A walk down Telecom Security Testing on IP TVs: What is IP TV? IPTV is one of the emerging technologies that provides IP-based digital TV, video-on-demand, and streaming services over the Ethernet. A more enhancement over IP TV is the “Fiber to the Home” (FTTx) and “Local Loop Unbundling” (LLU) enhancement. Most of the service providers offers this as a package which is referred to as triple play services including (Data, Voice and IPTV). The feature is served to home connections over a single broadband transmission medium. On a quick note, it is useful to note the classification of IPTV services in the four broad types: ·          Live television / live media - With/without related interactivity ·          Time-shifted  media : C atch-up TV  (which allows replaying a TV show, start-over TV (replays the current TV show from its beginning); ·          Video on demand  (VOD) : browse and view items in a stored media catalogue. ·          Interactive applications :

Security Testing on Block Chain: By- Samrat Das Now since we have our fundamentals clear on block chain, let’s proceed for understanding the security concepts of block chain penetration testing: Even though block chain is secure with lots of conceptualized security controls, there are quite a few places where an attacker can extract information or attack the nodes. A few of such attack vectors are: ·          Block chain permissions escalation ·          Crypto Key Tampering ·          Inappropriate consensus mechanism ·          Lack of block chain security program plan ·          Lack of block chain integrity ·          Lack of malicious code protection ·          Misused timestamps ·          Genesis block tampering ·          Denial of service (DOS) attacks ·          Packet sniffing & MITM attacks In order to perform a holistic review of Block Chain Technology, we can break our assessment step to four parts: ·          Design review w
