Identity and Access Management is an important part of today’s evolving world. It is the process of managing who has access to what information over time. Activity of IAM involves creation of identities for user and system. Secure user access plays a key role in the exchange of data and information. In addition, electronic data is becoming ever more valuable for most companies. Access protection must therefore meet increasingly strict requirements – an issue that is often solved by introducing strong authentication. Identity and the Access are two very important concept of the IAM which are needed to be managed by the company. Companies are now relying more on the automated tool which can manage all these things. But then it creates the risk. Because tools are not intelligent enough to take the decisions, so we can add the intelligence by using the various data mining algorithm. This can keep the data over time and then build the models. This article covers the key challenges associated with Identity and Access Management
1. IAM as a critical foundation for realizing the business benefits
Currently, companies are more and more concerned in complex value chains also they necessary to both integrate and offer a range of information systems. As a result of this, the lines among service providers and users and among competitors are blurring. Companies therefore need to implement efficient and flexible business processes focused on the electronic exchange of data and information. Such processes require reliable identity and access management solutions. IAM is the process which manages who has access to what information over time. Activity of IAM involves creation of identities for user and system. Identity and Access Management IAM has recently emerged as a critical foundation for realizing the business benefits in terms of cost savings, management control, operational efficiency, and, most importantly, business growth for ecommerce. Enterprises need to manage access to information and applications scattered across internal and external application systems. Moreover, they must provide this access for a growing number of identities, both inside and outside the organization, without compromising security or exposing sensitive information.
IAM comprises of people, processes and products to manage identities and access to resources of an enterprise. An identity access management (IAM) system is a framework for business processes that facilitates the management of electronic identities. Poorly controlled IAM processes may lead to regulatory non-compliance, because if the organization is audited, management will not be able to prove that company data is not at risk for being misused.
Additionally, the enterprise shall have to ensure the correctness of data in order for the IAM Framework to function properly. IAM components can be classified into four major categories: authentication, authorization, user management and central user repository (Enterprise Directory). The ultimate goal of IAM Framework is to provide the right people with the right access at the right time.
2. Key Concept of IAM
Secure user access plays a key role in the exchange of data and information. In addition, electronic data is becoming ever more valuable for most companies. Access protection must therefore meet increasingly strict requirements – an issue that is often solved by introducing strong authentication. Modern IAM solutions allow administering users and their access rights flexibly and effectively, enabling multiple ways of cooperation. Also, IAM is a prerequisite for the use of cloud services, as such services may involve outsourcing of data, which in turn means that data handling and access has to be clearly defined and monitored.
- Identity The element or combination of element that uniquely describes a person or machines is called Identity. It can be what you know such as password or other personal information what you have or any combination of these.
- Access The information representing the rights that identity was granted. This information the access rights can be granted to allow users to perform transactional functions at various levels. Some examples of transactional functions are copy, transfer, add, change, delete, review, approve and cancel.
- Entitlements The collection of access rights to perform transactional functions is called entitlements. The term entitlements are used occasionally with access rights. Identity and access management is the, who, what, where, when, and why of information technology. It encompasses many technologies and security practices, including secure single sign-on (SSO), user provisioning/de provisioning, authentication, and authorization.
Over the past several years, the Fortune 2000 and governments worldwide have come to rely on a sound IAM platform as the foundation for their GRC strategies. As more organizations decentralize with branch and home offices, remote employees, and the consumerization of IT, the need for strong security and GRC practices is greater than ever
3. Function of Identity Management
The identity management system stores information on all aspects of the identity management infrastructure. Using this information, it provides authorization, authentication, user registration and enrolment, password management, auditing, user self-service, central administration, and delegated administration.
• Stores information The identity management system stores information about the following resources: applications (e.g. business applications, Web applications, desktop applications), databases (e.g. Oracle, DB2, MS SQL Server), devices (e.g. mobile phones, pagers, card keys), facilities (e.g. warehouses, office buildings, conference rooms), groups (e.g. departments, workgroups), operating systems (e.g. Windows, Unix, MVS), people (e.g. employees, contractors, customers), policy (e.g. security policy, access control policy), and roles (e.g. titles, responsibilities, job functions).
