Encryption For Internet Security

These days when no information seems safe online, people have been considering file and disk encryption. Sometimes, they don't even understand what it is. They just know it's a security measure they must take to ensure that they need not face the worst from being thieved of their data.

So what is encryption? Encryption is basically the process of presenting a piece on information in coded form. This means that human being will not be able to understand such information unless it is decoded or decrypted. Encryption is an effective way of protecting data traveling over the web and it is, in fact, one of the most used and reliable techniques in cryptography which is a body of scientific principles that promote safe communications.

Cryptogrpahy has a lot of ways but on the Internet, it it makes use of long series of numbers which can be decoded using certain algorithms. Some of these algorithms make use of only one key for encryption and decryption which means a key used for encrypting is the same key that will be used for decoding the data. In other cases, encryption uses one key and decryption will require another. The safer one to use is obviously the latter.

Generally, these keys are responsible for protecting the data that is contained in a piece of encrypted information. Internet browsers are currently using the Secure Sockets Layer (SSL) protocol to ensure that information entered by online customers are adequately protected as this travels from the customer's computer to the businessman's server. SSL encryption also relies on keys and this is the reason why before buying anything online, it is important that the site has an SSL certificate which means data entered into it will be traveling encrypted.

The rule is, the longer the key or the greater number of bits there are, the safer the encryption is. This is because it is generally easier to come up with different bit combinations and try them out. For example, if you have a 2-bit encryption, you can easily come up with four different combinations, try each one and eventually decrypt the information. However, with a 128-bit encryption, there are at least 309,485,009,821,345,068,724,781,056 combinations possible. According to experts, 128-bit encryption can be good enough for a period of ten years which is probably the amount of time it would take for all such combinations to be tried.

Internet security is mostly a matter of having a good understanding of the risks involved as well as knowing what must be done to reduce the risks. In terms of general Internet safety, one can rely on an IP changing software which is a program designed to allow a user to surf the Internet with his IP address hidden.

Remember that an IP address is a computer's unique identifier when it connects with any other computer on the Internet. This means that whatever a hacker can do, he can do it because he knows his victim's IP address. Naturally, when you hide your IP, you're safe from hackers. Thus, with an IP changer alone, you can be assured of significant Internet threat protection.

Why Online Backup is Important - Safeguard Your Data on the Internet

Information is what makes the world go round. In the business world, any organization stores thousands or millions of data everyday for the use in their venture. Sales receipts, pricelist, manifests, and portfolios -- every single data is stored in a database for various uses. What do you think would happen if your precious data is suddenly wiped out from your storage? Let me introduce to you the concept of online backup.

Online Storage

The Internet is not only for the function of disseminating information to every individual in the planet. Today, those who have access to the Internet is capable of utilizing online storage sites to safeguard their files and having access to it wherever they go. The concept of online backup is simple -- store data that can be accessed from any computer console at your disposal.

Safeguard Data

Database backup offsite has its own advantages and disadvantages, but the benefits tend to outweigh the possible drawbacks that come with it. For starters, you can easily upload any form of data to your online servers with ease. You can backup your files through FTP, or Web-based environment for data upload and download.

Benefits

Online backup offers every individual the convenience of having access to important data from any computer console available. Let's take your Webmail for example, you can access your mails from any computer -- all you need to do is to login to your account and your done. Same is with the case of file backup online. You just need to login to your account, utilize built-in applications for uploading files, that's it!

Also, online backup is your last resort in case of emergencies -- like someone accidentally wiped out your entire database on your company's computer. You need not worry sine you have all the information from your latest backup and you can immediately download it to your computer to restore organization functions without having to worry too much about it.

Keep in mind, however, that human initiative is essential for a successful utilization of file backup online. Set a date or time for a routine backup to ensure that restoration of these relevant data is up-to-date. It might also be best to limit people who have access to your backup to avoid tampering.

Online backup is a necessity in today's business. Trusting too much on your private servers might lead to unrecoverable loss later on when you don't have a backup online to restore company operations.

Keep Your PC Safe - Internet Security For the Home User

As the number of cable modems and Wi-Fi networks increases, internet security is becoming more of an issue. You may think that your Internet connection is safe from unwelcome and unwanted intrusion by hackers, but there are some things you can do to improve your security levels to stop hackers gaining access to your personal details, bank account numbers and passwords.

The reason that Internet security is becoming more of an issue now is that people are spending longer connected to the Internet. And unless that pathway is protected by high level security, the hackers will have more opportunities to find a way in. Hijacked machines (often known as zombies and forming part of botnets) are valuable to fraudsters and spammers. The trick is to beat the hackers at their own game.

