Here is a fictional scenario we can use to illustrate the use of the XCACLS tool. We need to move or copy 50GB worth of data that is comprised of several thousand directories containing hundreds of thousands of small files from one storage system to another. These systems happen to part of a Windows 2000 Domain and permissions are quite granular in definition. We start the replication of that data using a favorite replication or synchronization tool and walk away for the evening. When we return the next day, everything has copied and all looks well. That is until you try to access the data.

The Data Is Copied, But I Cannot Access It: Permissions Security Problem
————————————————–
What you did not know, until just now, is that the root directory of the drive that you copied the data to had the wrong permissions assigned to it. In addition, inheritance was configured such that any data that is placed on the drive is over written with the permissions of the root directory. In this case, it was an old account that no longer existed. Believe it or not, that can happen, and system administrators will know what I am talking about. Now you are left with trying to figure out what to do. Do I format the new drive, change the permissions and inheritance on the root directory so they are correct and start all over again? Do I make the changes on the root drive so they have the correct permissions and wait hours upon hours for the permissions to propagate? No, there is another, very fast way of resolving this issue with XCACLS or another tool called SUBINACL.

XCALCS Quickly Resets Permissions On Directories And Files
—————————-
Becasue I have limited space in this article, I am going to use XCACLS as the tool to correct this problem. However, in complex permissions structures, you will most likely want to use SUBINACL to fix the issue. I will talk about SUBINACL briefly at the end of the article.

XCACLS as a very fast tool that can set, remove, add, and change permissions on files and directories. For intance, the following command replaces all existing access rights and accounts with that of “dmiller” on the file “file.txt” with read-only access: “xcalcs file.txt /Y /T /G domaindmiller:r”. Although that is pretty easy and helpful, what about changing all my directories and files, which I have thousands of, to allow the domaindmiller account to have full access? To do this in a very fast fashion you could execute the following from the root directory of the drive: “for /d %g IN (*.*) DO xcacls “%g” /Y /T /G domaindmiller:f”. This will go through every directory, subdirectory, and file and replace the current permissions with dmiller having full access to the object. You’ll notice I put “” around the %g in the example. This is not required, but if you have directories that have names with spaces in them you will need to have the “”.

What Other Ways Can I Use XCACLS To Change Security Permissions
———————————————————-
To give you a few additional handy examples of how you can use this tool take a look at the follow command prompt methods for replacing, updating and removing accounts and permissions from large numbers of directories and files.

The following command replaces all existing access rights an accounts with that of dmiller with read only access rights:
for /d %g IN (*.*) DO xcacls “%g” /Y /T /G domaindmiller:r

The following command does not replace existing account permissions, instead, it adds the account, in the example the local admin account, with read only permissions:
for /d %g IN (*.*) DO xcacls “%g” /Y /E /T /G administrator:r

The following command removes the account “administrator” permissions from all directories, files, and subdirectories: for /d %g IN (*.*) DO xcacls “%g” /Y /E /T /R administrator

This command should update all the directories and their contents to allow Domain Admins full access:
for /d %g IN (*.*) DO xcacls “%g” /Y /T /G “Domain Admins:f”

I did a test on my XP Pro workstation and was able to change the permissions on approximately 10000 directories and files in less 1 minute. On one of my servers I was able to achieve a 500% increase in speed. It is blazingly fast.

SUBINACL Is More Complex But Man Can It Really Save The Day
———————————————–
I cannot go into specifics about this tool in this article but I will tell you what it can do. And again, it does it very very fast. Using the same scenario as above, let’s say that you had to fix the permissions on thousands of home directories. With SUBINACL, you can actually go to the original directories and files, use the tool to create what is called a “play file”, a text file that contains the right account and permissions from the source files, then use that same file to tell SUBINACL to fix the permissions on the target storage system, the one with the screwed up permissions. It’s quite the life saver if you ever find yourself in the type of predicament.

Also check out “CACLS”. This command is inherent to Windows XP Professional.

