SIEM | Security Information and Event Management
Security Information and Event Management (SIEM) combines state of the art tools and real time services dedicated to detect anomalous incidents in networks and all systems of a company. Nexsus offers SIEM as a part of its SOC proposition within the ambit of Managed Security Services.
What is Security Information and Event Management?
The IT or ICT infrastructure of any contemporary company usually has at least one network, multiple systems and devices, a few applications, and some databases. The servers for databases, emails, and other purposes may or may not be within the premises. For expected functioning of every department and uninterrupted operations, the network facilitates innumerable communications, the systems and devices interact with one another within and beyond the organization, the applications are accessed by authorized users, and the servers provide the foundation for all such activities.
Every access is logged. It could be a log-in to a system, an email, or an application. All data transfers are also documented. Any such activity is an event. Over a period of time, the logs tend to develop a pattern. Studying the entire security information paradigm enables cyber security specialists at Nexsus to understand the types of authorized accesses to a network, within the technological framework of the company, and the various uses of all its technical resources. This understanding enables our experts to flag unauthorized access, suspicious activity, or malicious event.

Benefits of Nexsus SIEM
SIEM is one of the many inseparable components of SOC as a service. Managed Security Services cannot be holistic or comprehensive without efficient and effective security information and event management. While the larger objective is a failsafe cyber security apparatus, SIEM delivers the following benefits as a standalone tactic.
- Assessment of Routine Incidents & Events
Nexsus log aggregation, analysis, and forensics lead to a complete assessment of routine incidents and events. This assessment is crucial if anomalies are to be detected. Our SIEM solution performs all assessments and then uses the understanding to detect every anomalous and suspicious incident or event.
- Assimilation of Intelligence Inputs & Analyses
The assessment of all routine incidents and events, including the standard and expected deviations in many accesses and activities, leads the Nexsus Cyber Solution team to attain intelligence inputs. Such intelligence gathering mechanisms are critical to understand the nature and scope of cyber threats for a specific organization. Analyzing these intelligence inputs and reports allows our cyber security experts to form a strategy for SIEM.
- Prevention of Unauthorized Network Connection
Nexsus SIEM prevents every unauthorized network connection. Since all routine, standard and expected connections are logged and assessed already, unauthorized activities can be detected and prevented. Real time monitoring of the entire cyber security network further strengthens this preventive action.
- Blocking of Illegal Accesses & Anomalous Activities
SIEM takes into account all potential points of access, from emails to database interactions, communications within a network to every exchange of information. All potentially suspicious accesses, anomalous activities and outright threats are detected and blocked immediately.
- Detection of Suspicious Events & Instant Notifications
SIEM precedes deployment of countermeasures. The latter is facilitated by instant notifications following the detection of suspicious events. The countermeasures could range from shutting down a point of access to blocking flagged internet protocol addresses, among several other tactics.
- Adherence to Compliance Management & Reporting
There are several compliance standards that demand an effective SIEM strategy. One of the most common and important example of such standards is PCI DSS. Payment Card Industry Data Security Standard is imperative for every company that deals with financial transactions, online or offline, especially using credit and debit cards. PCI DSS compliance is aimed at preventing data theft, misuse of personally identifiable information, and different types of financial fraud.
Nexsus SIEM ensures flawless compliance management and reporting. SOC as a service including SIEM is a quintessential requirement for every company that relies on an IT or ICT infrastructure. Nexsus Cyber Solution offers bespoke SOC as a service including customized Security Information and Event Management.
