How to Make a Bootable Antivirus Disc

Purpose of this document.
This document will teach you how to make a bootable anti-malware ( bootable antivirus ) cd/dvd step-by-step.  

Why Bootable Antivirus?
In a bootable environment we are running a stripped down version of windows in a ram disk (programs are loaded directly into ram), thus the hard drive on the PC is treated as attached storage (like a flash drive). In this state malware (malware consists of viruses, trojans, spyware, adware, rootkits, etc) is helpless and totally at your mercy. This is the best free way to remove any piece of malware with a 100% success rate.

Steps:
Please follow all the steps below:

1. Go to http://ubcd4win.com/downloads.htm
 
2. Select a mirror with a green status. (like "Mirror#3" for example)
 
3. When you click on the mirror it will take you to another site where the download will be available.
 
4. Click the download link for Ultimate Boot CD and save the download to wherever you download stuff.
 
5. Once the installer has been downloaded double click it.
 
6. Choose your language
 
7. Click next about 3 more times and select the file path where you would like to install ultimate boot cd 4 win. Please note that you should have a drive with at least 5-10 gb of free space to allow for future plugin growth. I will choose C:UBCD4Win. The install should take a few minutes.
 
8. Click Yes to the MD5 Hash Check. The install will continue once the hash check succeeds.
 
9. Click Yes to see if a patch file exists.
 
10. Click the checkbox to launch ubcd4winbuilder.exe.

11. Click the "i agree" button.
 
12. Click "NO" to searching for windows files.
 
13. Obtain a windows xp operating system disc w/SP2.
 
14. Explore the disc and copy the entire content (all the folders and files on the windows xp cd) to any location on your computer. You should allocate at least 700 MB of free space for the windows xp disc.
 
15. Open UBCD4win (if it's not already open). Click Source browse button (3 dots ...) and browse to your i386 folder. My path was C:WindowsXPcd for example.
 
16. Next go to the media output section and choose a spot for your ISO image to be created. This ISO can be burned with almost any burning software. Once the ISO is burned it will be bootable.
 
17. Next, click the plugins button. Don't be too overwhelmed here, actually you should be very happy! Look at all those plugins!
 
18. Now it's time to update our anti-malware software packages.
 
19. The first one I have on my list is a-squared free anti-spyware. Click that line and then click the config button. A command prompt will automatically open and start downloading the latest updates for that program...totally awesome, isn't it!
 
20. So, now you need to update all the anti-malware programs in our plugin list. Click each one and then hit the config button.
 
21. After you're done configing/updating your plugins click the close button.
 
22. Next, click Build.
 
23. Click yes to create a directory and then click i agree.
 
24. At this point your ISO is created and is ready to be burned.

This concludes the How to Make a Bootable Antivirus CD tutorial.

Computer hardware is a physical part of a computer that executes within the hardware. It is unlike computer software or data that can be frequently changed, modified or erased on a computer. Computer hardware is not frequently changed and so is stored in hardware devices such as read only memory (ROM) where it is not readily changed.  


Most computer hardware is embedded and so is not visible to normal users. Below are the different types of hardware's found in a computer.

Ø Motherboard: It is the central or primary circuit board making up a complex electronic system such as a computer. A motherboard is also known as a main board, logic board or system board.

Ø Central processing Unit: A CPU is the main component of a digital computer that interprets instructions and process data in computer programs.

Ø Random Access Memory: A RAM allows the stored data to be accessed in any order. RAM is considered as the main memory of the computer where the working area is used for displaying and manipulating data.

Ø Basic Input Output System: BIOS prepares the software programs to load, execute and control the computer.

Ø Power Supply: Power Supply supplies electrical energy to an output load or group of loads.

Ø Video Display Controller: It converts the logical representation of visual information into a signal that can be used as input for a display medium.

Ø Computer Bus: It is used to transfer data or power between computer components inside a computer or between computers.

Ø CD-ROM drive: It contains data accessible by a computer

Ø Floppy disk: It is a data storage device

Ø Zip Drive: It is a medium capacity removable disk storage system.

One must distinguish between the two, because they form the basis and reason, justify the selection of data elements that require special attention in the context of Information Security and usually also give the reason and the obligation to protect with the help of data Security Company. Most of data is leaked via website ,which can be prevented with the help of Website security company. 

