  • Protecting Consolidated Data on Engineered Systems

    - by Steve Enevold
    In this time of reduced budgets and cost cutting measures in Federal, State and Local governments, the requirement to provide services continues to grow. Many agencies are looking at consolidating their infrastructure to reduce cost and meet budget goals. Oracle's engineered systems are ideal platforms for accomplishing these goals. These systems provide unparalleled performance that is ideal for running applications and databases that traditionally run on separate dedicated environments. However, putting multiple critical applications and databases in a single architecture makes security more critical. You are putting a concentrated set of sensitive data on a single system, making it a more tempting target.  The environments were previously separated by iron so now you need to provide assurance that one group, department, or application's information is not visible to other personnel or applications resident in the Exadata system. Administration of the environments requires formal separation of duties so an administrator of one application environment cannot view or negatively impact others. Also, these systems need to be in protected environments just like other critical production servers. They should be in a data center protected by physical controls, network firewalls, intrusion detection and prevention, etc Exadata also provides unique security benefits, including a reducing attack surface by minimizing packages and services to only those required. In addition to reducing the possible system areas someone may attempt to infiltrate, Exadata has the following features: 1.    Infiniband, which functions as a secure private backplane 2.    IPTables  to perform stateful packet inspection for all nodes               Cellwall implements firewall services on each cell using IPTables 3.    Hardware accelerated encryption for data at rest on storage cells Oracle is uniquely positioned to provide the security necessary for implementing Exadata because security has been a core focus since the company's beginning. In addition to the security capabilities inherent in Exadata, Oracle security products are all certified to run in an Exadata environment. Database Vault Oracle Database Vault helps organizations increase the security of existing applications and address regulatory mandates that call for separation-of-duties, least privilege and other preventive controls to ensure data integrity and data privacy. Oracle Database Vault proactively protects application data stored in the Oracle database from being accessed by privileged database users. A unique feature of Database Vault is the ability to segregate administrative tasks including when a command can be executed, or that the DBA can manage the health of the database and objects, but may not see the data Advanced Security  helps organizations comply with privacy and regulatory mandates by transparently encrypting all application data or specific sensitive columns, such as credit cards, social security numbers, or personally identifiable information (PII). By encrypting data at rest and whenever it leaves the database over the network or via backups, Oracle Advanced Security provides the most cost-effective solution for comprehensive data protection. Label Security  is a powerful and easy-to-use tool for classifying data and mediating access to data based on its classification. Designed to meet public-sector requirements for multi-level security and mandatory access control, Oracle Label Security provides a flexible framework that both government and commercial entities worldwide can use to manage access to data on a "need to know" basis in order to protect data privacy and achieve regulatory compliance  Data Masking reduces the threat of someone in the development org taking data that has been copied from production to the development environment for testing, upgrades, etc by irreversibly replacing the original sensitive data with fictitious data so that production data can be shared safely with IT developers or offshore business partners  Audit Vault and Database Firewall Oracle Audit Vault and Database Firewall serves as a critical detective and preventive control across multiple operating systems and database platforms to protect against the abuse of legitimate access to databases responsible for almost all data breaches and cyber attacks.  Consolidation, cost-savings, and performance can now be achieved without sacrificing security. The combination of built in protection and Oracle’s industry-leading data protection solutions make Exadata an ideal platform for Federal, State, and local governments and agencies.

  • Configure Iptables to allow a PHP-app accessing a port-nr

    - by Camran
    I have a php-application which connects to another app called Solr (database search engine). I can via this php app add/remove documents (records) from the Solr index. However, the Solr security is low, and anybody with the right port nr can access Solr and remove documents (records). I wonder, is it possible to ONLY allow my own php-app to have access to Solr somehow? Prefferably via Iptables. I am thinking I can only allow my own servers IP to that port, and it would solve my problem, because PHP is a server-side code. But I am not sure. About the Php-app: The website is a classifieds website, and when users wants to add or remove classifieds, they do so through a php app, which is this one. The app has a function which connects to solr and updates the database (index). I appreciate detailed answers... Thanks

  • Appropriate level of granularity for component-based architecture

    - by Jon Purdy
    I'm working on a game with a component-based architecture. An Entity owns a set of Component instances, each of which has a set of Slot instances with which to store, send, and receive values. Factory functions such as Player produce entities with the required components and slot connections. I'm trying to determine the best level of granularity for components. For example, right now Position, Velocity, and Acceleration are all separate components, connected in series. Velocity and Acceleration could easily be rewritten into a uniform Delta component, or Position, Velocity, and Acceleration could be combined alongside such components as Friction and Gravity into a monolithic Physics component. Should a component have the smallest responsibility possible (at the cost of lots of interconnectivity) or should related components be combined into monolithic ones (at the cost of flexibility)? I'm leaning toward the former, but I could use a second opinion.

  • Physically moving a hard drive from older iMac (c2d) to new iMac (i7) ?

    - by Inshim
    Instead of my usual habit of using superduper to mirror my drive to a new computer, I just physically moved the hard drive from an older iMac to a new one. But... it now doesn't boot, getting stuck at the apple logo screen. Since the hard drive that came with the new iMac works well, and my old drive works well when I return it to the older iMac, I conclude that there is some problem at the system/kernel level due to the different hardware. In the past I did similar things (e.g. starting a C2D machine from a Core Duo in target disk mode), so perhaps the change in architecture to the i5/i7 is too problematic? The main point: do you know of any way to get the system to rebuild for itself the proper versions of the system components when booting? Are there certain directories that I can safely delete to make that happen? Thanks

  • What are the safety benefits of a type system?

    - by vandros526
    In Javascript: The Good Parts by Douglas Crockford, he mentions in his inheritance chapter, "The other benefit of classical inheritance is that it includes the specification of a system of types. This mostly frees the programmer from having to write explicit casting operations, which is a very good thing because when casting, the safety benefits of a type system are lost." So first of all, what actually is safety? protection against data corruption, or hackers, or system malfunctions, etc? What are the safety benefits of a type system? What makes a type system different that allows it to provide these safety benefits?

  • What is the correct term for the number of bits used by an operating system

    - by benc
    Recently, some discussions came up about 32 bit vs. 64 bit implementations of operating systems. While I was composing a message about this topic, I realized that I did not know if there was a correct term for the number of bits supported by an operating system. For example, various versions of Solaris and Linux have 32bit and 64bit releases. Is the distinction "architecture"? In my experience, that has referred to chip types (Intel vs. PPC). Is it a "release"? Typically, I think of a release as a version number a consistent feature set, that might run on different architectures. Maybe it is just "architecture", after all, even though a chip family might have used several different bit sizes over time, the chips themselves are different when you jump from 32bit to 64bit.

  • After upgrade: what's this envelope systray icon, and how do I get rid of it?

    - by David
    I've just upgraded from 13.04 to 13.10 and everything seems to be running fine. I have a couple new icons in my systray, though, and one of them -- the envelope icon -- is a mystery to me: It looks like a chat notifier (clicking it gives "Available", "Away", "Busy", etc., indicators) but I don't use Pidgin (never have), or it could be an email indicator but I don't use Thunderbird (never have). There's nothing else I can see (left- or right-clicking) that identifies it. I'd like to get rid of it, but "Startup applications" only lists the ones I have optionally added, and this is not among them. Any help appreciated!

  • Why would you use EAP-TTLS instead of PEAP?

    - by Ivan Macek
    As I understood EAP-TTLS and PEAP share same level of security when implemented in wireless networks. Both only provide server side authentication via certificate. The drawback of EAP-TTLS can be non native support in Microsoft Windows so every user has to install additional software. The benefit of EAP-TTLS can be support for less secure authentication mechanisms (PAP, CHAP, MS-CHAP) but why would you need them in modern and properly secure wireless system? What are you opinions? Why should I implement EAP-TTLS instead of PEAP? Let's say that I have most Windows users, medium Linux users and least iOS, OSX users.

  • Cheapest Embedded System with Wireless Connectivity?

    - by geeko
    Problem: I'm trying to capture some information coming from keyboard, mouse and barcode reader connected to some PC via PS/2, USB and/or RS-232, before information get to PC and send it over the Internet to some central server. I'm thinking to do so by using some kind of hardware interface (middleware, if you like) between PC and input devices. I thought this interface can be embedded PC, PDA or simply some mobile phone with wireless connectivity. PS/2 and RS-232 could be converted to USB using some USB convector/hub that connects to one of these interface systems. Then some special API programming take place to communicate between PC, input devices and wireless server, in the form of application running on the interface system. What's the cheapest solution that can achieve this? Or possibly any other solution?

  • Adding sub-entities to existing entities. Should it be done in the Entity and Component classes?

