Best Practice for Securing Web Services in the BPEL Workflow

What is the best practice for securing web services which are part of a larger service (a business process) and are defined through BPEL?
They are all deployed on the same oracle application server.
Defining agent for each?
Gateway for all?
BPEL security extension?
The top level service that is defined as business process is secure itself through OWSM and username and passwords, but what is the best practice for security establishment for each low level services?
Regards
Farbod

It doesnt matter whether the service is invoked as part of your larger process or not, if it is performing any business critical operation then it should be secured.
The idea of SOA / designing services is to have the services available so that it can be orchestrated as part of any other business process.
Today you may have secured your parent services and tomorrow you could come up with a new service which may use one of the existing lower level services.
If all the services are in one Application server you can make the configuration/development environment lot easier by securing them using the Gateway.
Typical probelm with any gateway architecture is that the service is available without any security enforcement when accessed directly.
You can enforce rules at your network layer to allow access to the App server only from Gateway.
When you have the liberty to use OWSM or any other WS-Security products, i would stay away from any extensions. Two things to consider
The next BPEL developer in your project may not be aware of Security extensions
Centralizing Security enforcement will make your development and security operations as loosely coupled and addresses scalability.

Best practice for securing confidential legal documents in DMS?

We have a requirement to store confidential legal documents in DMS and are looking at options to secure access to those documents. We are curious to know. What is the best practice? And how are other companies doing it?
TIA,
Margie
Perrigo Co.

Hi,
The standard practice for such scenarios is to use 'authorization' concept.You can give every user to use authorization to create,change or display these confidential documents. In this way, you can control access authorization.SAP DMS system monitors how you work, and prevents you from displaying or changing originals if you do not have the required authorization.
The below link will provide you with an improved understanding of authorization concept and its application in DMS

Best Practice For Secure File Sharing?

I'm a newbie to both OX X Server and File Sharing protocols, so please excuse my ignorance...
My client would like to share folders in the most secure way possible; I was considering that what might be the best way would be for them to VPN into the server and then view the files through the VPN tunnel; my only issue with this is that I have no idea how to open up File Sharing to ONLY allow users who are connecting from the VPN (i.e. from inside of the internal network)... I don't see any options in Server Admin to restrict users in that way....
I'm not afraid of the command line, FYI, I just don't know if this is:
1. Possible!
And 2. The best way to ensure secure AND encrypted file sharing via the server...
Thanks for any suggestions!

my only issue with this is that I have no idea how to open up File Sharing to ONLY allow users who are connecting from the VPN
Simple - don't expose your server to the outside world.
As long as you're running on a NAT network behind some firewall or router that's filtering traffic, no external traffic can get to your server unless you setup port forwarding - this is the method used to run, say, a public web server where you tell the router/firewall to allow incoming traffic on port 80 to get to your server.
If you don't setup any port forwarding, no external traffic can get in.
There are additional steps you can take - such as running the software firewall built into Mac OS X to tell it to only accept network connections from the local network, but that's not necessary in most cases.
And 2. The best way to ensure secure AND encrypted file sharing via the server...
VPN should take care of most of your concerns - at least as far as the file server is concerned. I'd be more worried about what happens to the files once they leave the network - for example have you ensured that the remote user's local system is sufficiently secured so that no one can get the documents off his machine once they're downloaded?

Best practice for secure zone various access

I am setting up a new site with a secure zone.
There will be a secure zone. Once logged in, users will have access to search and browse medical articles/resources
This is how an example may go:
The admin user signs up Doctor XYZ to the secure zone.
The Doctor XYZ is a heart specialist, so he only gets access to web app items that are classified as "heart".
However, he may also be given access to other items, eg: "lung" items.
Or, even all items. It will vary from user to user.
Is there any way to separate areas within the secure zone and give access to those separate areas (without having to give access to individual items - which will be a pain because there will be hundreds of records; and also without having the user log out and log into another secure area)

my only issue with this is that I have no idea how to open up File Sharing to ONLY allow users who are connecting from the VPN

Best Practices for securing VTY lines?

