Cisco Advanced Malware Protection (AMP) Threat Grid Sandboxing
Cisco AMP so called as Advance Malware Protection is a term used for Malware file detection technology. AMP will provides you threat intelligence and analytics, point-in-time detection, continuous analysis, and retrospective security of malware files
AMP- Advance Malware Protection can be used at various levels of the network. It can be used as Threat Grid, Endpoints, Network. These all products actually make up an architecture and is not just a different products in the cisco portfolio.
In my earlier post i wrote about the Cisco AMP product for endpoints only. If you want to look that article, please go through the below link

When the Internet (Officially) Became the Public Square
Sometimes, well-intended efforts to prevent unacceptable behavior run into the reality of what it means to have an open and free society. That is what happened at the Supreme Court on Monday.
The Supreme Court issued an opinion confirming something we at Cloudflare have long believed -- that the First Amendment protects access to the Internet. Using sweeping language, Justice Kennedy compared internet access to access to a street or park, "essential venues for public gatherings to celebrate some views, to protest others, or simply to learn and inquire,” and concluded that "to foreclose access to social media altogether is to prevent the user from engaging in the legitimate exercise of First Amendment rights."
We share this view of the internet as a forum to discuss and debate ideas, and believe that the Court’s opinion is an important reaffirmation of the free speech principles we support.
The Packingham Case
Like many other First Amendment cases, the law at the heart of the Packingham v. North Carolina case presents complex questions about how to protect the community in ways consistent with the right to free speech.
In 2008, North Carolina passed a law making it a Continue reading
Switching Basics : Private VLANs
Today I am going to talk about “Private VLANs”. By using Private VLANs you can restrict the specific port from the network and it can only communicate with the uplink port with which it connects.
We have two kind of VLANs; One is Primary VLAN and other is Secondary VLANs. Primary VLANs is a type of VLAN which is used to forward frames downstream to all Secondary VLANs.while Secondary VLANs are further divided in to the 2 types and these types are :
Isolated VLANs :
As name suggested, it is isolated from all the port except the ports in the Primary VLAN or you can say the isolated VLAN port can only talk with the uplink port and will be isolated from the other ports in the network.
Community VLANs:
As name suggest. if two ports are in the community they can talk to each other and talk to the uplink port as well but not able to talk to the other members of the VLANs. They are restricted to have a communication with the isolated VLANs in the network.

Most common question what i am thinking now;
If two different Ports Continue reading

IPv4 route lookup on Linux
TL;DR: With its implementation of IPv4 routing tables using LPC-tries, Linux offers good lookup performance (50 ns for a full view) and low memory usage (64 MiB for a full view).
During the lifetime of an IPv4 datagram inside the Linux kernel, one
important step is the route lookup for the destination address
through the fib_lookup() function. From essential
information about the datagram (source and destination IP addresses,
interfaces, firewall mark, …), this function should quickly provide
a decision. Some possible options are:
- local delivery (
RTN_LOCAL), - forwarding to a supplied next hop (
RTN_UNICAST), - silent discard (
RTN_BLACKHOLE).
Since 2.6.39, Linux stores routes into a compressed prefix tree (commit 3630b7c050d9). In the past, a route cache was maintained but it has been removed1 in Linux 3.6.
Route lookup in a trie
Looking up a route in a routing table is to find the most specific prefix matching the requested destination. Let’s assume the following routing table:
