Every organization needs an information security plan because data has become the world’s most valuable commodity. And like all things precious, data is regulated heavily by governing bodies and coveted by everyone – including crooks. That is why cybercrime is on the rise – in step with a tightening compliance landscape.

The latest outlook is alarming: the vast majority (83%) of companies will more than likely experience at least one data breach in their lifetime. just a single intrusion can very well be the final showstopper to many inadequately capitalized businesses. As reported by IBM, the average data breach cost was US$4.35 million in 2022. (The impact could leave a larger crater in your wallet – around US$9.44 million – if your business operates in the U.S.) With more organizations getting goosed by cybercrime, the information security market will balloon to around US$175 billion by 2024, as forecasted by Statista. Still, malicious hackers account for just a portion of the aggregate risk to data security.

Companies need to include natural disasters, human error, system flaws, and a slew of noncompliance penalties in their data protection strategy. There is no feasible way around this dilemma because most businesses today need to process and store data – their own, their vendors, and their customers. And like those old-school institutions, modern businesses must guard their precious currency (i.e., data) as if everything depends on it. The best way to do that is to start with a strong information security plan.

What Is Information Security?

Information security (InfoSec) refers to practices, processes, and tools that manage and protect sensitive data. Its primary aim is to control access to information that upholds the CIA triad in data protection (Confidentiality, Integrity, Availability) without significantly hampering business productivity.

Here’s how key institutions define information security: “The preservation of confidentiality (ensuring that information is accessible only to those authorized to have access), integrity (safeguarding the accuracy and completeness of information and processing methods), and availability (ensuring that authorized users have access to information and associated assets when required).” – ISO/IEC 27002 “Ensures that within the enterprise, information is protected against disclosure to unauthorized users (confidentiality), improper modification (integrity), and non-access when required (availability)” – ISACA.

What is an Information Security Plan?

An information security plan refers to the documented set of policies, objectives, systems, and processes that an organization has established to protect sensitive data. Such a plan includes security measures, authentication methods, and response protocols for mitigating risks and addressing active threats that could undermine a company’s data integrity, confidentiality, or availability.

Why Do You Need an Information Security Plan?

An organization must have an information security plan to participate in the digital economy. The peril such an organization poses extends far beyond its own business into those of its customers, suppliers, and other entities that transact with it. Cybercrime – particularly data breaches – can target complex supply chains where data flow is difficult to track and secure. If you exchange sensitive data with an entity with poor information security measures, threat actors can easily compromise your data. That is why many prudent companies (and almost all investors) require concrete assurances (such as ISO certifications and SOC reports) from vendors, third parties, and potential investees on how well they protect data before going forward with any business.

An information security plan helps establish the process by which a company can obtain those concrete assurances. Ultimately, a well-designed information security plan benefits the company on multiple fronts: a) it helps reduce the likelihood of unauthorized exposure (confidentiality), corruption (integrity), and unintended inaccessibility (availability) of data. Implemented the right way, an information security plan helps an organization more easily comply with regulatory mandates and industry standards, thereby avoiding costly penalties and lost opportunities due to noncompliance.

How Do You Create a Good Information Security Plan?

Here are some essential steps to help you build a strong information security plan.

Form an information security team

Hands down, this should be the first step for most organizations yet to develop an InfoSec plan. That’s because information security was meant to be something other than a solo venture. It requires sustained collaboration among stakeholders and IT security experts who will focus on protecting your company’s data or processes. You need competent and dependable people to build and manage the information security infrastructure for your company, including a dedicated team tasked and trained to respond to security incidents (i.e., the Cyber Security Incident Response Team, or CSIRT).

Audit and classify your data assets

You can only protect something if you know what and where it is. Conduct a comprehensive inventory of your IT assets and the designated custodian for each. Include all hardware, software, databases, systems, and networks your organization uses (or is in possession of). Classify your data assets based on their nature, how they are stored and accessed, and the vulnerabilities, risks, and existing protections associated with those assets. Your InfoSec team must know where data is stored, who is authorized to access said data, how it is processed, and how it is protected. Additionally, some types of data need stronger protections, including PII (Personally Identifiable Information), PHI (Protected Health information), and NPI (Non-Public Information).

