The Importance Of Specialized Roles In Cybersecurity

The security landscape needs to stop lumping everyone into a security role. For instance, Engineers performing security engineering SHOULD NOT be doing tickets with the L1-3. In addition to which, just because your plumber knows how to bust up your wall to fix your tub doesn’t mean he’s gonna do sheetrock work. There are workers that handle that. I blame managers, HR, and greedy VPs.
