comment Does dual boot hurt security?
Caveat: Encrypting your partitions, in most implementations, DOES NOT fully prevent attackers from modifying data on the encrypted disk. Any disk crypto that runs in CBC mode will be vulnerable to block-level xor malleability.

comment Effect on PCI compliance of not checking SSL certificate?
It's probably also worth getting in touch with the PCI Council and mentioning this. You might be one of the first to object to this request, and others may have just gone ahead with it.

comment masking credit cards PAN with zeros
@Timee That makes no sense at all; it's like saying having a database of every number from 0000 to 9999 violates PCI because you're guaranteed to have someone's PIN in there.

comment How does stored procedure prevents SQL injection?
@AnanduMDas No, that's not necessary. The database server, in a traditional string query, has to parse out the query language and data itself. This is why we have to sanitise the data, because it's ambiguous and could be mistaken for query language. When the two are separated out as part of the protocol (i.e. the query string and the data fed into it are split into separate sections of the packet), the data doesn't need to be sanitised because the database already knows that it's data, and won't treat it as query language.

comment Can't I forge an SSL certificate?
@JavaIsCool Browser updates and OS updates. Here's an example of an MSKB hotfix to deploy new root CAs.

comment Can't I forge an SSL certificate?
@raz 10-30 years is a more accurate range. Most are around 20 years, from looking at my TRCA list.

comment Can't I forge an SSL certificate?
@JavaIsCool To an extent, yes. Operating systems usually push out updated root CA lists in updates (e.g. Windows hotfixes) and browsers usually ship them with updates. Revocation of compromised or replaced certificates is achieved with Certificate Revocation Lists (CRLs) and similar mechanisms.

comment Four-factor authentication
@user2813274 Except George Washington's account would be long closed and locked, and your example has nothing to do with time locks in this context.

comment Is it possible to Spoof a TeamViewer ID?
Windows Server 2007 isn't an operating system. Did you mean 2003, 2008, or 2008 R2? ;) (not that it really matters)

comment C++ memset() memory overflow
@Mark It's absolutely on topic here. Whether someone could answer it better elsewhere is irrelevant. In these situations you can advise OP to ask over on another site, because they'd have better expertise, but that's not a valid reason alone to flag something to be closed as off-topic.

comment C++ memset() memory overflow
@Mark Ah, yes, so it does - it's a local scope instance. Blame my lack of coffee this morning! Rather odd that this is flagged, then.
