Proxy servers, or application gateways, provide their services by being an intermediate system for a network connection. A listening agent on the proxy server receives a request for a network action and, on behalf of the client, fulfills the request.

The connection comes from the proxy server to the destination and the data are passed back to the proxy. The final data transfer occurs between the gateway server and the client. At no time do the client and final destination make direct contact.

Some applications require modification to work with a proxy server. The SOCKS4 and SOCKS5 application gateways offer a library interface for an application developer to interoperate with the SOCKS gateway device with minimal difficulty. Other applications can be assisted through a helper application.

The biggest benefit for the detection and prevention of network-based attacks is the role application gateways play in a network architecture. Proxies act as application-level normalizers, fully reassembling the communications stream at the application layer in order to forward the data. This can be used to inspect traffic and optionally pass or deny the payload. Because the traffic is normalized, as it would need to be for the listening application, evasion techniques become significantly more difficult to effect. This includes fragmentation and network reordering, obfuscation through payload encoding, and the insertion of bogus data. The defense using proxy as one of network defense are consider as Ethical Relativism while proxy are commonly used as basic defense being used by every company not just for firewall protection but also to speed up the connection.

Application gateways can be either generic connection proxies or specific to an application protocol. An example of the latter is an FTP gateway, which integrates with the FTP application. The client modifies its requests to be interpreted by the proxy, which then passes them on to the server.

A generic application gateway may include a central electronic-mail hub. The ease of management afforded by a single network transit point, such as a mail hub, can also be used to screen mail content for malicious attachments or content. Messages that are detected as containing dangerous content can be discarded or altered to disable their malice.

This component has to be further subdivided into two portions: the platform on which the worm is executing and the platform of the target. This attack element can be a compiled binary or an interpreted script, which utilizes a network component from the attacking host, such as a client socket or a network aware application, to transfer itself to its victim.

A main factor of the attack component is the nature of the target being attacked, specifically its platform and operating system. Attack components that are limited to one platform or method rely on finding hosts vulnerable to only this particular exploit. For a worm to support multiple vectors of compromise or various target platforms of a similar type, it must be large.

This extra weight can slow down any one instance of a worm attack or, in a macroscopic view, more quickly clog the network. Other attacks include session hijacking and credential theft (such as passwords and cookies) attacks. Here the attack does not involve any escalation of privileges, but does assist the worm in gaining access to additional systems.

These attack elements are also most often used in intrusion detection signature generation. Since the attack is executed between two hosts and over the network, it is visible to monitoring systems. This provides the most accessible wide area monitoring of the network for the presence of an active worm. However, it requires a signature of the attack to trigger an alert. Furthermore, passive intrusion detection systems cannot stop the worm, and the administrator is alerted to the presence of the worm only as it gains another host.

The most important attack is online shop attack, when it happens, several things should be done such as migration opencart vs zencart, so it is important to keep your sites secure.

Lets have look below tips before you choose the best one:
1. Features Quality

Feature is the main thing you should look into buying hosting. Currently, there are so many hosting providers that seek to improve the quality of their features in order to face competition with other providers. If not, the customer confirmed immediately fled to other providers. Well, with this increasing feature, could bind and lock their client not to migrate somewhere else.

So what features should be considered?
Here are the main features you should check in web hosting provider:

- SPACE (Large hosting capacity, the bigger the better).
- Bandwidth (Large load data from either the upload or download, the bigger the better).
- Uptime (For websites not often down list, select the hosting uptime which is stable, at least 98% to the above)
- My SQL (more is better)
- Addon Domains (useful for those who want to have more than 1 domain on 1 hosting account)

2. Price Comparison

Once you see its features, if you do not care about the price issue it does not really matter. Another case if you are really considering this issue, then the best solution other than seeing the features offered is by comparing prices from one provider to another provider. This way you can draw conclusions Which web hosting company you use decent.

But remember! Do not be fooled by cheap price with good features then you take for granted. Conversely, it does not mean it is with the price of cheap web hosting cheap and not necessarily be good, there are other considerations that you should look. Do not forget also a price that is usually temporary. Usually some web hosting provides cheap prices only in the first year alone. Medium time extension prices soaring, you’ll want to ask this problem.

