Secure Socket Layer

Introduction:

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.

Conclusion:

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.

Bandwidth Monitoring Tool

Bandwidth is a key factor in the networking and also an important aspect of the businesses through internet. It is very important to keep a track of the bandwidth usage. ISP keeps a track of this bandwidth usage, but more bandwidth is used which provides a room to compensate this purpose. This tool offers an effective bandwidth control solution that makes the bills of ISP more predictable. The customers are allowed to monitor their own bandwidth usages. It can manage the bandwidth graphs with prevention to the flooding issues. A through monitoring is done along with the severs or network performance. It eases the control of the bandwidth usages that reduces Internet Service Provider bills.

Working of flowmonitor:

  1. xFlow Monitoring:
  • The bandwidth can be measured with the help of IP address or by the application in a network with the help of xFlow where IPFIX protocols are included. These act as a best choice for the networks with very high traffic.
  • This xFlow monitor tool is grouped with the information of bandwidth usage data and sends this information after aggregation to the PRGT with the help of UDP packets.
  • The sampling of any information will send only about the n-th packet to PRTG in order to reduce the CPU loads. As the pre-aggregation it is performed by the switch of the traffic data, the flow data is much smaller in PRGT than the traffic that is monitored.
  • This differentiates the bandwidth usages by the network and IP address.
  1. Net flow and IPFIX Monitoring:
  • This is mainly used in the Cisco devices. If the router is configured once, then the each data flow information is sent to the monitoring system.
  • It is easy to filter and evaluate the data with the help of available Net Flow and IPFIX sensors.
  • The basic ones are pre-defined with channel definitions by means of the customized variants that enable for the definition of the own channel. It generates little CPU load on the router and generates less CPU load on the core system when compared to the sensors of the packet sniffers.
  1. SFlow Monitoring:
  • It is just similar to the Net flow monitoring. The data flow packets data is sent to the monitor system that runs on the PRTG probe.
  • It offers less data to analyze, that offers fewer loads on the CPU and offers less traffic monitor on the data generated.
  • It clearly offers a good insight of the bandwidth usage of the networks.

Features:

  1. Real time monitoring:

It is a tool that provides the current bandwidth usages of each SNMP configured interface. The graphical representation will provide a clear visibility of the bandwidth usages of the specific network interface.

  1. Agentless monitoring:

SNMP is used to retrieve bandwidth details along with its utilization from the available network devices and related routers, switches and other gateway servers. The collected data is presented and correlated in the form of graphs and related tables. No hardware probes are required to get the bandwidth details.

  1. Historical bandwidth trend usages:

The bandwidth utilization trends are used to show the patterns of usages and network traffic trends across a specific period of time. These statistics will help to analyze the bandwidth in the network usages.

  1. Threshold based altering:

Thresholds can be set for the bandwidths and their utilization that offers alerts and emails when the traffic utilization limit exceeds. This is a quicker isolation solution for the network problems.

  1. Monitoring reports:

This tool offers the information about the bandwidth trending on hourly, daily, monthly and also yearly basis and provides information about utilization of the volume, speed and transfers of the packets. Export bandwidth reports are offered in XLS format. Service Level Agreement is also verified with this tool.

Monitor Network Activity

Everyone wants like to be perfect and that the problems would find solutions to itself. Unfortunately that is not the case. Likewise, every manager or higher authority wants his subordinate or sub employee to be honest and dedicated to his/ her work. But in real life situation, it is not always and in most cases, not possible. Therefore often it becomes the sole responsibility of the higher authority or the manager to inspire or take strict measures, to bring out the best out of his employees or subordinates. But being human, the employees also have weaknesses and inattentive moments, which lead to unproductive results often, creating a lackadaisical working environment. For averting such situation the managers should deploy productivity enhancement measures in the respective organization.

Likewise, essential to computer and networking is network monitoring which is primarily designed to track network and its activity on a regular basis. Slow or failing components are detected automatically through system monitoring on a regular basis and by notifying the system administrator, an immediate response is used. Notifications are usually emailed is the system is software based, or else if it is hardware based then physical alarms are used instead.

The level of effectiveness and the efficiency of a monitoring system depend on both the software and the hardware components of the system, which are integrated into the system. There is a limit put by the hardware unit of the monitoring system on how well the system captures the system with respect to the network activity. Nowadays state of the art hardware components are used that can capture accurate readings and allow capture of high speed packets which travel at up to ten gigabytes per second. Even at this rate, monitoring can be applied on the whole system at a single centralized facility.

Another important aspect cum feature of the monitoring is that actual recording of the monitored activities. Generally a storage capacity of at least 2 terabytes is required a small network of computers, but the write to disk speed must be at least 500 megabytes per second. Nowadays 32 terabyte storage capacities with writing speeds of about 7 gigabytes per second are used for bigger scale computer networks.

The Monitoring software is also equipped with accompanying hardware. To provide the design and interface to the administrator an application suite is used, and an application dock for third party software.

The hardware for monitoring can also be integrated into the system without the need for a dedicated storage space. This is because nowadays several models are developed such way that they don’t need any disk storage space for monitoring network activity. However it is ideal for response systems and real time monitoring. It has the same number of ports as the other models but is a low cost and better option aiming at smaller models and at companies with smaller budgets.

To sum it up, the network monitoring tools are an integral part of a computer network. Therefore the hardware must easily and seamlessly integrate with software which comes either pre-installed or as a third party software. A custom operating system also helps a long way!
