I was recently in Houston Texas for a conference and I took a stroll in downtown area during my free time. I started off with Sam Houston Park where you can see historic houses built in the 1800s.
I went to see Toyota Center and Minute Maid Park which are just few blocks away from each other.
I had lunch at Jackson Street BBQ which is just right across Minute Maid Park. I ordered a mix platter of sausage, pork ribs and beef brisket, a side of mashed potato and Dos Equis beer :)
This is the dinner I had at Rudy's BBQ. I ordered a pulled pork sandwich, banana pudding for dessert and sweet tea.
A penetration test (often called a pen test) is designed to simulate an attack on a system, a network, or an application. Its value lies in its potential to discover security holes that may have gone unnoticed. It differs from a vulnerability test in that it attempts to exploit vulnerabilities rather than simply identify them. Penetration testing should be an operation that occurs at regular intervals, and its frequency should be determined by the sensitivity of the information on the network.
The steps in performing a penetration test are as follows:
Step 1. Planning and preparation
Step 2. Information gathering and analysis
Step 3. Vulnerability detection
Step 4. Penetration attempt
Step 5. Analysis and reporting
Step 6. Cleaning up

There's a program (a GUI) in Kali Linux called Maltego that automates DNS data mining and it has graphs showing the relationships between entities (such as Company, web sites, etc.).
It will ask you to setup a login. You’ll need to activate your new account in Paterva’s website.

There's a program (a GUI) in Kali Linux called Maltego that automates DNS data mining and it has graphs showing the relationships between entities (such as Company, web sites, etc.).
Click on Maltego on the left hand corner.
Choose Maltego CE (Free) > click Run.
It will ask you to setup a login. You’ll need to activate your new account in Paterva’s website.
I chose not to send Error Reports (just leave it uncheck). Click Finish.
Click on Create a new graph (dark page with + on upper
left corner).
Click and drag Domain on the white space. It would
show peterva.com by default. You can change the domain name by doing a double click
and type the new domain name.
Do a right-click > choose the Transform command to run
> click the forward arrow icon to run.
I chose to run the DNS from Domain.