    - by Coyote
    I'm in a situation where a player can be given the control of small parts of an entity (i.e. Left missile battery). Therefore I started implementing sub entities as follow. Entities are Objects with 3 arrays: pointers to components pointers to sub entities communication subscribers (temporary implementation) Now when an entity is built it has a few components as you might expect and also I can attach sub entities which are handled with some dedicated code in the Entity and Component classes. I noticed sub entities are sharing data in 3 parts: position: the sub entities are using the parent's position and their own as an offset. scrips: sub entities are draining ammo and energy from the parent. physics: sub entities add weight to the parent I made this to quickly go forward, but as I'm slowly fixing current implementations I wonder if this wasn't a mistake. Is my current implementation something commonly done? Will this implementation put me in a corner? I thought it might be a better thing to create some sort of SubEntityComponent where sub entities are attached and handled. But before changing anything I wanted to seek the community's wisdom.

  • New host, high load?

    - by dotancohen
    A few minutes ago I signed up at a new webhost. I have yet to move my sites over. Upon initial SSH connection, I checked the load and memory usage, they do seem rather higher than I would like: # uptime 12:06:51 up 71 days, 23:23, 1 user, load average: 9.02, 9.49, 9.45 # free total used free shared buffers cached Mem: 33014800 31927192 1087608 0 2384812 17729816 -/+ buffers/cache: 11812564 21202236 Swap: 16787916 8584 16779332 Is that a bit to packed? I'm only paying about $5 USD per month, so I don't expect <0.1 loads, but ~10 is worrisome. Is it not? Also, there is no /etc/issue file so I tried other methods to guess the OS: # uname -a Linux box358.bluehost.com 2.6.32-20120131.55.1.bh6.x86_64 #1 SMP Tue Jan 31 15:43:27 EST 2012 x86_64 x86_64 x86_64 GNU/Linux # which yum /usr/bin/yum # which apt-get # That looks like CentOS / RHEL 6.2 possibly?

  • How to see what's going on during shutdown

    - by Huygens
    Since a few weeks, Ubuntu freezes almost everytime when I shut it down. I know it because the shutdown animation stops and nothing is responsive: Ctrl+Alt+Del or AltGr+Syst+[r,e,i,s,u,b] don't make any difference. I have tried to look at various log files in /var/log but only INFO level message are logged. My hope to solve this problem would be to do a verbose shutdown, one where I could see what's going on, and so what's causing the problem, so I could start solving it. Therefore, as the title suggest it. Is there a way to see what's going on during shutdown? I could even go to the extreme of doing a step-by-step shutdown if this is the only way. Thanks for any tips.

  • "merging" multiple hardrives for Ubuntu 14.04 install

    - by Thijser
    I have 3 hardrives inside my laptop 2 of which currently house other opperating systems but have a empty partitions of 8 and 9 gigabye and the third is just 12 gB (currently not partitioned at all). Now each of these 3 is to small to be useful to me, however combined they are 29gigs which can easily hold a ubuntu installation, and associated programs. Is there a way set up my installation in such a way that it threads these 3 disks as one? Or is there a way by which I can make it default storage of many things into one drive (downloads and sudo apt-get install for example) to one drive while keeping ubuntu onto another?

  • Preparing a new physical system with VMWare

    - by Max
    I need to create a new installation of Windows, but at the same time I need this computer. So I decided to create a new physical disk from within VMWare, install windows/drivers/software and then just replace the HDD in the computer. I've bought a new HDD, split it into two partions and installed Windows 7 using the VMWare's ability to use phusical disks. I can see the windows files and directories that have been created on this partition, but when I'm replacing the HDD in the host machine it cannot boot from it. Why is that? Is it at all possible to create a bootable physical disk with VMWare or I should create a virtual disk and then use some HDD imaging tool to copy the HDD image to a physical disk? Maybe there's a better way of installing a new system and working on the computer at the same time?

  • How to make sure Windows PC is reasonably secure?

    - by Coder
    I'm not much of a network and network security expert, but I need to add an existing Windows PC to a network with always on connection. The problem is, I have no idea if the PC is really clean, and, actually, no knowledge to check it. I scanned the PC with Process Explorer to verify if all running processes are signed, ran an AVG scan, but this is where my knowledge ends. IIRC, there can be bad code attached to svchost or something, bad drivers, and so on, but I have no idea how to check all those things. Reformatting the PC is unfeasible as of now. Are there any suggestions on what I could do?

  • Do you run anti-virus software?

    - by Paolo Bergantino
    Do you find the crippling effect that most anti virus software has on a computer's performance worth the "security" they provide? I've never been able to really tell myself its worth it, and have used my computer without "protection" for years without any problems. Jeff Atwood wrote about this a while back, taking a similar stance. So I'm looking for some discussion on the merits and downfalls of antivirus software, and whether you personally think its worth the hassle. One point I do think is valid is that I am probably okay with not running it because I know if something goes wrong I have the ability to make it right (most of the time) but I can't really recommend the same for family as they may not be able to...

