Free Antivirus Software.

Posted in Computers, Free, Internet, Security on May 7, 2008 by techuptodate

All of us use antivirus software for save computing. There are several excellent paid professional antivirus software like Norton Antivirus, McAfee, but they are expensive software and require yearly subscription fees for regular antivirus updates. So if some of you prefer to use free ones here is the list of free antivirus software that are available to download right now.

AVG Free edition Free edition of the AVG anti-virus program for Windows and Linux. Tested and recommended by Freebyte.com.
Avira Antivir Free anti-virus software for Windows, Linux, Free BSD and Solaris. Detects and removes more than 50,000 viruses. Free support.
BitDefender Freeware virus scanner for Linux.
Clam AV Freeware, GPL, Linux. Clam AntiVirus is a GPL anti-virus toolkit for UNIX. The main purpose of this software is the integration with mail servers (attachment scanning). The package provides a flexible and scalable multi-threaded daemon, a command line scanner, and a tool for automatic updating via Internet.
ClamWin Freeware, open-source anti-virus program for Windows.
Comodo Anti-Virus Free anti-virus program for Windows.
Cyberhawk Protects against viruses, worms, trojans and other spyware, designed to be a complement to your current anti-virus software. Cyberhawk does not need to know anything about a virus before it can protect you against it. This is because Cyberhawk looks at the behaviour of an infected program (instead of the contents of the infected file). The basic version is free.
Note from the editors: after testing Cyberhawk we found that it generates a lot of false alarms on legitimate software. Nevertheless we think that this program can be useful provided you know how to interpret these alarms.

Scroll Concept.

Posted in Technology on May 3, 2008 by techuptodate

The appearance of the scroll blue-sky design concept that takes a format used by medieval town criers have turned it sideways and shoe-horns it into the 21st century by incorporating a mobile phone, hand-held computer, camcorder and sliding LCD screen, gizma.com reports.

The “what might be” concept by Californian based video production and graphic/web designer Seth Haller envisions a 10 mega-pixel camera, 1080p camcorder, 6 watt speaker, wi-fi and Bluetooth enabled phone (and potentially any functionality that modern consumer electronics can offer) incorporated into a double-ended device that slides out to reveal a “solid state” LCD screen. We like it, although in terms of portability you’ve still got a device that’s the size of two-phones to contend with.

Haller, who used Autodesk 3DS Max to model The Scroll, believes a functional design modeled after his design could one day be possible, but at this stage there are no plans to move the concept beyond the drawing board.
Seth Haller can be contacted via the 13 Tech Design site.

Technical Trials for Sezmi.

Posted in Computers, Internet, Technology on May 2, 2008 by techuptodate

A startup is betting that people are tired enough of their cable and satellite bills to take a look at an alternative pay TV system that combines a number of different technologies to deliver programming, CNN reports.

Technical trials are starting soon for Sezmi, a company that hopes to bust into the TV business.
Silicon Valley-based Sezmi Corp. is revealing a system Thursday that amounts to a way for phone companies and local TV broadcasters to team up for an end run around satellite and cable. Technical trials are starting shortly, with full-blown commercial trials in some markets, yet unnamed, later this year.
The carrot for consumers: monthly fees that are about half those of cable or satellite, according to Sezmi founder Buno Pati.
Sezmi’s system takes some explaining. At its heart is a TV set-top box that receives video content in three different ways. Two are available through other means: digital over-the-air local broadcasts, the kind that are available to anyone with a digital TV and a rabbit-ear antenna; and Internet downloads through the home’s broadband connection.

The third delivery method would be unique to Sezmi. It plans to have local TV stations use vacant portions of their airwaves to transmit basic cable channels like Nickelodeon and Discovery. Given the limited spectrum available, the stations won’t be able to transmit a full lineup, and only some of it will be in high definition. Sezmi plans to mitigate that by having stations send out the most-watched shows and have the set-top boxes save them on their hard drives, making them available for viewing on demand.

None of these features are completely original. The set-top box combines the feature of a digital TV tuner, a TV-style digital video recorder and an Internet video box like the Apple TV. The additional over-the-air cable content is reminiscent of a service called MovieBeam, which was started by The Walt Disney Co. When it shut down in December after a four-year run, it had 1,800 subscribers.

“The TV space has been waiting for someone to put it all together much like Apple did for digital music” when it combined its iTunes music store with the iPod music player, said Phil Wiser, chairman and president of Sezmi.

Apart from questions about how well the complex system works, consumer confusion could be one of the obstacles to Sezmi’s success. It took years for mainstream consumers to understand what digital video recorders were good for, for instance.

