  • Teamwork: A collaborative attitude with strong written and verbal communication skills.
  • Location: This internship is based on-site at the Mark Center in Alexandria, VA. All work must be performed on site – no teleworking opportunities.

  • Hands-On Experience: Prior experience working in a SOC environment or a Computer Incident Response organization is strongly preferred. Experience from home labs, CTF competitions, or class projects is also highly desirable.