Conclusion
———-
These tools are contained in the Windows 2000 and 2003 server resource tool kit, however several of them also exist native to the Windows XP environment. Check them out if you don’t already know about them. Even if you have no use for them right now it may save you hours of hard work and stress in the event of a future permissions problem.

Data recovery is a time consuming process that most of the time requires some level of technical knowledge in order to keep the integrity of the destroyed data destroyed no matter what the cause. Hard drive data recovery, when performed the wrong way, can lead to permanent data loss and even damage the surface.

Therefore, when it comes to deciding on data recovery software or professional data recovery service, stop for a while and think about it twice. How much do you know about the recovery processes? Are your computer skills enough to perform the operation by yourself? Is the software comprehensible and easy to use? Are there any warranties of full data recovery?

To all those questions, add the most important:
How critical is it for you or your business to recover the data that was lost?

Keep in mind that a professional service can recover all types of files, because they have the full versions of the most advanced data recovery software. Furthermore, they can also preview the files before recovering them so you will be provided with a data recovery from where you can choose which selected files to be retrieved or ask for all of them back.

Even when the hard drive data recovery is exposed to severe recovery situations, professional data recovery services can include additional support for over 300 specific file types and uncommon file types such as FLV and flash files, MIDI music files, digital media files, voice files, and many others.

Another service that professionals can offer and you probably will not be able to implement, except if you are an IT technician, is the emergency boot media, which allows you to recover data from systems that cannot boot Windows due to data loss, hard drive damage or virus attack.

Sometimes you can have the knowledge and skills, the data recovery software, but not the time. Professional services can perform the recovery because of time constraints, offering a solution for almost any hard drive situation or the critical nature of the data recovery.

Such hard drive data recovery solutions may include the most advanced data recovery software, including disk diagnostic and file repair, the best disk diagnostic tools, improved file type searching capabilities, and the confidence that your most important information is in good hands to be rescued.

What You Can Use to Recover Microsoft Office Passwords like a Professional
Meet Accent OFFICE Password Recovery (http://passwordrecoverytools.com/), a tool that’s used by password recovery specialists. More importantly, it’s the tool that can recover your password and do it fast:no matter how complex your password was.
Accent OFFICE Password Recovery can easily access many documents. To make a long story short, not all Microsoft Office documents are equally well-protected. Certain versions and certain types of passwords can be broken instantly without the need of long password-crunching routines. How can you tell if your documents fall into this category? Download a free copy of Accent OFFICE Password Recovery from http://passwordrecoverytools.com/ to see if your password can be instantly removed.
What if your document was encrypted with a strong password and cannot be recovered instantly? If so, Accent OFFICE Password Recovery will try different passwords until it finds one that fits. Modern computers are fast, so fast that hundreds of thousands of different passwords can be tried every second. Your typical “123″ password will be cracked in no time!
What if your company policies mandate having longer than normal passwords? In that case, it may take longer. How much longer? That depends on what you remember about the password.

Typical password recovery applications use two methods to guess passwords. The first one to try is always a dictionary attack, which attempts combinations of different words from plain English or other languages. There are not that many words in any language, which allows this attack to attempt all possible combinations quickly. If your password did not contain dictionary words, a password recovery tool will typically use the so-called brute force attack, attempting every possible combination of letters, numbers, and special symbols as a suggested password. This approach can take days or even weeks, if you had a really long password!

Accent OFFICE Password Recovery may solve the puzzle much faster than typical tools by using a third approach. If you remember something – even a little bit – about your password, Accent OFFICE Password Recovery can use this information to restrict the number of possible combinations and recover your password much faster than usual. This approach, which is unique to Accent OFFICE Password Recovery, is called masking. You can define the mask used in your password in an easy visual manner. Are you certain that your password started with a capital letter? Define a mask using that restriction, and Accent OFFICE Password Recovery won’t attempt any lower-case characters, making password recovery twice as fast. Did your password end with a number? Add another mask and your time savings are three-fold. Does your corporate policy demand passwords longer than 7 characters? Accent OFFICE Password Recovery won’t try passwords shorter than that, and you gain even more time.
Accent OFFICE Password Recovery provides you with an easy Wizard that helps you create a custom attack on your password, ensuring the fastest turnaround for the most complex passwords.
Accent OFFICE Password Recovery is not your typical “do-it-yourself” tool aimed at the occasional user who forgot a password that happens to be “123″. This product is designed to effectively crunch and solve passwords that are much more complex, and it does it fast. In fact, it can recover many passwords in just seconds!

