With the increasing usage of internet in our everyday life, we are starting to feel the backward of searching engine. The engine sometimes does not serve us accurate outcome and often treated by spam. Since it is operated by engine, the engine is only helping us by matching key keyword and not able to give effective filter to dangerous websites. Unlike the searching engine, web directory is listed and operated by human. The web directory will give accurate outcome for visitors because all the websites are classified based on its category. Web directory is also able to protect us from dangerous websites because all the websites that were submitted must through the approval phase.

The most popular web directory that we can visit is Yahoo directory. There, we can directly choose the website category we need and directly search for specific subject we want. The web directory is not only advantageous for visitors, but also for webmaster. With the web directory, webmaster can get their target market or increase their selling rate.

There are paid and free web directory, and the free directory that webmaster can choose is DMOZ. There, webmaster can easily submit their websites and if they have passed the approval phase, the website will be directly listed on the web directory. Another reputable web directory service is Jasmine directory that can be visited on Jasminedirectory.com or Max directory. All web above directory very recommended to you business owners when you seek to improve your link popularity and increase your business web site traffic and the final goal is increase your business profit. To maximize the advantages of web directory for your business you must submit your business to the right categories. So invest your time and budget to submit your business web site to as many web directories as you can to collect huge relevant links to your business.

Many people are reluctant to shell out the cash for decent antivirus software. I’ll agree that at roughly $50 for a decent antivirus program, it isn’t exactly small change. But, let’s look at the costs more closely for a moment:

Computer –> $600-$4,000
Monitor –> $250-$1000
Software –> $500-$5000
Internet Connection –> $25+/month
Personal/Business Data –> Priceless

So, on the low end of the scale we are looking at a computer investment similar in price to an older used car, on the higher end, similar to a newer used car. Having a computer that does not have up-to-date antivirus protection is absolutely the same. You are simply asking for trouble.

Simply because that is what viruses, worms, malware etc. are made to do. Their ONLY job is to find unprotected computers and attack and hijack them without your knowledge. If your computer isn’t protected, and you share disks or go online, it will get infected.

The top antivirus software programs cost as little as 2 months internet connection. They all include constant and unlimited automatic updates that keep your system safe and clean.

If you can afford $1500+ on a computer, $300+/year on internet connections, you can definitely afford another $50 once to make it safe (and prevent it from being used to spread viruses and Trojan horses behind your back).

In business one of the top priorities is internal security. Through computer use, corporate information can easily be compromised if an organization does not have a proper spy software system in place. By tracking employee activity, a well-developed spy software system allows administrators to have control over all computer activity while preserving the privacy of all internal data. SONAR is a revolutionary security spy software product that helps administrators maintain the integrity of their company by protecting critical information and enforcing internal policies to all network users. This advanced spy software creates a coherent system that functions at the desktop level.

SONAR’s spy software monitors all online activity through a central server that governs assets on or off the company network, including outside contractors and traveling sales people. With SONAR, security solutions are configured in minutes making this spy software one of the most user-friendly on the market. SONAR’s advanced spy software system captures all keystrokes that have been typed into a computer. SONAR takes screenshots of all computer activity, past and present, reads all employee communications, blocks software applications on a scheduled basis, screens all email attachments for sensitive material, and tracks all file use.

SONAR allows compromising material to be blocked and will remotely destroy or locate any recovered data when appropriate. With SONAR’s advanced filtering capabilities you can block websites, filter content, create a white-list of websites allowed, whereby traffic is directed to these sites only, and limit application of use according to your specifications. In addition, SONAR offers spy software functions as an ultimate surveillance tool, providing proof for investigations that may be conducted as a result of inside company fraud.

With SONAR spy software the technology is analyzed internally, allowing the risk of security breaches to be nipped in the bud. Often precious time on the job is wasted by unnecessary web surfing. More than 2/3 of Internet users have confessed in interviews that they have wasted sometimes more than 30% of their job time in non-work-related Internet surfing, whether browsing shopping sites, porn sites, or hobby-related sites. With SONAR spy software this activity is not only monitored but can also be instantly curtailed.

