If your a newbie in Internet security,you have come to the right place.The following is information on some common terms used in Internet security.So,next time you don't have to scratch your head when someone uses these on you or when you use it.
Firewall: is a system acts that acts as a barrier between your computer network and the internet.A firewall controls the flow of information according to security policies.
Hacker: can be anyone specializing in accessing computer based systems for illegal purposes or just for fun of it.
IP spoofing: is an attempt to access your system by pretending like another system.This is done by setting up a system with an IP address that you normally trust.
Sniffing: is the spying on electronic transmissions to access data. This mostly occurs in privately owned LAN networks connected to the web.
Trojan Horse: a program pretending like useful software,while its actual strategy is to access,steal or destroy user data and access authorization.Apart from destroying information, Trojan's can also create back door on your system for stealing confidential information.
Virus: is a program that attaches itself to a programmer file. This allows it to spread across networks and cause damage to software and hardware. To operate, viruses require execution of the attached file.
Worm: A worm is almost similar to a virus, except that it doesn't need the execution of any executable file to get activated. It can also replicate itself as it travels across networks...

What is SPAM & How To Protect An Email Account From SPAM ?

Posted On // Leave a Comment
Most of us get SPAM every day. Some of us get more and some little. Even a newly created email account will begin to receive spam just after a few days of its creation. Many times we wonder where these spam come from and why? But this question remains unanswered within us. So in this post I will try my best to give every possible information about the spam and will also tell you about how to combat spam.
What is SPAM?
Spam
 is the abuse of electronic messaging systems (including most broadcast media, digital delivery systems) to send unsolicited bulk messages indiscriminately. Most widely recognized form of spam is email spam.
Where do these SPAM come from?These spam come only from spammers and never from a legitimate user or a company. These spammers send a single email to hundreds (some times thousands or millions) of email addresses at a time. They either send it manually or use spambots to automate the process of spamming.
Why do spammers SPAM?The main goal of spammers is to send the spam (unsolicited bulk messages) to as many people as possible in order to make profit. For example, John builds a small website to sell an ebook which gives information about weight loss. In order to make sales he needs publicity for his website. Instead of spending money on advertising, John decides to create an email which contains information about his site along with it’s link and send this email to say 100 email addresses in his contact list. If 1 person out of hundred buy this book john gets $10. What if he sends this email to 1000s of email addresses. He gets $100. Imagine, if he sends this email to 1 Million email addresses he gets $100000.
Now I hope you understood the idea behind spamming. So in order to make money, spammers send their advertising emails to as many people as possible without respecting the recipient’s privacy.
From where do SPAMmers get my email address?On the Internet there exist many sites who collect the email IDs of people and sell them to spammers in bulk. Most often, people sign up for monthly newsletters and take up surveys. This is the time where these scam sites get their email addresses. Also many spammers collect email addresses by using spambots. These spambots collect email addresses from the Internet in order to build mailing lists. Such spambots are web crawlers that can gather email addresses from Web sites, newsgroups, forums, special-interest group (SIG) postings, and chat-room conversations.
Spammers also use the trick of creating Hoax Emails for gathering a huge list of email IDs. For example, a spammer sends a hoax email which says “Forward this Message to Help Severely Burned Child”This email claims that 11 cents will be donated to the child’s family every time the message is sent to others. Most of the people believe this and start forwarding this hoax email to all of the IDs in their contact list. In this way the email spreads rapidly and eventually when it reaches the creator (spammer), the spammer gets a huge list of valid email addresses in the email header. When you get these kind of hoax emails, you can see for yourself in the email header which contains a huge list of email addresses of all those people to whom the email is being forwarded to. This is one of the effective methods used by spammers to gather email addresses.
Is SPAMming legal?Spamming is completely illegal. Yet it is really difficult to stop spammers from spamming since they keep moving from one hosting company to another after getting banned. This makes it practically impossible to catch spammers and prosecute them.
How to protect my email account from getting SPAMmed?The following methods can be used to combat email spam.
1. Use spam filters for your email account. If you’re using email services like Gmail, Yahoo, Hotmail etc. then spam filters are used by defaut. Each spam filter has it’s algorithm to detect spam emails and will automatically move them to SPAM folder. This keeps your inbox free from spam. However some spam emails become successful to make their way into the inbox by successfully bypassing the filters.
2. Do not post your email address in public forums, user comments and chat-rooms. Give your email address only to trustworthy websites while signing up for newsletters.
3. While taking up online surveys and filling up feedback forms, it is better not to give your personal email address. Instead singup for a dummy email account and use this for surveys and feedback forms.
4. While posting your contact email address on your website use this format: emailaddress [at] yoursite.com instead of emailaddress@yoursite.com. This protects your email address from being indexed by spambots.
5. Do not respond to hoax messages. When you receive a hoax email, avoid forwarding it to your friends. Examples of hoax messages can be found at www.hoax-slayer.com. If you really want to forward it to your friends, make sure that you use “Bcc” (blind certified copy) option to send the email. This will hide all the email IDs to which the mail is forwarded to.

