• Game Players 31.07.2021 Comments Off on Protecting Networks Is Just a Game

    ScienceDaily (July 28, 2011) – How can an organization detect the onset of an attack on its computer network giving it time to respond quickly and block any intrusion or compromise of its data? Modern firewalls and other technology are already in place, but these have not prevented major attacks on prominent networks in recent months. Now, information technologist Heechang Shin of Iona College in New Rochelle, NY, has used game theory to develop a defense mechanism for networks that is more effective than previous approaches. Writing in the International Journal of Business Continuity and Risk Management, Shin explains that with the tremendous growth in numbers of computing and other devices connected to networks, information systems security has become an issue of serious global concern. He points out that each incident might not only cause significant disruption to services affecting many thousands of people but for a commercial operation can take as much as 1 percent of annual sales, per incident. That number amounts to tens of millions of dollars for the average publicly listed company, Shin says.

    Shin has now developed an effective anti-hacking tool based on a game theoretic model, called defensive forecasting, which can detect network intrusions in real time. The tool, by playing a “game” of reality versus forecast, wins when reality matches its forecast and it sends out an alert to block the intrusion.

    Importantly, the tool works on real-time data flowing in and out of the network rather than analyzing logs, an approach that can only detect network intrusions after they have taken place. The game theoretic model continuously trains the tool so that it can recognize the patterns of typical network attacks: denial of service attacks, such as a syn flood, unauthorized access from remote machines in which login passwords are being guessed or brute-force tested, attacks by insiders with “superuser” or system root privileges or probing attacks in which software carries out surveillance or port scanning to find a way into the system.

    In order to measure the effectiveness of the tool, Shin compared the approach using the semi-synthetic dataset generated from raw TCP/IP dump data by simulating a typical US Air Force LAN to a network intrusion system based on a support vector machine (SVM), which is considered one of the best classification methods for network intrusion detection. Experimental results show that the tool is as good as or better than the one based on SVM for detecting network intrusion while the tool adds the benefit of real-time detection.

  • Internet & Site 31.07.2021 Comments Off on Microsoft Cautions Users on Critical vulnerability in Internet Explorer

    Web based attacks are one of the most common forms of attack initiated by the criminals. Attackers exploit vulnerabilities on websites, web browsers and other web applications. Recently, Microsoft has alerted users on a critical vulnerability in Internet Explorer that could allow an attacker to execute malicious scripts. Attackers may exploit the vulnerability and compromise information security. The vulnerability is associated with the handling of Multipurpose Internet Mail Extensions (MIME) formatted requests by MIME HTML (MHTML). The vulnerability may in some instances cause an Internet user to execute a malicious script on visiting a malicious web page. MIME is a data format, which condenses binary structures as a text only format. MHTML allows applications to deliver MIME structures. The format requests from MIME may be manipulated by an attacker to inject malicious code in the victim’s computer. The vulnerability is similar to cross-site scripting attacks. However, in the malicious script may be executed in the client side context.

    An attacker may place an HTML link with malicious code on a website and tempt users to click on the link. When users accessing the site through Internet Explorer click on the link, the malicious code gets executed in their system. Usually, software developers find vulnerabilities through ethical hacking. In this case, Microsoft found that a proof-of-concept code for exploiting the vulnerability is available in the wild.

    Once executed, the malicious script may spoof the content, reveal information and perform arbitrary actions on the website on behalf of the targeted user without latter’s input. The extracted information may be misused by the attackers. The vulnerability affects all versions of Windows. Information security professionals at Microsoft are working with other partners to provide protection from the vulnerability. Meanwhile, Microsoft has provided a fixit solution. The fix it wizard has two options. The enable option locks down MHTML and the disable option unlocks the MHTML.

    Disabling ActiveX controls and Active scripting in Internet Explorer may also provide some protection to users. Microsoft may consider issuing a patch for the zero day vulnerability during one of its upcoming security updates.

  • Server & Programming 27.07.2021 Comments Off on What Is A Name Server

    The computer cannot understand English or any other common language. The internet is a network of such computers that do not understand the language that the common man understands. This means that a domain name typed in like www.yourdomain.com will not mean anything to the computer. This domain name that you type in needs to be translated into a string of numbers for the computer to understand it. This string of numbers is called IP Address. It looks like this: 202.157.34.10.

    It is not easy to remember a string of numbers like a domain name. Hence, we use domain names that we can understand and those domain names have corresponding IP Addresses that the computer can understand. But if this has to work, then every domain name should be translated into an IP Address that the computer understands. This translation is done by Name Servers. A name server is familiar with a domain name and their corresponding IP Addresses. Name Servers are also called Domain Name System Servers or DNS Servers.