3. Number of Clients

Number of clients is a reflection of a hosting judged good or bad by his client. More and more clients, the hosting company usually reliable quality. For that, it would not hurt you also ask this problem to the relevant customer service.

4. Match Requirement

Do not be fooled by hosting also provides versatile features unlimited and that provider has been trusted by clients.
Which means what?

Purchase (rent) hosting your online business needs. Because it would be useless if you require only 50 MB of which only worth several dollar rather than buying others cause you’re tempted unlimited features that you won’t used with higher price. Certainly a far cry from the price comparison, and a lot of unused space will be wasted. Unless you intend to make a lot of websites at once or for long-term business, which does require a large space.

5. Server Location

If you target your marketing in certain countries. We recommend that you have to adjust with the provider you use. Because this will affect the speed of access to your target in question. If they are too long to wait for your web loading, it is not impossible they just run away. Usually the USA servers are lighter and can be easily accessed around the world.

6. Support

The characteristics of web hosting that is professionally managed support is responsive, patient, and always online 24 hours a day 7 days a week. Especially if you’re new to dealing with hosting issues, usually a lot of obstacles you will encounter. This is where the function of the responsive support it means a lot. You will be assisted until your site has really online. They usually also provide a complete range of communication media such as IM, email, phone, or directly come to the place.

7. Complete Address

As mentioned earlier, a good web hosting provider usually also indicate the completeness of the address. Although the client does not have to come into place, but at least will make the client feel safe with that address, so they need not fear that provider only fictitious or afraid to be left vague at times.

8. Company Age

The more older the age of the web hosting provider, usually the more experienced they are dealing with hosting issues.
Old age also showed the higher their flying hours to handle the hosting. They maintain strict program, the software until the contents are allowed to use. Because there is rarely a hosting provider out of business due to not be able to manage their hosting.

Last but not least, everyone would dream on fast hosting with age, then try out fasthosts. Great price and offer other features such as free scripts, site builder, and many more, it is mention on ipage host review.

Cross selling involves five fundamentals:
• You have to know your products very well.
• You have to know your clients. To get the best results identify which customers are your best target.
• Ask questions and listen for clues.
• Pay attention to clients needs and only suggest relevant products.
• Suggest, don’t impose. These way clients will feel comfortable and more likely to accept your offer.

Most of the time, cross selling is a natural process, involving a simple operation: telling customers about your products. In software marketing, the publisher needs to establish which software product can be correlated with another one and be sold together as a package deal. Both the selection and the price can be based on several customer and product criteria, which should be set up before deciding on using the cross selling technique. These bundles may be added to the online shopping cart or advertised as a special software promotion on the site.

Successful cross selling can be achieved by applying several rules:
• Right timing. Don’t push sales if it seems the client doesn’t have the financial resources at that moment. Try to find out what the clients budget is and make your offer accordingly.
• Relevance. Suggesting too many software products unrelated to the original one may overwhelm the client and lead to failure.
• Post recommendations on the site. Professionals, experts or other customers may post their opinion and their recommendations on the site. It can show up as a list of related items bought by other customers that purchased the same product.
• Place cross selling items throughout your site, where they can help shoppers learn about your software products and business. Try mixing and matching different items to see which combinations work best.
• Offer a range of prices: low cost items may be considered impulse buys, but the clients may also purchase higher priced items that fit their needs.
The most important aspect in cross selling is customer satisfaction with the first software product they purchase, alongside with price and how well additional products fit their needs. In order for cross selling to work, the focus should be on the customer, not on pushing a certain software program. Before talking about additional products or services, the customer’s problems must be solved. Also, the customer needs to know how useful is the product you’re trying to sell in the first place.

What’s the most important downside of cross selling? Annoying clients to the point they leave without buying anything. This occurs if you continue to sell after the customer says he’s not interesting or when you’re pushing a product that’s not useful to the customer. In the end, combining customer service and cross selling will lead to increased online software sales.

