Duty of firewalls 2007-08-28 15:36:19 PEM counters the threat of onterception or tampering with amessage stream in electronic mail. Although that is a significant concern, there is limited use of electronic mail for sensitive communication. More significant is the threat that an untruder would penetrate a ststem turm connected to the Internet. This threat is more significant for two reasons: an electronic message contains very little data, usuallt only hundreds or thousands of bytea. whereas a network. may be unaware of the threat to all stored data. Thus, protection of network conected resources is very important.The simplest from of protection of sensitive resources is not to connect them to any system accessible from outside the organization's security perimeter, Physical isplation is totally effectibe against outside attack,but manyusers need, and more want, access to the outside.in the worst case, a user woll buy an indezpensive modem and connect it to a LAN-connected workstation to link to the outside. This practice
Symmetric-Key Encryption 2007-08-28 15:35:02 Symmetric-Key encryption (also some times called bulk encryption) is what most people think of as a secret code. The essence of a symmetric-key system is that both parties must know a shared secret. The sending party performs some predefined manipulation of the data, using the shared secret as a key. The result is a scrambled message which can only be interpreted by reversing the encryption process, using the same secret key. A good example of a symmetric-key encryption mechanism was the Enigma system used in World War II. In that case the manipulation was performed by an electro-mechanical machine and the key was a series of patch panel connections. The key was changed at regular intervals, so there was a fresh challenge for the code breakers every few weeks.Using modern computer systems, symmetric-key encryption is very fast and secure.

Java in the World Wide Web 2007-08-28 15:34:24 Java on its own would be just another, rather interesting, programming language. It is when it is combined with the Hot Java Web browser that it really comes into its own. Hot Java is Sun Microsystems browser that contains the Java run-time environment combined with conventional Web browser function. The Java code has been licensed by several other browser manufacturers, including IBM, Netscape and Microsoft (note that Netscape also provides another client-side execution language named JavaScipt, which despite its name is not directly related to Java).Special new HTML tags allow you to specify in a document a small Java program, called an applet to be sent to the browser and executed. The Hot Java run-time environment provides access to the client machine’s facilities, such as graphics, sound and network access. The Java language itself provides object Read more:World
What Is Java? 2007-08-28 15:33:08 Java itself is a programming language, developed by Sun Microsystems. It is object-oriented, and was designed to be a close cousin of C and C++, but easier to program, more portable and more robust. The authors have done an excellent job of removing the features in C++ that give programmers sleepless nights, yet retaining good functionality.The features of Java that are especially important in the Web environment are:Portability Java is a compiled language, but unlike other languages it does not compile into machine instructions, but into architecture-neutral byte codes. This means that the same program will run on any system that has the Java run-time environment, regardless of the operating system or hardware type.Thread Support Java has multithread support built in to it, making it very effective for dynamic applications and multimedia.Memory Managemen
How Secure Is HTTP Basic Authentication? 2007-08-28 15:32:24 With basic authentication, your server has identified who the client user is by means of a user ID and password. How sure can you be that the user really is who he claims to be? To answer this you have to consider the ways in which the ID and password may have been compromised:The user may have voluntarily given the ID to another person.The user may have written down the ID, and someone may be using it without his knowledge.Someone may have guessed the password.Someone may have intercepted the user ID and password between client and server systems.The first three possibilities are problems which occur in any password-based system. The normal response to such issues is to suggest better user education and password rules. This is quite reasonable, and can be effective within a single enterprise, where you have some control over the users of the Read more:Authentication

Using Access Control List Files 2007-08-28 15:30:26 Another method of controlling access to the server is to use access control list (ACL) files. These are files named .www_acl which reside in the directory of the files to be protected. ACL files can be used in two ways:As a secondary form of access control, on top of the protection offered by protection directives in the http.conf file.As the sole form of access control. You still need Protection and Protect directives, because they define the password file to use and the directory to protect. However if you code the following line in the Protection directive, the Mask entries in it will be ignored, so long as there is an ACL file in the target directory:ACLOverride OnAn ACL file consists of a series of lines of the form:file : method : user_or_groupThe file specification can contain wildcards (*) in the same way as the definitions in th Read more:Access