There are three aspects of home Internet protection, sometimes referred to as the 'holy trinity'.

Personal firewall/intrusion detection

These are the firewalls that often come with your operating system. In older operating systems such as Windows 95 and 98, these systems have virtually no inbuilt security. Because these systems have now been superseded by more up to date software, it is advisable that if you are still operating Win95 or 98 to upgrade to a system that is supported by a Microsoft inbuilt firewall.

All versions of Vista, XP and 2000 are still supported by Microsoft and have inclusive firewall protection. For an additional layer of security, external firewall programs can be incorporated into your operating system as simply as downloading any other piece of software. It is advisable to talk to an expert, however, as some firewalls may not be compatible with your operating system and you may encounter run conflicts that could affect other aspects of your system.

The most popular free downloadable firewall is Zone Alarm, although for comprehensive coverage, Zone Alarm Pro is probably a better option. You can also set your Internet security levels to 'high' on your operating system if you are going to be on the Internet for prolonged periods.

Anti-spyware software

Spyware is software that covertly gathers user information through the user's Internet connection without his or her knowledge. That information is then passed to a third party (the hacker or fraudster) and suddenly your secure system isn't quite as secure as you thought it was. There are countless pieces of embedded software (often also known as 'malware') that piggyback onto downloads and install themselves into your operating system. These include BHOs (Browser Helper Objects) which hijack your browser and take it to their 'chosen' site whether you want to go there or not. Although annoying, these don't do any real damage. However, other spyware can count keystrokes and relay these back to hackers who, from this data, can uncover passwords and other information such as account numbers. Anti-spyware software stops this malware from infiltrating your computer and leaving your important information exposed.

Anti-virus software

A virus can devastate a computer. Designed to cause maximum damage to your data, viruses are created to cause mayhem and have no other purpose other than that. Anti-virus software is essential, particularly if you are using the Internet for long periods of time, and the best option is to include a package such as McAfee VirusScan in your operating system. Ensure that you update this program regularly (you will receive prompts from your computer on start-up).

No piece of anti-virus or spyware software can cover all threats, so it's a good idea to keep an eye out for updates and to combine several systems to cover your bases. There are also some things you can do for yourself when online to keep your PC and your personal details safe:

• Never open email attachments if you do not know who the email has come from, or even from friends. This is the easiest way to allow a virus to access your system.
• Avoid downloading files from sites you are not familiar with.
• Ensure that your security protocol is set to 'high' if you are going to be online for any length of time
• No bank will ever ask for your details via email. Any that do are scams and should be immediately deleted without responding and your bank notified of the scam attempt.
• If something looks suspicious (poor spelling, bad graphics), then trust your instincts - it probably is a bogus email or phishing attempt to get access to your personal details
• If you have a wireless network in your home, ensure that it is password protected.
• Never have the same password for all your sites.

With a little thought and preparation, you can keep your home PC safe from outside attacks and your details out of the hands of fraudsters.

DDoS Attack Hits Amazon Cloud Customer Hard

UPDATE: updated to clarify that the downtime was isolated to the single customer, and to include comments from Amazon Web Services.

(WEB HOST INDUSTRY REVIEW) -- As has been reported in several sources this week, including this report from The Register, a customer of Amazon’s cloud computing service - Bitbucket (www.bitbucket.org), a web-based code hosting service that uses both EC2 and the Amazon’s Elastic Block Storage - reported 19 hours of downtime as a result of a DDoS attack.

The disruption, as most of the reports have mentioned, is certain to raise questions about both the resiliance and stability of cloud hosting solutions, as well as invite scrutiny into the quality of Amazon’s response to customer situations like this one.

In an email, Amazon Web Services public relations manager Kay Kinton writes "The customer’s Amazon EC2 instance was receiving a very large amount of network traffic. This large flood of traffic exceeded the networking of the customer’s single Amazon EC2 instance and caused performance to degrade on all network operations for that instance (including access to the EBS volume). Once we properly diagnosed the problem, we worked with the customer to put measures in place to help mitigate the unwanted traffic they were receiving. We have continued to work with the customer to apply network filtering techniques which have kept their site functioning properly."

Bitbucket operator Jesper Nøhr spent a great deal of energy venting his frustrations about the situation via Twitter over the weekend and on Monday. He also published a detailed account of the outage timeline on the company’s blog.

He says in the post that, while he was advised not to reveal the source of the outage (according to The Register, because Amazon felt revealing the attack might give future attackers fuel for designing new means of attacking the service), he believed he owed it to customers to explain what went wrong.

