Security operations center as service (SOCaaS) is a cloud-based subscription model that allows security-focused threat detection and response that provides top-of-the-line SOC solutions and tools to assist in filling the gaps of the security team in place.
What Cyber-threats are monitored by SOCaaS?
Similar to a traditional on-premises SOC, SOC as a Service includes 24/7 monitoring and detection of threats, prevention as well as analysis of the attack surfaces, including web traffic corporate networks, desktops servers, endpoint devices applications, databases, databases cloud infrastructure, firewalls and intrusion prevention and Security Information and Event Management (SIEM) systems.
Cyberthreats can be classified as ransomware, denial of service (DoS) distributed denial of services (DDoS), malware such as smishing, phishing, insider threats, theft of credential Zero days, and many more.
What are the reasons why Organizations require Managed Services for Security Operations?
In their study report, SOC Modernization as well as the role in the Role of XDR, Enterprise Strategy Group discovered that over half (55 percent) would like security services so that they can concentrate security personnel on security-related strategic initiatives. Some believe that managed service providers can do things that they cannot do for their own organization and 52% of them believing that managed service providers will offer superior security operations than their company can. 49% say a managed service provider could enhance their SOC team and 42% admitting that their company doesn’t have the right skills to handle security operations.
What are the benefits of SOC as an Service (SOCaaS)?
outsourcing security operations and information security management can bring a variety of advantages, including the following:
Cost reductions
More efficient detection and faster remediation that helps to streamline security incidents
Access to the most advanced security solutions
The burden of internal SecOps teams
Continuous monitoring
Accelerating detection and response time to provide high-confidence alerts while reducing fatigue from alerts.
Reducing turnover and reducing analyst burnout; eliminating routine tasks
Simpler and less complex
Lower cyber risk
Improved business scalability and agility
However, problems arising from older SOC environments could include:
Insufficient visibility and lack of lack of context
Complexity of investigations has increased
Incompatibility of systems
Insufficient automation and lack of orchestration
Inability to gather and process information on threat intelligence.
Alert fatigue/noise coming from the low-fidelity, high-volume alerts of security controls
Other advantages of SOCaaS are as follows:
Continuous Protection
Security analysts can track alarms, events as well as indicators of compromise (IoCs). Combine high-fidelity threat intelligence with relevant threat and impact reports. Analyze the results of analysis and threat detection across all data sources to create high-quality leads for threat hunting.
Speedier response times
Rapider response times can help reduce dwell time and increase the mean time to investigate (MTTI) as well as mean time to correct (MTTR).
Prevention and Threat Prevention as well as Threat Hunting
SOCaaS lets teams proactively look at environments for threats techniques, procedures and tactics (TTPs) to identify new vulnerabilities that could be present within your infrastructure.
Security Expertise and coverage
Although SOCs are available in a variety of forms and can include the responsibilities and roles of the role of a SOC leader, incident responder and a Tier 3 security analyst(s). Other specialized roles could include security engineers and vulnerability managers, as well as security analysts, forensic investigators as well as compliance auditors.
Conformity to Compliance and Regulation Mandates
The most important SOC surveillance capabilities play essential to ensuring compliance for businesses, particularly in compliance with regulations that require specific security monitoring capabilities and processes like GDPR and CCPA.
Industries like healthcare and financial services have their own set of regulations to help them take care of risk and stay on top of regulatory changes. They are HIPAA, FINRA and PCI to protect the integrity of personal data and information from unauthorized access.
Improve Security Teams
In addition to investing in security solutions and tools, the most crucial element in any successful SOC remains the human factor.
Machine learning and automation can certainly improve the overall results such as response times, accuracy and remediation, particularly for repetitive, low-level tasks recruiting, training and keeping security professionals, such as security analysts, engineers and architects, must be incorporated into any SOC transformation plan.
Things to consider when designing SOCs SOC
There are a variety of ways to creating and running an SOC. In their research paper Security Operations Center: A Systematic Study and Open Challenges, Manfred Vielberth, Fabian Boh Ines Fichtinger, Manfred Vielberth and Gunther Pernul discuss the factors that affect SOC operating models as well as the various aspects that could be considered when deciding to establish one.
Strategy of the company: The overall business and IT strategy must be considered to determine which operating mode is the most appropriate. A SOC strategy must be formulated prior to deciding on the appropriate operating mode.
Industries: The industry sector within which a business is primarily operating greatly influences the nature of the SOC needed.
Size: The size of a business can also influence the choice since a smaller business might not be able to establish and manage an SOC by itself or may not require an incredibly defined SOC.
Cost: The cost of implementing and managing the SOC should be compared to the cost of outsourcing the security functions. In the beginning, an internal SOC could be more costly however, it could prove to be more economical in the long in the long run. Costs associated with finding, hiring and training SOC personnel are a major aspect, particularly since they could increase due to the increasing shortage of skilled workers and demand in the market.
Time It can take a significant amount of time to establish an SOC. Thus, aligning with the organizational plan and timelines is essential. In addition, the time it takes to establish a SOC must be compared with the time required to outsource it.
Regulations Based on the sector, various regulations should be taken into consideration. Certain regulations may require the use operations of an SOC while others may prohibit outsourcing SOC operations completely or, at a minimum, to certain providers that are not in compliance with the specific rules.
