In information security, there are many opportunities to have a lot of creative input and work with cutting-edge technology. There is also the opportunity for advancement.

This article will outline the information security roles exist, the skills required for each position, and the available career paths.

Information Security Analysts

The information security analyst is responsible for information security management, risk assessment, and response plans. They are involved in the day-to-day operations of information assurance policies, standards, guidelines, and technologies. Their responsibilities include:

  • Vulnerability assessment/penetration testing of networks, systems, and applications
  • Developing information security policies
  • Reviewing system development life cycle to ensure information assurance is addressed
  • Information risk management planning for information systems

Network Defense Engineers

Network defense engineers are information security professionals that monitor and respond to information security events. They perform analysis, reporting, and mitigation on information security risks daily. This role is critical for maintaining and protecting information assets and infrastructures from external threats.

Intrusion Detection Analysts

The intrusion detection analyst performs information risk assessment and response plans under the guidance of an information systems manager or principal information assurance officer.

In addition, they serve as subject matter experts for clients about information risk assessments and business continuity planning related to technologies such as firewalls, IDS/IPS, spam filtering, malware protection, encryption products, etc. This role requires significant knowledge of these technologies to ensure their success in detecting intrusions while preventing false positives.

Authentication Specialists/Security Token Service Providers

These infosec jobs ensure information transfers and information systems are protected from spoofing attacks by assuring the information is authenticated at all times.

For example, security token service providers offer a secure mechanism to use identification-related information, such as username and password, smart cards, certificates, etc., that have been issued to users for access control purposes.

They can also ensure that private information remains confidential through authentication mechanisms such as privacy filters on laptops or privacy screens on mobile devices where sensitive information is displayed.

Penetration Testers

A penetration tester identifies system vulnerabilities so these issues can be remediated promptly before adversaries have an opportunity to exploit them. Testers perform various vulnerability scans of operating systems, web servers, mobile devices, etc., to identify information security risks.

Once information security risks are discovered during testing, information security analysts must work with system administrators to apply patches or make other updates until the threat is remedied.

Infosec Software Developers

Software developers play a critical role in information security by designing and creating information security technologies that help information security operators protect information assets from adversaries.

As information technology has shifted to cloud services and mobile apps, information security software development has also shifted towards these platforms. It means that information security professionals working in this field require knowledge of public key infrastructures (PKIs), cryptography, app development for Android and iOS, etc.


While all information security roles can be considered cyber-crime fighters at their core, professional ethical hackers take it one step further by simulating malicious attacks against systems on behalf of clients to make sure they are protected from real threats.

Analysts gather evidence related to potential or actual cases of information security breaches to determine if a crime has been committed and by whom. Investigators are responsible for interviewing victims, examining evidence related to information security incidents, and working with law enforcement to bring perpetrators of information security crimes to justice.

In addition, researchers discover new methods or create new technologies used in information security that allow organizations to protect information from external threats.

Digital Forensics Experts

Digital forensics experts preserve information related to information security breaches and investigate information security incidents. They apply digital forensic techniques to initiate a formal investigation of information technology systems, networks, wireless communications, etc., as part of an information security plan or response plan.

Compliance Officers/Managers

Corporate information security compliance managers develop information security policies and procedures to prevent information security breaches, detect information security incidents, respond appropriately to information security incidents that occur, and restore any information or systems compromised as part of a breach.

They also oversee information technology audits for adherence to information security policies and procedures established by organizations’ governing bodies.

Relevant Career Paths

To get started in various information security jobs, individuals generally have to obtain a Bachelor’s degree in information security or information technology. After gaining their professional certification, this is followed by two years of experience working in the information security field.

After that, individuals can pursue information security certifications offered by organizations like the International Information Systems Security Certification Consortium (ISC2). The ISC2 offers information security certifications in information systems auditing and ethical hacking, information system security engineering, etc.

Individuals without information security degrees can enter information technology from several entry-level information technology positions. For example, information technology support specialists provide information security services to employees in organizations by responding to information security support requests and resolving computer issues related to information security breaches.

In addition, some IT support workers specialize in information security. Data is one of the most valuable resources today, and its protection is the primary responsibility of information security professionals. With increasing pressure on colleges and universities worldwide to demonstrate their contributions to business productivity, it’s no wonder that information security has become such an important field.