Computer Security And Survivable Computer Systems
————————————————–
Survivable computer systems and computer security are in many ways related but at a low-level very much different. For instance, the hardening of a particular system to be resistant against intelligent attacks may be a component of a survivable computer system. It does not address the ability of a computer system to fulfill its purpose when it is impacted by an event such as a deliberate attack, natural disaster or accident, or general failure. A survivable computer system must be able to adapt, perform its primary critical functions even if in a hostile environment, even if various components of the computer system are incapacitated. In some cases, even if the entire “primary” system has been destroyed.

As an example; a system designed to provide real-time critical information regarding analysis of specialized medications ceases to function for a few hours because of wide spread loss of communication. However, it maintains the validity of the data when communication is restored and systems come back online. This computer system could be considered to have survived under conditions outside of its control.

On the other hand, the same system fails to provide continuous access to information under normal circumstances or operating environment, because of a localized failure, may not be judged to have fulfilled its purpose or met its objective.

Fault Tolerant And Highly Availability Computer Systems
—————————-
Many computer systems are designed with fault tolerant components so they continue to operate when key portions of the system fail. For instance; multiple power supplies, redundant disk drives or arrays, even multiple processors and system boards that can continue to function even if its peer component is destroyed or fails. The probability of all components designed to be redundant failing at one time may be quite low. However, a malicious entity that knows how the redundant components are configured may be able to engineer critical failures across the board rendering the fault tolerant components ineffective.

High availability also plays a role in a survivable computer system. However this design component may not maintain computer system survivability during certain events such as various forms of malicious attack . An example of this might be a critical web service that has been duplicated, say across multiple machines, to allow continuous functionality if one or more the individual web servers was to fail. The problem is that many implementations of high availability use the same components and methodology on all of the individual systems. If an intelligent attack or malicious event takes place and is directed at a specific set of vulnerabilities on one of the individual systems, it is reasonable to assume the remaining computer systems that participate in the highly available implementation are also susceptible to the same or similar vulnerabilities. A certain degree of variance must be achieved in how all systems participate in the highly available implementation.

What’s The Difference Between An Attack, Failure, And Accident?
How Do These Differences Impact A Survivable Computer System
———————————————————-
In many cases when I am discussing the security of systems with customers, the question of business continuity and disaster recovery come up. Most companies that provide a service that they deem critical just know the system needs to be operational in a consistent manner. However, there is typically little discussion about the various events or scenarios surrounding this and that can lead to great disappointment in the future when what the customer thought was a “survivable computer system” does not meet their expectations. Some of the items I like to bring up during these conversations is what their computer systems goal and objective is, what specifically does continuous operation mean to them, and specifically what constitutes an attack, failure, or accident that can cause loss of operation or failure to meet objectives.

A failure may be defined as a localized event that impacts the operation of a system and its ability to deliver services or meet its objectives. An example might be the failure of one or more critical or non-critical functions that effect the performance or overall operation of the system. Say, the failure of a module of code that causes a cascading event that prevents redundant modules from performing properly. Or, a localize hardware failure that incapacitates the computer system.

An accident is typically an event that is outside the control of the system and administrators of a local / private system. An example of this would be natural disasters such as hurricanes, if you live in south Florida like I do, or floods, or wide spread loss of power because the utility provider cut the wrong power lines during an upgrade to the grid. About two years ago, a client of mine who provides web based document management services could not deliver revenue generating services to their customers because a telecommunications engineer cut through a major phone trunk six blocks away from their office. They lost phone and data services for nearly a week.