• Authentication and authorization
The identity management system authenticates and authorizes both internal and external users. When a user initiates a request for access to a resource, the identity management first authenticates the user by asking for credentials, which may be in the form of a username and password, digital certificate, smart card, or biometric data. After the user successfully authenticates, the identity management system authorizes the appropriate amount of access based on the user’s identity and attributes. The access control component will manage subsequent authentication and authorization requests for the user, which will reduce the number of passwords the user will have to remember and reduce the number of times a user will have to perform a logon function. This is referred to as “single sign-on”.
• External user registration and enrolment The identity management system allows external users to register accounts with the identity management system and also to enrol for access privileges to a particular resource. If the user cannot authenticate with the identity management system the user will be provided the opportunity to register an account. Once an account is created and the user successfully authenticates, the user must enrol for access privileges to requested resources. The enrolment process may be automated based on set policies or the owner of the resource may manually approve the enrolment. Only after the user has successfully registered with the identity management system and enrolled for access will access to that resource be granted.
• Internal user enrolment The identity management system allows internal users to enroll for access privileges. Unlike external users, internal users will not be given the option to register because internal users already have an identity within the identity management system. The enrolment process for internal users is identical to that of external users.
• Auditing The identity management system facilitates auditing of user and privilege information. The identity management system can be queried to verify the level of user privilege. The identity management system provides data from authoritative sources, providing auditors with accurate information about users and their privileges.
• Central administration The identity management system allows administrators to centrally manage multiple identities. Administrators can centrally manage both the content within the identity management system and the structural architecture of the identity management system.
4. Challenges in IAM
Today’s enterprise IT departments face the increasingly complex challenge of providing granular access to information resources, using contextual information about users and requests, while successfully restricting unauthorized access to sensitive corporate data.
With the growth of cloud-based and Software as a Service (SaaS) applications, users now have the power to log in to critical business apps like Salesforce, Office365, Concur, and more anytime, from any place, using any device. However, with the increase of distributed applications comes an increase in the complexity of managing user identities for those applications. Without a seamless way to access these applications, users struggle with password management while IT is faced with rising support costs from frustrated users. Solution is a holistic IAM solution can help administrators consolidate, control, and simplify access privileges, whether the critical applications are hosted in traditional data centers, private clouds, public clouds, or a hybrid combination of all these spaces.
Without a centralized IAM system, IT staff must provision access manually. The longer it takes for a user to gain access to crucial business applications, the less productive that user will be. On the flip side, failing to revoke the access rights of employees who have left the organization or transferred to different departments can have serious security consequences. To close this window of exposure and risk, IT staff must de-provision access to corporate data as quickly as possible. Manual provisioning and de provisioning of access is often supposed to cause human error or oversights. Especially for large organizations, it is not an efficient or sustainable way to manage user identities and access. Solution is a robust IAM solution that can fully automate the provisioning and de-provisioning process, giving IT full power over the access rights of employees, partners, contractors, vendors, and guests. Automated provisioning and de provisioning speed the enforcement of strong security policies while helping to eliminate human error.
- Bring your own device (BYOD)
The challenge with BYOD is not whether outside devices are brought into the enterprise network, but whether IT can react quickly enough to protect the organization’s business assets—without disrupting employee productivity and while offering freedom of choice. Nearly every company has some sort of BYOD policy that allows users to access secure resources from their own devices. However, accessing internal and SaaS applications on a mobile device can be more cumbersome than doing so from a networked laptop or desktop workstation. In addition, IT staff may struggle to manage who has access privileges to corporate data and which devices they’re using to access it. Solution is enterprises must develop a strategy that makes it quick, easy, and secure to grant—and revoke—access to corporate applications on employee- and corporate-owned mobile devices based on corporate guidelines or regulatory compliance.
Compliance and corporate governance concerns continue to be major drivers of IAM spending. Ensuring support for processes such as determining access privileges for specific employees, tracking management approvals for expanded access, and documenting who has accessed what data and when they did it can go a long way to easing the burden of regulatory compliance and ensuring a smooth audit process. Solution is a strong IAM solution can support compliance with regulatory standards such as HIPAA. In particular, a solution that automates audit reporting can simplify the processes for regulatory conformance and can also help generate the comprehensive reports needed to prove that compliance.
Efficiency, Security and Compliance are important keys of Identity and Access Management. Benefits of deploy a vigorous IAM solution are clear, the complexity and cost of implementation can disrupt even the most well-intentioned organization. A robust IAM solution can ease organization pains, streamline provisioning and de-provisioning, and improve user productivity, while lowering costs, dropping demands on IT, and providing the enterprise with comprehensive data to assist in complying with regulatory standards.
