Jobs in computer security

There are many roles in computer security worth pursuing. These include: 

  • Information security specialist: These experts often define organizational guidelines for systems and processes that keep private information safe. They advise and train others on areas of vulnerability and ways to mitigate cybersecurity threats.1

  • Information systems security officer: When security issues occur, these experts will play a key role in responding, reporting, investigating, and solving vulnerabilities.2

  • Cybersecurity specialist: Like the positions above, these specialists play an important function in maintaining the networks and data of organizations. But they also anticipate and prepare for future threats.3

  • Penetration tester: Those in this role are legally and ethically allowed to test networks and applications to identify vulnerabilities. They will also do physical assessments, conduct security audits, analyze security policies, and collate reports.4

  • Network security analyst: These analysts are in charge of preventing data loss and service interruptions by installing security measures like firewalls and data encryption. They also need to stay abreast of emerging threats, hacker methodologies and new forms of protection.5

  • Systems analyst: These are IT professionals who ensure that systems, infrastructures, and computer systems are functioning as efficiently as possible. They study current systems, procedures and business processes to create action plans for the organization’s requirements.6

  • Computer security analyst: Also known as information systems security analysts. Security analysts are responsible for ensuring that an organization’s online and on-premises infrastructures are secure. They look through data to filter out suspicious activity and mitigate risks. When breaches happen, security analysts may lead counter efforts to the attacks.7

How to become a computer security analyst online

Requirements vary for computer or information security analysts based on the employer, your particular role, and your background experience. So your career path may not be clear cut. 

Most professionals working as information security analysts hold a bachelor’s degree.8 This may be a bachelor’s degree in computer or data science or a related field. Some professionals in more senior roles may hold a master’s degree.

Employers may also prefer to hire analysts who have professional certification. A large portion of people working in computer security say a post-baccalaureate certificate is required for their job.9 Some of these certifications, such as CompTIA Security+, are for entry-level workers, while others, such as the Certified Information Systems Security Professional (CISSP), are geared toward experienced information security workers. You can also pursue certification in specialized areas, such as systems auditing.10

Many computer security analysts have work experience in a related field, such as information technology, in positions such as as a network and computer systems administrator. 

Assess your experience and goals and determine the gaps in your skill set. Then you can research whether a computer security course, professional certificate program, or another option is your best choice. Online cybersecurity boot camps teach you technical skills in as few as 24 weeks. Learn cybersecurity from curriculums that cover Windows and Linux administration techniques, risk management, penetration testing, cloud security, Metasploit, Hashcat, and more.
