Once upon a time when data security was a concern, it was keeping it safe. With the advent and the subsequent growth of cloud computing, this attitude has changed. Nowadays, up to 60% of corporate data is in the cloud and more potentially sensitive information makes the journey from on- to off-premises each day. The problem is that increased use of cloud services does not mean greater cloud trust – approximately 60 percent of IT and security managers aren’t convinced of their organization’s capability to safeguard crucial cloud access.
The sad truth is that whether stored on site or in the cloud, data of businesses is continuously under attack from increasingly sophisticated cyber threats. In the same way there’s a lot at stake: Loss of revenue or customer data being exposed and business capabilities being diminished, reputational damage, and penalties for failure to meet regulatory standards are all very real implications for even the most minor of breaches. As such, organizations in all industries need effective solutions to detect and addressing threat anomalies in every form and across their entire attack surfaces.
The Microsoft Sentinel Service is designed to fulfill these requirements.
What is Microsoft Sentinel?
Microsoft Sentinel (recently named Microsoft Sentinel) is an event and security information management (SIEM) system which also functions as an instrument for security orchestration (SOAR), automation, and orchestration (SOAR). The Azure SIEM/SOAR solution is an all-encompassing approach to data security offering a bird’s eye perspective of all areas of your business. It provides sophisticated security analytics to ensure optimal security, detection of threats, proactive hunting, and threat response.
Cloud-based and capable of scaling to meet any company’s ever-changing requirements, Microsoft Sentinel is the culmination of decades worth of security experience in the field, using modern AI capabilities to provide modern businesses with faster, smarter large-scale intelligence without the need for internal infrastructure development or maintenance expenses.
What is Microsoft Sentinel Do?
Microsoft Sentinel is a comprehensive strategy to safeguard the data of your business. This single solution aggregates data from every source across the enterprise that includes applications, users servers, on-premises and cloud-based devices.
In other words, Microsoft Sentinel is a fully integrated security solution, capable of the following functions:
Collecting Data
Each part of your company produces data, and fully understanding that data is central to building a strong security position. Microsoft Sentinel collects data from every source of data and employs its Log Analytics tool for storing relevant events and other information for analysis in depth.
Detecting threats
In putting your data under a microscope, Microsoft Sentinel applies Microsoft Analytics backed by constantly-evolving threat intelligence to spot any unidentified threats or suspicious activity within the system. This reduces the likelihood of getting false positives. If potential threats are identified, security teams are immediately alerted and threats are classified to be assigned an investigation.
Investigating Threats
Microsoft Sentinel allows you to take on the offensive looking for suspicious actions and investigating threats through detailed analysis of data that is correlated with multiple sources. AI-enhanced features make it possible to expand threat analysis to any size business.
Responding to threats
If your data is under attack every second is important. Microsoft Sentinel includes automation options and built-in orchestration, for immediate capability to respond to threats.
What is some of the Elements of Microsoft Sentinel?
Although Microsoft Sentinel is a single, comprehensive security-intelligence solution, it is comprised of several different components. These nine fundamental elements comprise:
Analytics
Advanced analysis in Microsoft Sentinel uses the Kust Query Language (KQL) to let users create custom-designed alter conditions. Alerts are organized into “incidents” indicating possible threats that require investigation and resolution, reducing the overall amount of alerts required to be reviewed in the hands of IT security experts.
Cases
Based on user-defined analytics, Microsoft Sentinel collects all relevant evidence from investigations into particular cases. It also contains several alerts.
Community
Microsoft Sentinel has a dedicated and vibrant community that is located on the GitHub Microsoft Sentinel community page. The community provides essential resources for detections that are based on a wide range of data sources, in addition to security playbooks, hunting queries, and more.
Dashboards
Data visualization is a major aspect in Microsoft Sentinel; built-in dashboards allow users to easily review information from a variety of data sources in one glance.
Data Connectors
As part of the overall Microsoft ecosystem, Sentinel integrates seamlessly with other Microsoft and Microsoft-partner products and products. This lets data be shared and ingested across multiple systems.
Hunting
Microsoft Sentinel uses proactive threat analysis that is enhanced with AI and the machines-learning abilities of KQL to spot suspicious behavior and enhance its effectiveness over time.
Notebooks
Built-in integrations with Jupyter Notebook allow direct access to the most useful libraries and modules for embedded analytics and data analysis machine learning, data analysis, and visualization. This increases the accessibility and the applications for the data that is stored and collected.
Playbooks
When alerts happen knowing the best steps to take could make all the difference. Microsoft Sentinel includes playbooks detailing precisely what actions should be taken in response to specific security alerts. Azure Logic Apps increase flexibility and customization by allowing the users to automatically manage the appropriate response processes and workflows.
Workspace
Microsoft Sentinel groups data and configuration information from different sources into containers called Log Analytics Workspaces. These Workspaces contain data storage location information and data isolation in accordance with access rights of the user and more.
What kinds of threats can be thwarted By Microsoft Sentinel?
As a comprehensive, all-in-one SIEM/SOAR platform, Microsoft Sentinel is effective in identifying, investigating, and responding full range of threat actors and cyber-attacks. However, even though Sentinel offers reliable protection against botnets, phishing, malware, and so on It could also be more vital in countering some of the latest and most inventive threats.
Microsoft Sentinel is a viable solution for:
Credential Stuffing
Security specialists continue caution users to vary their passwords. That said, many still use the same passwords to log into various devices and accounts, and are particularly at risk of bot-driven credentials attacks aimed at getting login credentials. Sentinel identifies the tell-tale signs of credential stuffing as well as other identity theft, and blocks out threat actors and alerting response teams.
Remote Work Attacks
With new expectations for hybrid-office and remote work, employee expectations following the COVID-19 virus, important business data is no longer only available to networks for business and devices. Microsoft Sentinel extends vital security capabilities to remote work sites safeguarding data wherever it’s most vulnerable.
Double Extortion Ransomware
One of the biggest risks to data security is the double extortion attack, where cybercriminals gain control of an organization’s systems and request payment in exchange for giving access back to the legitimate owners. Microsoft Sentinel uses a correlation engine that relies on machine learning algorithms that are scalable to determine if security alerts are related to ransomware-related activity.
