Actually, before I got involved in this industry, I was not very familiar with the word "SOC". However, as I listened to the stories of various companies, I began to feel strongly that this is an indispensable part of modern companies.
In this article, we'll bring you everything from the basics of SOC to the needs of your company and tips for implementing it!
What is **"SOC" in the first place? **
"SOC" stands for Security Operations Center. Literally translated as "security operation center". In other words, a specialized team or system that monitors a company's systems and networks 24 hours a day, 365 days a year, and responds to any signs of a cyberattack.
Specifically, they will do the following:
- Real-time monitoring of cyber attack signs and suspicious communications
- Detect alerts (anomalies) and analyze them quickly
- Escalate to relevant departments and management as necessary
- Initial response and recovery support in the event of an incident (damage)
- Daily log audits and vulnerability information capture and reporting
When you hear this, you may think, "It seems difficult" or "It's for large companies." However, in fact, regardless of size, companies play an important role in protecting information.
**Why is SOC needed now? **
This has a lot to do with the increasing sophistication and diversification of cyberattacks.
In the past, there was a time when it was safe to put antivirus software in. But now, ransomware, phishing, internal fraud, zero-day attacks, and all sorts of other forms of corporate information are being targeted.
To make matters worse, it is common practice for attackers to gradually infiltrate the interior so that they go unnoticed.
That's why it is necessary to have a system that quickly notices abnormalities. That's exactly what SOCs do.
**What happens if you don't have a SOC in your company? **
Companies without a SOC are prone to the following challenges:
- Detect alerts but don't know who should do what
- The person in charge is concurrently working on a separate task, causing delays in security responses.
- In the event of an incident, the initial response is delayed and the damage increases
- "I don't realize something was happening in the first place"...
In particular, if the number of people in the IT department is limited or there are no security experts in the company, you may be in a state where you can notice a problem and do nothing.
This is how a company changes when there is a SOC
Conversely, in a company with a SOC, what happens:
- When an abnormality is detected, a professional team immediately analyzes and makes a decision.
- Only important alerts are notified, reducing the burden on your work
- Strengthened security posture and increased trust from business partners
- Management is also regularly reported on what risks there are now.
In other words, a sense of security is created that allows you to concentrate on your work.
**Is a SOC built in-house? Is it outsourcing? **
A common question here is, "Should I make a SOC in-house or should I ask an external party?" That's the point.
⬛ When building your own SOC
Pros:
- You can create your own environment
- Know-how accumulates within the company
Cons:
- Need to recruit and train specialized personnel
- High cost of maintaining a 24-hour system
- Alert response is easy to personalize
⬛ When using an external SOC service
Pros:
- Immediate assistance from a professional team
- Reduce labor and education costs
- Ability to respond by utilizing the knowledge of multiple companies
Cons:
- Need to familiarize yourself with the service specifications at first
- Psychological hurdles to outsourcing security
Colorkrew Security's SOC services are the best way to get started.
"We may need a SOC too... But I don't know where to start."
In such cases, it is recommended to start by using an external SOC.
Colorkrew Security has a large number of implementations for small and medium-sized enterprises, and provides careful support from initial design to operation.
