Migrating to CCIE Security Lab Blueprint v3.0

In this post we will give a brief overview of the upgrade path from CCIE Security v2.0 blueprint to v3.0. First off all, let’s start with the good news to everyone who was preparing using the old blueprint: most of things you have learned are incorporated smoothly in the new blueprint. Basically, the only thing to forget is your VPN3k configuration skills :) Everything else either remains the same or experiences an “incremental update”, like LAN-to-LAN VPNs with IPsec VTI interfaces. Let’s quickly review the changes made to the hardware and how they could potentially affect you.

• Removal of the PIX and VPN3k devices, which is natural as both are EOL and EOS. Therefore, forget all about VPN3k menu system and enjoy the simpler topology without the PIX ;) However, to some people, getting a PIX is more affordable than getting an ASA. In this case, remember that the latest software release supported by the PIX is 8.0(4) (not the 8.1) and you cannot configure SSL VPN on PIX. Still, you can practice almost 90% of all the firewall features using the PIX.
• Change from the Catalyst 3550 to 3560 models. From the security features standpoint, nothing has seriously changed. You can even continue using the older 3550 model, as they are probably cheaper to get nowadays.
• The so much awaited upgrade from IOS 12.2T to IOS 12.4T. First of all, this might require a change in the hardware platforms you are using. If you were using non-ISR or non-2600XM routers, you will need to change the hardware platform to at least 2600XM with full flash/RAM memory (to run the Advanced Security feat. set) or the 1841 ISRs. Note that using Dynamips you can play with all 12.4T features without getting your hands around any real gear. Secondly, 12.4T introduces a ton of new features, as compared to the dusty 12.2T. However, it’s not that scary as it might look like. Most of the new security features relate to IOS PKI, some AAA enhancements, bunch of advanced VPN topics and infrastructure security. Probably, all the most notable features are VPN/Firewall related: IPsec VTI, WebVPN/SSL VPN support in IOS, DMVPN Phase3, GET VPN; Zone-Based and Transparent firewall, CBAC enhancements. Later in this document we will see those features detailed as the upgrade list of the new SC VOL1 labs.
• ASA software upgrade from 7.x to 8.x. While is a major version jump, it does not imply the huger change in the CLI as it was with the upgrade from 6.x to 7.x. There is quite a bunch of new features in 8.x code (you will see the list later) but most of them are minor ones. Most likely you will enjoy things like Dynamic Access Policies, LDAP Authentication and Authorization, Secure Desktop Enhancements, EIGRP Support (who needs that?:), Transparent Firewall NAT and Traffic Shaping. However, if you are solid with the code version 7.x you wont face big problems mastering the new topics.
• IPS software upgrade from 5.1 to 6.1 and the platform change to 4240. The catch here is that IPS v6.1 does not support many older IDS/IPS appliances, such as 4215 or 4235 and getting a 4240 might be expensive. However, there is some good news still. The CLI has not changed as much as it did with the 4.x to 5.1 upgrade, and all your 5.1 knowledge remains valid and up to date. The most notable new features are Virtual Sensors, Anomaly Detection, Threat Rating and the new IPS Manager Express. If you are OK with doing all your configurations via CLI, you can stick with IPS v6.0 which you could run on the older platforms (4215, 4235) as there are just minor differences between 6.0 and 6.1 (mostly related to IPS Manager Express). Probably the best news is that the old 4215 platform could be successfully emulated in VMware.

Now, let’s look at the v2.0 to v3.0 upgrade path that you can take with out products. Below is the list of the VOL1 technology labs. You can see the outdated topics being deleted and the new topics (which are being developed) highlighted. Naturally, many older labs remain perfectly valid for the new track, and you can continue practicing them while waiting for the upgrade being released. We also decided to keep the NAC labs, even though NAC is not on the current blueprint, mostly because it gives you a perfect scenario for advanced ACS configuration. Of course, if you own our current v2.0 products, you will receive the v3.0 updates free of charge.

The VOL2 upgrade will be taking place in parallel with VOL1 updates. What you should expect is removal of the VPN3k and (probably) PIX and the changes to the approximately 30% of the material. Many of the existing v2.0 tasks will remain the same, so you can practice the existing material, ignoring anything related to VPN3k (but not the PIX, as many of the PIX features remain unmodified in the new blueprint).

Good luck with your studies!
