Sobering statistics

$3.5MThe average cost of a data breach to a company

243The average number of days that attackers reside within a victim’s network before detection

76%of all network intrusions are due to compromised user credentials

$500BThe total potential cost of cybercrime to the global economy

Changing nature of cyber-security attacks

5

Costing significant financial loss, impact to

brand reputation, loss of confidential data,

and executive jobs

Compromising user credentials in the vast

majority of attacks

Using legitimate IT tools rather than malware

– harder to detect

Staying in the network an average of eight

months before detection

The problem

9

Traditional IT security tools are typically:

Designed to protect

the perimeter

Complex Prone to false

positives

When user credentials are

stolen and attackers are in the

network, your current

defenses provide limited

protection.

Initial setup, fine-tuning,

creating rules and

thresholds/baselines can

take a long time.

You receive too many reports

in a day with several false

positives that require valuable

time you don’t have.

The ATA

• History• 2010 – Aorato company was founded.

• Nov 2014 – Microsoft buys Aorato.

• Aorato‘s employees continue to work under MS label

• Aug 2015 – Microsoft ATA released.

• ATA = Advanced Threat Analytics• Powerfull security tool.

• Continuous development of new detection routines.

• „Easy“ to deploy.

• „Easy“ to configure.

Introducing MS Advanced Threat Analytics

11

An on-premises platform to identify advanced security attacks before they cause damage

Credit card companies

monitor cardholders’

behavior.

If there is any abnormal

activity, they will notify the

cardholder to verify charge.

Microsoft Advanced Threat Analytics brings this

concept to IT and users of a particular organizationComparison:

Advanced Threat Analytics Benefits

13

Detect threats fast with Behavioral Analytics

Adapt as fast as your enemies

Focus on what is important fast using the simple attack timeline

Reduce the fatigue of false positives

Prioritize and plan for next steps

No need for creating rules,

fine-tuning or monitoring a

flood of security reports, the

intelligence needed is ready to

analyze and self-learning.

ATA continuously learns from

the organizational entity

behavior (users, devices, and

resources) and adjusts itself to

reflect the changes in your

rapidly-evolving enterprise.

The attack timeline is a clear,

efficient, and convenient feed

that surfaces the right things

on a timeline, giving you the

power of perspective on the

“who-what-when-and how” of

your enterprise.

Alerts only happen once

suspicious activities are

contextually aggregated, not

only comparing the entity’s

behavior to its own behavior,

but also to the profiles of

other entities in its interaction

path.

For each suspicious activity or

known attack identified, ATA

provides recommendations for

the investigation and

remediation.

Why Microsoft Advanced Threat Analytics?

14

AdaptabilitySpeed Simplicity Accuracy

Key features

15

Witnesses all authentication and

authorization to the

organizational resources within

the corporate perimeter or on

mobile devices

Mobility support Integration to SIEM Seamless deployment

Works seamlessly with SIEM

Provides options to forward

security alerts to your SIEM or to

send emails to specific people

Functions as an appliance hardware

or virtual

Utilizes port mirroring to allow

seamless deployment alongside AD

Does not affect existing

network topology

How MS Advanced Threat Analytics works

16

Analyze1 After installation:

• Simple non-intrusive port mirroring

configuration copies all AD-related traffic

• Remains invisible to the attackers

• Analyzes all Active Directory traffic

• Collects relevant events from SIEM and

other sources


ATA:

• Automatically starts learning and profiling

entity behavior

• Identifies normal behavior for entities

• Learns continuously to update the activities

of the users, devices, and resources

Learn2

What is entity?

Entity represents users, devices, or resources


Detect3 Microsoft Advanced Threat Analytics:

• Looks for abnormal behavior and identifies

suspicious activities

• Only raises red flags if abnormal activities are

contextually aggregated

• Leverages world-class security research to

detect known attacks and security issues

(regional or global)

ATA not only compares the entity’s behavior to its own, but also to the behavior of entities in its interaction path.


Alert4

ATA reports all suspicious

activities on a simple,

functional, actionable

attack timeline

ATA identifies

Who?

What?

When?

How?

For each suspicious

activity, ATA provides

recommendations for

the investigation and

remediation.

Topology

21

Topology - Gateway

22

Captures and analyzes DC network

traffic via port mirroring

Listens to multiple DCs from multiple

domains on a single Gateway

Receives events from SIEM

Retrieves data about entities from the

domain

Performs resolution of network entities

Transfers relevant data to the ATA

Center

Topology - Center

23

Manages ATA Gateway configuration

settings

Receives data from ATA Gateways and

stores in the database

Detects suspicious activity and

abnormal behavior (machine learning)

Provides Web Management Interface

Supports multiple Gateways

Rizika nasazení • Může si vyžádat pokročilejší konfiguraci aktivních síťových prvků (switchů)

• Může si vyžádat instalaci několika ATA Gateways (a tedy licencí Windows Server Standard nebo vyšších + HW kapacit)

• Výběr vhodného umístění v síti

• HW nároky

• Potřebný počet ATA Gateways – problematické zejména u klastrových prostředí (Hyper-V, VMWare, apod.)