“We were attacked. Bigtime,” he wrote. “We had a massive flood of UDP packets coming in to our IP, basically eating away all bandwidth to the box. This explains why we couldn’t read with any sort of acceptable speed from our EBS, as that is done over the network. So, basically a massive-scale DDOS. That’s nice.”

Nøhr’s blog post, and much of the discussion that has flowed from the incident, is more a look at Amazon’s response, and a debate about the nature of customer service than an investigation into the technical issues at play. His post concludes by saying Bitbucket is taking measures to ensure an outage of this kind won’t happen again, and that those measures might include moving to a new hosting provider.

In the final analysis, he doesn’t come down too hard on Amazon, demonstrating that the company devoted a lot of support attention to his cause after a frustrating (and exceedingly long) preliminary period – about 10 hours.

After the service was originally restored, Bitbucket reportedly suffered two further attacks, Sunday morning and early Monday.

The technical question seems to be how an attack using external traffic was able to disrupt the connection between Bitbucket’s EC2 and EBS resources, which one might reasonably consider an “internal” network connection, and why Amazon didn’t have the means in place to more quickly identify the outage as the result of a DDoS attack.

Kinton points out that AWS may have to do more work to help educate customers on the availability of measures to mitigate the impact of unexpected spikes in traffic.

"We are working to make sure we learn from this and continue to improve the speed with which we and our customers can diagnose issues like this," she says. "We will also provide additional guidance to our customers on how they can better detect this sort of problem and use existing features of EC2 to run a highly scalable and available website. These features include taking advantage of EC2’s scale-out ability to run multiple instances in multiple availability zones and regions, the Elastic Load Balancing feature which helps users filter and balance traffic among their instances and the Auto-Scaling feature which allows users to scale in response to changes in customer traffic."

In the comment section of the Bitbucket blog post, Nøhr wrote that he wouldn’t answer many of the technical questions posted in the comments, but that the company’s system admins “are writing a follow-up post outlining some more meaty details with numbers and graphs.”

The Assclown Offensive: How to Enrage the Church of Scientology

In the evening of January 15, 2008, a 31-year-old tech consultant named Gregg Housh sat down at the computer and paid a visit to one of his favorite Web sites, the message board known as 4chan. Like most of the 5.9 million people who visit the site every month, Housh was looking for a few cheap laughs. Filled with hundreds of thousands of brief, anonymous messages and crude graphics uploaded by the site's mostly male, mostly twentysomething users, 4chan is a fountainhead of twisted, scatological, absurd, and sometimes brilliant low-brow humor. It was the source of the lolcat craze (affixing captions like "I Can Has Cheezburger?" to photos of felines), the rickrolling phenomenon (tricking people into clicking on links to Rick Astley's ghastly "Never Gonna Give You Up" music video), and other classic time-wasting Internet memes. In short, while there are many online places where you can educate yourself, seek the truth, and contemplate the world's injustices and strive to right them, 4chan is not one of them.

Yet today, Housh found 4chan grappling with an injustice no Internet-humor fan could ignore. Days earlier, a nine-minute video excerpt of an interview with Tom Cruise had appeared unauthorized on YouTube and other Web sites. Produced by the Church of Scientology, the clip showed Cruise declaring himself and his co-religionists to be, among other remarkable things, the "only ones who can help" at an accident site. For the online wiseasses of the world, the clip was a heaven-sent extra helping of the weirdness Tom Cruise famously showed on Oprah. But then, suddenly, it was gone: Scientologists had sent takedown notices to sites hosting the video, effectively wiping it from the Web.

Housh and other channers knew that Scientology had a long history of using copyright law to silence Internet-based critics. But this time, maybe because the church was stifling not just unflattering content but potential comedy gold, the tactic seemed to inflame the chortling masses. That evening, Housh logged in to an IRC channel frequented by like-minded chuckleheads and started talking with five others about the Cruise video. There was a sense that something must be done, but what? One of them logged out and posted a call to action on 4chan and some similar sites. By the middle of the night, 30 people had joined the chat. Within a couple of days, a consensus emerged: They would take down the main Scientology Web site with a massive distributed denial-of-service attack, or DDoS.

By the time the attacks started on January 18, Housh and many of the now 200 others on the chat channel were devoting every spare moment to the cause: "We were like, OK, we have 24 hours today. None of us need to sleep. Get your caffeine. What's the next step?"

