What is Enumeration in Cyber Security?

Cyber security enumeration is a process used by both security professionals and attackers alike to establish a collective knowledge of the target and its assets. Using this knowledge specific attack vectors can be used to target weak points that exist based on the information gathered.



Types of enumeration

Enumeration can take many forms but a typical enumeration phase will collect the following information:

  • IP Addresses and network resources

  • Subdomain enumeration

  • Site locations

  • Machine names

  • Operating systems in use

  • Usernames

  • Configurations

  • Leaked passwords

  • Corporate services exposed to the internet

Enumeration tactics are varied and can take the form of extracting data from social media, collecting company documentation online and extracting leaked information from the headers of files. Operating system information can be disclosed unintentionally by the configuration of web services. Additionally, corporate web applications can reveal detailed information about the company and its resources.
