A Security Operation Center (SOC) is a centralized function within an organization that uses people, procedures, and technology to continually monitor and enhance the security posture of an organization when it comes to avoiding, detecting, analyzing, and responding to cyber-attacks.
The key function of SoC
- Make a list of the resources you have at your disposal:
The Security operation center is in charge of two categories of assets: the devices, processes, and applications they’re tasked with protecting, and the defensive tools they have at their disposal to assist them to do so.
- What the SOC Guards: The Security operation center can’t protect devices or data that they can’t see. There are likely to be blind spots in the network security posture that can be detected and exploited without visibility and control from device to cloud. As a result, the SOC’s purpose is to have a full picture of the company’s threat environment, which includes not just on-premises endpoints, servers, and software, but also third-party services and traffic moving across these assets.
- What the SOC does to keep you safe: The Security operation center should also have a thorough awareness of all cybersecurity tools on hand as well as all SOC workflows. This improves the SOC’s agility and allows it to operate at maximum efficiency.
- Preparation and Maintenance (Preventative):
Even the most well-equipped and agile response systems fall short when it comes to preventing crises in the first place. The Security operation center employs preventative measures, which can be separated into two groups, to assist keep attackers at bay.
Members of the team should stay up to date on the latest security advances, cybercrime trends, and the emergence of new dangers on the horizon. This research can be used to assist create a security roadmap that will guide the company’s cybersecurity activities in the future, as well as a disaster recovery plan that will provide ready guidance in the event of a worst-case scenario.
- Maintenance as a preventative measure:
All activities are done to make successful attacks more difficult, such as regularly maintaining and updating existing systems, updating firewall policies, patching vulnerabilities, and whitelisting, blacklisting, and securing apps, are included in this phase.
- Continuous Proactive Surveillance:
The SOC’s tools scan the network 24 hours a day, seven days a week, looking for any anomalies or suspicious activity. The Security operation center can be warned of developing risks promptly by monitoring the network around the clock, providing them the best chance to avoid or mitigate harm. A SIEM or an EDR are examples of monitoring tools. The most advanced of these can employ behavioral analysis to “teach” systems the difference between normal day-to-day operations and genuine threat activity, reducing the amount of triage and analysis required by people.
- Alert Management and Ranking:
When monitoring tools send out alerts, it’s up to the SOC to examine each one carefully, delete any false positives, and decide how aggressive any actual threats are and what they might be targeting. This enables them to effectively prioritize emerging threats, addressing the most pressing concerns first.
- Response to a Threat:
The majority of individuals associate the managed SOC with these behaviors. The SOC responds as a first response as soon as an incident is confirmed, shutting down or isolating endpoints, stopping malicious programs (or blocking them from executing), deleting files, and so on. The goal is to respond to the extent required while minimizing the impact on company continuity.
- Remediation and Recovery:
Following an incident, they will try to restore systems and recover any data that has been lost or compromised. Wiping and restarting endpoints, restructuring systems, or, in the case of ransomware attacks, establishing valid backups are all possible ways to avoid the malware. This step, if completed successfully, will restore the network to its pre-incident state.
- Management of Logs:
The Security operation center is in charge of compiling, maintaining, and evaluating a log of all network activity and communications for the whole company. This information helps create a baseline for “normal” network activity, can show the presence of risks, and can be utilized for post-incident remediation and forensics. Many SOCs employ a SIEM to collect and correlate data from applications, firewalls, operating systems, and endpoints, all of which generate their own logs.
- Investigation of the Root Causes:
Following an incident, the SOC is in charge of determining exactly what happened, when, how, and why. During this inquiry, the Security operation center will use log data and other information to trace the problem back to its source, which will aid in the prevention of future problems.
- Refinement and Enhancement of Security
Cybercriminals are continually improving their tools and techniques, and the Security operation center must keep up with them by implementing upgrades on a regular basis. The strategies established in the Security Road Map are brought to life in this step, but it can also involve hands-on techniques like red-teaming and purple-teaming.
- Management of Compliance:
Many of the SOC’s processes are guided by best practices, but others are driven by regulatory obligations. The Security operation center is in charge of auditing their systems on a regular basis to ensure compliance with any requirements imposed by their company, industry, or regulating authorities. GDPR, HIPAA, and PCI DSS are examples of these regulations. Acting in line with these regulations not only protects the sensitive data entrusted to the firm, but it also protects the company from reputational harm and legal problems which might come as a result of a breach.