Someone suggested they create a press release. Housh and four others broke off into a side channel to work on it while the DDoS attacks unfolded. They figured they should explain the goals of their spontaneous uprising, but what exactly were those goals? "We had no fricking clue what we were doing," Housh says. "We didn't mean to do it in the first place." They were still more of a riot than a movement—a faceless, leaderless mob growing daily as new adherents flocked in. None of them knew one another, even by pseudonyms, since as a rule there was only one username throughout the community. In fact, it was a standing in-joke on 4chan and related sites that their collective output was the product of a single hive-mind entity, known by that same username: Anonymous.

Instead of a press release, Housh and the others made a video introduction in the name and voice of the hive mind itself. Thrown together in a few days of furious collaboration, it appeared on YouTube on January 21, titled "Message to Scientology."

"Hello, leaders of Scientology. We are Anonymous," the clip began in a robotic, software-generated voice-over accompanied by stock footage of clouds rolling over desolate cityscapes. "Your campaigns of misinformation, your suppression of dissent, your litigious nature: All of these things have caught our eye," the voice explained. "For the good of your followers, for the good of mankind—and for our own enjoyment—we shall proceed to expel you from the Internet and systematically dismantle the Church of Scientology in its present form." The message ended, as it had begun, on a pitch-perfect note of sci-fi comic book menace: "We are Legion," the robot voice intoned. "We do not forgive. We do not forget. Expect us."

Website Security - Be Hacker Proof!

At first glance, online shopping seems easy as 123 because of how easy it is to choose, compare and purchase different products with the help of search engines. According to a survey of American online shoppers, 41% abandon their carts once they face difficulty in the transaction process. This only indicates that the story doesn't always have a happy ending. Some online shoppers do encounter difficulties, confusion and misleading tactics that make them discontinue the shopping or subscription process. Can all this be blamed to a weak website security?

If you are online merchant, you want to avoid your potential sale from turning into thin air. Surprisingly, it is not other e-commerce businesses that you should feel threatened about- even more if you know for yourself that you sell top notch products or services. It is those attackers trying to find a vulnerable spot in your website security that you should be careful of. 95% of cyber attacks are targeted to banks and businesses processing credit cards. And if you have no protection, then you have higher chances of being hacked.

Cyber crime is rising rapidly and it has become a weapon of destruction because in the year 2008 alone, the loss due to cyber crimes has reached $1 trillion. What's even more alarming is the fact that tracing these cyber criminals is almost close to impossible. Even government institutions have fallen prey to hackers, and sad to say, due lack of evidence and difficulty in tracing, they haven't had prosecuted almost any of the guilty party.

Computers were invented out of necessity and we store everything in it! This is followed by the creation of internet -a real world where we buy, sell, exchange goods and services. Are you a 100% sure that information is securely saved on your computer network and website?

Take note that hackers are privacy invaders and will try incessantly to steal your that identity and hard earned income. Cyber attackers are masters when it comes to sophisticated technology. They can insert viruses and malicious files into your system without you even knowing it. The truth is having only anti- virus software can be a false sense of security. If you really want to prevent your business from becoming a statistic in cyber crime damages, then be educated about website security. You'll have higher chances of beating the bad guys if you are aware of how they play the game of fraud.

You can only be prepared if you know what you are dealing with. Here are some cyber attacks you may not have heard of:

1. Phishing- method to steal credit card information, passwords and other important information in forms of suspicious links, and emails of spoofed websites.

2. Clickjacking - this is one of the new and most dangerous threats because there isn't any effective solution for this problem yet. So what hackers and spammers do is that they hide a malicious content under the cover of legitimate buttons or clickable items in the website. For example, you clicked 'enter' into a website but instead the hacker directed the click you made into downloading viruses. They can also create spoofs of legitimate websites, where they steal credit card information entered by shoppers.

Online shoppers face more risk of fraud than those who do physical shopping. They might thought that they have purchased real goods from a legitimate merchant, but it can be possible they were actually misled. Online merchants also face the possibility of being hacked of names, addresses and credit card information. It is no surprise that for this reason, e-commerce businesses come and go. Having no website security is like having no burglar alarm on your property. You may wake up one day and everything has been taken away.

Hackers don't only target only large businesses. In fact, they easily find unprotected systems which are mostly small to medium businesses. According to hacker safe, 75% of e-commerce is not secure. Isn't it a disgrace to be a part of that statistic? There are many ways to get started with website security. So go ahead and get started.

1. Get covered with the basics. So install at the same time: a firewall system, anti-virus program and anti spy-ware program.

2. Get trust seals. This works both ways- it increases consumer confidence thus increasing sales and secures your website from vulnerabilities that hackers can take advantage of.

3. Get a consultant. If you have a budget and you can't handle it on your own, get a consultant to take care of your system and network. They too can make professional recommendations on ways how to secure your network.
