Establishing a plan to protect your Network

Establishing the perfect network security plan for any organization requires a number of tools and solutions (just visit https://www.fortinet.com/products/management/fortimanager and learn all about it). In this post, I want to discuss one of those tools distributed trust. Distributed trust is a system for securing the Internet of Things, where we can use open source tools to make it happen.

Cyber Security – Not Just IT - Brown Rudnick

Before we can get into how distributed trust works, we need to understand what exactly a trust graph is. In order to understand distributed trust, we need to think of trust in the context of a graph. A graph is a tree structure with nodes and edges. An important aspect of a trust graph is that trust is represented in a form of a graph and not in the binary sense. For example, in the following trust graph, we see that the group of nodes has a higher degree than the edges of the graph.

To make distributed trust work, you need to create trust relationships between nodes. A graph can’t just represent trust relationships without also representing the information they contain. In a distributed trust network, we need to have nodes with permission to pass information between each other. In the next part, I will discuss some common models for distributed trust that you can use.

On the topic of permissions, the notion of privilege-based cryptography is a great example of a model for distributed trust. The logic of how to make it work is similar to how a distributed graph works. When two users in a centralized network have the same set of permissions, the network is vulnerable to a Denial of Service (DoS) attack. When two users in a distributed network have a higher degree of permissions on each other, they can coexist more efficiently in the network. The mechanism for this is called BGP.

One model of how to design distributed trust using BGP is called the Cloud VPN. It doesn’t rely on any of the above mechanisms, but instead utilizes the capability of the L2TP (Left-to-Right Tunneling Protocol) Layer 2 protocol to enable flexible configurations for users and gateways. Cloud VPNs are a great tool for implementing distributed trust, but you don’t have to build your own VPN for a distributed trust solution to work. Most companies that create distributed trust tools are using Cisco IOS, so IOS makes for a great BGP solution as well. If you need a business phone and internet connection that’s reliable and secure, visit sites like https://www.eatelbusiness.com/business-phone/ and check their packages.

In the case of BGP, you make one endpoint (the “gateway”) to serve the global Internet, then you set up routing rules in a routing protocol like GRE. In a BGP network, the client sends its routing information to the gateway and then the gateway determines how to route the information to its destination. In the case of BGP, we cannot see any other information about the individual users or gateways in the network. Because BGP is a protocol that directly communicates directly with other networks, you can fully trust that the individual processes that create routing information in the network (e.g., routers) don’t try to send the information in the wrong way, especially if they only have data to transmit. If you do, you might lose data. Be sure to backup before doing the process. Visit sites like venyu.com/colocation/ to know how you can protect your data.

mixtape: one shiny summer

it’s been a few months since the last one. this is a collection of shiny sounding summer beats. electric and swerving. back to the basics of pretty instrumentals, trip hop, smoky bass, and sultry vocals. best served at an afterparty… or the long walks home at stupid o’clock after a messy but fulfilling night.

Aside

we generate our own electricity.

there are few things more fun in life than talking about the universe with the pretty brunnette on the exercise bike beside you. i usually have my mp3 player with me, but i forgot to charge it last night. the battery died about 20 minutes in. i see her most mornings, but never on the bike — always on the treadmill or elliptical. we’ve never really spoken aside from the customary greetings. probably the magical hand of fate at play here.

i like it when a culmination of coincidences make some it seem like this is the way things are supposed to be. there’s nothing wrong smoke and mirrors occasionally.

she wants to take me ‘for tea’. i told her that sounds a little sophisticated for me. she said there’ll be lots of honey — not that i needed any more convincing.

the best morning of my life.

unless you’re warning me about the zombie apocolypse, never ever bang on my door to wake me up. use the buzzer. call me. fire off a text. never put fist to door — EVER. i’ll be pissed. and when i open the door, don’t stand there and give me the “what?” look. speak your business. i care nothing for neighbourly pleasantries. it’s quarter to 7 in the fucking morning asshole, and i barely had 4 hours of sleep. thanks.

let’s compound this with the fact that once i cross that 90 minute sleep threshhold, once i am woken, there is no way i am going back to bed, so here i am sitting at quarter to 7 in the morning, trying to think of an eloquent way to express my rage. but instead, i’ve decided that complaining is the best route to take. so here goes.

at work, there’s a girl who’s under the delusion that she’s in love with me. she had been a constant source of consternation for my last girlfriend (who ended up being the possessive and surprisingly dangerous jealous type). sometimes shows up at work cradling tupperware containers, filled with really delicious home-cooked food — one of the more tragic rarities in my life.

she is very, very, very sweet. and very pretty. and she’d be a great mother to children. she was raised on a farm with 3 older brothers who all play hockey. but.

she is very, very, very boring. since hiring her just before christmas, i don’t think i have ever had a conversation with her that lasted for more than 10 minutes. so i have no idea why she would even like me. but my friends say i’m crazy, and i need to give her a chance.

so i did.

we went to a book fair and wine festival last week. still boring.

i have a friend who is interested in a girl who can be most accurately described as somewhat sketchy and rather flimsy. why guys get interested in these types of women, i’ll never understand. ok that’s a lie: i’ve been enamored with the type before. when i was younger. and my standards were non-existent. but these unions almost always end in bloodshed. or at the very least, tears and terrible poetry.

first of all, you shouldn’t have to out of your way to convince a girl to like you, especially if she’s the type that has no issues fucking with your head by pitting you up against some competiton. we aren’t in camelot anymore. also, if she always talks to you about how ‘she needs to breakup with her boyfriend’, that means it would be nice but it’ll probably end up taking a while before she’ll ever muster enough backbone to go through it.

do you really want to expend all that energy on a girl who, at the end of the day, is going to be sleeping in the same bed with a guy she just spent the last 6 hours bitching about?

you deserve better.
