Remote Workforce

How to Reduce Insider Threat Risks in a Hybrid Office: 10 Best Practices


The Covid-19 pandemic has changed the way we work forever. Although some part of the workforce returned to the office as soon as restrictions loosened, many employees wish to continue working remotely. According to data from Gartner, 60% of knowledge workers are remote, with at least 18% not planning to return to the office anytime soon.

A hybrid office is a great option for both types of workers. However, a hybrid work environment may pose considerable security risks for organizations and expose them to insider threats. In this article, we review ten practices to help you reduce insider threat risks in a hybrid office.

What is a hybrid office?

According to Gartner, a hybrid office is a flexible work model in which employees need to go to the office at least once a week while being permitted to work remotely the rest of the week.

The hybrid office model may differ from organization to organization. Here are the most popular variations:

Models of hybrid work

  • Flexible hybrid work model – Employees choose their location for work according to their own priorities.
  • Fixed hybrid work model – The organization sets dates and times for employees to work remotely or come to the office.
  • Office-first hybrid work model – Employees mostly work in the office but can choose to work remotely for one or two days a week.
  • Remote-first hybrid work model – Employees work remotely most of the time but visit the office occasionally.

The model you personally choose will carry some risks no matter which model that is.

Remote Employees: How to Manage Insider Risks

Why is a hybrid office environment risky for cybersecurity?

Most of the security risks of a hybrid workforce model are associated with remote workers. It’s vital to pay close attention to possible threats, as they may result in resource-exhausting cybersecurity incidents. For example, at Ubiquiti Networks an employee stole internal data using a VPN and demanded a ransom from the employer.

There are several reasons why the hybrid office model can be dangerous for your organization’s security:

Several reasons why a hybrid office is risky for IT security

  • Use of public Wi-Fi. When employees connect to your network through public Wi-Fi, there’s always a chance that a hacker may intercept the session. A malicious actor can then access all the information sent from the employee’s device to your network and may be able to use it for malicious purposes. Moreover, hackers can infect employees’ devices with malware that, in turn, can endanger your organization’s cybersecurity.
  • Insufficient device protection. Employees’ personal devices often lack tools such as antivirus software, properly configured firewalls, and encryption software. Even when an employer provides devices for remote work, employees can unintentionally expose the organization’s sensitive information to outsiders. For instance, employees can leave devices unattended at home, lose them, or have them stolen.
  • Lack of control over employees’ activity. It’s hard to watch and control remote employees’ activity. While security officers can restrict access to certain high-risk websites through firewalls within the organization, they rarely can do the same for remote workers.
  • Limited incident response capability. It’s challenging to detect and mitigate security incidents in a timely manner if many devices reside outside the organization’s security perimeter.
  • Difficulty implementing security policies. In many organizations using a hybrid model, employees often use personal devices with no security and monitoring tools installed. It’s tricky to follow an established security policy in such conditions.

A hybrid office model may seem risky for organizations from the financial and healthcare industries that work with sensitive data. However, there’s a way to improve the cybersecurity of a hybrid work setting. In the next section, we give ten best practices to help you secure your hybrid work environment against insider threats.

Top 10 Mistakes of Security Officers in Protecting Remote Workplaces

Best practices to reduce the risk of insider threats in a hybrid office environment

If your organization already uses the hybrid office model or is planning to do so, consider implementing the following security best practices to ensure a sufficient level of cybersecurity.

Best practices for insider threat protection in a hybrid office environment

1. Assess insider threat risks

Insider threat risk assessment helps you identify those data assets and areas of your organization’s network that need protection the most. When you thoroughly prioritize insider risks, it’s easier to select and implement security procedures that are likely to help you successfully prevent and deter insider threat attacks in a hybrid environment.

When performing a risk assessment, pay close attention to aspects related to hybrid and remote work. Think of how you can protect your remote workers and the devices they use for work as well as about methods to improve visibility over remote endpoints.

