Pollution on the World Wide Web

Mon, 12 Jul 2010 11:45:55 -0400

There are so many virtual versions of things found in the real world. There is the virtual post office, the ubiquitous email. We can now telecommute as opposed to actually getting into a car and driving to an office, which would be pointless as there are now virtual offices. We can have conferences virtually thanks to programs like Skype. We even have virtual showrooms of actual stores where we can peruse and shop for items without leaving our homes.

This is all very fine and very, very convenient - at least for those of us who are connected. But like all progress, like all advancement there is a hidden cost. Pollution. There is pollution in the internet. Virtual pollution if you will.

The reason no one talks about it is because unlike most kinds of pollution, this pollution cannot be smelled or heard or seen. It doesn't intrude into our space, even our virtual space so why do we have to deal with it? But it's there. You know what I'm talking about. Dead sites. Websites, for whatever reason, are no longer being updated. And this pollution does have an impact on the real world.

Most of these sites are usually the results of someone who downloaded a free website builder and wanted to make a website. This person probably had a good theme for his website and thought how much fun it would be to keep it going. Creating and running a free website seems simple enough. What usually happens is that other things get in the way. Interests shift or boredom sets in or the owner finds that he or she no longer has the time to spend on it. So the site stays there, neglected and unchanged.

Why is this a problem?

For one thing the information for the website is stored in a server somewhere. That means electricity is spent in running that server which is holding information that is now obsolete and, because it is obsolete, no one is reading it.

It also increases search traffic. It lengthens the time to search for relevant topics because a searcher will be wasting time going through links that are now no longer relevant.

As information is stored but not deleted, people have to buy additional servers to meet with demand. That means an increase in actual space but, more damningly, increase in the demand for power. True servers don't take up that much space or use that much power but it all still adds up.

The thing is, the solution to this is simple. Delete your old websites. Host servers should have a clause that lets them delete materials that have not been updated after an amount of time has passed.

We should take care of our environment, even the virtual one.

Strategies for social media optimisation

Thu, 24 Jun 2010 00:20:38 -0400

Optimising for the social media can be a smart way to extend the reach of your search engine optimisation plan. Finding your way into a social media community can help your off-page optimisation and open your site to a new audience at the same time. Many businesses, however, have found social media a very difficult field to get into, and it takes a lot of hard work before and during your campaign.

When you decide to take on social media as part of your SEO, you do have a number of options. Obviously you have the option of which social media site to target and how to target it, but you can also choose to work from within your own pages, or go onto the social media site itself. Many sites choose to optimise for social media from within their own site, at least at first. You can discuss your options with us at SearchEngineOptimization.co.uk.

There are as many possible strategies for optimising your pages for social media as there are sites on the net. Here are a couple of the more central ideas:

*Making the site attractive for users of specific social media sites. This is a basic strategy used by a broad swathe of sites. Essentially, on-page social media optimisation should involve embedding social media features on your pages wherever you can. This might mean placing a short list of social media bookmarks above your content, or embedding a social media commentary box somewhere on your site.

*Designing content specifically with social media in mind. Once you’ve paved the way with the right kind of features on your pages, it’s important to make sure your content is of a type that fits in with the social group you’re targeting. Twitter users, for example, tend to appreciate informal blog-style content more than formal articles. Digg users tend to go for numbered lists. The style of your content must be carefully considered.

*Becoming a useful resource for social media users. Once you know your audience, you can try to enhance your relationship with them by providing them with the information they need. Becoming a resource is a way to get social media users to spread the word about your site.

*Becoming a social hub. One of the best ways to nurture repeat traffic for any audience is to open up the pathways of communication on a site. Social media users are used to being able to freely comment on material, and may get frustrated if there is no way to communicate on your site.

When considering social media as part of your search engine optimization campaign, the thing of utmost importance is selecting the right social media site or sites. As most site owners know through their own personal preferences, social media sites attract different groups of users. A bookmarking site like Digg might attract the more technically-minded, LinkedIn tends to attract professionals, and Twitter tends to attract highly socially active mobile media users. These different sites may or may not fit in with your business, so it’s important to do your research.

