Texas Network Security Operations Center (NSOC)

NSOC Overview 

If you are a State Agency or customer of the State Data Center or using DIR’s NSOC for internet connectivity, we provide several key services. We provide incident handling and security operations for all Shared Services and NSOC customers to include the following: 

• DIR-provided internet services 

• Managed Security Services (MSS) 

• Texas.gov/Cloud 

• Data Center Services (DCS) 

Beyond providing internet access to state agencies and eligible partners, the NSOC provides real-time 24x7 intrusion detection and blocking of suspicious and malicious activity. Our monitoring covers both inbound and outbound traffic. Should we see something suspicious going in either direction we will both alert and work with you to resolve any issues discovered.   

Network Security Monitoring, Alerting, and Analysis Services 

These services provide early warning for attempted intrusions, distributed denial-of-service (DDoS), and cyber-attacks, as well as alerts to authorities that facilitate appropriate countermeasures. Advantages include: 

• Saves time with event correlation 

• Integrates security analysis 

• Saves money through reduced risk 

• Meets audit requirements 

• Prevents attacks and provides early warning 

• DDoS detection and mitigation 

Network Intrusion Prevention Service (IPS)  

This service proactively identifies, and blocks known threats to network security. The IPS not only watches network traffic, but also takes immediate action based on the network administrator’s set of rules.  An IPS: 

• Prevents malicious activities at multi-gigabit speeds 

• Mitigates detected threats 

• Blocks millions of attacks monthly
