IT Security vs IT Compliance: What’s The Difference ?


What is IT security?
Security officers follow industry best practices to secure IT systems, especially at the organizational or enterprise level. Security pros are constantly looking at how to both:

Prevent attackers from harming the company IT infrastructure and business data
Mitigate the amount of damage that is done when an attack is successful
In the past, administrators would take a purely technical approach and rely heavily on systems and tools to protect their network. Today, though, things have changed.

Due to increased specialization and technical know-how, IT security is not limited to a single field or discipline. Instead, there are multiple areas such as architecture and infrastructure management, cybersecurity, testing, and especially information security—arguably the most critical policy for any organization.

Information security (InfoSec) is exercising due diligence and due care to protect the confidentiality, integrity, and availability of critical business assets, something security pros know as the CIA Triad. Any IT security program must take a holistic view of an organization’s security needs and implement the proper physical, technical, and administrative controls to meet those objectives.

Taking the three key functions of confidentiality, integrity, and availability, organizations can implement effective InfoSec protocols. But what does CIA actually mean?

Here are three key sections in understanding how InfoSec must be managed.


Company information can be sensitive information—customer data, proprietary information, innovations in the works. It is the duty of IT security to protect this information. Ensuring that only the correct and authorized user(s) and system(s) can read, change, and use data is key.


Information and the system it is contained in must be correct. Having integrity means knowing that what is stored is correct and the system has measures to ensure that.


Systems and information need to be available when they are needed. If a system isn’t available, it can’t be relied on.

Two additional properties, authentication and non-repudiation, are also vital to IT security.

How IT security looks today
Traditionally, security professionals would rely on devices like firewalls and content filters along with network segmentation and restricted access. But as modern threat agents became more and more sophisticated, the tools that security analysts and officers have to use become more complex too.


What is IT compliance?

IT compliance is the process of meeting a third party’s requirements with the aim of enabling business operations in a particular market or aligning with laws or even with a particular customer.

Compliance sometimes overlaps with security—but the motive behind compliance is different. It is centered around the requirements of a third party, such as:

Industry regulations
Government policies
Security frameworks
Client/customer contractual terms

Let’s say that IT security is a carrot. it motivates the company to protect itself because it is good for the company. IT Compliance, then, is the stick—failure to effectively follow compliance regulation can have serious effects on your business.

Often, these external rules ensure that a given organization can deal with complex needs. Sometimes, compliance requires an organization to go beyond what might be considered reasonably necessary. These objectives are critical to success because a lack of compliance will result in:

At minimum, a loss of customer trust and damage to your reputation.
At worst, legal and financial ramifications that could result in your organization paying hefty fees or being blocked from working in a certain geography or market.
Areas where compliance is a key business concern:

Countries with data/privacy laws like GDPR, the California Consumer Privacy Act, and more
Markets with heavy regulations, such as healthcare or finance
Clients with high confidentiality standards
These areas almost always demand a high level of compliance. Importantly, IT compliance can apply in domains other than IT security. Complying with contract terms, for example, might be about how available or reliable your services are, not only if they’re secure.

When is compliance necessary?

When you need to comply with certain regulations depends on many factors:

Your industry
Your company’s size or location
The customers you serve
Many other factors
Many laws outline very specific criteria that a business must meet—but they don’t apply to everyone. For example:


Comparing IT security & IT compliance

Security is the practice of implementing effective technical controls to protect company assets. Compliance is the application of that practice to meet a third party’s regulatory or contractual requirements.

Here is a brief rundown of the key differences between these two concepts. Security is:

Practiced for its own sake, not to satisfy a third party’s needs
Driven by the need to protect against constant threats to an organization’s assets
Never truly finished and should be continuously maintained and improved
Compliance is:

Practiced to satisfy external requirements and facilitate business operations
Driven by business needs (rarely technical needs)
“Done” when the third party is satisfied
At first glance, it’s easy to see that a strictly compliance-based approach to IT security falls short of the mark. This attitude focuses on doing only the minimum required in order to satisfy requirements, which would quickly lead to serious problems in an age of increasingly complex malware and cyberattacks.

How security & compliance work together

We can all agree that businesses need an effective IT Security program. Robust security protocols and procedures enable your business to go beyond checking boxes and start employing truly effective practices to protect its most critical assets.

This is where concepts like defense-in-depth, layered security systems, and user awareness training come in, along with regular tests by external parties to ensure that these controls are actually working. If a business were focused solely on meeting compliance standards that don’t require these critical functions, they would be leaving the door wide open to attackers who prey on low-hanging fruit.

While compliance is often seen as doing only the bare minimum, it’s useful in its own right. Compliance is an asset to the business—it isn’t just hoops you must jump through. Becoming compliant with a respected industry standard like ISO:27001 can:

Bolster your organization’s reputation
Garner new business with security-minded customers
Compliance can also help to identify any gaps in your existing IT security program which might not have otherwise been identified outside of a compliance audit. Additionally, compliance helps organizations to have a standardized security program, as opposed to one where controls may be chosen at the whim of the administrator.
