Dev and Security Walkthroughs

Another Pokemon Capture Salesforce Certifications remind me of Pokemon. There are 25 different certifications to pick from. They range from easy to hard. Some have prerequisites before they can evolve. Some gyms (jobs) want you to collect 2 or more. They are hard to catch but easier to keep. I passed my Advanced Admin today. That marks my forth Pokemon capture. I picked Advanced Admin because it is on the Q Branch list. Otherwise I would have pursued it much later. A big regret of mine is not getting these certifications sooner. Many Salesforce Developers stop at PD1. I stopped at PD1. I started Salesforce mid-2018 and only had PD1 for 1.5 years. I got my Admin January 2020. When I was job searching most jobs wanted a combination of PD1, Admin, App Builder, Sales, Service, and PD2. I got the Admin Pokemon in January to accompany me on my job search journey. Late 2019 was a bad time to realize 'Wow these Salesforce certifications seem important. What have I been doing?...

Intro to Missing People OSINT Course with Joe Gray: Review Course: Intro to Missing People OSINT Taught by: Joe Gray I found Joe's course on the TraceLabs slack channel. I saw Joe is a winner of multiple CTF competititons from Derbycon, Defcon, to TraceLabs. I thought it would be good to get his insight and a different perspective on OSINT. CCDC now.. Missing People? The interest started at Akron. University of Akron has a digital forensic presence. I didn't take any digital forensic classes and regret it. I could have worked home one day a week, left the office early, or some sort of plan. The sad ship has sailed since I'll be in Chicago. I think this happened because my interest went from 0 to 75 and by the time I got interested, it was too late! If I went to Akron (back in 2015-2018), I probably would have double majored in Computer Science and Digital Forensics, with a certificate in DISASTER! The only reason being when a project is going wrong I can say...

Lab #3 is here: Ipversity Well this one took me two days and I needed to whiteboard it. The Smartphone, WLAN was simple, getting to 8.0.0.2 got me. I thought the creator set up a Static Route to send 192.168.1.0/24 and 10.0.0.0/24 traffic back to our internal DNS Server. Then I thought hmm.. I can't set up/change Static Routes (its in the rules), do they want me to NAT it? Nothing is said about OSPF either. Its quite possible NAT and/or OSPF is a solution to this network topology. I will update this blogpost when the creator publishes his solution. Ipversity Lab #3 Writeup Step 1: This step might seem odd, but after research I wanted to tackle OSPF first. Remote Core uses OSPF 1 with router-id "10.10.10.10". HQ Core uses OSPF 1 with router-id "20.20.20.20". Lets set up OSPF1 with router-id "30.30.30.30" on Router0. Great, now MGMT-PC can ping 8.0.0.2. Lets change the MGMT-PC DNS entry to point to 10.0.13.5. Lets configure our WLAN. O...

Fix My Lab Challenge #2 (5-4-20) Link to Lab: https://ipversity.com/fix-my-lab I was so focused on the IP Phones I learned about them, and then realized they were bait. This video shows how to configure Cisco IP Phones: https://www.youtube.com/watch?v=RB4LiS2lIXo . You don't need to know, but its interesting anyway. The Layer 3 Switch in Packet Tracer can't handle VoIP. A Router can. I looked on Youtube and found 0 vidoes on L3 Switches being the main source for VoIP. Its probably possible on GNS3 and physical equipment. Not so for Packet Tracer. The objectives never point out to fixing VoIP. The phones are just there to distract and trick you. Treat them like they are invisible. I never knew a connection could pass with a non-configured Cisco IP-Phone. I tried to enable "ip routing" on the L3 Switch and that did not turn the telephony option on. The initial config on the Switch ACTS as if VoIP will work, with DHCP set up for vlan 10 "DATA" and vlan ...

I haven't touched Cisco since CCDC. I found Ipversity on twitter and thought this would be good practice for my rusty skills. I remembered most of the commands and even how to implement OSPF. During my Cisco 1 and 4 classes, I always wished there was a 'Fix this network topology' website that was like Vulnhub. Well its finally here! I couldn't wait to dive in. Warning - Spoilers Lab 1 The first thing I do is get out a piece of printer paper. I draw the diagram and use markers to see the connection. I write down interfaces and IP addresses too. I start on the end-devices and work my way inwards. The second thing you need to do is turn on interface g0/0/1 on Router 1 (I'll call it B due to habit). Packet Tracer will show the red triangles which means its off. The next step is to fix the subnet mask on RouterA's g0/0/1 interface. It should be 255.255.255.252, not 255.255.255.240. Our OSPF config won't like this. Do a shut/no shut once you ch...
