Information Security Lifecycle Model (ISLM) is a standard developed by the International Organization for Standardization and International Electrotechnical Commission. Over 60 countries have adopted it to provide an overall model for information security.

The information security program lifecycle is defined as steps or phases that organizations must complete to secure their networks.

The following diagram shows the typical stages of an information security program.

Information security has always been a critical concern of businesses, and they should always take it seriously.

It is essential to understand that information security is a continuous effort, and an organization may need to reevaluate its existing programs and policies.

In this article, I’ll share with you some of the essential steps of the information security program lifecycle.

A secure information system, no matter what the size, will need to be managed and maintained throughout its life cycle. A company will face an ongoing challenge to keep its systems and networks safe and secure at any point in time. The process begins with a plan, which includes activities, tasks, and goals that define the security program for a given period. To execute these plans effectively, an organization must have a clear vision and the right resources.

Planning phase

During the planning phase, the business must decide on the type of information security strategy to employ and what measures they need to take to ensure security is maintained at all times.

In this phase, businesses usually plan how they can secure their networks and who needs to be involved in the process.

Once they have decided on the right strategy and have put together the team, the next step is to develop a formal program.

In the planning stage, the business has to make sure that they have all the resources they need, along with the proper personnel. They also have to understand their vulnerabilities and risks and how to address them.

Implementation phase

The implementation phase of a security program involves identifying the threats and vulnerabilities on the network and installing the necessary measures to prevent further attacks.

A typical organization would start by scanning the network with a vulnerability scanner and then assign a vulnerability assessment specialist to identify and prioritize the vulnerabilities.

In addition, a firewall and intrusion detection system (IDS) should be installed to prevent unauthorized access to the network.

The program’s final phase is to regularly audit the network, ensuring that no new vulnerabilities have been identified.

It is important to note that this process is ongoing and never complete. The goal is to improve the security posture of the network continuously.

Monitoring phase

Once you have decided to develop an information security program, you should start planning. The most important thing is to determine what phase you will be at and how you will achieve that phase.

It is always better to plan and understand the process and requirements of the company before starting the actual procedure.

Here are some of the steps involved in the monitoring phase:

– Planning the program

– Identifying the vulnerabilities

– Determining the threat assessment

– Determining the countermeasures

– Determining the required resources

– Evaluating the risks

Developing the plan

– Implementation

– Evaluation

Maintenance phase

While the initial phases of securing an IT infrastructure are generally focused on hardening and defending against threats, the maintenance phase ensures that the security programs are effective.

The goal of the maintenance phase is to maintain and improve the security posture of an organization’s network. It includes reviewing and updating policies, updating security patches and software, monitoring security devices such as firewalls and intrusion prevention systems, reviewing audit logs, and ensuring no loopholes in the security system.

 Frequently asked questions About security program lifecycle

Q: What is the goal of the information security program lifecycle?

A: The goal of the lifecycle is to develop a program that ensures that all activities within the organization are conducted in a safe manner.

Q: Where does the information security program lifecycle start?

A: The lifecycle starts with the risk analysis phase. In this phase, it is determined what risks are present within the organization. In addition, it is determined how each risk is handled. For example, if an attack occurs, we would decide what actions need to be taken. We might look at where it is most vulnerable, or we may identify the people who would be most likely to be affected by an attack.

Q: What is the second step?

A: The second step is designing. This is where the organization creates the program. It determines the types of resources needed, the rules and regulations that must be followed, and the required training.

Top Myths About security program lifecycle

1. The first step of the information security program lifecycle is to educate people.

2. The second step of the information security program lifecycle is to inform people.

3. The third step of the information security program lifecycle is to protect people.

4. The fourth step of the information security program lifecycle is to keep people safe.

Conclusion

It’s hard to keep up with the constant changes in cybersecurity threats. The best way to stay ahead of the curve is to look at your security program and make sure it’s current and effective.

With that in mind, I’ve put together this simple guide to show you the five stages of the security program lifecycle.
