Five signs an attacker is already in your network
This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.
According to some estimates, attackers have infiltrated 96% of all networks, so you need to detect and stop them before they have time to escalate privileges, find valuable assets and steal data.
The good news is an attack doesn’t end with an infection or a take-over of an endpoint; that is where it begins. From there an attack is highly active, and the attacker can be identified and stopped if you know how to find them. These five strategies will help.
* Search for the telltale signs of a breach. Look for port scans, excessive failed log-ins and other types of reconnaissance as an attacker tries to map out your network.

Moscow, Russia: CloudFlare’s 83rd data center
Здравствуйте! ))) CloudFlare is excited to announce the newest addition to our network in the largest country in the world (by footprint), increasing both our data center and city count to 83. Moscow is not only the capital and largest city in Russia, it is also home to several Internet exchanges which CloudFlare now participates at: the Moscow Internet Exchange (MSK-IX), Data IX and Global IX (Eurasia Peering coming soon). This raises the number of exchanges that CloudFlare is a participant of to over 120, making us one of the top interconnected networks globally.
Здравствуйте! ))) Мы рады объявить о новом пополнении в нашей сети network в самой большой стране мира (по занимаемой площади), увеличивая как количество наших датацентров, так и количество городов на 83. Москва является не только столицей и самым крупным городом в России, но она также является домом для нескольких точек обмена интернет-трафиком. CloudFlare в настоящее время принимает участие в следующих: Moscow Internet Exchange (MSK-IX), Data IX и Global IX (Eurasia Peering на подходе).

DNS Cookies and DDoS Attacks
DDoS attacks, particularly for ransom—essentially, “give me some bitcoin, or we’ll attack your server(s) and bring you down,” seem to be on the rise. While ransom attacks rarely actually materialize, the threat of DDoS overall is very large, and very large scale. Financial institutions, content providers, and others regularly consume tens of gigabits of attack traffic in the normal course of operation. What can be done about stopping, or at least slowing down, these attacks?
To answer, this question, we need to start with some better idea of some of the common mechanisms used to build a DDoS attack. It’s often not effective to simply take over a bunch of computers and send traffic from them at full speed; the users, and the user’s providers, will often notice machine sending large amounts of traffic in this way. Instead, what the attacker needs is some sort of public server that can (and will) act as an amplifier. Sending this intermediate server should cause the server to send an order of a magnitude more traffic towards the attack target. Ideally, the server, or set of servers, will have almost unlimited bandwidth, and bandwidth utilization characteristics that will make the attack appear Continue reading