Sezmi is counting on phone companies, and perhaps also wireless carriers, to market the service as a bundle with Internet service. A cheap TV product would give landline phone companies a way to fend off the encroachment of cable companies, who are rapidly signing up people for their voice services.

The largest phone companies, AT&T Inc. and Verizon Communications Inc., have their own TV services, but they’re expensive to roll out. Smaller companies, like Embarq Corp., have marketing deals with satellite companies, but those yield little in the way of synergies.

Sezmi did not announce any commitments from phone companies, but Jeff Gardner the chief executive of Windstream Communications Inc., said Sezmi creates “a unique opportunity for Internet service providers.” The Little, Rock., Ark., company operates 3.2 million phone lines.

Sezmi executives have a strong pedigree in the technology and media fields. Wiser, the chairman, used to be chief technology officer of Sony Corp. of America. Before that, he founded Liquid Audio, a pioneer in online music distribution. Pati founded Numerical Technologies, which developed a chip manufacturing technology. Other executives have backgrounds at NBC, DirecTV and Clearwire Corp., a wireless broadband provider. On the board is Andrew Lack, chairman of SonyBMG Music Entertainment.

By the way today you can check prepaid phone plans comparison tests online that will cost you less and reveal the ideal plan for you.

The Most Essential Security Measures.

Posted in Computers, Electronic Devices, Internet, Security, Technology on April 26, 2008 by techuptodate

There are 10 physical the most essential security measures every organization should take, if you haven’t already done so of course.

#1: Lock up the server room
The server room is the heart of your physical network, and someone with physical access to the servers, switches, routers, cables and other devices in that room can do enormous damage.

#2: Set up surveillance
No doubt you need a way to know who goes in and out and when.
A better solution than the log book is an authentication system incorporated into the locking devices, so that a smart card, token, or biometric scan is required to unlock the doors, and a record is made of the identity of each person who enters.

A video surveillance camera, placed in a location that makes it difficult to tamper with or disable (or even to find) but gives a good view of persons entering and leaving should supplement the log book or electronic access system. Surveillance cams can monitor continuously, or they can use motion detection technology to record only when someone is moving about. They can even be set up to send e-mail or cell phone notification if motion is detected when it shouldn’t be (such as after hours).

#3: Make sure the most vulnerable devices are in that locked room
Because it’s not just the servers you have to worry about. A hacker can plug a laptop into a hub and use sniffer software to capture data traveling across the network.
#4: Use rack mount servers
Rack mount servers not only take up less server room real estate; they are also easier to secure.
#5: Don’t forget the workstations
Hackers can use any unsecured computer that’s connected to the network to access or delete information that’s important to your business.

#6: Keep intruders from opening the case
Both servers and workstations should be protected from thieves who can open the case and grab the hard drive.

#7: Protect the portables
Handhelds can be locked in a drawer or safe or just slipped into a pocket and carried on your person when you leave the area. Motion sensing alarms such as the one at SecurityKit.com are also available to alert you if your portable is moved.

#8: Pack up the backups
Backing up important data is an essential element in disaster recovery, but don’t forget that the information on those backup tapes, disks, or discs can be stolen and used by someone outside the company..

Don’t overlook the fact that some workers may back up their work on floppy disks, USB keys, or external hard disks. If this practice is allowed or encouraged, be sure to have policies requiring that the backups be locked up at all times.

#9: Disable the drives
If you don’t want employees copying company information to removable media, you can disable or remove floppy drives, USB ports, and other means of connecting external drives.

#10: Protect your printers
You might not think about printers posing a security risk, but many of today’s printers store document contents in their own on-board memories. Also think about the physical security of documents that workers print out, especially extra copies or copies that don’t print perfectly and may be just abandoned at the printer or thrown intact into the trash can where they can be retrieved.
You have to remember that network security starts at the physical level. All the firewalls in the world won’t stop an intruder who is able to gain physical access to your network and computers, so lock up as well as lock down.

Save Your Computing.

Posted in Computers, Security on April 20, 2008 by techuptodate

Back in January there were multiple reports about a large number of web sites being compromised and serving malware, wrote Bojan Zdrnja, on the institute’s blog. “While we had a general idea about what they do during these attacks, and we knew that they were automated, we did not know exactly how the attacks worked, or what tools the attackers used,” Zdrnja wrote. Then he proposes some helpful advices to avoid that.

