Electronic information systems and network security go hand-in-hand for businesses and organizations. Because these systems are commonplace for storing files and data, industry regulations have specific standards for them, including network security implementation and risk assessments.
Network security, regardless of industry standards, encompasses all activities for protecting system data, including technical, physical, and social. Small and medium-sized businesses are particularly vulnerable to security threats, and to take precautions, such organizations need to conduct regular network risk assessments.

Risk management should follow a structured process acknowledging many aspects of the IT operations process, with special considerations for security and systems availability.
IT risk management has been neglected in many organizations, possibly due to the rapid evolution of IT systems, including cloud computing and implementation of broadband networks. When service disruptions occur, those organizations find themselves unprepared for dealing with the loss magnitude of the disruptions.
A network risk assessment involves penetration testing, social engineering, and vulnerability audits. Vulnerabilities, or weak points present along a system’s perimeter and in the interior, allow intruders to enter, and a network engineer identifies and tests these points for their strength. In assessing your network, the engineer may interview employees to test judgment, perform vulnerability scans, examine operating system settings, use ethical hacking techniques, and analyze past system attacks. As he or she examines these aspects of your network, the following information is gathered:
- How security policies are used and implemented
• Access control lists and their location
• Audit logs and their review
• Passwords and how easy they are to retrieve
• Security settings
• Compliance with industry best practices, such as HIPAA or FFIEC
• Unnecessary applications and their removal
• Operating systems, including consistency and being up to current levels
• Backups, such as how all information is stored, if it is up to date, and how easy information is to access
• A disaster recovery plan, if one is in place
• Sufficiency and configuration of cryptographic tools for data encryption
• Any custom-built applications and if they correspond with network security policies
Steps involved in Network Risk Assessment:-
The basic steps to risk assessment are cataloging resources, ranking resources, identifying vulnerabilities, and eliminating.
- The first step to network risk assessment is to catalog your resources. By recording the different software and their assets and capabilities of a system those performing the assessment can more accurately identify problems.
- The second step is to rank in order of importance these assets and capabilities of the software. This allows for executives to examine overlapping capabilities and make important decisions in regards to the deletion of corrupted files.

- The third step is to assess each of the resources for their vulnerabilities and potential threats that may arise. Having this information allows business owners to evaluate the vulnerabilities in the system and begin to make any final decisions.
- The final step in network vulnerability assessment is to fix any corruption within the systems.
