I'm the auditor and will be doing a network audit in an area I'm new to and my manager wants me to do some self study / practice. What you need are configs. Adventure Quest Worlds Trainer Download Free. Audits are about ensuring that configuration matches requirements, not design or effectiveness. Things like, is AAA enabled, or is there an ACL restricting SNMP access?

You don't need access to the gear to answer those questions, just see if you can get the customer configs well in advance of the audit date, like 2+ weeks out. Or see if someone else at your company has configs from a previous audit that you can review (the security guy in me says that's bad if they do, the person who lives in the real world is sure that they still have them). I'm the auditor and will be doing a network audit in an area I'm new to and my manager wants me to do some self study / practice. Hooooo boy.this is going to implode in spectacular fashion, but in order to help out: go to cisco.com, and search on the following topics: enabling AAA via SSH disabling AAA via telnet how to verify the above Where and how implicit denies take place in an ACL why and how sometimes what looks just like an ACL really has nothing to do with explicit traffic filtering (which leads to) determing why and where a specific ACL is applied (it is an ACL? A routing filter? An encryption domain identifier?) how a wildcard mask differs from an ACL, and where it may be applied from a security perspective how logging works, and how to export logs to an aggregator how password encryption works in IOS the difference between login and enable modes and.well.jeez.there's a LOT that an auditor should know, but if you've never touched IOS before, the questions you're asking are going to be met with a blank stare and 'wut?'

From an auditing standpoint, familiarity with the hardware would be sort of amazing if you showed up like that. From a practicality standpoint, that is a distant concern compared to basic bullet points you need to know about basic IOS hardening and network security concerns. Like 10 years ago, NSA put out a Cisco router security guide that resulted in a lot of new default settings for cisco routers and stuff so the defaults in modern equipment and software is a lot better than it was. But you still need to know what to look for to make sure people haven't receded on those issues. That is just a generic starting point. Security and auditing concerns for actual network design and implementation are pretty vast and complex.

It's good that you will have somebody more experienced with you, sounded like a train wreck in waiting before that. There's enough difference between the skillsets used in auditing and operations of networks that it isn't crucial to have that much hand's on experience, but it does help to have been on the receiving end so you know which question to ask and what practices are the most common. Before I got my CISSP and before I started doing auditing work I had about 6 years of operations and being responsible for the operations groups. Download Winamp Untuk Laptop Toshiba more. That came In handy since we were also looking at the design too, besides the normal stuff with regards to economy, hardening, documentation, processes and so forth. But IMO I would say that what you want if you are doing pure auditing is a good grasp on the technologies involved more then product specific knowledge. Especially since it's quite probably you will come across a variety of different setups and brands, not to mention that many brands have just a slightly different way of achieving the same underlying service compared to other brands.

Although it helps to have been using and be familiar on a couple of products and then build from that. And Cisco is a good way to start since they are readily used and many of the other products can be pretty cisco'esque at times.

I would suggest that you look at what Frennzy posted for a start. And in reality, after that you might just be better served to continue with getting a few good books on networking and operations and then a couple of hours with a good network-engineer/architect instead of 'just playing around' with a router unless you have some very specific goals you want to accomplish. From an auditing standpoint, familiarity with the hardware would be sort of amazing if you showed up like that. Amazing, but useless. Here's how an audit goes: Auditor: Does your device have X configured? Customer: Yes A: Let me see C: A: Does your device have Y configured? A: What is the reason for that?

C: There is a mitigating factor A that negates the vulnerabilities. A: Very good. How about Z, is that configured?

A: What is the reason for that? C: Due to factor B, this has not been implemented.

A: What plans do you have to correct this? C: Within the next 90 days, implementation of Z will be completed across all devices. A: Very good. From a customer standpoint, I don't expect or want you to have a good understanding of anything except your checklist, since you're just checking boxes off, but I do expect you to know your limits lest you question every answer I provide even when you know nothing about what you are asking. From an auditor's perspective, I don't expect you to have a good understanding of anything except your checklist, since you're just checking boxes off, but I do expect you to know your limits lest your endless series of questions scare the customers off so that they go to another auditor for a more benevolent rating. Damned if you do, damned if you don't Seriously, you don't need to know much beyond what the checklist is asking.

For example, 'Is remote telnet access disabled?' Technically, you need to understand the commands required to enable or disable telnet (depending on device defaults). Very simple, because there is really no leeway to either side - it's on or off. Now, take something like, 'Are shared logins disabled?' Technically, very easy - they are or they are not, depending on the device type. However, the real point of this question is whether or not individuals are properly authenticated, authorized, and their actions accounted for. Nearly all devices will allow individual logins, but it may not be feasible - a device may not support remote authentication (or their network will not, or their device is not compatible with the remote auth infrastructure they poured money into, etc.), which means if the customer has 200 devices and 20 admins, they have 4,000 user/pass combinations to manage.

Or a single shared account or two on each device. One is realistic, one is not. If remote access to the devices is restricted to two servers (production and DR) that do support individual logins and that have significant auditing capabilities, and the remote devices log all access and commands, that may be the closest the customer can come to 'Are shared logins disabled?' For a particular device type. That's the stuff you need to know, not the intricacies of the software. In addition to asking to see config files in advance, it would also be also very useful to ask if there is a published internal doc detailing the design/security Best Practice docs. The reasons are: 1) Different companies have different views on acceptable security practices (e.g.

My old company disables Web frontend on all IOS devices, but I know other companies do use them) 2) Check if said config(s) sent to you adhere to the published Best Practice doc (and for you to understand what some of those IOS commands do) 3) Force the clients into mad scramble and come up with a Best Practice doc (or update their existing ones), if they don't have one already. The problem with having people scramble for said documents are at least twofold. First thing would be that if they don't have then already, it means they either don't document what they practice, or neither practice, nor document such procedures. The second would be, if they scramble for the document, how big is the chance they will actually take the document and procedures into practice?

Depending on what the audit entails, it might just be a compliance thing towards a certain standards, or a more loose one, but if it's a deeper variety, a good audit should at the least do a number of activities together with the report that would capture such practices and detail recommendations for doing something about it, including long-term viability. And depending on how large the company is, this generally is presented to at least the CIO and often the CFO if it also deals with parts of the company economy. Then if they choose to disregards such things, then shame on them, but that would probably stand out if something actually happened as a result of disregarding said recommendations/practices.
