From whom to protect ?

  • Hackers : Who want to steal confidential information

  • Phishers:  Who intrude and setup autonomous system or lure victims host for fraudulent activities
  • Others : Attacker some time just want to disrupt the system by flooding or other methods by using Dos(Denial of Service) attack

How to Protect ?

  • Firewall : Deploy Hardware or Software firewall to block unsecure ports and segmenting network into DMZ (Demilitarize) and Militarize Zone(MZ)
  • OS Security: Hardening OS security by tuning kernel parameters and fixing bugs which leave security loop holes
  • IDS/IPS Deployment : Intrusion Detection System (IDS) reads packet header and signature and checks if the traffic is unsecure or secure whereas Intrusion Prevention System blocks the traffic identified by IDS.
  • Check for Malicious Software : Virus , trojan , malwares can leak information which can be used by intruder to intrude or affect the network or infrastructure.
