Access Control Lists (ACL) at Wednesday, February 22, 2017 Posted by nitheesh

Hi Readers, This Post can help you to understand Access Control Lists. Access Control Lists are the list of access control entries which are used to specifically allow or deny rights to any host to enter or exit a network. ACL is a sequential list applied to upper layer protocols in order to posses control in a particular dimension. This material attached (LBN03) has a walkthrough on Access Control List. What ACL is all about, why we need ACL, Functions of ACL, Syntax, Wildcard Masks, Commands and working scenarios. Further Queries, Please contact me. Thanks Click Here for the Link

Biding GOODBYE to my BEST Friend......சென்று வென்று வா நண்பா.... at Monday, February 20, 2017 Posted by nitheesh

நல்ல நண்பன் - வெங்கட்....:
உன்னை பற்றி எழுத வேண்டும் என்று தோன்றியது...
இதோ என் மனதில் உள்ளவை....
மூன்று வருட பழக்கம் மட்டுமே என்றாலும் மதிக்கக்கூடிய, மரபை மீறிய, அன்னோன்னியமான நட்பு நம்முடையது....
இந்த மூன்று வருடங்களில் நமக்குள் கருத்து வேறுபாடு முன்னூறுக்கும் மேற்பட்டது....ஆனால் ஒவ்வொரு முறையும் நீ என்னிடம் சமரசம் செய்வாய்....
எண் கணக்கிட்டு என்னோடு நீ சேர்ந்திருக்கலாம்.....ஆனால் நம் நட்பு எண்ணற்றது.....
முதல் நாள் நான் வந்ததிலிருந்து....இன்று உன்னை வழியனுப்பிய வரை....
நீ எனக்கு சமைத்து கொடுத்தாய்....கார் கொடுத்தாய்....வாங்கிய கடனை திருப்பி கொடுத்தாய்....வாய் உள்ள பிள்ளை பிழைத்துக்கொள்ளும் என்று கத்துக்கொடுத்தாய்....அனைவரிடமும் பொறுமையாக இருந்தாய்....என்னிடம் மட்டும் கடும் கோபப்பட்டாய்....நம்முடைய ரகசியத்தை ரகசியமாக வைத்துக்கொண்டாய்....
You made me comfortable at Botswana...my dear friend...you made me comfortable to share my personal griefs and feelings with you...i did it so many times....Its odd feeling when i bid you good bye at the airport...But all is well....I just want to quote a Kamal's Dialogue to you at this instance from Anbe Sivam Movie, even though I am not cinematic generally, this one will be apt for us with two changed words..
"PARAVAIGALUKKUM THURAVIGALUKKUM NIRANTHARAMANA SARANALAYAM IRUPPATHILLAI..NAANUM (Nalla Natpum) ORU PARAVAI POL THAN..NIRANTHARAM ENUM NILAYAI ASOUGARYAM ENUM KARUDUM.."
Good Bye my friend...will meet in the future....hope this world dies to see us work together again and if that happens, on seeing us again working together...the world will die!!!! My Advice to you: Atleast from now, try to be together with your family. Just for three years i feel the preciousness of your presence in my life...the same way your family might also...they are missing your great presence. Atleast talk to them everyday....End of the day, money is money...dont worry....We can earn that...but not this valuable presence.... Bye Bye...But buddy dont forget...even if we dont work together...thats not a big problem, but invite me when you go to Thailand!!!!

Enhanced Security in Computer Networks based on Multilevel System and User Intervention at Friday, February 17, 2017 Posted by nitheesh

Hi Readers, A detailed study focusing on current security systems implemented in Computer Networks reveals controlling both physical and logical threats which are posed over a network. The existing security systems control the physical and logical threats either with the interaction of users or the automated computer policies set by the system itself using the Internet of Things [IOT], Messaging Services, RFID etc which in a real time world faces practical disturbances and inconveniences in the flow of the work. This paper focuses on combination of user and system interaction, whole together in the course of providing efficient secured network using multilevel system and user intervention which in turn reduces the system or the user’s possibility of false perception in securing the network. The physical network environment threats are measured based on the room temperature, humidity, unauthorized access in the environment etc and those data are calculated with the existing security systems and user-defined metrics. Using these data, securing a network in an efficient manner is quite a challenge for either the user or the system. We propose to analyse the above data with the help of existing perception control systems. The analyzed data works as a Decision Support System [DSS] in deciding the prime factor of security alert posed, possibility of accuracy in the available data and the current scenario of the environment. Based on the DSS analysis, the security alert is initiated in the first level alerting the system itself. However, the system takes only preliminary action by either notifying the user levels about the current scenario through WEB, MAILS, GSM etc or by blocking the present network transactions. In the next level, based on the alert raised by the system, the user matches the existing alert with real time scenario and could confirm the alert level either true or false. Based on the User and the System Intervention, the attack will be confirmed and the network could be shut down or closed. The combined intervention of both the user and the system using the DSS reduces the false perception of network attack and improves the uptime of the network avoiding unnecessary false alerts.

DHCP - Configurations at Monday, January 30, 2017 Posted by nitheesh

Hi Readers, This Post can help you in doing some basic configurations with switches and routers assigning DHCP. DHCP is Dynamic Host Configuration Protocol. Using DHCP is one of the advantage for the System/ Network Administrators, helping to get a control over the network. DHCP will dynamically assign IP Address and Network configurations to the host. DHCP is considered as really a Time saving and resource saving concept. Before working on DHCP Configurations, my advice is to go through the basics of DHCP. This material attached (LBN02) has a topology and the configurations to succesfully make the network to work on DHCP. Additionally, it also goes through INTER VLAN COMMUNICATION and ROUTER ENCAPSULATION. Further Queries, Please contact me. Thanks Click Here for the Link

Welcome 2017!!!! at Thursday, January 19, 2017 Posted by nitheesh

Warm Welcome to 2017!!! I hope, this year is not an "yet another year passing". Positive Thoughts First!!! My resolution is to atleast post 1 article every week in 2017. I can understand that, i have stopped blogging in the year 2016. Lots of reason to quote for that, but still that is not a good sign of growth.
This 2017, as not usual, I am not pledge a list of resolution and then stop to follow it. This time, its only one. Spending more time in writing Articles.
