2021 was a year peppered by cyberattacks, with numerous data breaches happening. Not only that, but ransomware has also become a prominent player in the hackers’ world.
Now, more than ever, it’s important for enterprises to step up cybersecurity measures. They can do this through several pieces of technology, such as an open-source security platform like Wazuh.
Wazuh is a free and open source security platform that unifies XDR and SIEM capabilities, which not only enables companies to detect sophisticated threats, but can also help immensely in preventing data breaches and leaks from happening. It can help businesses avoid costly repairs that could ultimately lead to their closing.
Wazuh can also be integrated with other services or tools. VirusTotal and YARA are just a few of the many tools that can be used to integrate Wazuh with external services. Consequently, companies can improve their security against hackers from penetrating their networks.
What’s amazing about Wazuh? It’s open-source, scalable and completely free. It can compete with many high-end cybersecurity solutions that are available for a lot of money. This can be a huge budget saver for SMEs.
Read on to find out more on how Wazuh can help with cybersecurity for businesses.
Wazuh automatically collects and aggregates security data from systems running Linux, Windows, macOS, Solaris, AIX, and other operating systems in the monitored domain, making it an extremely comprehensive SIEM solution.
But more importantly, Wazuh also analyzes and correlates data in order to detect anomalies and intrusions. This intelligence allows for early detection of threats in different environments.
For example, Wazuh can be used in the office, as well as in cloud environments so remote workers can still reap the benefits of Wazuh. Digital security does not have to be done in a traditional brick-and-mortar environment.
Wazuh software has multi-platform agents that monitor systems, detect threats, and trigger automatic responses as needed. They are particularly focused on rootkits, malware and suspicious anomalies.
These agents are also able to detect and block stealth technologies like hidden files, cloaked process, or unregistered listeners.
Aside from these intrusion detection capabilities, Wazuh’s server also uses a signature-based method. The server analyzes log data to determine points of compromise. It compares them with existing signatures.
This feature allows employees to immediately stop malicious software from being downloaded and installed by their colleagues.
This provides a safety net for workplaces. Employee education on cybersecurity should be the first line of defense, after all.
Wazuh can also pinpoint where network vulnerabilities are. This allows enterprises to find their weakest links and plug up holes before cybercriminals can exploit them first.
Wazuh agents pull in software inventory data from their servers and then send it to them. Here, it’s compared with continuously updated common vulnerabilities and exposure (CVE) databases. As a result, these agents will find and identify any software that’s vulnerable.
In many cases, antivirus software can take care of these vulnerabilities. These programs release security patches on a regular basis.
But in rare cases, antivirus developers won’t find vulnerabilities in time. Or they might not find them at all, which can leave businesses exposed. Wazuh gives businesses an additional set of eyes that can help ensure cybersecurity.
Log Data Analysis
Wazuh not only collects network data and logs from applications, but also secures these files to a central manager who can then use them for rule-based storage and analysis.
This analysis of log data is based on over 3000 different rules that identify anything that has gone wrong, whether it is an outside force or user error. The rules can be used to detect system or application errors as well as policy violations and attempted or successful malicious activities.
In addition, the log data analysis can pinpoint both attempted and successful malicious activities. Network security is best maintained by early detection.
Enterprises can learn from attempted malicious activities and upgrade their cybersecurity accordingly.
And for successful malicious activities, the system can quickly quarantine infected files. Or they can delete them before they can do more damage.
A log data analysis may also reveal policy violations. Whether they’re intentional or unintentional, these violations can be brought to management’s attention. They can then swiftly correct the situation.
File Integrity Monitoring
Wazuh can set up File integrity Monitoring (FIM), which scans selected directories and files periodically to alert users when changes are made. Not only does it keep track of which users create and modify files, but it also tracks which applications are used and when ownership is changed.
Thanks to the level of detail from file integrity monitoring, businesses will be able to know exactly when threats come in. You’ll be able to identify any compromised hosts immediately.
For instance, ransomware is now rampant, but Wazuh can help prevent and detect this threat. Should a hacker attempt phishing, the security monitoring will pick up on the malicious files that have snuck in. It will detect new files created, as well as any original files removed.
Should there be a high number of these instances, the file integrity monitoring will flag it as a possible ransomware attack. This should only be possible if you create custom rules.
Compliance with security regulations is vital to enhance an organization’s security and decrease its vulnerability to attack. But it can be both time-consuming and challenging. Fortunately, Wazuh can assist with it.
Wazuh’s Automated Security Configuration Assessment (SCA) looks for misconfigurations and helps maintain a standard configuration across all monitored endpoints.
In addition, Wazuh agents also scan applications that are known to be vulnerable, unpatched or configured insecurely. This ensures that the most robust cybersecurity barriers are in place at all times.
The regulatory compliance function helps you to comply with regulations and standards. More importantly, it allows businesses to scale and integrate other platforms.
Wazuh generates reports with its web user interface. Multiple dashboards allow users to control all their platforms from one location. Users are immediately alerted if the agents spot anything not in compliance.
Many financial institutions can meet the Payment Card Industry Data Security Standard’s (PCI DSS), because it is so easy to use. This includes payment processing companies, too.
Healthcare professionals can rest assured that they are HIPAA compliant. And for those who deal with European data, they’ll be GDPR-compliant as well.
Incident response is a very useful feature of Wazuh for active threats. The system comes with pre-programmed active responses. This means that the user does not have to create them. Should the system detect active threats, countermeasures jump into action right away.
For example, many hackers use brute-force attacks to guess username and password combinations. Each failed authentication attempt will be noted by Wazuh.
With enough failures, the system will recognize them as part of a brute-force attack. It will stop further attempts at that IP address if it meets a specific criteria (e.g. five unsuccessful login attempts). Wazuh can not only detect brute force attacks but can also close them down.
Users can also use the tool to execute remote commands or system queries. Remotely identifying indicators of compromise (IOCs) can be done.
This allows third parties to run live forensics and incident response tasks. As a result, this opens up opportunities to work with more professionals who can safeguard company data.
Today, many workplaces use the cloud to store files. This allows employees to access them from all over the world, so long as they have an internet connection.
But with this convenience comes a new security concern. Anyone with an internet connection can possibly hack the cloud and gain access to sensitive data.
Wazuh makes use of integration modules that pull security data from cloud providers like Amazon AWS and Microsoft Azure. In addition, it sets rules for a user’s cloud environment to spot potential weaknesses.
It works similarly to the vulnerability detection function. It will alert users to intrusion attempts, system anomalies, and unauthorized user actions.
Wazuh’s containers security features provides cyber threat intelligence to Docker hosts and Kubernetes Nodes. Again, it will find system anomalies, vulnerabilities, and threats.
Users don’t need to establish connections with Docker containers and hosts. The agent will continue to collect and analyze data. It will also provide users with continuous monitoring of running containers.
Wazuh is a Must for Enterprises
Cybercriminals are constantly evolving as the digital landscape changes. It is important to keep up with cybersecurity and invest in intrusion detection technology that can detect when an attack occurs.
Wazuh combines all of these features in a single platform, making it a powerful tool for analysts as well as a real force multiplier for overburdened IT staff.
Wazuh adds context to alerts, analyses and reports, making it easier to make better decisions and assisting in risk and compliance management.
Wazuh is a combination of vulnerability detection, file integrity monitoring and configuration assessment to help enterprises stay one step ahead hackers.
