Information security, also known as InfoSec, is about protecting your data from hackers or system failures. A good InfoSec strategy will keep your data from being accessed or changed, maintaining its confidentiality, integrity, and availability.  

There are a lot of layers involved in a comprehensive information security strategy. Learning and implementing the intricacies involved in data security is no small feat.

What Is InfoSec?

Information security is an umbrella term that encompasses a wide variety of processes, technologies, and security protocols that protect sensitive data about a company, including its customers and staff.  

As such, not all information security strategies use the same tactics even though they’re all designed with three pillars of data security in mind:

  1. Confidentiality
  2. Integrity
  3. Availability

The Three Pillars of Information Security

As mentioned above, the three pillars of information security include confidentiality, integrity, and availability. Each of these pillars relies on a different set of tools and processes to secure and validate your data.  

Let’s take a closer look at the three pillars of information security individually.  


In information security, confidentiality refers to protecting your data from unauthorized access. It involves using encryption to mask data even if it were to fall into the wrong hands, establishing access controls that segment the network, and using secure communication channels.  

Keeping data confidential is vital when dealing with sensitive information like the personal data of customers and employees, financial records, or business strategies. If your data falls into the wrong hands, it can hinder operations, wreak financial havoc, and even impact the personal lives of your team.

Maintaining confidentiality requires a comprehensive approach, including multi-factor authentication protocols, encryption algorithms, and regular security audits. Organizations can also implement role-based access controls, restricting access to information based on an individual's role within the company and the data they need to do their job.  


The integrity of your data involves maintaining its accuracy, consistency, and reliability throughout its lifecycle.  

In the context of InfoSec, ensuring integrity means preventing unauthorized modifications or alterations to data. This pillar is essential for preserving the trustworthiness of information, especially in critical sectors like healthcare, finance, and government.  

Various mechanisms contribute to maintaining data integrity, including checksums, digital signatures, and version control.  

Checksums are hash functions that generate unique values for data, allowing users to verify its integrity. Digital signatures use cryptographic techniques to ensure that data has not been tampered with and can be traced back to its legitimate source. Version control systems track changes to documents, providing a historical record of modifications and enabling the restoration of accurate data.

If the data you’re basing your decisions on is corrupt, inaccurate, or unverified, the choices you make likely won’t produce the desired results. 


Availability is the third pillar of InfoSec, focusing on maintaining timely and reliable access to information and resources for authorized users.  

Downtime or disruptions in availability can have severe consequences, especially for businesses dependent on real-time data and services. Availability measures include redundant systems, disaster recovery plans, and network resilience. 

Redundancy involves creating duplicate systems or components to provide failover options in case of system failures. Disaster recovery plans outline procedures for restoring systems and data after a catastrophic event. Network resilience involves designing networks to withstand and recover from various types of failures, ensuring continuous availability even in challenging conditions. 

Creating an Information Security Strategy

Establishing a robust information security strategy is imperative for organizations to mitigate risks and safeguard their assets. A comprehensive InfoSec strategy encompasses various elements, including: 

  • Cyber Risk Assessment: Identifying and evaluating potential risks and vulnerabilities is the first step in developing an InfoSec strategy. This involves assessing the likelihood and impact of security incidents. 
  • Security Policies and Procedures: Clearly defined security policies and procedures guide employees and stakeholders on acceptable behaviors. This includes guidelines for data handling, password policies, and incident response procedures. 
  • Employee Training: Human error remains a significant factor in security breaches. Providing regular training to employees on security best practices, phishing awareness, and data protection is crucial. 
  • Incident Response Plan: Preparing for potential security incidents is essential. An incident response plan outlines the steps to be taken in the event of a security breach, minimizing damage and facilitating a swift recovery. 
  • Continuous Monitoring and Evaluation: InfoSec is an ongoing process. Continuous monitoring and evaluation help organizations adapt to evolving threats and ensure the effectiveness of security measures.

Crafting an information security strategy with these elements and the three core pillars in mind will give you the best chance at protecting the data of your organization, customers, and staff.  

Wrapping Up on InfoSec

Information security is a staple in modern network security practices focused on protecting organizations from data loss, theft, and corruption. With a suite of tools and processes dedicated to keeping data confidential, corruption-free, and readily available to those who need it, your business will be prepared for a data-loss incident.  

All-in-all, the quality of your data will ultimately affect the quality of your decision-making.  

One route you can take to establish and maintain the health of your network is through a strategic partnership with a managed service provider.
