Security Information and Event Management (SIEM) helps organizations in collecting, correlating, and analyzing log data from a wide range of systems connected to their IT infrastructure. Based on the results, a SIEM solution assists an organization in detecting threats and suspicious activity on their IT infrastructure. If you are already using a SIEM platform such as Logsign, you would know the importance of SIEM reports.
Whether you are a CIO or chief executive of your company, the headlines of cybersecurity threats and attacks might be worrisome for you. There is always a question about how to ensure the cybersecurity of the organization to avoid financial, compliance and reputational risks. Today, to deal with ever-growing, fast, and sophisticated cybersecurity threats and attacks, enterprises either find the correct MSSP (Managed Security Service Provider) or build an efficient SOC (Security Operation Center). In either case, the role of Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) are indispensable.
In this article, we will detail how organizations choose either MSSP or build SOC and how SIEM and SOAR solutions play a crucial role in the MSSP and SOC security solutions.
Dashboards are an integral part of a SIEM solution as they help you in visualizing the security of your organization’s technical infrastructure in real-time. In our last article, we discussed in detail about the pre-configured dashboards on Logsign SIEM and the information they present for your security team. In this article, we explore how you can customize a dashboard, add widgets, manage dashboard categories, arrange dashboards and categories, and much more.
Installation: At this stage, SOC analysts are advised to deploy a Security Information and Event Management (SIEM) and Host-Based Intrusion Detection System (HIDS) to detect attacks. To deny an attack, Cyber Kill Chain recommends using Two-Factor authentication, strong password, and privilege separation as well as disrupting attack using data execution prevention. If the attackers successfully penetrate corporate critical IT infrastructure, SOC teams must contain them in a timely fashion to mitigate damages. To this end, Cyber Kill Chain recommends employing Inter-Zone Network Intrusion Detection System, App-aware firewall, and trust zones.
If you have been using a SIEM tool for quite a time, you will know that it can turn out to be a powerful security tool, if appropriately deployed. In your organization’s network, network devices such as IDS/IPS, firewalls, and routers generate a plethora of log data. Like these devices, there are many sources of data for a SIEM solution. The first barrier a SIEM encounters is normalizing the log data before it can detect and alert your team.
If your SIEM solution is configured correctly, it will filter through irrelevant log data to allow your security team to focus on essential and high-risk alerts. Correlation rules play a crucial role in the configuration of a SIEM platform. In this article, we explore what correlation rules are and how you can create your organization-specific correlation rules on Logsign SIEM.