Hurricane warnings for Mexico, US as Alex grows

Posted On // Leave a Comment
A National Oceanic and Atmospheric Administration satelite image shows Tropical Depression Alex. On its …


VILLAHERMOSA, Mexico – Hurricane warnings were posted Monday for a stretch of Gulf coast in southern Texas and northern Mexico as Tropical Storm Alex gained strength and appeared on track to become a hurricane before it makes landfall later this week.
Forecasters said the storm's path could push oil from the huge Gulf oil spill farther inland and disrupt cleanup efforts.
Alex was swirling through the Gulf of Mexico with winds near 65 mph (100 kph) Monday night on a path that would take it very near the Mexico-U.S. border sometime late Wednesday, said the U.S. National Hurricane Center in Miami, Florida. The storm is expected to become a hurricane Tuesday.
Conditions late Monday afternoon led the center to believe the storm will be less powerful than previously predicted but still likely to gain hurricane strength, forecaster Todd Kimberlain said.
Tropical storm-force winds extended up to 70 miles (110 kilometers) from the storm's center, and Alex was moving toward the north near 5 mph (7 kph).
Heavy rains in Mexico's southern Gulf coast state of Tabasco forced the evacuation of about 300 families from communities near the Usumacinta river.
The hurricane warnings extend from Baffin Bay, Texas south across the mouth of the Rio Grande river to La Cruz, Mexico.
The tropical storm's center wasn't expected to approach the area of the oil spill off Louisiana's coast, said Stacy Stewart, senior hurricane specialist at the National Hurricane Center. But Alex's outer wind field could push oil from the spill farther inland and hinder operations in the area, Stewart said early Monday.
The hurricane center said Alex is expected to produce 5 to 10 inches of rainfall over portions of northeastern Mexico and southern Texas over the next few days. It warned of a dangerous storm surge along the coast near and to the north of where the storm makes landfall.
Alex caused flooding and mudslides that left at least five people dead in Central America over the weekend, though Belize and Mexico's Yucatan Peninsula appeared largely unscathed.
It made landfall in Belize on Saturday night as a tropical storm and weakened into a depression on Sunday as it crossed the Yucatan Peninsula.
Mexico's northern Gulf coast braced for heavy rains, and forecasters said precipitation from Alex would keep falling on southern Mexico and Guatemala until Tuesday, raising the possibility of life-threatening floods and mudslides.
"It is a fact we are going to get very heavy rains," said Gov. Fidel Herrera of the Gulf coast state of Veracruz.
On Sunday, heavy rains prompted a landslide in northwestern Guatemala that dislodged a large rock outcropping, killing two men who had taken shelter from the storm underneath, according to the national disaster-response agency.
In El Salvador, Civil Protection chief Jorge Melendez said three people were swept away by rivers that jumped their banks. About 500 people were evacuated from their homes.
There were no immediate reports of damage to Mexico's resort-studded Caribbean coast.
When Alex became the first named storm of the Atlantic hurricane season, officials immediately worried what effect it could have on efforts to contain the millions of gallons of crude spewing into the northeastern part of the Gulf.
A cap has been placed over the blown-out undersea well, directing some of the oil to a surface ship where it is being collected or burned. Other ships are drilling two relief wells, projected to be done by August, which are considered the best hope to stop the leak.
Alex was centered about 505 miles (810 kms) southeast of Brownsville, Texas, on Monday evening. Its rains could reach Veracruz and the border state of Tamaulipas late Tuesday or Wednesday, the Hurricane Center said.

