5. Corrective Controls: These controls are put in place to correct or mitigate any security issues that were identified by the detective controls. Examples of corrective controls are system patching, data recovery, and incident response plans.
Introduction
Cyber security is a crucial aspect of any organization that handles sensitive information, whether it is financial records, client data, or intellectual property. There are numerous threats that can jeopardize the security of an organization’s digital systems, making it essential to implement appropriate security controls. There are five primary types of security controls that organizations can employ to protect their digital systems and assets. These include firewalls, secure configuration, control of access to users, malware protection, and management of patches. Each one plays a critical role in safeguarding against cyber threats.
Firewalls as Security Controls
A firewall is a network security tool that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a private network and the internet, filtering traffic to prevent unauthorized access, and blocking potentially harmful traffic from reaching the network. Firewalls can be implemented as both hardware and software, and there are several types of firewalls that can be deployed, including stateful firewalls, packet filtering firewalls, and application-level gateways.
Organizations can employ firewalls as a security control to protect their network infrastructure and prevent unauthorized access. With the rise of remote work due to the pandemic, firewalls have become more critical than ever to protect sensitive data and digital systems from cyber-attacks. Lack of a firewall can expose an organization to numerous cyber-attacks. For example, a DDoS (Distributed Denial of Service) attack can take down a website, disrupting normal operations and potentially costing the company millions.
Key Points:
- Firewalls monitor and control incoming and outgoing traffic.
- They act as a barrier between a private network and the internet.
- Firewalls can prevent unauthorized access and block harmful traffic from reaching an organization’s network.
Secure Configuration as a Security Control
Secure configuration refers to the process of implementing security settings on devices and software applications to reduce the risk of a cyber-attack. By applying secure configuration settings, an organization can minimize its exposure to cyber threats. Secure configuration involves tasks such as hardening servers, disabling non-essential services, and securing user accounts with strong passwords.
Organizations can employ secure configurations as a security control to prevent attacks that exploit vulnerabilities in software and devices. For example, a cybercriminal can exploit a known vulnerability in a server’s configuration to gain unauthorized access to the network. Through secure configuration settings, organizations can minimize their exposure to such attacks and increase their security posture.
Key Points:
- Secure configuration involves applying security settings to devices and software applications.
- It reduces the risk of cyber-attacks.
- Secure configuration includes tasks such as hardening servers, disabling non-essential services, and securing user accounts.
Control of Access to Users as a Security Control
Control of access to users involves implementing policies that govern which employees have access to specific information within an organization. The goal is to ensure that only authorized personnel can access sensitive data and information. Access control policies can be implemented using various tools and technologies, such as employee training, passwords, biometric authentication, and identity and access management (IAM) systems.
Organizations can employ this security control to prevent unauthorized access to sensitive data, helping to protect it from cyber-attacks. For example, if an employee leaves the organization or changes roles, access to certain types of data may need to be revoked to ensure that the person cannot access information that they no longer require. Such measures will ensure the organization remains secure and the data is protected from potential cyber-attacks.
Key Points:
- Control of access to users involves policies that determine who has access to specific information.
- Access control policies can be implemented using various tools such as passwords, biometric authentication, and IAM systems.
- Access control helps prevent unauthorized access to sensitive data.
Malware Protection as a Security Control
Malware protection involves taking measures to protect digital systems from various types of malware, including viruses, worms, and Trojans. Malware is malicious software designed to compromise the security of a system and steal data without the user’s knowledge. Malware can enter a system in several ways, including phishing emails, infected software, and malicious downloads.
Organizations can employ malware protection as a security control by implementing anti-malware software and educating users on how to avoid common phishing attacks. Regular vulnerability scans and penetration testing also fall under this security control. By employing these measures, organizations can prevent malware attacks and safeguard their systems and data from unauthorized access.
Key Points:
- Malware protection involves measures to protect digital systems from various types of malware.
- Anti-malware software, education of users, and regular vulnerability scans are critical in malware protection.
- Malware protection helps prevent unauthorized access to data and sensitive information.
Management of Patches as a Security Control
Management of patches is a security control that involves the regular updating of software systems to fix security vulnerabilities. Software developers regularly release patches to fix known security vulnerabilities, and it is vital that organizations apply these patches as soon as possible. Delaying the installation of patches can increase the risk of cyber-attacks, as attackers can exploit these vulnerabilities to gain unauthorized access.
Organizations can employ management of patches as a security control by having a well-defined patch management process that is regularly reviewed and updated. This process can include automated patch deployment, test environments, and documentation that tracks the history of all patches deployed.
Key Points:
- Management of patches involves regular updating of software systems to fix security vulnerabilities.
- Organizations can employ a well-defined patch management process to minimize the risk of cyber-attacks.
- Delaying the installation of patches increases the risk of cyber-attacks and exploitation of vulnerabilities by attackers.
Conclusion
In conclusion, organizations must implement a combination of security controls to minimize the risk of cyber-attacks and safeguard sensitive information. The five primary types of security controls are firewalls, secure configuration, control of access to users, malware protection, and management of patches. While each one individually plays a critical role, they work best when implemented together in a comprehensive cybersecurity strategy. Organizations must evaluate their cybersecurity needs and develop a detailed plan to protect themselves from current and future cyber threats. By doing so, organizations will ensure their digital systems and data remain secure.
