Todo o mundo SD-WAN should provide a unified at-a-glance view of your network topology, including registered and online appliances. For visibility, it should offer continuous automatic monitoring of network events, site and tunnel status, as well as providing report-based usage and availability data about your overall network, specific sites, servers, all applications and users.
Truly integrated tools – not a third party add on – can provide you with visibility end to end—all the way from the end user to the cloud, as well as instant and perfect visibility into the quality of every available path.
How Does SD-WAN Help Keep My Network Secure?
Security needs to be built in to the SD-WAN design—not added later in response to security breaches. Centralized support for embedded security, firewalls, access points and switches should help simplify and consolidate the overall management of equipment, especially at the branch and other distributed locations. Check for security that complements and integrates with third-party CASB or on-premises firewalls.
Security rules should be part of the policy and easy to implement, deploy, manage and change universally throughout the system—without any error-prone command-line interface (CLI) configuration.
The centralized, secure, global management system based on a single global policy should automate services and be easily changed for rapid response to changing conditions or new needs. User identity-based control provides an easy and intuitive way to define network access. Be sure you can identify users by name, roles or job functions. |

Todo o mundo Cisco has patched a clutch of high-priority vulnerabilities in its SD-WAN routers and their management software that admins will want to apply as soon as possible.
SD-WAN is a technology that allows large companies to manage different types of Wide Area Network (WAN) communications links such as carrier MPLS, conventional broadband, and mobile 4G as a single virtual entity.
Making SD-WAN work requires specific routers that support it, spread out across the WAN, as well as management software to interact with this infrastructure. It is this software that is vulnerable.
There are five CVEs in total, three of which are rated high, including one, CVE-2020-3266, given a CVSS severity score of 7.8.
The latter is a privilege escalation vulnerability in the SD-WAN management software used with a range of Cisco routers, including the vEdge 100 Series, 1000 Series, 2000 Series, 5000 Series, and Cloud Router. |

Todo o mundo There is no doubt that we live in fast times where things evolve quickly, sometimes even imperceptibly. The changes that take place are visible, especially in the business industry. What follows is the expanded spread of information. For this reason, many people want to make they keep track of work.
Nowadays, people can't imagine working without electronic devices such as computer, smartphone or tablet. But above all, computer was, is, and most likely will be the main tool for work. Hence, it's the computer that most people store all the information on, either when it comes to work or personal life. But when you think about all the data and information that you access every single day from this amazing device, it's easy for a headache.
People don't give much attention to tracking what they do on the computer during the work day. If you do it for your own purposes on your equipment, you don't have to care about rules. You do it according to your needs. Unless you monitor your employees. Then, you have to do it in a smart way and don't breach security and privacy aspects. As long as you comply with the rules, it is a perfect method for enhancing employees' work and company performance! |

Todo o mundo Whether you are using a service provider for your broadband, private IP network, managed firewall, help desk support or cloud computing platform, each service provided by the third party is an independent service. It means that each service would actually require its own SLA with its own terms of service plus metrics negotiated on a case by case basis.
Having meaningful service level agreements in place helps to define the services and the performance that is expected from third party service providers. In most cases, the penalties or rebates that accompany the SLA are more trouble than they are worth.
The uptime, availability and performance of the service procured is far more valuable than the rebate. Most service providers will promote the fact that they have service level agreements in place for their services however, few will have the ability to effectively measure their service levels and even less will proactively provide service level performance information on a proactive basis. A well designed, implemented and maintained service level agreement can make a profitable investment made with a third party service provider. |

Todo o mundo This week, the coronavirus pandemic has seen a swathe of marketing campaigns paused or axed entirely, and the trend is likely to continue as more and more clients in retail, entertainment and hospitality stop trading. In advertising, 65% of execs expect the crisis to lead to layoffs in their company, according to research from Fishbowl.
This adds multiple layers of uncertainty to freelancers' weekly forecasts: will there be work? When will there be work? How can I plan for the financial year when no-one else can? Will my client's business fold before they can pay me before last month?
“We are facing an unprecedented time with unknowable outcomes,” said Nancy Van Brunt, head of talent success at Upwork. “Companies might be shifting their strategies and reprioritizing the projects currently on their roadmaps, but they are still in need of support.”
If you're a freelancer who's found themselves sitting on a canceled project, Van Brunt advises updating your portfolios and social profiles “to highlight how you can help clients through this time with your specific skill sets and experience” before reaching out to past clients with ideas.
Then, after hunting down any missing invoices, take the time to update your skill set, find a support network and start looking for new work. |

Todo o mundo Now you'll need to boot that Linux system. Restart your computer with the disc or USB drive inserted and it should automatically boot. If it doesn't, you may need to change your BIOS or UEFI firmware boot order, or select a boot device during the boot process.
If you're not sure whether you're running UEFI or BIOS, you're probably running UEFI, unless your PC is five years old or more. To enter your BIOS or UEFI on a desktop, you'll generally have to hit the Del or F12 key during the POST process (before Windows starts booting).
It can be a little trickier to get into the BIOS / UEFI on laptops. Many modern laptops don't give you the option to enter UEFI by keystroke. Some laptops may include a small, unlabeled button on the side that you can hold down while you turn on the laptop. If you're unsure about how to enter the UEFI setup screen, consult your PC's user manual.
On younger Windows PCs running Windows 10, you may have to disable Secure Boot before booting Linux. (Secure Boot has been a headache for many Linux users.) Most of the larger Linux distributions will boot normally with Secure Boot enabled, but others won't. |

Todo o mundo High-speed Ethernet is quickly becoming the networking norm as customer data-center servers grow to handle a ton of traffic from new, smarter applications, IoT devices, video and more.
According to IDC in the first quarter of 2018 overall 100Gb Ethernet revenue increased 83.8% year-over-year to $ 742.5 million and port shipments grew 117.7% year-over-year in the first quarter of this year. Researchers at Dell'Oro Group said they expect to see somewhere near 12 million 100G Ethernet ports ship this year compared to about 1 million 100G Ethernet ports shipped in 2016.
The need for increased data-center speeds is being driven by many things - the tremendous growth of hyperscale networks from players like Google, Amazon and Facebook, but also by the price / performance of 100G products, said Sameh Boujelbene, senior director at Dell ' Oro Group.
A recent study from PwC went a bit further in explaining how and why the network might need more speed. “Workloads are becoming less monolithic as companies branch away from the traditional enterprise data center. They are becoming more distributed, more mobile, and more like the workloads typically associated with hyperscale environments, ”PwC wrote. “… Almost all major workloads shifting from on-premises to public cloud in the next 1-3 years. Applications will be more tied to the network, and the network will become more critical given the distribution / dynamism of the workloads. ” |