    All the information from all the name servers around the world is stored in a central registry. It takes between 8 and 48 hours for all the information to be updated in the central registry when a new domain name is registered. Name Servers from around the world can access this registry and when the domain name is requested, they can get the corresponding IP Address from this registry.

    A domain name, when registered, needs at least two name servers. These are usually ns1.nameservername.com and ns2.nameservername.com. Here, “nameservername” is the name of the server. The first one is the primary name server and the second one is the secondary name server. The secondary name server acts as a backup that comes into effect only when the first name server is not responding.

    Certain steps need to be followed while registering a domain name. These may differ a little depending on the registrar, but most of the steps are the same.

    If you need to register a .com domain name, the steps are given below :
    1. You get an account with the domain name registrar when you register a domain name. Log into your account with the registrar.
    2. You will see an option to manage your domain name within your account console.
    3. Select the domain name for which you want a name server. This will open a page for managing the domain.
    4. Select “add name servers” on this page under the name server details section.
    5. Enter the name and IP Address of the new name server and click on “Add”.
    6. You should get a confirmation message indication that you have added a new name server once you are done with registering it.
    7. Normally, you can start using the new name server immediately.

  • Server & Programming 26.07.2021 Comments Off on Setting Up A Web Conference Server

    People who meet online regularly rarely think about the web conference server. While this is an important component of successful web conference meetings, once it works they dont need to. From the outset it establishes control of the presentation and allows the moderator to change the presenter when required. Those who set up meetings online should have an understanding of the web conference server. They need to know about its basic components and their importance to a well structured web conference.

    The Functions of the Web Conference Server

    Even a company new to web conferencing can quickly understand the basic features and start hosting meetings. Naturally, the components are not limited to the hosting of meetings. Web conferencing also allow a company to streamline its operations and save money. Web conference servers have a variety of functions including:

    Application sharing: This is one of the best features of web conference solutions. Users can collaborate using the same application.
    Managing media files: This is important given the wide range of file types that may be used in any one presentation. This includes still images such as JPEGs and TIFFs, and audio files.
    Collaboration: This is the backbone of any web conference utility. It covers a wide range of features such as chat, file transfer and whiteboard.

    The Web Conference Server Infrastructure

    The ability to host a web conference depends on basic elements such as phone lines and Internet service. Depending on the size of the network and teams involved additional components may be needed. An Internet Locator Service (ILS) has proven to be valuable to some users in setting up a web conference server. The ILS performs two main functions:

    It allows the host to maintain an up-to-date directory of anyone who may need to be involved in a web conference at any time. This makes it easy to keep track of participants and to notify them of meetings or send out reminders.
    It will address bandwidth concerns ensuring that the web conference is not hampered by low speed transmission of data.

    To make the process easier, some users opt for meeting software such as those offered by RHUB Communications. Typically these devices support both Mac and PC platforms and offer universal attendance technology. Their main advantage is that with direct ownership no monthly fees are required.

  • Computer & Multimedia 22.07.2021 Comments Off on The Advancement Of Pc Laptop Computers

    While technology in general has changed over the last 10 years, making life easier and more convenient, PC laptop computers have by far made the most change. In addition to the computer itself evolving, everything about the computer has been enhanced. This means computers today are smaller, faster, and they cost far less than a decade ago.

    If you use a computer while on business, at college, or you like to take a computer with you while taking a vacation, the options today are amazing. Most people will choose the standard type of laptop but the notebook is another great option, which again, is much smaller and even lighter in weight. However, the notebook offers better portability than a standard laptop.

    Looking at PC laptop computers now being sold, you cannot help but be in awe. For one thing, computers are lighter and while not all have had much change, the amount of power now offered and the incredible speed when on the internet is without doubt astonishing.

    Even though people all look for something different, having a computer with a web cam, built-in keyboard and mouse, battery that lasts longer, DVD/CD burning drive, and wireless technology means you get everything needed and more.

    Of course, you could stick with a desktop computer, which still works great, but the mobility and built-in features associated with PC laptop computers make them the favorite choice. This means you can take the computer wherever you go and have internet connection, allowing you to email, handle business meetings, or simply play online games.

    This means you could connect to the internet while waiting for your next flight, while in your hotel room while traveling on business, or sit out by the pool with a friend and just play games or answer emails. To enjoy internet connectivity but without running down the battery, all you need is a standard electrical outlet.

    PC laptop computers have even changed in size. Today, the smaller options are about 10×8 inches that comes with a 13-inch monitor but if you like a more normal size, then you could go with a 15×11-inch computer with a 17-inch monitor. Along with the actual computer being smaller, these laptops are also thinner.

    The smaller computers now have a thickness of just 0.7 inches whereas the larger ones are about 1.5 inches, which is still thinner than earlier models.
