Overview:

Holley's Premium Mid-Mount complete accessory system has all accessories pulled in tighter than other accessory drives. At the heart of the system is a "bracketless" design (Patent Pending), where the accessories bolt directly to the water pump for a clean, integrated form. The design offers superb engine visibility to show off your horsepower, not your accessories. Among the many swap friendly features are bottom heater outlets for clearance in tight applications. The Holley designed alternator is just as innovative. This premium alternator utilizes 6-phase technology as found on the C7 Corvette. The water pump also shares its design efficiencies with that of the C7 Corvette. The compact and reliable SD7 A/C compressor and Type II P/S pump with baffled reservoir are also integrated. The Mid-Mount drive completes Holley's trilogy of accessory solutions giving a third option compared to the High and Low-Mount previously released. All three accessory solutions are for LS engines. When we say "complete", we mean complete. The Mid-Mount system comes with everything you need. All accessories are included; the water pump, A/C compressor, Alternator, P/S pump with reservoir, and an SFI certified damper w/hard anodized billet crank pulley. All pulleys and the belt are supplied. Even heater hose adapters, power steering to -6 AN hardline, and the alternator plug/harness are included. Easy assembly was a priority during the entire development of this accessory solution. Color graphical instructions walk you through every step of the ultra-easy installation. The Premium Mid-Mount system comes with dress up pulley covers and an SFI certified damper. Partnered with this damper is a billet 6061-T6 aluminum hard anodized crank pulley. This system is ready for the racetrack if you want to play or just be ready for anything on the street.

Essential Forensics Book
Format: Paperback
I am impressed with the broad range of topics that this book covers. I came out of a Cybersecurity program with a Digital Forensics specialization, so I did have networking knowledge. I looked for resources after graduation to help fill the gaps (courses, books, and tool manuals) in my understanding of the space where networking and forensics meet and found the coverage to be lacking. This book would have helped to tie the two together for me in an easy to read presentation. I am glad that I have read it now though and will keep it as a resource. I bought two more copies to give to current Digital Forensics students that I am mentoring:) Well done on this one!

This book is the real deal
Format: Paperback
This book is the real deal. I found it to be eye-opening, because, despite sounding very advanced and almost next-level, the attacks accompanied by source code show how simple and effective they are in reality. This book seemed light at first (200 pages), so I was skeptical at it's ability to really tackle advanced topics, but I will say I was very pleasantly surprised. Those two hundred pages are action packed and filled with jaw-dropping 'this is cool' moments. My only gripe with it is that it's a little formulaic, with the social engineering being shoehorned into every attack, and maybe pushing the whole APT thing too much, like when you really want something to become 'a thing'. Do we really need to socially engineer payloads using the same formula for all of the attacks? Not even one 'ha Ked the router with boring Cisco exploits' example? I guess it wouldn't make for an entertaining book.

Best pentest book read to date
Format: Paperback
This is the best penetration testing book that I have ever read to date. There is such a depth of understanding of penetration testing that is conveyed in this book in the way that the author is able to portray highly advanced topics in a conceptually understandable way. A novice might not be able to follow the text, as it is advanced, but for anyone looking to open their mindset up to becoming a more effective penetration tester, I HIGHLY advise this book.

Worth every penny
Format: Paperback
This book is in a class of its own compared to other security and pentesting books. I would highly recommend to anyone interested or currently working in network security. Instead of simply explaining how to use common pentesting tools, Wil Allsopp explains how they work and how to write your own custom tools from the ground up. Even if you do not have a programming background, it is worth understanding how an attacker can infiltrate a "secure" network without being detected.
