-size format and difficult to parse of you have one customre order with multiple line items or none.

Most of the web service I developed were using XML format before.

Hi all,

We use our internal CA using a SHA1 to create certificates for internal web services. We are now tasked with upgrading this to SHA2. My colleague has suggested we renew all SHA1 certificates so that nothing is set to expire within the next 12 months. We will then look to upgrade the rootCA but im concerned that once we do that all the web certificates will need to be upgraded?

Can someone clarify what happens when the ROOTCA is upgraded to SHA2?

It will be difficult to know whether all web services are SHA2 compatible, is there a way to create a separate SHA2 ROOT CA?

websites provide android app fetching from rest api.
websites provide  rest api using c# with just one controller in project and sql server 2016 sending/receiving data for one table.
So these are not compact,efficient for complete project with multiple tables.
I am very curious to have modular code for all these concepts.

Hi Experts,

We are setting up a new automatic deployment environment.
After the process runs and everything gets deployed, we need to check
the health status of a list of windows and web services whose names we will have in some table or XML file.
For ex. there are 50 windows services say service1 to service50 in the xml for windows services.
We need to find the status of all those...and also names of those which are there in xml but did not get installed or deployed by automation process.(delta of services present in xml and not under services.msc).
Similary we need to test all web services listed in xml.
Please help with suggestions and sample code or articles.

Thanks,
