Access Control

What is access control? A key component of data security

Access controls authenticate and authorize individuals to access the information they are allowed to see and use. Who should access your company’s data? How do you make sure those who attempt access have actually been granted that access? Under which circumstances do you deny access to a user with access privileges? To effectively protect your data, your organization’s access control policy must address these (and other) questions. What follows is a guide to the basics of access control: What it is, why it’s important, which organizations need it the most, and the challenges security professionals can face

Access control is a method of guaranteeing that users are who they say they are and that they have the appropriate access to company data. At a high level, access control is a selective restriction of access to data. It consists of two main components: authentication and authorization, says Daniel Crowley, head of research for IBM’s X-Force Red, which focuses on data security. Authentication is a technique used to verify that someone is who they claim to be. Authentication isn’t sufficient by itself to protect data, Crowley notes. What’s needed is an additional layer, authorization, which determines whether a user should be allowed to access the data or make the transaction they’re attempting. Without authentication and authorization, there is no data security, Crowley says. “In every data breach, access controls are among the first policies investigated,” notes Ted Wagner, CISO at SAP National Security Services, Inc. “Whether it be the inadvertent exposure of sensitive data improperly secured by an end user or the Equifax breach, where sensitive data was exposed through a public-facing web server operating with a software vulnerability, access controls are a key component. When not properly implemented or maintained, the result can be catastrophic.” Any organization whose employees connect to the internet—in other words, every organization today—needs some level of access control in place. “That’s especially true of businesses with employees who work out of the office and require access to the company data resources and services,”

Access control policy: Key considerations
Most security professionals understand how critical access control is to their organization. But not everyone agrees on how access control should be enforced, says Chelsea. “Access control requires the enforcement of persistent policies in a dynamic world without traditional borders,” Chelsea explains. Most of us work in hybrid environments where data moves from on-premises servers or the cloud to offices, homes, hotels, cars and coffee shops with open Wi-Fi hot spots, which can make enforcing access control difficult.

Types of access control
Organizations must determine the appropriate access control model to adopt based on the type and sensitivity of data they’re processing, says Wagner. Older access models include discretionary access control (DAC) and mandatory access control (MAC), role based access control (RBAC) is the most common model today, and the most recent model is known as attribute based access control (ABAC).

Access control solutions
A number of technologies can support the various access control models. In some cases, multiple technologies may need to work in concert to achieve the desired level of access control, Wagner says. “The reality of data spread across cloud service providers and SaaS applications and connected to the traditional network perimeter dictate the need to orchestrate a secure solution,” he notes. “There are multiple vendors providing privilege access and identity management solutions that can be integrated into a traditional Active Directory construct from Microsoft. Multifactor authentication can be a component to further enhance security.”

Why authorization remains a challenge
Today, most organizations have become adept at authentication, says Crowley, especially with the growing use of multifactor authentication and biometric-based authentication (such as facial or iris recognition). In recent years, as high-profile data breaches have resulted in the selling of stolen password credentials on the dark web, security professionals have taken the need for multi-factor authentication more seriously, he adds. Authorization is still an area in which security professionals “mess up more often,” Crowley says. It can be challenging to determine and perpetually monitor who gets access to which data resources, how they should be able to access them, and under which conditions they are granted access, for starters. But inconsistent or weak authorization protocols can create security holes that need to be identified and plugged as quickly as possible. Speaking of monitoring: However your organization chooses to implement access control, it must be constantly monitored, says Chelsea, both in terms of compliance to your corporate security policy as well as operationally, to identify any potential security holes. “You should periodically perform a governance, risk and compliance review,” he says. “You need recurring vulnerability scans against any application running your access control functions, and you should collect and monitor logs on each access for violations of the policy.” In today’s complex IT environments, access control must be regarded as “a living technology infrastructure that uses the most sophisticated tools, reflects changes in the work environment such as increased mobility, recognizes the changes in the devices we use and their inherent risks, and takes into account the growing movement toward the cloud,” Chelsea says.

Biometrics fingerprinting
Biometric recognition technology is being used increasingly more in security, and fingerprint recognition (biometric fingerprint) is currently the most commonly used biometric technology for physical access control. It makes sense – people are already used to using fingerprints to verify themselves on their Smartphone and there are many benefits to fingerprint recognition. Enrolling and presenting a fingerprint is relatively easy. And the combination of a low price point and high accuracy levels make it a good choice for many access control applications, especially those where fewer people need access.

Network Access Control
(NAC) is a computer networking solution that uses a set of protocols to define and implement a policy that describes how to secure access to network nodes by devices when they initially attempt to access the network. ... A basic form of NAC is the 802.1X standard.
