The decker also gains +2 for Hot-Sim, but that's cancelled out by -2 for the Sammy being on a public grid. That's a dice pool of 12 vs. 10 (the Decker's 4 Intuition and 6 Firewall from Commlink). You are correct that this is a tough battle for the decker, but that's a 53% chance of scoring at least 1 Net Hit. Let's say he's smart and hacks the Wired Reflexes once before attacking. If the Hack is successful, then a one-shot to the Wired Reflexes is very doable. Assume the corp decker has a pretty good deck with a high rating of 6. With Decryption (+1 Attack) and Hammer (+2 Damage), he's got a Base DV of 9. On top of that, if he's running Mugger, his 1 mark will add 3 more damage for a base dv of 12. If he gets just one Net Hit (a successful attack), that's 13 damage.
The for the record, the example Spider I have been using is the "ELITE CORPORATE SECURITY LIEUTENANT" on page 384. Using both Decryption and Hammer his base damage could be as high as 11, but he lacks the mugger program. I think I quoted 8 before from someone else's post without verifying the math, and it probably lacked the software boosts. As an "Elite Rating 5 Lieutenant" his stats and gear may be a bit on the high end for the average facility, but there weren't any lower end spiders in the NPC section to use instead, and I wanted a set base of stats for this discussion.
As for the 12 dice pool, you're assuming that the off-site night shift Spider is within 1km of the facility. I suspect he's not that close, which means with only his Datajack for Noise Reduction, he's probably taking at least a -2 distance noise penalty, and possibly more, if he tried to do anything on the Gridspace instead of in the host. I figured 10 dice was a reasonable value, but it could be as high as 12, and is 14 if he's attacking a Decker in his host. This is why onsite deckers are more effective than remote ones, but it also means the shadowrun team can shoot them and steal their deck, which costs half a million dollars new. Honestly, if I was pulling a run a facility where the spider has such a nice bit of hardware, I'd be tempted to run a trace on him, and if he was just 1km away, he might be worth visiting later expressly to collect his nice deck.
As for marking the sam first, to get bonus damage on a dataspike, keep in mind that marking the Sam's gear for extra damage is also a dice pool of 8-12, depending on distance noise, vs 10 on defense. If he does so with a Brute force, he's alerting the sam to the attack if he succeeds. If he does so with Hack on the Fly, he risks being spotted and marked if he fails. Either way there is about a 50% chance that taking the time to mark the target will alert them to the hack attempt, giving them a chance to turn off their wireless.

I don't believe slaving a device gives any benefits to Damage Resistance, only defense tests, which are expressly different from Damage Resistance tests.
I thought damage resistance tests were a kind of a defense test, but if what you say is true, it very much changes my mind about the safety of devices from enemy hackers/spiders, as it makes it much more likely that a device can be bricked in one average attack instead of two to three average attacks. What are the chances the book clarifies this?
Page 358, PANs & WANs says: "When configured in this way, every device uses the Rating of the Master instead of its own when doing any sort of test." This particular line is a bit of a mess, as it would mean that a Commlink slaved to a Deck suddenly gets to use Attack and Sleaze ratings... which shouldn't work. Page 233 says the benefits of a PAN are only for Defense Tests. Defense test are never explicitly defined any more than Damage Tests are. Is a Damage Test a Defense against Damage?

as i pointed out, it's very good odds that in case of emergency, the facility you're in can bring in at least two hackers in addition to the on-duty hacker (assuming that a shift is not 12+ hours... if that is the presumed shift duration, you're still looking at two hackers total, each of which can still fork to brick two devices at once).
You and I have a different interpretations of how corp facilities handle their security. I've seen your argument that the average corp facility should have multiple spiders on hand at all times and the ability to call in more quickly at a moment's notice. I disagree.
First of all, the multiple Spider and rapid on call decker squads are not described or implied in the book, nor are budgets for facilities that gives anyone the authority to claim it's a reasonable expenditure.
To my view, which is to say my opinion, corps are not likely to spend that kind of resources on most of the facilities. A corp has thousands of facilities and if each of them is spending the kind of money you're talking about on matrix security, that's a MASSIVE outlay of cash on something that doesn't contribute to the bottom line. A good deck and someone trained to use is large expense, far more than a security guard, on par with an attack helicopter. Corporations exist to make money, not be secure. They won't throw any more money at an issue then they can justify, and often times far less than they probably should. If a facility isn't getting attacked
regularly, I doubt the exec in charge of it or the his regional boss, or the accounting department, etc is going to justify laying out so much money
just for matrix protection. It's the same reason why even the "elite" corporate security guards on page 384 have rating 4 commlinks instead of rating 6. Hell, even the elite special forces only have rating 5 commlinks.
I suspect your average corp facility, which I define as one not working on a highly advanced project, black book project, or military gear, might have 1 spider on duty during the business day, possibly even physically in the building. He'd be running matrix security during the hectic day as people come and go, files move around, and deliveries and visitors show up. He might possibly acting as a kind of system admin as well, helping to deal with file sharing issues, etc within the Host.
Outside standard business hours, the building and host is much less active. I suspect instead of paying a small army of people to sit around waiting for a possible shadowrunner incursion (which I don't think happen to a
particular facility more than one every few years at the most), the corps have a single on-call spider assigned to a group of hosts in their region or division of their particular corporate subsidiary, spending a portion of his shift in each host, checking in on things and making sure there is no evidence of a hack or break in, but mostly relying on the system's impressive firewall, the active Patrol IC, and the physical security measures in the facility itself. A single spider maintaining the status quo in 6 sites is a
lot cheaper than 1-2 in each site with 6 more on call at all times, and in my (real life) experience, most corporations pick cheaper over efficient 9 times out of 10, especially when dealing with divisions that don't
directly contribute to the bottom line, and deal with risk of possible future bad things vs spending a lot of money now and maintaining a force of well paid people that do very little most of the time (as they are waiting to defend.) Security doesn't produce products or make sales, so most facilities would throw "enough" money at it to be reasonably secure, not as much money as it takes to be completely secure.
That means the Spider may not even be in the Host when the players arrive, and likely wouldn't show up unless an alert is trigger, although he could get their quickly. It also means he's basically alone, and that even if he did have a friend to call in, it's probably a spider from another series of facilities farther away, and thus racking up larger noise penalties... or he's got to wake up one of the day shift spiders, which means it may be minutes or longer before they show up.
Higher security facilities are much more likely to have on hand spiders, 24 hours a day, and possibly access to multiple hackers, even if some of them are just on-call backup.
I think this is basically how matrix security was defined in 4th edition, and it matches the security descriptions of Border crossing hosts in the 5th edition Coyotes book, where only Very Hard border crossing rate an active Spider in the system most of the time.