So, the tool does is this:

The user can configure the tag that will be inserted on the compromised web sites. By default, the tool we recovered had the following string embedded: http://www.2117966 [dot] net/fuckjp.js. Sounds familiar? See https://isc.sans.org/diary.html?storyid=4139
The tool then checks something with a site in China. My guess at this point in time is that the attackers get paid for this since the tool calls a script pay.asp with an argument SN to verify something.
Now the user can start the tool. It will connect to Google and will search for vulnerable sites with the following query string: inurl:”.asp” inurl:”a=”. The parameter is configurable and the tool can search for many strings. For crawling, the tool uses a built-in embedded browser from bsalsa (http://www.bsalsa.com)
Once the URLs have been identified, the tool tries to attack the web sites with SQL Injection (I still have to analyze this part further to see how it works). The SQL injection string, though, is visible in the file and formatted with the tag defined in the first. Here is how the SQL Injection statement gets formulated
DECLARE @T varchar(255),@C varchar(255) DECLARE Table_Cursor CURSOR
FOR select a.name,b.name from sysobjects a,syscolumns b where
a.id=b.id and a.xtype=’u’ a
nd (b.xtype=99 or b.xtype=35 or b.xtype=231 or b.xtype=167) OPEN
Table_Cursor FETCH NEXT FROM Table_Cursor INTO @T,@C
WHILE(@@FETCH_STATUS=0) BEGIN exec(’up
date ['+@T+'] set ['+@C+']=rtrim(convert(varchar,['+@C+']))+”
”’)FETCH NEXT FROM Table_Cursor INTO @T,@C END CLOSE Table_Cursor
DEALLOCATE Table_Cursor
;DECLARE%20@S%20NVARCHAR(4000);SET%20@S=CAST(
%20AS%20NVARCHAR(4000));EXEC(@S);–

The nice thing about this is that we finally managed to confirm that it is SQL Injection that was used in those attacks. The tool has more functionality that we still have to analyze but this is the main purpose.

Check your applications and make sure that they are not vulnerable. We covered this many times in various diaries, so here are few links to online resources that can help with this:

http://www.owasp.org/index.php/Top_10_2007-A2#Protection

http://weblogs.asp.net/scottgu/archive/2006/09/30/Tip_2F00_Trick_3A00_-Guard-Against-SQL-Injection-Attacks.aspx

http://portal.spidynamics.com/blogs/msutton/archive/2006/09/26/How-Prevalent-Are-SQL-Injection-Vulnerabilities_3F00_.aspx

http://erratasec.blogspot.com/2007/08/sql-injection-is-surpisingly-easy.html

Also “The SQL in question uses table cursors (as variable Table_Cursor) to enumerate all tables on Microsoft SQL server and the respective columns that are of type ntext, text, nvarchar, or varchar AND the table type is a user table and not a system table. The code then proceeds to utilize a cursor while loop to iterate through the returned results updating each table.columname concatenating it’s current value with an arbitrary value (which appears missing in your SQL, it would appear in the [HERE] area of the query part “rtrim(convert(varchar,['+@C+']))+’[HERE]‘”

The code converts the current data to varchar during concatenation to avoid any cast issues and removes any trailing space to the right of the field value.
The cursor is deallocated after update (how nice of them)”

Bojan’s dairy you can find here - http://isc.sans.org/diary.html?storyid=4294
Thanks him for great submissions.

Chance to Be Closer to the Matrix.

Posted in Technology on April 3, 2008 by techuptodate

New software Cyber MC from Orange Dreams will get you the chance to be closer to the Matrix. Can you believe it? There are quite a few things about the Cyber MC brainwave management solution that remain unclear to us, but it’s probably for the best. Korean startup Orange Dreams has apparently concocted some sort of eyewear / software combo that can control your brainwaves and calm your nerves.

There are numerous ways to lose weight or quit smoking, but most of those dated methods require will power and a desire for self improvement. With the new approach Orange Dream is going to help the persons that would rather spend money then exert effort. The Korean companies new Cyber MC glasses aim to help improve your education, loss weight, quit smoking, and relieve stress. If all else fails you can also play games with the glasses.

Details are still thin on how exactly these glasses take advantage of your ‘brain waves’, but it looks as if they flash images in an Orwellian brainwashing fashion. If you are ready to embrace this brave new world the Cyber MC the software and glasses will be available this April.

Vista Again.

Posted in Computers on March 21, 2008 by techuptodate

Mark Russinovich writes in his technical blog covering topics such as Windows troubleshooting, technologies and security about Vista SP1 File Copy problems: “During Windows Vista development, the product team revisited the copy engine to improve it for several key scenarios. One of the biggest problems with the engine’s implementation is that for copies involving lots of data, the Cache Manager write-behind thread on the target system often can’t keep up with the rate at which data is written and cached in memory. That causes the data to fill up memory, possibly forcing other useful code and data out, and eventually, the target’s system’s memory to become a tunnel through which all the copied data flows at a rate limited by the disk.

