The assessment may use a subjective qualitative analysis based on informed opinion, or where reliable dollar figures and historical information is available, the analysis may use quantitative analysis. Include: people, buildings, hardware, software, data (electronic, print, other), supplies. An incident log is a crucial part of this step. Information technology and network infrastructure are targets for malicious activity on a regular basis. Thus, any process and countermeasure should itself be evaluated for vulnerabilities. Not all information is equal and so not all information requires the same degree of protection. This is largely achieved through a structured risk management process that involves: To standardize this discipline, academics and professionals collaborate to offer guidance, policies, and industry standards on password, antivirus software, firewall, encryption software, legal liability, security awareness and training, and so forth. Software applications such as GnuPG or PGP can be used to encrypt data files and email.
