The Advantages of Authentication

There are numerous advantages of authentication systems which are used to identify the user of a home, ATM or a security clearance computer system. The main purpose of these systems is to validate the user's right to access the system and information, and protect against identity theft and fraud. While there are still drawbacks with some systems, as the business world and the electronic marketplace become more complex, the advantages of authentication are ever more obvious.

Password Based Authentication
The use of a password and username is the most common form of authentication used and is generally considered the cheapest and most convenient method. This requires the user to provide and remember a key containing a specified amount of alpha and numeric characters in relation to a username or e-mail address which must be correct at each login. Passwords saved on a network can be encrypted to prevent theft by employee or programs designed by hackers.

Implementing Core Cisco ASA Security (SASAC)

  ASA uses a security level associated with each interface. It is a number between 0 to 100 that defines the trustworthiness of the network that the interface is connected to; the bigger the number, the more trust you have in the network. For example, the most secure network, such as the inside LAN, should have the security level of 100. The outside network connected to an untrusted network (such as the Internet) should have the level of 0. The interface connected to the DMZ should have the security level set to somewhere between 1 and 99 (usually 50). Security levels are used to define how traffic initiated from one interface is allowed to return from another interface. By default, the higher level security interfaces can initiate traffic to a lower level. The stateful inspection determines whether the reply traffic is allowed to make it back through. The following picture illustrates the concept: level 100 for the inside network level 50 for the DMZ network level 0 for the outside ne

Netware Makes a Splash

During this period, several operating systems were developed, like IBM's MVS operating system, which still dealt with SNA. However, the development of another operating system, dubbed UNIX, really paved the way for NOS everywhere. After a project to develop a large and complex system called Multics failed to get off the ground at Bell Labs in 1969, a group of Bell researchers, led by Ken Thompson and Dennis Ritchie, started work on a less ambitious but no less powerful computing system. After a rocky first few years, Ritchie developed the C programming language, which allowed UNIX to become the first "portable" operating system, meaning it could be implemented on any computer system. The relative simplicity of the system's design and the availability of its source code turned UNIX into a darling of the academic world and a fixture on many university computer networks. Many versions of UNIX were developed, but the Berkeley Software Distribution (BSD) version, develo

How CrackStation Works

CrackStation uses massive pre-computed lookup tables to crack password hashes. These tables store a mapping between the hash of a password, and the correct password for that hash. The hash values are indexed so that it is possible to quickly search the database for a given hash. If the hash is present in the database, the password can be recovered in a fraction of a second. This only works for "unsalted" hashes. For information on password hashing systems that are not vulnerable to pre-computed lookup tables, see our hashing security page. Crackstation's lookup tables were created by extracting every word from the Wikipedia databases and adding with every password list we could find. We also applied intelligent word mangling (brute force hybrid) to our wordlists to make them much more effective. For MD5 and SHA1 hashes, we have a 190GB, 15-billion-entry lookup table, and for other hashes, we have a 19GB 1.5-billion-entry lookup table. Read more :  lm hash generator