During an interview with expert from network security company, although the difference between Information Security and Data Protection as a motive or obligation of security activities but the security measures applied are the same.

Information Security is required to protect the data and is used to avoid their loss and non-authorized modification. Data Protection should first ensure the confidentiality, integrity and availability of data, however there are more requirements such as authenticity among others.

Hire Best Facebook App Developers and Carry the Day!

by : ShannonCarnton

If you are involved in Facebook app development, either as a development company or an individual, you must create some promising apps or games to reach to great heights in this field. For the former one, it is very important to hire the best minds, which not only give their best in coding related stuffs but has his/her own exceptional ways of thinking and capability to work well in the team. In this article, we will discuss on the important elements you should ponder upon, when you are to Hire Facebook Programmer which could help you deplete the risk factor involved in the same:


Pre-preparation:

• Go-through the concepts: Though you are extremely expert and experienced in the Facebook app development, before seeking for the developers, you should do the necessary homework from your side. Whichever good companies I have read about, have one great point – at the end of interview they ask the candidate if they want to ask something. There is the possibility that they may ask something from any area of the field or related field and if you, as an interviewer are not able to answer it, it can create wrong impression.

• Novice or Experienced? Most of the companies face the ambiguity, whether to go with the novice developers or experienced one. To this point I would say, it depends on the type of project you want to hire the developers for. Many companies prefer the fresh minds because they are probably more enthusiastic in learning the things and they are like wet clay, whatever falls on their mind makes the concrete impression as time passes. Also, if you want to get done the most complex projects, it is preferable to go for the veteran developers owing to their experience in the field. Again, as a recruiter, I believe, there is no concrete delineation between the experienced and novice developers. I have seen many 2-3 years experience people who are just stagnant and cannot do the things which are slightly out of their comfort areas and the fresher's who are too versatile that they get ready to do any difficult task given to them through their efforts; whether they do or not, the positive approach matters a lot because most of the time under the guidance of seniors they do it well.

Ask something out of books

With this point, I want to put light on asking the intelligent questions. If you are a versatile company, this point is of utmost importance for you. Creating the applications requires some out-of-box thinkers. Please do not mistake the smart thinkers with complex thinkers. For creating the apps, you should hire Facebook programmer who can develop the apps which any user would love to use. For instance, Candy Crush Saga application is not a complex application, yet there are millions of users who love to play the game. So my point here is your app should touch the heart of user and insist them to use the app. This can be done only if you have great team and minds.

Information security training is MUST

by : David Thomas

Security researchers have discovered a new version of the Stuxnet malware, known as "Havex" which was used in a series of cyber attacks against the above organizations in the energy sector.  As you will see in most cases, the affected sector is the energy sector. The famous Stuxnet worm was designed to sabotage the Iranian nuclear plants, now, the new version is scheduled to affect software systems for industrial control SCADA and ICS capabilities disable devices in hydroelectric dams, as well nuclear power plants and even disable power grids using these types of devices.

The so-called Backdoor: W32 / Havex.A and variants of names depending on the antivirus vendor is a remote access Trojan generic and has recently been detected in a series of European companies that develop software applications for SCADA and ICS.  Havex is equipped with a new component, whose purpose is to collect information from the network and connected devices by leveraging the OPC (Open Platform Communications) standard. OPC is a communication standard that allows interaction between Windows-based SCADA applications and process control hardware. The malware scans the local network for devices that respond to requests from OPC to collect information about industrial control devices and then sends that information to its command and control server (C & C). Intelligence on development, has prepared the Havex in a function to collect information and send it to a server for developers of this worm, can enhance the Havex more precise functions make efficient and achieve the attack.  One of the issues which are companies that own these types of devices is still using SCADA with very tight versions of Windows that do not support or upgrades that may mitigate some of these safety issues and lack of Information Security Training emphasis on staff adds another level of threats. What we recommend is that the production line or that have SCADA network that has the following protections:


1) Where the SCADA LAN not have Internet access,

2) The teams are not accessible from the LAN to the users working in the company network.

3) If you must transfer files, do another VLAN or a segmented network and use services such as FTP or similar.

4) Do not allow the use of SCADA pendrive in those devices that support it. Transferring files to the same should be through a secure channel.
