Secure Socket Layer


Secure Socket Layer is abbreviated as SSL, is a standard security technology to establish an encrypted link in between the server and a client that is a web server and a browser or in between the mail server and a mail client for example outlook.

It allows the sensitive information such as login credentials, social security numbers and credit card numbers to be transmitted securely. The data can be sent in between the browsers and the web servers in the form of plain text. The SSL allow client server applications to communicate across a network in the way that is designed to prevent the damaging and eavesdropping. It has an ability to keep the message or data confidentially and the message authentication codes for message reliability.

What is Secure Sockets Layer (SSL)?

Secure Sockets Layer (SSL) is a security protocol that determines the variables of the encryption for both the data and the link which are going to be transmitted. It secures millions of people’s data on internet daily, especially at the time of online transactions or when the user wants to transmit the confidential information.

SSL Fundamentals:

There are 3 important elements such as the protocol for communications that is SSL, credentials to establish identity that is SSL certificate and the 3rd party that the vouches for credentials that is the certificate authority.

  • Many of the computers use protocols to allow the various systems to work. The web browsers and the web servers rely on the SSL protocol to enable the encrypted communications.
  • The credentials are useful to establish an identity. The SSL certificate is one type of digital certificate that assists as a credential in online world. Each SSL certificate is identified with a specific domain and a web server.
  • The certificate authorities have a variety of the methods to verify the information that is provided by the organizations or individuals. The established certificates authorities such as the Thawte as well as trusted by the browser vendors.

What is Secure Sockets Layer (SSL) Certificate?

The certificate of the Secure Sockets Layer (SSL) consists of key pair that is public key and a private key. Both keys (public key and a private key) work together to create an encrypted connection. It also contains the subject that gives identification to the certificate or website owner. In order to get the certificate the user need to create a Certificate Signing Request (CSR) on the server. This process establishes a public key and a private key on the server. CSR data file that the user send to the SSL certificate issuer that contains a public key. The certification Authority never sees the private key and uses the CSR data file to establish the data structure to match the private key without any compromising the key itself.

Once the user receives the SSL certificate then they install it on the server. They can also install the pair of intermediate certificates that create the credibility of the SSL certificate by binding it to the CA’s root certificate.

How it works?

First the browser attempts to connect to the web site that is secured with SSL. The browser send request to the web server for the identity itself. Then the server sends a copy of the SSL certificate to the browser. After that the browser checks whether it trusts an SSL certificate and then it sends a message to the server. Then the server sends return a digitally signed acknowledgement to begin the SSL encrypted session. The encrypted data is shared in between the browser and the server and the HTTPS appears.


The Secure Sockets Layer and the Transport Layer are an integral part of web browsers and web servers. The Web server is enabled with the use of Netscape’s SSLRef program library that can be downloaded for the noncommercial purpose or licensed for commercial purpose. It is a commonly used protocol that can be used to manage the security of the message transmission on network.

Why It Is Vital To Use A Security Monitoring Tool For The Business Activities

Monitoring the business network activities is very important for all business owners today. There might be many reasons for this. First of all the activities and transactions would be secured from all kind of external threat. Secondly it is significant to monitor the business activities. This is why the security network monitoring tools are not only important for big companies but for small ones as well. Today the small businesses do also host their own network so its monitoring becomes importantto ensure that the network system is safe from the intruders.

Today the network and Internet is growing at an unknown rate. This prompted the need for network protection otherwise intruders can do their work easily. Today business network activity monitoring has also become importantin order to ensure proper growth. Monitoring all the aspects and resources of a network is also important today. When it comes to an extended enterprise network, it becomes even more important to monitor its security. Hence the network security monitoring tools arevital. They are easily available on NM tools. Security is usually concerned on several level of a network. However it is possible to be done only by the administrator of the network. Remote monitoring service is used by them through some of the dedicated security monitoring software. It can achieve the objective of monitoring network security.

Below are the points which should be considered for monitoring by the good business network security monitoring tools.

Ensuring perimeter security

Perimeter security is a foremost point of security. Any external entity must have to pass through it in order to be able to intrude in the network. This is why it’s an important network security point to be considered. This problem can occur generally if the source or destination packet belongs to some external network. In order to ensure the perimeter security the security monitoring tools are used. The security software is installed on external routers and the firewalls for perimeter security. One can purchase them easily from the company NM tools. We provide competitive tools of network security.

Ensuring transaction and monitoring security

Transaction security is supposed to prevent the network from the major problems like non repudiation, authentication, integrity, virus detection and confidentiality. These are the five major transaction security parametersprovided by good security monitoring tools.

The monitoring security provided by the security tools is supposed to administer various security attacks and unusual network events. The security monitoring tool from the company NM tools can be used to monitor the real time threats as well.
