A Security Operation Centre or SOC is a core function monitoring and improving the security posture of an organization. It collects data from all components of an organization including devices, stored data and networks. It is a hub for detection, prevention, analysis and response to security incidents.
Best Key Tools For Setting Up A SOC Team
A SOC team needs to be able to perform certain functions on the data generated within an organization’s IT infrastructure. With these capabilities the team can maintain the security and qualify for security compliance. There are some tools which are the key to maintaining the security of a network. Technologies that drive these tools are also essential.
Let us look at four tools which are most important for running a functional network with an operational SOC team.
Log Collection And Management Tool
Logs of data form the basis of many security analyses in a network. All the information generated by all the connected devices in a network are logged in various lists. Anomalies in this data are very useful for security assessments. But going through these logs is impossible unless the process is automated. Tools that help in collecting, parsing and analyzing logs are log collection and management tools.
Security Information And Event Management (SIEM)
Logs collected from various devices in a network may have heterogeneity. A Security Information And Event Management Tool collates this data. It then analyzes the data and raises alarms if attack patterns are detected. The Security Operational center team can decipher the graphical reports generated and gain insights on the attack. They can also retroactively find the root causes of security incidents by meticulous analysis of the logs after a security incident using this tool.
The processes and technologies used in a system often have vulnerabilities which remain undetected for long periods. Cybercriminals can use these vulnerabilities to gain access to a secure system. So a fundamental part of the work of the SOC team is to regularly monitor an organization’s network to find and address vulnerabilities.
Endpoint Detection And Response (EDR)
Endpoint Detection and Response tools are mainly focussed on aiding the SOC team in identifying threats that are directed at end users or hosts of the network. Its responsibilities are to detect any security threats to end users and containing the threat at the end point. They do this through continuous data collection and monitoring at the end points. Besides detection and containment the EDR tool alerts the SOC team and tries to remedy the threat by further investigation.
Best Technologies For SOC
Let us look at three technologies that are responsible for driving key features of all these tools mentioned above.
User And Entity Behavior Analytics (UEBA)
This technology is used in tools which monitor logs to determine a baseline for comparison. Determining the baseline for log data of all the components of an organization is the first step to flagging deviations from the baseline as anomalous. This technology is powered by machine learning. So these tools get better and better at spotting potential threats the longer they run and the more data they process. Based on the extent of deviation a risk score is attached which helps the SOC team to prioritize their action.
Cyber Threat Hunting
Cyber threat hunting is a technology which is used in tools for proactive detection of threats in a network. Instead of looking for anomalous patterns and then trying to infer the source of the security incident, this technology takes a different approach. It works by forming hypothesis on the existence of a potential threat in the network. Then patterns in the data are predicted which would be observed if such a threat existed. Then the data logs is scanned and monitored for such predicted patterns.
Threat intelligence powers all the threat detection tools. It is a sharing of information between different organizations to build a consolidated evidence-based pool of data on threats that have occurred and might occur again. Not only can the SOC be able to detect new threats and be aware of ways and means to deal with them, threat intelligence allows the SOC to identify threat actors. Whenever an identified threat actor interacts with a network, the SOC can be immediately alerted. The team can act to isolate the actor or remedy their actions as they know their methods and motivations.
Having the right tools and technologies is important for meeting security compliance and adhering to industry standards.
