Wireless network security

Wireless-network security isn't a single issue. Businesses need to recognize that they are fighting attacks on several fronts. Many wireless-network threats are unique to the technology, including:
Threats:
Roaming Attackers: Attackers don't have to be physically located on a business's premises in order to access data on its wireless network. Criminals use network scanners, such as NetStumbler, with a laptop or other portable device to sniff out wireless networks from a moving vehicle — an activity called "wardriving." Performing the same task while walking down a street or through a business site is called "warwalking."
Rogue Access Points: A rouge access point is one that exists without the permission or knowledge of the wireless network's owner. Employees often install rogue access points to create hidden wireless networks that circumvent the installed security measures. Such stealth networks, while fundamentally innocuous, can create an unprotected gateway that serves as an open door to intruders.
The Evil Twin: Sometimes referred to as WiPhishing, an evil twin is a rogue access point that hides under a nearby network's name. The Evil Twin waits for an unsuspecting user to sign into the wrong access point and then steals the individual's network data or attacks the computer.
Network Resource Theft: Cheapskates like to get free Internet access from nearby wireless networks. Even if these individuals intend no direct harm, they still hijack network bandwidth to surf the Web and perform other online activities, draining network performance. More nefarious freeloaders will exploit the connection to send email from a company's domain or to download pirated content — exposing the host business to legal action.
Protection Methods
With wireless providing so many opportunities for attackers to enter and harm networks and business systems, it's no surprise that a wide array of security tools and techniques have arrived to help businesses secure their networks. Here are the top protection methods:
Firewalls: A strong network firewall can effectively block intruders trying to enter a business's network via a wireless device.
Security Standards: The first wireless-network security standard — WEP (Wired Equivalent Privacy) — was highly insecure and easily compromised. Newer specifications, such as WPA (Wifi Protected Access), WPA2 and IEEE 802.11i are much stronger security tools. Businesses with wireless networks should take full advantage of a least one of these technologies.
Encryption and Authentication: WPA, WPA2 and IEEE 802.11i supply built-in advanced encryption and authentication technologies. WPA2 and 802.11i both support AES (Advanced Encryption Standard), the specification used by many U.S. government agencies.
Vulnerability Scanning: Many attackers use network scanners that actively send messages to probe nearby access points for information, such as SSID (service set identifier) and MAC (machine access code) names and numbers. Businesses can use this same approach to uncover attacker-exploitable weaknesses in their wireless network, such as unsecured access points.
Lower the Power: Some wireless routers and access points allow users to lower the transmitter's power, reducing the device's coverage range. This is a useful way of limiting access to on-site users. Careful antenna positioning and placement can also help keep signals from "bleeding" into off-site locations.
Education: All employees should be trained in the proper use of wireless devices and instructed to report any unusual or suspicious activities they detect.

Flame virus warning

Microsoft issues Flame virus warning
Microsoft warned that a bug in Windows allowed PCs across the Middle East to become infected with the Flame virus and released a software fix to fight the espionage tool that surfaced last week.
Security experts said they were both surprised and impressed by the approach that the attackers had used, which was to disguise Flame as a legitimate program built by Microsoft. Kaspersky Lab, one of the researchers who helped to discover the Flame virus.
The creators of the virus obtained that certificate by manipulating a component of the Windows operating system known as terminal services licensing, or TS licensing, that is designed to authorize business customers to use advanced features of Windows. 
A bug in TS licensing allowed the hackers to use it to create fake certificates that identified Flame as being from Microsoft, Mike Reavey, a senior director with Microsoft's Security Response Center, said in a blog post. 
He feared that other hackers might be able to copy the technique to launch more widespread attacks with other types of viruses, Reavey said. 
"We continue to investigate this issue and will take any appropriate actions to help protect customers," Reavey said in the blog post. 
News of the Flame virus, which surfaced a week ago, generated headlines around the world as researchers said that technical evidence suggests it was built on behalf of the same nation or nations that commissioned the Stuxnet worm that attacked Iran's nuclear program in 2010. Researchers are still gathering information about the virus. 
Microsoft's warning is available at blogs.technet.com/b/msrc/

Change passwords on LinkedIn Now

If you have a LinkedIn account, now's a good time to change your password. Up to 6.5 million user accounts and encrypted passwords have reportedly been leaked and posted to a Russian hacker site.
LinkedIn hasn't confirmed the passwords have been stolen, but did confirm on its Twitter account they're looking into it. The leak comes off the news that LinkedIn's mobile apps transmit personal data, including meeting notes and calendar info in plain text. Regardless of whether the leak is confirmed or not, it's a good time to change your password. To do so, go straight to the LinkedIn Change Password page (you'll need to be logged in), enter a new, secure password, and click Change Password.
   LinkedIn has confirmed that some of the compromised passwords are LinkedIn accounts. If your password was compromised your account password has already been made invalid and you'll receive an email with instructions for how to reset your password (you can also double-check here: LeakedIn). If you use the same password and email address for other websites as you did with LinkedIn make sure you change those as well.

