Hi Friends...Freelancing is tough. It can be very difficult, in fact. It can wear people down, making them lose sight of what they used to love because they have to do everything else just to get by.

Unified Threat Management Systems - Guide to UTMs

Hi folks..this time I will be exploring the Unified Threat Management systems and comparing multiple UTM products in the same. Unified Threat Management devices are relatively new in the security appliance scenario and are in the phase of continuous evolution. UTM has attracted industry leaders like Juniper, Fortinet, Cisco, IBM, Intel, Cyberoam and there are a lot of UTM products to choose from. I am however working on the Cyberoam one and will be continuing my tests on it.

Top Indian Hackers List

There has been a lot of commotion in the Indian Hacking scene lately, and I expressed some pretty strong views regarding that. When it comes to hacking, every other guy tends to tape the "hacker" word with his name/codename without even realizing its significance. In the end tired of all the bullshit around, I decided to cover an article on the REAL INDIAN HACKERS (or Hackers of Indian Origin), folks who are actually dedicated to security and are hackers in real sense. Lets start, shall we ?

Top Hacking Magazine List with Review

Except these Magazines, all other so called Indian Hacking magazines are BOGUS and copy pasting contents from INTERNET. Wake up GUYS. Simple ask your self that are you really learning something from what you are reading or not?. This time I will be blogging about some really good magazines and zines where you can learn about computer and IT security. If you want to go through the previous articles in the series, you are welcome to give them a read.

Yersinia: How to analyzing and testing Network Protocols

Yersinia is a free open source utility written entirely in C which is great for security professionals, pen testers and hacker enthusiasts alike. Yersinia is a solid framework for analyzing and testing network protocols, and it is a great network tool designed to take advantage of some weaknesses in different network protocols.

What is Network Functions Virtualization (NFV) - Virtualizing Network Functions

9:52 PM Amarjit Singh No comments
Network Operators networks are populated with a large and increasing variety of proprietary hardware appliances. To launch a new network service often requires yet another variety and finding the space and power to accommodate these boxes is becoming increasingly difficult; compounded by the increasing costs of energy, capital investment challenges and the rarity of skills necessary to design, integrate and operate increasingly complex hardware-based appliances. Moreover, hardware-based appliances rapidly reach end of life, requiring much of the procuredesign-integrate-deploy cycle to be repeated with little or no revenue benefit. Worse, hardware lifecycles are becoming shorter as technology and services innovation accelerates, inhibiting the roll out of new revenue earning network services and constraining innovation in an increasingly network-centric connected world. Network Functions Visualization(NFV) aims to address these problems by leveraging standard IT virtualisation technology to consolidate many network equipment types onto industry standard high volume servers, switches and storage, which could be located in Datacentres, Network Nodes and in the end user premises. We believe Network Functions Virtualisation is applicable to any data plane packet processing and control plane function in fixed and mobile network infrastructures. NFV decouples the network functions, such as network address translation (NAT), firewalling, intrusion detection, domain name service (DNS), and caching, to name a few, from proprietary hardware appliances so they can run in software. Virtualizing Network Functions could potentially offer many benefits including, but not limited to:
  1. Reduced equipment costs and reduced power consumption through consolidating equipment and exploiting the economies of scale of the IT industry.
  2. Increased speed of Time to Market by minimising the typical network operator cycle of innovation.
  3. Availability of network appliance multi-version and multi-tenancy, which allows use of a single platform for different applications, users and tenants. This allows network operators to share resources across services and across different customer bases.
  4. Enables a wide variety of eco-systems and encourages openness.