Analysts say Apple's iPhone 4 parts cost $187.51

Posted On // Leave a Comment
SEATTLE – Apple Inc.'s new iPhone 4 costs almost $20 more to make than its predecessor, the iPhone 3GS, but the device will still help the company continue to rack up high profits, the research group iSuppli said Monday.
The iPhone 4 went on sale June 24. After taking this latest Apple gadget apart and identifying the components, iSuppli estimated the cost of the parts totals $187.51. That's more than the $170.80 iSuppli estimates for the cost of the materials inside the iPhone 3GS, Apple's last-generation smart phone.
The estimates don't include manufacturing, software, marketing and other costs.
The priciest part of the iPhone 4 is the new, higher-resolution LCD screen, which iSuppli estimates carries a cost of $28.50. Flash memory, which has been in short supply, costs $27. Apple's processor, which was manufactured by Samsung, according to iSuppli, costs $10.75, and the capacitive touch screen costs $10.
Apple's iPhones cost consumers $199 or $299 with a two-year wireless contract in the U.S., but such low prices as those are heavily subsidized by the wireless carriers.
Despite the major design overhaul Apple gave the iPhone, the gadget maker "will be able to maintain the prodigious margins that have allowed it to build up a colossal cash reserve," said Kevin Keller, an iSuppli analyst, in a statement.

Apple sells more than 1.7M iPhones in 3 days

Posted On // Leave a Comment
In this June 24, 2010 file photo, Duane Davis, left, learns about the new features of the Apple …


NEW YORK – Apple Inc. said Monday that it sold more than 1.7 million units of its new iPhone model in the first three days, making it the most successful product launch in the company's history from the standpoint of sales.
The iPhone 4 went on sale Thursday in the U.S., Britain, France, Germany and Japan. High demand for the model caused shortages and unruly crowds at some stores.
"This is the most successful product launch in Apple's history," said Steve Jobs, Apple's CEO. "Even so, we apologize to those customers who were turned away because we did not have enough supply."
Some stores sold out within hours. Analysts have said Apple is having a hard time procuring enough parts for the phone, such as its new higher-resolution screen. Apple has said the white iPhone it plans to produce has been more challenging than expected and won't be available until late July. Only black models went on sale Thursday.
Apple sold more than 1 million units in the first three days when it launched last year's model, the 3GS. Canada, Italy, Spain and Switzerland were then among the launch countries, but Japan was not.
Apart from the sharper screen, the iPhone 4 features a slimmer body and faster processor than the previous model, among other changes.
Shares of the Cupertino, Calif.-based Apple rose $1.60, or 0.6 percent, to $268.30 in trading Monday.

10 alleged Russian secret agents arrested in US

Posted On // Leave a Comment
 AP – In this courtroom sketch, Anna Chapman, left, Vicky Pelaez, second from left, the defendant known as …

