With more people conducting business online and via cloud and SaaS applications than ever before, cybersecurity is top of mind for every organization. Any sort of digital breach can result in significant financial and data loss. To combat these growing threats, businesses are commonly adopting identity and access management (IAM) tools.
IAM is a comprehensive framework encompassing the technologies, policies, and procedures that ensure only approved individuals or systems gain access to certain digital resources. IAM establishes the roles and privileges of network users, acting as a complex security checkpoint that determines what applications users can access and what operations they’re allowed to perform.
Robust IAM procedures are critical for cybersecurity, and are often mandated by regulations such as the General Data Protection Regulation (GDPR) in Europe and the Health Insurance Portability and Accountability Act (HIPAA) in the United States.
Meanwhile, “SaaS management” is inextricably linked with IAM. Properly-implemented IAM systems offer granular control over users and their interactions within SaaS platforms. This is vital for defining roles within the system. For instance, while a regular employee may only have access to data necessary for their role, a system administrator might have broad access to most or all of the system.
Developing and managing such solutions in-house can be challenging, and not all companies have the expertise to do so. Many SaaS security solutions provide cloud-based IAM services to clients, making it easier for businesses to implement effective IAM frameworks.
IAM isn’t static—it constantly evolves to adapt to new security threats. For that reason, many IAM systems today include AI-based algorithms that detect anomalous behavior, even if the correct credentials have been used for login. IAM solutions also have to be scalable. They need to be able to accommodate a growing number of users without compromising security or performance. Achieving this level of scalability often involves the use of cloud-based IAM solutions, which allow users to grow or scale down as needed.
Cybersecurity includes everything from traditional IT infrastructure to cloud services. The role of identity and access management in cybersecurity has become especially important in managing this brand scope. With businesses increasingly migrating to the cloud, the importance of robust IAM systems in safeguarding digital architectures cannot be overstated.
But what is access management in cybersecurity? It’s a complex process that deals specifically with managing permissions and capabilities once users are authenticated. It involves the use of policies and protocols to restrict what users can see and do, generally operating on the principle of least privilege: that users should only have access to the minimum levels of access necessary to perform their jobs.
One example of IAM in cybersecurity is multi-factor authentication (MFA). This requires users to provide two or more verification factors to gain access to an account. This layered approach makes it significantly more difficult for unauthorized users to gain access.
Other examples include role-based access control (RBAC), where users are only allowed access to information pertinent to their role within the organization, or single sign-on (SSO) services, which allow users to access multiple services with a single set of credentials, but can be a vulnerability if not properly secured.
Identity and access management becomes even trickier once you layer in SaaS. Because each app comes with its own quirks, permissions, and admin models, even more roadblocks need to be overcome.
Here are the key challenges:
Each of these challenges can multiply and take bigger pieces of your security posture and your budget. If they’re not addressed, they create a complicated environment where attackers thrive and compliance becomes a moving target.
Despite the challenges, there’s good news. With proven strategies and best practices, organizations can manage IAM complexity in their SaaS-heavy environments.
Here’s what works best today:
Strong SaaS IAM transcends security and creates waves of operational efficiency throughout the organization. When employees can log in easily, managers don’t waste time approving access, and IT teams aren’t buried in manual tickets, the entire organization wins.
There are several things to consider when choosing between IAM solutions. To ensure they find the most appropriate solutions for their particular needs, businesses should outline their goals and objectives. They should also carefully consider scalability and the extent to which they’re likely to grow—or downsize—in the short and long term.
The best identity and access management tools prioritize scalability. Look for a platform that’s capable of growing alongside your business without requiring frequent changes or upgrades. Identity and access management solutions that offer a great deal of scalability tend to be more cost-effective and future-proof than those that do not.
Another key feature is flexibility. Each organization has unique needs, and good IAM tools tailor security protocols and access permissions based on those specific requirements. Customization allows businesses to implement security measures that are directly aligned with their operational needs without imposing unnecessary restrictions or vulnerabilities.
User experience is also crucial. Poorly-designed IAM systems can frustrate users and lead to workarounds that compromise security. Businesses should thus opt for identity management software that provides an intuitive and straightforward user interface. Importantly, the solution should allow for SSO and easy MFA.
Real-time monitoring and auditing capabilities are also essential. Businesses must be able to track who accessed what information, when, and from where. Effective access management solutions provide robust reporting tools that make it easier for security teams to monitor access patterns, spot irregularities, and take quick corrective actions when necessary.
When selecting an IAM solution, consider its interoperability with other systems. This is particularly important for businesses that use a mix of on-premises and cloud-based solutions. The IAM platform should offer seamless integration capabilities with a variety of other software and systems.
Automation capabilities should also be evaluated. Automation in IAM solutions can range from automated de-provisioning of user accounts when an employee leaves the organization to automated reports that are generated and sent to compliance officers. The more automated the system, the less manual work is required, reducing the likelihood of human error. Ultimately, while there isn’t a single one-size-fits-all solution when it comes to IAM, it’s important to look for a holistic feature set that’s designed to tackle today’s cybersecurity challenges.
