Here are six issues that employers need to consider, according to Marsh's 2016 Terrorism Risk Insurance Report:

1. Crisis management

Companies should develop and test an overall framework for management, response and recovery.

After an attack, organizations need to move quickly and efficiently to understand the potential effects on people, property and operations, and make policy and strategy decisions to address and manage those effects.

2. Crisis communications

Your company may have to contact employees, customers, investors and others.

During a crisis, messages and communications should be linked to reinforce the overall strategies and decisions made by the crisis management team.

In addition, consider setting up a company Facebook page or group and encouraging all employees to use Facebook's Safety Check as appropriate to let employers, coworkers, family and friends know they're safe.

3. Emergency response

Responding to physical incidents could involve the following:

•          The safety of lives, including employees, customers, vendors or family members.
•          Mitigating the effect of the event itself.
•          Evacuations of employees and their family members.
•          The protection of physical assets, for example, from looters or vandals.

4. Humanitarian assistance

Providing support to your employees during and after an incident could include physical, social, emotional and financial help, as needed.

One example of the way companies can support their employees is by making professional counseling and support services readily available.

5. Business continuity

After you've dealt with the safety issues, your next priority is keeping your business running.

Your company's strategic plan should account for the management and logistics of continuing or resuming operations, as well as recovering partially or completely interrupted critical business functions.

6. Information technology and disaster recovery

In 2016, most business processes are driven by technology to a certain degree. Recovery should include plans to ensure the availability of networks, applications and data.

When you ensure that your technology is up and running efficiently, you'll support business continuity, including working remotely and other strategies.