 WASHINGTON – The FBI has arrested 10 people who allegedly spied for Russia for up to a decade — posing as innocent civilians while trying to infiltrate U.S. policymaking circles and learn about U.S. weapons, diplomatic strategy and political developments.
An 11th defendant — a man accused of delivering money to the agents — remains at large.
There was no clue in the court papers unsealed Monday about how successful the agents had been, but they were alleged to have been long-term, deep cover spies. Among them were four couples living in suburbs of New York, Washington and Boston. One woman was a reporter and editor for a prominent Spanish-language newspaper in New York whom the FBI says it videotaped contacting a Russian official in 2000 in Latin America.
These deep-cover agents are the hardest spies for the FBI to catch and are dubbed "illegals" in the intelligence world because they take civilian jobs with no visible connection to a foreign government, rather than operating from government jobs inside Russian embassies and military missions. In this case, they were spread out and seeking a wide swath of information.
The FBI said it intercepted a message from Moscow Center, headquarters of Russia's intelligence service, the SVR, to two of the defendants describing their main mission as "to search and develop ties in policymaking circles in US." Intercepted messages showed they were asked to learn about a wide range of topics, including nuclear weapons, U.S. arms control positions, Iran, White House rumors, CIA leadership turnover, the last presidential election, Congress and the political parties.
The blockbuster series of arrests of purported deep cover agents following a multiyear FBI investigation could rival the bureau's famous capture of Soviet Col. Rudolf Abel in 1957 in New York.
Also a deep cover agent, Abel was ultimately swapped to the Soviet Union for downed U-2 spy pilot Francis Gary Powers in 1962.
The court papers also described a new high-tech spy-to-spy communications system used by the defendants: short-range wireless communications between laptop computers — a modern supplement for the old-style dead drop in a remote area, high-speed burst radio transmission or the hollowed-out nickels used by Abel to conceal and deliver microfilm.
But there was no lack of Cold War spycraft. According to the court papers, the alleged agents used invisible ink, stayed in touch with Moscow Center through coded bursts of data sent by a radio transmitter, used innocent-looking "brush" encounters to pass messages in public, hid encrypted data in public images and relied on fake identities and false travel documents.
On Saturday, an undercover FBI agent in New York and another in Washington, both posing as Russian agents, met with two of the defendants, Anna Chapman at a New York restaurant and Mikhail Semenko on a Washington street corner blocks from the White House. The FBI undercover agents gave each an espionage-related delivery to make. Court papers indicated Semenko made the delivery as instructed, but apparently Chapman did not.
The court papers cited numerous communications intercepted by the FBI that spelled out what information was sought.
The timing of the arrests was notable given the efforts by Presidents Barack Obama and Dmitry Medvedev to "reset" U.S.-Russia relations. The two leaders met last week at the White House after Medvedev visited high-tech firms in California's Silicon Valley, and both attended the G-8, G-20 meetings over the weekend in Canada.
Intelligence on Obama's foreign policy, particularly toward Russia, appears to have been a top priority.
In spring 2009, the documents say, alleged conspirators, Richard and Cynthia Murphy, who lived in New Jersey, were asked for information about Obama's impending trip to Russia that summer, the U.S. negotiating position on the START arms reduction treaty as well as Afghanistan and the approach Washington would take in dealing with Iran's suspect nuclear program, the documents said. They were also asked to send background on U.S. officials traveling with Obama or involved in foreign policy.
"Try to outline their views and most important Obama's goals (sic) which he expects to achieve during summit in July and how does his team plan to do it (arguments, provisions, means of persuasion to 'lure' (Russia) into cooperation in US interests," Moscow asked.
Moscow wanted reports "which should reflect approaches and ideas of" four sub-Cabinet U.S. foreign policy officials.
One intercepted message said Cynthia Murphy, "had several work-related personal meetings with" a man the court papers describe as a prominent New York-based financier active in politics.
In response, Moscow Center described the man as a very interesting target and urged the defendants to "try to build up little by little relations. ... Maybe he can provide" Murphy "with remarks re US foreign policy, 'roumors' about White house internal 'kitchen,' invite her to venues (to major political party HQ in NYC, for instance. ... In short, consider carefully all options in regard" to the financier."
Each of the 10 was charged with conspiracy to act as an agent of a foreign government without notifying the U.S. attorney general, which carries a maximum penalty of five years in prison. Two criminal complaints outlining the charges were filed in U.S. District Court for the southern district of New York.
