Information Security Intern Jobs in Maryland: Frequently Asked Questions
How do you become a information security intern in Maryland?
Most information security intern roles in Maryland require active enrollment in a cybersecurity, computer science, or information systems degree program at a Maryland university or community college. There is no state-issued license for interns in this field, but employers in Maryland's defense and federal contracting sectors often require candidates to be clearance-eligible, meaning U.S. citizenship and a clean background. Coursework in networking, operating systems, and security fundamentals is the most reliable foundation.
Which companies hire information security interns in Maryland?
Employers hiring information security interns in Maryland right now include Leidos, Base-2 Solutions, and Birchmere, based on current listings on Migrate Mate as of November 2026. Maryland's high concentration of defense contractors and federal agencies makes it one of the more active states for security internship programs with structured cohorts and mentorship.
Which Maryland cities have the most information security intern jobs?
The most information security intern openings in Maryland are in Annapolis Junction, Fort Meade, and Columbia. Baltimore anchors demand through its financial institutions, healthcare systems, and university research programs, while the Annapolis and Columbia corridors benefit from proximity to the National Security Agency at Fort Meade and the cluster of federal contractors that have built campuses nearby to support government security work.
Are there remote information security intern jobs in Maryland?
Yes, and more than many technical intern roles, because much of the analytical and monitoring work in information security can be done remotely. About 58% of information security intern openings tied to Maryland are remote or hybrid as of November 2026, reflecting the desk-based nature of tasks like log review and compliance documentation. Roles requiring access to classified systems or secure facilities typically remain on-site.
How can I get hired as a information security intern in Maryland with little or no experience?
The most realistic entry path is applying directly to structured internship programs at Maryland's large defense contractors, which recruit students as early as sophomore year and do not require prior professional experience. Employers like Northrop Grumman and Booz Allen Hamilton run formal intern cohorts that pair students with security analysts on live projects. Completing a CompTIA Security+ certification and building a home lab or capture-the-flag portfolio gives candidates from Maryland's community colleges and four-year universities a concrete edge over applicants with coursework alone.
Where can I find and apply to information security intern jobs in Maryland?
You can find and apply to information security intern jobs in Maryland on Migrate Mate, which lists current openings across the state. Search the available roles, find the ones that match your background and availability, and apply directly to each employer. No signup is needed to see the listings.
