At one time when data security was a concern, it was keeping it secure. But since the introduction and growth of cloud computing, that attitude has evolved. As of today, 60% of corporate data is in clouds, while more potentially sensitive data is transferred from on-premises to off-premises each day. The problem is that increased use of cloud services does not necessarily translate into increased cloud confidence – around 60% of IT and security leaders are not fully confident in their organization’s ability to protect crucial cloud access.
The reality is that whether it’s either on-site or cloud, business data is under constant attack from increasingly sophisticated cyber threats. In the same way there’s a lot at stake: the loss of revenue or customer data being exposed loss of business capabilities, reputational damage, and the legal consequences for failing to adhere to regulatory standards are all real consequence of even the smallest breach. Thus, businesses across all industries need effective methods for quickly identifying and managing threats in every form and across their entire attack surface.
Microsoft Sentinel is designed to fulfill these requirements.
What is Microsoft Sentinel?
Microsoft Sentinel (recently changed to Microsoft Sentinel) is an information security and event management (SIEM) system that is also an orchestration platform for security automated response (SOAR). The Azure SIEM/SOAR solution is an all-encompassing approach to data security offering a bird’s eye view of every part of your company, providing intelligent security analytics for optimal detection of attacks, visibility of threats active hunting, and the ability to respond to threats.
Fully cloud-native and capable adapting to any organization’s ever-changing requirements, Microsoft Sentinel is the culmination of years of data-security experience, applying modern AI capabilities to provide modern organizations with greater speed, intelligence, and intelligence without the need to develop infrastructure in-house or incur maintenance expenses.
What is Microsoft Sentinel Do?
Microsoft Sentinel is a comprehensive approach to protecting your company’s data. This one-stop solution aggregates information from all sources across the entire enterprise which includes users, applications servers, servers, as well as on-premises and cloud-based devices.
In another way, Microsoft Sentinel is a complete security solution that is that is able of performing the following functions:
Collecting Data
Every part of your business produces data. Fully realizing that data is the key to building a strong security position. The Microsoft Sentinel Service collects data from every data source, using the Log Analytics tool to record relevant events and other details for analysis in depth.
Detecting threats
The process of putting your data and information under scrutiny, Microsoft Sentinel applies Microsoft Analytics and continuously-evolving threat information to identify any undetected risks or suspicious activity in the system. This reduces the risk of encountering false positives. If potential threats are identified security teams are promptly alerted and threats are classified and listed for assignment and investigation.
Investigating Threats
Microsoft Sentinel allows you to be proactive and search for suspicious activity and investigating threats through detailed analysis of data correlated across several sources. AI-enhanced capabilities enable you for you to extend threat detection to any business size.
Responding to threats
When your data is under attack Every second counts. Microsoft Sentinel includes automation options and orchestration built-in, to provide immediate ability to detect threats.
What is what are the Elements of Microsoft Sentinel?
Although Microsoft Sentinel is a single, comprehensive security-intelligence solution, it is comprised of several different components. These nine primary elements include:
Analytics
Advanced analytics within Microsoft Sentinel uses the Kust Query Language (KQL) to enable users to design custom alter conditions. Alerts are organized into “incidents” that represent possible dangers to be investigated and resolved and reducing the total amount of alerts that have to be scrutinized to IT security teams.
Cases
Based on analytics that are defined by the user, Microsoft Sentinel collects all relevant evidence from investigations into particular cases. It also contains one or more alerts.
Community
Microsoft Sentinel has a dedicated and vibrant community that is located at the GitHub Microsoft Sentinel community page. This community has vital resources for detections based on various information sources, including security playbooks, hunting queries and many more.
Dashboards
Data visualization is a major element that is a major feature of Microsoft Sentinel; built-in dashboards allow users to easily review the data’s aggregated insights in an eagle.
Data Connectors
As a component of the larger Microsoft ecosystem, Sentinel integrates seamlessly with other Microsoft and Microsoft-partner solutions as well as products. This lets data be shared and ingested across different systems.
Hunting
Microsoft Sentinel uses proactive threat analysis, enhanced by AI and ability to learn from machines in KQL to spot suspicious behavior and enhance its effectiveness over time.
Notebooks
Integrations built-in to Jupyter Notebook provide direct access to library and module for embedded analytics and data analysis, machine learning, and visualization. This expands usability and increases the possibilities of using the data that is stored and collected.
Playbooks
When alerts occur, knowing what steps to take can make the difference. Microsoft Sentinel includes playbooks detailing the exact actions to be performed in response to specific security alerts. Azure Logic Apps increase flexibility and personalization by enabling the users to automatically coordinate specific response tasks 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 based on access rights of the user as well as other.
What Threats are Countered By Microsoft Sentinel?
As a complete, single-stop SIEM/SOAR platform, Microsoft Sentinel is effective in detecting, investigating as well as responding to whole range of threat actors and cyber-attacks. However, even though Sentinel offers reliable protection against botnets, phishing attacks malware, and more and more, it is more important in combating some of the most recent and most ingenious threats.
Microsoft Sentinel is a viable solution for:
Credential Stuffing
Security researchers continue to admonish users to vary their passwords. But, many are still using the same passwords to log into various accounts and devices and are particularly at risk of bot-driven credential attacks aimed at the theft of login credentials. Sentinel detects the warning signs of credential stuffing as well as other identity attacks, locking out the threat actors and alerting the response teams.
Remote Work Attacks
With the new hybrid-office and remote-work employee expectations following the COVID-19 virus, important corporate data is not only accessible to businesses’ networks and devices. Microsoft Sentinel extends vital security capabilities to remote locations and protects data in areas that are most vulnerable.
Double Extortion Ransomware
One of the biggest threats to data security is double extortion ransomware attack in which hackers gain control over the systems of an organization and demand payment in exchange for giving access back to the legitimate owners. Microsoft Sentinel uses a correlation engine built on machine learning algorithms that are scalable to determine whether security alerts have a connection to the possibility of ransomware.
