Information security vs. cybersecurity

Information security is often confused with cybersecurity—which is understandable, because there is significant overlap, and many use the two interchangeably. Cybersecurity, however, refers more broadly to preventing cyberattacks that come from unauthorized electronic sources.

Information security focuses specifically on protecting the data and information of an organization, employees, or users, which can exist in both physical and electronic form. Information security also means making sure data is accessible to those who are authorized to use it.

How to become an information security analyst

If you’re interested in protecting organizations from cyber threats and keeping sensitive data safe, becoming an information security analyst could be the right career for you. It’s a role that combines technical expertise, an understanding of privacy and compliance, and the ability to work closely with teams to solve security challenges. The next sections outline a clear, step-by-step guide to help you break into this in-demand field.

Step 1: Gain essential information security analyst skills

Start by building a strong foundation in IT and cybersecurity. Learn how networks, operating systems, firewalls, and routers work, and understand the principles of risk management and data protection. Many information security analysts also develop ethical hacking or penetration testing skills to better identify and defend against potential vulnerabilities.

Beyond technical know-how, you’ll also need an understanding of data privacy laws and compliance standards, such as HIPAA for healthcare or PCI DSS for finance. Finally, strong communication and teamwork skills are crucial, as you’ll often collaborate with other teams to detect, report, and resolve security threats.

Step 2: Earn the necessary credentials

Many information security analyst roles require a bachelor’s degree in computer science, information technology, or cybersecurity. A degree provides a structured foundation in networking, programming, and system security. According to Zippia, about 62 percent of information security analysts hold a bachelor’s degree, while 20 percent have an associate degree [2].

If a degree isn’t part of your plan, you can still build a competitive resume by earning recognized cybersecurity certifications and hands-on experience. Entry-level credentials like CompTIA Security+, Network+, or Certified Ethical Hacker (CEH) are great starting points. As you advance, certifications such as CISSP or CISM can help you move into more senior or specialized cybersecurity roles.

Step 3: Get hands-on experience

Experience is key to becoming an information security analyst. Look for internships, entry-level IT roles, or cybersecurity training programs where you can apply your skills in real-world settings. Roles in network administration, technical support, or system analysis can all provide valuable experience that translates directly into information security work.
