As cybersecurity threats increase in sophistication and frequency, the demand for skilled Security Operations Center (SOC) analysts continues to rise. In tandem with defensive strategies and advanced security software, SOC analysts fill a critical role in keeping enterprises safe from attacks.

They are responsible for identifying and mitigating oncoming threats, protecting sensitive information, and ensuring the overall security of an organizations digital assets. Demand for skilled SOC analysts climbs so aspiring defenders need to ensure they have the technical knowledge, analytical skills, and critical thinking abilities required for the job.

This is part two of a three-part blog post series covering the top tips and skills that aspiring analysts will need to master as they begin their journey toward success in the SOC analysis field. In this second post, learn about the top four topics significant to building an understanding of security platforms and tools needed in SOC analysis. Read Part One of the blog series here.

Understanding how cloud computing works and its security risks are becoming increasingly important. Learn cloud concepts and best practices for Incident Response.

In todays digital world, businesses of all sizes rely heavily on technology to operate efficiently. Effective SOC analysts strive for a deep understanding of the latest technologies and tools used in cybersecurity. One area that is becoming increasingly important is cloud computing.

Cloud computing refers to the delivery of computing services over the internet. Instead of hosting software applications and data on local servers or personal devices, users can access these resources remotely over the internet. Cloud computing services can include infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). Essential cloud concepts for SOC analysts include cloud service models, deployment models, security controls, compliance frameworks, and incident response.

There are many benefits to using cloud computing, such as cost savings, scalability, and flexibility. However, potential risks also need to be considered, such as data security and compliance. As a SOC analyst, it is important to understand cloud computing basics to monitor and respond to security incidents effectively.

Cloud computing has fundamentally changed how IT infrastructure is designed, implemented, and secured. With the adoption of cloud services, traditional security measures such as firewalls and intrusion detection systems are no longer sufficient to protect against modern cyber threats. SOC analysts must now be able to monitor and analyze data from cloud environments and traditional on-premises systems.

One challenge in cloud computing is the shared responsibility model. Cloud providers are responsible for the security of the underlying infrastructure, while the customer is responsible for securing their own data and applications. This means that SOC analysts should understand the cloud providers and the customers security controls to detect and respond to security incidents effectively.

Active Directory (AD) is the backbone of most organizations identity and access management systems. A good SOC analyst will thoroughly understand AD concepts like domains, users, groups, and permissions.

Active Directory (AD) is a centralized database that stores information about users, groups, computers, and other resources. Its the backbone of most organizations identity and access management systems and is critical in securing access to sensitive data. Active Directory naturally presents an attractive target for attackers.

To effectively monitor and secure AD, SOC analysts must understand its key concepts, including domains, users, groups, and permissions. Domains are logical groupings of computers and other resources managed as a single unit. Users are individual accounts that are granted access to resources within the domain. Groups are collections of users or computers that are assigned common permissions, and permissions define what actions users can perform on specific resources.

SOC analysts must be able to effectively monitor and manage AD to identify and respond to security incidents. They should thoroughly understand AD security best practices, such as implementing strong password policies, restricting administrative access, and regularly auditing AD activity.

They should also be familiar with AD security tools, such as Microsofts Active Directory Users and Computers (ADUC) console, which allows them to manage users, groups, and other AD objects. Another tool, Active Directory Domain Services (ADDS), is used to manage domain controllers and replication. SOC analysts use AD to perform the following functions:

Writing filters that are used to hunt or detect threats is a foundational part of most analysts skills set.

Threats float in and out of visibility and may not leave a network, log or endpoint footprint. Additionally, there is a chance youre not collecting or monitoring one of the mentioned data sources. Brute force attack detections need to be made for each source; if its targeting your SSO, it may not have a network or host footprint. The same can be said for other attacks.

Within SOCs, this creates an exponential amount of detections to be made. SOCs can often suffer from alert fatigue, trying to detect suspicious activity across multiple applications. This creates the need for high quality detections. To detect and identify malicious activity without burying yourself in noise.

Creating high quality detections is a skill, and similar to languages, once learned can be applied across platforms and technologies. An example of a more advanced detection could be one that identifies a users most common historical IP addresses for Okta. This can then facilitate alerting on activity that was previously too noisy. Being able to operationalize and improve the efficiency of alerts makes you a force multiplier within SOCs.

Similarly, threat hunting is also a skill. Often, youll be pivoting in the tool that youll be making a rule in, aggregating data together, slicing it, performing long tail analysis and investigating telemetry alerting. It is vital to develop the ability to visualize data in a way that produces high quality threat hunting leads, identifying and bringing obscure activity front and center.

SOC analysts use a variety of tools for different purposes. Learn to be flexible and adapt to different tools instead of relying on one particular tool.

SOC analysts must be proficient in various tools and technologies used in cybersecurity. However, becoming too reliant on a specific tool or technology can hinder SOC analysts ability to analyze and respond to security incidents effectively.

Being overly reliant on a specific tool or technology can lead to several risks for SOC analysts. First, analysts may not be able to see the complete picture of their organizations security posture if they only rely on a specific tool or technology. This can result in missed security incidents and vulnerabilities. Using multiple tools that need to be integrated is a common cause of inefficiencies in SOC analysts workflows. This can result in delayed incident response times and increased workload. Relying too heavily on a specific vendors tool can result in vendor lock-in, making switching to a different tool or vendor difficult if necessary.

To effectively master the art of SOC analysis and be tool agnostic, SOC analysts should follow these best practices:

As the threat landscape evolves, SOC analysts must remain agile and adaptable to effectively detect, respond to, and mitigate security incidents. Being tool agnostic is a crucial component of this adaptability, enabling SOC analysts to select and use the best tool for the job, regardless of vendor or technology.

As more data breaches and ransomware occupy news headlines worldwide, enterprise leaders understand the absolute need for robust cybersecurity services such as security operation centers (SOCs).

Investing in aspiring security professionals means operational teams can detect intrusions and rapidly isolate them before they move deep into a sensitive environment and create long-lasting damage. SOC analysts are an essential part of this defense, proactively monitoring for early indicators of threat, providing real-time responses to security events, triaging actions, recovering assets, and triggering incident recovery mechanisms.

For aspiring SOC analysts, a combination of technical knowledge, analytical skills, and critical thinking abilities ensure they can truly understand the digital environment they are protecting. Together with the right stack of security tools, cybersecurity strategy, and top-down support from enterprise leadership, SOC analysts can keep their businesses safe from evolving threats in the cyber landscape.