Hi all,
The thread title makes this sound like a big post but it's not.
If my router has say., 193 VTY lines as a maximum, but by default running-config has only a portion of those mentioned, should I set any configs I do on all lines, or just on the lines sh run shows? Example:
sh run on a router I have with default config has: :
line vty 0 4
access-class 23 in
privilege level 15
login local
transport input telnet ssh
line vty 5 15
access-class 23 in
privilege level 15
login local
transport input telnet ssh
Yet, I have the option of configuring up to 193 VTY lines:
Router(config)#line vty ?
<0-193> First Line number
It seems lines 16-193 still exist in memory, so my concern is that they are potentially exposed somehow to exploits or what not. So my practice is to do any configs I do using VTY 0 193 to ensure universal configuration. But, my "enabling" the extra lines, am I using more memory, and, how secure is this against somebody trying to say, connect 193 times to my router simtaneously? Does it increase the likelihood of success on DoS attack for example.

Hi guys, thanks for the replies and excellent information. I'm excited to look at the IOS Hardending doc and the other stuff too.
Just to clarify, I don't actually use the default config, I only pasted it from a new router just to illustrate the default VTY line count.
I never use telnet from inside or outside, anyting snooping a line will pick up the cleartext as ou both know of course. SSH is always version 2 etc.
I was considering doing a console server from the insidde as the only access method - which I do have set up but I have to remote to it It's just that with power outages at times, the console PC won't come back up (no BIOS setting to return to previous state, no WOL solution in place) so now I have both that plus the SSH access. I have an ACL on both the VTY lines themselves as well as a ZBFW ACL governing SSH - perhaps a bit redundant in some ways but oh well if there's a zero-day ou thtere for turning off the zbfw I might still be protected
Regretfully I havne't learned about AAA yet - that I believe is in my CCNA Security book but first I need to get other things learned.
And with regard to logging in general, both enabling the right kind and monitoring it properly, that's a subject I need to work on big time. I still get prot 25 outbound sometimes from a spam bot, but by the time I manually do my sh logging | i :25 I have missed it (due to cyclic logging with a buffer at 102400). Probably this woud be part of that CCNA Security book as well.
So back to the # of VTY lines. I will see what I can do to reduce the line count. I suppose something like "no line vty 16 193" might work, if not it'll take some research.
But if an attacker wants to jam up my vty lines so I can't connect in, once they've fingerprinted the unit a bit to find out that I don't have an IPS running for example, wouldn't it be better that they have to jam up 193 lines simultaneously (with I presume 193 source IPs) instaed of 16? Or am I just theorizing too much here. I'ts not that this matters much, anybody who cares enough to hack this router will get a surprise when they find out there's nothing worth the effort on the other side But this is more so I can be better armed for future deployments. Anyway, I will bookmark the info from this thread and am looking forward to reading it.

Best practices for securely storing environment properties

Hi All,
We have a legacy security module that is included in many
different applications. Historically the settings (such as
database/ldap username and password) was stored directly in the
files that use them. I'm trying to move towards a more centralized
and secure method of storing this information, but need some help.
First of all, i'm struggling a little bit with proper scoping
of these variables. If another application does a cfinclude on one
of the assets in this module, these environment settings must be
visible to the asset, but preferrably not visible to the 'calling'
application.
Second i'm struggling with the proper way to initialize these
settings. If other applications run a cfinclude on these assets,
the application.cfm in the local directory of the script that's
included does not get processed. I'm left with running an include
statement in every file, which i would prefer to avoid if at all
possible.
There are a ton (>50) applications using this code, so i
can't really change the external interface. Should i create a
component that returns the private settings and then set the
'public' settings with Server scope? Right now i'm using
application scope for everything because of a basic
misunderstanding of how the application.cfm's are processed, and
that's a mess.
We're on ColdFusion 7.
Thanks!

