Check Point
A Check Point is a network security appliance(Firewall) which uses in prevent your network from unauthorized access.In previous years there were two type of firewall in world of network security.
1. Packet Filtering Firewall
A Packet Filtering Firewall is type of security appliance who inspects the IP packet parameter source IP, destination IP, source service port and destination service port only. By using access control list we can easy to control(Permit and Deny) any network and individual host request traffic.
Example: Cisco Access Control List
a. Standard Access-List
access-list 1 permit 10.1.5.1
access-list 1 deny 192.168.1.53
b. Standard Access-List with wildcard mask
access-list 1 permit 172.30.0.0 0.0.255.255
c. Name Access Control List
ip access-list standard NAME
permit 10.1.5.1
deny 192.168.1.53
permit 172.30.0.0 0.0.255.255
d. Extended Access-List
access-list 110 permit tcp 92.128.2.0 0.0.0.255 any eq 80
e. Reflexive Access Control-List for IN and OUT traffic
ip Access-list extended reflexive
permit ip any any reflect ip_database
permit tcp any any reflect tcp_database
permit udp any any reflect udp_database
f. Time Based Access Control-List
time-range time_flow
absolute start 00:15 1 July 2018 end 00:20 1 July 2018
time-range Periodic
periodic weekdays 0:15 to 0:20
ip access-list extended Time_acl
deny icmp host 10.1.1.1 host 10.1.2.2 time-range time_flow
2. Application Firewall
An application firewall is type of security appliance it can inspects the universal resource locator request and API request also.By using access policy we can easy to control(Allow and Deny) all requests generate by LAN and it have also intrusion detection system facility by using we can also monitor the malicious activity in your network.
Example: In Cisco router URL Policy
ip inspect name test http urlfilter
ip urlfilter allow-mode on
ip urlfilter exclusive-domain permit www.cisco.com
ip urlfilter audit-trail
ip urlfilter urlf-server-log
3. Hybrid Firewall
A Hybrid Firewall is next generation firewall and it is a combination of Packet Filtering Firewall and Application Firewall features. Hybrid Firewall have a features of software based URL filtering blade, Access Control blade, Intrusion Detection System blade and Intrusion Presentation System blade.
Example: Check Point and Cisco Firepower is a Hybrid Firewall.
In this blog we read about Check Point R77.30
History of Check Point
Check Point firewall is a Gaia operating system based security appliance.Check Point was established in Ramat-Gan, Israel in 1993, by Gil Shwed. Check Point has invented state full inspection technology who is fundamentals of network security appliance.Gaia operating system is best feature combination of IPSO((Nokia)Unix Based) SPLAT((Secure Platform)Linux Based) and it is also unified operating system providing greater efficiency and robust performance.
