In the end though that ability will make users more productive and when security is integrated as it needs to be, it will help IT deal much more effectively with the heterogenous world that has applications everywhere, he said.

“Orchestrating the management systems of these separate networks is our next frontier,” Harrell said. “That’s where we want to go.”

While it is early in the 5G and Wi-Fi 6 evolution, 2019 will see development of that integration. According to a blog post by Harrell, this year will find carrier-based mobile connectivity (LTE and 5G cellular) and unlicensed nomadic networking, Wi-Fi 6, converge in two key areas: radio signal encoding and scheduling.

Both new wireless systems use the same method to squeeze more users and data into the frequencies they use, so each base station or access point can talk to more devices simultaneously, Harrell stated.

“Also, with WiFi 6, local wireless networking gets more scheduled, deterministic use of spectrum, he stated. "Unlike other versions of Wi-Fi, which use a randomized channel access mechanism, with Wi-Fi 6, a device can rely on being able to use the radio on a particular schedule (measured by the millisecond)." Scheduled access enables lower latency, battery consumption and also allows for greater density of devices, he said.

As for the impact of Wi-Fi 6 for enterprise customers, Harrell said that combined with its reasonable cost to deploy and maintain, it will prove an ideal system for indoor wireless connectivity – especially in areas with crowded access points.

 “Users on Wi-Fi 6 devices will see improved individual experiences. People in crowded areas that have traditionally offered hit-or-miss performance (waiting rooms, student lecture halls, meeting spaces, and so on), will have better experiences,” Harrell said.

Some devices that previously would only be connected by wired Ethernet will be able to move to wireless. “This will help drive innovation around high-bandwidth and latency-sensitive use cases that should really be untethered, like AR/VR, gaming, and video communications,” Harrell said.

As the number of performance-sensitive wireless devices goes up, enterprises will need new network intelligence to assure the best levels of service, he said.

“Specifically, Cisco believes that Wi-Fi 6 access points, and end devices themselves, must become sensors, collecting real-time performance and experience data that they stream to a new generation of analytic engines,” Harrell said. “This will allow for proactive and granular management of these increasingly complex environments.”

Cisco recently introduced the Cisco Intersight virtual appliance, an offering that allows Cisco Intersight users to gain more control over how their data is shared.

Intersight is a SaaS platform designed to help users connect systems like Cisco UCS and Hyperflex intelligence and best practices from Cisco, with the goal of lowering costs and simplifying operations. But for organizations with stringent security requirements, the new Intersight virtual appliance could make this platform more appealing. Here’s what you should know.

Benefits of the Cisco Intersight virtual appliance

The Cisco Intersight virtual appliance is made for organizations that have additional data locality and specific security requirements for systems stored on the edge or in traditional datacenters. In these cases, you may not be able to meet those security requirements with SaaS-delivered management alone. So the virtual appliance provides a single point of egress from your network so you can have greater control over what data is sent back to Cisco.

This can help users meet strict regulatory and compliance needs, especially those that require certain system details to be managed or maintained on-premises or within the borders of specific countries. While providing this level of security, the Cisco Intersight virtual appliance also gives users the ability to maintain access to all the SaaS capabilities within Intersight.

Nothing virtual about it: VR is red-hot in the app developers community

How it works

Basically, Cisco optimized all of the microservices within the SaaS version of Intersight to allow them to run within a VMware OVA, which is hosted on your own infrastructure. This setup used the same device connector technology embedded in UCS and HyperFlex systems so that your virtual appliance can easily connect to those services running in the cloud. Your virtual appliance can easily connect, but you get to change your settings to control what data from those services to Cisco.

This only requires a connection to Cisco and Intersight services for updates and feature delivery. Otherwise, you simply update your data settings and access those Cisco services as you would normally.

Cisco fixes gimme-root holes in HyperFlex, plus more security bugs

Cisco emitted on Wednesday a bunch of security updates that, your support contract willing, you should test and roll out to installations as soon as possible.

There are 17 advisories in all, including revised versions of previously issues bulletins, with six marked as high in terms of severity and the rest medium. The worst of the lot grants root access to a local attacker, closely followed by another that allows any remote miscreant in without authorization.