Privacy: Privacy is also under the regulation of privacy and is a requirement when handling personal information.
Accessibility: The requirements for availability should be taken into consideration. In the majority of cases it is important to have an SOC operating 24/7, all year round.
Support for management: The support of management is crucial when establishing a dedicated SOC. If the management team isn’t engaged, and the benefits of an SOC aren’t communicated to the upper management, the team may not receive the necessary resources.
Integration: In an internal SOC must be incorporated to other departments in IT, while in an external SOC the provider has to be connected to access all the information needed.
Concerns about data loss the SOC is typically an important place in which a large amount of data that is sensitive gets processed. Internal SOCs must be well secured, whereas the external SOC requires a reliable service provider who can guarantee that the data is protected from intellectual property theft and accidental loss.
Expertise: It requires the time as well as money develop knowledge. The necessary skills required to run an SOC aren’t easily found. The recruitment and retention of staff is an essential aspect for internal SOCs. But, the required skills are already available for outside SOC providers. Particularly in the case of SOCs, having a view into other companies could give SOC providers an advantage in knowledge. But, businesses must be aware that outsourcing can reduce the knowledge in-house.
What is the reason an Managed SOC is important
Similar to hybrid and on-premises SOCs Managed SOCs are available in a variety of types. Similar to their counterparts, they are able to monitor an organization’s security landscape, which includes their IT networks, devices, applications and the endpoints (attack surface) and their data for known as well as emerging vulnerabilities as well as risks and threats.
Managed SOC services are typically available in two types:
Managed Security Service Providers (MSSPs) which manage SOCs on the cloud and employ automated procedures.
managed Detection and Respond (MDR) which relies more heavily on human involvement that goes beyond basic prevention in order to allow proactive and advanced tasks like the hunt for threats.
Selecting a managed SOC option can ease the burden of maintaining and managing an internal SOC particularly for smaller to midsize companies.
It’s the same for hiring security professionals who can create and manage an SOC that is able to meet the ever-growing IT security standards and requirements. Employing external security experts allows companies to instantly increase their security coverage and improve their security by having access to research databases and threat monitoring that can lead to an increase in return of investment (ROI) than a self-built SOC.
As threat actors embrace their own versions of digital transformation and leveraging the benefits of automation, businesses require security systems that are able to keep up with. Managed security companies can provide continuous coverage and a guarantee of service through Service level agreements (SLAs) which define the scope and duration of services, which includes software updates and patches when they are released or countermeasures against new threats are in place to implement.
The challenges of managing a SOC
While outsourcing security operations can have many advantages, there are there are some limitations and challenges and that’s why it’s important to do your due diligence when you compare solutions, services and SLAs.
Onboarding
Managed SOC providers usually rely upon their security infrastructure. Therefore, their solutions need to be set up and implemented in the customer’s environment prior to the service provider can begin offering services. The transition during the onboarding process could be lengthy and could result in exposure to risk during this period.
Sharing of critical Data
A SOC-as-a-service provider for an organization needs access to gain insights into the network of an organization to detect and address possible threats. In order to achieve this, an organization has to provide large quantities of sensitive information and intelligence towards its provider. However, the release of control over potentially sensitive data can create a risk for security of data as well as risk control more difficult and expose vulnerabilities in this stage.
Data storage outside the Organization
Storing sensitive threat information and analysis outside of the SOC could lead to leaks of data and loss if the SOC’s cybersecurity security is compromised or you decide to leave your service providers. Although you are able to keep track of alerts to threats within your own organization, the majority of data is processed outside of the boundaries, which limit the ability to save and analyze the vast amount of information about threats that have been detected and data breaches that could occur.
The cost of log delivery
SOC-as-a service providers typically operate their cybersecurity solutions on site by utilizing data feeds and network taps that they receive from their customers network. Log files, along with other alert data are created and stored on the provider’s systems and network. Accessing all log data through an SOC provider that is managed SOC provider could be costly for a business.
There is no dedicated IT Security Team
The role, responsibilities and the scope may differ among organizations and can result in a gap if using a one-size-fits all approach instead of. creating a team that is knowledgeable about the specific environment and unique infrastructure of every client. External SOC team might not provide customized services because certain services may be shared between several customers, which could adversely impact efficiency.
Insufficient knowledge of the organization’s Particular Business
In the course of serving many clients and distributing SOC resources Managed SOC providers could miss weaknesses in the environment and not fully comprehending an company’s procedures and processes to safeguard them appropriately.
Regulation and Compliance Aspects
Regulations are rapidly becoming more complicated and companies must implement security measures and procedures to ensure and prove compliance. Although a managed SOC provider might provide support to ensure compliance with regulations however, the use of an outside provider can complicate compliance requirements, and require confidence in a service provider to meet the compliance requirements.
There are limited options to customize services.
External SOC does not offer full customisation of services because they are shared between several clients. The lack of customization options could cause a decrease in efficiency among departments within the company and in the inability to effectively secure certain networks, endpoints and other components that comprise the security system.
Overall, having a dedicated SOC which provides companies with numerous benefits, such as continuous monitoring of networks, centralized visibility and a reduction in cybersecurity costs and improved collaboration, you aren’t going to be disappointed. Cybercriminals never stop, and neither should you.