An now we come to “attack”. We all know accidents will happen, we know that everything fails at one time or another, and typically we can speculate on how these things will happen. An attack, executed by an intelligent, experienced individual or group can be very hard to predict. There are many well known and documented forms of attacks. The problem is intelligence and human imagination continuously advance the form of malicious attacks and can seriously threaten even the most advanced designed survivable computer systems. An accident or failure does not have the ability to think out of the box or realize that a highly available design is flawed because all participants use the same design. The probability that an attack might occur, and succeed may be quite low, but the impact may be devastating.

Conclusion
———————————————–
One of the reasons I wrote this article was to illustrate that it’s not all about prevention. Although prevention is a big part of survivable computer system design, a critical computer system must be able to meet its objectives even when operating under hostile or stressful circumstances. Or if the steps taking for prevention ultimately prove inadequate. It may be impossible to think of all the various events that can impact a critical computer system but it is possible to reasonably define the possibilities.

The subject of survivable computer systems is actually one of complexity and ever evolving technology. This article has only touched on a few of the basic aspects of computer system survivability. I intend on continuing this article to delve deeper into the subject of survivable computer systems.

While paper records secured within a fire-rated safe can withstand temperatures up to 350 degrees Fahrenheit, computer media is damaged beyond use by temperatures above 125 degrees and 80% humidity. Microfiche film, tapes, diskettes, CDs, DVDs and computer media require the added protection of a data media safe.

Data Media Safes are specifically designed for data media storage. Protect against fire and climactic changes–a requirement for a small business or home office. A data media safe must keep the internal temperature below 125 and the humidity level below 85%. Several fire testing laboratories have tested our safes at a temperature of 1,832 degrees F for over one hour with internal temperatures remaining below 122 degrees F. The safes were awarded the one-hour label. In addition, the safes are manufactured under ISO 9002 quality standard requirements.

Fire could destroy your business! In fact, eight businesses burn almost every hour in the U.S. resulting in over 2.3 billion dollars in annual losses.* Unfortunately, seven out of ten businesses have not adequately protected their vital records. When that information is destroyed a business often fails. Don’t become a company that incurs fire damage resulting in critical loss of data (customer, personnel, accounting files, etc.) by not utilizing quality fire and data media safes. Survival is possible but preparation is necessary.

Instead of tearing out your hair over a stubborn computer that is holding that essential file hostage, let the worries slide away and send off your hard drive to a data recovery company. These companies work their magic and recover files of all sizes in a remarkably quick turn around time. This service is essential for any individual or business that has fallen onto hard times with their computer.

Most data recovery companies operate over the internet and occupy cyberspace as they would a store front. If you find yourself in need of a quality company to find your files, look no further than the World Wide Web.

A simple search of search engines will produce hundreds of quality companies eager to solve your every problem. Before you send off your hard drive, carefully evaluate the chosen company to ensure it is legitimate and reputable. Using an incorrect company may result in further headaches and a loss of money for services not rendered.

Upon your search for a data recovery company, investigate their capabilities and services. Choosing a company that will best serve your needs will ensure the greater success in the end. You may need to compare services versus charges for these data recovery companies.

The old adage, you get what you pay for could not be truer when it comes to regaining your lost files. If you are taking the trouble to send off your hard drive in an attempt to reclaim critical files for business or personal reasons, then you should be prepared to spend the appropriate amount of money to get the job done. However, just because one data recovery is more expensive than another one does not mean the pricier company is more successful.

When choosing a data recovery company to reclaim your files, consider contacting individuals who has used their services in the past. This recommendation to use or to avoid the company may be an excellent method to choosing a company.

Also, contact the company directly and explain your specific situation. A representative for the company will be able to discuss the possibility of the recovery of your files and the estimated cost of their services. You should be sure to inquire the expense if the company is unable to recover the lost files. Many companies offer to return your hard drive without charging for their services if they are unable to deliver your compromised files.

Whichever data recovery company you entrust to regain your lost files, be sure to keep the companys contact information if you are pleased with the services rendered. Having this resource can be invaluable if a similar fate befalls your files in the future and you need a reputable source to recover these files as quickly as possible. If you are pleased with the data recovery company, be sure to tell other individuals in your predicament.
