Secure Socket Layer ( SSL ) is a security protocol that was developed by Netscape Communications Corporation , along with RSA Data Security, Inc. The Primary goal of the SSL protocol is to provide a private channel between communicating applications, which ensures privacy of data, authentication of the partners, and integrity. The Secure Socket Layer (SSL) technology was used for the websites or web applications which need more security.  SSL handshake protocol with two way authentication with certificates. (Photo credit: Wikipedia )   Secure Socket Layer (SSL) is composed of two layers: At the lower layer, a protocol for transferring data using a variety of predefined cipher and authentication combinations, called the SSL Record Protocol. On the upper layer, a protocol for initial authentication and transfer of encryption keys, called the SSL Handshake Protocol. An SSL session is initiated as follows: On the client (browser), the user requests a document with a special UR...

English: Encapsulating one IP packet in another IP packet (Photo credit: Wikipedia ) Internet Security is the securing web server and client (browser) from the possible attacks over the Wide Area Networks or Internet. Internet security is a type of Computer Security or the network Security. It includes mainly specific security protocols like IPSec (Internet Security Protocol), SSL ( Secure Socket Layer ) or TSL (Transport Layer Security). Internet Security also describes about PGP ( Pretty Good Privacy ) which is designed to create authenticated and confidential e-mails. It also discuss about Firewalls and Antivirus Programs. # IP Security (IPSec) IP Security (IPSec) is collection of protocols designed by Internet Engineering Task Force (IETF) to provide security for a packet at the network level. It helps to create authenticated and confidential packets for the IP layer. IPSec operates in one of the following two modes. i) Transport Mode In this mode, IPSec protects what is delive...

      A relational database management system (RDBMS) is a database management system (DBMS) that is based on relational model. It is the information that is stored database is related to import and export information each other. It acts as an interface between the user and the data. It ensures that the data is kept in a compact and consistent format, and allow the user to ask a wide range of questions about the data. A DBMS can be described by the view of the data it presents to the user.   Key terms used in RDBMS Query: A query is a small command or program given to a database system instructing it how to manipulate some data from a database. Example: SELECT * FROM tbl_std; Relation: A relational database consists of a set of two-dimensional tables termed relations. All the data in the database is contained entirely within such tables. Each relation in the database has a unique name so that it can be identified. Example: An example of relation is sho...
