Ch. 5 – Securing Network Devices

Well, I didn’t get a second chapter done this morning but I had intentions to. I’m kind of laughing about this but we have had several issues today with enforcing non existent procedures and being unsure about next steps in projects and it sometimes seems as if there are some people in our department that are more interested in causing a fuss than actually getting work done and doing any kind of planning. This is not a surprise at all. Anyway, I’m trying to push for managed windows updates and have found clients on the network I can replace. I posted the info in teams and need to wait to hear back about it. Also today was turkey shoot day at work where you could win a free turkey by being good with like a rubber band gun or something. Not really sure. I got the calendar notice but didn’t exactly pay attention to it for some reason then got slightly sad when I missed it. Anyway, I’m also getting a super sick goth dresser delivered today that was on sale for like 55% off and appears to be a super nice bit of furniture. No idea how its being delivered but I’m hoping there isn’t much assembly time. Could go either way but regardless I’ve charged my cordless drill that ive been using all year on home ren projects and never once charged the battery. Lets get into these questions.

Not sure, this is cisco tech that I’m just learning about.

This isn’t really making a lot of sense but something as easy as a password does not require much CPU up time. However there are many many types of hashing and encryption. Im going to go with C because rainbow tables exist for common hashes lol

right…. not sure about that

I would assume B to be true here as it makes more sense but even in the process of hashing it may become clear what the algorithm is. It’s possible A is also true.

Kind of enjoying this Sec+ review. Anyway, not sure what the VTY is but I think its a safe assumption that that its Virtual Terminal Yes?

I’m going to say B is my best guess because I’m not exactly sure. It seems weird to dig into a packet that deep on a firewall but to be honest that sort of packet inspection makes sense.

B for sure and I would assume D as well as those have to be regularly updated. A I would assume to be done by traditional firewalls. Maintain a database of IP’s its communicated with.

Turns out I have A and B backwards. B seems more complex but apparently its been in use for a while. Interesting. Anyway, new Pope Hate track. Seems like the Pope is down a bit in online popularity at the moment haha

Ch. 4 – Security Architectures

It’s been slow going but you know, im studying. Sort of. Work has been somewhat busy and there is nothing else terribly exciting going on. Other than getting a new Dell AIO machine that’s 27 inches and has an amazingly fast processor. I did something on it that took 15-20 mins on my i7 m15 laptop purchased last year and it took like 30 seconds on this computer. I dont know if it had to do with SSD or the processor but I’m assuming both. Regardless, so far its amazing and has no issues displaying on my 28 inch monitor as well giving me a 27 inch screen and a 28 in screen. I also have been poking around in pro tools and trying to sort of learn it but I dont really think its going to work for me or really be super helpful. I haven’t spend much money on it. I bought like a 25 dollar copy of PT 12 on ebay. They offer a sub service and like other a trial period service so I probably did not need to “buy it” but regardless I’m having fun with it. I have a another copy installed. I also paid off last years furniture and got more of that this year. The payment is a little more than last year but the quality is much higher. I didnt really need a dresser but its super goth and perfect for my living space. It’s also 54% off and they had an open box deal on the only matching nightstand that was 40 dollars off so, ok. lol Anyway, its a year of paying off debt and eating cheaply. Not sure how much of my personal training contract is left but cant wait to be done with that. Let’s get into some questions here!

B

D, its worded funny though

a and b

d

I’m not familiar with this one. C?

A&C

B

Not sure what hes asking here. I’m only familiar with hosts on the subnet being assigned an “A” status

c?

Well, glad I got that security+ lol, Anyway, going to the gym for a short run and then maybe doing another blog posts. Kind of behind on these things but I’ll get them down.

Ch. 3 – Advanced IPv4 Access Control Lists

Well, haven’t been super active on this lately but like I said, as long as I can get this in the next calendar year, I am happy. So many things kind of going on. Mostly working on getting in shape and staying organized. That doesn’t sound like that much but it shockingly is. I could probably study more at work. That is a fact. Anyway, I got a reallly good deal on a 27 inch dell AIO machine that I bought yesterday and is arriving today. I should probably buy another SSD for it but still, the monitor is a 500 dollar monitor and its got a an 11th gen i7 in it. The video card is, not really even installed haha but I don’t really play video games so its fine. I mean, its absolutely for music production. Which I don’t make money off of and never will but it is fun. I mean, I really like making music and I’m good at it. I think I’m good at it and I have good taste in music. Obviously its not popular but I don’t really care. Stressful times though with that 18 months no interest situation.

