A Peek at Snort 3.0

Next-generation of open source platform will be more than just IDS/IPS

The wildly popular open source Snort intrusion prevention technology is getting a major makeover.

Marty Roesch, who wrote the first version of the software nearly 10 years ago, has rewritten the software from top to bottom in the next-generation Snort 3.0 release, due in beta next month and early next year in its final release.

“Snort 3 [makes Snort] not just an IDS/IPS anymore. It’s for building arbitrary network security operations and other technologies atop it,” says Roesch, who is also founder and CTO of Sourcefire. Snort 3.0 will serve as a network traffic analysis platform as well, according to Roesch.

Roesch says the new platform is a more streamlined, scalable, and faster system that’s more adaptable to today’s networks. “Snort 3 is heavily multi-threaded,” he says. “It has IPv6 support, and MPLS support, built in,” for instance.

Snort 3.0 is built to run any type of traffic and to handle any type of network security task, he says. “If you want to implement a firewall in Snort, you can do that," and it could encompass change and anomaly detection, for instance, as well.

One of the key improvements in the new Snort is that it’s less susceptible to IDS/IPS evasion or bypass attacks, where attackers sneak past the devices. Roesch says Snort 3.0 doesn’t have to be manually fed rules: “You teach Snort what the network looks like so it can defend itself accordingly. It tunes itself. My end goal is to have a self-tuning protection engine.”

The new Snort 3.0 engine also supports more hardware acceleration: “You’ll be running Snort on bigger and faster networks, so in version 3 we made it easier to add hardware acceleration to it,” he says.

And yes, it will be backwards-compatible with Snort V2. Roesch says the open-source beta of Snort 3.0, which will be released next quarter, includes a Snort V2 engine module running atop the Snort 3.0 platform. That will allow Snort V2 users to more easily get accustomed to the new version, he says. “Snort 3 is going to be an upgrade,” Roesch says.

    CVE-2020-27673
    PUBLISHED: 2020-10-22
    An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. Guest OS users can cause a denial of service (host OS hang) via a high rate of events to dom0, aka CID-e99502f76271.
    CVE-2020-27674
    PUBLISHED: 2020-10-22
    An issue was discovered in Xen through 4.14.x allowing x86 PV guest OS users to gain guest OS privileges by modifying kernel memory contents, because invalidation of TLB entries is mishandled during use of an INVLPG-like attack technique.
    CVE-2020-27675
    PUBLISHED: 2020-10-22
    An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. drivers/xen/events/events_base.c allows event-channel removal during the event-handling loop (a race condition). This can cause a use-after-free or NULL pointer dereference, as demonstrated by a dom0 crash vi...

    PUBLISHED: 2020-10-22
    Velero (prior to 1.4.3 and 1.5.2) in some instances doesn’t properly manage volume identifiers which may result in information leakage to unauthorized users.
    CVE-2020-15680
    PUBLISHED: 2020-10-22
    If a valid external protocol handler was referenced in an image tag, the resulting broken image size could be distinguished from a broken image size of a non-existent protocol handler. This allowed an attacker to successfully probe whether an external protocol handler was registered. This vulnerabil...
