How to Perform an Information Security Gap Analysis

The cyber threat landscape is ever-evolving, and the security controls that worked for your organization yesterday may no longer be sufficient today. Cyberattacks happen every second, and a security breach can result in the loss of clients’ confidential information, potentially leading to financial penalties and a damaged reputation.

What is Gap Analysis in Cybersecurity?

Information security gap analysis, also called IT gap analysis or cyber security gap analysis, refers to an in-depth review that helps organizations determine the difference between the current state of their information security to specific industry requirements. When you conduct a security gap analysis, you understand the status of your cybersecurity risks and vulnerabilities in your organization so you can work to close those gaps in your security.

Why is an IT Security Gap Analysis Important?

An information security gap analysis allows organizations to identify areas of weakness within their network security controls to ensure that the network is robust and effective. The cyber security gap analysis shows you what you should be doing by comparing your actual practices against industry best practices. It also offers insight into how your organization can put the correct structure and controls in place. You can reap many benefits from performing an information security gap analysis, but only when it’s done correctly.

What are the Main Causes of Cyber Security Gaps?

A cyber security gap can have many causes. In general, a lack of awareness about an organization’s internal controls can lead to these gaps. Notable security gaps include weak credentials, insider threats, outdated software, and malware. Thankfully, by building up awareness, you can reduce these gaps and lessen the chance of a data breach.

4 Steps for Conducting an Information Security Gap Analysis

To ensure that you effectively identify security risks and (note: remove link)vulnerabilities in your organization, it is important to conduct a gap analysis correctly. Here are the four necessary steps for every information security gap analysis:

1. Select an industry-standard security framework

By selecting an industry-standard security framework, you have the baseline best practices that you can measure and compare against your own security program. One of the most common frameworks is the ISO/IEC 27002 standard. This particular framework provides best practices on information security management, covering key security areas such as assessment, access control, physical security, change management, and more.

The ISO standard provides a great framework to compare your security policies and network controls against. However, it’s usually recommended that you leverage cybersecurity platforms to evaluate your security plan and ensure that (note: replace link) security measures are compliant with industry regulations. The reason is that cybersecurity platforms have automated tools that often catch gaps not found by people who are with the network on a daily basis.

When you select a cybersecurity platform to carry out an information (note: replace link) security assessment for your organization, it typically gathers data on your IT infrastructure, organizational charts, application inventory, policies and processes, and other relevant details. In doing so, it identifies and shows you which security policies are already in place, which outdated policies to replace, and what areas to implement them.

2. Evaluate your staff and processes

Many of the risks associated with (note: remove link)  security breaches are caused by human intervention, such as an employee unknowingly clicking on a phishing email.

Here are some of the typical questions that organizations should ask their key staff members:

• Do you provide staff training to keep your organization up to date on evolving security threats?
• Are there standard procedures and approvals required before a change is implemented? More importantly, is there a back-out procedure in case you run into a problem?
• How do you handle access for new hires and terminations?

When you know exactly how people are accessing your organization’s network and the existing security controls in place, it will be easier to execute the right information security analysis.

3. Gather data

Data gathering aims to understand how effective your security posture is operating within the technical architecture. During this step, your organizational controls are being compared to best practice standards (like ISO 27002 and NIST 800-53) and relevant compliance requirements. 

This allows you to see how your security process compares with other successful processes. To uncover gaps and vulnerabilities within your organization, take a sample of network devices, servers, and applications. 

Data gathering helps provide a holistic picture of your technical environment, the security measures already in place, and your overall security effectiveness. The data gathered during the process will help form a foundation for your IT gap analysis, allowing you to pinpoint areas that need improvement in your current security setup.

4. Analyze your security program

The last step is to perform a detailed analysis of your security program. If you choose to work with a cybersecurity platform, it can automatically correlate the findings across all factors to create your IT security profile, including strengths and areas of weakness where improvements are needed. 

With that information, the platform can make recommendations for a security plan that is right for your company. A robust security plan should consider (note: remove repeated link) cyber risks, staffing, budget requirements, and compliance timeframes to complete security improvements.

What is the Difference Between a Gap Analysis and Risk Assessment?

A gap analysis provides an overview of your current security operations and points out weaknesses when compared to industry standards. Whereas risk assessments analyze what could happen and what should be implemented to defend against cyber threats.

How SecurityScorecard Can Help You

By leveraging (note: replace link) cybersecurity questionnaires, your organization’s supply chain security team can effectively evaluate the strength of a vendor’s security posture. SecurityScorecard’s Security Questionnaires can help you cut your questionnaire cycle in half by providing automated cloud-based questionnaires in a secure and centralized platform. In doing so, you can more easily and efficiently identify gaps in security both for third-party vendors.

Additionally, the platform’s Security Ratings enable your organization to be more resilient and continuously monitor the overall health of the IT environment. When the insights gathered from Security Questionnaires and Security Ratings, you’ll gain complete visibility into the cybersecurity of your third-party  ecosystem, allowing you to stay better prepared for any future cyberattacks.
