As part of an organization’s security against cyberattacks and unauthorised access, a SOC is essential. Security operations professionals have a wide range of responsibilities, including asset management, incident response, and more. In order to make an informed choice, it is important to learn about the various security operations available. The following definitions and definition terms may help you better understand SOC.

Asset tracing and administration
As part of a security operation, discovering and managing assets is critical. Discovering installed and retired assets, along with vulnerabilities and active threats, is made easier with a powerful asset discovery and management tool. It also identifies software and hardware assets that require optimization or repair. This data can be used to estimate the cost of hardware and software, as well as to suggest further software or hardware that may be needed. To avoid data breaches and lower your IT expenses, you should implement a systematic approach to asset discovery and management.
You can automate the inventory process by discovering and managing all internet-facing assets. With this, you can keep your eye on the ball when it comes to finding threats and vulnerabilities early. When it comes to automating compliance and auditing procedures, asset management software can be an invaluable tool. Assets can be discovered automatically to ensure that they are in compliance with both internal and external rules. You’ll be able to see your entire attack surface, and you’ll know when it’s time to upgrade or repair.
SOCs can reduce costs by eliminating the need for various security systems. Management and documentation of the center’s operations are possible. The method for discovering and managing assets depends on the organization’s functions and security requirements. ‘ A multi-tiered approach to security underpins SOC initiatives. As a result, your company must choose a solution that blends multiple layers of protection.
Any unlicensed software can be found and managed with the help of an asset discovery and management solution. An unlicensed use of software might result in sanctions. You can use an asset discovery tool to look for problems with virtual and physical assets in both on-premises and cloud-based settings. Any cloud environment or on-premises network may rapidly be assessed for its vulnerability using asset discovery.
Network activity logs are collected and analysed by security analysts as part of the SOC’s job in order to identify potential risks and carry out remediation if an event happens. SIEMs are used by certain SOCs to combine and correlate data flows from many sources, including firewalls and operating systems. As important as a SIEM is to security operations, its capabilities go far beyond simply responding to issues. An company can be protected against potential risks thanks to this software’s ability to identify them.
Response to a crisis
To prevent and respond to cybersecurity issues, incident response is one of the most important functions of a security operations centre (SOC). SOCs are responsible for both preparing for and responding to incidents, as well as for coordinating the subsequent recovery and mitigation actions. The structure of authority and responsibility, as well as particular measures to take in each scenario, are all outlined in incident response plans. In order to ensure that everyone is on the same page, top-performing SOCs periodically conduct tabletop exercises with the rest of their business.
A natural system failure, such as a traffic overload or a hardware repair, might lead to a security issue. If a SOC as a service is part of an overall incident detection programme, it will be able to respond to these situations more quickly. Many companies outsource their security operations centres (SOCs) because they can’t support them in-house. However, even though a SOC’s responsibilities may be limited, it is crucial to ensure it is performing to its full ability.
In spite of its importance, incident response in the SOC is a reactive activity. It has a significant impact on the amount of time it takes to recognise and correct an occurrence. A network’s profile and log retention policies are used by incident response teams to identify suspicious activities. After spotting an attack, they need to prioritise and deal with it. Post-event activities include assessing the performance of the incident response team and making any necessary adjustments.
The core of an efficient SOC approach is threat management, which involves gathering and analysing data to look for signs of malicious behaviour.
Data pertinent to security is often gathered by these teams from sources such as firewalls, threat intel, intrusion prevention systems, probes, and SIEM systems. In addition to that, they provide warnings based on data that is abnormal. In addition, a SOC plan will include asset identification and management, which entails checking that every asset is patched, functioning, and up to date.
The handling of incidents is an essential part of a SOC. The security operations teams get a large number of notifications on a daily basis, which they then investigate to establish whether or not an event actually occurred. Once an issue has been identified, analysts will assign priorities to the alerts and collaborate with a variety of stakeholders to identify the appropriate course of action. Incidents related to security frequently require intricate processes and equipment. The SOC commander is in charge of supervising the SOC team and figuring out the most effective way to respond to the crisis.
Logs of network activity are gathered and examined by the SOC in order to create a “normal” level of network activity as a baseline. These logs provide information that can help uncover potential hazards and provide guidance for repair after an event has occurred. The vast majority of SOCs make use of SIEM software in order to aggregate data and correlate data flows coming from network devices, endpoints, and apps. SOCs are able to assess which threats are the most widespread and which technologies are best suited to manage them by monitoring the behavior that occurs on networks.
