Obviously this exam code is about to expire this month, but you can purchase the new test code version of this text book. I'm not sure how many CompTIA certification seekers are actually using Goodreads as a source for text book reviews, but I feel obligated to put my two cents in (let's be real I'm just trying to reach my reading challenge goal this year and every book counts). I did read this cover to cover and felt that it helped me with my studies. I highly recommend the paperback copy over the digital because you get free access to the online practice exams. The practice questions at the end of the chapters were decent, not overly difficult but just kept me on track. The two provided exams at the end were OK. The questions are all straight forward multiple choice questions. They're not like the real exam at all, it's kind of just like "you either know it or you don't" types of questions, which is helpful for just building your knowledge, but I would absolutely not use these practice exams to gauge your exam readiness. The book comes with two exam cram cheat sheets with a dump of key points you need to know for your exam, I read these over and over a few times before I went into the testing center.

This was probably the best resource out there for the NET+ as far as books go. I should mention that I did not read every page, rather I would use practice tests to gauge if I had any knowledge in a certain area and then use this book to create an actual base. There are others that I kind of skimmed but, in my opinion, they provided too much useless knowledge. This book gave you the essentials for passing the test.

EDIT: Took the exam today and passed handily. Great!

Definitely much more dry and to-the-point than the last one I read through, but I suppose that's the point of this series. It has good information, but I will say it does seem to pre-suppose a fair amount of knowledge or experience. If you're doing your certs in order, if you've read other intro materials, or if you have experience, that's totally fine.

I'll come back to this review after I take the exam for a more accurate review.

It doesn't go in depth into topics like CCNA related books, but it still contains valuable information that makes your journey smoother.

I only skimmed a few chapters, so I'm not rating it.

Notes
Models, Ports, Protocols, and Network Services
Session layer is responsible for managing and controlling synchronization of data between applications on 2 devices, by establishing, maintaining, breaking sessions.

Presentation layer handles encryption, including TLS.

Application layer: SSH, BGP, DHCP, DNS, NTP, RTP, SIP, SMTP, SMB, FTP, HTTP, IMAP, POP

Generic Routing Encapsulation (GRE): Cisco-created tunneling protocol used in VPNs and point-to-point (or point-to-multipoint) links.

Network Security
Fraggle attack: spoofed UDP packets are sent to network’s broadcast address, directed to specific ports to flood system.

Smurf attack: spoofed ping request sent to broadcast network address, and ping replies overload victim and prevent it from processing replies.

SYN flood/attack: victim is overwhelmed with flood of SYN packets. Attacker sends SYN, targeted server sends SYN/ACK response and waits for ACK. Attacker doesn’t respond with ACK, or spoofs destination IP address with a nonexistent address so no ACK occurs. Server fills with half-open connections, exhausting resources.

Distributed reflective DoS (DRDoS) attack (amplification attack): targets public UDP servers. Usually targets DNS or NTP, but can also target SNMP, NetBIOS, UDP.

ICMP flood (ping flood): large numbers of ICMP messages are sent to overwhelm system.

DNS poisoning (spoofing): DNS server is given false name server info. Can cause redirection of users to different websites, redirect email, or do other DNS-based redirection. Often uses fast flux (botnets hide delivery sites behind changing network of compromised hosts that act as proxies).

Private VLAN (port isolation): restricting switch ports (private ports) so they only communicate with a particular uplink.