COMPUTER VIRUS

Every day as internet user we open lot of website and download many file like game,application software,songs,movie with this hope we are safe and secure.but my friends this is not true huge number of virus program gets download and install our pc and make us unsecure.Trojen virus is one of them.Lets gather some information about Trojen------
 Viruses work in many different ways. They are harmful to your computer and may even work to steal passwords and personal information. If you have a virus on your computer, make sure you get it taken care of immediately before it ruins your operating system and everything in it.
Trojan viruses steal passwords and other personal information. Trojans can also disable your current anti-virus or anti-spyware software, which makes it easier for other viruses to infect your computer along with the Trojan virus.
A remote access Trojan virus is often hidden in games or other small programs. Through remote access, a hacker will be able to get your personal information off of your computer just by doing a simple search, because they will have total control of your computer through a remote location.
Data sending Trojans work to gain your information through emails, credit card information, or even through your chat contact lists. A key logger can also be installed so that your every keystroke is recorded, which makes it easier for them to determine your credit card number, social security number, or any other number that you type into your computer.
A destructive Trojan is hard to detect, but it will work to destroy the files on your computer. Once this Trojan is installed, it will work to delete all of your information and files, where it will eventually work to delete your operating system. This type of Trojan is very hard to remove, and is often not even detected through normal anti-virus software.
If you suspect you may have a Trojan virus remove at as soon possible and disconnect internet connection.Install highly secured or updated antivirus and scan whole pc.If you found more than 50 file is infected then formate your pc and install new Os but remeber before doing any thing install antivirus first.
Good Luck !!!

Remote access Trojan

A remote access computer Trojan (RAT) designed to steal credit card details from hotel point-of-sale (PoS) applications is being sold on the underground forums, according to researchers from security firm Trusteer.
The researchers found an advertisement on a black market forum for a custom RAT designed to infect hotel front desk computers and steal customer credit card and billing information.
The seller was offering the computer Trojan, together with instructions on how to trick hotel front desk managers into installing it on their computers, for $280 (£175). The seller also claimed that the malware won't be detected by any antivirus program when it's delivered to the buyer.
Malware writers often repackage their malicious installers with new algorithms in order to evade signature-based antivirus detection, said Bogdan Botezatu, a senior e-threat analyst at antivirus vendor BitDefender.
The repackaged samples can then be delivered via email or instant messaging without being stopped at the network perimeter. However, if an antivirus product with strong heuristic and behavioural detection capabilities is running on the targeted systems, the malware should be blocked at execution time, Botezatu said.
The hotel RAT's seller specified in the ad that the malware doesn't collect card security numbers, also known as CVV or CID, but this doesn't necessarily make the rest of the stolen information less useful to cybercriminals.
Some merchants are allowed to charge cards without the CVV details, especially in the US, Botezatu said. However, even if that wasn't the case, the data can still be used to phish the security codes from the card owners themselves or to search for the codes in existing data dumps that resulted from older phishing attacks, he said.
Most remote access computer Trojans have the capability to take screenshots, record keystrokes, download/upload files and execute arbitrary code, which makes them suitable for many types of cybercriminal operations.
The hotel RAT advertisement included screenshots of a particular PoS application, but its functionality might not be restricted to that specific program.
"The strength of RATs is their generic nature - they can be used to attack many different applications in use by many industries,"
The fact that the RAT's creator decided to target the hospitality industry is consistent with a recently observed change in the focus of cybercriminals - an expansion from online banking attacks to attacks against PoS systems.

Credit Card Transaction Processing and Security

1. Cardholder. Cardholder is an authorized user of a credit or debit card.
2. Card issuer. Card issuers are financial institutions that are members of Visa and MasterCard, which issue payment cards on behalf of the two Credit Card Associations and contract with their cardholders for the terms of the repayment of transactions.
3. Acquiring bank. Acquiring banks (also called acquirers, processing banks or merchant banks) are financial institutions, members of Visa and MasterCard, that contract with merchants to enable them to accept debit and credit card payments for their products and services. They can also, and that is the case most of the time, contract with third parties to provide some of these services.
4. Payment processor. Payment processor is an organization that has contracted with an acquiring bank to provide merchants with card payment processing services on behalf of the acquirer. Payment processors must be registered with Visa and MasterCard and must identify on all of their marketing materials, including their websites, the name of their bank partner.
5. Merchant. Merchant is a business or a non-profit organization that has contracted with an acquiring bank or a merchant processor to accept card payments.
6. Credit Card Associations. The Credit Card Associations of Visa and MasterCard are member-owned associations of banks that govern the issuing of Visa and MasterCard cards and the acquiring of Visa and MasterCard card transactions. Both organizations have developed payment systems to facilitate the processing of transactions between member banks.
7. Service provider. A service provider can be any third party that provides a service used in the card payment transaction process: point-of-sale (POS) terminals, payment gateways, web hosting, SSL certificates, shopping carts, etc.

Login Security for Credit Card

Fraud and identity theft are not only a risk to your privacy, but a risk to your finances, so knowing what to look for can help prevent you from becoming a victim.
Fraudsters use ‘phishing’ or ‘spoofing’ tactics to get sensitive information from you. The deception usually involves a counterfeit website or email which looks similar to one you’d normally trust. Information you give on a phishing site could be used by criminals to access your account or use your identity fraudulently.

Login Userid and Password
After entering your username, you’ll be presented with the SiteKey™ image and phrase you selected when setting up your Online Card Services account - giving you reassurance that it’s really us.
SiteKey™ adds another layer of security, helping to prevent unauthorized access to your account and protecting your information from those who would use your identity for fraudulent purposes.
Address of Website
The address used by a counterfeit site may be very similar to our genuine website addresses. Look closely for spelling differences or the use of symbols, e.g. www.xyz.com, www.pqr@xyz.com or www.verify-xyz.com.
Hidden addresses - rest your cursor over a link in an email (but don't click on it) and a box will pop up showing you the link destination - do you recognize it as a legitimate address? If not it could suggest that the sender has something to hide.

Credit card

A credit card scam can come in many forms. For example, scammers may use spyware or some other scam to obtain your credit card details. A scammer might steal or trick you into telling them your security code (the three or four digit code on your card) and then make purchases over the internet or the telephone. If they know your PIN, they could get cash advances from an ATM using a ‘cloned’ credit card (where your details have been copied onto the magnetic strip of another card). credit card scam 

Of course, there is also a danger of someone using your credit card if it has been physically lost or stolen

Protect yourself from credit card scams
