What is Information Security Analysis?

As enterprise information technology systems have become the repository for critical proprietary business intelligence and corporate espionage methods have become more sophisticated, IT security systems have grown in complexity.  Information security analysts must possess a thorough understanding of all network components and recognize any characteristics that may undermine security integrity.  In order to anticipate and recognize potential threats to the system, analysts must remain up to date on the latest security threats, software and network vulnerabilities, and the latest tools and methods that unscrupulous actors may use to gain access.

The primary role of information security analysts is to prevent unauthorized access to information stored on computing devices and networks. They also serve as damage control professionals that identify security weaknesses and create robust defenses if security is compromised.

As an expert in information and network security, information security analyst jobs involve anticipating external and internal threats, developing comprehensive security strategies, and collaborating with software and equipment manufacturers to identify and neutralize system weaknesses.

An information security analyst’s job also involves conducting cyber forensic investigations to produce summary reports for management and law enforcement agencies.

  • Remain informed about personnel access, equipment and software specifications, network implementation, and industry security best practices.
  • Research available information about security threats including malware, viruses, and other forms of cyber-attack.
  • Develop monitoring programs that record use of network and information.
  • Implement training programs that instruct users on methods of data access that minimize security impairment.
  • Analyze possible threats and provide accurate estimates of system vulnerability.
  • Generate simulations of a cyber-attack to identify system weaknesses.
