Mitigating Insider Threats to Bring Peace of Mind

Today’s most damaging security threats are not originating from external hackers or malware but from trusted insiders—both malicious and negligent.

The Cybersecurity Insiders online community, in partnership with the LinkedIn Information Security Community, conducted an in-depth study of insider threat. The resulting report is the most comprehensive research on this topic to date, revealing how IT and security professionals are dealing with risky insiders and how organizations are preparing to better protect their critical apps, data and IT infrastructure.

What is insider threat?

An insider threat is a threat that originates from an individual within the organization—an employee, contractor or business partner. This threat could be intentional—the malicious insider who wants to steal data for profit or wreak havoc for personal reasons. The threat could also be accidental—a user mistakenly deleting data or causing harm to IT systems. The accidental insider could also have their credentials compromised, thereby giving access to network resources to an external actor.

Combating Insider Threat with CA Technologies

Businesses today must reduce the risk of security breaches to protect valuable data within their organizations by addressing external actors and insider threats. At the same time, IT auditors and regulators are increasingly enforcing ever more stringent requirements on the business.

The Cybersecurity Insiders survey found that financial and customer data were the most vulnerable (57%), but privileged account information was the second most vulnerable data (52%). Unfortunately, these two are inter-related because stealing the second can lead to stealing the first.

The right privileged access management solution enhances legacy network security and stops attackers by preventing unauthorized access to privileged accounts. In addition, the right vendor can also provide several complementary solutions to further combat insider threat including multi-factor authenticationsingle sign-on and identity and access management.

Machine Learning and User Behavior Analytics

Compromised privileged accounts are the most common source of security breaches today. Once attackers gain access to a legitimate user identity, they can access all the data and systems to which the identity has access. Often, these attacks can go unnoticed for weeks, or even months, while the perpetrator is traversing the network.

As organizations are faced with rapidly growing sets of privileged identities that have access to sensitive and large datasets, the traditional approach of controlling access simply will not scale and does not address insider threat. Organizations need to move to an automated mechanism for gaining visibility and assessing risk; threat analytics is the strategic solution that addresses these challenges.

Privileged Access Management for Mainframe

Privileged access management is not unique to the distributed world—70% of corporate data still transacts on the mainframe and more than 2.5 billion transactions are processed daily on mainframe environments worldwide. Securing this data and protecting access to it is critical for many organizations—not just to guard against insider threat and targeted breaches, but to address internal privacy policies and external data privacy regulations such as GDPR.

Privileged identities on the mainframe have access to the most sensitive resources in your data center. When these are not managed properly, the business is exposed to significant risk of data loss. CA Trusted Access Manager for Z provides streamlined and secure management of these identities, helping to mitigate these security risks. By eliminating the need for shared credentials, working with existing tools and producing forensics on all privileged user activity, CA Trusted Access Manager for Z helps you stay in complete control over mission-essential mainframe data.

Privileged Identity Governance

Privileged access management and privileged password vault solutions have been deployed in many organizations in an attempt to combat insider threats and targeted breaches. However, despite these precautions, data loss is on the rise. As a result, new government regulations and industry guidelines are mandating that additional controls be placed on privileged access.

A written set of policies sitting on a shelf are no longer sufficient. Companies must now show that they are constantly monitoring how users are granted access to privileged accounts and sensitive data and that they are periodically certifying that these access entitlements are still needed. For this reason, many organizations are looking to improve their risk management posture by integrating their privileged access management and identity management technologies to achieve privileged identity governance.

Multi-factor Authentication

In the real world, communication is an illusion. People talk, but they are not often heard or understood. In the digital world, we face a different type of illusion. Dialogue occurs between users and systems, or nothing else happens. The single biggest problem in digital communication is not that it has taken place, but rather that it has taken place with the right person.

Consider the most common digital communication today—authentication. Users request access and are then challenged to present login credentials. This digital dialogue occurs millions and millions of times every minute of every day around the globe and it is built on one very simple principle—trust. The application is trusting that the legitimate owner is submitting these credentials. But this trust is easily compromised, as passwords can be easily stolen, guessed or given away.