Selling software online is not an easy task. How do you make the client truly understand your product and trust it and your company enough to pay the price? Like it or not, it’s very similar to selling face to face: the first impression may be decisive for the client’s future actions. Online, the website is your face.

It has to be comprehensible and easy to use. Here are a few tips on how your website should be to sell software better:
• It has to look professional and attractive at the same time

You don’t have to show off your web designer skills. Too many colours, graphics, flash animations or drop-down boxes can only tire the visitors and make them leave faster. Fewer graphic will also make the site load faster. At the same time, it shouldn’t be dull, so it needs to be somewhere in the middle.
• Make sure your message comes across loud and clear.
In order to sell more software, information about software products must be easy to find, easy to follow and the same goes for the order process. Since most information is in the text, make it easy to read. Some coloured backgrounds make the text difficult to read, like purples, orange and reds. On the other hand, dark backgrounds may have a depressing effect on the visitor’s mood. The text colour is very important. Keep in mind that different browsers show colours differently, so don’t go crazy with it. It’s better to use Plain fonts, like Arial, Times New Roman, Verdana and Courier, because they’re easier to read. Fancier fonts may be used for headlines, but not full text. Remember though that sans serif fonts are easier to read on screen.
• Easy navigation is law.
Make sure there’s a link to the homepage at the top left of every page, except the homepage itself. Be careful not to have dead end from which the visitor can’t find their way back to where they came from. Place the most important links in the top part of each page. Clearly mark read and unread links, preferably using standard colours.
• Base the site’s hierarchy on your customers needs.
Don’t make them search the entire site before they find information about products, prices and payment methods.
• Don’t make pages too long.
A web shouldn’t be more than 23 normal pages lengths, as no one likes an endless scrolling. If you have information for more than that, divide it into several pages with short information clips on the main index page leading to the second page.
• Check all the links on your website to make sure they lead to a page.
Tags from the navigation menu must be representative for what that page is about.
• Serve friendly error messages.
Don’t let the visitors see a page with 404 not found written on it. Put your creativity to good use. Error messages may include navigation to documents that do exist, a search box or a contact email address.
• Have a privacy statement and testimonials.
Potential clients must feel confident dealing with you. Having a separate page to express your policy towards their email addresses, how you accept orders and gather information, who has access to information and how you use that information will help you sell more software. Also make a separate page for comments from satisfied customers. Offer to include links to the customers websites in return for using their comments.
• Contact information or a link to it should be on every page.
If customers need additional information about the product, contact information like a phone number and an email address should be easy to find on the website. Let people know the hours and days of operation and the time needed to answer their requests. Give a contact name; it makes people have more faith that someone will actually read their message.
• Set up a frequently-asked-questions (FAQ) page.
Base it on real questions your customers had in the past.

Install security patches. Vulnerabilities in software are constantly being discovered and they don’t discriminate by vendor or platform. It’s not simply a matter of updating Windows; at least monthly, check for and apply updates for all software you use.

Use a firewall. No Internet connection is safe without one. Firewalls are necessary even if you have a dial-up Internet connection – it takes only minutes for a a non-firewalled computer to be infected.

Secure your browser. Many labor under the dangerous misconception that only Internet Explorer is a problem. It’s not the browser you need to be concerned about. Nor is it a matter of simply avoiding certain ‘types’ of sites. Known, legitimate websites are frequently being compromised and implanted with malicious javascript that foists malware onto visitors’ computers. To ensure optimum browsing safety, the best tip is to disable javascript for all but the most essential of sites – such as your banking or regular ecommerce sites. Not only will you enjoy safer browsing, you’ll be able to eliminate unwanted pop-ups as well.

Take control of your email. Avoid opening email attachments received unexpectedly – no matter who appears to have sent it. Remember that most worms and trojan-laden spam try to spoof the sender’s name. And make sure your email client isn’t leaving you open to infection. Reading email in plain text offers important security benefits that more than offset the loss of pretty colored fonts.

