The document discusses identity and access management (IAM). IAM is a framework that facilitates managing electronic identities and controlling user access to information. It encompasses identifying individuals, roles, access levels, and protecting sensitive data. Authentication verifies users' identities through factors like passwords, biometrics, or tokens. Authorization controls access through roles or policies based on attributes. IAM tools automate provisioning and access management. Implementing effective IAM brings security, compliance and efficiency benefits.

Management

2. Identity and access management architecture
Identity and access management (IAM) is a framework of business processes,
policies and technologies that facilitates the management of electronic or digital
identities.
By IAM, information technology (IT) managers can control user access to critical
information within their organizations.
IAM systems can be deployed on premises, provided by a third-party vendor
through a cloud-based subscription model or deployed in a hybrid model.

3. Components of IAM
On a fundamental level, IAM encompasses the following components:
● How individuals are identified in a system (understand the difference
between identity management and authentication);
● How roles are identified in a system and how they are assigned to individuals;
● Adding, removing and updating individuals and their roles in a system;
● Assigning levels of access to individuals or groups of individuals; and
● Protecting the sensitive data within the system and securing the system
itself.

4. Authentication and Authorization
Any combination of the following 3 factors
will be considered as Strong Authentication:
● What you know
○ Password
○ Passphrase
● What you are
○ Iris
○ Fingerprint
● What you have
○ Token
○ Smartcard
2 primary forms of Authorization:
● Coarse-Grain
○ High-level and overarching
entitlements
○ Create, Read, Update, Modify
● Fine-Grain
○ Detailed and explicit entitlements
○ Based on factors such as time, dept,
role and location

5. Types of 2FA

6. Types of digital authentication
❖ Unique passwords: The most common type of digital authentication is the
unique password. To make passwords more secure, some organizations
require longer or complex passwords that require a combination of letters,
symbols and numbers.
❖ Pre-shared key (PSK): PSK is another type of digital authentication where
the password is shared among users authorized to access the same resources
-- think of a branch office Wi-Fi password. This type of authentication is less
secure than individual passwords.

7. Types of digital authentication
❖ Behavioral authentication: When dealing with highly sensitive information
and systems, organizations can use behavioral authentication to get far more
granular and analyze keystroke dynamics or mouse-use characteristics. By
applying artificial intelligence, a trend in IAM systems, organizations can
quickly recognize if user or machine behavior falls outside of the norm and
can automatically lock down systems.
❖ Biometrics: Modern IAM systems use biometrics for more precise
authentication. For instance, they collect a range of biometric characteristics,
including fingerprints, irises, faces, palms, gaits, voices and, in some cases,
DNA. Biometrics and behavior-based analytics have been found to be more
effective than passwords.

8. Authorization
The oldest approach to Authorization, Access Control Lists (ACLs) set access to
resources per user (e.g., “Janet can access these applications; Steve can access
those”) rather than by user type.
Role-Based Access Control (RBAC) appeared to solve this problem. By creating
user roles and then assigning one or more roles to each user, RBAC became the
standard Authorization solution in the 1990s, and is still used in many
corporations. it can be too rigid: if a worker legitimately needs temporary access to
resources that are “outside” their given role, coarse-grained RBAC has no simple
way to allow it, thus obstructing legitimate business needs

9. Authorization
Fine-grained Authorization emerged, namely Attribute-Based Access Control
(ABAC) and Policy-Based Access Control (PBAC).
First, they all permit multiple criteria, such as department, job code, time of day,
project status, server status, certification status, risk score, IP address, or even user
location to be used as input for Authorization decisions. Using varied criteria for
Authorization increases the security of the IAM solution because it allows greater
control of the circumstances under which permissions are granted. At the same
time, a specific fine-grained policy may authorize a cross-company team to access
resources normally outside of their usual responsibilities.

10. Identity and Access Management tools

11. IAM technologies and tools
● IAM technologies are designed to simplify the user provisioning and account
setup process.
● These systems should reduce the time it takes to complete these processes
with a controlled workflow that decreases errors and the potential for abuse
while allowing automated account fulfillment.
● An IAM system should also allow administrators to instantly view and change
evolving access roles and rights.
● IAM systems should be used to provide flexibility to establish groups with
specific privileges for specific roles so that access rights based on employee
job functions can be uniformly assigned.

12. Benefits of IAM
● Access privileges are granted according to policy, and all individuals and
services are properly authenticated, authorized and audited.
● Companies that properly manage identities have greater control of user
access, which reduces the risk of internal and external data breaches.
● Automating IAM systems allows businesses to operate more efficiently by
decreasing the effort, time and money that would be required to manually
manage access to their networks.
● In terms of security, the use of an IAM framework can make it easier to
enforce policies around user authentication, validation and privileges, and
address issues regarding privilege creep.
● IAM systems help companies better comply with government regulations by
allowing them to show corporate information is not being misused.
Companies can also demonstrate that any data needed for auditing can be
made available on demand.

