Application Micro-Segmentation: Securing the Enterprise

© 2016 BROCADE COMMUNICATIONS SYSTEMS, INC. INTERNAL USE ONLY

What is Micro-Segmentation?


Micro-Segmentation“East-west (machine-to-machine) data movement is increasing in volume as workloads become movable and thus more demanding on their infrastructures. At the same time, perimeter-only, firewall-based security has proved weak in a world of advanced cyber-attacks. Evolving security models, such as software-defined and distributed firewalls, are beneficial, but they also create new management complexities. In these environments, IT teams are finding it difficult to deploy a tight approach to security. To improve security profiles, organizations are now turning to techniques such as micro-segmentation to amplify and distribute current defenses. Micro-segmentation divides a network into smaller zones and provides protection by making security adaptive and multilayered. It provisions services closer to the applications, between application tiers and even to the machines within tiers.

Taken from “Micro-Segmentation: A Better Way to Defend the Data Center”; eWeek, Chris Preimesberger; posted July 28, 2015


Benefits of Micro-Segmentation• Zero Trust Security*

In the micro-segmentation model, there is no default trust for any entity—users, devices, applications and network—regardless of placement or location. The entire mechanism is based on denying all communication until explicitly allowed (via explicit policies) and permitting only what is necessary from trusted sources………

• Application-Aware Security*Micro-segmentation policy groups are generally created based on application tiers, workload profiles, placement zones and other factors. They are not based on rigid IP addresses or subnets. Policies also are enforced right at the virtual machines or containers hosting the application tiers. Workloads and data access are secured at the source as an application-centric securitymodel.

• DevOps Alignment*Micro-segmentation allows application owners to be responsible for their own app's security while allowing them to see only what they are entitled to see. This allows operators to analyze and manage applications more effectively and efficiently, without being granted universal control. These specific security clearances can prevent insider attacks and interference by barring actors from moving beyond individual purview.

• High Agility and OPEX Efficiency*Breaches in data centers can remain undetected for extended periods of time. Micro-segmentation enables the data center to be far more agile and quick to react with the ability to identify the breach almost immediately and to contain it within a narrow fault domain. At the same time, its multiple layers of security help to slow the attack's spread and enable operators to lock down the hacker and secure uncompromised data at a faster rate. It's a more agile, cost-effective approach to security.

Micro-Segmentation w/ vADCImpacts of Micro-Segmentation Achieves the defined Benefits of Micro-Segmentation

– Zero Trust Security Model• No internal or external user request is trusted - every user request is validated, authenticated, and authorized using multi-factor

authentication• Utilizes explicit policy enforcement to validate and authenticate user access – every user credential/request is validated and

authenticated using multi-factor authentication for fine grain access– Application Aware Security

• Utilizes defined Policy Groups, i.e. Application Tiers, Workload Profiles, etc. to enforce authorization and access• Security is enforced at the application/virtual machine level, i.e. web application firewall for each application or virtual machine

– DevOps Alignment• Multi-factor authentication, fine grain access and web application firewalls allow application owners to control security at the

application level• Fine grain access limits user purview, restricting any movement beyond, preventing or limiting insider threats and attacks.

– High Agility and OpEx Efficiency• Software based solution for both vTM and WAF provide a highly agile and flexible solution with the ability to deploy additional (or

contract and re-deploy) the number of instances rapidly • Multi-factor authentication, fine grain access, and web application firewall provide a cost effective layered security solution for

immediate breach identification and containment

The Domain of CYBER & How to Respond to it’s Inherent Architectural Challenges

The Paradigm in the Domain of CYBER

CONFIDENTIAL 2

“In physical space, the reconnaissance is almost always easier than the

operation…in the CYBER domain, the reconnaissance is usually a more difficult

task than the follow on operation…it is tougher to penetrate a network and live on it undetected while extracting large

volumes of data from it than it is to ‘digitally speaking’ kick in the front door

and fry a circuit or two. ….An attack on a network to degrade it or destroy

information on it is generally a lesser included case of the technology and operational art needed to spy on that

same network.”

FY16 House NDAA Report

Cyber Defense Network Segmentation

The committee is aware that the Department of Defense is looking at modifying the way it builds,

maintains, and upgrades data center, including increased use of commercial cloud capabilities

and public-private partnerships. The committee is aware that as the Department increasingly

looks at software-defined networking, it could potentially reduce the mobility of cyber threats

across data center and other networks by increasing the compartmentalization and segmentation

between systems, and providing a mix of security techniques to enable access to those

compartments. Such actions have the potential to lessen the chance of a widespread or

catastrophic breach, including breaches caused by insider threats. The committee encourages

the Department to explore ways to use compartmentalization or segmentation as part of a

software-defined networking approach in order to increase the security of its networks.

The Beginning of Policy Shifts….again

Security Groups & Security Policies

Designated Consumers & Cloud Admins are able to select pre-defined security policies

already approved by the Security Admin in NSX

Security policies are applied to one or more security groups where workloads are

members

These security groups are created

on-demand by vRA at deployment time

WHAT you

want to

protect

HOW you want

to protect it

IPS – prevent DOS

attacks, enforce

Services (Firewall, antivirus, IPS etc.) and Profiles (labels representing specific policies)

Programmatic Approach to Security: An Example

NSX Security Tags can be used to define IF/THEN workflows for security services, e.g. IF
