How Wazuh can improve business digital security
2021 was a year dotted with cyber attacks, with numerous data violations.Not only that, but the ransomics have also become a leading player in the pirate world.
Today more than ever, it is important for companies to strengthen cybersecurity measures. Ils peuvent le faire grâce à plusieurs technologies, telles qu’une plate-forme de sécurité open source telle que Wazuh.
Wazuh is a free and open source security platform that unifies XDR and SIEM capacities, which not only allows companies to detect sophisticated threats, but can also help prevent data violations and leaks.Consequently, this can save companies with expensive solutions which can ultimately lead to their closure.
It is also possible to integrate Wazuh with a number of external services and tools.Some of them are virustotal, Yara, Amazon Macie, Slack and Fortigate Firewall.Consequently, companies can improve their safety against pirates who enter their networks.
What is great with Wazuh is that it is scalable, open source and free.It can compete with many high -end cybersecurity solutions that are available for a lot of money.This can therefore greatly help SMEs on the budgetary plan.

Security analysis
Wazuh automatically collects and aggregates systems safety data running Linux, Windows, MacOS, Solaris, Aix and other operating systems in the supervised field, making it an extremely complete SIEM solution.
But more importantly, Wazuh also analyzes and correlates data in order to detect anomalies and intrusions.This type of intelligence means that there is early detection of threats in various environments.
For example, Wazuh can be used in the office, as well as in cloud environments so that workers remotely can always enjoy the advantages of Wazuh.Improving digital security should not be limited to a physical environment.
Intrusion detection
Wazuh software has multiplatform agents that monitor systems, detect threats and trigger automatic responses if necessary.More specifically, they focus on rootkits and malicious software, as well as on suspicious anomalies.
In addition, these agents can detect stealth technologies such as hidden files, hidden processes and unregistered network headphones.
In addition to these intrusion detection capacities, the wazuh server has a signatures -based approach.He analyzes the data from the collected newspaper and can determine the compromise points by comparing them to known signatures.
This feature can immediately determine and prevent employees from downloading and installing malicious applications.
This gives workplaces a safety net.After all, training of cybersecurity employees should be the first line of defense.
Vulnerability detection
Wazuh can also identify where the vulnerabilities of the network are.This allows companies to find their weakest links and to fill the gaps before cybercriminals can exploit them first.
Wazuh agents will extract software inventory data and send it to their server.Here, it is compared to common vulnerability and exposure databases (CVE) updated permanently.Therefore, these agents will find and identify any vulnerable software.
In many cases, antivirus software can take care of these vulnerabilities.These programs regularly publish security fixes.
But in rare cases, antivirus developers will not find vulnerabilities in time.Or they may not find them at all, which can expose companies.Having wazuh means that companies have an additional look to ensure that their cybersecurity is hermetic.
Journal data analysis
Not only Wazuh collects network data and application newspapers, but it also sends them safely to a central manager for analysis and storage based on rules.
This analysis of newspaper data is based on more than 3000 different rules that identify everything that has gone wrong, whether it is an external force or a user error.For example, the rules in place can detect application or system errors, policy violations, configuration errors, as well as attempts at malicious or successful activity.
In addition, the analysis of the data of the newspaper can identify both the tried and successful malicious activities.Early detection is essential to ensure the safety of networks.
Companies can learn attempts at malicious activities and upgrade their cybersecurity accordingly.
And for successful malicious activities, the system can quickly put infected files in quarantine.Or they can delete them before they can do more damage.
Another thing that the analysis of the newspaper can show is policy violations.Whether intentional or not, these violations can be paid for the management.Then they can take rapid measures to rectify the situation.
File integrity monitoring
WAZUH's (FIM) monitoring function can be configured to periodically analyze selected files or directories and alert the user when changes are detected.Not only does he keep track of users who create and modify files, but it also follows which applications are used and when the property is modified.