Hi,
Thank you for posting in Windows Server Forum.
As per my research, we can create some script for patching the server and you have 2 servers for each role. If this is primary and backup server respectively then you can manage to update each server separately and bypass the traffic to other server. After
completing once for 1 server you can just perform the same step for other server. Because as I know we need to restart the server once for successful patching update to the server.
Hope it helps!
Thanks.

Best practices for securing communication to internet based SCCM clients ?

What type of SSL certs does the community think should be used to secure traffic from internet based SCCM clients ? should 3rd party SSL certs be used ? When doing an inventory for example of the clients configuration in order to run reports
later how the data be protected during transit ?

From a technical perspective, it doesn't matter where the certs come from as there is no difference whatsoever. A cert is a cert is a cert. The certs are *not* what provide the protection, they simply enable the use of SSL to protect the data in transit
and also provide an authentication mechanism.
From a logistics and cost perspective though, there is a huge difference. You may not be aware, but *every* client in IBCM requires its own unique client authentication certificate. This will get very expensive very quickly and is a recurring cost because
certs expire (most commercial cert vendors rarely offer certs valid for more than 3 years). Also, deploying certs from a 3rd party is not a trivial endeavor -- you more less run into chicken and egg issues here. With an internal Microsoft PKI, if designed
properly, there is zero recurring cost and deployment to internal systems is trivial. There is still certainly some cost and overhead involved, but it is dwarfed by that that comes with using with a third party CA for IBCM certs.

Best Practices for Setting up MailBox Quotas in Unity Connection.

Hi all,
I've just completed migrating from Unity 4.0.5 to Unity Connection 8.0.2c and all seems to be working well at the moment. I am looking into setting up quotas for subscriber mailboxes and I would like to find out what are the rules of thumb when assigning disc space to user mailboxes ? and How much disc space does it take for a one minute message ?
Thanks in advance for any inputs/suggestions !!!
D.

D. Tran,
Here are some things to consider:
–Mailbox Quotas
•Specifies a mailbox size in MB for Warning, Send, and Send/Receive Quotas on mailboxes
•Can be applied system-wide and customized on a per-user basis (maximum mailbox size is 2GB)
•Default Warning Quota = 12 MB (25 min of recording with G711)
•Default Send Quota = 13 MB (27 min of recording with G711)
•Default Send/Receive Quota = 14 MB (29 min of recording with G711)
When you use G711, the space requirements for a message are:
•480Kb/min when using G.711
–Message Aging Policy
•If enabled, it applies system-wide but can be disabled on a per-user basis.
•If disabled, no message aging policies are applied and cannot be enabled on a per-user basis.
Should you need to be more aggressive in your Message Aging Policy, you can optionally choose to move saved messages to the Deleted Items folder within a specified timeframe. This is disabled by default.
I typically recommend giving users access to the deleted items (it allows them to access deleted messages for a period of time after they delete them). This is set in the Class of Service here:
–Class of Service > Message Options > Uncheck “Delete Messages Without Saving to Deleted Items Folder”
Hope this helps.

Enterpise Best Practices for iPad

Is anyone aware of any documentation idnetifying best practices for securely deploying iPads in an enterprise environment?

There is some information out there, though not as much as I think we are typically used to for enterprise environments. (It is a consumer device, and Apple is a consumer-driven company, and I don't fault them for that one bit.)
Here is some documentation from Apple:
http://www.apple.com/support/ipad/enterprise/
Also, Jamf Software has some information regarding their Casper suite.
We don't use it yet at my workplace, but I have heard good things about them.