Conficker Virus Continues to Mutate

Mon, 08 Feb 2010 18:39:52 -0500

Never before has antivirus software been as important as it is today. The Conficker virus (or more correctly, Conficker worm) is posing a serious threat on computers and computer networks worldwide. Currently millions of computers are infected by this worm which is constantly mutating and posing serious threats to the integrity of the internet. Currently the sinister activities of this worm mostly concern spam email, which in itself is both an annoyance and a security threat, however experts fear that the worm might turn its activities to far more dangerous exploits in the future.

The story of how Conficker has gained such a stranglehold is rapidly becoming legendary. Despite a concerted and coordinated attack on the worm by computer and software specialists, Conficker has succeeded in penetrating successive layers of defence in order to take control of computers within the home and organisations such as government offices, universities and the military. Once a computer becomes infected, the worm turns it into what is termed a zombie computer under the control of the worm's creators.

Despite the fact that Conficker has been around since October 2008, it is still at large and is continuing to spread. The worm is able to mutate continually and receive instructions from its creators through peer to peer updates, and it is this ability that makes the worm so dangerous and elusive.

It is extremely important that everyone who uses a computer connected to the internet should check that their machine is not infected by the Conficker worm. To do this you need to install antivirus software onto your computer and make sure that the virus database installed with this software is completely up to date. Then you need to run a 100% scan of your files. If Conficker is present it will be detected and you will receive a warning along with instructions and options on removing it. You should follow these carefully and once you have removed the infection then you should enable your antivirus software to monitor your computer for threats of re-infection. As Conficker is often mutating and other viruses are released periodically, you should ensure that your antivirus software database is kept up to date on a daily basis using automatic updates.

Three Reasons to Move Your Web and Email Security to SaaS

Sun, 24 Jan 2010 19:38:54 -0500

Here are the top three benefits of moving your security to SaaS:

1: Better manageability.
In most organizations today, security revolves around building and managing either hardware and software or appliances. IT teams must spend a majority of their time focusing on licensing, updates, performance and availability for a host of security systems strewn about the enterprise. They also struggle with implementation and setup costs, as well as compatibility issues. This leaves little time for managing what's most important—the business processes that mitigate risk.

With SaaS, companies can eliminate the burden of managing infrastructure and focus on developing and enforcing streamlined policies. They can also direct responses to overall threats via a single console, rather than having to tweak configurations at distributed locations.

2: More proactive protection.
It would take a larger IT team than the majority of companies have to address the security challenges most organizations face. As an example, Forrester found that 711,912 new malware threats were reported in 2007, which translates into 1,950 new malware attacks each day. And the Web is becoming increasingly more dangerous, with many of the top search queries resulting in at least one malicious URL. To adequately combat most of these threats, IT teams need immediate and detailed knowledge of emerging attack vectors. One or two staff members devoted to security can't possibly detect and mitigate these risks quickly enough to ward off serious damage.

With SaaS, companies don't have to be security experts. Instead, they can depend on the expertise of a provider that is constantly monitoring and combating new threats to the network. Using signature, behavior and heuristic analysis in tandem with access and policy controls, a SaaS provider can quickly thwart spam, virus, spyware and phishing attacks within email as well as detect inappropriate content and malware, on Web sites that users visit. And since this protection is in the cloud, providers can eliminate the threat before it impacts the network.

3: Enhanced cost-savings.
One of the biggest issues for many organizations is determining if security SaaS adds to the bottom line. In a 2007 study, market research firm Gartner Inc. found that SaaS secure Web gateway solutions cost as much as $40 less per user than appliances. Companies realize these savings by having a subscription model with predictable costs. SaaS offers immediate savings by eliminating the need for infrastructure and the personnel to manage that infrastructure. Companies can see additional cost benefits from needing less storage and bandwidth since a lot of spam and other false content is handled off-network.

SaaS also saves money by saving resources. For instance, if a company builds its network to support 15 million inbound email messages per day and 14 million are purely junk, that's a lot of money wasted trying to deal with the volume on-premise. After moving to an in-the-cloud offering, you only need to support a million messages per day on your own network so bandwidth consumption is drastically reduced. By ridding the network of that extra burden, companies could also see a boost in performance.

Importance of IT Support in Business

Tue, 05 Jan 2010 17:40:29 -0500

Virtually every company depends on its computer network. Its cash flow and inventory are just two of the figures that need to be closely monitored and this can only be done with assurance through a functioning computer system. In addition, the clients are serviced through computer generated software and any interruption in the system will cost the Business clients. Clients will go to companies that respond quickly to their needs and will not be understanding when a company is offline for a considerable period of time.

IT Support is a necessary ingredient for a successful Business. As long as the company servicing your needs is excellent, it makes little difference in the method of service. Many companies have gone offshore seeking IT Support for their Businesses. It is not necessary for the technicians to be on site in order to service the IT network. This can be done remotely and works very well. The problem with the offshore approach is that there are justifiable complaints in understanding the offshore personnel. Though they may be fluent in the language of the company, accents are frustrating. Offshore is cheaper and the decision has to be made whether the frugality is worth the frustration. Onshore IT support is preferable with no language problems resulting.

In house computer teams are prevalent in larger corporations. This is an expensive way to gain IT Support, but if it is effective there is nothing wrong with this system. Whatever IT Support is used by Business; it must be ready to service the company on a 24/7 basis. The company can be called on site or remedy the problem remotely but the response time needs to be fast. The IT Support must be able to alleviate the negative situation as soon as possible. Make sure you have an IT Support company in place prior to a breakdown in computer services.

IT Support must be excellent. Without great support, the advanced technology of the company will be rendered useless, if it cannot be brought online immediately after a problem. IT Support in Business is the vital support system that all else depends upon.

The Evolving Challenge of Security

Fri, 01 Jan 2010 20:45:54 -0500

As more and more organizations turn to Web 2.0 technologies within their business, malware writers are targeting these applications as a method of distribution. An estimated 85% of all threats are emerging from the Web identifying it as the number one delivery system for malware. At least five percent of heavily trafficked "trusted" Web sites are now harboring malware. That makes web security for businesses increasingly complex, because web filtering systems and blocking alone are unable to protect a network if they cannot detect the attacks. For businesses to keep their data and employees safe, malware protection is key.

For some organizations, blocking access to social networks might be a realistic option, but it would not address other Web security issues like phishing and pharming attacks, drive-by downloads, and user access to proxy bypass sites. With greater sophistication employed by those inflicting the attacks, we are now seeing an unparalleled number of infected PCs and networks. Research shows that 6,000 Web pages are infected every day. Four out of five of them belong to hacked inoffensive Web sites.

Hidden Malware Threats
Malware writers distribute threats using a variety of means, including Web sites, instant messaging services and email. Cyber criminals have become innovative in their approach, inserting malware into the everyday online activities of the end-user. Malware writers often utilize highly visible news stories to create illegitimate sites that fool users. End-users unknowingly infect their computers by clicking on what is believed to be an innocuous Web site or pop-up.

Other examples of hidden threats include malware writers placing an overwhelming amount of information in their End User License Agreements (EULA). Knowing that most users will ignore the lengthy and ambiguous language of the EULA, developers are able to "obtain" permission to download their malware or spyware onto a client machine.

Threats are now so sophisticated they are often disguised as legitimate traffic entering through well-established ports, allowing them to bypass traditional security defenses like firewalls and other perimeter solutions. These threats can dodge web filtering systems. After installation, most applications disguise themselves as trusted programs to evade detection and removal.

Impact to Business
The Business community is impacted by the enormous cost of malware. Estimates reflect that some form of spyware or malware has infected more than two thirds of PCs. The average cost of each infected workstation to any business is £500 (based on IT services, downtime and re-imaging). Assuming a business has fifty users, 79% (39.5) who have a an infection, at £500 per workstation, a company can expect to spend over £20K to clean all infected machines - per incidence of infection. That number does not even take into account data loss and other potential ramifications.

Future Trends and Vulnerabilities
As cyber criminals employ even more advanced techniques to avoid detection, Web-based malware will become even more difficult to detect and remove. We can not only expect the number of Web 2.0 users to grow further, but we can predict that there will be adaptations, or new creations, of social networking tools also.
Information security professionals should be considering a dynamic, perimeter Web security service that provides web filtering for inappropriate sites (sexual content, violence, etc.); filters inbound pages for spyware and viruses; supports outbound data lead prevention by scanning content; and ensures that mobile laptop users are protected to truly detect and block new and advanced forms of malware.
