Security Monitoring (SEM)
Security monitoring, sometimes referred to as “Security Information Monitoring (SIM)” or “Security Event Monitoring (SEM)”, involves the collection and analysis of information to detect suspicious behavior or unauthorized system changes on your network, defining which types of behavior should generate alerts and then take alert-based countermeasures as needed.
Real-time monitoring is one of the keywords in the world of cybersecurity today. The reason? According to all security companies, one of the current problems in cyber-security concerns the ability of companies to promptly detect a system breach: solid grounds for this assumption are the statistics based on the forensic analysis of the attacks suffered in the past years. Most of the IT administrators are often able to detect breaches only weeks or even months after the first attack. During this time frame, hackers have plenty of time to move around the infrastructure of the hakered system and do what they want. In order to stem what is becoming a real emergency, we definitely need to adopt a different approach inspired by real time monitoring.
Security management encompasses all those activities of management, identification, enhancement and risk analysis that can cause damage to property and otherwise (theft, fraud, information leakage) within a company, an organization or grouping of assets and people. Professionals engaged in this activity are called security managers.
Corporate or institutional security is the analysis and implementation of strategies, policies and operational plans aimed at creating innovative perspectives of value for the company or the organization to prevent, respond to and overcome non-competitive events that can affect tangible and intangible resources and human resources. As a result of the implementation of such strategies, you may ensure sufficient competitiveness in the short or medium term.
Why adopting security monitoring is essential?
Whether they are hackers or malware, unwary or disgruntled employees, outdated or vulnerable devices and operating systems, public and mobile cloud computing, or third-party service providers, in the normal course of business most enterprises are generally exposed to security threats of varying severity.
Given the omnipresent and inevitable nature of security risks, rapid response times are essential to keep the system secure. Therefore a continuous and automated security monitoring is crucial for rapid detection of threats and a prompt adoption of effective countermeasures.
In practice, the concept of real time monitoring involves implementing a system capable of monitoring the IT infrastructures to constantly analyze their functioning and promptly detect any anomalies. The main tools for carrying out checks of this kind are SIEM (Security Information and Event Management), which allows you to record all security events within the network, and a SOC (internal or external) that allows you to analyze the recorded logs from the system and investigate any “red flags” that would emerge.
However, control is not limited to applications or services, but also to users. The analysis of user behavior, entrusted to artificial intelligence systems, allows to immediately identify anomalous behaviors (for example, a connection outside the usual hours or from an unusual geographical position) that may represent an indication of threat. Ultimately, this constant monitoring activity allows you also to quickly identify the symptoms of system compromise and, combined with indispensable intelligence, a it will make possible to reduce the time required to detect an attack, respond adequately and, ultimately, protect sensitive company data
