What are the common signs of a compromised network?

Key signs that indicate a network has been compromised include:

1. Unusual Network Activity: Monitoring for sudden spikes in data traffic or unusual patterns that are different from normal network behavior.

2. Unauthorized Access Attempts: Any unauthorized attempts to access sensitive network resources or unauthorized login attempts.

3. Changes in System Settings: Changes in system configurations, software installations, or unauthorized modifications of critical files or settings.

4. Unexplained Account Lockouts: Frequent account lockouts or password reset requests without legitimate reasons.

5. Unknown Services or Accounts: Discovery of unknown services running on network devices or presence of unauthorized user accounts.

6. Unexpected Outbound Traffic: Unusual outgoing network traffic to suspicious or unverified destinations.

7. Unexplained Data Exfiltration: Detection of sensitive data leaving the network without authorization.

Teams can detect these signs early by implementing proactive security measures such as:

1. Network Monitoring: Use security tools to continuously monitor network traffic, detect anomalies, and suspicious activities.

2. Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS): Deploy IDS/IPS solutions to identify and respond to potential security breaches in real-time.

3. Regular Security Audits: Conduct regular security audits and vulnerability assessments to identify weaknesses in the network infrastructure.

4. User Behavior Analytics: Implement user behavior analytics tools to detect abnormal user activities and suspicious behavior.

5. Employee Training: Provide cybersecurity training to employees to raise awareness about
