Oracles Java -- The undying list of vulnerabilities and exploits.

Many people think that Microsoft is still the source of vulnerabilities to viruses and exploits on their computers. This is no longer the case as improvements to Microsofts security model and Windows Update have significantly lowered the threat level of Microsoft products over the last few years. While you are still very vulnerable if using very old products that are no longer updated, like Windows 2000 or Windows NT4, new Windows versions like Windows 7, Vista, 2008 (and to a lesser extent XP) are far more secure than all of their previous operating systems. They are beginning to shake their reputation for insecure software.

The number one threat to any PC right now lies in Java. There are huge lists of vulnerabilities and exploits released by security analysts on a near weekly basis. These items sometimes go unpatched and exploited for months before a patch is released, and non-savvy users may not even keep their Java up to date, exposing them to more vulerabilities, longer.

Calculating the Strength of an AES-256 Cipher 

The Advanced Encryption Standard is the de-facto method for securing your data on the internet today. Encryption is a method of "encoding" your data, using a special code called a key, and a complex mathematical operation, to make your data unreadable to anyone without said key. Cracking AES encryption requires you to be able to "guess" the key. Now, guessing a simple key would be easy. A key using a single bit would be a single binary digit. Which is a "1" or a "0". However, the difficulty grows as the length of the key grows. A 5-bit key would have 32 possibilities. This is because for each bit you add, you are doubling the complexity of the key.

The 5-bit key could have the following possible values:

00000    00001    00011    00111    01111    11111

00010    00110    01110    11110    00100    01100

Viking VPN Security Blog Rollup


Mega

We will start off with one of the biggest stories of this year. The launch of Kim Dotcoms Mega. In a response to the government takedown of Megaupload, Kim Dotcom and an army of lawyers and security experts have developed Mega, located at Mega.co.nz. The site is quite ingenius in its application, because contrary to Megaupload, Mega does not have access to users data in any digestable form. Even the administrators of the site cannot decrypt the data stored on their servers, because it is encrypted client side before upload, and the key to decrypt the code is not stored on the servers.

This in essence absolves Mega of any responsibility for the sites content. It is controlled entirely by the users, who agree not to pirate anything when they sign up for an account.
