So why does anyone care? I think this ad from the Determina Web site is interesting:
I've heard of an intrusion prevention firewall, a database firewall, and even a human firewall, but this is the first memory firewall. The technology has been public for about a year, but it's starting to make new appearances in articles like this.
Clearly Determina is following the standard start-up model.
- Invent product.
- Brand product to create a new market not filled by others, even though product is similar to others.
- Claim market leading product in newly created market.
In other words, a "memory firewall" is more commonly known as a host-based intrusion prevention system. I think I like the term memory firewall better than HIPS, since its use of the term "firewall" properly refers to a product that blocks access. Whether their implementation is better than other HIPS is beyond my ability to speculate!
I'm wondering if anything that restricts actions on a host should be called a host policy enforcement system (HPES) and anything that restricts actions on a network should be called a network policy enforcement system (NPES) While accurate, neither term is catchy nor easy to say. I see Tina Bird used PES to refer to Cisco NAC and Microsoft NAP in this article. PES is also associated with 802.11X.
