Upgrading Palo Alto

Upgrading Palo Alto is very easy in compared to any other next generation firewall. We just need to be careful with few of the things

1. Downloading software

Go to Device > Software and we will need to check which software version are we trying to upgrade to.

Note : We cannot directly jump for one major version to another like from 9.1.x to 10.1.x. We will need to go from 9.1.x to 10.0.x. This is how it normally works in most of the firewall.

We now need to select the version we want to install it and directly download it to our software repository. As our PA 3220 is in HA we can also directly sync the downloaded software to our secondary PA 3220.

2. Installing Software

Once we download the software we can now install the software. The software upgradation process does take around 10-15 mins approximately. Palo Alto will reboot and gets started automatically.

3. Verification

Palo Alto has now rebooted and is upgraded as well.

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: ...

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...

Upgrade Catalyst C9500

Upgrading Catalyst 9500 series switch is relatively easy. The one that I'm going to upgrade today is on Install mode containing packages.conf file. Install mode consumes far less resources in compared to the traditional bundle mode and has some advantage like auto upgrade when configured in stacked mode. We can talk about the difference between bundle and install mode later on. Let's focus on upgrading the Catalyst 9500 switch. Switch I am trying to upgrade is in 17.03.03 which has some bugs and security vulnerabilities. I am upgrading it from 17.03.03 to 17.6.5(MD) golden image present in the cisco download site for C9500 series switch and also reading down the linked document from cisco that is what they recommend. You can have a look at it . https://www.cisco.com/c/en/us/support/docs/switches/catalyst-9300-series-switches/221498-recommended-releases-for-catalyst-9200-9.html We will first need to create FTP username and password in the switch. The username and password must b...
