Information Security Systems for Businesses

Recent data breaches at major companies have brought INFOSEC some popularity. But it’s a risk that’s increased for decades in information security system.

Any business that stores personal information about their customers worries about potential hacks. These leaks could put them at risk of a public relations nightmare.

Companies also lose potential income and intellectual property if malicious software damages their network. Digital threats continue to evolve and improve security breaches. That means businesses need dedicated information systems security experts to protect them from a security breach or threat.

And more demand means a great job outlook.

Job Outlook for Computer Information Security

The demand for INFOSEC specialists has increased over the last few decades. And the widespread use of smartphones has accelerated it further.

The Bureau of Labor Statistics (BLS) predicts a 35 percent employment growth from 2021 to 2031. This is much faster than the average for all occupations. The BLS also expects 19,500 openings for information systems security analysts each year.

As of 2021, most information systems security analysts worked in one of two industries within the INFOSEC career:

  • Professional, scientific, and technological systems services: 42.4% of digital security analysts
  • Finance and insurance: 15.1% of digital security analysts

According to the BLS, 0.2% of analysts were self-employed. The other 99.8% fall under total wage and salary employment.