  • How does operating system software maintains time clocks?

    - by Neeraj
    Hi everyone, This may sound a bit less relevant but I couldn't think of a better place to ask this question. Now consider this situation, you install an OS on your system, set the timezone and time, do some stuff and turn it off. (Note that there is no power going in to the computer). Now next time (say after some hours or days) you turn it on again, and you see the updated time. How is this possible even when my computer is not connected to the internet and was consuming no power during the period it was down.(Is there some kind of hardware hack?) please clarify!

  • Solved: Operation is not valid due to the current state of the object

    - by ChrisD
    We use public static methods decorated with [WebMethod] to support our Ajax Postbacks.   Recently, I received an error from a UI developing stating he was receiving the following error when attempting his post back: {   "Message": "Operation is not valid due to the current state of the object.",   "StackTrace": "   at System.Web.Script.Serialization.ObjectConverter.ConvertDictionaryToObject(IDictionary`2 dictionary, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)\r\n   at System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)\r\n   at System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)\r\n   at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal(Int32 depth)\r\n   at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeDictionary(Int32 depth)\r\n   at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal(Int32 depth)\r\n   at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeDictionary(Int32 depth)\r\n   at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal(Int32 depth)\r\n   at System.Web.Script.Serialization.JavaScriptObjectDeserializer.BasicDeserialize(String input, Int32 depthLimit, JavaScriptSerializer serializer)\r\n   at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize(JavaScriptSerializer serializer, String input, Type type, Int32 depthLimit)\r\n   at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize[T](String input)\r\n   at System.Web.Script.Services.RestHandler.GetRawParamsFromPostRequest(HttpContext context, JavaScriptSerializer serializer)\r\n   at System.Web.Script.Services.RestHandler.GetRawParams(WebServiceMethodData methodData, HttpContext context)\r\n   at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)",   "ExceptionType": "System.InvalidOperationException" }   Goggling this error brought me little support.  All the results talked about increasing the aspnet:MaxJsonDeserializerMembers value to handle larger payloads.  Since 1) I’m not using the asp.net ajax model and 2) the payload is very small, this clearly was not the cause of my issue. Here’s the payload the UI developer was sending to the endpoint: {   "FundingSource": {     "__type": "XX.YY.Engine.Contract.Funding.EvidenceBasedFundingSource,  XX.YY.Engine.Contract",     "MeansType": 13,     "FundingMethodName": "LegalTender",   },   "AddToProfile": false,   "ProfileNickName": "",   "FundingAmount": 0 } By tweaking the JSON I’ve found the culprit. Apparently the default JSS Serializer used doesn’t like the assembly name in the __type value.  Removing the assembly portion of the type name resolved my issue. { "FundingSource": { "__type": "XX.YY.Engine.Contract.Funding.EvidenceBasedFundingSource", "MeansType": 13, "FundingMethodName": "LegalTender", }, "AddToProfile": false, "ProfileNickName": "", "FundingAmount": 0 }

  • System information shown when booting Debian

    - by WebDevHobo
    When booting Debian, you'll see it printing a lot of information about the system variables and such. I don't really need to see all that, so I'd like to modify some scripts to make sure that on boot, it just does what it has to do, without printing it on the screen. Just something I fancy. Offcourse, still seeing errors would be nice. But that long slur of text, I could do without. I've tried looking it up, but I can't find documentation on this specific thing anywhere.

Finding how a hacked server was hacked File permissions question The last one isn't directly related, but it highlights how easy it is to mess up with a web server administration. As there are several things, that can be done, before something bad happens, I'd like to have your suggestions in terms of good practices to limit backside effects of an attack and how to react in the sad case will happen. It's not just a matter of securing the server and the code but also of auditing, logging and counter measures. Do you have any good practices list or do you prefer to rely on software or on experts that continuously analyze your web server(s) (or nothing at all)? If yes, can you share your list and your ideas/opinions?

  • Spawn phone call from EC2 alerts

    - by Matt
    I have a system setup on AWS/EC2, it currently is using their CloudWatch alert system. The problem is this sends just to email, when ideally I would like this to be making a phone call and/or sending text messages to certain phone numbers when an alert fires (Note that I do not need the phone call to actually say anything, just call the person). We are trying to solve the problem that Amazon alerts are only useful if people are checking their email, which isnt always the case because all server problems love to happen at 4am on saturday... Please respond with any possible solutions/ideas, ideally I do not want to implement an entire monitoring system (IE: Nagios) on top of everything to handle this.
