Intrusion Detection System (IDS) and Intrusion Prevention System (IPS) :
- These systems proactively monitor your network by analyzing network traffic and system calls to detect and mitigate suspicious activities.
NPAV IDS/IPS is engineered to detect and protect against various types of network attacks, including :
Port Scanning Attacks
A port scan involves systematically sending data packets to different ports on a networked device to identify which ports are open and what services are operational. This technique is utilized for :
- Vulnerability Identification : Pinpointing potential weaknesses in a system’s defenses.
- Traffic Analysis : Understanding the types of network traffic (e.g., web pages, emails, instant messages) handled by specific ports.
- Network Monitoring : Assisting network administrators in monitoring incoming and outgoing traffic.
While security analysts use port scanning to assess system security and identify open ports, cybercriminals exploit it to discover weak points within a network.
Distributed Denial of Service (DDoS) Attacks :
A DDoS attack is a malicious attempt to disrupt the normal traffic of a targeted server, service, or network by overwhelming it with a flood of internet traffic from multiple compromised computer systems. This coordinated attack can lead to :
- Service Outages : Rendering websites or services inaccessible to legitimate users.
- Financial Losses : Resulting from downtime, lost revenue, and recovery efforts.
- Reputational Damage : Eroding user trust and damaging the organization’s image.
- Business Disruption : Halting critical business operations.
Why it is useful and Impact on System :
- Real-Time Threat Monitoring :
Continuously scans network and system activity to detect and block suspicious behavior instantly. - Enhanced System & Application Security :
Protects against malware, ransomware, and unauthorized access, keeping both system and apps safe. - Detailed Logging & Alerts :
Provides actionable logs and alerts for quick response and forensic analysis of security incidents. - False positives :
IDS/IPS often generates false alarms, which can lead to alert fatigue and wasted resources investigating harmless events.