Another problem they noted was that when copying from a remote system, the file’s contents are cached twice on the local system: once as the source file is read and a second time as the target file is written. Besides causing memory pressure on the client system for files that likely won’t be accessed again, involving the Cache Manager introduces the CPU overhead that it must perform to manage its file mappings of the source and destination files.

A limitation of the relatively small and interleaved file operations is that the SMB file system driver, the driver that implements the Windows remote file sharing protocol, doesn’t have opportunities to pipeline data across high-bandwidth, high-latency networks like WLANs. Every time the local system waits for the remote system to receive data, the data flowing across the network drains and the copy pays the latency cost as the two systems wait for the each other’s acknowledgement and next block of data.

After studying various alternatives, the team decided to implement a copy engine that tended to issue large asynchronous non-cached I/Os, addressing all the problems they had identified. With non-cached I/Os, copied file data doesn’t consume memory on the local system, hence preserving memory’s existing contents. Asynchronous large file I/Os allow for the pipelining of data across high-latency network connections, and CPU usage is decreased because the Cache Manager doesn’t have to manage its memory mappings and inefficiencies of the original Vista Cache Manager for handling large I/Os contributed to the decision to use non-cached I/Os. They couldn’t make I/Os arbitrarily large, however, because the copy engine needs to read data before writing it, and performing reads and writes concurrently is desirable, especially for copies to different disks or systems. Large I/Os also pose challenges for providing accurate time estimates to the user because there are fewer points to measure progress and update the estimate. The team did note a significant downside of non-cached I/Os, though: during a copy of many small files the disk head constantly moves around the disk, first to a source file, then to destination, back to another source, and so on.”

LifeBook E8410.

Posted in Computers on March 18, 2008 by techuptodate

The first new model in the range is the LifeBook E8410, which replaces the E8210, and is Fujitsu PC’s flagship business model, offering the “top of the line” features and is most decidedly “top in performance”. For the discerning business user or consumer demanding the best-in-class performance, the E8410 is a superb desktop alternative offering supreme performance, superior security and truly comprehensive communications capabilities.

Thiss notebook could be recommended for business professionals, casual computing users, and some of the entry-level configurations of this notebook will work well for students or people on a budget. Of course, anyone looking for a quiet notebook should consider the E8410 as well.

The good: Interesting design, particularly for a mainstream business laptop; comfortable keyboard; plenty of ports
The bad: Overpriced; so-so battery life.
The bottom line: Although it’s a solidly constructed business laptop with an appealing design and decent performance, it’s hard to make a case for the Fujitsu LifeBook E8410 because it costs much more than competing 15-inch models.

Single-Crystal Semiconductor Materials News.

Posted in Electronic Devices, Technology on March 15, 2008 by techuptodate

An international science team from Penn State University in the United States and the University of Southampton in the United Kingdom has developed a process for growing a single-crystal semiconductor inside the tunnel of a hollow optical fiber, physorg.com reports. The device adds new electronic capabilities to optical fibers, whose performance in electronic devices such as computers typically is degraded by the interface between the fiber and the device.

“For most applications, single-crystal semiconductor materials have better performance than polycrystalline and amorphous materials,” said John Badding, associate professor of chemistry at Penn State. “We have now shown that our technique of encasing a single-crystal semiconductor within an optical fiber results in greater functionality of the optical fiber, as well.”

The team used a high-pressure fluid-liquid-solid approach to build the crystal inside the fiber. First, the scientists deposited a tiny plug of gold inside the fiber by exposing a gold compound to laser light. Next, they introduced silane, a compound of silicon and hydrogen, in a stream of high-pressure helium. When the fiber was heated, the gold acted as a catalyst, decomposing the silane and thus allowing silicon to deposit as a single crystal behind the moving gold catalyst particle, forming a single-crystal wire inside the fiber.

“The key to joining two technologies lies not only in the materials, but also in how the functions are built in,” said Pier Sazio, senior research fellow in the Optoelectronics Research Centre at the University of Southampton. “We were able to embed a nanostructured crystal into the hollow tube of an optical fiber to create a completely new type of composite device.”

The research team sees potential to carry the application to the next level. “At present, we still have electrical switches at both ends of the optical fiber,” said Badding. “If we can get to the point where the electrical signal never leaves the fiber, it will be faster and more efficient.”

Security Measures.

