Maltego (www.maltego.com) is a fantastic tool to help with OSINT. It's a relationship-based graphing tool with dynamic plugins to help you acquire and organize information against your target(s). I can't recommend it enough.

If you haven't already, try Linux From Scratch (www.linuxfromscratch.org/lfs/) which walks you through building a Linux completely from source code. It's a great way to understand how systems work, toolchaining and that "C" is the OG programming language.

Don't forget to take a break, decompress and make sure to use your vacation time. For instance, I'm taking next week off for a stay-cation.
Regardless of how much time you take, #MentalHealth is extremely important, especially in any #tech field.

Network Address Translation (NAT) modifies either (or both) the source and/or destination Layer-3 address of a packet. There are two ways to implement NAT:
Hide NAT which is a "many:one" ratio and
Static NAT which is a "one:one" ratio
You can NAT with IPv6 but... Why? 🙃💚

Getting rid of a disk? Zero it out (at least) three times by "imaging" it with the `/dev/zero` character device.
dd if=/dev/zero of=/dev/sda bs=4M
⚠️ Make SURE you triple-check which device you're using as your output file (of=) to make sure you don't lose your active disk.

Sub-policies in #CheckPoint #firewall let you create one overarching rule to cover an entire section and then narrow down specifics. This saves on processing time as packets not destined for the parent rule are skipped.

Upgrading? Make sure you also download the currently running firmware in addition to the upgrade version. If things go wrong and you have no Internet access, you have a known-good image you can load.

Most numeric keypads have a Braille button on the "5". Memorize this so that you can cover your PIN entry with your other hand to prevent cameras from seeing what you're PIN is. Bonus points for having repeating digits in case the camera is thermal. Also, jiggle the keypad.

Burp Suite lets you intercept HTTP/S requests even before the TLS negotiation which allows you to modify both outgoing requests to a server as well as incoming responses from a server (not enabled by default). This lets you modify data going to the server...

/tmp and /dev/shm are two temporary storage areas on a *nix system. While /dev/shm may not be there (depending on your OS), /tmp is always there. Contents stored in /tmp are stored in virtual RAM so if you have swap space configured, the contents *may* end up on disk.

To load the first binary on device 8 on your #Commodore64, you would run `LOAD "*",8,1"` Once loaded, you issue the `RUN` command to execute it.
Want a directory listing of the device instead?
`LOAD "$",8` followed by `LIST`

To check the connections currently running through a #CheckPoint firewall, run: `fw tab -t connections -s` for a full summary. Be careful! Running `fw tab -t connections -x` will drop all the connections. Always verify which command switch you've typed especially in prod.

You don't have to send the output of a command to pipe through grep if the targets of the command are grep-able.
Don't: `cat ./myfile.txt | grep -i somestring`
Do: `grep -i somestring ./myfile.txt`

A traditional #VPN can be daunting if you're not familiar with it so here's some info that will help you out. There are two phases aptly referred to as Phase-1 and Phase-2. Phase-1 can also be called Main Mode (or Aggressive Mode) and Phase-2 is also known as Quick Mode.

Dynamic Trunking Protocol (DTP) is used to allow switches to share trunk information to reduce configuration however it poses a security risk should a Threat Actor plug into a port with DTP enabled. *Always* keep unused ports in `shutdown` mode and assign them a dead VLAN.

Open Shortest Path First (OSPF) is a dynamic routing protocol that allows for fault tolerance and optimized hop-based routing. It's one of the most often used interior routing protocols.

On IPv4 networks, Address Resolution Protocol (ARP) is the mechanism used to locate the physical address of NIC and map it to the IP address. ARP does not cross Layer-2 boundaries so the skid saying he sees your MAC address across the internet is lying.
