BIG IP F5 AWAF Fundamentals

Big IP F5 AWAF ( Advanced Web Application Firewall) formerly known as ASM ( Application Security Manager ) provides great enhanced web application security protecting against sophisticated attacks like Cross Site Scripting Attack, Cross Site Request Forgery Attack, SQL injection and so on. Big IP F5 works along with both negative and positive security model.

Deploying F5AWAF Let me talk about some of the key security features that F5 provide right from the go.

SAN Switch Zoning with Brocade

Zoning in Brocade SAN Switch Let's begin with resetting the switch completely. In my environment I have two brocade SAN Switch connecting to 2 Dell R940 server configured with VMware. The SAN switch will be having connectivity between Dell Unity 500 storage and Dell R940 servers. Multipathing will be done between the server and storage with the help of SAN Switch. Multipathing, also called SAN multipathing or I/O multipathing, is the establishment of multiple physical routes between a server and the storage device that supports. It results in better fault tolerance and performance enhancement. DESIGN The idea behind zoning is that intended WWPN talk with each other . This is more like ACL in the world of Ethernet. To see the devices which are logged into the switch the following commands can be executed. SAN-A:admin> switchshow switchName: SAN-A switchType: 118.1 switchState: Online switchMode: Native switchRole: Principal switchDomain: 1 switchId: ...

Device Mapper Multipath with LVM in Oracle Linux

This blog describes you the step by step procedure for configuring multipath in liunx using Device Mapper and will also help you understanding what Device Mapper is. Simply stating Device Mapper is an interface to Linux Kernel which helps us to configure multiple I/O path between the server and the storage arrays. Device Mapper interface allows the linux kernel to communicate with LVM Logical Volumes, EVMS Volumes , Software RAID, multipath and many other solutions. Multipathing is a must for all those mission critical applications as we all know that data is the most important thing in an enterprise network . Let me now share the installation process for multipathing. Installing Device Mapper #yum install device-mapper-multipath -y #rpm -qa | grep device-mapper Enabling Multipath #cp /usr/sare/doc/device-mapper-multipath - */multipath.conf /etc/multipath.conf #mpathconf -enable -user_firendly_names n #modprobe dm_multipath #lsmod | grep dm_multip...

SSL Decryption FortiGate

We have pretty much heard about SSL decryption and of malware hiding inside an encrypted traffic. A large amount of traffic in the internet is pretty much encrypted which basically means that bad things like malware, virus, ransomware can hide inside this encrypted traffic. If majority of these traffic are encrypted our Firewalls are not able to analyze these traffic which can easily infect our organization and the investment which we have done in these firewalls are wasted. There does come around a solution for this and as my topic suggest SSL Decryption also know as Deep Packet Inspection as by some IT folks. The image that I have attached down below clearly suggest about what I am trying to explain. Using deep packet inspection, the firewall simply decrypts the encrypted traffic happening between client and server, inspects the content to find the threats and block them , then forwards it to the destination re-encrypting it . We will need to first setup the SSL/SSH in...
