Security threats are constantly increasing and are not only coming from external sources. An employee could accidentally misconfigure security settings and leave data vulnerable to attack. If you have come this far, it is because you are interested in knowing what it is or in knowing the advantages of implementing an SIEM system in your company. You are in the right place. Throughout the post we will try to answer the questions that may arise about this technology.
What is a SIEM system?
It is born from the combination of SEM, Security Event Management, and SIM, Security Information Management. This union gives rise to Security Information and Event Management.
On the one hand, SEM centralises monitoring, allowing an almost real-time analysis of what is happening in safety management. In addition, it detects abnormal patterns of accessibility and warns of security-related problems.
On the other hand, SIM takes this data to a next phase that includes the storage, analysis and reporting of the results.
What is its purpose?
Thanks to data standardisation and threat prioritisation, SIEM is able to detect potential security threats. To this end, it carries out a centralised analysis of security data, obtained from different systems, such as anti-virus, firewalls and intrusion prevention solutions.
What are its advantages?
IT organisations have incorporated various systems to protect themselves from intrusions and a host of different threats. However, these protection systems generate so much information to monitor, that IT teams are faced with the problem of having to interpret it in its entirety in order to recognise real problems.
The often understaffed IT security teams are faced with an unmanageable volume of data, which makes this measure unusable, as it cannot be quickly analysed and filtered.
Through an SIEM, IT professionals have an effective method for automating their processes and centralising security management, helping to simplify the difficult task of protecting sensitive information. Therefore, one of the main advantages of implementing an SIEM system in your company is to provide your experts with the difference between a low-risk threat and one that can be decisive for your business.
What is it capable of detecting?
SIEM is used to detect any number of security threats:
- Presence of ransomware
- Unauthorised access to data
- Failed log-in attempts that do not match standard log-in problems
- Even unusual peaks in bandwidth
Whether these threats come from external or internal sources, the software is capable of sending a prioritized alert that will notify your team of the potential problem for immediate investigation.
As security threats evolve, SIEM solutions become a critical component in providing organisations with a secure environment for their data. Therefore, SIEM is one of the most powerful technologies in computer security, allowing computer threats to be detected and neutralised before they occur.
It is not necessary to have a large company to implement this technology, there are alternatives adapted to each size and to the needs of each one. Each company is unique and for an SIEM solution to be as effective as possible hundreds of variables must be taken into account. That is why you should hire a professional and experienced service.
