Real-Time Security Monitoring with Log Center
Using Synology Log Center to Keep an Eye on Security in Real Time
In today’s world of threats, prevention isn’t enough on its own. Companies need to be able to quickly find and respond to suspicious activity before it gets worse. Synology Log Center lets you keep an eye on system events, keep track of access attempts, and get real-time alerts all in one place on your NAS.
Log Center turns a Synology NAS from a simple storage device into an active security monitoring platform when it is set up correctly.
Why Real-Time Monitoring is Important
Cyberattacks are happening more often and are more automated. Bots are always looking for NAS devices that are open, weak passwords, and open services on the internet. Data can be compromised even by internal risks like unauthorized file access or accidentally setting things up wrong.
Monitoring logs in real time helps find:
- Brute-force attempts to log in
- VPN connections that look suspicious
- Accessing files without permission
- Breaking the rules of the firewall
- Service crashes or acts strangely
The sooner you find problems; the sooner you can fix them.
What Log Center Really Keeps an Eye On
Synology Log Center gathers and organizes logs from a number of DSM services, such as:
- Events when you log in to DSM
- Connections to VPN servers
- Accessing files
- Firewall events
- Logs for packages and applications
- Warnings from the system and alerts from the hardware
You don’t have to check each service separately anymore with this unified view.
Setting up and enabling Log Center
To begin:
- If you don’t already have it, install Log Center from Package Center
- Turn on the collection of system logs
- Set up policies for keeping things
- Enable detailed logging for important services like VPN and Firewall
Make sure that logging is set up to record authentication events as well as system errors. More detailed logs make it easier to see what’s going on for security analysis.
Making Alerts in Real Time
Monitoring only works if alerts can be acted on. You can set up notification rules in DSM based on certain events.
Some examples of alert conditions are:
- More than five failed login attempts in a short amount of time
- VPN connections outside of regular business hours
- Access from IP addresses that aren’t known
- Repeated blocks by the firewall
Set up email or SMS notifications to get alerts right away. For bigger environments, sending logs to a SIEM platform gives you more powerful analytics tools.
Finding patterns that look suspicious
Logs give you raw data, but correlation gives you insight. Look for things that happen over and over again, like:
- Several failed login attempts, then a successful login
- Repeated attempts from the same IP address in another country
- Strange spikes in the number of file downloads
- Restarts of service without warning
Checking logs on a regular basis helps you find threats that are moving slowly and might get past automated blocking rules.
Making security stronger by keeping logs for a long time
Forensic analysis and compliance both depend on keeping logs properly. Set up Log Center to keep logs for long enough to look into incidents while using storage space wisely.
For business use, think about:
- Putting logs in a safe archive
- Sending logs to centralized monitoring systems
- Encrypting log data that is saved
Keeping detailed logs helps meet both security and legal needs.
Using Log Center with Other Synology Tools
The best way to use Log Center is as part of a layered defense plan. Put it with:
- Rules for the DSM Firewall
- Account safety and automatic blocking
- Two-step verification
- Snapshot Replication to protect against ransomware
These tools work together to make a single platform that can detect, stop, and recover from problems.
About Epis Technology
Epis Technology helps businesses set up structured monitoring frameworks for their Synology deployments. The team sets up Log Center policies, connects logs to larger security monitoring systems, and makes sure that alerts match up with tracking of firewall and VPN activity. They also use Microsoft 365 backup monitoring and hybrid cloud replication alerts to make sure that the whole data environment is visible. Businesses can see what’s going on in real time instead of having to wait for problems to happen and then fix them.