Its kind of funny. You assume that images will scale no matter what size that you view the PDF at but that really isn’t true. these where at like 65% and they do actually look smaller. How that hurts peoples feelings, I have no clue and I’m not real stressed about it. Why anyone would be this stupid and purposelessly self centered, is beyond me. Like clicking the 100% button is not that hard. What’s it hurt? Probably some ones ego or ability to grasp reality.

The Assassination of Franz Ferdinand: The Archduke Who Despised Hungarians  - Hungary Today

Anyway, I looked this up and while it doesn’t implicitly state its the same thing as a regular ACL, that does appear to be mostly the case. Given the options E and F seem to be solid candidates.

The first part of this is a real kicker. I dont know what those numbers mean. I guess I’ll have to figure that out if I see it on a test prep question.

Same story here.

These really could be random numbers labeled access list but this one sources ports in the answer yet there are no ports listed in the answers. the eq is a thing but this isn’t given proper treatment.

A and C both seem plausible but C seems like a better choice.

No clue but it says choose two and C and D match so its probably that.

Humm I don’t think it would be in A and B and we are still real big on 2 answers. I’m going to guess the last two. Shot in the dark.

Well, that’s all im going to go into for now. The reason? Who knows. Obviously its all random information where we just do what ever we feel like to feel cool and acquire a sense of belonging by saying the other guys are the bad guys with absolutely no goals or reasons in mind. Other than to maintain our absurd sense of self importance while doing things and not thinking through them at all.

Ch. 2 Basic IPv4 Access Control Lists

It’s been a productive day and I’m rounding it out with study. Wrote some riffs to chop up for a beat. Really enjoying the new guitar. This strat thing is aaaaammmazzzing. I also recorded using a mic across the room and it sounded great. Honestly had less than an hour in writing and recording but given that its going to be just bits in a 4-5 min composition that seems like a lot of time. Until you realize that playing guitar is actually a ton of fun and song writing is a really interesting thing when you start to uncover layers and ideas and so forth. I took a drug test this morning. Confident that I should pass and had PT training this morning as well. Went over good. I kind of realized that my fitness level is much higher than most of the people in the afternoon and it seems insane to do the things that I’m doing these days around people who are where I was like a year ago. Basically I’m doing cross fit that’s like a ton of upper body stuff and cardio with ropes, burpies and stairs. I can do sets fairly quick with a lot of reps without tiring. Anyway, I guess I like to stay busy so here we are, writing a blog post after basically writing an entire doom metal song and recording it on top of every thing else.

hahaha my last name is Barnes. That’s funny. Probably a coincidence. I have zero idea what a standard ACL could be configured to do. C&D?

good to know…./flushdns

what the hell does “valid number mean?

No clue what this is talking about.

I would assume D

E?

This is kind of tuff. D is possible but I think its C but it could be A if pings first to last because its in that range.

Depends on the math we are using but I think its probably D

You know, i started with B but assumed that the .255 worked like a subnet ruling out all hosts addresses but its actually inversed.

I guess thats all for tonight. Here is one of my absolute favorite doom metal bands Gates of Slumber!

Honestly the records sound better but its still fun to see live shows. I saw them a few times but the first was in 2009 at this fest with a friend name phil lol great song title. … glad its fucking online.

Ch. 1 – Introduction to TCP/IP Transport and Applications

Life is really odd sometimes and people are super weird. This isn’t new information but it seems like life is extra weird in my case for some reason. I’ve developed this thing where I can cut people off really fast because I’m fully aware that I don’t actually matter to most people. Like my life doesn’t mater to them at all. Does that make any sense? Like sometimes people just want to interact with me for shit’s and giggles and bring nothing to the table but stress and not help pay my bills. Like sorry I’m not really interested in that and am happy to be alone. I don’t know why that is but regardless I really got to get cranking on this cert and I have been kind of lazy about it so its whatever. I mean, im not expecting a damn thing from anyone I interact with but a hard time. Just to be honest. I mean, there are circumstantial factors about my life that make it almost impossible to get ahead or to date. It’s ridiculous and I’m just supposed to be ok to be put in this position. Lol, anyway, I did get a full time job offer from work, so that’s really good and helpful. Anyway, I’m apparently back into cert mode so whatever.

The word application gets confusing but guessing D and E because A and C do not make sense.

BDFC? Encryption is not a TCP technology to my understanding. No idea what flow control is but it seems like it would be router based.

lol nice, routing is router based and A is right.

b?

I think that’s a frame but it could be a segment.v

B?

C/D

Well, I did get some stuff done this weekend but I mostly stayed at home in bed. I approve of my level of productivity. lol So much going on…
