Organizations looking to hire will often post on public job boards. These job postings may reveal information about the organization's personnel structure, technical environments, networking architecture, and other computing infrastructure. This is because the employer needs to both entice prospective employees and give them enough information to determine whether or not they should apply. The amount and type of information on these job postings is highly dependent on the organization's industry and the actual job they are hiring for. A network administrator position for a tech company might include more information about the technical side of the organization’s operations than a sales associate position at a retail business.

Some information you might be able to glean from job boards includes:

  • The personnel makeup of specific departments and teams.
  • The lack of qualified personnel in crucial positions.
  • The level of technical sophistication that the organization has.
  • The software architecture of the organization's technical services, like web server technology and cloud technologies.
  • The language that in-house software is programmed in.
  • The types and quantities of hardware that the organization employs.
  • The network and security systems that the organization employs.
