**Why is security so important now? **
Recently, there is not a day that I don't see the topic of cyber attacks in the news. Ransomware, data breaches, phishing... There are already headache-making threats one after another. In fact, according to the 2024 Cybersecurity Report, about 60% of companies have experienced some kind of attack in the past year. This is not someone else's business.
If you are in charge of security operations, you must have this problem. "Are you protecting our system properly?" "Did you miss any suspicious logs?" "If something happens, can you respond immediately?" Microsoft Sentinel solves such concerns.
What is **Microsoft Sentinel in the first place? **
Microsoft Sentinel is a cloud-native SIEM (Security Information and Event Management) tool. To put it simply, it is a Sugremono that collects logs emitted from various systems and apps in one place and detects suspicious movements in real time. For example, employee PCs, cloud services, servers... It integrates all the disparate logs and tells you, "Oh, this movement might be dangerous!"
What makes it different from other SIEM tools? You may think. The biggest attraction of Sentinel is that it works closely with Microsoft's cloud platform (Azure). It can be easily connected to Office 365 and Azure logs, as well as external tools, so it runs smoothly in any environment. Moreover, the AI-powered analysis function is very smart! It pinpoints suspicious movements.
Why Log Integration Protects Your Business
You may think, "Log integration seems a bit of a hassle...", but in fact, this is a super important part of security. Why is that? I will explain the question in three points.
1. Everything can be visualized
It is actually quite difficult to check the logs for each system and for each individual management screen. But with Sentinel, you can see all your logs in one dashboard! In other words, it is like a control tower that overlooks the security of the company. This visualization greatly reduces the risk of missing out.
2. Catch Threats in Real-Time
Dealing with cyber attacks is a game of speed! If you delay even 1 minute or 1 second, the damage will increase. Sentinel can also use AI to detect unusual logins and suspicious file manipulation in real time. For example, it immediately detects and notifies you of suspicious movements such as "This user usually only logs in from Japan, but suddenly accesses from overseas."
3. Respond much faster
If you find a threat, it is meaningless if you do not respond immediately. Sentinel can automatically alert you to detected threats and even automate simple responses! For example, temporarily locking suspicious accounts. This reduces the burden on security teams and increases response speed.
How to Get the Most Out of Sentinel? Let's take a look at the issues
Did you find Sentinel useful from the explanation so far? However, there are some hurdles when it comes to actually using it. For example...
- Difficult to configure: In order to integrate logs, you need to design what logs are collected from which system. This is a bit of a hurdle for beginners.
- Difficult to operate: 24 hours a day, 365 days a year, it is difficult to monitor all the time! For example, if an alert goes off in the middle of the night, you will need to respond.
- Requires specialized knowledge: To properly understand and respond appropriately to AI analysis results, you need to have professional knowledge of security.
This is where Colorkrew Security comes in!