SONAR spy software has the unique ability to identify, track, and control data output, providing a specific protocol for what can be done and what cannot be done with company material. Any application can also be deployed at the discretion of company administrators in a matter of minutes making SONAR one of the most pliable, efficient, and thorough spy software programs on the market today.

Computer theft has also become a commonplace occurrence in the business world. Losing even one computer can compromise the entire security of an organization. Corporate spy software programs are designed to maintain, secrets, safeguard intellectual property and provide security through monitoring all computer activity - both on- and off-site.

For many information system based on DBMS it is often a problem to implement access restriction, which takes information value into account. It is usually crucial for large-scale information systems of government or corporate use (i.e. geographical information systems or document management systems). Such system usually imply mandatory access model. One of the features of the mandatory model is prevention of either intentional or accidental decrease of information value thanks to information flow control. Mandatory access model is implemented by labeling all the subjects and objects belonging to the access restriction system.

Oracle DBMS is currently one of the most powerful and popular industrial DBMS. Starting from Oracle9i version, Oracle Label Security (OLS) component is implemented, which makes it possible to organize mandatory access to stored data. OLS is a set of procedures and limitations built into database kernel, which allow implementation of record-level access control.
Analysis for possible leakage channels of confidential information seems interesting for the reviewed system.
We are offering the following common analysis algorithm of the implemented mandatory access model.

1) Access object types are determined according to the published documentation and investigation of the DBMS (e.g., tables, strings, or columns).
2) Commands of SQL are analyzed in terms of how users can modify access objects.
3) Several objects with different confidentiality levels are created for each access object type.
4) Several user (access subject) accounts are created with different mandatory access rights.
5) A sequence of SQL-queries is formed, which are executed with different mandatory access restriction rights and objects with different confidentiality level.
Let us consider access objects in OLS. These are table records, which have

unique labels. It is often implied that tables are access objects in OLS because security policy is applied to tables. However tables do not have labels themselves; they just contain labeled rows.
The following basic SQL operations handle individual records:
- CREATE – creation of a new record;
- SELECT – reading of an existing record;
- UPDATE – modification of an existing record;
- DELETE – deletion of a record.
Our experiments consisted of sequences of queries called by users with different mandatory access rights to objects of different confidentiality levels. These experiments made it possible to construct the mandatory access model of OLS to records. We define two variables: I and J. I is a value of object’s label. Smaller values of I indicate higher confidentiality level (the value of 0 corresponds to “top secret”). J is a value of subject’s access level.
The model can be presented in the following formalized view:

1. CREATE \ SELECT \ UPDATE \ DELETE, j = i
2. SELECT, j i

Such mandatory access model on record-level is quite correct and it meets criteria of Bell-La Padula security model. So OLS works correctly on the level of table records.
However, beside records as representation of stored data, users can interact with other data representation, which are not affected by the mandatory access policy. Tables are an example of such objects. Users indeed can modify structure of tables, i.e. add new fields, change their names, and modify data types. OLS loses its ability to work properly on table level.
For instance, a user with higher mandatory rights has a right to create a new field in a table. The name of the field may be confidential itself, and OLS mechanism does not prevent this operation. A user with lower access rights has always a possibility to query names of all the fields.
For example, a new field is created with the name new_password_xxx (where xxx is a top secret information) with the following sql-query:
ALTER TABLE user1.test_table ADD (new_password VARCHAR2(30));
If another user who does not have any mandatory rights executes the following query (SELECT * FROM user1.test_table; ), he gets an empty data set, however all field names ofuser1.test_table are exposed to him. As it was shown above, column name can contain classified information.
Operations shown in the example create duplex channels of data exchange between subjects with higher and lower access rights, and therefore they can cause leakage of classified information.

In the issue of the foresaid, the mandatory access model implemented in Oracle is not complete, and this fact makes it possible to exchange classified information without any control of the mandatory access system, which decreases information value.
