In Introspection

So far, we've been discussing how to protect end points in the SDN architecture. One very crucial and important aspect of SDN we need to address is the security of controller. There have been many attempts to secure the communication end points in the past which has resulted in various successful results. The research papers we have reviewed in the previous posts and SIEM tools are just a few examples. It seems like most of the research thus far has concentrated on end points and almost nothing on securing the controller of the SDN architecture. This paper addresses how the progress of controller security has fallen behind.

Why is this crucial?

The SDN controller knows everything about the network that allows it to control the network. Imagine if this information gets into the wrong hands. Disaster would be an understatement. Although the consequences are this bad, security of controllers have not been given the attention they need. Thus, the following posts in the blog will be regarding controller security, what threats are most common and how to address the same.

Day 12: Master Slave SDN Controller Architecture

In the previous post, I was struggling to figure out why all controllers can install flows in all switches irrespective of the code. Well, today the mystery is getting resolved. I found this book that explains beautifully the various roles that a controller can play. The three roles are: Equal : this happens by default all the equal controllers in a network that are connected to the switch can add and delete flows from it Slave: it has a read-only limitation to the switch openflow tables Master: very similar to the switch, but only 1 master can be connected to the switch at that point of time, and no other flows can intercept the communication between switch and master. I highly recommend you go through the above link to get a better picture. Since the default role of any controller is "Equal", we couldn't really differentiate between the three controller flows yesterday. But one good news from this is that we don't really need extensive coding to assi...

Day 1: Understanding Ransomware and how to detect them?

Image
To start this journey, let’s begin at the basics and learn about what ransomwares are, what is the meaning of a ransomware attack, how have other people detected it so far? By learning the above, we will be in a position to analyze any ransomware attack and devise methods to detect, mitigate and prevent them. Definition: Ransomware is a type of malicious software from cryptovirology that threatens to publish the victim's data or perpetually block access to it unless a ransom is paid. To continue understanding and addressing the threats posed by ransomware, let us dig a little deeper. As the definition specifies, ransomware is a type of malicious software. Now, what is a malicious software? Definition: Malware (= Malicious + Software) is a software which is specifically designed to disrupt, damage, or gain authorized access to a computer system. These malwares (or simply dangerous content that can corrupt your system), can enter your system from various s...

Day 50: Tcpreplay and tcpliveplay approach

Today we shall be exploring how to copy and redirect the OpenFlow packets to more than one controller from the load balancer. The load balancer is anyway sending the OpenFlow packets to one of the slave controllers - c1 or c2. The packets sent to these two controllers needs to be sent to master controller so the master controller can update the new flows added by c1 or c2 on the switches. This ensures synchronization between controllers. There are two implementation methods to achieve the same: Copy all packets generated from the load balancer to the controller side. Only the packets having destination IP address of c1 and c2 can be redirected to the master controller. Thus we can prevent the packets which already are reaching the master controller to be sent as duplicates Copy and redirect packets from the slave controllers - c1 and c2. We need not take care of duplicate packets reaching master controller. This will reduce the time taken to redirect packets. Since the second a...