Treat IM suspiciously. Instant Messaging is a frequent target of worms and trojans. Treat it just as you would email.

Avoid P2P and distributed filesharing. Torrent, Kazaa, Gnutella, Morpheus and at least a dozen other filesharing networks exist. Most are free. And all are rife with trojans, viruses, worms, adware, spyware, and every other form of malicious code imaginable. There’s no such thing as safe anonymous filesharing. Avoid it like the plague.

Keep abreast of Internet scams. Criminals think of clever ways to separate you from your hard earned cash. Don’t get fooled by emails telling sad stories, or making unsolicited job offers, or promising lotto winnings. Likewise, beware of email masquerading as a security concern from your bank or other eCommerce site.

Don’t fall victim to virus hoaxes. Dire sounding email spreading FUD about non-existent threats serve only to spread needless alarm and may even cause you to delete perfectly legitimate files in response.

Remember, there’s far more good than bad on the Internet. The goal isn’t to be paranoid. The goal is to be cautious, aware, and even suspicious. By following the tips above and becoming actively engaged in your own security, you’ll not only be protecting yourself, you’ll be contributing to the protection and betterment of the Internet as a whole.

This may come as a surprise to some, but we make very little money selling software licenses. The vast majority of our revenue comes through consulting services writing code for hire. Having now done this for several years, we’ve learned some hard lessons. On a few projects the lessons were so hard we actually lost money.

A few months ago I put together somewhat of a manifesto-type document intended to address the difficulties we’ve faced in developing software for clients. I’m pleased to say that it’s made a noticeable difference so far for us. My hope is that this blog entry will be read by others who develop software on a consulting basis, so that they can learn these lessons the easy way rather than the way we learned them.

What follows in this article is a summary of one of the main principles we now follow in developing software the 15% rule. If you’d like, you’re welcome to read the full Our Approach to Software Development document.

For the impatient, the 15% rule goes like this
Before undertaking a development project we create a statement of work (which acts as a contract and a specification) that outlines what we’ll do, how many hours it will require, and how much it will cost the client. As part of the contract we commit to invest up to the amount of time outlined in the document plus 15%. That is, if the statement of work says that the project will take us 100 hours to complete, we’ll spend up to 115 hours (but no more). As to where-fores and why-tos on how this works, read on.

Those that have developed software for hire know that the end product almost never ends up exactly as the client had pictured. There are invariably tweaks that will need to be made (that may or may not have been discussed up front) in order to get the thing to at least resemble what the client has in mind. And, yes, this can happen even if you spend hours upon hour’s fine tuning the specification to reflect the client’s wishes. Additionally, technical issues can crop up that weren’t anticipated by the programming team. In theory, the better the programming team the less likely this should be, but it doesn’t always end up that way (Microsoft’s Vista operating system is a sterling example). These two factors, among others, equate to the risk that is inherent in the project. Something isn’t going to go right, and that will almost always mean someone pays or loses more money than originally anticipated. The question is who should be responsible to account for those extra dollars?

Up until relatively recently, we would shoulder almost all of the risk in our projects. If the app didn’t do what the client had in mind, or if unforeseen technical issues cropped up, it generally came out of our pockets. For the most part it wasn’t a huge problem, but always seemed to have at least some effect (the extreme cases obviously being when we lost money on a project).

This seems kind of unfair, doesn’t it? The risk inherent to the project isn’t necessarily the fault of either party. It’s just there. We didn’t put it there, and neither did the client. As such, it shouldn’t be the case that one party shoulders it all. That’s where the 15% rule comes in.

The 15% rule allows both parties to share the risk. By following this rule, we’re acknowledging that something probably won’t go as either party intended, so we need a buffer to handle the stuff that spills over. By capping it at a specific amount, though, we’re also ensuring that the buffer isn’t so big that it devours the profits of the developers.

For the most part, the clients with whom we’ve used the 15% rule are just fine with it. It is a pretty reasonable arrangement, after all. We have had the occasional party that squirms and wiggles about it, but, in the end, they’ve gone along with it and I think everyone has benefited as a result.