Posted in Computers, Internet, Security on March 14, 2008 by techuptodate

All electronic devices are very smart, that’s right but all of us learn that everything begins with the bottom, at the physical level. Likewise, when it comes to IT security, physical security is the foundation for our overall strategy. But some organizations, distracted by the more sophisticated features of software-based security products, may overlook the importance of ensuring that the network and its components have been protected at the physical level.

zdnet.com offers 10 of the most essential security measures you should implement now, if you haven’t already done so.

1. Lock up the server room
The server room is the heart of your physical network, and someone with physical access to the servers, switches, routers, cables and other devices in that room can do enormous damage.

2. Set up surveillance
Locking the door to the server room is a good first step, but someone could break in, or someone who has authorized access could misuse that authority. You need a way to know who goes in and out and when. A log book for signing in and out is the most elemental way to accomplish this, but it has a lot of drawbacks. A person with malicious intent is likely to just bypass it.

3. Make sure the most vulnerable devices are in that locked room
Remember, it’s not just the servers you have to worry about. A hacker can plug a laptop into a hub and use sniffer software to capture data traveling across the network. Make sure that as many of your network devices as possible are in that locked room, or if they need to be in a different area, in a locked closet elsewhere in the building.

4. Use rack mount servers
Rack mount servers not only take up less server room real estate; they are also easier to secure. Although smaller and arguably lighter than (some) tower systems, they can easily be locked into closed racks that, once loaded with several servers, can then be bolted to the floor, making the entire package almost impossible to move, much less to steal.

5. Don’t forget the workstations
Hackers can use any unsecured computer that’s connected to the network to access or delete information that’s important to your business. Workstations at unoccupied desks or in empty offices (such as those used by employees who are on vacation or have left the company and not yet been replaced) or at locations easily accessible to outsiders, such as the front receptionist’s desk, are particularly vulnerable.

Disconnect and/or remove computers that aren’t being used and/or lock the doors of empty offices, including those that are temporarily empty while an employee is at lunch or out sick. Equip computers that must remain in open areas, sometimes out of view of employees, with smart card or biometric readers so that it’s more difficult for unauthorized persons to log on.

6. Keep intruders from opening the case
Both servers and workstations should be protected from thieves who can open the case and grab the hard drive. It’s much easier to make off with a hard disk in your pocket than to carry a full tower off the premises. Many computers come with case locks to prevent opening the case without a key.

You can get locking kits from a variety of sources for very low cost, such as the one at Innovative Security Products.

7. Protect the portables
Laptops and handheld computers pose special physical security risks. A thief can easily steal the entire computer, including any data stored on its disk as well as network logon passwords that may be saved. If employees use laptops at their desks, they should take them with them when they leave or secure them to a permanent fixture with a cable lock, such as the one at PC Guardian.

Handhelds can be locked in a drawer or safe or just slipped into a pocket and carried on your person when you leave the area. Motion sensing alarms such as the one at SecurityKit.com are also available to alert you if your portable is moved.

For portables that contain sensitive information, full disk encryption, biometric readers, and software that “phones home” if the stolen laptop connects to the Internet can supplement physical precautions.

8. Pack up the backups
Backing up important data is an essential element in disaster recovery, but don’t forget that the information on those backup tapes, disks, or discs can be stolen and used by someone outside the company. Many IT administrators keep the backups next to the server in the server room. They should be locked in a drawer or safe at the very least. Ideally, a set of backups should be kept off site, and you must take care to ensure that they are secured in that offsite location.

Don’t overlook the fact that some workers may back up their work on floppy disks, USB keys, or external hard disks. If this practice is allowed or encouraged, be sure to have policies requiring that the backups be locked up at all times.

9. Disable the drives
If you don’t want employees copying company information to removable media, you can disable or remove floppy drives, USB ports, and other means of connecting external drives. Simply disconnecting the cables may not deter technically savvy workers. Some organizations go so far as to fill ports with glue or other substances to permanently prevent their use, although there are software mechanisms that disallow it. Disk locks, such as the one at SecurityKit.com, can be inserted into floppy drives on those computers that still have them to lock out other diskettes.

10. Protect your printers
You might not think about printers posing a security risk, but many of today’s printers store document contents in their own on-board memories. If a hacker steals the printer and accesses that memory, he or she may be able to make copies of recently printed documents. Printers, like servers and workstations that store important information, should be located in secure locations and bolted down so nobody can walk off with them.

Remember that network security starts at the physical level. All the firewalls in the world won’t stop an intruder who is able to gain physical access to your network and computers, so lock up as well as lock down.
