Information Security Risk Management: An Overview
Friday, August 27th, 2010 | Author: admin

Information security risk management involves ensuring the implementation of data security standards in any organization. Information security risk is a big challenge for any company or organization that deals with permanent or temporary storage or transfer of information. Information security software that implement the information security program of an organization have become an important part of any organization worldwide.

What is Information Security Risk

There is no proper definition that may befit the description of an information security risk. In simple terms, an information security risk may be defined as any possible threat that uses a vulnerability in the system of an organization to cause disruption to the organizational routines and processes in some or the other form. An organization here refers to a large company or an individual entity or any entity that is responsible for processing or transfer of information.

Information Security risks may also be classified as threats that lead to a loss of any form to an individual or an organization. Such losses may include loss of privacy, identity theft, financial loss, negative impact on customer relations, loss or damage of confidential data or information, or a loss in profitability.

These risks mostly occur due to vulnerabilities in the system design. An information security vulnerability may be a weakness in the security design or processes of a system that can be exploited by unauthorized personnel to cause damage to the organization or entity.

A detailed description of information security risk can be found at Top Information Security risks for 2008 published in public interest by CISSPforum and ISO27k implementers’ forum in iso27001security.com.

Information Security Risk Management: Steps to be Followed

It is always good for organizations that have a large database and those dealing with large transactions of information, to set up their own information security management system or ISMS. This system would contain all good practices that are responsible for a fair and clean transfer of information.

Many individuals and organizations have been using Information Security Software to deal with information security risks. These software are helpful in many forms. They provide two separate modules, i.e., database security software and network security software. Both these modules help in different ways in protecting the data stored and the data or information being transferred from one end to another.

Information Security Risk Management involves the following major steps: risk identification, risk analysis, deploying measures to curb security threats and regular monitoring of security risks.

Risk identification and analysis are both important before any security risk management system can be deployed. The purpose of risk identification and analysis is to understand the possible threats that can be used against any possible vulnerability in the security architecture of the organization. Sometimes, an analysis may depict whether a security perimeter can be penetrated or not.

The next step would be risk assessment. Risk assessment is a step ahead of risk analysis. An assessment not only identifies a problem but also quantifies it i.e., it also measures the intensity of the security threat.

The next step is the major step. It involves management of risks. Designing security measures against known and possible threats is both time consuming and expensive. Sometimes, it requires making strategies to build a secure architecture or perimeter within which the transfer of information or storage of information takes place.

Summary

Most information security risk management systems are designed to comply with International standards that have been formulated to reduce the risk significantly. These systems try to build safe and sound information transfer methods and environments. Also, these systems keep monitoring the system for a new possible threat against which the system needs protection. Continuous development and updating of these software or systems makes them expensive and time consuming.