13. IAM solutions approach
Businesses need to identify who within the organization will play a lead role in
developing, enacting and enforcing identity and access policies.
IAM impacts every department and every type of user (employee, contractor,
partner, supplier, customer, etc.), so it's essential the IAM team comprises a mix of
corporate functions.
Organisation needs to follow the right approach to implement IAM. Let’s discuss
that in few next slides.

14. Steps for building an effective IAM architecture
❖ Make a list of usage, including applications, services, components and other
elements users will interact with. This list will help validate that usage
assumptions are correct and will be instrumental in selecting the features
needed from an IAM product or service.
❖ Understand how the organization's environments, such as cloud-based
applications and on-premises applications, link together. These systems
might need a specific type of federation (Security Assertion Markup
Language OpenID Connect, for instance).

15. Steps for building an effective IAM architecture
❖ Know the specific areas of IAM most important to the business. Answering
the following questions will help:
➢ Is multifactor authentication needed?
➢ Do customers and employees need to be supported in the same system?
➢ Are automated provisioning and deprovisioning required?
➢ What standards need to be supported?
Implementations should maintain documentation for better expectations and
responsibilities for IAM success. Businesses also should make sure to centralize
security and critical systems around identity. Perhaps most important,
organizations should create a process they can use to evaluate the efficacy of
current IAM controls.

16. IAM risks
❖ Collecting and keeping only important data for Biometric is important.
Organizations should know what biometric data they have, what they need,
how to get rid of what they don't require, and how and where data is stored.
❖ Cloud-based IAM can be of concern when the provisioning and
deprovisioning of user accounts aren't handled correctly, if there are too
many vulnerable inactive assigned user accounts, and if there is a sprawl in
admin accounts. Organizations need to ensure lifecycle control over all
aspects of cloud-based IAM to prevent malicious actors from gaining access
to user identities and passwords.

17. Future of IAM Implementations
The move to the cloud, the adoption of microservices architectures, the
digitalization of the modern world and the resulting growth in cyber-threats
continue to expand the use cases for IAM.
“To meet these new challenges, IT leaders must evolve their IAM systems,” says Mary
Ruddy, research vice president at Gartner.
Here are four ways to evolve that
● Integrate more closely with security and fraud systems.
● Support higher levels of automation and communication between IAM
modules.
● Incorporate a development security operations (DevSecOps) approach.
● Implement customer data management policies that are more respectful of
customer consent and preferences.

18. Ways to improve IAM
Integrate more closely with security and
fraud systems. Compromised identity
credentials continue to be a major element
in data breaches. The number of these
breaches, including identity-related fraud
(such as account takeovers), is growing.
Support higher levels of automation and
communication between IAM modules. This
includes access management, identity
governance and administration, and
privileged access management.
Incorporate a development security
operations (DevSecOps) approach. This
requires a change in organizational mindset,
and is especially important for organizations
developing their own applications and
services.
Implement customer data management
policies that are more respectful of
customer consent and preferences. This is
necessary to meet new and expanding
privacy regulations and evolving customer
expectations.

19. Decentralized identity
The number of identities for people, things, services and robotic process
automation bots keep growing and the walls between identity domains are
blurring IAM architecture.
Blockchain-enabled identities and decentralized identity are forcing IAM systems
to allow users to create, prove (via trusted third parties), and register their own
identity and related relationship identifiers to utilize digital services. For
organizations, this will reduce their costs and operational risks by eliminating the
need for replicated identity repositories and data

20. Next-generation adaptive access services
One of the most pronounced trends in IAM today is the use of analytics.
“Whereas traditional adaptive authentication was rule-based, the next generation of
adaptive access services combines rules with machine learning and advanced analytics,
Rules are useful but limiting. You may not have thought of all possible scenarios.” says
Paul Rabinovich, senior director at Gartner.
For example, unsupervised learning is good at anomaly detection. An organization
can establish a baseline for a user or a group of “similar” users, and it can detect
that today the user is behaving differently and take corrective action.

21. Privileged access management (PAM)
“PAM is all about securing the keys to your kingdom, it is one of the most critical security
controls to implement.” says Gartner senior director Felix Gaehtgens.
Data breaches resulting from privileged account compromise are a top concern
with IAM in the cloud. Privileged access management (PAM) solutions, including
PAM analytics that monitor for high-risk situations, are available to combat this
concern. PAM solutions are required for platform as a service (PaaS) and
infrastructure as a service (IaaS), which are on the rise as organizations build agile,
intelligent IAM platforms.
