What Information Security Analysts Do About this section

information security analysts image
Information security analysts install software, such as firewalls, to protect computer networks.

Information security analysts plan and carry out security measures to protect an organization’s computer networks and systems.


Information security analysts typically do the following:

  • Monitor their organization’s networks for security breaches and investigate when one occurs
  • Use and maintain software, such as firewalls and data encryption programs, to protect sensitive information
  • Check for vulnerabilities in computer and network systems
  • Research the latest information technology (IT) security trends
  • Prepare reports that document general metrics, attempted attacks, and security breaches
  • Develop security standards and best practices for their organization
  • Recommend security enhancements to management or senior IT staff
  • Help computer users when they need to install or learn about new security products and procedures

Information security analysts are heavily involved with creating their organization’s disaster recovery plan, a procedure that IT employees follow in case of emergency. These plans allow for the continued operation of an organization’s IT department. The recovery plan includes preventive measures such as regularly copying and transferring data to an offsite location. It also involves plans to restore proper IT functioning after a disaster. Analysts continually test the steps in their recovery plans.

Information security analysts must stay up to date on IT security and on the latest methods attackers are using to infiltrate computer systems. Analysts need to research new security technology to decide what will most effectively protect their organization.

Information security analysts


Computer occupations


Total, all occupations



Employment of information security analysts is projected to grow 35 percent from 2021 to 2031, much faster than the average for all occupations.

About 19,500 openings for information security analysts are projected each year, on average, over the decade. Many of those openings are expected to result from the need to replace workers who transfer to different occupations or exit the labor force, such as to retire.


High demand is expected for information security analysts. Cyberattacks have grown in frequency, and these analysts will be needed to create innovative solutions to prevent hackers from stealing critical information or creating problems for computer networks.

As businesses focus on enhancing cybersecurity, they will need information security analysts to secure new technologies from outside threats or hacks. A shift to remote work and the rise of e-commerce have increased the need for enhanced security, contributing to the projected employment growth of these workers over the decade.

Strong growth in digital health services and telehealth will also increase data security risks for healthcare providers. More of these analysts are likely to be needed to safeguard patients' personal information and data.
