The increasing use of information technology in our daily lives and business has led to cyber attack increasingly sophisticated and on a larger scale. For organizations to thrive in this technology era, they must develop robust security strategies to detect and mitigate attacks. Dimensional defense deep is a strategy in which companies use multiple layers of security measures to protect assets. A well-executed defense of depth can help organizations prevent and mitigate ongoing attacks.
Advanced defense uses various advanced security tools to protect an enterprise’s endpoints, data, applications, and networks. The goal is to stop cyber threats, but a strong defense-intensive approach also stops attacks in progress and prevents further damage.
How organizations can deploy defense in depth
The image above shows the different layers of security that organizations must implement. Below, we describe ideas that companies should consider for each class.
Administration and risk management
Governance and risk management in cybersecurity revolves around three main factors; governance, risk and compliance (GRC). The overarching purpose of the GRC is to ensure that all members of an organization work together to achieve set goals. They must do this while adhering to legal and ethical principles, procedures and standards. These standards include NIST, PCI-DSS, HIPAA, and GDPR. Establishments must define the standards that apply to them and use tools to automate and simplify the compliance process. These tools must be able to detect violations and provide easy-to-follow reports and documentation to address violations.
Platform security
There are many ways organizations can ensure the security of the devices in their corporate network. The two essential methods are vulnerability management and OS hardening. Vulnerability management adds an extra layer of protection that ensures that companies address weaknesses in software before attackers can exploit them. On the other hand, strengthening the operating system ensures that security teams take additional measures to protect the integrity of the data and configuration used in an operating system. They can do this by defining and enforcing policies for endpoints in their network. Other factors to ensure platform security are firewalls and proper network segmentation implementation.
SIEM
A secure information and event management (SIEM) solution is essential to an organization’s security strategy. SIEM aggregates and compares logs from different sources and generates alerts based on detection rules. It also provides a central management portal for the classification and investigation of incidents, and being able to collect and normalize logs from different tools and systems is one of the essential features of a Good SIEM.
Peripheral security (threat information)
Successful implementation of defense in depth focuses not only on an organization’s internal infrastructure, but also on threat agent activities. Organizations must have a way to collect and analyze threat intelligence and use data to provide security for their assets. Security teams must also use firewalls and network segments to protect critical infrastructure.
Endpoint security
Endpoints within an organization are critical to its operations, especially in the 21st century. Endpoint security is critical as attackers often seek to compromise data stored on these sites. final point. Endpoint security has evolved over the years from anti-virus solutions to anti-virus solutions malware comprehensive and now we are in the era of extensible detection and response (XDR) solutions. XDRs go beyond the limits of traditional anti-malware solutions by comparing alerts from different sources to provide more accurate detection. They also leverage SIEM and SOAR (Security Orchestration, Automation, and Response) capabilities to detect threats across multiple endpoints and respond consistently and efficiently to any compromised endpoint. violate.
Wazuh, the free and open source solution
Wazuh is a free and open source security platform that provides unified SIEM and XDR protection. It protects workloads across on-premises, virtualized, containerized, and cloud-based environments. Wazuh provides support for security operations with easy integration with threat intelligence feeds.
In deploying defense in depth, no single tool can cover all layers of security. However, Wazuh offers many features that organizations can use to enhance their security infrastructure. For GRC, Wazuh provides dedicated dashboards that monitor and investigate events triggered by PCI-DSS, HIPAA, and GDPR violations. The solution also has a built-in vulnerability detection module with vulnerability feeds that scan operating systems and applications for known vulnerabilities.
Wazuh also provides a Security Configuration Assessment (SCA) module that allows users to create policies that the Wazuh server applies to every endpoint in their environment. Companies can use the vulnerability detection module and SCA to enhance the security of the operating systems and applications deployed on their terminals.
As an XDR, Wazuh correlates security data from a number of sources to detect threats in an organization’s environment. In addition, it can proactively mitigate threats using active response capabilities.
Wazuh is one of the fastest growing open source security solutions, with over 10 million downloads per year. Wazuh also provides communities where users can engage Wazuh developers, share experiences, and ask questions related to the platform. See this documentation on how to get started with Wazuh.