Impotant of computer network security for user 2007-08-28 15:29:05 Memory protection in a multiuser setting has evolved with advances in hardware and system design. Fences,base/bounds register,tagged architecture,paging, and segmentation are all mechanisms cesigned bith for addressing and for protection.File pritection schemes ongeneral--urpose iperating system are offten based on a three or four level format (for example. user group all). This format is reasonably straightforward to implement. but it restricts the granularity of access control to few levels.Access contro; in general is addressed by the access control matrix. or access control lists organized on a per-object or per-user basis. Although very flexible, these mechanisms can be difficult to umplement efficiently.User authentication is a serious isse that becomes evsn more serious when unacquainted users seek to share facilities by means of computer network

Spybot - Search & Destroy .History And Description 2007-08-26 13:24:40 The first known use of the expression "spyware" occurred on October 17th, 1994 in a post that joked about Microsoft's business model. Spyware later came to allude to snoop equipment such as diminutive cameras. In early 2000, the man who started Zone Labs used the term in a press release for a new product. Since then, the computer-community has used the term in its current definition.Spybot - Search
& Destroy can detect and remove a multitude of adware files and modules from your computer. Spybot also can clean program and Web-usage tracks from your system, which is especially useful if you share your computer. Modules chosen for removal can be sent directly to the included file shredder, ensuring complete elimination from your system. For advanced users, it allows you to fix Registry inconsistencies related to adware and to malicious program installations. The handy online-update feature ensures that Spybot always has the most current and complete listings of adware, dialers, an Read more:History
How to Stop Blog Spammers. 2007-08-26 11:21:56 Now anyone can make comments on a particular blog posting. As blog commenting has grown more popular, so has spam commenting. In this newsletter, we’ll go over why comments are a great form of feedback for your blog, how they help the credibility of your content, what spam comments are and how to prevent them from happening.Comments – A great form of feedbackWhen blogs first came around, they were simply online journals. No one could post comments on a blog posting. That all changed in 1998 with OpenDiary, a site which allowed people to comment on blog postings. Now every blog, whether it is remotely or self-hosted, includes this option to comment.Commenting is great because it allows real people to tell you what they think about your form. It gives you feedback on what you are doing right and what you may need to improve. Comments can be encouraging to you and motivate you to post more quality blog messages. Or they can be constructive criticism to make you work harder to get bet
What Is Spam? Is It Such A Huge Problem? How to Stop spam. 2007-08-26 11:20:36 If you have an email address you probably already know what spam is. Essentially spam is the junk mail of the electronic world, and just as if not more annoying.While the meat of each spam message is different, offering deals from everything from dating sites to pornography to prescription drugs, their goal is to sell you something. Spam is sent out by some type of automatic mailer program, sending the same message to you and millions of other email users.Most people find spam so annoying because of the sheer volume. Most people end up with hundreds of junk emails a week, sometimes a day. If your email program doesn't separate or filter out spam, it can take hours to sift through all the garbage and find the emails you're actually interested in.Spam got its beginnings on USENET, which are newsgroups for various topics of discussion. Spam was being sent to multiple groups via cross-posting. Soon spammers were sending advertisements to thousands of different newsgroups, regardless of t Read more:Problem
What is virus Computer? Virus Of Mass Destruction 2007-08-26 11:15:00 Well, the best definition we have been able to come up with is thefollowing1. A virus is a program that is able to replicate, that is create(possibly modified) copies of itself.2. The replication is intentional, not just a side-effect.3. At least some of replicants in turn are also viruses by the samedefinition.4. A virus has to attach itself to a "host", in the sense thatexecution of the host implies execution of the virus.virus may be modified, either by the original author or someone else, sothat a more harmful version of it appears. It is also possible that themodification produces a less harmful virus, but that has only rarelyhappened.The damage caused by a virus may consist of the deletion of data orprograms, maybe even reformatting of the hard disk, but more subtle damageis also possible. Some viruses may modify data or introduce typing errorsinto text. Other viruses may have no intentional effects other than justreplicating.Finally, remember that some viruses may interfere with Read more:Computer
