IP Address and Online Security

Although the Internet has given us a world of benefits, not many know the basics of how all them are even possible. Computers linked to this supernetwork are actually able to communicate with each other with the use of their IP addresses which serve as their unique identifiers. When you’re online, you are able to send a request to the server of the website you visit using this address. A reply is then sent to you through your IP which serves as your location on the Internet.

Of course, having that IP is good because it allows you to link up with other computers. But it’s not necessary that you surf with it exposed. You may start to wonder why there seems to be a problem showing your identity to the rest of the online world. Actually, the reasons are simple. Some people just might abuse you through that IP. When you run around the web exposed, hackers could easily locate you, install malware and keyloggers on your system and thereby compromise your safety.

There are many possible scenarios that can happen when you don’t protect your identity online but the most common ones involve online purchases. When buy something through a website, you will have to enter your credit card information. The question is, how safe is that website? Hackers are practically everywhere around the Internet and if you’re entering your sensitive information through an unsecured site, that could mean disaster for you. You could even end up with your identity being thieved.

Another major threat you may face when you surf the web exposed is malware which is an umbrella terms for all types of online contaminants such as viruses, worms, trojans and the like. When your IP address is out in the open, any crazed geek could easily reach you and install all sorts of these malware into your system. You know what that means. When those nasty codes are already in place, they can start working and you could lose everything you’ve got in that computer in seconds. This is definitely possible. In fact, a lot of Internet users have reported being victimized in this manner and this is just another reason why Internet security should always be taken seriously.

Besides, when you go online, that’s your own personal affair and whichever site you visit is your own responsibility. Nobody needs to be snooped on and if you do value your privacy, you won’t ever allow anybody to look into what you’re doing. It doesn’t mean that you’re necessarily entering sleazy sites. Even if you’re just doing your research or emailing friends, everything should still be your own business and nobody else’s. When you surf with your IP address exposed, companies out there could look into what you do in order to obtain a profile that they can use it for advertising purposes. When they assess that you are probably going to patronize their products or services, they will bombard you with promotional emails which may be harmless but are still annoying, anyway.

In any case, when you go online, that’s your business and nobody else’s and it’s also your right to keep your computer safe so, by all means, make it with an IP hiding software.

When you hide your IP address, you hide your identity and your location. That way, nobody you can surf anonymously and safely.

Blogging Security Warnings

Blogs are vulnerable and need security, developers work overtime on this, releasing updates as fast as they can in response to a threat. Still, you need to keep up with the news on security issues and risks. You must read tips on keeping your blog safe from new hackers attacking blog passwords.

Sometimes Internet Explorer
and some other applications, add a bit to the file to mark it as being downloaded from the Internet. It serves as a warning that this may be unsafe content. If the file is digitally signed, the warning does not have the red shield, and the publisher is listed in the dialog, but otherwise it stays the same.

Internet Explorer adds a flag to downloaded file through alternate data streams, and there are tools that can show you those streams, and even the built-in unzip tool in Windows adds the same flag if the archive that was unzipped has the flag set. The point, however, was not how a very technically savvy user can download an advanced tool and manually review the alternate data streams, and possibly remove them. If all you want to do is remove that flag it would be far simpler, in fact, to uncheck the box in the dialog for “Always ask before opening this file”; although maybe inspecting and twiddling with alternate data streams would be more satisfying for some segment of computer users.

You must educate yourself first and then educate your users. Teach them that the warning is there so that they can assess whether they want to accept the risk involved in opening applications off the Internet. In this case, you have digitally signed the application so they can trace it to you and have assurance that they are, in fact, opening a trusted application. Anytime they get a dialog like this they should evaluate it and see if they really want to accept that risk or not. If the publisher is unknown, they have no way to tell who wrote the application, and should consider it a higher risk.

There are very good reasons for these warnings in many cases. Rather than trying to prevent users from seeing them we all need to do our part to help users understand what they are seeing and make appropriate decisions based on that data. That would provide a savvier user base and a more secure Eco-system in the long run. We cannot keep focusing on preventing people from making risk management decisions any longer. If we do, eventually, they will realize they do not have the skills to do so, and that nobody is willing to help them acquire those skills. At that point, the Eco-system will be in danger of collapse.

Social networking blogs like give scam artists and virus writers new ways to package tried-but-true tricks. The latest example of this making the rounds is an e-mail that appears to be an invitation from Face book to add a friend: A recipient who opens an attached image to take a look at their new friend instead opens the door for hackers to compromise his PC.

Here a few tips and things to keep in mind that can help you avoid being burned by e-mail based attacks.

E-mail addresses in the “From” field can be easily spoofed. So never open attachments in e-mails that you weren’t expecting, even if the -mail appears to come from some person you know and trust. (Legitimate friend requests, in fact, don’t include attachments).

Avoid responding to unsolicited e-mails. You’ll only let spammers know they’ve got a mark for future e-mails.

Consider switching from HTML e-mail to text-based messages only. Malicious JavaScript and nasty instructions written in other powerful scripting languages can be embedded in HTML messages, and in many cases that code will load as soon as you view the message.
