Computer and Internet Security – Why the Security of Your Computer is Vital

Have you ever quizzed yourself as to the reason why you have suddenly realized that it is essential that you have a proper computer security system in place? The reason is that simple. Your computer stores all of your important information, tools, databases, intellectual property and transactions. Therefore, it is vital that you learn as much as possible about computer and internet security as it is important that this information should not be breached.

Now, let us take two persons for instance, Person A and Person B. Person A has a computer which is connected to the internet. This computer is therefore vulnerable to hacking because it has the capability of storing personal information like credit card numbers, bank account details, etc. on it. Now, for Person B, his computer is connected to the internet but he does not have a firewall installed. Therefore, he is also vulnerable to hacking and other damages caused by computer viruses and spy wares. Hence, it is clear that Person A is more susceptible to hacking and therefore he needs to have a better computer security system than, for example, Person B who has no computer and so is not connected to the internet.

What you need is a firewall installed on your computer. (Just in case if you do not have one already, go down to where you can download some good firewall software and win your self a high reputation among yourself). When you have installed a firewall, you need to be sure that it is properly configured. This can be done by talking to any computer experts or simply by doing some quick research about how to configure the firewall.

The role of the firewall is to monitor or filter traffic between the internet and your PC by using a series of rules. So, when you connect your computer to the internet, you run the risk of some unsolicited websites and stuff entering your PC unwantedly.

URL filtering is one way to fight this problem. It is a blocking function that allows you to block certain websites based on their URL. For example, you may be trying to view a certain website and an banner may pop-up so you can’t do so. If you want to view the site, you can choose another URL. Thus, both you and your computer is secured from a dangerous and unsolicited hacker.

To be able to achieve a good internet security, you need to follow some simple steps. These steps would not be so difficult if you have a simple program installed for the purpose. Basically, the program is in two functions; one, an entry point (which is your computer on the internet) and second, the filter/decider.

Proxy is used to filter internet traffic and this is a basic function of any good program. What is more, it is necessary to install a proxy program because the purpose of the second function is to monitor internet traffic to a limited extent and only after a certain amount of time, the website will be banned. You can’t be allowed to view a certain website; therefore, you’ll need a third party program to install a proxy website.

For alternative reasons, you can also try using “anonymous proxy servers”. These servers don’t proclaim to be anonymous and they may be bothering you with their presence. Sometimes, they cause hinderances to your PC as they are websites run by hackers and they want to monitor your online activities. If you use this server, make sure you download its source code and try running it.

Because, this software is free, you can try it and you’ll find that not only is it good for you but that it’s also free of charge. If you’re really considering it, make sure you can run it from your computer as the sources are not trustworthy.

Hacking – A Fullstop On E-system

Passion or Madness: Now days, it has become a passion to learn how to hack. Some of us do it for the sheer challenge, some for the sheer love for learning and new technologies. Regardless of what the reason is, with every hack someone is trying to improve the technology we rely on.

There are many hacking related skills one can learn, depending on the person and the type of hacking they want to do. As there are many opportunities and facets to the hacking world, it makes it complex to learn all things related to it.

But, it is never too late if you have the right information and the right techniques. In order to make sure that you have all the information you need, you can always study and learn hacking. The best part of it all is that, for all you know, you can be the next hacker that redefines the way we think about security.

Mentoring: There are many opportunities available for collaboration and snooping on hackers. If you have an interest in snooping on hackers or have the opportunity to learn from them, consider taking a class or participating in a workshops. You might be surprised how much knowledge they have about the technologies they use… and you can use what you’ve learned and put it to good use.

Sniffer: We have tools now that can let us track IP addresses. We can also tell how far away the IP address is from us, and we can sniff for firewalls, viruses, and other threats. We can also reveal a lot of other information about the person/company that we are dealing with.

Cache: We refer to the temporary files that store all the information that has been fetched over the net. Actually, the term ‘cache’ is a bit misleading. The information is not stored in order and there is no order to it. The information is usually stored in memory and while it is loading it is also stored in a temporary location so that it is not immediately discarded. The temporary location is emptied when the request for the information is finished and then the information is discarded.

Many hacking tools use a variety of modes of communication Protocols (Speakers, Morse code, Direct Sensing, etc.)

Protocols

•http which is a general term used for HTTP/ActiveX and often used by many InternetBrowsers, presents significant security risks. It is a specification supported by the Internet Engineering Task Force (IETF) and is responsible for the functioning of the World Wide Web. The primary concern of the IETF is the transfer of files and processes over the Internet.