Evaluate risks, threats, and vulnerabilities

Conduct a thorough review of the systems and networks that store and process data to detect, identify, and assess security weaknesses, risks, threats, and vulnerabilities. Categorize and prioritize those risks and vulnerabilities. Some common areas for improvement include outdated hardware, unpatched software applications, and inadequate IT security awareness training for staff. Your team should also assess the IT security measures your company already has in place. You can use tools such as the Cybersecurity Framework developed by the National Institute of Standards and Technology (NIST) to help you cover all the essential grounds. Your cyber risk assessment must include not only your internal systems but also those of third parties that conduct business with your organization. Make a list of requirements/standards (such as SOC II compliance) third-party entities need to meet before they can do business with your organization.

Address weak points in your information security posture

That is where you plug the holes in your defensive layer and improve your overall security posture. The objective is to eliminate risks that can be neutralized and to minimize those that can’t be removed completely, starting with the most serious threats and vulnerabilities down to the ones with the least potential impact on your business. Depending on your specific requirements, you can consider solutions that can help augment and reinforce your information security policies, including MDR (managed detection and response) and security monitoring services.

Scan the regulatory and standards landscape

Depending on your line of business, location, customer demographic, and other factors, your organization is subject to a number of regulatory mandates, industry benchmarks, and self-imposed standards. These include mandatory IT security practices required by The Health Insurance Portability and Accountability Act (HIPAA), The General Data Protection Regulation (GDPR), and the Payment Card Industry Data Security Standard (PCI DSS). Some external stakeholders, such as business partners, independent auditors, and potential investors conducting due diligence, may also require specific compliance practices and detailed documentation. Make a thorough review of the landscape and determine which regulations, mandates, and standards are relevant to your organization.

Develop a compliance plan

Over the years, regulatory compliance has grown in relevance and complexity, and it now requires organizations to develop and implement a comprehensive and coherent compliance program. Given the tightening regulatory environment around the world, not doing so can be very costly. For example, noncompliance with a GDPR mandate in 2021 cost Amazon nearly US$781 million in fines. The cost of breaching local market regulations can also be prohibitive, as is the case with Citigroup, which was slapped by the U.K.’s Financial Conduct Authority (FCA) with a US$15 million fine for violating one of the regulator’s core principles. Managing your compliance risks can help you avoid getting into either situation. Once you have identified your regulatory and standards requirements, map your compliance needs with the appropriate practices and technology solutions to bridge any gap in your company’s regulatory profile.

Develop an incident management and disaster recovery plan

In context, “incidents” refer to events and situations that can lead to any violation of the CIA triad for information security. Such events include cyber attacks, natural disasters, human error, system malfunctions, and other situations that can cause corruption, unauthorized disclosure, or unintended data inaccessibility. A well-designed incident management and recovery plan outlines all potential risks, mapping each to the organization’s corresponding response strategy to minimize damage and resume normal operations as fast as possible when a major disruptive incident occurs. Detailing your response strategy for each incident type can help your team and other stakeholders to react calmly, orderly, and confidently to each threat. Many organizations link this step with their overall Business Continuity Plan.

Equip and train your people

Your people remain your first line of defense when all has been said and done. Quite often, however, they can also be the weakest link in your security infrastructure, being the attack vector favored by most cybercriminals. Hence, staff training should be integral to any information security plan. By continually training your people in IT security, they can become effective assets in your fight against all sorts of information security risks.

Conduct regular audits, vulnerability assessments, and penetration tests

A plan can be good or bad, sufficient or inadequate. But you would know once something puts your plan to the test. Would you rather have an actual, potentially disruptive incident – with all its unpredictable ramifications – prove your plan’s worth, or have an independent security firm objectively but safely test it for you? Technology and compliance audits, vulnerability assessments, and penetration tests are your best friends in detecting (and addressing) weaknesses in your armor and keeping your information security infrastructure well-provisioned, up-to-date, and on par with emerging risks in the threat and compliance landscape.

Final Takeaway

Building and documenting an information security plan can be a monumental task for many organizations, especially those struggling to keep pace with the digital economy and the regulatory and industry standards that relentlessly evolve with it. You can choose to have your team do all the heavy lifting or seek expert guidance from specialist service providers. Doing so will help fast-track the process by ditching a costly trial-and-error approach in favor of a best practice-driven framework. An information security plan should provide a snapshot of how data is protected across your network and how your team will respond to different types of risk that threaten its confidentiality, integrity, and accessibility.