Nine of the defendants were charged with conspiracy to commit money laundering, which carries a maximum 20 years in prison.
The papers allege the defendants' spying has been going on for years.
One defendant in Massachusetts made contact in 2004 with an unidentified man who worked at a U.S. government research facility.
"He works on issues of strategic planning related to nuclear weapon development," the defendant's intelligence report said.
The defendant "had conversations with him about research programs on small yield high penetration nuclear warheads recently authorized by US Congress (nuclear 'bunker-buster' warheads)," according to the report.
One message back to Moscow from the defendants focused on turnover at the top level of the CIA and the 2008 U.S. presidential election. The information was described as having been received in private conversation with, among others, a former legislative counsel for Congress. The court papers deleted the name of the counsel.
In the papers, FBI agents said the defendants communicated with alleged Russian agents using mobile wireless transmissions between laptops computers, which has not previously been described in espionage cases brought here: They established a short-range wireless network between laptop computers of the agents and sent encrypted messages between the computers while they were close to each other.
FBI agents arrested the defendants known as Richard Murphy and Cynthia Murphy at their Montclair, N.J., residence.
A neighbor, Louise Shallcross, 44, said she often saw Richard Murphy at the school bus stop.
"We were all very excited to have a stay-at-home dad move in," Shallcross said.
Three other defendants also appeared in federal court in Manhattan — Vicky Pelaez and a defendant known as "Juan Lazaro," who were arrested at their Yonkers, N.Y., residence and Anna Chapman, arrested in Manhattan on Sunday.
Richard and Cynthia Murphy, Juan Lazaro, Vicky Pelaez and Anna Chapman were held without bail. The defendants — most dressed in casual clothes like blue jeans, shorts and T-shirts — answered "Yes," when asked if they understood the charges. None entered a plea.
"The evidence is truly, truly overwhelming," said Assistant U.S. Attorney Michael Farbiarz. Another hearing was set for Thursday.
Waldo Mariscal, Pelaez' son, said in federal court that his mother was innocent. "This is a farce," he said. "We don't know the other people."
Pelaez is a Peruvian-born reporter and editor and worked for several years for El Diario/La Prensa, one of the country's best-known Spanish-language newspapers. She is best known for her opinion columns, which often criticize the U.S. government.
A senior editor at the newspaper confirmed the arrest but declined to comment on the allegations. The editor, who spoke on the condition of anonymity, was not authorized to speak for the company.
In January 2000, Pelaez was videotaped meeting with a Russian government official at a public park in the South American nation, where she received a bag from the official, according to one complaint.
According to one of the complaints, Lazaro and Pelaez discussed plans to pass covert messages with invisible ink to Russian officials during another trip Pelaez took to South America.
An attorney for Chapman, Robert Baum, argued that the allegations were exaggerated and that his client deserved bail.
"This is not a case that raises issues of security of the United States," he said.
The prosecutor countered that she was a flight risk, calling her a highly trained "Russian agent" who is "a practiced deceiver."
Two other defendants, known as Michael Zottoli and Patricia Mills, were arrested at their Arlington, Va., residence. Also arrested at an Arlington, Va., residence was Mikhail Semenko.
Zottoli, Mills and Semenko appeared before U.S. Magistrate Theresa Buchanan early Monday afternoon in Alexandria, Va., according to the U.S. attorney's office. The hearing was closed because the case had not yet been unsealed in New York. The three did not have attorneys at the hearing, U.S. attorney spokesman Peter Carr said.
In Arlington, where Zottoli and Mills lived in a ninth-floor apartment, next-door neighbor Celest Allred said her guess had been that "they were Russian, because they had Russian accents."
Two defendants known as Donald Howard Heathfield and Tracey Lee Ann Foley were arrested at their Cambridge, Mass., residence Sunday. They appeared briefly in Boston federal court on Monday afternoon. A detention hearing was set for Thursday.
In Moscow, calls to the Foreign Ministry and the Foreign Intelligence Service (SVR) were not answered early Tuesday.
The two most prominent cases involving the SVR in the past decade may have been those of Robert Hanssen, the FBI counterintelligence agent who was convicted of passing along secrets to the agency, and Sergei Tretyakov, deputy head of intelligence at Russia's U.N. mission in 1995-2000.
Tretyakov, who defected in 2000, claimed in a 2008 book that his agents helped the Russian government steal nearly $500 million from the U.N.'s oil-for-food program in Iraq before the fall of Saddam Hussein. He said he oversaw an operation that helped Saddam's regime manipulate the price of Iraqi oil sold under the program and allowed Russia to skim profits.
