Understanding the Essentials: What is a Security Control?

What is a Security Control? Keeping Your Digital Life Safe

In the past few decades, the rise of technology has brought about countless benefits to our daily lives. However, as technology advances, so does the danger of cybercrime. With cybercriminals becoming more sophisticated, it is more important than ever to take the necessary precautions to protect our digital lives.

One of the primary ways to defend against cyber attacks is through security controls. In this article, we will discuss what security controls are, the different types of security controls, and how they play a critical role in keeping your digital life secure.

What are Security Controls?

A security control refers to any measure taken to manage risk and reduce any potential threat to an organization's assets. Security controls encompass a broad range of activities, from software applications to physical barriers designed to prevent unauthorized access. Security controls can be found in almost every business or organization that processes and stores valuable data, ranging from small startups to multinational corporations.

The Importance of Security Controls

Nowadays, businesses are faced with a wide range of digital security threats, such as viruses, malware, hackers, Denial of Service (DoS) attacks, and cyber espionage. By implementing security controls, businesses and organizations can significantly reduce the risk of a data breach, cyber attack, or other security incidents.

Security controls play an essential role in enabling trust in technology. They provide a level of assurance that assets have necessary security measures in place to protect them, reduce the impact of an incident, and increase the likelihood of detecting and responding to security threats promptly.

Types of Security Controls

There are three primary types of security controls: administrative, physical, and technical. Each type of security control plays a crucial role in protecting sensitive data from unauthorized access.

Administrative Security Controls

Administrative controls are the policies and procedures that organizations put in place to minimize the risk of accidental or intentional loss, theft, corruption, or misuse of information systems.

Administrative security controls include:

Security awareness training: This type of training educates employees on how to identify and avoid phishing scams and other types of cyber threats.

Access control policies: Password policies, two-factor authentication, and other procedures are used to restrict access to sensitive data and ensure authentication of users gaining access.

Security incident response plans: These strategies outline how an organization should respond in the event of a security incident, who should be notified, and what steps should be taken to contain the threat.

Physical Security Controls

Physical controls refer to the physical barriers that organizations put in place to secure its facilities, equipment, and personnel from any unauthorized access.

Physical security controls include:

Security cameras and alarms: These devices help monitor and protect physical assets and deterring potential security breaches.

Locked doors and gates: Access controls should play a vital role in limiting entry into areas where sensitive data is stored.

Biometric authentication: Examples can include fingerprint or retina scanners, which allow only authorized personnel access to sensitive areas.

Technical Security Controls

Technical controls are the security measures put in place that are designed to protect data and systems from intentional or accidental unauthorized access. Technical controls include hardware and software systems that limit access, monitor activities, and safeguard data.

Technical security controls include:

Antivirus software: This software aims to protect networks and devices from malware and viruses.

Firewalls: These hardware or software-based security systems can monitor and control incoming and outgoing network traffic.

Encryption: Encryption makes text unreadable to anyone unauthorized through the use of mathematical algorithms.

Intrusion detection systems: These systems look out for anything unusual happening within the network, such as unauthorized users or strange traffic patterns.


In conclusion, security controls are essential defences against cybercrime. Security controls provide the necessary foundation to help organizations mitigate risks, prevent attacks, and safeguard critical assets. The combination of administrative, physical, and technical controls can provide a significant level of assurance that sensitive data is kept safe.

As the world becomes increasingly digital-centric, it will only become more critical for organizations and individuals to put effective security controls in place to reduce the risk of cyber-attacks, data breaches, and cyber theft. Ultimately, this is the best way to ensure the safekeeping of your digital life.