Thanks to the level of detail of monitoring the integrity of the files, companies will be able to know exactly when the threats arrive.They will also immediately identify compromise hosts.
For example, ransomware is now rampant, but Wazuh can help you prevent and detect this threat.If a pirate attempts an attempt at baying, safety monitoring will detect the malicious files that have been introduced.It will detect the new files created, as well as all the original deleted files.
If there are a large number of these bodies, monitoring the integrity of the files will point it out as a possible ransomware attack.Note that personalized rules must be created to happen.
Configuration assessment
Security compliance is essential to improve the safety posture of an organization and reduce its attack surface.But it can be both time consuming and difficult.Fortunately, Wazuh can help you.
The automated evaluation of the security configuration (SCA) of Wazuh is looking for configuration errors and helps maintain a standard configuration on all monitored terminals.
In addition, Wazuh agents also analyze the applications known to be vulnerable, not corrected or configured in an unsecured manner.In this way, the strongest cybersecurity walls are in place at any time.
Regulatory conformity
With regard to compliance, the regulatory compliance function also helps users to keep up to date with standards and regulations.Most importantly, it allows companies to evolve and integrate other platforms.
Wazuh generates relationships with its web user interface.There are also several dashboards to allow users to manage all platforms from one place.If the agents note non-compliance, users are instantly alerted.
Its ease of use allows many financial companies to meet the requirements of the data security standard in the payment card industry (PCI DSS).This also includes payment processing companies.
Health professionals can have a peaceful mind knowing that they are in accordance with the Hipaa law.And for those who process European data, they will also comply with the GDPR.
Response to incidents
The response to incidents is a very useful functionality of Wazuh for active threats.There are ready -to -use active responses, which means that the user has nothing to do to configure them.If the system detects active threats, countermeasures immediately enter into action.
For example, many hackers use brute force attacks to guess the combinations username and password.Wazuh will take note of each attempted authentication stranded.
With enough failure, the system will recognize them as part of a brute force attack.Since a certain criterion is met (for example, five unsuccessful connection attempts), he will block this IP address against other attempts.This not only means that Wazuh can detect attacks by brute force, but that it can also stop them.
In addition, users can use it to run remote controls and system requests.They can also remotely identify compromise indicators (IOC).
This allows third parties to perform investigation and response to live incidents.Consequently, this opens up opportunities to work with more professionals capable of protecting business data.
Infonuagic security
Today, many workplaces use the cloud to store files.This allows employees to access it from all over the world, as long as they have an internet connection.
But this convenience is accompanied by a new security problem.Anyone with an internet connection can possibly hack the cloud and access sensitive data.
Wazuh uses integration modules, which extract well -known cloud supplier security data, such as Aws, Microsoft Azure or Google Cloud.In addition, it defines rules for the cloud environment of a user in order to detect potential weaknesses.
It works similarly to the vulnerability detection function.It will alert users of intrusion attempts, system anomalies and unauthorized user actions.
Container safety
The Wazuh container security function provides cyberrenchers for Docker hosts, Kubernetes nodes and containers.Again, it will detect anomalies, vulnerabilities and system threats.
The native integration of the agent means that users do not have to configure connections with their Docker hosts and containers.He will continue to collect and analyze data.It will also provide users in continuous monitoring of containers in progress.
Wazuh is a must for companies
While the digital world continues to evolve, cybercriminals too.Therefore, it is essential to follow cybersecurity measures and invest in high -end intrusion detection.
Wazuh combines all these features in a single platform, making it a powerful tool for analysts as well as a real force multiplier for overwhelmed IT staff.
Compared to other solutions, Wazuh automatically adds a context relevant to alerts and analyzes, allows better decision -making and helps improve compliance and risk management.
When combined with the detection of vulnerabilities, monitoring file integrity and configuration assessment, Wazuh can help businesses keep a step ahead of pirates.
By investing time and resources in this free platform, companies can add more layers to their cybersecurity measures.And in return, they will set up more secure networks for the years to come.