Best Practice for Production IDM setup

Hi, what is the best practice for setting up prodcution IDM:
1. Connect IDM prod to ECC DEV,QA and Prod or
2. Connect IDM prod to ECC prod only and Connect IDM dev to ECC Dev and QA.
Please also specify pros and cons for both options if possible.
Thanks in advance,
Farhan

We run our IDM installation as per your option 2 (Prod and non-prod on separate instances)
We use HCM for the source of truth in production and have a strict policy regarding not allowing non HCM based user accounts. HCM creates the SU01 record and details are downloaded to IDM through the LDAP extract. Access is provision based on Roles attached to the HCM Position in IDM. In Dev/test/uat we create user logins in IDM and push the details out.
Our thinking was that we definitely needed a testing environment for development and patch testing, and it needs to be separate to production. It was also ideal to use this second environment for dev/test/uat since we are in the middle of a major SAP project rollout and are creating hundreds of test and training users with various roles and prefer to keep this out of a production instance.
Lately we also created a sandpit environment since I found that I could not do destructive testing or development in the dev/test/uat instance because we were becoming reliant on this environment being available. Almost a second production instance - since we also set the policy that all changes are made through IDM and no direct SU01 changes are permitted.
Have a close look at your usage requirements before deciding which structure works best for you.

Best practice for integrating a 3 point metro-e in to our network.

Hello,
We have just started to integrate a new 3 point metro-e wan connection to our main school office. We are moving from point to point T-1?s to 10 MB metro-e. At the main office we have a 50 MB going out to 3 other sites at 10 MB each. For two of the remote sites we have purchase new routers ? which should be straight up configurations. We are having an issue connecting the main office with the 3rd site.
At the main office we have a Catalyst 4006 and at the 3rd site we are trying to connect to a catalyst 4503.
I have attached configurations from both the main office and 3rd remote site as well as a basic diagram of how everything physically connects. These configurations are not working ? we feel that it is a gateway type problem ? but have reached no great solutions. We have tried posting to a different forum ? but so far unable to find the a solution that helps.
The problem I am having is on the remote side. I can reach the remote catalyst from the main site, but I cannot reach the devices on the other side of the remote catalyst however the remote catalyst can see devices on it's side as well as devices at the main site.
We have also tried trunking the ports on both sides and using encapsulation dot10q ? but when we do this the 3rd site is able to pick up a DHCP address from the main office ? and we do not feel that is correct. But it works ? is this not causing a large broad cast domain?
If you have any questions or need further configuration data please let me know.
The previous connection was a T1 connection through a 2620 but this is not compatible with metro-e so we are trying to connect directly through the catalysts.
The other two connection points will be connecting through cisco routers that are compatible with metro-e so i don't think I'll have problems with those sites.
Any and all help is greatly welcome ? as this is our 1st metro e project and want to make sure we are following best practices for this type of integration.
Thank you in advance for your help.
Jeff

Jeff, form your config it seems you main site and remote site are not adjacent in eigrp.
Try adding a network statement for the 171.0 link and form a neighbourship between main and remote site for the L3 routing to work.
Upon this you should be able to reach the remote site hosts.
HTH-Cheers,
Swaroop

Best practice for external but secure access to internal data?

We need external customers/vendors/partners to access some of our company data (view/add/edit). It’s not so easy as to segment out those databases/tables/records from other existing (and put separate database(s) in the DMZ where our server is). Our
current solution is to have a 1433 hole from web server into our database server. The user credentials are not in any sort of web.config but rather compiled in our DLLs, and that SQL login has read/write access to a very limited number of databases.
Our security group says this is still not secure, but how else are we to do it? Even if a web service, there still has to be a hole in somewhere. Any standard best practice for this?
Thanks.

Security is mainly about mitigation rather than 100% secure, "We have unknown unknowns". The component needs to talk to SQL Server. You could continue to use http to talk to SQL Server, perhaps even get SOAP Transactions working but personally
I'd have more worries about using such a 'less trodden' path since that is exactly the areas where more security problems are discovered. I don't know about your specific design issues so there might be even more ways to mitigate the risk but in general you're
using a DMZ as a decent way to mitigate risk. I would recommend asking your security team what they'd deem acceptable.
