Security Control: Mitigating Cybersecurity Threats
The number of threats to information systems and networks has increased substantially in recent years, with organizations facing a wide range of challenges. From cybercriminals seeking to infiltrate a system to hackers attempting to exploit vulnerabilities, the threats to data security are numerous.
Enter security controls. Security controls are measures put in place to help prevent and mitigate cybersecurity threats. They are the first line of defense for organizations concerned with protecting their sensitive data.
In this article, we’ll explore what security controls are, the various types of security controls, and how they can be used to protect against cyber threats.
What are Security Controls?
In the world of cybersecurity, security controls refer to any mechanism designed to manage, regulate, or govern a system’s security. They can be physical, administrative, or technical. They are put in place to reduce the likelihood of unauthorized access to a system or network, and to ensure that data is safe from compromise.
Security controls are essentially safeguards aimed at protecting an organization’s assets from various threats. They help manage risks, prevent incidents, and respond to any vulnerabilities in a timely and effective manner.
Without security controls, organizations would be exposing themselves to a range of cybersecurity threats, including data breaches, phishing attacks, malware infections, and ransomware attacks. Security controls help ensure that these types of threats are kept at bay by mitigating the risks associated with them.
Types of Security Controls
There are three main categories of security controls: administrative, physical and technical. Each type of control is important for managing and regulating a system’s security.
Administrative security controls are policies, procedures, and guidelines that regulate the behavior of people within an organization. They are the most important type of security control for managing and governing a system’s security.
Examples of administrative security controls include security policies, security awareness training, access control management, and incident management. These types of controls help ensure that employees adhere to security guidelines and take the necessary precautions to protect sensitive data.
Physical security controls are mechanisms designed to physically secure an organization’s sensitive data and systems. These types of controls are important for preventing unauthorized access to sensitive data and for protecting against physical threats.
Examples of physical security controls include surveillance systems, door access controls, and biometric authentication systems. These controls help protect against threats such as theft, damage, or destruction of physical devices and systems.
Technical security controls refer to mechanisms that are designed to safeguard against cyber threats. They are used to control access to systems, regulate the flow of data, and protect against malware and hacking attacks.
Examples of technical security controls include firewalls, intrusion detection systems, antivirus software, and encryption. These controls help prevent and respond to cybersecurity threats by monitoring and detecting malicious activity.
How Security Control Works
Security controls are integrated into an organization’s security program in order to establish a comprehensive security posture. The implementation of security controls begins with a risk assessment, which identifies the vulnerabilities in an organization’s systems and data, and the potential risks associated with those vulnerabilities.
Once a risk assessment has been completed, an organization can select the appropriate security controls to mitigate those risks. For example, if the risk assessment identified a vulnerability in the organization’s network, technical security controls (such as firewalls and intrusion detection systems) would be implemented to prevent unauthorized access or malicious activity.
Each type of security control has a specific role in an organization’s security strategy. By combining administrative, physical, and technical controls, organizations can establish a layered security framework that provides comprehensive protection against cyber threats.
Here are some examples of how security controls have been used to prevent security breaches in different industries.
Healthcare: Healthcare organizations such as hospitals hold sensitive patient data, including personal information and medical records. In 2015, Anthem, the second-largest health insurer in the US, reported that over 80 million customer records had been compromised in a data breach. In response, the healthcare industry has implemented a number of security controls, including stronger passwords, access control measures, and encryption.
Finance: Financial institutions such as banks are also prime targets for cybercriminals. In 2019, Capital One, one of the largest credit card issuers in the US, announced that a data breach had resulted in the theft of over 100 million customer accounts. Financial institutions use security controls such as multi-factor authentication, intrusion detection systems, and encryption to protect against cyber threats.
Retail: Retail companies also hold sensitive customer data, including credit card numbers and personal information. In 2013, Target reported that hackers had stolen the credit and debit card information of over 40 million customers. Retail organizations use security controls such as point-of-sale terminal security, intrusion detection systems, and access control measures to protect against cyber threats.
In today’s world, security controls are a critical part of any organization’s cybersecurity program. By managing vulnerabilities and mitigating risks, organizations can protect sensitive data from cyber threats in a comprehensive and effective manner.
Security controls should be integrated into an organization’s security strategy, and implemented through administrative, physical, and technical controls. By doing so, organizations can create a layered security framework that effectively manages and regulates their security posture.
Ultimately, cybersecurity is about protecting assets from malicious actors. Security controls provide the front-line defense necessary to protect organizations from cyber threats, and ensure the safety and security of data and systems in our increasingly connected world.