The subsequent technologies, which are often but not always classified, follow between HTTP and TCP/IP and SPI.

Internet Protocol (IP)

•IP over SSL

• Internet Protocol (IP) is a set of protocols that offers Internet users the ability to communicate online using the TCP network. The IP protocol applies resource sharing and addressing methods among the computers on a network and is responsible for the flow of information exchanged during online transactions. Online users consists of computers that have been granted access by an Internet service provider (ISP).

Online Systems Management (OSMP)

•http://www.cert.org/vul_notes/VN219|

o Virus Bulletin No. 9110 provides updates on viruses that are specific to the Microsoft IIS 5.0 Extended Validation SSL Certificate. This Microsoft SSL certificate enables you to secure private data that pass through, including documents, e-mail messages, and on to databases, which store user credentials and other private information. This certificate also enables your site to display a secured page now and later, when your users click a protected link.

The CSR data must be verified and properly transformed in the digital object before it can be authenticated and then encrypted. Therefore, to access the signed certificate, the user must have the Bit-Authentication turned on for the Microsoft Exchange 2007 Online Explorer (E), which comes with the SSL functionality.

Effects of Certificate Fraud

A fraudulent Certificate could cause several problems for the user. The certificate could be fraudulent in the sense that the name of the sender or any essential part of the signature block is misrepresented or false. Physical inspection of the AIA may also be performed by an authorized third party, such as an auditor, in order to confirm the fact that the web site is legitimate. If SSL authentication is possible and has been enabled on the site, the browser will display a padlock and indicate that an SSL certificate is secured.

Reasons to Prevent Certificate Fraud

The instances of certificate fraud may be reduced if users and businesses implement evolving strategies and are informed about how the security process & monitoring mechanisms work.

How To Avoid Spyware Before It’s Too Late!

Unfortunately, most people don’t pay much attention to the threat posed by spyware until their level of infection has become acute and their private information has been compromised. The final result is that they become subject to an identity theft attempt. New methods of attack are being developed all the time and you need to get up to speed on the subject and stay informed of changes as they occur in order to know how to protect yourself.

First of all, if you are a careless surfer you are living dangerously and eventually you will get nailed. The smart thing is to set your computer environment up with a secure defensive perimeter and to prevent unauthorized access to your computer and check out any personal information that you have stored on your hard disk. If you surf the web, open attachments or use peer to peer applications then you risk being victimized.

The statistics are staggering and reveal just some of the tremendous amount of personal information that is present across the internet. According to requirements imposed by the federal government, we can all be traced back to our IP address. With that information in the wrong hands, a lot of people have a lot of problems.

The only solution is to minimize your risk of exposure. This requires you to be careful about the type of information that you divulge while online. Don’t assume that you can just offload your personal information to sites that are willing to accept financial information. Sites that are willing to acquire your information will have an address that you can contact them to confirm their legitimacy.

Other risk factors include file sharing programs, so you should download and install programs like the well-known P2P file sharing programs like BeXTRA or CoolWebSearch that help you keep your computer free from harmful viruses, hackers and worms. Surfing anonymously will also help keep your privacy since no one will be able to trace you and your actions.

Why should you risk it?

Secure surfing is one of the best ways to protect your identity and personal information. It’s not hard to understand why most people begin to take a liking to the idea and begin to make regular trips to the local library to surf the internet and download files. The truth is that they should avoid these activities because it is possible that they are the victims of online thieves.

The trailblazing technology of today has helped to make the whole process much safer and understanding students to use the internet and avoid harmful viruses. However, these efforts have not been able to totally rid the internet of its infamous reputation as a source of crimes and victim of fraud. Users that have criminal intent will never be able to track you using your IP address because mobile malware and other malicious programs will also be unable to track you.

Using this technology will also help you to stay protected since you will be able to encrypt your data which will render it totally unrecoverable once it is deleted from your computer. There are numerous applications available when it comes to protecting yourself from cyber crimes; one of which that is available is the IP hiding software. This software enables you to surf the web undetected through the IP address of origin. After the IP address is hidden, the site you visit will pretend to be from the computer you are using.

This is because the site is actually acting as a proxy server; one that originates from the computer you are using. If you are currently using a site that you are not sure of, then visit a local library or search online for a few reviews about the product.
