by Jennifer Balsom Marketing Head

With the boundless increase in the number of computers and devices connected to the internet, maintaining information security has become a major challenge for the information security professionals. It is an on-going process that requires effective execution of every single phase of the information security lifecycle. Regardless of the type of the organization or the industry focus, understanding the diverse phases of information security lifecycle can serve as a roadmap, ensuring improved security standards.

The Information Lifecycle

The information lifecycle consists of four phases.

Effective Planning and Organizing: This phase requires security professionals to evaluate the existing networking infrastructure, individual servers and hosts, software versions, operating systems, and network devices to understand the organization’s IT architecture. It is a crucial phase in the information lifecycle, that helps you to determine the areas requiring immediate attention. It aims to assess the current security standards and analyze the flow of data and information over the network and devise a plan accordingly to fix the issues if any.
Acquire and Implement: After analyzing the organization’s IT infrastructure, this phase of the information lifecycle requires you to identify and implement appropriate security measures. A thorough vulnerability assessment must be done, focusing on the areas where certain risks were identified in the initial phase. It also includes defining effective security policies and implementing the formulated plan to mitigate the risks to safeguard organizational data and information security.
Execute Plan and Deliver: This phase involves actual implementation of the devised plan and security strategy. With prime objective of maintaining information security, the security software must be upgraded, necessary changes must be made in the hardware, and obsolete technology must be discarded in view of the budgeted cost and security policies of the organization. This phase ensures to strengthen every network component and 100% compliance with organization’s security policy and procedures.
Monitor and Evaluate: This phase confirms the cyclical nature of the process. It deals with monitoring and evaluation of applied security plan. The stage requires to deploy security monitoring and management programs to ensure compliance and identify the deviations if any. The deviations must be addressed systematically to result in secured IT infrastructure. The process repeats itself from the beginning while addressing the security compliance issues as observed at the final stage.

Maintaining security standards of organization’s IT infrastructure is a role that requires constant updates on the newer technological security trends, risks, recent developments in security programs, tools, and devices. Henceforth, the role of security professionals is highly crucial in terms of building and maintaining high-security standards for data and information security in the organization.
