Location: C:\Users\Admin\Downloads\file123.exe
Action Taken: Quarantined
Status: Success
2. Firewalls
Firewalls act as security barriers that control incoming and outgoing network traffic. They enforce security policies by allowing safe traffic and blocking suspicious or unauthorized connections.
Types of Firewalls
- Packet-Filtering Firewalls
- Stateful Inspection Firewalls
- Proxy Firewalls
- Next-Generation Firewalls (NGFW)

- Cisco ASA
- Check Point Firewall
- Palo Alto Networks Firewall
Firewall Rule Example
ALLOW: 192.168.1.0/24 → ANY → Port 80 (HTTP)
DENY: ANY → 10.0.0.5 → Port 22 (SSH)
3. Intrusion Detection and Intrusion Prevention Systems (IDS/IPS)
IDS and IPS tools analyze network traffic for abnormal patterns. IDS only detects and alerts, while IPS detects and actively blocks threats.
Popular IDS/IPS Tools
- Snort
- Suricata
- Zeek (Bro)