2. Create an insider threat program

An insider threat prevention and detection program is a set of measures an organization uses to prevent and deal with insider threats. An established insider threat program can help your organization deter, detect, and mitigate insider threats in an organized and timely manner.

Building an insider threat program [PDF] requires a whole range of activities, from estimating resources needed to implement the program to selecting employees in charge of incident detection and remediation to creating incident response strategies. Taking your organization’s specific objectives, security priorities, and resources into account is critical to make your insider threat program as effective as possible.

3. Develop a remote access policy

As a considerable share of employees work remotely in a hybrid office environment, it’s vital to establish a remote access policy (RAP). An RAP outlines the methods used for controlling access, establishing a connection with the organization’s data and systems from outside the network, protecting login credentials, and more.

A comprehensive RAP will tell your employees precisely how to safeguard their remote access to the organization’s resources. This, in turn, can reduce the risks of cybersecurity incidents coming from the hybrid office model.

4. Adopt a zero-trust architecture

Enforcing a zero-trust architecture can significantly improve your organization’s security without substantially increasing costs. In practice, zero-trust entails verifying every user before giving access to any of the organization’s resources.

This approach can help you reduce the risk of attacks on your organization’s network, increase visibility into who accesses your organization’s resources, and improve your ability to detect potential threats.

5. Implement the principle of least privilege

The principle of least privilege is yet another security approach that can help you minimize the attack surface within your hybrid environment and reinforce the security of sensitive data. When using a hybrid office model, it’s especially vital to limit users’ privileges and prevent malicious insiders or outside attackers from accessing the organization’s most valuable assets.

The principle of least privilege dictates minimizing the privileges of all your employees to only those that are necessary. That means your employees should have access only to the systems and data they require to perform their duties – nothing more, nothing less.

6. Use multi-factor authentication for all accounts and devices

Not only is multi-factor authentication (MFA) one of the best time-tested security practices; it’s also a requirement of many data privacy and security standards, laws, and regulations, such as the Payment Card Industry Data Security Standard (PCI DSS), the Sarbanes-Oxley (SOX) Act, and the Health Insurance Portability and Accountability Act (HIPAA).

MFA can help organizations using a hybrid workplace model establish a secure connection with remote workers to increase the protection of sensitive corporate data. Adopting MFA in your organization can enhance cybersecurity without hampering your employees’ productivity.

Identity Management

7. Control the use of passwords in your organization

Letting all employees know login credentials to an organization’s critical endpoints is a risk that nobody can afford. Instead, organizations can deploy password management solutions that allow employees to access certain endpoints without disclosing the actual passwords to those endpoints.

A lot of these solutions also provide manual or automated password rotation and password checkout to further protect login credentials to critical resources.

8. Monitor employee activity

Whether deliberately or carelessly, both in-office and remote employees can put your organization’s network at risk. User activity monitoring can help you increase visibility and see signs of employee negligence or malicious actions before it’s too late.

Having a robust user activity monitoring tool in your hybrid office environment can be of great help for securing hybrid teams against insider threats. Monitoring employee activity is also great for gathering evidence and comes in handy for incident investigation.

User Activity Monitoring

9. Deploy UEBA tools

Even with a monitoring solution in place, it may be hard to track when an employee’s actions start being malicious. However, deploying a user and entity behavior analytics (UEBA) solution can help your security team mitigate insider threat risks in a hybrid work environment.

When new employees start working in your network, a UEBA tool establishes their baseline behavior (i.e. normal behavior). Whenever an employee’s behavior diverges from the baseline, the UEBA tool notifies you about it so you or your security officers can look into the matter and identify if the employee’s actions are malicious.

10. Conduct cybersecurity awareness training

When employees lack cybersecurity awareness and don’t understand the organization’s security policies, they tend to overlook required security measures. According to the 2022 Cost Of Insider Threats Global Report [PDF] by the Ponemon Institute, 56% of insider incidents are caused by negligence.

By conducting regular cybersecurity training for in-office and remote employees, you can significantly reduce the number of security mistakes.
