Look for conversation about weak ciphers, vulnerabilities like Heartbleed, BEAST, etc. It’s not necessarily crucial that they remember every themed vulnerability and the exact specifics, but they should know what the issue was, why it was a problem, and what the fix was.
Clipper was supposed to go in all kinds of things – phones, modems – but it included key escrow, and so everyone despised it. This may soon change with the rise of VOIP and the understanding that data in progress across the Internet is insecure. But it’s entirely arguable that the government was right in the mid 1990s when it said that deploying Clipper would enable greater general security for the masses. Certainly, nothing has arrived to do replace it. Besides key escrow, the other big crypto issue of the mid 1990s was the Clipper Chip, a government effort to create a standard for strong cryptography. But had Clipper been deployed, consumers and businesses would in general have far more secure telephones than the wholly insecure ones they have now.
Unlike traditional IPSec encryption solutions, GET VPN uses the concept of group SA. All members in the GETVPN group can communicate with each other using a common encryption policy and a shared SA and therefore no need to negotiate IPSec between GMs on a peer to peer basis; thereby reducing the resource load on the GM routers.
What you don’t want to hear is, “I get enough computers when I’m at work” I’ve yet to meet a serious security guy who doesn’t have a considerable home network–or at least access to one, even if it’s not at home. So if he’s got multiple systems running multiple operating systems you’re probably in good shape. Good answers here are anything that shows you he’s a computer/technology/security enthusiast and not just someone looking for a paycheck.
Forward Secrecy is a system that uses ephemeral session keys to do the actual encryption of TLS data so that even if the server’s private key were to be compromised, an attacker could not use it to decrypt captured data that had been sent to that server in the past.
This insures that the GM’s are not repeatedly re-registering to a KS that has not yet created a new TEK according to the GM’s assumed larger registration window. ● The coop Key Servers should have the same IOS version and the same GETVPN configuration. The recommendation is to upgrade the KS first followed by upgrades to the GM. Beginning with 22T, the KS and GM may use a longer registration window that is automatically calculated based on the TEK lifetime.
Adjust expectations according to the position you’re hiring for. Nonces required by the server for each page or each request is an accepted, albeit not foolproof, method. Again, we’re looking for recognition and basic understanding here–not a full, expert level dissertation on the subject.
So instead we generate tiny amounts of noise (the “seed”) and use it as a key in an. Their server software is FIPS certified, and the server software includes Dual_EC_DRBG. That it refuses to generate. All the common RSA moduli out there in the wild: we don’t know.
(and being able to differentiate them) is important for a security professional. Ask as many of these as you’d like, but keep in mind that there are a few differing schools on this. Just look for solid answers that are self-consistent. Knowing basics like risk, vulnerability, threat, exposure, etc. As weak as the CISSP is as a security certification it does teach some good concepts.
Re-registration should happen only if the rekey fails. Test the control plane: Configure few GMs initially to test the registration and rekey process. Because of receive-only mode the GMs will not encrypt any traffic. Verify if the registration is happening fine and also wait for some rekeys to happen. Validate using show commands, that rekey is happening fine and the GMs are not trying to re-register.
A VPN (virtual private network) creates a secure, encrypted tunnel through which all of your online data passes back and forth. Any application that requires an internet connection works with this self hosted VPN, including your web browser, email client, and instant messaging program, keeping everything you do online hidden from prying eyes while masking your physical location and giving you unfettered access to any website or web service no matter where you happen to live or travel to.
Sadly this is not yet understood by most interviewers and HR departments, and they’re still stuck in the mode of asking magic questions and looking for their favorite pet answers. The process has been shown to be highly biased, with interviews basically looking for people who fit their particular model of good (which usually matches something like themselves).
