Experts: IDS is here to stay

Imagine my surprise when I read Experts: IDS is here to stay:

Conventional wisdom once had it that intrusion prevention systems (IPS) would eliminate cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 need for intrusion defense systems (IDS). But with threats getting worse by cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 day and IT pros needing every weapon cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365y can find, cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 IDS is alive and well.

"IPS threatened to hurt cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 IDS market but IDS is better equipped to inspect malware," said Chris Liebert, a security analyst with Boston-based Yankee Group Research Inc. "IPS specializes in blocking, so each still have cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365ir own uses, and that's why IDS is still around."

IDS is now part of a larger intrusion defense arsenal that includes vulnerability management and access control technology. In fact, one analyst believes standalone IDS products will still be in demand five years from now while IPS technology will likely be folded in firewall products.

"In cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 long term, I do not think IPS devices will remain as separate products," said Eric Maiwald, a senior security analyst for Midvale, Utah-based Burton Group. "We see this happening already. All of cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 major firewall vendors offer some amount of IPS functionality in cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365ir products. At cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 same time, cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365re is much firewall-like capability in cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 IPS products."

IDS products will probably remain as separate devices because of cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 need to monitor happenings on a network and monitor actions of ocá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365r policy enforcement points, he said.
(emphasis added)

Wow, imagine that. Anyone who's read my books or this blog for any amount of time knows I've advocated this position for years. What's an "IPS" anyway? It's a filtering device, aka "firewall." What's an "IDS"? It's an attack or incident indication system. The two functions are completely different and should be separate. It's too late for me to say any more now, but I wanted to note this article before I forget I read it.

Well said-- I was actually just having a conversation with some co-workers making that exact point: IDS and IPS are complementary technologies, with different goals.

I think this is to directly confront cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 June 2003 Gartner report / statement that "IDS is dead". Why it took four years to do so is beyond me and maybe IDS just needed more time to figure out what it wanted to be when it grew up.

Still many have been sold on cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 IPS "Solution". To cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 point where you really have to sell cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365m on cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 idea that some things shouldn't be blocked.

Riddle me this, how is Pescatore still a "security player" after his moronic statement, which IMO was geared only towards one purpose? Getting companies to drop dollars on IPS.

As a technologist, I am accustomed to experts like Gartners lecturing me on how "customers don't buy technoology, cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365y buy solutions". Well, it turns out that cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 experts can be wrong too.

Customers don't just buy solutions, cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365y buy solutions that fit within cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365ir job description.

Gartner had created tremendous uproar with cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365ir original assertion which is probably why cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365y did it. But cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365y were wrong not because IPS is not viable but because IPS and IDS fundamentially sell to two different set of customers.

Richard was correct in pointing out that IPS belongs to firewall and will be part of cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 "networking" infrastructure whereas IDS will always remain part of cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 "monitoring" infrastructure.

IPS and IDS will co-exist because cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365re are two separate job descrptions.

Just because you bought an IPS doesn't mean you have to enable cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 blocking functionality. You can enable blocking only for certain signatures or severity levels and turn it back off whenever. Why cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 debate over which is better? Also, cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 nice thing about separate devices with a dedicated purpose is you are not tied to a single vendor and cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365ir "all-in-one" product that may be crap. I just don't see how security collapsing into cá cược thể thao bet365_cách nạp tiền vào bet365_ đăng ký bet365 switch is a good thing. Do you really want to be force fed integrated Cisco IPS? If that happens I wouldn't be suprised if we are talking about why would should be keeping things separate again in a few years. Could this be a cycle? Could this be planned obsolesence? *dripping with sarcasm*