Here's a summary of the high-severity security blunders:

• CVE-2018-15380: Cisco HyperFlex Software Command Injection Vulnerability

A logged-in rogue user can execute commands as the root superuser without authentication. "An attacker could exploit this vulnerability by connecting to the cluster service manager and injecting commands into the bound process," says Cisco. "A successful exploit could allow the attacker to run commands on the affected host as the root user."

• CVE-2019-1664: Cisco HyperFlex Software Unauthenticated Root Access Vulnerability

A logged-in miscreant can gain root access to all nodes in a Cisco HyperFlex Software cluster without authentication. "An attacker could exploit this vulnerability by connecting to the hxterm service as a non-privileged, local user," Switchzilla explained. "A successful exploit could allow the attacker to gain root access to all member nodes of the HyperFlex cluster."

• CVE-2019-5736: Container Privilege Escalation Vulnerability Affecting Cisco Products

This is a patch for Docker's give-me-root runc hole, which we previously reported, that affects Cisco products. This is version 1.2 of an earlier advisory, with more Switchzilla gear now listed as being vulnerable to the privilege-escalation flaw.

• CVE-2019-1659: Cisco Prime Infrastructure Certificate Validation Vulnerability

An unauthenticated man-in-the-middle attacker can intercept, decrypt, and snoop on the SSL-encrypted tunnel between Cisco's Identity Services Engine (ISE) and Cisco Prime Infrastructure.

• CVE-2019-1662: Cisco Prime Collaboration Assurance Software Unauthenticated Access Vulnerability

An unauthenticated, remote attacker can access installations of Cisco's Quality of Voice Reporting (QOVR) service of Switchzilla's Prime Collaboration Assurance (PCA) Software as a valid user.

• CVE-2019-1681: Cisco Network Convergence System 1000 Series TFTP Directory Traversal Vulnerability

An unauthenticated, remote attacker can download arbitrary files from the TFTP service of Cisco Network Convergence System 1000 Series software, possibly resulting in the disclosure of potentially sensitive information.

The remaining medium-severity holes include a Webex Teams for iOS Arbitrary File Upload Vulnerability (CVE-2019-1689), IoT Field Network Director XML External Entity Vulnerability (CVE-2019-1698), Hyperflex Stored Cross-Site Scripting Vulnerability (CVE-2019-1665), and a Cisco Unity Connection Reflected Cross-Site Scripting Vulnerability (CVE-2019-168).

Interestingly enough, the Cisco Firepower 9000 Series with the Cisco Firepower 2-port 100G double-width network module can be crashed (CVE-2019-1700) by sending it maliciously crafted network packets from an adjacent subnet. This causes its FPGA, a chip that can have its circuitry rewired pretty much as desired, to lose the plot, and stuff the machine sideways.

"The vulnerability is due to a logic error in the FPGA related to the processing of different types of input packets," says Switchzilla. "An attacker could exploit this vulnerability by being on the adjacent subnet and sending a crafted sequence of input packets to a specific interface on an affected device."

That must have been an interesting bug to find and fix, we reckon. It was found while diagnosing a customer support query, we're told

Cisco downgraded by Morgan Stanley on slowing growth
Morgan Stanley lowers its rating on shares of Cisco Systems to equal weight from overweight, citing      slowing growth in the company's networking security business.
"Although Cisco is steadily executing on the Security opportunity we think the current pace is              unlikely to offset deceleration in the traditional hardware cycle," Morgan Stanley analyst James          Faucette says:


Morgan Stanley on Tuesday lowered its rating on shares of Cisco Systems to equal weight from overweight, citing slowing growth in the company's networking security business.

"Although Cisco is steadily executing on the Security opportunity we think the current pace is unlikely to offset deceleration in the traditional hardware cycle," Morgan Stanley analyst James Faucette said in a note to investors. "We therefore think it is a good time to step to the sidelines."

Faucette said his firm originally recommended Cisco as a company with an opportunity to grow meaningfully "as customers implement next generation IT infrastructures." Cisco's stock has climbed steadily since October 2011, adding 17 percent over the last 12 months alone.

"But our latest surveys suggest the pipeline for Cisco's Security sales amongst resellers is flattening," Faucette said
